Tessera Opens Its Data Reconciliation Engine to Third-Party Developers
The company's first public API turns a single-purpose tool into a platform other systems can build on, and arrives with SOC 2 Type II certification
AUSTIN, Texas — 9 April 2026
Tessera has released a public API for its data reconciliation engine, allowing third-party developers to run reconciliation jobs from their own systems for the first time. The release moves the company beyond its original single-purpose application and is available to all customers on the Growth and Enterprise tiers from today.
Tessera's engine compares records across systems that disagree — typically a billing platform, a general ledger, and a payment processor — and reports the differences with the reasoning attached. Until now that comparison could only be run inside Tessera's own interface. The API allows finance and engineering teams to trigger the same jobs from an internal tool, a scheduled task, or another application.
“Roughly a third of our support conversations were customers asking how to get a reconciliation result out of our interface and into something else. That is a fairly direct signal that the product boundary was in the wrong place. We were the last step in a process that should have been able to call us.”
Alongside the API, Tessera has completed a SOC 2 Type II examination covering security and availability, conducted over a six-month observation period ending February 2026. The company has also published integration guides for three accounting systems its customers commonly run.
Founded in 2021, Tessera serves approximately 480 business customers, principally in subscription software and marketplace businesses. The company employs 61 people and has offices in Austin, Texas and Lisbon, Portugal.
The API was tested with 40 customers during a private preview that ran from November 2025. Tessera reports that preview participants ran an average of 320 reconciliation jobs a month through the API, against an average of 45 run manually in the interface over the same period. The company has published a migration guide for teams moving scheduled work off the interface.
Access to the API is included at no additional cost for existing Growth and Enterprise customers. Rate limits and full documentation are published at tessera.example/docs.
