Question 1

How do I invoice for labour and materials separately?

Accepted Answer

Add one line item per block of labour (e.g. "Labour — general repairs & maintenance") and a separate line for each material or supplied part. This is universal good practice and is required for UK CIS, German §35a, Swedish ROT-avdrag and several other schemes that rely on seeing the labour cost in isolation.

Question 2

Do contractors or handymen charge sales tax on labour?

Accepted Answer

In much of the US, a contractor doing real-property work under a lump-sum contract is treated as the consumer of materials — sales tax is paid on the materials purchase, not charged again to the customer, and labour on a lump-sum job is usually untaxed. But itemized time-and-materials contracts flip this in several states (e.g. AZ, CO, TX), taxing the material lines. Check your state's rule and use the per-line taxable flag accordingly.

Question 3

How do I show a CIS deduction on my invoice?

Accepted Answer

Add a negative, non-taxable line item such as "Less CIS deduction (20% of labour)" — for a registered subcontractor HMRC requires 20% withheld from the labour element only (never materials, plant hire or VAT); unregistered subcontractors have 30% withheld. VAT, if charged, is calculated on the full amount before the CIS deduction is applied.

Question 4

What is a reverse charge invoice in construction?

Accepted Answer

When a subcontractor invoices another business within a construction supply chain, several countries shift responsibility for the VAT to the customer instead of the supplier. The UK's domestic reverse charge (VAT Act 1994 s.55A), Germany's §13b UStG, Austria's §19 Abs. 1a, the Netherlands' "btw verlegd" and Finland's AVL 8c § all work this way: the invoice shows 0% VAT plus a mandatory statement that the customer accounts for the tax directly.

Question 5

Can I invoice without being VAT/GST registered?

Accepted Answer

Yes, as long as you're under your country's registration threshold (e.g. UK £90,000, Australia AU$75,000) — simply don't charge VAT/GST on the invoice. In Australia, invoices without an ABN can trigger 47% no-ABN withholding by the payer, so include your ABN even if you're not GST-registered.

Question 6

How much deposit should a contractor ask for, and how do I show it?

Accepted Answer

Deposit amounts vary by job size and local norms — many trades ask for 10–50% up front on larger jobs. Add it as a negative, non-taxable line item (e.g. "Less deposit received") so the balance due calculates correctly against the full taxed total.

Question 7

Should I mark up materials, and does the markup show on the invoice?

Accepted Answer

Most contractors bake a materials markup (commonly 10–20%) directly into the unit price rather than showing it as a separate line — a visible "markup" line tends to invite disputes, while a single itemized unit price for the material does not.

Question 8

What must be on the invoice for my customer to claim a home-improvement tax credit?

Accepted Answer

Schemes like Germany's §35a EStG, Sweden's ROT-avdrag, Finland's kotitalousvähennys and Denmark's reinstated håndværkerfradrag all require the labour cost to be shown separately from materials, and usually require electronic (non-cash) payment. Keep every labour line distinct from every materials line and your customer's claim is far less likely to be rejected.

Question 9

How is this different from the construction invoice generator?

Accepted Answer

This tool is built for small jobs and service/repair work — one contractor or handyman billing a homeowner or property manager for a day's or week's work. The construction invoice generator is built for larger multi-trade projects that bill in stages, with progress/milestone invoicing, retention (retainage) and subcontractor chains. If you're issuing periodic applications for payment against a contract sum, use the construction generator instead.

Question 10

How is this different from the freelance invoice generator?

Accepted Answer

This tool assumes physical, on-site trade work — it has a job/site address and a labour/materials split baked in. The freelance invoice generator is built for knowledge work (design, writing, consulting, development) billed by the hour or project, with no site address or materials line. If you're a self-employed knowledge worker rather than a tradesperson, use the freelance generator.

Question 11

Do I need a licence or insurance number on the invoice?

Accepted Answer

It depends on your market: several US states expect a contractor license number on invoices/contracts, France legally requires décennale (10-year) insurance details on quotes and invoices, and Australia effectively requires an ABN to avoid no-ABN withholding. Add your licence number in the header field provided if your market expects one.
