Tax-Exempt Purchasing Software: How to Compare Vendors

Software for tax-exempt purchasing: generate, issue, and track the certificates you give vendors, catch tax charged on exempt purchases, and keep the evidence attached.

Sales-side and purchasing-side exemption certificate management are included in every plan, or standalone from $49/month per side.
AI-native since 2019: AI reads your documents, classifies every transaction for taxability, validates exemption certificates, and answers questions in-app — checked against published state rules, with a person approving every material decision.
Human review is a designed control: filing-ready outputs are approved by a reviewer, and unresolved facts fail closed instead of being guessed.
Flat pricing per organization: $199/month Starter and $599/month Professional, with no per-state, per-filing, or per-transaction fees — plus a published à-la-carte module menu.
