Banking and reconciliation
Understand bank account connections, open banking, bank statements, transaction review, and document matching.
The Banking section shows bank accounts, transactions, and whether each transaction has the document or explanation your accountant needs.

Banking helps Numonis and your accountant match transactions with invoices, receipts, and supporting documents. The Balance card shows the account balance, and the notice lists the missing statements.
What open banking means
When Numonis says connect a bank account, it means creating an open banking connection. You authorize a regulated provider to read transaction information from your bank so the Numonis platform can show movements and help reconciliation.
The connection is read-only in the Numonis platform. It is used to import transactions and balances; it does not allow Numonis to move money from your bank account.
What you can do in Banking
- Connect a bank account through open banking.
- Upload bank statements periodically when a bank account cannot be connected. Their transactions appear right after processing, and your accountant still reviews each statement. If Numonis finds a problem, the statement shows a warning icon in Documents, and its transactions appear after your accountant approves it.
- See which months still need a bank statement.
- Review transactions and missing documents.
- Link an existing document to a transaction.
- Upload a document directly from the transaction detail.
- Refresh or reconnect an expired bank connection.
Missing bank statements
For accounts maintained through statement uploads, the notice lists missing statements for closed months in the current fiscal year, starting in January. If your collaboration with Numonis began later, it starts from that month. It also starts from the month of the account's first uploaded statement, so earlier months — before that account had any statement — are not requested. The current month and previous years are excluded.
Each account shows its three most recent missing months. Hover over +N, or focus it with the keyboard, to see the full list. On a phone or tablet, tap +N. Upload the missing statements from Documents; statements awaiting your accountant's review already count as received.
Common questions
Should I connect my personal bank account?
Connect bank accounts used for business activity. If a personal bank account includes business transactions, discuss it with your accountant before connecting it.
Can I connect a credit card?
Some credit cards can appear as bank accounts if the bank/provider exposes them. If the card cannot be connected, upload statements periodically so your accountant can review the transactions.
Is open banking safe?
Open banking access is based on consent and regulated payment-service providers. The Numonis platform uses Kontomatik for bank connections, and Kontomatik is listed as an account information service provider. The European Banking Authority maintains PSD2 registers for authorized or registered providers.
