If your organization hires construction or maintenance contractors, AP has a job that has nothing to do with the invoice in front of it: confirming the contractor's insurance is current before any payment goes out.
For property-management and public-housing finance teams, this isn't optional. A contractor performing work on housing units is required to carry — and prove — construction insurance. No valid certificate of insurance, no payment. The certificate is a gate on the entire payment, not a piece of paperwork to file afterward.
The trouble is that certificates and invoices arrive through the same channel, get mixed together, and then live in places AP can't easily check at pay time.
Why this breaks in most AP setups
Certificates of insurance tend to fall into the gaps of an invoice-centric workflow:
- They arrive mixed in with invoices. A contractor emails their bill, and the certificate is one of several attachments on the same message. Auto-classifying which PDF is the invoice and which is the insurance certificate is genuinely hard to get right every time — the layouts vary, and a misfile means either a blocked payment or, worse, a payment that shouldn't have gone out.
- They belong to the supplier, not the invoice. A certificate covers a period, not a bill. Attaching it to a single invoice loses that. The next invoice from the same contractor needs the same proof, and re-hunting for it is wasted effort.
- Coverage expires. A certificate that was valid in January says nothing about whether the contractor is covered in June. AP needs to know the current state at the moment of payment, not whatever was true when the certificate first arrived.
A workflow that actually holds the gate
The pattern that works leans on a deliberate piece of human judgment at exactly one point, then automates everything around it.
- Process the certificate like an invoice — then mark it. Because reliably auto-separating certificates from invoices isn't foolproof, the cleanest approach is to let a certificate flow in through the normal capture path, then give the AP user a one-click option on the data-entry screen to mark the item as an insurance certificate. That single human decision removes all the ambiguity.
- Assign it to the right supplier. When an item is marked as a certificate, the user specifies which supplier it belongs to, with existing suppliers auto-suggested so the match is fast and consistent. The certificate is now tied to the vendor, not to one invoice.
- Store it on a supplier-level certificates page. Certificates live in a dedicated per-supplier area where AP can preview current coverage and remove superseded documents. The next invoice from that contractor inherits the same coverage context automatically — no re-hunting.
- Carry it through to approval and the ERP. When an invoice is approved, the associated certificate can travel with it — passed through the integration or included in the export file — so downstream systems and auditors see the proof of coverage alongside the payment.
The key design decision is attaching at the supplier level, not the invoice level. Coverage is a property of the vendor relationship over time. Modeling it that way means one certificate covers every invoice in its period, expirations are visible in one place, and AP can answer "is this contractor currently insured?" without opening five old invoices.
Why a public entity needs this to be airtight
For a housing authority spending public funds, paying a contractor whose insurance has lapsed is a real liability exposure, not a clerical slip. The certificate gate has to be reliable, auditable, and impossible to skip by accident. Storing certificates against the supplier — where they're easy to preview, easy to keep current, and automatically in scope for every future invoice — turns a fragile manual check into a standing control.
Where EZ Cloud fits
EZ Cloud captures multiple attachments off a single supplier email, lets your AP team flag any item as an insurance certificate with one click, and stores it on a per-supplier certificates page where coverage is previewed, kept current, and carried through to approval and export. The certificate gate lives inside the same workflow as the invoice, so it can't be quietly bypassed.
A US housing authority uses this exact pattern to manage construction-contractor coverage in production — the broader story is in our HACOV case study, and how this connects through to Yardi Voyager is on our Yardi integration page.
If your AP team is chasing certificates of insurance through old email threads to decide whether a contractor can be paid, moving that proof to the supplier level is the fix. It's a small modeling change with an outsized effect on both speed and risk.
