INVOICE GUIDES
Deposit and Final Invoices: Avoid Charging the Same Work Twice
A deposit invoice requests an advance payment. It does not prove that the advance arrived. Before preparing a final invoice, separate three figures: the project price, amounts already invoiced, and payments actually received. They answer different questions and should not be substituted for each other.
The ToolNivo Invoice Generator can present a manually prepared invoice and an amount-paid total. It does not connect deposit and final documents, check your bank account or maintain a project ledger. The reconciliation must happen in your own records.
Choose one billing method before the first request
There are two useful presentation patterns. Under a full-value approach, one invoice bills the complete agreed supply and later payment records show how much remains. Under a staged approach, separate invoices bill distinct portions of the project. Which documents are appropriate, and when tax becomes due, depend on your agreement and applicable accounting rules.
Do not combine the patterns accidentally. If a deposit has already been issued as a separate sales invoice, a second invoice for the full project can duplicate billed revenue unless your accounting process handles the adjustment correctly. Ask your bookkeeper how the final document should reference the earlier one before creating it.
Worked example: one invoice, two payments
Assume an illustrative project total of USD 2,400 with no tax, discount or shipping in the example. The parties agree to pay USD 600 first and USD 1,800 after completion. If your approved process uses one full-value invoice, its initial amount paid is zero and its total remains USD 2,400. The payment schedule explains when each part is due.
Once USD 600 is received and allocated to that invoice, a balance copy can show total USD 2,400, amount paid USD 600 and balance USD 1,800. Keep the original issued copy and the payment record. A promised transfer is not a received payment. After the remaining USD 1,800 clears, the cumulative amount paid becomes USD 2,400.
Worked example: separately billed stages
Suppose instead your approved process bills a USD 600 first stage and a USD 1,800 final stage. The second invoice contains only the second stage, with a note referencing the first invoice. Its amount-paid field starts at zero unless money has already been allocated specifically to it. Entering the earlier USD 600 again would incorrectly reduce the second balance to USD 1,200.
Use a separate project summary to show combined billed amounts of USD 2,400. A final invoice and a project statement are not interchangeable. If the client requires a cumulative document, use a system that supports the required reconciliation rather than disguising the earlier invoice as a discount.
Prepare the final handover check
- Confirm the final approved scope, including additions and cancellations.
- List every earlier invoice by number and amount.
- Match each received payment to the invoice it settles.
- Resolve refunds or credits in the correct accounting document.
- Check that the new bill contains only the intended remaining charge.
- Explain the project reference and payment history without claiming an unpaid deposit was received.
Keep a separate invoice register so a browser refresh cannot erase the project history. For stage acceptance, use the milestone invoicing checklist.
Review the ToolNivo PDF before sending
Describe the billed stage in the line item, enter the actual amount charged on this document, and use notes for the project reference. ToolNivo has no negative adjustment lines or dedicated deposit reconciliation. Its discount field reduces the price; it is not a payment field. Download the PDF, open it, and read the total and balance as a customer would.
Save the PDF together with the approval and payment allocation outside the tool. When a deposit changes the tax point or needs a specialist advance-payment document, obtain the appropriate document through your accounting workflow.
Frequently asked questions
Should I enter an unpaid deposit as amount paid?
No. Amount paid should reflect a payment actually received and allocated to that invoice, not a requested advance.
Can a deposit be deducted as a discount?
A payment and a price reduction have different meanings. Use the correct payment allocation or accounting adjustment instead of disguising a deposit as a discount.
Does ToolNivo link deposit invoices automatically?
No. It creates individual PDFs from manual entries. Keep the relationship between documents in your own records.
