Assign tax categories to products
Every product in a billing schedule must have a tax category assigned in Sequence, unless the customer is tax exempt.
Assign any tax category to each product. Sphere calculates the actual rate based on your customer’s location.
- Existing customers
- New customers
If you are an existing Sequence customer connecting Sphere, make sure every product you actively use has a tax category assigned. Go to Settings > Products to review and update any products that are missing one.
How it works
Customer and product sync When you connect Sphere, existing customers and products sync automatically. New customers and updates sync as they’re created. New customers and product updates will show the Sphere link indicator in the dashboard. For existing customers, the indicator may take a moment to appear. Tax rates on invoices Once Sphere is connected, tax is calculated automatically on every invoice. Sphere determines the correct rate based on your customer’s location and tax legislation. When creating a billing schedule, you may be prompted to enter a tax rate percentage if none has been configured for that customer’s country. Enter any value; Sphere will overwrite it with the correct rate when the invoice is generated.
