Start with the specific disagreement
A missing deposit or credit can make an invoice appear more contentious than it is. Rebuild the balance using the original charge, every recorded payment and each agreed adjustment. The aim is to produce one total that both parties can follow. Keep a credit note separate from a payment: one changes the charge, while the other records money already received.
Work through the facts, one step at a time
Match the earlier transaction
Find the amount, date, payer name and reference. Check whether the deposit was allocated to a different invoice or project stage. Where several people pay, a name mismatch may explain why an entry was not recognized.
Write out the reconciliation
Start with the invoiced total, subtract recognized credits and payments, and show the remaining balance. Avoid subtracting the same deposit twice if it already appears as a credit line or payment allocation.
Ask for a corrected statement
Send only the relevant payment evidence and ask the business to confirm the allocation. Request a revised invoice or account statement that clearly references the earlier document so both sides retain an understandable audit trail.
What this can look like
A $2,000 invoice already includes a $100 discount but omits a $500 deposit. The remaining balance is $1,500, not $1,400. Treating the discount as a new deduction would introduce another error while correcting the first.
This is an invented scenario to explain the approach, not a customer result or a prediction of your outcome.
Records worth gathering
- Original invoice
- Deposit receipt or payment reference
- Credit notes
- Account statement
Keep originals and prepare copies of the relevant parts. Redact unrelated personal details before sharing. Explain any gaps in the record rather than filling them with assumptions.
Open a clearer conversation
Edits stay on this page and are lost when you leave. Nothing is sent automatically. This is a discussion starter, not a legal notice or settlement agreement.
Before you agree to the next step
Redact unrelated transactions and account details from payment evidence. Confirm changed payment instructions through a known channel rather than trusting a new bank detail in an email.
Put any proposed outcome into specific terms: who will act, what they will do, the amount if money is involved, and the date. Identify what remains unresolved. An invitation, a discussion and a signed agreement are different stages.
Should the business delete the old invoice?
Ask for a clear correction process and references between documents. Recordkeeping requirements vary, so the important practical point is that both sides can identify the current balance and how it was calculated.

A private place to prepare your side
SettleBetween provides private AI guidance for each person and a shared space to discuss approved information. You choose what to share and whether to agree. Availability depends on both parties’ locations and the dispute type.
Free to start. The case starter pays $79 only after both parties sign. The invited party never pays the agreement fee. See included access and pricing.
