Fixed-Fee Invoice Template

Charge a single agreed price for a defined piece of work, with the scope stated plainly on the document.

How do I make a fixed-fee invoice?
In Receipt Caker, add one line describing the agreed deliverable and enter the flat price. The generator totals it, applies any tax you set, and shows the final amount to pay.
When is a fixed fee better than hourly billing?
A fixed fee works best when the scope is clear and agreed upfront. The client knows the exact cost in advance, and you are not tied to logging every hour, provided the work stays within the agreed boundaries.

What a fixed-fee invoice is

A fixed-fee invoice charges one agreed price for a defined scope of work, regardless of how many hours it actually took. The client agreed the number in advance, so there are no time-based calculations to explain.

It suits well-defined projects: a logo, a website page, a one-off report or a set deliverable. The clarity is the selling point — both sides know the exact figure before the work starts.

When to use a fixed fee

Use a fixed fee when you can describe the deliverable precisely and feel confident about the effort involved. It rewards efficiency, because faster work does not reduce your pay.

The trade-off is scope. If a client keeps requesting extras, those fall outside the agreed fee. A well-worded description on the invoice, matching your original quote, helps keep everyone aligned on what the price covers.

What to include on the invoice

State the deliverable clearly on the priced line, mirroring the language of your quote or agreement. A precise description reduces questions and makes approval quicker.

Add the invoice number, issue date and payment terms. If the fee is taxable, set the percentage so the tax and total appear at the foot of the document.

Building it in Receipt Caker

Add one line with the agreed price, or split the fee into a few descriptive sub-lines if you want the client to see how it breaks down. Either way, the generator totals everything for you.

Preview the wording, then export a free watermarked PNG or upgrade to Pro for a clean PDF and your logo. Receipt Caker builds the document only; it does not process the payment or send the invoice on your behalf.

Frequently asked questions

Should a fixed-fee invoice show hours?
No, and that is the point of the model. A fixed-fee invoice states one agreed price for the deliverable rather than a breakdown of time. If you want the client to see components, split the fee into descriptive sub-lines by phase or deliverable, but keep them as amounts rather than hourly calculations.
How do I handle extra work beyond the fixed fee?
Bill it separately. Add a new line, or issue a second invoice, describing the additional work and its own price, agreed with the client first. Keeping extras off the original fixed line preserves the meaning of the agreed fee and shows clearly that the added cost was a distinct request.
Can I break a fixed fee into parts on the invoice?
Yes. You can list several descriptive lines, such as planning, build and handover, each with its own amount, that add up to the agreed total. This gives the client visibility without turning the invoice into an hourly document. The generator adds every line to reach the same final figure either way.
Do I need a deposit with a fixed-fee invoice?
That depends on your arrangement. Many people take a deposit upfront and invoice the balance on delivery. If you do, raise a separate deposit invoice first, then show the remaining balance on the final fixed-fee invoice. Receipt Caker can produce each document, but does not track which parts have been paid.
How is a fixed fee different from an estimate?
An estimate proposes a likely price before you commit; a fixed-fee invoice charges the agreed price after both sides confirm the scope. An estimate can change, whereas the fixed fee is the settled figure. Use an estimate to win the work, then convert the agreed number into a fixed-fee invoice to bill it.
Can I add tax to a fixed fee?
Yes. Set your tax percentage in the generator and it applies to the fixed amount, with the tax and grand total shown at the bottom. If the work is not taxable in your situation, leave the rate at zero and the document will simply show the agreed fee as the amount due.
