MasterTax

MasterTax is a provider of payroll tax filing software. The job it does: accepting cards, bank transfers and wallets online or in person.

Who is it for? Mostly any business that takes money. They also list Payments, so expect those to show up in the feature set. As a mid-sized product team themselves (51 to 200 people), they tend to serve customers of a similar scale best.

MasterTax is based in Scottsdale, Arizona. Their site is mastertax.com.

Things worth asking about: rates, payout timing, chargeback handling, and developer tools. Get the renewal terms in writing before the first invoice.

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