Chart

Chart provides an API that accesses IRS and state tax data, helping fintech platforms streamline financial verification processes. The job it does: accepting cards, bank transfers and wallets online or in person.

It makes the most sense for any business that takes money. They also list Financial Services and FinTech, so expect those to show up in the feature set. As a very small product team themselves (1 to 10 people), they tend to serve customers of a similar scale best. Small vendors mean quick answers and real influence on the roadmap, but check who covers support when someone is out.

Chart is based in San Francisco, California. More on trychart.com.

Our checklist for this category: rates, payout timing, chargeback handling, and developer tools. Ask for a trial on your own data, not a canned demo.

If you have worked with Chart, tell the next buyer what you paid and what surprised you. That is the part of this page we cannot write.
