To utilize the Reverse VAT function with your Tradify-Sage integration, you'll first need to enable Reverse VAT in your Sage account. To achieve this (and to learn more about Reverse VAT), have a look here.

Important: Reverse VAT in Tradify works alongside the Construction Industry Scheme (CIS). To see Reverse VAT settings on a customer or supplier in Tradify, CIS must also be enabled for that contact in Sage. If you've enabled Reverse VAT but not CIS for a contact, the Reverse VAT setting won't appear in Tradify. For help enabling CIS, see CIS & Sage.

Enabling Reverse VAT for a customer

When creating a new invoice, Tradify will first check to see if the customer has Reverse VAT enabled in Sage. If they do, the customer record in Tradify will be updated to match (as highlighted below).

Note: If the update hasn't come through, please double-check the customer record in Sage by going to Contacts > Customers > Options > Account Details > VAT Reverse Charge.

Creating Invoices for Customers with Reverse VAT

Tax method update:

When creating a new invoice for a customer with Reverse VAT enabled, you'll notice the tax method will auto-update based on your default tax settings. If your sales default tax type is set to Exclusive, it will update to Reverse Charge - Excl. If it's set to Inclusive, it will update to Reverse Charge - Incl.
