**Marlin GTX** enables deposits to be taken when a customer pays part or all of an order before it is invoiced.

Deposits are linked to work orders and reduce the amount owing when the invoice is finalised.

Deposits can be taken once or across multiple payments, or refunded or forfeited if required.

Taking Deposits

Deposits can be added by opening the relevant work order.

To take a deposit:

  • Add at least one product
  • Enter the deposit amount in the New Deposit field at the top
  • Save the work order
  • Process the payment
  • Provide a receipt to the customer

The deposit amount is automatically applied to the total when the invoice is finalised.

Additional Deposits

Additional deposits can be taken at any time.

To take additional deposits:

  • Open the relevant work order
  • Enter the new deposit amount in the New Deposit field
  • Save and process the payment
