Sales tax calculation isn't just about the rate. CereTax validates, calculates, and records every detail, at the line-item level, at the speed your business requires.
Step 1: Validate
CereTax verifies every address and determines the taxable status of each line item — who's buying, what they're buying, where it's going, and why it's taxable.
Step 2: Calculate
CereTax applies the correct rates, sourcing rules, and exemption logic. Rooftop-level precision. Milliseconds, not minutes.
Step 3: Populate
Invoice-ready output with full line-item detail and rooftop level accuracy. Compliant, documented, and audit-safe.
Step 4: Aggregate
Every transaction is captured for reporting, reconciliation, and compliance review so quarter-end isn't a scramble.
Step 5: Update
Your billing or ERP system reflects the tax calculation instantly. Nothing falls through the cracks.
CereTax connects to billing, accounting, ecommerce, and ERP systems with stable, documented integrations that don't require babysitting.
CereTax is purpose-built for industries where tax nuance isn't optional — physical goods, services, exemptions, specialty taxes, and multi-jurisdiction complexity included.
