Modern Tax Compliance, Built for NetSuite.
CereTax is a cloud-native sales and use tax platform that calculates the right tax on every NetSuite transaction — in real time, with rooftop-level GIS accuracy, across every U.S. jurisdiction. Founded by veteran tax technologists, CereTax was purpose-built as a modern alternative to legacy platforms — with transparent pricing, faster implementations, and a procure-to-pay use tax module that legacy tools simply don't offer.
The tax engine your NetSuite deserves.
Most NetSuite customers are still on legacy tax platforms built before modern cloud infrastructure existed — or managing compliance manually. CereTax was built from scratch in 2021 to fix that.
Real-Time Sales Tax Calculation
CereTax's calculation engine applies the correct tax rates, rules, and product taxability logic in milliseconds — using rooftop-level GIS geospatial mapping to pinpoint the exact tax jurisdiction for every ship-to address, not ZIP-code-based lookups. Every calculation is transparent: rates applied, sourcing logic, and exemptions invoked are all visible and defensible, giving your tax team output they can stand behind in an audit. Covers all U.S. state, county, city, and special taxing districts — updated continuously with no manual content maintenance required.
SmartExempt — Exemption Certificate Management
SmartExempt centralizes the entire exemption certificate lifecycle: certificates are auto-validated for format, jurisdiction, and expiration at submission, stored in a searchable cloud repository, and applied in real time during tax calculation. The system flags expiring certificates proactively and auto-notifies buyers or resellers to renew — supporting bulk uploads and API-based submission for high-volume B2B sellers. No valid certificate is ever missed, and no invalid one is ever honored.
Procure-to-Pay Use Tax Automation
Most tax automation tools focus only on the sales side — CereTax also automates use tax on the purchasing side, catching the variance between what a vendor charged and what you actually owe. CereTax integrates into the requisition-through-invoice-approval workflow within NetSuite, flagging likely overpayments in real time so AP can short-pay the tax and recover cash immediately rather than filing refund claims years later. For manufacturers and distributors with high purchase volumes, P2P use tax automation directly recovers dollars that would otherwise be lost to vendor overcharges.
CereTax compliance across the industries we serve.
Tax accuracy on every purchase and every sale.
Manufacturers face some of the most complex tax environments of any industry — with production equipment exemptions, raw material rules, and use tax on purchased inputs that vary by state and shift constantly. A single miscategorized item can mean years of overpaid tax on purchases or a use tax liability that surfaces in an audit. CereTax handles both sides: real-time exemption logic on manufacturing inputs at the point of purchase, and accurate jurisdiction-level tax calculation on every sales transaction across every state where you have nexus.
Manufacturing exemption accuracy at the line-item level
CereTax applies production equipment and raw material exemption rules to every purchase transaction — across all relevant jurisdictions — so you stop paying tax on inputs that should be exempt and stop leaving exemption savings on the table.
P2P use tax recovery on purchased inputs
CereTax's procure-to-pay module flags vendor tax overcharges in real time, allowing AP teams to short-pay the tax variance on the invoice instead of filing refund claims months or years later.
Multi-state nexus compliance without manual updates
As your manufacturing footprint expands across states, CereTax continuously applies current rate and rule changes — no manual content updates, no lag between a jurisdiction change and your next transaction.
Audit-ready calculation records on every transaction
Every calculation shows the rates applied, sourcing basis, and exemptions invoked — giving your finance team a complete, transparent audit trail without reconstructing calculations from scratch.
Reduction in time spent on manual tax review — manufacturers using CereTax report significantly fewer hours auditing purchase invoices and reconciling calculations.
Uptime SLA on CereTax's multi-regional cloud infrastructure — production and fulfillment workflows never wait on tax calculation.
Typical go-live for manufacturers via the Oracle-certified CereTax SuiteApp — versus the 12–18 months legacy platforms commonly require.
Tax compliance only works when it's configured correctly.
CereTax's Oracle-certified SuiteApp gives you a modern foundation — but connecting the SuiteApp is just the starting point. The value comes from how it's configured inside your specific NetSuite environment: product and service tax codes mapped to your item catalog, nexus registered for every jurisdiction you sell into, exemption workflows embedded in your AR and AP processes, and calculation logic validated against your actual transaction scenarios. Get any of these wrong and the automation creates a false sense of security.
Sky High has the NetSuite depth to configure CereTax to your exact business structure — so compliance is accurate from day one and scales cleanly as your tax footprint grows.
Tax Compliance Assessment & Nexus Mapping
We work with your finance and tax team to map your current nexus footprint, identify where you have economic nexus obligations, and audit your existing NetSuite tax code setup for gaps. We document your product and service taxability matrix and exemption certificate status — so CereTax is configured around your actual compliance posture, not a generic template.
CereTax SuiteApp Installation & Configuration
We install the Oracle-certified CereTax SuiteApp directly within your NetSuite account and configure API credentials, tax code assignments, and product taxability mappings. This includes setting up CereTax response handling in NetSuite, mass-updating customer records with the correct tax code assignments, and validating that address validation and calculation settings are correctly aligned to your business entities and transaction flows.
Parallel Testing & Validation
Before go-live, we run CereTax in parallel with your existing tax calculation method — comparing outputs transaction by transaction across your most common scenarios: standard sales, exempt sales, multi-state orders, bundled products, and freight. Any discrepancies are resolved by adjusting product taxability rules or exemption assignments, and your team signs off on validated logic before cutover.
Go-Live, Training & Ongoing Optimization
We manage the cutover to CereTax as the live tax engine within NetSuite, provide role-based training for your AP, AR, and finance teams, and remain engaged post-go-live to monitor calculation accuracy and address edge cases as your business evolves. Because CereTax maintains its own tax content continuously, there are no quarterly manual updates — but Sky High stays available as your NetSuite grows to ensure CereTax scales with new entities, product lines, and nexus states.
“We were live in under 30 days and haven’t had to think about tax compliance since. Every calculation is transparent, every certificate is tracked, and our audit exposure went from constant concern to complete non-issue.”
