Purchase Order Management
Purchase order management is the bridge between knowing what you need (MRP) and having it on the shelf (inventory). For job shops, purchasing is often reactive — you find out you need material when the job hits the floor. A proper PO system makes purchasing proactive by creating orders based on upcoming demand, tracking deliveries, and managing vendor relationships.
From shortage to PO
The ideal flow: MRP identifies that Job 2847 needs 50 lbs of 4140 steel, due on the floor in 2 weeks. Your vendor lead time is 5 days. MRP flags the shortage, suggests a PO, and you approve it with one click. The PO goes to your preferred vendor at negotiated pricing. When it arrives, receiving logs it against the PO, and inventory updates automatically.
Vendor management
Tracking which vendors supply which materials, their pricing, lead times, and quality history helps you make better purchasing decisions. Over time, you build a picture of vendor reliability that informs both purchasing and quoting — if a vendor is consistently late, you pad the lead time in your schedule.
