Supplier Onboarding Checklist: How to Set Up New Suppliers Correctly From Day One

The cost of poor supplier onboarding#

You onboard a new supplier without capturing their preferred payment terms. First invoice arrives net 45, but you assumed net 30. Payment dispute consumes 4 hours of time. You don't have their tax ID, so you cannot set up payment processing. Invoices are paid manually instead of automatically, doubling processing cost. You don't have insurance/compliance certificates on file, so you scramble to collect them last-minute when an audit happens. Over a 3-year supplier relationship, poor onboarding creates recurring friction: payment delays, compliance gaps, contact confusion, and quality misunderstandings. Total cost: SGD 15K-30K in operational friction, compliance risk, and management time.

The supplier onboarding checklist#

Supplier identification: legal name, business registration number, tax ID, country of incorporation. Contact information: primary contact (name, email, phone), backup contact, payment inquiry contact, quality/technical contact. Bank details: bank name, account number (in supplier's home currency), SWIFT code or equivalent, any special payment instructions. Payment terms: net 30/60/90, early payment discounts (if any), currency of invoicing, invoice format preferences. Shipping and logistics: preferred freight forwarder, standard shipping method (air/sea/sea+land), insurance requirements, delivery address confirmation. Quality and compliance: quality certifications (ISO, specific product certifications), insurance (liability, quality), product compliance documentation (safety, environmental), audit/inspection frequency.

Legal and compliance verification#

Ensure the supplier is a registered, legitimate business: verify business registration in their home country, check for any sanctions or compliance flags using a sanctioned parties list (if international supplier), obtain D&B or equivalent credit check, collect proof of insurance (general liability, product liability), and obtain signed NDA if handling confidential specifications.

Communication protocols and escalation#

Establish: weekly communication rhythm (call, email cadence), order placement process (how you will submit POs), order acknowledgement process (how supplier confirms receipt and timing), status update frequency (how you will track progress), and escalation protocol (if there is a problem, who do you contact first).
