A customer pays before you finish a project. The money is in the bank, but the accounting question is not answered by the deposit alone. What does the payment cover, and what obligations remain?
Businesses use words such as deposit, retainer and prepayment differently. Your accountant needs the actual arrangement, not just the label, to evaluate the accounting and tax treatment.
Keep the agreement with the payment
Provide the contract or written terms showing what the customer purchased, when work is expected and whether the payment can be refunded. Identify any conditions that allow the business to keep the amount or apply it to later invoices.
If the agreement changes, retain the change with the original records. A later cancellation, revised scope or credit may explain why the amount remaining on the books differs from the original payment.
Distinguish different reasons for receiving money
A refundable security deposit is not necessarily the same arrangement as an advance payment for services. A payment applied to an outstanding invoice raises a different question again. Explain which situation occurred rather than placing every early receipt in one category.
Do not assume that unfinished work automatically means the receipt is excluded from taxable income. Accounting method and the applicable rules matter. Your accountant should review the facts before reaching a conclusion.
Connect the deposit to the later invoice
In an illustration, a customer pays $600 toward a $2,000 project. When the final invoice is issued, it should be clear whether the $600 has already been applied and what amount remains payable. If both the early receipt and a later payment import are treated as unrelated sales, the records may overstate activity.
With no changes, refunds or additional charges, the customer would still owe $1,400. A useful customer statement shows the $2,000 charge, the $600 already received and that remaining amount. This gives the owner a clear collection figure even while the accountant evaluates the appropriate revenue timing.
Keep the invoice reference, payment date and application detail together. The example explains the workflow; it does not prescribe the tax timing or journal entries for every business.
Review the outstanding list
For each open customer amount, record the original payment, amounts applied, refunds and remaining balance. Identify work that has been completed and canceled projects that still have unresolved balances.
A longstanding balance may be legitimate, or it may show that the final invoice was never connected. Investigate before clearing it as income, expense or an unexplained adjustment.
Make customer communication match the records
The invoice or statement sent to the customer should make the applied amount understandable. If your internal records show a remaining credit while the customer believes everything was settled, resolve the underlying facts before sending another bill.
Also explain who can authorize refunds and how they are recorded. A processor refund and an accounting credit should be connected so they do not become two unrelated reductions.
