Your ERP records the purchase. VEXORS wins it.
The ERP raises the purchase order, matches the invoice and posts the ledger, once a supplier is chosen. Everything before that (finding suppliers, collecting comparable bids, scoring them, defending the award) still happens in inboxes and spreadsheets. That is the gap VEXORS fills, with zero data migration and nothing ripped out.
No card to start. Your first request goes out in minutes.

What is the difference between an ERP purchasing module and a sourcing platform?
An ERP purchasing module raises the purchase order, matches the invoice, and posts the payment, once a supplier has already been chosen. A sourcing platform runs the step in front of that: publishing the request, inviting bidders who are not yet vendors, collecting bids on the same scope, answering clarifications, levelling and scoring the responses, and keeping the record behind the award. VEXORS is the sourcing platform. It hands the ERP a supplier and a price to act on, and the ERP keeps doing everything it already does.
A purchase order and a sourcing decision answer different questions
One is who should win the business, and the other is how to record that a winner was chosen. An ERP purchasing module answers the second question well, not the first.
Before the award, on VEXORS
- Find suppliers beyond the vendor list, with AI matching suggesting companies from the network that fit the request.
- Structure the request as an RFQ, RFP, or RFI, drafted by AI from a plain description, with line items and criteria you refine before publishing.
- Collect bids against those same line items, so every response lines up for comparison.
- Score the bids with AI and a written rationale for each score, then decide. The buyer always makes the call.
After the award, in the ERP
- Raise the purchase order against the supplier and price the buyer chose.
- Match the invoice against the PO and what was actually received.
- Post the transaction to the ledger.
This is the job SAP, Oracle, and Microsoft Dynamics purchasing modules are built for, and VEXORS leaves it exactly where it is. Nothing gets ripped out. The ERP keeps doing what it has always done. VEXORS runs the step in front of it.
One system of record, one system that wins the business
The ERP stays the single place purchase orders, invoices, and payments live. VEXORS runs the step before that record exists: the request, the bids, the scoring, and the reasoning that produced the number the ERP eventually posts.
Zero data migration
Nothing moves out of the ERP, and nothing has to. VEXORS runs alongside SAP, Oracle, Microsoft Dynamics, or Odoo; the vendor master, the chart of accounts, and every posted transaction stay exactly where they are today.
Live before your next purchase order
There is no implementation project to schedule. Your first structured RFQ, RFP, or RFI can go out the day you sign up, on the free Explore plan, while the ERP keeps running the postings it already handles.
What the module cannot see
Invite bidders who are not vendors yet
The vendor list holds who the company already buys from. There is no field in it for a supplier that has not been entered yet, so finding one happens outside the ERP entirely. On VEXORS a supplier does not need to exist in your system before you invite it: it registers free from the invitation itself and prices the request in a browser or on a phone. AI-assisted matching can also suggest companies from the network that fit the request, mentioned here only as an option; your own invited list stays private to you and is never shown to the suppliers you compare.
- Suppliers register free from your invitation, with no procurement account required first.
- The buyer's invited bidder list stays private and is never shown to the suppliers being compared.
- Your existing approved vendors can be invited alongside anyone new, in the same request.
- AI-assisted matching can suggest additional companies from the network that fit the request.
Bids that line up because they answer the same request
A purchase order module records one supplier and one price. There is nowhere in it to place a competing bid next to that one, so the comparison happens in a separate spreadsheet, or does not happen at all. A VEXORS request carries its own line items, quantities, and criteria, and every bidder answers against those same lines, so the responses arrive already lined up instead of arriving in whatever format each supplier chose. The comparison exports to Excel if that is where the decision gets reviewed, and it supports more than one currency when bidders quote in different ones.
- Requests are structured as an RFQ, RFP, or RFI, with line items and evaluation criteria set before publishing.
- Every bid arrives in the structure of the buyer's own request, so responses are comparable at the deadline.
- The comparison exports to Excel for whoever reviews the decision outside VEXORS.
- Each request runs in the currency you set, and every bidder quotes in it.
Clarifications, answered once, published to everyone
A purchasing module has no field for a question a bidder asks before pricing the line. On VEXORS, a bidder asks inside the request, the buyer answers once, and that answer is published to every other bidder at the same time, so nobody prices a request on an assumption someone else was corrected on. The bidder who asked is never named to the others. If the request itself changes, the revision reaches every bidder at once, and a bid still priced on the old version is flagged before it is compared.
- A bidder's question and the buyer's answer go to every other bidder, not just the one who asked.
- The asker's identity is never shown to the other bidders.
- A revision or addendum reaches every bidder at the same time.
- A bid priced on a version before the latest revision is flagged automatically.
Levelled before it is ranked
The lowest number as submitted is not always the lowest bid. An item a bidder left unpriced is counted and priced back in at the buyer's own estimate or the median of the other bids for that item, so a bid that looks cheapest only because it left the most out does not win by default. A section priced as a declared lump sum still counts as priced; only a silent gap gets added back. On every item with at least three prices, a rate far from the others is flagged with how far off it is, so an unusually low or high line gets a second look before the total is trusted.
- Unpriced items are added back at the buyer's estimate or the median of the other bids for that item.
- A declared lump sum counts as priced; only a silent gap is priced back in.
- A rate far from the median on any item with three or more prices is flagged with its ratio.
- Bids are ranked on the levelled total, not the total as submitted.
Every score has a reason, and the file remembers why
There is no field for what a bid was measured against. When finance asks why that supplier won, the answer has to be rebuilt from memory or an old email thread. On VEXORS every bid is scored out of 100 against the buyer's own commercial and technical criteria, weighted the way the buyer sets it, with the reason written beside each score. AI recommends a bid; the buyer still makes the call, and the approval is recorded by name. The scores, the reasons, the revisions, the questions and answers, and the named approvals all stay with the tender, so the answer is on file instead of in someone's memory.
- Bids are scored out of 100 against the buyer's own commercial and technical weights.
- AI recommends a bid and writes the reason beside each score; the buyer decides.
- Approvals are recorded by name against the award.
- Scores, reasons, revisions, and questions and answers stay with the tender as one record.
A purchasing module was never built for these four jobs. Every one of them is costing you today.
The ERP module alone vs. VEXORS in front of it
Finding a new supplier
- ERP purchasing module alone
- Only vendors already in the master list
- VEXORS
- Anyone invited, registering free, no vendor record needed first
Comparing more than one bid
- ERP purchasing module alone
- One supplier, one price; a second bid goes in a separate spreadsheet
- VEXORS
- Every bid on the same request lines, compared side by side
Bidder questions
- ERP purchasing module alone
- Handled by phone or email, one bidder at a time
- VEXORS
- Asked inside the tender, answered once, published to every bidder
A late change to the request
- ERP purchasing module alone
- Resent by email; no way to confirm who saw it
- VEXORS
- Sent to every bidder at once; an outdated bid is flagged
Unpriced or missing items
- ERP purchasing module alone
- Not detected; the lowest total can hide the most left out
- VEXORS
- Priced back in at the estimate or the median before ranking
The reason behind the winner
- ERP purchasing module alone
- No field for it; rebuilt from memory when finance asks
- VEXORS
- A written reason beside every score, kept with the tender
Who approved the award
- ERP purchasing module alone
- Not recorded as a distinct step
- VEXORS
- Recorded by name against the award
The purchase order, invoice, and payment
- ERP purchasing module alone
- Raised, matched, and posted
- VEXORS
- Unchanged: still raised, matched, and posted in the ERP
Reorders belong in the ERP. Decisions belong on VEXORS.
Structured sourcing is not the right call for every purchase. Here is how to tell which one fits the purchase in front of you.
The module alone is enough when
- The purchase is a reorder from a supplier already under contract, at a price already agreed.
- It is a catalog item replenished on a fixed schedule, with no reason to check the market again.
You need VEXORS when
- More than one supplier should be bidding before anyone commits.
- The category has not been sourced before, or it has been long enough that prices or suppliers may have moved.
- The purchase needs a documented reason, because finance or an auditor will ask how it was decided.
Whether the supplier actually delivered. The module shows what a supplier was paid. It holds no record of whether they delivered on time or how they compared to others who bid, because neither side was ever asked to rate the other.
What actually changes, for IT
Nothing gets ripped out. The ERP stays the system of record for purchase orders, invoicing, and payment, exactly as it is today. VEXORS sits in front of it as the step where the supplier gets chosen, running the RFQ, RFP, or RFI and collecting the bids before anyone raises a PO. There is no data migration, because none of the ERP's data moves.
The security and compliance questions that come up next are answered on the VEXORS security page.
Who this changes things for
Procurement leads and buyers
Anyone running requests today by phone, email, or a shared inbox, on top of an ERP that only sees the result once a supplier is already chosen.
Finance and internal audit
Anyone who has had to explain after the fact why a supplier won, using an email thread or someone's memory instead of a record kept with the request.
IT and systems owners
Anyone asked to keep the ERP as the single system of record, with no new integration, no data migration, and nothing to rip out to add sourcing in front of it.
The handshake
The tender runs on VEXORS
Suppliers respond to the RFQ, RFP, or RFI with bids against the same line items, so the responses sit side by side instead of arriving in different formats.
The buyer decides
AI scoring ranks the bids and writes out the reason behind each score. The buyer reviews that ranking and chooses the supplier. VEXORS never awards on its own.
The award moves to the ERP
The awarded supplier and the agreed price go into the ERP the same way any purchase order does today, entered by whoever already raises POs on the team.
The ERP takes it from there
The purchase order, the invoice match, and the payment stay exactly where they have always been. VEXORS involvement ends at the award.
