Cash application is the process of matching a bank transaction to the invoices it pays. Upflow’s matching interface lets you work through your unapplied transactions one by one, link each one to a customer, select the relevant invoices, and apply the payment — all in a single modal.

​
Open the matching interface

From the Bank transactions page, click the blue Apply button in the top-right corner to open the matching interface for all unapplied transactions in the selected bank account. The Bank transactions list showing the blue Apply button in the top right, with a list of unapplied transactions sorted by posted date. The matching interface opens as a modal with two panels:
  • Left panel — the list of all unapplied transactions for this bank account, sorted by posted date (newest first). Use the search bar or the sort dropdown to navigate.
  • Right panel — the matching workspace for the currently selected transaction.
The matching interface modal showing the left panel with the transaction list and the right panel with transaction details, customer selector, and invoice table. The left panel shows the total unapplied amount and currency for the bank account at the top. Clicking a transaction in the list loads it in the right panel.
👉 You can also open the matching interface for a single transaction by clicking the small Apply button on that row in the list. This opens the same modal without the left-hand transaction list.

​
Match a transaction

​
Step 1 — Review the transaction details

At the top of the right panel, you can see the transaction’s date and description as provided by your bank feed. These are the clean, human-readable fields from your bank provider.

​
Step 2 — Select a customer

Use the customer dropdown to link the transaction to a customer. Start typing to search across all your customers. The customer dropdown open with a search field, showing filtered results matching the typed name. Once you select a customer, the invoice table loads with their outstanding invoices. The interface switches to the Suggested tab if a match was automatically proposed. The matching interface after selecting a customer, showing the Suggested tab with one proposed invoice match and a Match customer only button in the footer.
👉 If you want to link the transaction to a customer but not apply it to any invoice yet, click Match customer only at the bottom of the modal. The transaction will be synced to your accounting system as an unapplied customer payment.

​
Step 3 — Select invoices

Switch between tabs to find the invoices you want to apply:
  • Invoices — all outstanding invoices for the selected customer, with search and filter options
  • Selected — invoices you have already selected in this session
  • Suggested — invoices automatically proposed by Upflow based on the transaction amount and customer
The Invoices tab showing all outstanding invoices for the customer, with filters applied for customer, status and currency. One invoice is checked and has an amount entered. To apply an amount to an invoice:
  1. Click the → arrow button on an invoice row to automatically fill in the outstanding amount.
  2. Or type a custom amount directly in the Amount to apply field.
The footer shows a running total: amount selected / remaining to apply, so you always know how much of the transaction is still unallocated.

​
Step 4 — Apply

Once you have selected your invoices and entered amounts, click the apply button in the footer:
  • Apply fully — when the selected amount equals the full transaction amount (€0.00 remaining)
  • Apply partially — when the selected amount is less than the full transaction amount
  • Match customer only — when no invoices are selected but a customer is linked
The matching interface footer showing the Apply fully button enabled, with €38,153.23 selected and €0.00 remaining to apply. After clicking, Upflow applies the transaction and automatically moves to the next unapplied transaction in the left panel list.

​
Exclude a transaction

If a transaction is not relevant to accounts receivable (for example, a payroll transaction or an accounts payable payment), click Exclude at the bottom of the left panel. Excluded transactions are hidden from the unapplied list and will not be synced to your accounting system.

​
Transaction statuses

StatusMeaning
UnappliedThe transaction has not been applied to any invoice. Applied amount = €0.
AppliedThe transaction has been fully applied. Applied amount = transaction amount.
ExcludedThe transaction has been marked as irrelevant to accounts receivable.
A transaction must be linked to a customer before it can be synced to your accounting system as a customer payment. If no customer is linked, the transaction will not be synced.

​
Edit an applied transaction

To update a transaction that has already been applied, click the Apply button on that row in the bank transactions list. The matching interface opens in edit mode, defaulting to the Selected tab showing the invoices that were applied. You can change the applied amounts, add or remove invoices, or change the customer. When you click Update, a confirmation modal will appear describing the impact on your accounting system before the change is saved.
