How to sync Komerční banka transactions to YNAB

Komerční banka is one of the most searched banks among European YNAB users in Czechia. The budgeting method works — but keeping accounts current when your bank and YNAB do not talk to each other creates weekly friction.

YNAB does not offer Direct Import in Czechia at all. If you bank with Komerční banka and use YNAB, the default workflow is still manual: log into Komerční banka, download a CSV or OFX export, upload it to YNAB, and reconcile duplicates by hand.

Even when imports work, the process is fragile: export formats change, pending transactions appear twice, and your YNAB budget is only as fresh as your last upload. If you share a budget with a partner or track multiple Komerční banka accounts, the manual work multiplies.

BudgetSyncer is built for European YNAB users who want automatic bank sync without storing bank passwords. You connect YNAB once with OAuth, then authorize Komerční banka through regulated PSD2 open banking (via GoCardless). BudgetSyncer reads transactions and imports them into the YNAB accounts you choose.

Your Komerční banka login never passes through BudgetSyncer — authentication happens on your bank’s own secure consent screen, the same flow used by other open-banking apps in Czechia. Access is read-only: BudgetSyncer cannot move money or change account settings.

Transactions sync on a schedule (several times per day). YNAB handles duplicate detection when transactions arrive — BudgetSyncer focuses on keeping the feed from Komerční banka reliable, including notifications when bank consent needs renewal.

Step 1 — Create a free BudgetSyncer account and sign in. You can browse supported banks and connect YNAB before subscribing. No credit card is required to explore whether Komerční banka appears for Czechia in the bank directory.

Step 2 — Connect YNAB with OAuth. BudgetSyncer requests permission to read your budgets and accounts and to create transactions in the YNAB accounts you select. You can revoke access anytime from YNAB or BudgetSyncer.

Step 3 — Add a bank connection and select Czechia in the country picker. Search for Komerční banka. If your branch or subsidiary appears under a slightly different name, pick the listing that matches your account — open banking directories sometimes use legal entity names.

Step 4 — Complete Komerční banka’s authorization flow in your browser. Your bank may ask you to confirm access in its mobile app or with strong authentication. Once approved, BudgetSyncer can read new transactions from the linked account.

Step 5 — Map the Komerční banka account to the correct YNAB account and enable sync when you subscribe. New transactions flow into YNAB automatically. Review imports in YNAB as you normally would; categorization and reconciliation stay in YNAB.

Bank connections run through GoCardless Bank Account Data, a PSD2-regulated provider. BudgetSyncer does not store your Komerční banka credentials. Consent expires under EU rules — when it does, you re-authorize through a short in-app flow.

You can disconnect Komerční banka from BudgetSyncer or revoke consent directly at your bank. We store only OAuth tokens and mapping settings needed to sync while your subscription is active, as described in our privacy policy.

Most users complete setup in under five minutes. After the first sync, check YNAB for imported transactions from Komerční banka and confirm payee names look right. You can adjust field mapping in BudgetSyncer if you want cleaner memos or payees.

Running a shared YNAB budget? Each linked Komerční banka account counts as one connection — map checking and savings separately if you track them in different YNAB accounts. Cancel anytime from account settings; bank consent can also be revoked at Komerční banka directly.

If Komerční banka is not listed for Czechia, use the unsupported-bank form on this page — we track demand and expand coverage as GoCardless adds institutions. Pricing starts at 4.99€/month for one bank connection, with +1.49€/month for each additional linked account.
