How to Invoice for Partial Payments and Show the Balance Due

Partial payments happen in two ways: planned (deposits, milestones, payment plans) and unplanned (a client pays part of an invoice and promises the rest later). Both are manageable if your invoices clearly show what's been paid and what's left.

The key lines

Any invoice with money already received should show:

Total	$5,000.00
Amount paid	−$2,000.00
Balance due	$3,000.00

In the generator, enter the amount already received in "Already paid (deposit)", and the invoice shows the total, the payment and the balance due automatically.

Planned partial payments

Deposit then final invoice

1. Deposit invoice (e.g. 40% on acceptance)
2. Final invoice for the full amount, showing the deposit as paid and the balance due

That's the approach most freelancers and small contractors use. See deposit invoices.

Milestone invoices

Each milestone gets its own invoice for that portion. The final one can list the earlier invoices for reference:

Milestone 3 of 3: launch. Previously invoiced: INV-0201 ($2,000, paid), INV-0214 ($2,000, paid).

Progress billing

In construction and long projects, each invoice bills the percentage completed since the last one, often with retainage held back. See progress billing.

Unplanned partial payments

A client pays $1,500 of a $3,000 invoice. What now?

1. Record the payment against the invoice in your log.
2. Send a receipt or acknowledgement for $1,500 so there's no confusion about what was received.
3. Confirm the remaining $1,500 and when it will be paid, in writing.
4. If the balance goes past the due date, send a reminder or statement showing the invoice, the payment and the balance. Don't reissue the original invoice with a different total.

If you've agreed a payment plan, write it down:

As agreed, the remaining $1,500 on INV-0188 will be paid in three instalments of $500 on 1 October, 1 November and 1 December.

Should you create a new invoice for the balance?

Usually not. The original invoice already represents the sale; creating another invoice for the balance can double-count revenue in your books and confuse the client. Instead:

• Send a statement showing the invoice, the payment and the balance, or
• Resend the invoice with the payment shown and the balance due highlighted (clearly labeled as an updated copy, with the same invoice number, and only if your accounting method allows)

The exception is a deposit invoice followed by a final invoice: those are separate invoices for separate portions of the sale, which is fine as long as the final one accounts for the deposit correctly.

Receipts for partial payments

For cash or cheque payments especially, give a receipt each time:

Received from Harbor & Pine Co.: $1,500.00 by bank transfer on 3 September 2026, part payment of INV-0188. Balance remaining: $1,500.00.

VAT and partial payments

In the UK and many VAT countries, receiving a payment can create a tax point. If you receive a deposit or part payment before issuing a VAT invoice, you may need to issue a VAT invoice for the amount received. Check with your accountant if you're VAT-registered.

Keeping it straight

A simple log (invoice number, total, payments received with dates, balance) prevents most partial payment confusion. If you have many customers paying in instalments, that's a good reason to look at invoicing software. See templates vs software.
