Illustrative example
Two valid structures must not be combined
- Whole-project reconciliation
- USD 8,000 less USD 2,000 received advance = USD 6,000
- Installment structure
- USD 2,000 already billed; USD 6,000 still unbilled
- Incorrect double deduction
- USD 6,000 remainder less another USD 2,000
- Evidence required
- Receipt and prior allocation status
Illustrative before-tax arithmetic. Choose the document structure appropriate to the actual records.
See the recorded product workflowDecisions to make before billing
A final invoice should make the project charge and the earlier advance easy to reconcile. The key check is whether the deposit was actually received and whether it has already been applied. A requested but unpaid deposit is not money available to reduce the final balance.
Before drafting, decide how the deposit was recorded. An advance held for later allocation differs from a first installment already invoiced and settled. If the earlier installment is already part of the billed project total, do not subtract it again from another invoice for only the remaining work.
The example uses a USD 8,000 project with a USD 2,000 received advance and no other charges. A full-project reconciliation leaves USD 6,000 before separately required tax treatment. Use your billing system's supported allocation and document process; this guide does not assume InvoiceAgent automatically allocates advances.

Outcome
Use this page to move from general research into a calmer, more repeatable invoicing process.
Work through the billing decision
Verify the advance evidence
Find the deposit document, confirmed receipt, currency, and project reference. Check for an existing allocation, refund, or other use. Resolve a missing or mismatched receipt before deducting it.
Reconcile the final scope
Start with the agreed project subtotal and approved changes. Separate tax treatment and any credits. Determine whether the final document bills the whole project with an advance allocation or only previously unbilled work.
Show one allocation and the remaining due
Use the supported document method and label the received advance with its amount and reference. Check that the project, invoice, and payment records all agree. Preserve the audit trail rather than overwriting the earlier deposit request.

Avoid this
Deducting a paid milestone twice
If the first USD 2,000 was already a billed installment, an invoice for the USD 6,000 unbilled remainder must not subtract another USD 2,000 simply because it was called a deposit.
Avoid this
Using a negative line without checking treatment
A negative service line, payment allocation, and credit note are different records. Use the appropriate method for your billing system and transaction.

Questions people usually have before changing the workflow.
What if the deposit is still unpaid?
Do not treat it as a confirmed receipt. Review the project agreement and outstanding request before determining the final amount and document structure.
What if approved extras increase the project price?
Include the approved change references in the reconciliation, then apply the received advance once against the appropriate record.
Does applying a deposit change tax?
The correct treatment depends on the transaction and local rules. Confirm tax timing and document requirements separately rather than inferring them from this arithmetic example.
