EDITIONS

Pick the one with your articles in it.

One product, three trades, three languages. Each edition is finished, walked end to end and running on a public address — you see your own trade on the screen before the first meeting, not a slide about it.

NERVE TyreLIVE

Car, truck, agri, OTR. Dimension, load and speed index, DOT, energy label — and PNEUSCOPE, the public-tender radar matched against your stock.

HOW IT IS BOUGHT

The way Europe buys a portal — minus the unknowns.

Three fixed prices, one maintenance line your accountant already has a name for, and nothing else. The market's habit is €25,000–35,000, five to six months, and a specification written after you sign. This is the other way round — and it starts at €1,500.

STARTER€1,500fixed

Catalogue built from your price file, customers, users and per-customer contract prices, ordering from a spreadsheet — the buyer pastes their own list, NERVE parses it, matches it and prices it. Works without an ERP: a price list in a spreadsheet is enough. Live in 14 days.

STANDARD€3,500fixed, integration included

Everything in Starter, plus live stock and prices read from your ERP (a documented web service, included in the price), sealed quotes with validity, credit limits, multiple warehouses. The number is final before work starts, never after.

PREMIUM€6,000fixed

Everything in Standard, plus the substitution logic (technically equivalent · approved alternative · near, not equal), several editions and languages, white-label for ERP partners, and ERPs without a documented service — we bring your ERP vendor to the table.

MAINTENANCE & HOSTING€149 / month

From the month the portal shows your own prices. Single-tenant hosting, backups, every update as it is released, one working day response. The licence is in here — no separate line. Extras: none. Not per user, not per order, not a share of turnover, no "phase two" priced after you sign.

THE FOURTEEN DAYS

  1. Day 1Your price file arrives in the pilot format — we send the template.
  2. Day 3The catalogue is built from it. You see your own articles, your own prices.
  3. Day 7Customers, price tiers, terms, documents, users.
  4. Day 14Go-live, walked on your data. Maintenance starts the month your customers see their prices.

The ERP binding has its own clock: it starts the day your ERP vendor hands over a test endpoint. Until then you are live on the file, and nothing waits for the vendor.

THE EMPTY SHELF

The portal that sells when the shelf is empty.

Your portal says “not available” twenty times a day. Every one is a phone call you don't get and a sale your competitor makes. NERVE answers the way your best seller would — with the alternative, and the reason it is the alternative.

TierOffered to the buyerHow it was reachedOrigin
1The article requestedThe catalogue record.catalogue
2Technically equivalentComputed from recorded attributes. Only what a source actually published is compared.computed
3Approved alternativeStated by the seller, shown with the fact that a person approved it.stated
4Near, not equalComputed, labelled near rather than equal, and the differing attribute is named.computed

A substitute a person approved is never dressed up as something the software worked out, and something the software worked out is never dressed up as approved. The buyer is told which he is looking at, every time.

There is no similarity score. A number lets a buyer read 0.87 as “close enough” without ever seeing which attribute differs — so the difference is named instead of scored.

TABLE STAKES

Everything a trade portal must have, before anything else.

None of this is a differentiator. It is the price of being taken seriously by a distributor, and it is all here. The screens are built from the product's own design tokens, not photographed.

01 / 04

Per-partner contract price

Two partners open the same article and see their own negotiated net. Nobody sees anybody else's, and nobody in the back office is asked to confirm it by phone.

And where it came from. Every net carries the price list it was read from, the tier that applied, and how old the reading is. A price with no provenance is a price your partner will ring up to check — which is the call the portal was bought to prevent.

Live stock, per warehouse and per source

Availability across your own warehouses and your supplier feeds, current, with the delivery estimate that follows from it.

And how sure it is. Each figure states whether it is exact, at-least, or unknown, which kind of source produced it, and when it was last read. A stale number presented as fresh is worse than no number: it gets promised to a customer.

A whole order, pasted

Forty lines out of a spreadsheet, an email, or a WhatsApp message from the workshop. Every line comes back parsed, matched and priced — in your customer's own codes.

Line by line, not all or nothing. A malformed line is corrected on its own row with the correction offered; the other thirty-nine go through. Batch refusal is how a portal loses to a phone call.

Sealed quotes, credit as a decision

A quote is a sealed version; the buyer's acceptance binds to exactly the version he saw. Nobody ever again argues about which offer was the real one.

The limit is a decision, not a wall. Over the credit limit, the order becomes a request routed to a person with the numbers in front of them — because the answer to a good customer at 103% of his limit is usually yes.

TYRE EDITION · PNEUSCOPE

They know a tender exists. We know if you can win it.

Public tenders matched against your catalogue and your stock — not a keyword alert. Each carries a commercial position: covered from the yard today, a sourcing decision, partial, or “review required” because the notice says something NERVE will not guess at.

Keep your tender service. It tells you a tender exists. NERVE tells you whether your stock covers it, which article, and where the gap is — nobody else has your stock in the comparison.

Don't take our word for it. Walk in.

Every edition is on the internet, running, and the access word is printed here. No form, no call, no slide deck — open it and decide for yourself in ten minutes.

Every screen is the real product on synthetic data. A brochure can promise anything. A working portal has to keep it.

HOW IT IS BUILT

Rules that fail the build, not rules in a document.

Anyone can write a standard down. These are the ones a commit cannot get past.

A pure domain

The commercial logic is a package with no I/O — no database client, no HTTP, no framework. A pricing or substitution decision cannot quietly come to depend on a request.

Provenance travels with the number

A stock figure carries the kind of source it came from, whether it is exact or at-least, and how old the reading is. A surface that cannot state where a figure came from does not print the figure.

Your own database

Every customer gets a separate database. Your prices and your buying terms are never in a table next to a competitor's.

Three languages, structurally

EN, HR and DE are a message layer the components read, not strings living inside them. A new screen cannot be born monolingual.

Fail closed

Conflicting sources do not resolve to the newest one. Missing authority does not resolve to a default. Both resolve to a refusal the buyer can read and act on.

Your ERP stays in your building

NERVE reads what your ERP publishes and records what your customers ask for. The system of record stays the system of record.

LIMITS

What we deliberately do not do.

Every vendor's site lists what they have. This is the other list, because you will find it out in week three anyway and it is cheaper for both of us if you find it out now.

Card payments

A trade counter buys on invoice against a credit limit. We route the limit as a decision a person makes, and we do not pretend a card terminal is the same thing.

Promotions, vouchers, baskets

Consumer commerce mechanics. Well served by ordinary shop software, and not what a distributor's desk needs.

Vehicle lookup by make and model

A large database serving a consumer choosing two winter tyres. Real work, genuinely useful, and not our buyer.

Replacing your ERP

Your system of record stays the system of record. Anyone offering to replace both at once is selling you a two-year project.

WHO

You will talk to the person who wrote the code.

There is no account manager here, no discovery workshop, and nobody who will take your question away and come back on Thursday. The person who answers your email is the person who built the product this page describes.

That is a limit on how much we can take on at once, and it is the reason the answers are specific — and the reason the first three distributors get their requests built first.

PLAIN TALK

Before you write to us.

The demonstration data is invented.Articles, prices, stock, dates and manufacturers. The arithmetic is real; the catalogue is not.
The price on this page is the price.The ERP integration is inside Standard for any ERP with a documented web service; if yours has none, it is Premium — decided after one look at your interface, before you sign. There is no second number after signature.
We replace the portal, not the ERP.And we will not bolt this onto an existing portal. If yours is working for you, this is not for you.
