Distribution ERP: Demo Scenarios Vendors Must Prove
A distribution ERP should prove that it can keep availability and customer promise dates reliable despite shortages, priorities, returns, pricing rules, EDI exceptions and inter-site transfers. Test real exceptions, not only the happy path.
Structure my ERP selectionThe scenarios the ERP must prove
- Availability and promising. Show actual stock by site, reservations, inbound supply and what can truly be promised to a customer.
- Pricing. Test customer, contract, quantity, promotion, rebate and exception rules actually used.
- Warehouse. Receiving, put-away, picking, packing, shipping and variance handling must work at operational speed.
- EDI and channels. Orders, confirmations, ASNs, invoices, ecommerce and marketplaces must handle rejects and recovery.
- Returns. RMA, inspection, restocking, credit and financial impact must remain in one coherent workflow.
- Multi-site. Transfers, in-transit stock, replenishment and consolidated visibility must be demonstrated.
What matters most in the selection
- Reliable availability. Physical, reserved, in-transit and promised inventory should tell the same story.
- Governable pricing. Contracts, rebates, promotions and exceptions should remain understandable and auditable.
- Warehouse execution. WMS, barcode, picking and shipping flows must hold up at real volume.
- Robust EDI. Rejects, recovery and statuses should be visible without manual investigation.
- Returns and margin. A return should update inventory, credit, cost and margin correctly.
- Multi-site operations. Allocation, transfers and replenishment must work across branches and warehouses.
What the ERP must avoid making worse
- Ghost inventory. The system shows stock as available when it cannot actually be promised.
- Opaque pricing. Rules live in manual exceptions that are difficult to audit.
- Fragile EDI. Rejected documents require off-system intervention and manual follow-up.
- Disconnected WMS. Warehouse activity reaches the ERP too late.
- Inconsistent returns. Inventory, credit and margin do not reconcile automatically.
- Peak volume never tested. The workflow looks fine in a demo but slows when real volume arrives.
The flows to validate before choosing
- WMS and warehouse automation: movements, locations, picking, packing and shipping.
- Customer and supplier EDI: orders, confirmations, ASNs, invoices, rejects and recovery.
- Ecommerce and marketplaces: orders, availability, statuses, pricing and returns.
- TMS and carriers: rates, labels, tracking, proof of delivery and freight cost.
- CRM, contracts and rebates: pricing rules, programs, commissions and promotions.
- BI and planning: availability, turns, margin, service levels and forecasts.
Questions to answer before the shortlist
- Which order flows represent the greatest operational risk?
- Which pricing and rebate rules must be maintained without manual intervention?
- Will the WMS remain in place, and which system owns each data element?
- Which EDI partners and rejection scenarios must be tested before selection?
- How does the solution protect shipments during peak volume and production cutover?
- How do returns update inventory, credit, cost and margin?
Do not ask the vendor to show its best workflow. Give them your exceptions: scarce stock, a rush order, contract pricing, an EDI rejection, a return and an inter-site transfer.
