Declined Services

GTX-31373 – Invoice Entry: Enhanced job attributes to support declined services and upsell situations.

Screenshot from the GTX 5.8.3 help article

Recommended services that have been declined by customers can now be tracked and followed-up on without removing them from the Work Order.

Declined lines remain visible on orders so staff can see what was recommended and why it was not carried out, with follow-ups automatically created to prompt future contact with the customer.

Previously declined services can be imported into new orders, so that the recommendation can be actioned later without re-entering the details, or marked as Lost if the work has been carried out elsewhere.

See the Declined Services help guide for further information.
