Invoice Template for Consultants
Whether you bill by the hour, by the day, or on a monthly retainer, you need an invoice that looks like you charge what you charge. Fill this one in online, add your logo, and download a clean PDF — no signup, no email wall.
Built for how consultants actually bill
Most invoice templates assume you sell a thing. You sell time, judgment, and outcomes — and you probably bill the same client three different ways depending on the engagement. Here's how to make each one read cleanly to the person who actually cuts the check.
Hourly
Hours × rate, dropped straight onto a line item.
Bill discovery calls, working sessions, and async review by the hour. List the date or work package on each line so the client can see exactly what they paid for — that's what stops the "what was this for?" email.
Day rate
One line, one day, one number.
Strategy days, workshops, and on-site engagements are cleaner as a day rate than a wall of hours. One line item — "2 × strategy day @ $1,200" — reads better and is easier to approve.
Monthly retainer
Same amount, same date, every month.
A retainer should be the most boring invoice you send: identical number, predictable date. Note the retainer period (e.g. "Advisory retainer — March") so it threads cleanly into the client's books.
Project / milestone
Bill the deliverable, not the clock.
Fixed-scope work bills against milestones — "50% on kickoff, 50% on delivery." Reference the SOW or proposal on the invoice so there's a clean paper trail from quote to payment.

What to put on a consultant's invoice
Corporate clients pay invoices through an accounts-payable process, not out of goodwill. Give that process everything it needs the first time and you skip a week of back-and-forth. Here's the checklist:
- Your details. Business name, address, and ABN/EIN/VAT number if you have one. Sole-trader consultants: your legal name is fine.
- Client details. The legal entity you contracted with — and the right billing contact. Big clients route invoices through AP, not your day-to-day champion.
- Invoice number. A unique, sequential ID (INV-001, INV-002…). Their accounts team needs it to match payment to invoice.
- PO or engagement reference. If the client issued a purchase order or has an SOW number, put it on the invoice. No PO on a corporate invoice is the #1 reason it sits unpaid.
- Itemized work. Each line = what you did, the rate or basis (hourly / daily / retainer / milestone), and the amount. Specific beats vague every time.
- Dates and terms. Issue date, due date, and your payment terms (Net 14 / Net 30). State terms explicitly — don't assume.
- How to pay. Bank/wire details, or a "Pay now" link. The fewer steps between reading and paying, the faster you get paid.

Consultant invoicing questions, answered
How should I invoice for a monthly retainer?
Keep it identical and predictable. One line item naming the retainer and the period ("Advisory retainer — March 2026"), the agreed amount, and the same due date each month. Consistency is what keeps a retainer off the client's "let me check this one" pile. Fee-Lion can set this to recur automatically so you never have to remember.
Hourly or day rate on the invoice?
Bill the way you agreed in the SOW. If you sold hours, list hours × rate with the work package on each line. If you sold days, one line per day reads cleaner and is easier to approve. The rule of thumb: fewer, clearer line items get paid faster.
Do I need a PO number?
For most mid-size and enterprise clients, yes — and a missing PO is the single most common reason a consultant's invoice stalls in accounts payable. Ask for the PO before you start the work, and put it on every invoice for that engagement.
What payment terms should I set?
Net 14 or Net 30 are standard for consulting. State the terms on the invoice — don't assume. If you work with slow-paying enterprises, the trick isn't shorter terms, it's consistent follow-up. (That's the part Fee-Lion does for you.)
Can I send an estimate or quote first?
You should — scoped work goes smoother when the client approves a number up front. Use the free estimate generator, and when they say yes, Fee-Lion turns that estimate into an invoice in one click.
