Switching corporate-merch supplier — migration guide
Step-by-step guide to switching your corporate merch supplier without service disruption: timing, contract review, knowledge transfer, dual-running.
When to switch
Common triggers: declining quality (defect rate > 1.5%), missed delivery dates (>5% of orders late), sustainability documentation gaps (no current EcoVadis), uncompetitive pricing (>15% above market), poor responsiveness, or strategic mismatch (geographic / vertical fit).
Pre-switch audit
- Pull 12 months of order data (quantity, defect rate, OTD, total spend)
- Review current contract: notice period, IP transfer, residual obligations
- List in-flight orders + their delivery dates
- Inventory any vendor-held tooling (silkscreen frames, embroidery digi files, dies)
- Document brand assets the current supplier holds (Pantone refs, master files, sample library)
Migration timeline (12 weeks typical)
| Week | Activity |
|---|---|
| 1-2 | RFP issued to 2-3 alternative suppliers |
| 3-4 | Scorecard review, finalists selected, references checked |
| 5 | Pilot order with finalist (50-200 units) |
| 6-7 | Pilot QC review, contract negotiation |
| 8 | Contract signed; notice given to outgoing supplier |
| 9-10 | Knowledge transfer: artwork files, color refs, digi files, sample library |
| 11-12 | Dual-running: outgoing finishes in-flight, new supplier ramps up |
Knowledge-transfer checklist
- Pantone color profiles per SKU
- Approved artwork files (vector + raster)
- Embroidery digi files
- Silkscreen films / mesh specs (if proprietary)
- Sample library (3 production samples per SKU)
- Audit history (defect reports, AQL records)
- Compliance docs (EcoVadis, Sedex, OEKO-TEX certificates)
- Forecast / volume plan
- Recipient personalization data templates
Common migration risks
- Color drift between old and new supplier — require sample sign-off before bulk run
- Lead-time gap during cutover — overlap by 4-6 weeks to avoid stock-outs
- Lost tooling at outgoing supplier — recover or rebuild at new supplier (budget for rebuild)
- Recipient confusion if branding shifts subtly — define ΔE tolerance in new contract
- Audit-document gaps — verify new supplier's current certs before signing
