About the project

Neurosnab is a large B2B procurement platform for construction companies. Requisitions, supplier tenders, quote comparison, a product catalogue, budgeting and the finance loop all live in one window. Fewer phone calls and spreadsheets, more competition for every order and far more visibility in purchasing.

We ran both the public site neurosnab.tech and the working portal lk.neurosnab.tech — front end and back end. The part we are proudest of is the six AI agents wired straight into everyday work: they shortlist suppliers, normalise quotes to comparable units, score supplier reliability and read cost estimates from a photo.

What it does

01

Tenders and quote comparison

One comparison matrix for every quote: collapsible categories, pinned and sortable columns, and separate Compare and Award modes.

02

A 738,000-item catalogue

Fast catalogue search and automatic line-item matching straight into the order, drawn from a very large product database.

03

Budgeting

Planned versus actual prices, weighted average cost across winning quotes and shortfall control on every line.

04

Procurement CRM

Orders, counterparties, tasks and deals, with cross-links between cards and compact filters.

05

Finance and 1C

Invoices and commissions integrated with 1C accounting; wallet, rewards and payment statuses.

06

Six AI agents

Assistant, supplier shortlisting, quote comparison, reliability scoring, price forecasting and photo recognition of cost estimates (vision).
