Collecting W-9 Forms From Vendors
Ask for it in the questionnaire, not in an email
The W-9 is almost never the difficult part. Requesting it separately, after the vendor thought they had finished, is what turns a two minute task into three weeks of follow-up.
It is a sequencing problem, not a document problem
Everyone knows which vendors need a W-9. The delay comes entirely from asking for it after the vendor has mentally finished with you.
The form arrives with the submission
Making it an upload question inside onboarding means the vendor provides it while they are already engaged rather than weeks later.
The right vendors are asked
Branching shows a W-9 to US entities and a W-8 to foreign ones, so nobody is asked for a form that does not apply to them.
Nobody files it by hand
The document is read on arrival and placed against the vendor record, so finance can find it without asking procurement.
The email route against the form route
The difference is not effort, it is timing. Asking during onboarding costs nothing extra.
After onboarding
The vendor completes the questionnaire, then somebody notices the tax form is missing and starts an email thread.
During onboarding
The upload sits alongside the questions it belongs with, so it arrives as part of the submission.
Both, to everyone
US and foreign vendors are asked for the same set, so half of them are confused and some submit the wrong one.
Branched by entity type
A W-9 for US entities, a W-8 for foreign ones, shown based on how the vendor answered.
Saved by a person
Somebody downloads the attachment and saves it somewhere, which means finding it later depends on their convention.
Filed automatically
Read on arrival and placed against the vendor record alongside their answers and score.
The whole form again
A change of entity details triggers a full re-onboarding, which vendors resist and often do not complete.
Only the form that changed
The tax form is requested on its own with everything unchanged carried forward.
