GTX enables deposits to be recorded when a customer makes a partial payment or a prepayment toward a purchase.

Deposits reduce the balance owed when the sale is finalised and can be refunded or forfeited if the sale is cancelled.

Taking Deposits

... > Work Order

A deposit is linked to the work order for a pending sale and can be taken once or in multiple instalments.
