Sublet is the process of outsourcing work for another company to carry out for you but you then carry the cost of it and on charge the customer.

There is a full article on the Job to Creditor invoicing sublet repairs which may be more up to date available here http://service.autosoft.com.au/entries/21464084-How-to-do-a-sublet-and-process-a-sublet-to-a-Job-in-Autosoft-correctly-

In the Creditor Invoice screen when you select the Add Sublet

You have the ability to assign a Sublet Repair and its cost to an open or closed Repair Order / Workshop invoice. The system will automatically adjust the general ledger if the invoice is processed and the sublet cost has changed. 

RO Number - Find the Repair Order by clicking on the ellipsis or press F4.  If the Repair Order is already closed, find the RO by clicking on the Select Closed RO button.

Existing Sublet - Select the sublet that has already been added to the RO.

OR

Sublet Item - Select a sublet to add to the RO.

Sublet Description - Enter the description of the sublet, if required.

Cost Ex - Enter the cost of the sublet repair.

Markup % - Enter the markup percentage.

Sell Price Ex - Enter the sell price.  If you have entered a Markup % and Cost, the system will calculate the Sell Price for you.

This will create an entry in the General Ledger Tab of the Creditor Invoice, with the information on the sublet General Ledger account coming from the map of Control Accounts. This entry can be manually changed.

This only covers the work that has been sublet out to a third party, the invoice you provide to the client will not contain any of the information from this sublet information, rather it will utilise the job-code that represents sublet repairs in your Job Code Maintenance.

General Ledger Tab

The General Ledger Tab is a means of processing an invoice directly against a specific GL account. This will not alter any values in the Stock Master File, and can be used for non-parts purchases. There can be entries on both the GL Tab and the Parts tab on a single Creditor Invoice.
