The news
Basware, the accounts payable software company, said on October 5, 2026 that it has completed its acquisition of Trustpair, a Paris-founded platform that checks supplier identities and bank account details before companies pay them. The companies did not disclose the price.
The deal closes an agreement first announced on August 26, 2026. At that time, coverage of the announcement said closing was expected later in 2026, subject to customary conditions. The completion release, datelined Paris, did not mention any outstanding conditions.
Trustpair describes its product as AI-driven payment fraud prevention. It validates vendor bank details at onboarding, when a supplier asks to change payment details, and before payments are authorized. According to the announcement, it serves more than 600 organizations, including Fortune 500 companies, and has offices in New York City, Paris and London. It holds SOC 2 Type II and ISO 27001 certifications.
Basware calls itself a leader in what it terms invoice lifecycle management. The company says it serves more than 6,500 customers, including DHL, Heineken and NBC Universal Media, and that its network covers 2.5 billion invoices and 20 million suppliers. Basware is backed by the private equity firm Accel-KKR, according to Pulse 2's coverage of the August agreement.
Basware CEO Jason Kurtz framed the deal around a gap that invoice checks alone cannot close. An invoice can be authentic and accurate, he said, but the outcome is wrong if payment goes to the wrong account. Trustpair co-founder and CEO Baptiste Collot said finance leaders can no longer treat the invoice separately from payment assurance.
Basware said Trustpair will keep its platform, team and customer relationships, and will remain system-agnostic. Pulse 2 reported that Trustpair works with systems including SAP, Oracle, Coupa, Ivalua, Jaggaer and Kyriba, so existing customers are not required to switch providers.

Why CEOs should care
For CFOs and controllers, the deal targets one of the most common ways money is stolen from companies: a fraudster poses as a real supplier and asks finance to send payments to a new bank account. Invoice-matching software can confirm that a bill is real and correct and still miss that the payee account has changed. Ask your accounts payable team who verifies a bank-detail change today, how, and whether any payment can be released before that check is done.
For buyers of finance software, the main promise is that Trustpair stays independent and works with any ERP or payment platform. That matters for Trustpair customers that do not use Basware. Put the commitment in writing at renewal: integration support for your current systems, data-use terms for the shared supplier intelligence Basware describes, and what happens to pricing if the products are later bundled.
For CISOs and audit committees, payment fraud sits between finance and security. Pulse 2 cited survey data in which 75% of anti-fraud professionals reported more AI-related document fraud over the past two years. Fake invoices and voice or email impersonation are getting cheaper to produce, so boards should ask management how vendor master data is protected and who owns that control.
The bigger picture
The deal fits a broader push to fold fraud controls into the software that already moves business payments, rather than leaving them to separate tools or manual phone callbacks. Pulse 2 noted that Nacha, which governs the US ACH network, tightened its fraud-monitoring requirements in 2026, adding a compliance reason for companies to check payees more carefully.
Basware has been buying steadily under Accel-KKR's ownership, with deals for Glantus, AP Matching and Redmap between 2023 and 2025, according to Pulse 2. Trustpair takes it past invoice processing into checks on the payment itself.
What’s next
Basware has not said when, or whether, Trustpair's checks will be built directly into its own invoice workflows, or how the pair will be priced together. Customers of both companies should watch for product roadmaps and contract changes over the coming renewal cycles.
What “Fact-checked” means
Fact-checking means testing a story’s facts against the evidence before it is published. This story went through at least two separate checks before this version was published.
- What we checked
- Its names, figures, dates, job titles, quotes and who said what were checked against the story’s sources, including its main source where it could be opened. The headline was checked for accuracy and overstatement.
- How
- A first check reviewed the whole story. If it passed, a second, skeptical check went back to the sources to look for mistakes in the most important facts. If a check flagged the story, it was edited to fix the problems found, and a separate re-check then reviewed the whole story again.
- Who
- The checks are made by our newsroom, as steps kept separate from the writing, under rules set by our editor, Hussein Mukhtar. A story the checks still flag is held for the editor, who decides whether it is fixed, published or dropped.
- If something is wrong
- “Fact-checked” does not mean error-free. If a material error is found after publication, we correct the story and add a note saying what changed. Report an error
