Creating a Purchase Invoice from Construction Contract Materials

The Purchase Invoice option creates a purchase invoice for the selected contract materials, linked to the contract project, with the cost centers of each line filled automatically. Use it when buying the materials directly without requests or orders.

After Saving

• The invoice page opens directly (you don’t return to the contract).
• The usual purchase invoice journal entry is created, and the line amounts are charged to the distributed cost centers.
• The stock transaction is recorded according to the receiving status, like any purchase invoice.
• Cancel takes you back to Purchase Invoices.

Cost Centers in the Invoice

• Cost centers appear for each line only if you enable Purchase Invoices under Item-Level Cost Center Assignment by Transaction Type in General Accounting Settings.
• Project: all lines go to the project center. Tenders: the center of the parent sub-tender of the work item. Work Item: the work item center.
• A material in more than one item is distributed by its value (60%/40%), shared centers are combined, and lines split by unit are calculated separately.
• The values are not locked and can be edited.
