Open banking is the system that lets budgeting apps, accounting software, and forecasting tools see your actual account data, balances, transactions, cash flow, directly from your bank, instead of you manually entering numbers or uploading statements.
How it actually works
Before open banking, connecting a financial app to your bank often meant handing over your actual online banking username and password, which the app then used to log in and scrape your data. Open banking replaces that with a secure, permissioned connection: you authorize a specific app to access specific data through your bank directly, and you can revoke that access at any time without changing your banking password.
Why this matters for cash flow specifically
Cash flow tracking is only useful if the numbers are current. A spreadsheet updated once a week is already stale by the time you're looking at it. Open banking connections update automatically, often in real time, which means a cash flow dashboard or forecasting tool actually reflects what's in your accounts right now, not what was there last time you remembered to check.
What it enables in practice
- Real-time cash position: see your actual available cash across multiple accounts in one place, instead of logging into three different bank portals
- Automatic categorization: transactions get sorted into income, expenses, and categories without manual entry
- Faster forecasting: tools that connect via open banking can project near-term cash flow using your actual transaction history rather than estimates you type in
- Fewer manual errors: data pulled directly from the bank removes the transcription mistakes that come with manual entry
What to check before connecting an account
- Confirm the app uses a regulated open banking connection rather than screen-scraping with your actual login credentials
- Check exactly what data access you're granting, read-only account data is standard; anything asking for the ability to move money should get more scrutiny
- Know that you can revoke access from your bank's side at any time, this isn't a one-way door
Where this fits into your broader setup
Open banking is the plumbing underneath most modern cash flow forecasting software, it's what makes automatic, real-time forecasting possible instead of forecasting built on manually updated spreadsheets. If you're evaluating tools, whether they connect this way is one of the first things worth checking.
