How long should supplier onboarding take before I can use a new supplier on a live job?

For standard stock items, one qualification order cycle is typically enough: place the order, receive and verify the delivery, check the invoice, and log the outcome. That can be completed in one to three weeks for most categories. For suppliers of bespoke goods or time-critical services, run at least two qualification cycles before relying on them for a job with a firm deadline.

Do I need a formal supplier agreement or is email sufficient?

A formal supplier agreement gives you stronger contractual protection, but it is not always practical for every supplier relationship. At a minimum, get the damage claim window, returns policy, and lead time commitment confirmed in writing by email before the first order. For high-value or recurring suppliers, a formal written agreement is worth the time it takes to set up.

Workflow Scenario

Procurement - Onboarding a New Supplier

7 steps. One qualified supplier. No surprises.

Step by step

Collect Supplier InformationPurchase Orders

Gather legal trading name, registered address, VAT number, primary and billing contacts, payment terms, bank details, and certifications in writing before any order is placed.

Confirm Operating RequirementsRFQs

Get lead time commitment, minimum order quantities, damage claim window (48-72 hours), returns policy, and any exclusivity restrictions confirmed in writing.

Place Qualification OrderPurchase Orders

Place a small, low-risk order on standard stock lines before committing the supplier to a high-value or deadline-critical job. Tests acknowledgment, lead time, packaging, and invoicing.

Raise Formal POPurchase Orders

Issue a full purchase order with product codes, agreed price, delivery date, payment terms, and job reference. Establishes the price baseline for three-way matching from the first transaction.

Inspect DeliveryDelivery Notes

Count against the delivery note, check product condition, verify specifications. Log discrepancies immediately and notify the supplier in writing within the agreed claim window before approving the invoice.

Complete Qualification ReviewJobs

After the first invoice is paid, review order acknowledgment speed, lead time accuracy, delivery completeness, and invoice accuracy. Record outcome and decide whether to advance to preferred supplier status.

Add to Preferred Supplier ListPurchase Orders

Record the supplier with category, tier (primary or secondary), agreed pricing, lead time commitment, and review date. Set a 90-day performance check reminder.

What this workflow solves

A new supplier was placed on a high-value job without a qualification order, and the first delivery arrived short with no agreed claim process to fall back on.

The first purchase order was raised verbally and the supplier invoiced at a higher price than quoted, with no written PO to dispute it against.

After a spot purchase went well, the supplier was assumed to be reliable but never formally added to the preferred list, so the same qualification gap appeared six months later.
