How to write a web design invoice
Last updated
To write a web design invoice, you confirm the stage is done, bill the amount the proposal set for it, send it with a short note, and follow it until it's paid. The invoice itself is the easy part. The steps around it help you get paid on time.
How do you write a web design invoice?
You write it from the agreed work in the proposal or quote. Each step below turns a finished stage into a paid bill.
| Step | What to do | Why it matters |
|---|---|---|
| Confirm the stage is done | Get the client's sign-off on the stage you're billing | It's harder to argue over work the client has approved |
| Find the agreed amount | Open the proposal or quote and find the price for that stage | The bill matches what the client signed |
| Fill in the invoice | Use your template: numbers, dates, line items and the total | Every bill looks the same, so nothing is missed |
| Write the lines plainly | Name the stage and what it covered, in words the client uses | The person who pays can tell what it's for |
| Send it to the right person | Send it to whoever approves bills, with a short note | It doesn't sit in the wrong inbox |
| Log it | Record the number, the amount and the due date | You know what's open at a glance |
| Follow up | Send a polite reminder when the due date passes | A reminder keeps the bill in front of the client |
| Mark it paid | Record the payment and send a receipt if the client wants one | Your books match your bank |
Keep the note that goes with the bill short. Say what stage it covers, the amount, the due date and how to pay. If the next stage starts once this one is paid, say that too. For the fields on the invoice, see the web design invoice template.

How do you invoice a monthly website payment?
You invoice a monthly website payment the same way each month: the same day, the same lines, and a note on anything that changed. A client who pays monthly should be able to read the bill in seconds.
- Pick one billing day. Bill on the same day each month, so the client can plan for it.
- Name the plan on the bill. Write what the monthly fee covers, such as hosting, updates or a set amount of changes.
- Bill extras on their own line. Work outside the plan gets its own line, with a short note on what it was.
- Say what period it covers. Write the month the bill pays for, so nobody confuses it with the last one.
- Set up repeat billing if you can. Check whether your invoicing tool can send the same bill each month, and whether it can take the payment too.
- Check it every month anyway. Make sure the lines still match what the client gets.
Ask the client one question when the plan starts: who should get the bill each month? It saves a missed payment later. For what a monthly plan bundles, see how website as a service works.
A steady bill needs steady work behind it, and DeskTeam360 offers a short, no-commitment call on who builds your client sites.
