Small businesses could soon bank inside their accounting software as Sage brings in Adyen and Mastercard

Small businesses that keep their books in Sage may soon get accounting software with a business bank account built in. Sage said on November 10, 2026, in Amsterdam, that Adyen will run the banking infrastructure and Mastercard the debit cards, with France first.

Key points

• Sage plans to put a business account, debit cards, payments and reconciliation inside its accounting software, alongside rather than instead of a company's existing bank.
• The first rollout is planned in France for Sage 50, Sage 100 and Sage Active.
• Adyen will supply the Banking-as-a-Service infrastructure and customer onboarding for the French launch.
• Mastercard will be the card network behind the service's debit cards.
• Sage says the model and its partners will vary from market to market as it expands across Europe.

Why would a small business bank inside its accounting software?

Because that is where many owners already say they want financial products. In a January 2026 Oliver Wyman survey of more than 150 small and mid-sized firms in France, Germany and the Netherlands, 53% named accounting and ERP software as their preferred place to get embedded finance, and 64% planned to take up new or additional finance products through their software provider within a year.

The same report finds the shift is further along in the US: embedded finance carries about two-thirds of small-business payment volume there, against roughly one-third even in advanced European markets. Sage frames its service around the work that sits between bank and books: according to the company, when the account and cards live inside Sage, entries post to the ledger as money moves, so owners see their cash position in real time instead of reconciling it later.

What does accounting software with a business bank account do?

It handles the money and the bookkeeping for it in one place. Sage says customers will be able to make payments, control company spending with debit cards and keep every transaction tied to their accounts, without re-entering data or reconciling in a second system.

This is the first implementation of our broader European Banking-as-a-Service strategy and an important step in helping customers manage more of their financial activity through Sage.

Mastercard, which supports the card side, says it sees the approach traveling beyond Europe.

Starting in Europe, we see an opportunity to bring this more connected approach to small businesses around the world.

What else is changing for small businesses in France?

The French launch comes as the country's e-invoicing reform phases in, a rule change that moves invoices and payment data into software. Sage names e-invoicing and digital reporting requirements, arriving country by country, among the pressures on small firms' financial tools.

Under the French tax authority's timetable for the e-invoicing reform, every business in France has had to be able to receive electronic invoices since September 1, 2026, the date large and intermediate-sized companies also began issuing them. From September 1, 2027, small and medium-sized businesses and micro-businesses must also issue invoices electronically and send transaction and payment data to the administration.

What does this mean for small businesses elsewhere?

Our analysis: the service is planned for France and then the other European markets where Sage operates, with partners that may change by country. For owners outside Europe, it is a signal of where accounting software is heading: the tool that records the money is starting to hold it too. That matters most for firms that match bank lines to ledger entries by hand, a chore that comes up in our pieces on how small businesses manage cash flow and managing finances in a startup.

Frequently asked questions

Will a Sage business account replace my current bank?

Which countries will get Sage's business account?

France comes first, through Sage 50, Sage 100 and Sage Active. Sage says it will then develop the service across the other European markets where it operates, with the approach and banking providers chosen market by market.

What role does Adyen play?

Adyen, the Dutch payments company, provides the Banking-as-a-Service infrastructure and handles onboarding of customers for the first implementation in France.

When must small French companies start issuing e-invoices?

From September 1, 2027, for small and medium-sized businesses and micro-businesses, according to the French tax authority's e-invoicing timetable. Receiving electronic invoices has been mandatory for all businesses since September 1, 2026.
