Basware, the invoice lifecycle management company, completed its acquisition of the payment fraud prevention platform Trustpair, with the closing announced on 5 October 2026 after the agreement was first made public in August. The Basware Trustpair combination links an invoice authenticity check with a test of whether the supplier bank account behind the payment is genuine.

What Basware Trustpair actually combines

Basware says it can confirm that an invoice is genuine, correct, compliant and signed off. Trustpair adds the next question: whether the supplier is real, whether that supplier holds the bank account, and whether the money is headed where it should. The company describes the pairing as lifecycle assurance from invoice to payment.

Basware reports more than 6,500 customers, with DHL, Heineken and NBC Universal Media among those it names. Trustpair, based in Paris with offices in New York City and London, says it secures payments for more than 600 organisations and holds SOC 2 Type II and ISO 27001 certification. It will keep operating independently, with its own platform, contracts and support, and Basware says it will keep integrating with ERP, treasury, procure-to-pay and payment systems, whether or not a customer uses Basware.

Fintechbits analysis

Why the Basware Trustpair logic fits how payment fraud works

Fraud against finance teams has moved away from forging an invoice and toward changing who gets paid. A genuine invoice with an altered supplier bank account passes every approval step and still sends the money to the wrong place. Basware’s own words in the release make that point: an invoice can be authentic and the payment still wrong. Trustpair chief executive Baptiste Collot argued that fraud prevention has to run as an active layer across the whole invoice and payment lifecycle, particularly as AI makes attacks more convincing.

Fintechbits regards that diagnosis as correct, and it is why a payment control sits better beside accounts payable data than as a standalone product. A comparable idea appears in Mastercard’s Agent Pay, covered by Fintechbits in its report on a probability score for AI-initiated purchases, which tells issuers and merchants when an AI agent started a transaction. Basware and Trustpair work at the supplier level instead of the card level.

What Basware and Trustpair have not said

The release states a data ambition without evidence of results. Basware says its own data spans 20 million suppliers and 2.5 billion invoices, and says the two companies see a longer-term chance to combine that context with Trustpair’s fraud intelligence. It gives no timetable, no product name, and no measure such as fraud losses prevented or false positive rates. Those figures come from the companies themselves and are not independently checked.

The independence promise deserves more scrutiny than it received. Basware says Trustpair customers can run it without using Basware, as its own webinar page on the deal also frames it. Trustpair’s newsroom, listed on the same BusinessWire page, shows earlier partnerships with Coupa, an alternative spend management platform, and with the third-party risk company Certa. A finance team on Coupa will want to know how its supplier data is handled once it passes through a Basware-owned business, and the release offers no data-handling commitment on that point.

There is also no price. Without it, readers cannot judge whether Basware paid for Trustpair’s customer base, its technology or the dataset. Fintechbits’ report on Emburse AP, launched on 16 September, shows the same market from the other direction, with invoice processing, approvals and payments bundled for growing businesses.

What to Watch Next

Watch for the first named Trustpair customer that runs on a non-Basware ERP after the closing, and for any statement on how supplier data is separated between the two businesses. That would show whether the Basware Trustpair open ecosystem pledge survives contact with Basware’s own sales targets, and whether the 2.5 billion invoice dataset starts to appear in product features.
