Reverse auctions
Vendors bid down against a live clock. Rank, best price and time remaining update as bids land, with auto-extension so the last seconds are never a lottery.
Enterprise sourcing, without the spreadsheet
Procurement that closes on time.
Run reverse auctions, sealed bids and vendor onboarding in one place. Every bid is timestamped, every award has a trail, and nothing lives in an inbox.
Built to run on Cloudflare’s edge — no servers to babysit.
Everything a sourcing event needs
eProc is deliberately narrow: it handles the auction, the bids and the award. It does not try to be your ERP.
Sealed bids
For topline and technical rounds, bids stay hidden until the window closes. Nothing is revealed early, including to the buyer.
Vendor onboarding
Invite vendors per event, collect the documents you need, and keep the same vendor record across events instead of re-verifying from scratch.
Bid comparison
Line-item and landed-cost views side by side, so an award decision is based on the numbers rather than the loudest vendor.
Audit trail
Every login, bid and status change is written to an append-only log. Useful in a review, essential in an audit.
Roles and access
Buyers, approvers and vendors see only what their role allows, with vendor accounts scoped to their own organisation.
How it works
-
Set up the event
Pick the type — reverse auction or sealed bid — add line items, set the window and choose the vendors who are invited.
-
Invite the vendors
Each vendor gets scoped access to just that event. They see their own bids, the clock and their rank — never a competitor’s numbers.
-
Award with evidence
Compare, record the reason and close the event. The trail of who bid what, and when, is already written.
Built for a short list, not the whole internet
eProc is sized for focused programmes — a handful of enterprises, each with ten to twenty active vendors — rather than open public tendering.
That choice keeps the product sharp and the security model simple: fewer accounts, tighter scoping, and no anonymous bidding.
- Signed, server-side sessions — no tokens in local storage
- Tenant isolation enforced in the data layer, not in the UI
- Append-only audit log written outside the main database
- No third-party analytics or ad scripts on the app
- Passwords stored with a slow hash and per-user salt
Questions buyers ask
Can vendors see each other’s bids?
In a reverse auction a vendor sees its own rank and the best price — never who else is bidding. In a sealed bid nothing is visible until the window closes.
Does it replace our ERP or contract management?
No. eProc covers the sourcing event: setup, bidding, comparison and award. Purchase orders, invoicing and contracts stay where they already are.
How many vendors can one event handle?
Events are designed around ten to twenty invited vendors. If you need open public tendering with hundreds of participants, eProc is the wrong tool and we would rather say so.
Where is the data stored?
In Cloudflare D1, with audit records in R2. Both stay within the region configuration of the deployment, and nothing is copied to a third-party analytics service.
