Before you decide, you will want to know this
Every answer comes from the API documentation and the published measurement.

Will we catch a wrong buyer tax ID before filing?
The API returns the seller’s and the buyer’s tax IDs as separate fields, so your system can compare them with your own the day the bill arrives.
Can we send PDFs?
Yes, PDFs as well as JPG, PNG or HEIC photos, billed per page actually read.
Is there a monthly fee or a minimum term?
No. You pay per page used, credits never expire, and failed requests are not charged.
How long does integration take?
One HTTP POST, with examples in curl, Python and JavaScript, and an open-source SDK for web and apps. Try it on the free credits before you write production code.
Can we get a tax invoice in our company’s name?
Yes. Request it from the credits page of your account after you pay.
