The extended workbench allows you to store external resources as a Resource/Warehouse/Supplier. Create Price inquiries, Purchase Orders, Contracts, Goods Receipt Slips (goods issue), and Collective Goods Receipt Slips. Manage prices and confirm Goods Receipt Slips (goods receipt) and switch between internal and external production. You also have the option of sending reminders to suppliers and creating Goods Receipt invoices.

Side note:

It is rare for a company to function without utilizing external processors. Above all, the integration of the extended workbench in planning, costing, logistics, and feedback is a particular challenge. The extended workbench in Titanium.aero maps all essential processes of external processing using different document types: External contract, External purchase order, Goods Receipt Slip (on delivery of the raw materials), Confirmation from external production and automatic goods receipt document transfer to Purchasing are the key milestones in the order flow of external production.
