Purchase Orders (PO)

A Purchase Order (PO) can only be issued after a Purchase Request has been approved. The purchasing team selects a supplier, confirms pricing, and sends the PO for a final approval before placing the actual order.

Creating a Purchase Order

1. Go to Purchase Orders (PO) → click “Create Purchase Order”
2. Select the approved PR you want to convert into a PO
3. Select a Supplier from the list already registered in the system
4. Review the line items pulled from the PR — you can adjust the unit price for each item
5. Enter any Discount and VAT (if applicable) — the system calculates the total automatically
6. Enter the Project and a Note (if applicable)
7. Click “Submit for Approval” — the system will show a preview of the LINE recipients before you confirm

Printing a PO as PDF

1. Open the PO you want to print
2. Click the “Print / PDF” button in the top-right corner
3. Your browser’s print dialog will open — choose “Save as PDF” or send it directly to the printer for the supplier

PO Approval Levels

POs are subject to a two-tier approval process based on the order value.

Order Value	Approver(s)
Up to 50,000 THB	Purchasing
Over 50,000 THB	Purchasing → Owner

Tip

High-value POs cannot be approved in a single step — the owner must give final approval. The system sends a LINE card to each approver in sequence automatically.

Caution

Verify the pricing and supplier details carefully before submitting for approval, as the PO cannot be edited once it has been submitted.
