3PL Services Tips #6 – Rich Boland, Client Services, Precision Group
The friction point that stops many businesses moving forward isn’t cost it’s the fear of disruption. ‘Switching sounds hard. What actually happens during 3PL onboarding?’ A good onboarding process is a controlled transition not a single event. Here’s what it looks like when done properly.
The five workstreams of 3PL onboarding
- Commercial and scope alignment (SLAs, pricing, peak rules)
- Data readiness (SKU master data, barcodes, dimensions, pack rules)
- Systems integration (API/file flows, order rules, shipping labels)
- Inventory transfer and warehouse set-up (receipting, putaway, slotting)
- Go-live and stabilisation (test orders, exception management, KPI cadence)
Rush any one of these and costs rise — through errors, missed cut-offs, and support load.
Phase 1: Kick-off and discovery
Agree on order types, dispatch rules, exception handling, and responsibilities. You should receive a written onboarding checklist, an operational SOP outline, and a data template for SKUs, barcodes, and pack rules.
Phase 2: Data readiness (this is where onboarding succeeds or fails)
You need to provide SKU master data, unit and carton dimensions, pack rules (fragile, inserts, returns rules), and lot/expiry requirements if applicable. A good 3PL validates your file for duplicates, missing barcodes, and inconsistent naming before a single item is receipted.
Phase 3: Integration
Minimum viable integration: daily order import, dispatch confirmations with tracking, and basic inventory updates. Best practice: near real-time sync with exception states fed back to your eCommerce platform. Ask what happens if the integration fails on a high-volume day.
Phase 4: Inventory transfer
Three parts: physical movement plan (who transports it, what happens to orders during transit), receipting and baseline count (never assume your count is correct), and slotting (fast movers accessible, variants separated to reduce look-alike errors).
Phase 5: Testing
Test at least 10–30 orders across your main order types before go-live including returns, split shipments, backorders, and orders to different zones. Testing is the cheapest time to find problems.
Go-live: soft launch beats big bang
Start with one channel or product range, stabilise for 1–2 weeks, then add complexity. Your 3PL should provide daily exception reporting, a clear escalation path, and a brief daily check-in for the first few days.
