When a client pays an invoice, you record the payment against it. FreelancerFlow supports as many payments as you want per invoice, which makes partial payments and milestone billing straightforward.

Goal: by the end of this you'll have recorded one payment on an invoice and understand how the remaining balance is calculated.

Prerequisites

An invoice in any status except Cancelled. See Creating an invoice from scratch.

Step 1: Open the invoice

From the project detail or the Money tab, tap into the invoice. The detail screen shows the line items, totals, and a Payments section at the bottom.

Step 2: Tap Add payment

The button sits in the Payments section header. The Add payment sheet opens.

Step 3: Fill in the payment

Amount (required) — how much the client paid. Pre-fills with the remaining balance so you can quickly accept a full payment.
Method — Bank transfer, Cash, Crypto, or Other. Used for reporting on the Money tab; doesn't affect totals.
Paid at — date the payment landed. Defaults to today.
Notes (optional) — anything you want to remember (transaction ID, reference number).

Tap Save.

How the remaining balance works

Remaining balance = Total − sum of all payments, floored at zero.

Each payment is its own row. You can:

Add as many as you need until the remaining balance hits zero.
Edit any payment (tap the row → Edit).
Delete a payment (swipe left → Delete) — the remaining balance is recomputed instantly.

Once the remaining balance hits zero, the invoice's status flips to Paid automatically.

Partial payment example

Invoice total: 5,000 EUR.

Payment 1: 1,000 EUR deposit on 1 March → remaining 4,000 EUR → status stays Sent.
Payment 2: 2,000 EUR milestone on 1 May → remaining 2,000 EUR → status stays Sent.
Payment 3: 2,000 EUR final on 1 June → remaining 0 → status flips to Paid.

The Money tab's Earned KPI reflects each payment on its paid-at date, so cash flow across periods is captured even on a single invoice.

Recording an overpayment

The app does not accept an amount that exceeds the remaining balance — the Save button stays disabled. If a client overpaid, record the invoice amount, then handle the surplus outside the app (refund or apply manually to the next invoice).

Troubleshooting

Status didn't flip to Paid. The remaining balance is still non-zero. Pull up the payments list and check for missing rows or wrong amounts.
Wrong date. Edit the payment, change Paid at. The Money tab re-aggregates immediately.
Multi-currency client. Each payment is in the invoice's currency. If a client paid you in a different currency, record the converted amount and put the originals in the notes.
