Open Banking for businesses: useful data sharing without losing control

Open Banking can let a business share bank-account data with regulated providers or initiate account-to-account payments through third-party services. The value comes from better visibility and automation, but the business should know exactly which accounts, users and data permissions it has authorised.

Understand what an Account Information Service Provider can access

The Open Banking Standard explains that Account Information Service Providers can access information from online payment accounts where the user has given explicit consent. For businesses, this can support consolidated dashboards, cash-flow tools, accounting feeds and other services that use bank transaction data.

The provider does not simply receive unlimited access because the company connected an account once. The consent journey specifies the data requested and the account provider authenticates the user. For corporate users, the authorised person may also need appropriate delegated authority inside the business bank before consent can be completed.

Treat every connection as an access-control decision

Before authorising a service, identify the legal provider, the accounts it needs and the data it will access. Give a cash-flow app access to the accounts required for forecasting rather than connecting every company account automatically. The business should know which person inside the company created the connection.

Document the purpose and owner of each connection. A useful register can contain provider name, service, connected accounts, date authorised and business owner. This makes access reviews much easier when employees leave or the company stops using a particular fintech tool.

Use account feeds to reduce manual bookkeeping, then reconcile them

Open Banking says business accountancy tools can use transaction data in near real time, helping businesses and accountants see current financial positions and reduce manual data entry. That can improve cash visibility and speed up reconciliation, especially where several accounts are involved.

Automation does not remove the need for reconciliation. Check that the feed imports the expected dates, descriptions and amounts and that duplicate transactions do not appear after re-authorisation. Keep original bank statements or provider records as evidence. The feed should make bookkeeping faster without becoming the only record of what the bank actually posted.

Understand the difference between sharing account data and initiating payments

Open Banking services can also support account-to-account payments. Open Banking Limited describes business use cases such as receiving customer payments, paying bills and creating payment journeys with pre-populated details. This can reduce manual entry and, in some cases, lower dependence on card payments.

Payment initiation is a different permission from simply reading account data. Keep approval authority clear. If accounting software can initiate payments, decide who can prepare them and who must authenticate or approve them at the bank. Automation should not turn one accounting login into uncontrolled payment authority.

Use bank-data sharing to speed applications without ignoring what the data reveals

Open Banking Limited notes that businesses can share account history with lenders and brokers to support faster credit decisions. This can reduce paperwork, but the data also shows real cash behaviour: overdraft reliance, returned payments, seasonality and customer concentration can all become visible.

Review the accounts before consenting. Make sure unusual transfers, director movements and temporary issues can be explained. Data sharing is most useful when it replaces repeated statement uploads while still giving the lender an accurate picture of the business rather than a selectively prepared snapshot.

Review and revoke third-party access when the service no longer has a job

Access should not accumulate permanently. Review connected services during the same user-access review used for banking and finance systems. Remove obsolete accounting apps, old lenders, abandoned cash-flow tools and connections created by former staff.

This also matters when switching banks. The Current Account Switch Service states that third-party permissions are not automatically transferred to the new account and may need to be re-authorised. Use the switch as an opportunity to reconnect only the tools the business still needs rather than recreating every historic connection by default.
