Invoice Template for Consultants

Your advice is worth paying for — your invoice should look like it. Speed Invoices gives consultants a free invoice template you complete online: type directly onto the invoice, add your logo, and download a clean PDF. There's no signup and no watermark, and your client data stays in your browser rather than on someone's server — which matters when the client names on your invoices are confidential.

Line items that make sense for consulting work

Consulting invoices live or die on clarity. A client-side finance team should be able to approve yours without asking questions. Common line items include:

• Advisory days — "Strategy workshop facilitation, 2 days @ day rate".
• Hourly engagements — "Stakeholder interviews and analysis, 14 hours".
• Deliverables — a fixed fee for a report, audit, or roadmap.
• Monthly retainer — "Advisory retainer, March" as a single recurring line.
• Expenses — travel, accommodation, or software passed through at cost.

Use the rich-text descriptions to reference the engagement letter or statement of work — "as per SOW #2, phase 1" gives procurement teams exactly the paper trail they want.

Day rates, retainers and milestones

Most consultants bill one of three ways: day rates invoiced monthly in arrears, a fixed monthly retainer for ongoing access, or milestone payments tied to phases of a project. Longer engagements often take a mobilisation payment up front. Whatever the model, keep one engagement per invoice — mixing two projects on one document is the fastest way to get it stuck in a client's approval queue.

Speed Invoices supports 46 currencies and 7 date formats, so invoicing a client in another country is just a dropdown, and tax and totals are calculated automatically.

The tip that shortens payment cycles

Ask for your client's PO number and accounts-payable email before you start work, and put both on every invoice. Large organisations don't pay invoices without a purchase order reference — and chasing one after the fact can add weeks to your payment cycle.

When the retainer becomes routine

If you invoice the same retainer every month, Pro ($5/mo) will do it for you: recurring invoices, scheduled sends, automatic payment reminders, and sending from your own domain so the email genuinely comes from your firm. If you delegate your admin, your assistant can prepare invoices in the same free editor — see the invoice template for virtual assistants they might use for their own billing.
