How to fill out this consultant invoice template

  2. Add your name or firm name and contact details, then the client’s company, billing contact and any PO or engagement number they need. Give the invoice a unique number.
  3. Bill the way your engagement letter sets it up: hours at your hourly rate for strategy sessions and analysis, a flat monthly retainer, or a fixed project fee. Say what the retainer covers, such as up to 10 hours of advisory, and put extra hours on their own line.
  4. Add workshops and training as separate lines, and list travel at cost with receipts attached. Set the due date, such as Net 30, and ask the client to reference the invoice number with their payment.
  5. Send it as a PDF, or as a payment link with Onigiri so your client can pay by card.

Invoice checklist

What consultants should include on an invoice

What consultants should include on an invoice

A consulting invoice is the bill a consultant sends a client for advice, analysis, training or other expert work, based on the terms of the engagement. Corporate clients often route invoices through accounts payable, so clear details help yours get approved and paid on time.

  1. Your details. Your name or firm name, address and email, plus your EIN if the client asks for a tax ID.
  2. Your client. The client’s company name, billing contact or accounts payable email, and any PO or engagement number they require.
  3. Number and dates. A unique invoice number, the issue date, the due date and the period or project the invoice covers.
  4. Line items. Hours with your rate and a short note on the work, the retainer with its period and what it includes, and workshops or deliverables as separate lines.
  5. Expenses. Travel, lodging and other costs you pass on at cost, with receipts attached if your contract asks for them.
  6. Payment terms. The due date, such as Net 30, how to pay you, and a request to reference the invoice number with the payment.
  7. Late fee. Your late fee or interest policy, if your engagement letter includes one.

Getting paid

Billing tips for consultants

Billing tips for consultants

Set your rates and terms in the engagement letter, then repeat them on every invoice.

  • Net 30

    Payment terms

    Net 30 is common for corporate clients in the US, and larger companies may ask for longer terms. For smaller clients, Net 15 or due on receipt keeps cash moving. Write the exact due date on the invoice, not just “Net 30”.

  • 25–50%

    Retainers and deposits

    Bill a monthly retainer at the start of each period, so you’re paid before the hours are used. For fixed-fee projects, ask new clients for 25–50% upfront and deduct it on the final invoice.

  • When to send the invoice

    Send retainer invoices at the start of each month and hourly invoices at the end of each month or engagement. On longer projects, invoice at each milestone. The billable hours calculator helps you total your hours.

  • Late payments

    Corporate invoices often stall in approval, so ask upfront who receives them and whether they need a PO number. Send a reminder the day after the due date, and if your contract allows it, add a late fee as a separate line; the late fee calculator works out the amount.

  • Taxes

    Consulting is usually not subject to sales tax, but some states tax certain services, so check your state’s rules. Clients may ask for a Form W-9 and may send you a Form 1099-NEC, and the self-employment tax calculator estimates how much of each payment to set aside. This is general information, not tax advice.
