Keep straightforward tax logic in OneBill. Connect specialist engines when complexity increases.
OneBill supports two practical approaches to tax calculation, so the billing workflow can match the level of complexity your business actually needs.
Internal tax engine
Create and configure your own tax codes directly in OneBill when the tax structure is stable and does not require a highly complex specialist engine.
- Create tax codes around your own taxation requirements
- Associate the appropriate tax treatment with products and services
- Keep tax calculation inside the billing workflow
External tax engines
Connect OneBill to specialist taxation platforms when products, jurisdictions or industry-specific rules require more sophisticated tax calculation.
- Use pre-built integrations with supported tax platforms
- Pass transaction information to the selected tax engine for calculation
- Return the calculated tax to the OneBill billing transaction
Tax accuracy starts with the product, customer and transaction context.
Tax calculation should not be a disconnected step after billing. OneBill keeps the relevant commercial context attached to the transaction so the appropriate tax code or connected engine can be used during invoicing.
Apply tax without separating it from the revenue model.
Tax calculation sits alongside the billing logic in Billing360, so recurring charges, usage transactions, product-specific taxation and channel billing can stay connected to the invoice process.
Recurring billing
Calculate taxes as recurring charges move through the invoice workflow instead of handling taxation in a separate downstream process.
Usage-based billing
Keep tax calculation connected to the usage charges being rated and billed, especially when invoice values change with consumption.
Product taxability
Configure the appropriate tax treatment around the products and services your business sells instead of applying one generic rule to everything.
Partner taxation
Use Wholesale Tax Mode when channel partners need to be taxed for products that are resold to them.
Connect specialist tax calculation without disconnecting billing.
OneBill supports pre-built integrations with external tax platforms for businesses that need more complex tax calculation. Configure the account connection once, then let billing transactions use the selected engine for calculation.
Connect OneBill transactions to Avalara when your tax workflow uses Avalara as the calculation engine.
Tax solution
Use the supported SureTax integration for tax calculation requirements that need a specialist external engine.
Tax solution
Connect billing transactions to Compliance Solutions through OneBill’s supported tax integration workflow.
Tax solution
Use Vertex as the external tax calculation platform while keeping the resulting tax inside the billing transaction.
Tax solutionApply taxation when products are resold through your channel.
OneBill can tax channel partners for products resold to them using Wholesale Tax Mode. That keeps partner taxation inside the same revenue operation instead of pushing it into a separate manual process.

Common questions about tax automation in OneBill.
Detailed answers for finance, billing and revenue teams evaluating how taxation fits into recurring, usage and channel billing.
How does OneBill automate tax calculation?
OneBill captures the tax information required for the customer transaction, applies configured tax codes or communicates with a connected external tax engine, and includes the calculated tax in the billing flow. This keeps tax calculation attached to the transaction instead of treating it as a disconnected manual step after the invoice is created.
Does OneBill include its own tax engine?
Yes. OneBill includes an internal tax engine that lets businesses create and configure their own tax codes. The internal engine is a practical fit when tax requirements are relatively stable and do not require the complexity of a specialist external tax platform.
Businesses with more complex taxation can use supported external integrations instead of forcing those rules into the internal engine.
Which external tax platforms can OneBill integrate with?
OneBill supports pre-built integrations with Avalara, SureTax, Compliance Solutions, and Vertex. A business registers with the selected tax provider and configures the relevant account details in OneBill. OneBill can then communicate with that tax engine to calculate taxes for transactions processed through the billing workflow.
You can review the broader ecosystem on the OneBill integrations page.
Can OneBill calculate tax for recurring and usage-based invoices?
Yes. The taxation capability is designed for recurring and usage-based invoicing. Tax calculation can stay connected to the recurring charges and usage transactions that make up the invoice, rather than requiring finance teams to rebuild the tax logic outside the billing platform.
For the underlying billing models, see recurring billing and usage-based billing.
Can different products and services use different tax codes?
Yes. OneBill lets businesses create tax codes and configure taxation around the products and services they sell. That allows the billing workflow to use the relevant taxation treatment instead of assuming that every line item follows the same tax rule.
What is Wholesale Tax Mode in OneBill?
Wholesale Tax Mode lets a business tax its channel partners for products that are resold to them. The approach is similar to retail taxation for an end subscriber, but the taxable transaction is applied to the wholesale partner relationship.
This is particularly relevant for organizations using multi-level partner or reseller models alongside Channel360.
When should I use an external tax engine instead of OneBill’s internal tax engine?
Use OneBill’s internal tax engine when your tax requirements are stable and comparatively straightforward. If your business has complex, industry-specific or frequently changing tax requirements, a specialist tax platform can be the better calculation source.
OneBill’s role is then to keep the tax-engine interaction connected to the billing transaction, so the external calculation still flows back into the invoice process.
Keep tax calculation connected to the transaction that created it.
