How long should supplier onboarding take?
The neutral benchmark is a median of three days. Laggards take weeks of forms and chasing — and the cost of those weeks is not administrative. It is that busy, capable subcontractors quietly decide not to bid, and nobody ever tells you that is what happened.
The cost is invisible, which is why it persists
A slow onboarding process does not announce itself. No subcontractor writes to say “your registration form was too long, so we declined your enquiry.” They simply do not respond, and the enquiry closes with three bids instead of five, and somebody notes that coverage was thin this time.
The subcontractors most likely to walk away are the ones with the most work on — which is to say, the good ones. Onboarding friction is a filter, and it is calibrated to remove exactly the firms you wanted.
What thin coverage actually costs
Awards made on two bids are not competitive. They are a coincidence with a paper trail. And the pricing consequence is real: the evidence on bidder pools is that a properly contested tender of four to six genuine bidders produces materially better pricing than a thin one, which is the whole reason anyone tenders at all.
So a registration form with sixty fields is not an administrative preference. It is a decision to pay more for your subcontract packages, taken by somebody who did not know they were taking it.
What good looks like
Self-registration, so the vendor enters their own data — including their own bank details, which they know and you are guessing at. Under about fifteen fields to get started, with the rest collected when it is actually needed.
Then validation by procurement in minutes rather than a week of email. And phone-supported onboarding for the strategic trades you genuinely cannot afford to lose. Three days is achievable. Weeks is a choice.
