The Numeral SuiteTax Engine is a SuiteApp that registers Numeral as a tax provider in NetSuite’s SuiteTax framework. Once enabled and configured, NetSuite calls Numeral whenever you preview or save tax on a sales transaction, and the resulting tax detail is recorded back to Numeral.Documentation Index

This integration requires NetSuite with the SuiteTax feature enabled. Legacy tax engine accounts are not supported.
What you’ll do
- Install the Numeral SuiteApp
- Verify the Numeral SuiteTax Engine plug-in is enabled
- Configure the Numeral Credentials record
- Configure your NetSuite Nexuses, Tax Codes, and Tax Types
- Test on a Sales Invoice
1. Install the SuiteApp
Numeral will share a private SuiteApp installation link. Install it under Customization → SuiteBundler → Search & Install Bundles (legacy) or via Customization → SuiteApps (modern). After installation completes, the bundle deploys:- A SuiteTax plug-in implementation called Numeral SuiteTax Engine
- A custom record type called Numeral Credentials
- Supporting scripts for transaction events
2. Enable the SuiteTax plug-in
Go to Customization → Plug-ins → Manage Plug-ins and confirm Numeral SuiteTax Engine is checked.This checkbox is the integration’s kill switch — unchecking it disables Numeral tax calculation NetSuite-wide without uninstalling the bundle.
3. Configure Numeral Credentials
Go to Customization → Lists, Records, and Fields → Record Types and open the Numeral Credentials record type. Click New Record and provide:| Field | Value |
|---|---|
| API Key | A sk_test_* or sk_prod_* key from your Numeral dashboard |
| API Endpoint | The Numeral API endpoint Numeral provided |
| Test Mode | Enable while validating |

4. Configure Nexuses, Tax Codes, and Tax Types
NetSuite requires tax results to map onto the existing Nexus, Tax Code, and Tax Type records on the account. The Numeral SuiteTax Engine matches Numeral’s calculated jurisdictions to NetSuite records by state, so each US state where you have nexus needs to have:- A NetSuite Nexus (Setup → Tax → Nexuses)
- A Tax Code assigned to that Nexus (Setup → Tax → Tax Codes)
- A Tax Type assigned to that Nexus (Setup → Tax → Tax Types)
5. Test on a Sales Invoice
- Go to Transactions → Sales → Create Invoices
- Select a customer with a US shipping address
- Add at least one line item
- Click Preview Tax

Add a Nexus for that state (Setup → Tax → Nexuses) along with a Tax Code and Tax Type assigned to that Nexus. Numeral matches by Nexus state.
