Maxio + Sphere:
An AI-native tax engine, connected to your billing
Global VAT, GST, and sales tax calculation, built into Advanced Billing.
Maxio’s Sphere integration brings automated global indirect tax calculation directly into Maxio. At invoice time, Sphere applies the correct VAT, GST, and sales tax for each transaction based on customer location and product type—no manual rates, no workarounds.
Why Maxio + Sphere

Built for global B2B SaaS and AI complexity.
Sphere has direct integrations into 100+ tax authorities for sales tax, VAT, and GST, enabling global end-to-end registration, calculation, filing and remittance, natively on platform.
Go live without needing any engineering work.
Sphere credentials are configured and validated directly in the Maxio, so there is no custom build to go live.
No tax rebuild when you move to Maxio.
Sphere connects directly. Configure your tax codes once and billing handles the rest. No implementation project, no outside help required.
How it works
Sphere acts as your external tax engine. Maxio sends the data, Sphere returns the tax, and Maxio adds tax in real-time to the invoice.
Map your product and component IDs inside Sphere first. This step is required before the integration will calculate correctly.
Enter and validate your Sphere credentials in Maxio’s tax settings.
Maxio passes product IDs, customer addresses and more to Sphere’s engine, which returns correct tax amounts globally.
Maxio stores the calculated tax on the invoice.
Who it is for
For businesses that need a true international tax solution, with calculation handled automatically at invoice time, plus registration, filing and remittance handled in one place, globally. Sphere manages the rules; Maxio applies them to every invoice.

Avalara
Maxio + Avalara AvaTax Integration
Save time and avoid confusion by automating sales tax calculations and filings. Maxio’s AvaTax integration allows you to quickly and accurately calculate sales tax to remain compliant with ever-changing tax laws.
Why integrate Avalara AvaTax with your Maxio account
Address Validation
As you create customers in Maxio, you can validate the business addresses using AvaTax (you can also validate your customers’ addresses in bulk). The AvaTax calculation engine is the most accurate and up-to-date address validation engine available, so you will know that your records are accurate and your Sales Tax will be calculated correctly.
Automate Tax Calculations
With a validated address, AvaTax auto-calculates sales tax based on the local tax code for each invoice. Sales tax is calculated based on the jurisdiction at which the service is delivered. This can be either the shipping address or billing address. When committing sales tax, you’ll have the flexibility to choose between doing so manually or automatically in Maxio.
Accuracy Across all Applications
Maxio is designed to be your source of truth for revenue. All sales tax line items populated by AvaTax can be passed to your CRM or general ledger so you have accurate customer data across all applications.
How the Maxio + Avalara AvaTax integration works
The Maxio + Avalara AvaTax integration is bi-directional. Maxio syncs with your AvaTax account and passes Maxio Items to AvaTax and AvaTax passes your entity use codes to Maxio. Once synced, you can reference the AvaTax information for your Items from both the Item List and the individual Item Profiles within Maxio.
Once configured, AvaTax calculates the sales tax amount for each invoice based on a combination of the item tax code settings in AvaTax, the presence of any exemptions for the customer, and the physical location associated with the invoice.
Sales tax is typically calculated based on the location to which the service is delivered. Using this logic, AvaTax will attempt to use an invoice’s shipping address to assign tax values and will only use the billing address when there are no valid shipping addresses.
To get started using AvaTax with Maxio, contact Maxio Support and we will provide you with instructions for contacting AvaTax. You must first have an account set up with AvaTax in order to use the integration.
Once you’re live with AvaTax, it takes about 10 minutes to enable the integration in your Maxio account.
