The app ships, the build looks fine in a test install, and then release week turns into a scramble of crashes, login edge cases, and last minute store feedback. An app development invoice puts the money part in writing at the same level of clarity as the build work, so the client can see what’s being billed and what has to clear before handover and final submission steps.

The invoice keeps the structure tight: Line items holds the work being billed (the template’s single item is only a placeholder), and Payment is due on the date spells out when payment has to land and what slips if it doesn’t. The totals sit underneath, and the wording ties final payment to code handover and the last submission push, so the client doesn’t read the invoice as “pay whenever.” A brass accent with Poppins headings over Inter body text keeps the page feeling engineered and procedural, not like a generic billing sheet.

  • Line items Swap the placeholder entry for the work you’re billing for this stage of the app build, with your own prices.
  • Payment is due on the date States that payment is due on the date shown and links late payment to delayed delivery and store submissions.
  • Totals Shows the amount due as a totals block under the line items so the client can see what the invoice adds up to.

Once the invoice is in your workspace, you replace the placeholder line with your own lines and prices, then send it to the client. If you’ve connected a payment method, the same invoice can be paid online, leaving you with a record of what was billed and what was paid.

What to include in an app development invoice

PartWhat it covers

Line items

The Line items section holds the work you’re billing for; the single starter item is a placeholder, so you replace it with your own lines and prices before sending.

Payment is due on the date

The Payment is due on the date section carries the Totals block and the payment terms, including when code handover and final submission steps start and what delays if payment is late.

Questions about this invoice template

What should an app development invoice include?

An app development invoice usually includes the billed line items, the total due, and the payment terms. This one also ties final payment to code handover and final submission steps, so the release work doesn’t float without payment.

When should I send an invoice for mobile app development work?

An invoice goes out when a billable milestone or delivery point is reached and payment needs to be collected. This template’s payment terms are written around the date shown on the invoice and what happens after payment clears.

How do I describe app development work on invoice line items?

Line items work best when they name a specific deliverable or milestone rather than a vague “development.” The placeholder line in this template is only a starting point, so you’ll want to rewrite it in your own project’s terms and price it accordingly.

Can an invoice hold delivery until the final payment clears?

An invoice can state that handover and final submission steps begin once payment has cleared. This template includes that wording, and it also notes that late payment can delay delivery and store submissions.

What happens if a client pays late on a software development invoice?

Late payment usually pushes delivery timelines, especially around release work that depends on coordination and approvals. The payment terms in this invoice say that delivery and store submissions may be delayed if payment is late.

Should an invoice cover who owns the source code or the app store accounts?

Ownership terms normally belong in a contract, not in an invoice, because an invoice is a bill rather than the full agreement. If ownership needs to be spelled out, the invoice can stay focused on payment while the contract covers IP and account control.
