How do I invoice clients with multiple payment options in the US?

Understanding what “multiple payment options” really means

Invoicing with multiple payment options in the United States is less about adding a bunch of buttons and more about designing a payment experience that’s clear, compliant, and easy for clients to complete on the first try. “Multiple payment options” typically means you can accept more than one method—such as ACH bank transfer, credit/debit card, wire transfer, paper check, cash (in limited cases), and digital wallets—without confusing the client or creating extra reconciliation work for you.

In the US, clients vary widely in how they prefer to pay. A large company may require ACH and a formal remittance process. A small business might want to pay by card for points or cash flow. A consumer client may prefer digital wallets or cards. Your goal is to meet clients where they are while still maintaining consistent invoice formatting, accurate bookkeeping, and predictable cash flow.

A well-built invoicing workflow makes it obvious (1) what the client owes, (2) when it’s due, (3) how to pay, and (4) what to do if they have questions. When you offer multiple payment methods, you’re essentially reducing friction. But you also introduce more moving parts: fees, processing times, refund rules, chargebacks, and accounting categories. The good news is that you can standardize most of this with a repeatable invoice structure and a few smart policies.

Start with the right invoice foundation

Before you add payment options, make sure the invoice itself is structured correctly. In the US, invoices aren’t governed by a single national standard, but professional norms—and many corporate payables departments—expect certain details. A clear invoice reduces client back-and-forth and speeds up approval.

At a minimum, your invoice should include:

1) Your business name (or legal entity), address, and contact details.

2) The client’s name and billing address (and shipping/service address if relevant).

3) A unique invoice number that follows a consistent numbering system.

4) Invoice date and due date.

5) Itemized line items with descriptions, quantities, rates, and line totals.

6) Subtotal, discounts (if any), taxes (if applicable), and total amount due.

7) Payment terms (Net 7, Net 15, Net 30, Due on receipt, milestone-based, etc.).

8) A short payment instructions section, including multiple payment options.

9) Late fee policy (if you charge late fees), and any relevant notes (like purchase order numbers).

When you consistently present these fields, clients can route your invoice through their payables workflow quickly. If you’re using invoice24, treat templates as a way to enforce consistency: set up your default layout once, then adjust per client only when required.

Choose payment methods that match US client expectations

Offering “every payment method under the sun” isn’t always the best move. You want a set of options that covers most clients without creating administrative overhead. A practical US-focused set often includes:

ACH bank transfer: Great for B2B and larger invoice amounts. Lower fees than cards, fewer disputes than card chargebacks, and it fits corporate payment systems. Processing typically takes one to a few business days depending on the rails and banks involved.

Credit and debit cards: Convenient for clients, especially small businesses and individuals. Faster authorization, but you’ll generally pay processing fees and must manage chargeback risk.

Paper checks: Still common in some industries and among certain organizations. Slowest method and adds manual deposit steps, but sometimes it’s required by policy.

Wire transfer: Used for high-value payments or when a client insists. Typically same-day but comes with bank fees. Wires are more common for international payments but can still apply domestically.

Digital wallets (where applicable): Helpful for consumer-facing services and some small businesses, especially when clients prefer mobile-first payment experiences.

From a workflow standpoint, the most important thing is that each option is clearly described, and that your invoice makes the “best” option obvious. Many businesses subtly steer clients toward the lowest-cost option (often ACH) by labeling it as “preferred” or by offering a small discount for bank transfer on larger invoices.

Make payment instructions clear without overwhelming the client

The fastest way to slow down payment is to present too many instructions at once. The invoice should be easy to scan. Your payment section should be structured like a menu: a short “Pay now” area with primary options, followed by “Alternative methods” for the exceptions.

A simple approach is:

Pay online: Provide a secure payment link or button where clients can choose card or bank transfer.

Pay by bank transfer (ACH): Provide the banking details clients need (or an ACH authorization flow if you use one). If you provide bank details, be careful to format them neatly and consistently.

Pay by check: Provide the payee name and mailing address plus the memo line instruction (invoice number).

Pay by wire: Provide wire details separately if necessary, since wires can require different routing instructions than ACH.

If you include sensitive banking details, keep them in a well-defined area of the invoice, and avoid unnecessary repetition. Always instruct clients to include the invoice number as the payment reference to speed up reconciliation.

Use a “pay link” to let clients self-select methods

One of the easiest ways to offer multiple payment methods without adding clutter is to provide a single payment link. The client clicks it, chooses a method (ACH or card), and completes payment. This reduces mistakes and eliminates the need to copy bank details from the invoice. It also improves your chances of getting paid faster because the client can pay immediately from the email or PDF.

To make this work well, the payment link should lead to a page that clearly shows:

• Invoice number and amount

• What’s included in the payment (especially if partial payments are allowed)

• The available options (e.g., “Pay by bank transfer” and “Pay by card”)

• A receipt/confirmation step

From a business process perspective, this approach also makes reconciliation easier because payments can automatically attach to the invoice record. In invoice24, you can design your workflow so that the invoice status updates when the payment is completed, and you can keep a unified view of all transactions regardless of payment type.

Decide whether to pass on processing fees

When you accept multiple payment methods, fees become a real consideration—especially for card payments. In the US, businesses commonly handle this in one of three ways:

1) Absorb fees and set pricing accordingly: You build expected fees into your rates and keep the checkout experience simple. Clients like this because the invoice total is the final total.

2) Offer a “preferred” low-fee method and keep others optional: You encourage ACH by labeling it “preferred” or by noting that it’s fee-free (for you and possibly for them). Cards remain available for convenience.

3) Surcharge or convenience fee for cards (where permitted): Some businesses add a card surcharge to offset fees, but you must follow card network rules and applicable state laws and disclosure requirements. Because these rules can vary and change, many businesses prefer option 1 or 2 for simplicity.

Regardless of approach, be transparent. If the client sees the total unexpectedly change at payment time, it can delay approval and erode trust. A good practice is to keep the invoice total consistent and, if you add fees for certain payment methods, disclose it clearly before the client commits to paying.

Offer partial payments, deposits, and payment plans when appropriate

Multiple payment options aren’t only about methods; they’re also about timing. In the US, many service providers and freelancers reduce risk by collecting a deposit upfront and the remainder on completion or at milestones. Offering payment plans can also increase close rates for larger projects.

Common structures include:

Deposit + balance: Example: 50% due upfront, 50% due upon delivery.

Milestone billing: Example: 30% on kickoff, 40% after milestone one, 30% at final delivery.

Monthly retainer: A recurring invoice with a set amount due each month.

Installments: A fixed number of payments over a defined period.

To invoice successfully with these models, your invoices should clearly identify what the payment represents (deposit, milestone, installment) and how it affects the remaining balance. If you allow partial payments, specify whether the invoice remains open until paid in full and whether late fees apply to the unpaid portion.

In invoice24, you can keep the client’s view simple by showing the current amount due, prior payments, and remaining balance. That clarity prevents confusion and reduces “Did you get my payment?” emails.

Set payment terms that fit your client type

Payment terms are not just administrative—they shape cash flow. In the US, Net 30 is common for B2B, but it’s not always ideal for small businesses. Many freelancers and small agencies use Net 7 or Net 15, especially for smaller invoices. For consumer clients, “due on receipt” or a short due window can make more sense.

Practical guidance:

For new clients: Consider shorter terms or deposits until trust is established.

For enterprise clients: They may require Net 30 or Net 45 and a vendor onboarding process. Build that into your planning.

For high-demand services: Shorter terms are easier to enforce, and clients often accept them if you communicate upfront.

For recurring relationships: A consistent monthly schedule (invoice on the 1st, due on the 15th, for example) can reduce delays.

Whatever terms you choose, put them on the invoice and in your contract or proposal. The invoice should never be the first time a client sees your payment expectations.

Include the right details for ACH and wire payments

Bank payments can be fast and inexpensive, but they require accurate information. For ACH in the US, clients may need your routing number and account number, and sometimes the account type (checking/savings). For wire transfers, the bank’s wire routing information may differ from the ACH routing number, and additional fields might be required.

To reduce errors:

• Label sections clearly: “ACH (Bank Transfer)” vs “Wire Transfer.”

• Use consistent formatting with line breaks and spacing.

• If your bank provides separate instructions for ACH and wires, keep both but avoid mixing fields.

• Ask clients to include the invoice number in the payment memo or reference field.

• Consider limiting wire instructions to clients who need them, rather than including wire details on every invoice.

Also consider the security angle: invoices are often emailed and forwarded. If you include full bank details, clients could accidentally expose them internally. Many businesses prefer a secure payment link that handles ACH enrollment and reduces the need to print bank account numbers on documents.

Make card payments painless and reduce chargeback risk

Card payments can speed up collections, but they come with dispute risk. To reduce chargebacks and payment friction:

Use clear descriptions: Line items should match what the client expects based on your proposal or contract.

Use recognizable business names: If your brand name differs from your legal entity, make it visible on the invoice so the charge is familiar when they review statements.

Send receipts automatically: A payment confirmation helps clients reconcile expenses and reduces the chance they forget why they paid.

Document delivery and acceptance: For services or digital deliverables, keep records of what was delivered and when. This is useful if a dispute occurs.

Use policies for refunds and cancellations: A short policy statement (and a link to your full policy if you have one) can set expectations.

When offering both cards and ACH, it often makes sense to display ACH first as the “recommended” option, and cards as “pay by card” for convenience.

Handle sales tax and compliance considerations

Invoicing in the US can involve sales tax, but whether you must charge it depends on your business type, what you sell, where you have nexus, and the client’s location. Some services are taxable in certain states and not in others. Some products are exempt. Some customers may be tax-exempt with valid documentation.

From an invoicing perspective, the key is to make tax line items clear. If you charge sales tax, show it separately rather than burying it inside the total. If the client is exempt, you might include a note such as “Tax-exempt customer” and keep a record of their exemption certificate.

Even if you don’t charge sales tax, invoices should still be professional and consistent. For many businesses, the invoice is a tax record and must be kept for accounting and audit purposes. Maintain a clear numbering system and preserve invoice copies and payment confirmations.

Use purchase orders, vendor onboarding fields, and client-specific requirements

Many US business clients require a purchase order (PO) number or specific billing references to approve payment. If you don’t include these, the invoice may be rejected or delayed.

Best practices include:

• Add a dedicated “PO Number” field on the invoice.

• Ask for the PO number before starting work, not after invoicing.

• Match the client’s legal name and billing address exactly as their payables department expects.

• If the client requires net terms, a vendor ID, or department codes, include those fields in a consistent “Client References” section.

• If the client uses a portal, ask whether you should send invoices by email, upload them, or both.

With invoice24, you can save client-specific defaults so you don’t have to remember them each time. The smoother your compliance with their process, the faster you get paid.

Design invoices for email delivery and easy viewing

Most invoices are delivered by email, and many are viewed on phones. That reality should influence formatting. A beautifully formatted invoice that’s hard to read on mobile can slow down approvals.

Practical formatting tips:

• Keep the top section clean: your branding, invoice number, dates, and the amount due should be easy to find.

• Use short, scannable line-item descriptions.

• Put payment options near the total due—don’t force the client to hunt for instructions.

• If using a payment link, make it prominent and labeled clearly (e.g., “Pay this invoice online”).

• Avoid overly long paragraphs in the invoice notes. Save detailed contract language for your agreement, not the invoice.

When you send invoices, include a short email message that repeats the essentials: invoice number, amount due, due date, and how to pay. Clients often pay from the email itself rather than opening attachments.

Automate reminders without sounding robotic

Offering multiple payment options helps, but you still need a follow-up system. Many late payments are not intentional—an invoice gets buried, someone is out of office, or the payables workflow stalls. Automated reminders are one of the highest-leverage tools for consistent cash flow.

A practical reminder cadence for US clients might look like:

• Reminder 3–5 days before due date: friendly heads-up with the pay link.

• Reminder on due date: short message noting it’s due today.

• Reminder 3–7 days after due date: polite but direct follow-up, ask if they need anything for processing.

• Reminder 14+ days late: escalate tone, reference late fee policy if applicable, and ask for a payment date.

The key is tone. You want to preserve the relationship while being clear. Messages should assume good intent and offer help: “If you need a W-9, vendor form, or updated invoice, reply here.” That small line can remove a common blocker.

Make reconciliation easy across payment methods

When you accept multiple payment methods, the back office can get messy—unless you standardize reconciliation. Reconciliation is simply matching money received to the correct invoice and client record. You want to reduce “mystery payments” that arrive without references.

Use these tactics:

Always require invoice number as reference: Put “Include invoice number on payment memo” on the invoice for ACH/check/wire.

Use unique invoice totals (when feasible): If a client is paying multiple invoices, ask them to pay separately or provide a remittance advice email listing which invoices are included.

Record payment method: Store whether it was ACH, card, check, or wire. This helps when you review fees, processing times, and client behavior.

Centralize receipts: Send an automatic receipt for each payment, and store it with the invoice record.

Track fees separately: Card processing fees should not distort revenue figures. Keep them categorized as payment processing expense in your accounting system.

With invoice24, aim for a workflow where each payment is linked to an invoice automatically when possible, and easy to match manually when needed.

Plan for refunds, credits, and adjustments

Multiple payment options also mean multiple refund paths. Refund policies can vary by method, and timing can differ. Even if you rarely refund, you should be ready for common scenarios: overpayment, project scope change, canceled work, or goodwill credits.

Best practices:

• Use credit notes for adjustments rather than deleting invoices.

• Keep an audit trail: original invoice, payment record, credit note, and revised balance.

• If a client overpays, ask whether they want a refund or to apply it as credit to the next invoice.

• If you accept card payments, be aware that refunds can take several business days to appear on the client’s statement.

• For ACH and wires, refunds may require you to collect client banking details; handle that securely and confirm details carefully.

A professional adjustment process builds trust. Clients appreciate clear documentation, and it reduces confusion during tax time.

Reduce fraud and “invoice interception” risk

Invoicing fraud is a real issue: scammers sometimes impersonate vendors and send “updated banking details” to redirect payments. When you accept bank transfers and wires, you should take steps to reduce this risk for both you and your clients.

Good safeguards include:

Establish a banking change policy: If your bank details ever change, tell clients you will confirm changes via a known phone number or a pre-agreed channel—not just email.

Keep client contacts updated: Ensure invoices go to the right billing contacts and not to general inboxes where spoofing is easier.

Use secure payment links: A pay link that is consistent and branded helps clients recognize legitimate payment paths.

Encourage verification for large payments: For high-value invoices, encourage the client’s payables team to verify payment instructions through a second channel.

You don’t need to alarm clients, but a simple note like “We will never email new banking details without verification” can prevent costly mistakes.

Create client-specific payment option sets

Not every client needs every payment method. If you offer all options to everyone, you may increase confusion. A smarter approach is to create client profiles that define the default payment methods you present.

Examples:

Enterprise client profile: ACH preferred, wire optional, check as backup, card disabled if they won’t use it.

Small business profile: ACH and card enabled, pay link prominent, check optional.

Consumer client profile: Card and digital wallets, pay link front and center, no bank details shown.

When you tailor options, the invoice looks cleaner, and clients are more likely to choose the method that works best for both sides.

Use clear language for payment terms and late fees

In the US, late fees are common in B2B, but how you apply them matters. If you plan to charge late fees, include your policy in a short, plain-language line on the invoice and ensure it matches your contract. Keep it simple and unambiguous.

For example, your invoice notes might clarify that payments are due by the due date and that late fees may apply after a certain number of days. You can also state that work may pause on overdue balances if that is part of your business policy.

The purpose isn’t to be harsh—it’s to prevent misunderstandings and to give you a professional basis for follow-up if payment is significantly delayed.

Offer a frictionless experience for repeat clients

Repeat clients are the easiest to serve and the most valuable for cash flow. For them, your invoicing goal is to make paying feel routine. Once you know a client’s preferred payment method, set it as default and keep everything else consistent.

Ways to streamline repeat payments:

• Send invoices on a predictable schedule.

• Use consistent invoice numbering and descriptions.

• Include the same payment link placement every time.

• Keep billing contacts up to date.

• Use saved products/services to avoid description drift.

If a client always pays by ACH, prioritize those instructions. If they always pay by card, make that option quick and ensure receipts are easy for their records. Small improvements compound over time.

Build a simple internal checklist for every invoice

Even with great software, mistakes happen when you’re busy. A short checklist prevents the most common issues that slow payment:

• Correct client name and billing address

• Correct email recipient (accounts payable or finance contact)

• Correct invoice number and dates

• Correct line items, quantities, and rates

• Correct taxes and discounts

• PO number and any client references included

• Payment options visible and accurate

• Payment link works

• Notes and terms match the agreement

Running this checklist takes less than a minute and can save days of delay.

Example payment options section you can adapt

You can structure your payment options area like this in a clean, client-friendly way:

Payment options:

Pay online: Use the secure payment link included with this invoice to pay by bank transfer (ACH) or credit/debit card.

Bank transfer (ACH): Include the invoice number as the payment reference.

Check: Make checks payable to your business name and write the invoice number in the memo line.

Wire transfer (if needed): Available upon request for high-value payments or corporate requirements.

This format gives clients a clear first choice while still supporting exceptions.

Troubleshooting: why clients don’t pay even with multiple options

If you’ve added multiple payment methods and payments are still slow, the problem may not be the payment rails. Common blockers include:

Invoice approval delay: The client’s internal approval process is slow. Solution: ask if they need a PO number, vendor form, or W-9; confirm their payables timeline.

Invoice went to the wrong person: It’s stuck in a busy inbox. Solution: confirm the correct billing contact and resend.

Unclear scope or line items: The invoice doesn’t match expectations. Solution: improve descriptions and reference the project or agreement.

Payment link friction: Too many steps or a confusing page. Solution: simplify the payment page and highlight the most used method.

Client cash flow issues: They’re prioritizing other bills. Solution: offer a payment plan or partial payment arrangement, and get a firm payment date.

Multiple payment options help, but clarity and process usually matter more than adding yet another method.
