What is Purchase Order Management?
Purchase Order Management governs how requests turn into approved POs, how suppliers confirm and deliver, and how invoices reach payment. Get this loop right and you gain visibility, control, and clean audit trails across vendors and locations. It fits naturally alongside Tejas’ OMS/WMS suite (“Fulfillment Made Easy”).
See myPOmanager -Tejas Purchase Order Management System (rule-based automation, EDI/API, dashboards).
How does the PO management process work?
Here’s the lifecycle many teams adopt:
- Requisition
- Vendor selection and terms
- PO creation
- Approvals & tolerances
- Dispatch to supplier (email or EDI/API)
- Order tracking (confirmations, ASN, delivery)
- Goods receipt (GRN)
- Payment & reconciliation
- Reporting & continuous improvement

Stage-by-stage purchase order workflow
Vendor Shortlisting
- Use standard item masters, lead times, and SLAs.
- Capture MOQ, price tiers, and promised ship windows.
Tip: Keep a supplier scorecard for OTIF and defect rates.
PO creation (fields that matter)
- Item, quantity, price, tax; ship-to; incoterms; cancel-by date; payment terms; routing notes.
- Numbering scheme and version control for change orders.
- In Tejas’ myPOmanager, rules help suggest what to buy based on sales velocity and seasons.
Approvals & tolerances
- Set thresholds by spend, category, or vendor risk.
- Auto-approve within tolerances; route exceptions to owners.
- Role-based notifications keep cycles short.
Sending POs to Suppliers
- Use email for small suppliers; prefer EDI/API for speed and fewer errors.
- Capture acknowledgments and change requests in one thread.
Tracking status & delivery
- Expected ship date, ASN, last-mile updates.
- For retail/ecom, sync with OMS (TOMS) and WMS (TWMS) for real-time promise dates and receiving slots.
Goods receipt & discrepancies
- Partial receipts, damages, and returns handling.
- TWMS supports putaway, bin rules, and mobile scans for fast receiving.

Field-tested procurement best practices
- Standardize item data and vendor terms; apply tolerance bands for price/qty.
- Maintain scorecards for OTIF, quality, and responsiveness; review in QBRs.
- Use contract pricing and planned buys for top movers; keep buffers for long-lead items.
- Sync inventory plans with OMS & WMS so buys match realistic demand and receiving capacity.

Common challenges in Purchase Order Management (and fixes)
- Maverick spend: lock catalog + approvals; surface preferred vendors in the PO screen.
- Change orders: version every PO; capture deltas; notify stakeholders automatically.
- Late receipts: tie vendor ASN to WMS receiving slots; escalate by rule.
Do I need integrations for my purchase order workflow?
Yes. Your Purchase Order Management setup should “speak” OMS, WMS, ERP, finance, and notifications. That reduces re-keying and aligns buys with real demand and storage. Tejas provides prebuilt connections across TOMS, TWMS, and finance stacks.

Tejas in action
A UK fashion retailer implemented Salesforce Order Management alongside Tejas WMS, with complex pick/pack flows, dashboards for staff efficiency, and rate shopping integrations. Timelines: Salesforce OM ~5 months; Tejas WMS ~3–4 months, including MuleSoft and NetSuite ties in other programs—evidence that modern stacks reach value quickly when scope is clear.

FAQs
What is Purchase Order Management and why use it?
It’s the framework that turns requests into approved POs, receives goods, matches invoices, and closes payment with audit trails. Done right, the purchase order workflow brings control, visibility, and cleaner books.
Where should purchase order automation start?
Begin with threshold-based approvals and supplier EDI/API for confirmations, then add 2/3-way invoice matching and exception queues. This sequence delivers quick wins without disruption.
Which KPIs matter for the PO management process?
Focus on PO cycle time, first-pass match rate, price variance, OTIF, and late-payment rate. Review them in dashboards and tie actions to owners, not committees.
How do integrations improve purchase order management?
Connecting POs to OMS, WMS, ERP, and AP removes re-keying and syncs buys with real demand and receiving capacity. It also shortens dispute cycles and clarifies cash impact.
How should teams handle supplier disputes or mismatches?
Version the PO with evidence, route exceptions to the Approver, and make the Buyer accountable for resolving issues with the supplier. Place holds only on affected lines, keep communication in a single thread, and track closure SLAs.
