No, there is no separate charge for integrating Lightyear with Sage 300.

What type of connection does Lightyear have with Sage 300?

Lightyear connects to Sage 300 via CSV file export. Sage 300 is a desktop-based solution, so the integration works through a structured file export.

What data gets exported into Sage 300?

Each export includes the transaction type, supplier account reference, nominal account code, department code, invoice date, invoice reference, net amount, tax code, and tax amount. You can also add the due date manually in Sage 300 if required.

Can I import my existing Sage 300 suppliers and account codes into Lightyear?

Can I populate additional fields in the Sage 300 export manually?
