A vendor onboarding checklist template is worth about fifteen lines, and most published ones run to sixty. The long ones are written for organisations with procurement staff, and in a firm without them the extra lines are not completed, which quietly teaches everyone that unticked lines are normal. This page gives the compact version, says what to delete, and describes how to keep it current without it growing back.
The compact list
Legal entity and taxpayer identification details. Remittance and invoicing instructions. A contact for the work and a contact for invoices. Required evidence with its expiry. Approval recorded with the budget holder named. Setup in your payment system and in whatever access the relationship needs. Confirmation that the vendor is payable. That is the list, and every line is something a person does and can tick.
What to delete from enterprise templates
Anything requiring a scoring model, a tender comparison, a risk tier or a quarterly review cycle. Those need a function to run them. Delete them rather than leaving them unticked: an unfinished checklist and an absent checklist look the same to the person relying on it, but the unfinished one costs you the credibility of the whole list.
Keeping it from growing back
Add a line only when the same gap has caused a problem twice, and require the person adding it to name what it replaces once the list passes about twenty rows. Both rules are deliberately slow, because vendor checklists grow by accretion after individual bad experiences and shrink only by deliberate decision.
Sizing it honestly
Count your lines and the documents you request, multiply by the vendors you take on in a year, and the checklist has a cost in hours. The free worksheet on this site does that from your own numbers. It is the same arithmetic as for clients because it is the same work, done by the same person, on a different counterparty.
Questions people ask about vendor onboarding checklist template
How is this different from the vendor onboarding form?
The form is what the vendor fills in. The checklist is what your firm ticks, and it includes several steps the vendor never sees.
Does every line need an owner?
Yes. A line with no owner is the one that is still outstanding a month later.
Can we reuse the client onboarding checklist?
Largely. Most firms keep one checklist whose identity and payment blocks are shared and whose middle section swaps by counterparty type.
