Supplier Audit Checklist: 10 Metrics That Predict Reliability
Skip the theatrical factory tour. Audit these 10 concrete, observable metrics instead — they correlate with on-time delivery and consistent quality far better than impressions.

Why metrics beat impressions
Factory audits fail when they become show-and-tell: the clean showroom, the smiling sales manager, the empty production floor. A useful audit is an evidence check — you are looking for systems and records that produce consistent results even when no one is watching.
The ten metrics below are ordered from easiest to verify to hardest, so a desk audit and a site audit use the same framework. Score each 0–10 and set your own pass threshold (most buyers use 70/100 for a first order).
The ten metrics
1) Legal identity — license, export rights, registered address match the contracting entity. 2) Financial health — bank statements, credit reports, or willingness to accept L/C. 3) Certifications — ISO 9001 plus market-specific certificates, valid and covering the product. 4) Production capacity — equipment list, line utilization, and whether current orders match stated capacity. 5) Quality control — incoming inspection, in-line QC, final QC with documented rejection rates.
6) Traceability — batch numbers, material certificates and production records that can trace a finished unit back to its inputs. 7) On-time delivery history — ask for recent shipment records and check them against promised dates. 8) Communication — documented response times, English fluency of key staff, and whether reports are proactive or demanded. 9) Social compliance — labor contracts, working hours, factory safety (fire exits, PPE). 10) Financial terms flexibility — willingness to offer progressive payment, escrow or L/C instead of insisting on 30% prepayment.
Conducting the audit
Announce a date but keep a few items for the unannounced follow-up: capacity and workforce are easy to stage for a planned visit. Take photos, keep the scoring sheet, and get the factory manager to sign the audit summary — a signed record is a negotiation asset later. For remote audits, use a live video call with a checklist and request real-time footage of specific workstations.
Questions fréquentes
Are remote audits as good as on-site audits?
Remote audits verify documents, records and systems well, and live video can cover much of the physical check. They are weaker at verifying workforce size, real production activity and warehouse stock — the areas most commonly staged. For first orders under ~USD 10k, remote is usually proportionate; above that, budget for an on-site or third-party audit.
How often should I re-audit a supplier?
A common cadence: full audit annually, plus a lighter 'health check' (shipment records, quality trends, communication metrics) every 3–6 months. Re-audit sooner if quality rejects rise, delivery slips, or the supplier changes ownership or key staff.
What if the supplier fails the audit?
Share the scored checklist with the supplier and ask for a written corrective action plan with deadlines. Many factories genuinely improve with structured feedback. If they argue, dismiss the findings, or refuse to share records, treat that as the audit's real finding — reliability will not improve after the order is placed.
