How to make a consultant invoice
- Pick your country. Use the country selector in the editor to set the currency, date format and tax labels. The sample lines below are only a starting point for consultants.
- Enter your business details. Add your name, address, contact details, tax or registration number and a logo if you have one. Save them as a business profile to reuse next time.
- Add the customer. Enter the customer’s name and address, and a PO or job reference if they gave you one. Save the customer for repeat jobs.
- Edit the line items. Replace the sample consultant lines with your own work. Quantity can be hours, days, units or 1 for a fixed fee. Add a tax rate if you are registered.
- Add payment details and terms. Choose the payment terms, add bank or payment-link details and your notes. A due date is calculated from the terms.
- Choose a look and export. Pick a template and colour, then download the PDF, print it, or save a PNG. Your work is saved in your browser as you type.
How consulting invoices differ
Consultants often bill large amounts to organisations with formal accounts-payable processes. That changes what makes an invoice good. The buyer’s finance team will check the invoice against a purchase order or a statement of work, so the document needs the right references, a clear breakdown, and exact terms. A consulting invoice also needs to separate fees from reimbursable expenses, because the two are often treated differently for tax and approval.
This template uses the Executive layout: a serif letterhead, centred title and double rules. It suits formal clients. If you prefer a more modern look, change the template in the Design panel without retyping anything.
What a consulting invoice should show
- Engagement reference: contract, statement of work or PO number, in the PO field.
- Billing period or dates of work, particularly for day-rate work.
- Fees by deliverable or by day, described so the approver can match them to the scope.
- Expenses itemised at cost, with receipts available on request, and clearly separated from fees.
- Tax: VAT, GST, HST or sales tax as appropriate for your location and your client’s.
- Payment terms matching the contract, for example Net 30, and the correct remittance details.
Consulting billing structures
| Structure | Typical invoice line | Watch for |
|---|---|---|
| Day rate | “Advisory days, 3–5 Nov” × days × rate | Define the length of a day (7 or 8 hours) in the contract |
| Fixed fee per milestone | “Milestone 2: diagnostic report” | Acceptance criteria and sign-off |
| Retainer | “Monthly advisory retainer (up to 10 hours)” | What happens to unused hours |
| Value or success fee | “Success fee per agreement” | Document the formula; verify with counsel |
| Time and materials | Hours by person and rate | Rate card agreed in advance |
Use the day rate calculator to convert a target income to a contractor rate.
Example consulting invoice
| Description | Qty | Rate | Amount |
|---|---|---|---|
| Strategy workshop (full day) | 2 | $1,200.00 | $2,400.00 |
| Follow-up advisory calls | 6 | $180.00 | $1,080.00 |
| Travel and expenses (at cost) | 1 | $214.50 | $214.50 |
| Subtotal | $3,694.50 | ||
| Tax at an illustrative 10% | $369.45 | ||
| Total | $4,063.95 | ||
Figures are examples only. Currency, tax rate and labels change in the editor to suit your country.
Expenses are billed at cost here; if you add a handling margin, state it in the contract.
Cross-border consulting and tax
Consultants often serve clients abroad. As a rule of thumb, services to a business customer in another country may be outside the scope of your local sales tax, or reverse-charged, but this depends on the place-of-supply rules of each country. In the EU, B2B services are generally reverse-charged with both VAT IDs on the invoice. In the UK, VAT rules for international services follow place-of-supply rules published by HMRC. In Australia, GST-free treatment applies to certain exports of services. Always check official guidance before invoicing a cross-border client, and ask your adviser if the amount is significant. See reverse charge explained.
Withholding taxes can also apply to cross-border fees. If a client deducts tax at source, show it as a separate line so your records reconcile.
Mistakes that delay consulting payments
- Leaving off the PO number or cost-centre code, so the invoice sits in a queue.
- Sending the invoice to the sponsor instead of the accounts-payable address.
- Combining fees and expenses in one line.
- Invoicing against a milestone the client has not signed off.
- Missing the client’s month-end cut-off, which adds weeks.
Getting paid faster as a consultant
Ask the sponsor for the correct invoice address and the payment-run schedule on day one. Put the payment terms in the statement of work and state a due date on each invoice. For long engagements bill monthly in arrears, or in advance for retainers. See deposits and milestone billing and payment terms explained.
Glossary
- SOW
- Statement of work: the document describing deliverables, schedule and fees.
- T&M
- Time and materials: billing by hours and expenses.
- Reverse charge
- The customer accounts for VAT or GST instead of the supplier.
- Registration thresholds (UK £90,000, Canada $30,000, Australia A$75,000, New Zealand NZ$60,000) change; confirm the current figure with your tax authority.
- Licence, certificate and payment-claim rules for trades differ by state, province and country. Check your regulator before relying on any note here.
Frequently asked questions
Should I bill expenses on the same invoice?
Usually yes, as separate lines, so approvers can match fees to the contract and expenses to receipts.
How do I show a PO number?
Use the PO field in the invoice details. It appears at the top of the document.
What is a typical consulting payment term?
Net 30 is common with larger organisations; smaller clients may agree to 14 days. Put it in the contract.
Can I charge a late fee?
If the contract allows it and local law permits. State the rate in the terms before the work begins.
How do I invoice a client in another country?
Check the place-of-supply and reverse-charge rules for your country and the client’s. The country generators include notes and links.
Should I invoice monthly or at milestones?
Follow the contract. Monthly invoicing smooths cash flow; milestone invoicing ties payment to results.
What if the client wants an itemised timesheet?
Use the timesheet to invoice tool to log hours and convert them into invoice lines.
Can I add my terms and conditions?
Yes, use the Terms field. It supports multiple lines.
