01 — The certificate

Your buyer has a certificate.

A resale certificate sitting in a PDF. Somewhere. Usually in an email thread nobody can find.

02 — The drop

They drop it at checkout.

No emails. No order desk. It uploads right inside your Wix store — mid purchase.

03 — The landing

It lands. Tax handled.

Validated, tracked, and exempt — before the order is even placed. Every time after, automatically.

The Problem

Tax Exemption Management is Broken

Businesses struggle with outdated processes, compliance headaches, and costly mistakes that drain resources and put them at risk.

Hours of Manual Work

Finance and ops teams spend hours each week manually chasing certificates and reconciling exemption status across orders.

15+hours/week wasted

Missing Certificates

Most B2B merchants have incomplete or expired exemption documentation — a liability when audits happen.

67%have gaps in records

Compliance Risks

Invalid exemptions leave merchants exposed. Audits are expensive and time-consuming without a clear paper trail.

$25Kavg. audit penalty

Checkout Inaccuracy

Without line-item-aware tax math and a reliable fallback rate, buyers get charged the wrong amount at checkout.
