Can I claim expenses for business-related online booking systems?

Online booking systems have become a near-default tool for many modern businesses. Whether you run a hair salon, a physiotherapy clinic, a holiday-let, a tutoring service, a consultancy that schedules client calls, or a small events company, the ability for customers to book appointments and pay online can save time, reduce no-shows, and improve cashflow. With that convenience comes an ongoing cost: monthly subscriptions, payment processing fees, add-ons for messaging reminders, and sometimes setup or implementation charges. A common question for business owners is simple: can those costs be claimed as business expenses?

In most ordinary situations, yes: if the booking system is used for business purposes and the costs are incurred “wholly and exclusively” for the business, they are typically allowable as a business expense. The real-world answer, however, depends on your business structure, how you use the system, what exactly you are paying for, and how you keep records. It also matters whether the booking system purchase is treated as a regular running cost (a revenue expense) or a longer-term investment (a capital cost) that might need to be dealt with differently for tax.

This article walks through how business-related online booking system costs are usually treated, what types of charges often qualify, where things can get tricky, and how to keep your bookkeeping clean so you can claim confidently.

What counts as an “online booking system” expense?

The phrase “online booking system” covers a lot of products and services. At the simplest end, it might be a basic scheduling tool that lets customers reserve a slot in your calendar. At the more advanced end, it could be a full practice-management or venue-management platform that combines scheduling, staff rotas, CRM, automated reminders, online intake forms, membership billing, deposits, reporting, and integrations with accounting software.

Typical costs include:

1) Subscription fees (monthly or annual) for the booking platform.

2) Per-user charges if you pay by staff member or by resource (e.g., per therapist, per room, per instructor).

3) Transaction fees or payment processing charges for taking online deposits or full payments.

4) Add-ons such as SMS reminders, marketing automation, email campaigns, or advanced reporting.

5) Setup fees, onboarding charges, or implementation costs charged by the provider.

6) Customisation costs, such as branded booking pages, domain mapping, or API access.

7) Integration costs, for example connecting to your website, point-of-sale, calendar systems, or accounting software.

8) Support plans or premium service levels.

Many businesses also pay related expenses that sit alongside the booking system, such as website hosting, domain renewal, email services, and payment gateways. These may still be claimable, but it helps to understand which costs are “booking system” charges and which are broader digital running costs.

The general rule: the expense must be for business purposes

Most tax systems work from a similar principle: you can generally deduct expenses that are incurred for the purpose of running your business, so long as they are genuine, properly recorded, and not personal in nature. Booking systems are usually used to secure sales and manage operations, so they typically have a clear business purpose.

Problems arise where there is mixed use (some personal, some business), or where the payment includes elements that are not purely business costs. For example, if you use one subscription to manage your business appointments and also to schedule personal appointments, then you may need to apportion the cost and only claim the business portion.

In practice, many businesses keep it simple by using business-only tools and accounts. If your booking system is used exclusively for business clients, appointments, classes, or room hire, then claiming the full cost is usually straightforward.

Revenue expense vs capital expense: why it matters

In bookkeeping and tax, there is an important difference between expenses that relate to day-to-day running (revenue expenses) and costs that create an asset or long-term benefit (capital expenses). This distinction can affect how and when you get tax relief.

Revenue expenses are the ongoing costs of operating your business—things like subscriptions, routine software fees, and standard transaction charges. These are usually deducted against income in the period they are incurred.

Capital expenses are costs that create or improve an enduring asset, or that bring lasting value beyond the short term—such as building a bespoke booking platform, developing a custom plugin, or paying significant one-off implementation costs that fundamentally create a new system rather than maintaining one.

Most off-the-shelf online booking systems are subscription services. The subscription fee is commonly treated as a revenue expense because you are paying for access month-by-month or year-by-year, not buying the software outright. However, one-off setup or custom development costs can sometimes drift into capital territory, especially if you are paying for something that is tailored and will be used over multiple years.

If your booking system costs are clearly subscription-based, you are usually in the revenue expense zone. If you have paid a developer a large sum to build a bespoke booking portal, integrate it deeply into your website, and create custom functionality that will remain yours, you may need to treat it differently.

Common claimable costs for online booking systems

Here are the charges that are most commonly claimable when they are used for business purposes:

1) Monthly or annual subscriptions

If you pay a recurring fee for a scheduling or booking platform, that is typically an ordinary business cost. It is similar in nature to other digital services such as accounting software, email hosting, or project management tools. If the tool is used wholly for your business, claiming the full subscription is usually uncomplicated.

2) Add-ons and premium features

Many platforms offer add-ons such as automated reminders, class passes, loyalty schemes, packages, waitlists, or marketing tools. If you pay extra for these features to help your business operate or generate revenue, those costs are usually claimable.

3) Payment processing fees

When customers pay online, your payment processor may deduct fees per transaction (for example, a percentage plus a fixed amount). These fees are generally part of the cost of taking payments and can often be treated as business expenses.

Be careful with how you record them. Some platforms show the fee as a separate line item, while others net the fee off the amount you receive. Good bookkeeping means recording gross income and recording the processing fees as an expense, rather than only recording the net amount received. This gives a clearer picture of your sales and costs.

4) Setup and onboarding fees

If a provider charges a one-off onboarding fee—such as a fixed setup payment for initial configuration, templates, staff accounts, and basic training—this is often still treated as a revenue expense, especially if it is modest and directly connected to putting a subscription service in place.

However, if setup fees are large and relate to building a custom system or significant development work, you may need to consider whether some of that cost is capital in nature.

5) Integration costs and small development work

If you pay a freelancer to embed the booking widget on your website, set up tracking, connect calendars, or configure your booking page branding, those costs are often treated as routine business expenses—especially if they are minor and do not create a standalone asset.

But if you are commissioning substantial software development that goes beyond configuration and creates a custom product, the line can shift.

6) Support plans and training

Premium support plans, staff training fees, and consultancy sessions that increase your ability to use the booking system effectively are commonly claimable as business expenses, provided they are business-related. Training that helps you operate your business software is generally an ordinary running cost.

When you might need to split (apportion) the expense

Not every business tool is used purely for business. If your booking software is used partly for personal use, you may need to claim only the business proportion. This could apply in situations such as:

• A sole trader using a scheduling tool for paid client sessions and also for personal time-blocking and family appointments.

• A coach who runs both business coaching sessions and unpaid personal community events through the same system.

• A landlord using a “booking” platform for a holiday-let business while also using it to manage personal property bookings for friends.

How do you apportion fairly? A reasonable approach is to base the split on usage, such as the proportion of appointments that are business-related. For example, if 90% of the booked appointments are business clients and 10% are personal, you might claim 90% of the subscription fee. It is important to use a method that you can justify if ever queried.

If the personal element is negligible, some businesses still claim the full cost, but that carries risk. The safer route is to keep business tools business-only. Using separate accounts and separate tools reduces complexity and keeps your position clearer.

What if the booking system includes a website or domain?

Some booking providers sell bundled packages that include a mini-website, domain, hosting, or a “link in bio” style page. Others include a branded subdomain or charge extra for custom domain mapping. Generally, website hosting and domain costs can also be business expenses if they are used for your business.

Where it becomes more nuanced is if the package includes items that are partly personal (for example, a personal email domain that you also use for non-business communications). If everything is business-branded and business-used, it is usually simpler.

If you buy a package that includes multiple digital services (booking + email marketing + website builder), it can help to keep the invoices and plan details so you can explain what the payment covered and why it is business-related.

How different business structures can affect the claim

The underlying idea is the same across most structures—business costs are deductible—but the mechanics vary depending on whether you operate as a sole trader, a partnership, or a limited company (or similar incorporated entity in your jurisdiction).

Sole traders and partnerships

If you are self-employed, you typically claim business expenses against your business income, reducing taxable profit. The key is that the cost must relate to the business and be properly recorded. Mixed-use requires apportionment, as discussed above.

Limited companies

If you run a company, the company usually pays for the booking system and claims it as a company expense, reducing corporation tax profits. If you personally pay for it and then reclaim it from the company, you should keep clean records and ensure it is treated as an expense reimbursement rather than personal spending.

A company structure also increases the importance of keeping expenses wholly for business. If you use the company-paid booking system for personal use, you may create a benefit-in-kind or a need to treat part of it as personal, depending on local rules. Practically, companies should keep subscription services clearly business-only to avoid complications.

Is software always an allowable expense?

Most business software that supports administration, sales, client management, or operations is commonly allowable. Online booking systems fall within that broad category. The fact that the software is digital or cloud-based does not usually prevent it being a deductible expense. In many businesses, booking software is directly tied to revenue: without it, customers may not be able to book and pay conveniently.

Where caution is needed is when the “software” is actually part of a larger project—such as building a custom platform or acquiring a long-term asset. A straightforward subscription is usually fine; a major development build may require different treatment.

Booking system hardware and related tech costs

Sometimes the booking platform is only one part of the operational setup. You might buy a tablet for reception, a dedicated phone, a card reader, or a computer used to manage bookings and check customers in. These costs are not booking system fees, but they are related.

Whether they are deductible as revenue expenses or treated as capital purchases depends on the nature of the item. A subscription is typically a revenue cost; a tablet or computer may be treated as equipment, potentially subject to capital allowance rules or depreciation treatment, depending on your accounting method and local regulations.

If you are looking at your booking system as part of a wider “digital operations” spend, it is worth separating software subscriptions from physical equipment in your bookkeeping, because they may be treated differently for tax and reporting.

Handling refunds, cancellations, and chargebacks

Online booking systems often involve deposits, cancellation fees, refunds, and occasionally chargebacks. The expense side (subscription and fees) is usually claimable, but it’s important to record the income side correctly too.

Consider these common scenarios:

Refunds: If you refund a client, you should record the refund as a reduction of income or as a separate refunds line, depending on your bookkeeping approach. If payment processing fees are not returned, those fees remain an expense.

Chargebacks: If a client disputes a payment and the processor takes the money back (and charges an additional fee), you will need to record both the loss of income and the chargeback fee. Chargeback fees are generally operating costs associated with taking card payments.

No-shows and cancellation fees: If your booking system helps you enforce cancellation policies and collect fees, the income is still business income. The software fees that support that revenue generation are typically claimable costs.

Good records matter here because online systems can create a lot of small transactions. Clear reporting from your booking platform, reconciled to your bank and accounting software, is one of the best ways to avoid confusion at tax time.

How to record online booking system expenses in your accounts

Clean bookkeeping makes claiming easier and reduces the risk of errors. A few practical tips help:

1) Use a dedicated expense category

Create a ledger category such as “Software subscriptions,” “Booking software,” or “Online services.” If you have multiple software tools, you might keep them under one umbrella category, but some businesses prefer a separate category for booking and payment platforms because they are so closely linked to sales.

2) Keep invoices and receipts

Most providers email invoices or make them available in an online billing portal. Download them periodically or ensure you can access them later. If your provider only produces a monthly receipt, keep that. A bank statement line is helpful but is not always sufficient on its own, especially if the provider name is unclear.

3) Record the correct dates

If you pay annually upfront, you may need to consider whether you expense it immediately or spread it across the year, depending on your accounting method and local rules. Many small businesses expense when paid (cash basis), while others match the cost to the period it relates to (accrual basis). Consistency is important.

4) Separate fees from income when possible

If the platform nets fees off your payouts, consider recording gross sales and then recording fees separately. This makes your true revenue and cost structure clearer. It can also help you compare processors and understand your margins.

5) Document your apportionment method if mixed-use

If you claim less than 100% due to personal use, note the method you used (for example, “10% personal use based on appointment counts over a three-month sample”). This doesn’t need to be complex, but a simple note can save time later.

VAT or sales tax considerations

Taxes on the invoice (such as VAT, GST, or sales tax) can affect how you claim the expense. The treatment depends on whether you are registered and whether the supplier charges tax correctly for your location. For example, software providers may be based abroad, and digital services can have specific place-of-supply rules that affect how tax is charged or accounted for.

If you are registered for VAT (or equivalent), you may be able to reclaim VAT on the subscription if the invoice meets the requirements and the purchase is for business. If you are not registered, the tax becomes part of the cost to you.

Because cross-border digital services can be complicated, especially when the supplier is in another country, it is worth checking how your invoices are being issued and whether you need to apply any special accounting treatment. Many accounting packages have features for handling overseas digital services, but the correct approach depends on your circumstances.

When an online booking system cost might not be fully claimable

Even though booking systems are usually business-related, there are circumstances where the cost may be disallowed, partially disallowed, or challenged. Common examples include:

Primarily personal use: If the tool is mostly used for personal scheduling with only occasional business use, claiming the whole subscription would be hard to justify. You would normally claim only the business portion.

Dual-purpose spending: If the system is used both for a business and for an unrelated personal project, you may need to apportion. The more distinct the activities, the clearer the split should be.

Entertainment or non-business features: Some platforms bundle marketing or community features that are not directly business-related, or offer optional tools that are essentially personal convenience. If the add-on isn’t genuinely for the business, it may not be claimable.

Unclear records: If you cannot provide invoices or explain what the costs relate to, you increase the risk of disallowance in a review or audit. Recordkeeping is often the deciding factor in borderline cases.

Capital nature of the spend: If you pay for extensive custom development, it may not be treated as a simple deductible expense in the year of payment. It may need to be capitalised and handled differently.

Capital projects: building or buying a bespoke booking system

Some businesses outgrow subscription platforms and commission a bespoke booking solution, perhaps integrated into their own website and database. The costs may include developer fees, project management, design, testing, and long-term maintenance. This is where you need to be more careful, because a bespoke build can be considered a capital asset or an intangible asset, depending on how ownership and rights are structured.

If you are paying for a custom solution that you own and that will provide value over several years, the cost might not be treated the same as a monthly subscription. You may still get tax relief, but it may come through a different mechanism, spread over time, or treated under specific rules for software development and intangible assets.

Even within a bespoke build, not all costs are equal. Routine maintenance fees, hosting, and ongoing support are often still revenue expenses. The initial build costs may be capital. The dividing line depends on the specifics of the work, contracts, and local tax rules.

If you are planning a significant custom development project, it’s wise to keep contracts and scope documents and to separate invoices between “build” and “maintenance/support” where possible. Clear separation makes the accounting treatment much easier.

Practical examples

Sometimes examples make the principles clearer. Here are a few scenarios and how the expense is usually approached:

Example 1: A yoga studio using a subscription platform

A yoga studio pays a monthly fee for a booking system that lets members schedule classes, buy class packs, and receive automated reminders. The system is used exclusively for the studio. The monthly subscription and the SMS reminder add-on are typically claimable business expenses. Payment processing fees deducted on online class purchases are also typically claimable as transaction costs.

Example 2: A self-employed consultant using a scheduling tool for business and personal use

A consultant uses a scheduling tool to let clients book calls, but also uses it to schedule personal reminders and family appointments. The subscription has mixed use. A reasonable approach is to claim the portion that relates to business usage—perhaps based on the proportion of booked events that are client calls.

Example 3: A salon paying for setup and staff training

A salon signs up to a booking platform and pays a one-off onboarding fee, plus a training session for staff. If the onboarding is simply getting the subscription service configured and staff trained, those costs are usually treated as business expenses. If the salon also pays a developer to build a bespoke integration that creates a custom client portal, the custom development might require different treatment.

Example 4: A holiday-let business paying platform fees

A property owner runs a holiday-let business and uses an online booking platform that charges a subscription plus transaction fees. Provided the activity is a genuine business, the platform fees can generally be treated as business expenses. If the owner also uses the platform for private stays or family bookings that are not part of the business, they may need to apportion the cost.

How to make your claim robust

If you want to feel confident that you can claim the cost of a business-related online booking system, focus on three things: purpose, evidence, and consistency.

Purpose: Make sure the tool is actually used to run or grow your business. If it is integral to taking bookings, managing appointments, collecting payments, or reducing admin, that is a strong business purpose.

Evidence: Keep invoices, receipts, plan details, and proof of payment. If your platform provides usage reports, you don’t necessarily need to store them routinely, but it can help to know they exist in case you ever need to demonstrate business use.

Consistency: Record the expense consistently in your accounts. If you change from monthly to annual billing, make a note. If you apportion the cost due to mixed use, apply the method consistently and update it if usage patterns change.

Which category should it go under in your bookkeeping?

Many businesses record booking software under “Software subscriptions” or “Computer software.” Payment processing fees may sit under “Bank charges,” “Merchant fees,” or “Card processing fees.” SMS reminder costs might be under “Telephone and communications” or still under software subscriptions, depending on your chart of accounts.

The exact label matters less than clarity and consistency. The goal is that you (and your accountant or bookkeeper, if you have one) can quickly see what the cost relates to and reconcile it back to invoices and payments.

What about free booking systems or freemium plans?

Some providers offer free tiers where you pay only transaction fees, or you pay for optional add-ons. If you don’t pay a subscription, you obviously won’t claim a subscription expense, but you can still claim any fees you do incur that are business-related—such as payment processing charges or add-on costs.

If the platform is “free” because it includes advertising or pushes you into upsells, there may be no direct subscription expense to claim, but your business still benefits from a tool that supports sales and operations. From an accounting perspective, you only claim what you actually pay.

Can you claim expenses if you are just starting out?

Many businesses subscribe to booking tools before they have their first customer, particularly if they are preparing a launch. In many cases, pre-trading or start-up costs that are incurred wholly for the purpose of the new business can still be claimable, depending on local rules and timing. Examples include setting up your booking page, integrating with your website, and testing the payment process prior to launch.

The key is that the expense is genuinely connected to establishing the business and is not a personal cost. Keeping good records from day one—saving invoices and noting the business purpose—can make a big difference when you later prepare your first tax return or annual accounts.

Questions to ask yourself before claiming

If you are unsure whether your booking system costs are claimable, these questions help you assess your position:

• Is the booking system used to generate or manage business income?

• Is it used wholly for business, or is there personal use as well?

• Do you have invoices and proof of payment?

• Are you paying a simple subscription, or have you commissioned a bespoke build?

• Are the payment processing fees recorded clearly, separate from income where possible?

• If you are registered for VAT or sales tax, are invoices correctly issued and recorded?

If the answers point clearly to business use and good documentation, the expense is usually straightforward.

Common mistakes to avoid

Booking system expenses are typically not controversial, but mistakes happen in the details. Here are frequent pitfalls:

Only recording net payouts: If your platform deducts fees and pays you the remainder, recording only the net amount can understate sales and hide processing fees. Better records usually mean recording gross sales and fees separately.

Mixing personal and business subscriptions: Using one account for everything creates ambiguity. Separate tools or separate accounts reduce the need for apportionment.

Losing invoices: Providers sometimes limit access to old invoices or change portals. Download invoices periodically and store them with your accounts records.

Misclassifying large development projects: Treating a large bespoke software build as a simple expense without considering capital treatment can cause issues later. Separate “build” from “maintenance” and keep contracts.

Forgetting currency conversion: Many software providers bill in a foreign currency. Record the amount paid and the relevant exchange rate according to your accounting method. This is especially important if you want your accounts to reconcile precisely.

So, can you claim expenses for business-related online booking systems?

For most businesses, the practical answer is yes. If you pay for an online booking system to run your operations, take appointments, manage capacity, and receive customer payments, those costs are generally ordinary business expenses. Subscription fees, add-ons, transaction charges, and support plans are commonly claimable when they are incurred for business purposes.

The main caveats are mixed personal use (which may require apportionment) and large bespoke development work (which may require different treatment than a simple subscription). Keeping clear invoices, recording fees properly, and using business-only accounts wherever possible will make your claim much stronger and your bookkeeping simpler.

If you ever find yourself unsure—particularly around VAT/sales tax handling for overseas software providers or around capital-versus-revenue treatment for major custom projects—getting advice from a qualified accountant or tax adviser can save time and reduce risk. But for the typical small business paying a monthly fee for a cloud booking platform, claiming the cost as a business expense is usually one of the more straightforward parts of running the numbers.
