What changes
Legacy tax engines add work as a business grows: more overrides, more manual checks, and more errors to fix before each filing. CereTax calculates the tax at the transaction and keeps the record, so your team gets those hours back.
Retire the spreadsheets, overrides, and custom scripts that keep tax right today.
Add products, entities, and jurisdictions without rebuilding your tax setup.
Every transaction keeps its rate, rule, and source, so you can answer an auditor from the record.
Experienced tax professionals who understand the question and help move it forward.
By the numbers
CereTax integrates with platforms that move more than $4 trillion in transactions each year.

Questions
Here are the questions we hear most from teams weighing a switch.
Most legacy tax engines began with simple retail sales and added complexity later, so companies with high volumes, many jurisdictions, or industry taxes end up fixing results by hand. CereTax calculates sales tax at the transaction and shows the jurisdiction, the rule, and the source behind every rate.
Most deployments take less than 90 days, and prebuilt integrations connect in days. Our team supports the implementation from the first call.
