About the project

Snabzhenets is a B2B procurement platform for construction companies. Buyers prepare a requisition, receive supplier offers, compare line items and select a supplier. Purchases connect to sites, counterparties, budgets and team tasks.

We developed the public website and the platform portal. The portal includes a catalogue, requisition approvals, CRM and financial documents. AI helps extract items from estimates and photographs and analyse offers; users review the results and decide what to save.

What it does

01

Requisitions, tenders and quotes

Purchase lists, order details, supplier offers and line-by-line comparison, with supplier selection and order history.

02

Catalogue and document import

Select catalogue items or extract lines from an estimate, specification or photograph of a table, then review them before adding them to a requisition.

03

Site budgets

Plan purchases by project and line item, compare requisitions with budgets and see deviations during approval.

04

Procurement CRM

Orders, counterparties, tasks and deals, with filters and links between related records.

05

Invoices and bank statements

Track supplier invoices and outstanding amounts. Match payments from a bank statement file in 1C format; the user confirms which payments to record.

06

AI in procurement

Supplier suggestions, quote analysis, reliability indicators, price forecasts and guidance. Recommendations support the buyer’s decision and review.
