Can bids carry the documentation we require?

Yes. State the required documents in the request and suppliers attach them to their bids, so compliance paperwork arrives with the price, not after the order.

How do I know a new supplier is credible?

Each supplier carries a trust score built from completed deals, bids, awards, and buyer ratings on the network, alongside the qualification forms you send before they bid.

Does VEXORS manage safety data sheets or quality control?

No. VEXORS runs sourcing through award. You can request and attach documents during bidding; ongoing SDS management and QC stay in your existing systems.

What does it cost to run chemical RFQs on VEXORS?

You can start on the free plan and publish real requests with it. Paid plans add capacity and advanced tools as your volume grows. Suppliers never pay to bid, so asking your current suppliers to participate costs them nothing.

Can suppliers we do not know find our request?

Only if you want them to. Invite just your approved suppliers, or open the request so verified suppliers in matching categories can find and bid on it. Opening it is how buyers build a second source without cold-calling for one.

Does VEXORS work in Arabic?

Yes. The whole platform runs in English and Arabic with a full right-to-left interface, and a request published by an English-speaking buyer can be answered by an Arabic-speaking supplier without anything getting lost between them.

Can bidders attach a certificate of analysis and safety data sheet to their bid?

Yes. Name the documents you require in the request, whether a certificate of analysis, a safety data sheet, or a certificate of origin, and the bidder attaches them with the price, so the paperwork arrives with the bid instead of being chased after the order.

What happens if a supplier leaves a line item unpriced?

VEXORS counts the unpriced line and prices it back in at your estimate or the median of the other bids before ranking, so a bid that looks lowest because it skipped a line does not win by default. A declared lump sum still counts as priced.

Can we require packaging and Incoterms as part of the request?

Yes. Add the packaging format and the Incoterm you require as custom fields on the request line, or as required questions in the questionnaire, so every bidder states them against your specification instead of burying them in a covering email or a separate commercial note.

Do suppliers pay to bid on our chemical RFQs?

No. Bidding stays free on every plan, whether the supplier is one you already work with or one who found your open request in a matching category and registered to respond. You pay for the platform; a supplier never pays a fee to bid or to win.

Can more than one person on our team approve the award?

Yes. Several people on your team can work on one request, price lines, and answer questions, and every approval is recorded by name against the request, alongside the AI scores, the reasons behind them, and any revisions, so the award decision has a named record behind it.

Does VEXORS replace our ERP for purchase orders and payment?

No. VEXORS runs the sourcing itself, from the structured request through bids, evaluation, and the award, and works alongside the ERP you already use, so purchase orders, goods receipt, and payment stay exactly where they are today.

What is spec-driven sourcing for chemicals?

In chemical buying the specification is the purchase: grade, purity, packaging, shelf life, and the documents that must travel with the product. Spec-driven sourcing publishes those requirements once as a structured request, so every bid answers the same spec and states its compliance, instead of a stack of PDFs that each define the product differently. VEXORS covers sourcing through award; quality control, safety-data management, and logistics stay in your existing tools.

The spec is the request

Publish grade, purity, packaging, quantity, and required documentation as structured line items, so bids come back against your definition of the product, not each supplier's.

Compliance visible before the price

Bids state spec compliance and carry the requested documents, and the AI score weighs compliance and terms alongside price, with a written rationale you can defend.

A vetted bench of suppliers

Discover suppliers by category, qualify them with onboarding forms, and read trust scores built from completed transactions before a kilogram ships.

Common chemicals use cases

Sourcing raw materials and intermediates against a tight specification with comparable bids.

Second-sourcing critical inputs so a single supplier's outage cannot stop production.

Qualifying new suppliers with structured forms and documentation before a first order.

Keeping a documented record of what was specified, offered, and awarded for every purchase.

Chemical sourcing on VEXORS, in practice

The spec problem

Where chemical buying actually goes wrong

The failure mode in chemical purchasing is rarely the price; it is the quote that priced a different product. One supplier assumes technical grade, another quotes food grade, a third substitutes packaging, and the differences surface after the order is placed. Documentation follows the same pattern: the SDS and certificates get chased by email after the PO instead of arriving with the offer. Add a single qualified source for a critical input, and the buyer is carrying spec risk, compliance risk, and supply risk on a workflow made of attachments and memory.

A quote assumes technical grade when the request asked for USP or food grade
Packaging is substituted, bags for drums or totes for IBCs, without being flagged
The certificate of analysis and the safety data sheet are chased by email after the purchase order
A single qualified source for a critical input carries spec, compliance, and supply risk at once

Structured requests and documents

What a structured chemical request looks like

On VEXORS the request itself carries the definition of the product: each line states the grade, purity, packaging format, and quantity, and the questionnaire names the documents that must come with the bid. Suppliers answer that structure, so offers arrive against the same spec with compliance stated and paperwork attached. Clarifications run inside the request, and when bids close, the AI evaluates each one against your weighted criteria, compliance and terms alongside price, and recommends with written reasoning you can defend to anyone.

Each line states grade, purity, packaging format, and quantity, not a free-text description
The questionnaire names the documents that must arrive with the bid, such as a certificate of analysis or a safety data sheet
A bidder's question is answered once inside the request and published to every other bidder
An amendment to the specification reaches every bidder at once, and a bid priced on the old version is flagged

Levelling and rate checks

Gaps priced back in before a rate slips through

A quote that leaves a line unpriced looks cheaper than it is until the gap gets counted. VEXORS prices every unpriced line back in at your estimate or the median of the other bids before ranking a single total, so the lowest number as submitted stops winning by default. A bidder who declares a section as a lump sum still counts as priced, only a silent gap gets added back. Every rate with three or more prices behind it is checked against the median for that line. A rate far out of line (a pigment quoted at a fraction of the others, say) is flagged with its ratio before you decide, not after a drum arrives in a grade you did not order.

The record, second cycle onward

Month two: the record starts paying for itself

The second cycle is where structure compounds. Repeat purchases reuse the first request as a template, so publishing takes minutes. The suppliers who bid well are now rated and carry visible history, which makes second-sourcing a critical input a decision instead of a project. And every purchase leaves a complete record of what was specified, what each supplier offered, and why the award went where it did, which is exactly what an auditor, a customer, or your own quality team eventually asks for.

Who runs chemical sourcing on VEXORS

Producers and compounders

Buying resins, monomers, catalysts, and process chemicals against a specification, and comparing suppliers on delivered grade and total cost, not the lowest line on a PDF.

Formulators and blenders

Sourcing additives and actives by grade and purity for a formulation, where a certificate of analysis and a safety data sheet decide whether a cheaper quote is actually usable.

EHS, QA, and regulatory teams

Needing the certificates, safety data, and a documented record of what was specified, offered, and awarded, ready for an audit or a customer questionnaire.

Multi-site groups and distributors

Running the same specification across plants, or reselling to formulators, and needing consistent grade, packaging, and terms from more than one supplier at once.

How it works

From spec to award in four steps

Publish the spec

Grade, purity, packaging, quantities, documentation, and deadline in one structured request.

Invite and discover suppliers

Bring your approved suppliers and discover new ones by category. Bidding is free for them.

Evaluate every bid

Fifty bids evaluated, compared and scored in seconds, on spec compliance, documentation, and terms, not just price. The reasoning comes with it.

Award and rate

Award with the record behind you, then rate the supplier to strengthen the network both ways.

Structured RFQs, RFPs and RFIs, AI evaluation with levelling and rate checks, clarifications and the record run on every plan, including the free Explore plan, with the AI credits each plan includes. Questionnaires, saved templates, approval workflows and the construction BoQ workflow are part of the Scale plan.

Your first request can go out the day you sign up.
