Status Tracker · 8 onboardings, one vendor, business days to approved-supplier status
The mean says 7.4 days. Six of eight buyers say 4.
| Read | Days |
|---|---|
| Median across all 8 onboardings | 4 |
| Mean across all 8, as they actually happened | 7.4 |
| Mean if both blockers below were already in the register | 3.9 |
The two that were not four days
| Buyer | Days | Blocked on |
|---|---|---|
| Aldgate Manufacturing | 16 | Certificate naming them specifically as additional insured |
| Kestrel Health Systems | 20 | Signed bank letter, nothing already on file |
Both documents exist in the register today. The next buyer who asks for either one gets a four-day onboarding instead of a sixteen or twenty-day one.
Search this and every result is written for the other side of the table. A vendor onboarding form template tells a buyer's procurement team what to ask a new supplier for: legal name, tax ID, a W-9 or W-8, banking details, a certificate of insurance. A checklist adds the review step: confirm the certificate names the buyer correctly and the W-9 matches the contract's entity. All of it assumes the reader collects the form. None of it addresses the vendor filling in a different one of these every time a new buyer signs.
Filling one in is not the hard part. Across eight onboardings for one vendor, six cleared in three to five business days. The other two took sixteen and twenty, both for the same reason: one document, an endorsement or a signed bank letter, was not ready when the form asked for it. The mean across all eight is 7.4 days; strip out those two and it drops to 3.9. A request for a completed W-9 resolves in minutes once the information is on file; the document with more than one shape is what stalls this.
Built for whoever answers these forms on the vendor's side, usually in finance or revenue operations, once the mutual action plan has run its course and signature logistics are settled. A request naming a dollar limit or an endorsement your policy does not actually carry is a different problem, checked in the insurance and certification evidence pack instead. This pack assumes the documents are good and gets them into the specific shape each buyer's own process will accept.
What's in the pack
Check the Register First
The method itself: read the standing register's status and date before answering a single field on a new buyer's onboarding form.
Document Register sheet
Every standing document you hold, tax, insurance and banking, with a status and a date, kept current before a buyer ever asks.
Requirement Checklist sheet
What each buyer's own portal or form actually asks for, mapped back to the same underlying facts every time.
Status Tracker sheet
How many business days each onboarding actually took, with the specific document named when one held it up.
Completed Form Set doc
The record of exactly what went back to one buyer: every document attached and every field typed by hand, with the version and date on each.
Process Note doc
What made one onboarding run long against the median, and what changes before the next buyer built the same way shows up.
How it works
- 1
Load the register
Whatever you already hold: a W-9, a certificate of insurance, the last confirmed banking details, current or not.
- 2
Bring one buyer's form
A portal checklist, a PDF, an email from accounts payable, in whatever shape it actually arrived.
- 3
River matches the two
Answers what the register already covers, and names exactly what does not match the shape this buyer's process wants.
- 4
Fix the gap, not the whole packet
Only the flagged item goes back to a broker or a bank. Everything else in the packet was ready before the form arrived.
Frequently asked questions
Is this template free?
Yes. Two Word documents and three CSV sheets, downloaded as a zip, no signup. River is the optional half: it reads the register, matches it against a buyer's actual form, and names exactly what still needs sourcing.
Why do supposedly quick onboardings sometimes take three weeks?
Because one document was not already in the shape this specific buyer's process needed. In the tracked sample, six of eight onboardings cleared in three to five days; the other two ran sixteen and twenty, each blocked on a single item nobody had sitting ready.
Isn't a blanket additional-insured endorsement enough for every buyer?
No. Some regulators address this directly: a certificate can state that a blanket endorsement exists, but it cannot name a specific holder unless the endorsement itself names them. A minority of buyers check for their own name and will send the blanket version back.
How is this different from a security or insurance evidence tracker?
That register checks whether a document you hold clears the specific dollar limit or endorsement a request names. This one assumes the documents are already good and gets them into whichever format each buyer's own onboarding process will accept.
What if a buyer asks for something the register doesn't cover yet?
It gets logged as a new candidate rather than answered once and forgotten. A state-specific license or a diversity attestation that shows up on one buyer's form is worth adding permanently if the kind of buyer asking for it is likely to reappear.
Does this replace the mutual action plan or the signature checklist?
No. The mutual action plan plans the path to signature and deliberately leaves this register out of it. Signature logistics covers who has to sign. This space starts once a buyer's own vendor setup shows up, before or after either one.
