A remainder needs identification
A confirmed USD 1,700 receipt split USD 1,000 and USD 500 leaves USD 200 unallocated. Keep that amount assigned for clarification rather than silently reducing another invoice.
Payment reconciliation
Free Receipt Allocation Checker
One client transfer can cover several invoices. Check the proposed split against the confirmed gross receipt before posting it, while keeping each invoice's open balance and the client's instructions available separately.
What you can do here
Check whether three proposed invoice allocations fit within one confirmed receipt, showing any unallocated remainder or excess allocation.
Built for real invoice workflows
Save the reviewed split against the confirmed receipt before updating invoice payment status.

Calculation notes
How the result is calculated
Allocated = sum of three proposed invoice allocations. Unallocated remainder = max(0, receipt − allocated). Excess allocation = max(0, allocated − receipt). Use one confirmed gross receipt and one currency; a processor's net payout or a client's remittance notice is not automatically the confirmed invoice receipt. Check invoice-specific balances separately.

An impossible split
USD 1,000 received with proposed allocations USD 700 and USD 400 exceeds the receipt by USD 100. Revisit the instructions and the receipt; the calculator does not create more cash.
Questions about this calculation
Does this check every invoice's open balance?
No. It checks the receipt-side sum. Verify each invoice's existing balance, prior allocations and approved adjustments before posting.
Is remittance advice a confirmed receipt?
No. It explains the payer's intended split. Check the received transaction through the appropriate bank or payment evidence before reducing balances.
How to use it
1
Enter one confirmed receipt in the invoice currency.
2
Enter up to three proposed allocations; use zero for unused rows.
3
Resolve a remainder or excess and check each invoice balance before posting.
Why it helps
Prevent allocating the same receipt beyond its amount.
Expose unallocated money without treating it as an invoice credit.
