Buy, sell and deliver building materials –on one platform.
Construction firms, building material merchants and carriers work on the same orders, deliveries and invoices, and AI handles the routine in between.
From bill of quantities to final invoice — one platform.
Calculation, tendering, ordering, delivery, reconciliation — today it lives in spreadsheets, email threads and paper. Streckenheld runs the whole chain in one place, with AI doing the reading, matching and chasing.
Calculation & Quoting
Bid with numbers you can defend.
Bill of quantities
Upload the BoQ and our AI agent prices it line by line against your past quotes and framework contracts. A budget you can stand behind — in hours, not weeks.
Before you price, the AI checks every BoQ position against the measurement and specification rules and the contract terms against NEC, JCT or AIA conditions, with likely claims, risks to price in and questions for the client.
Only a functional road or bridge tender? The AI writes each piece of work as a standard position, from the Method of Measurement for Highway Works in the UK or your state DOT standard specifications in the US, citing its source in the specification.
Tender & Award
Every supplier quote, finally comparable.
Make or buy & procurement packages →
AI suggests self-perform, subcontract or evaluate for every BoQ position from your company's rules, and proposes the procurement packages, learnt from how you packaged earlier projects. You review and apply, then invite the suppliers.
Requests for quote
Send RfQs to all your suppliers in one click and collect their answers in a structured process — portal, PDF or scan. Negotiate in one place instead of twenty email threads.
Contracts & awards
Compare normalised positions side by side, award on real total cost, and turn the accepted quote into a contract your team can order against.
Ordering & Delivery
Order at the prices you negotiated. Every time.
Orders
Orders go out automatically from existing contracts and accepted quotes — at agreed prices — and clear your approval limits before they ever reach a supplier.
Site calendar
Every order, confirmation and delivery on one calendar per site. Your site managers see what arrives tomorrow, not what was ordered last week.
Deliveries
Track every order through to the site gate. No more "where's my truck?" calls to suppliers.
Invoice & Payment
Nothing gets paid that wasn't ordered, delivered and agreed.
Document reconciliation
AI reads every document — including handwritten delivery notes — links it to the right order, and flags every difference between order, confirmation, delivery note and invoice before you pay.
Approval workflows
Release rules that match how your team actually works — by site, role or amount, with a full audit trail.
Load carriers
Pallets, frames and returnable containers tracked per supplier, so deposits come back instead of quietly disappearing.
What makes it run
Underneath every stage: your systems connected, every document read, every euro visible.

Frequently Asked Questions
Learn more about Streckenheld's AI-powered platform.
AI agents are autonomous programs that handle one specific job end to end: reading a supplier quote, matching an invoice to its delivery note, chasing a missing order confirmation. They work inside your existing process and hand anything unusual back to your team — you decide, they execute.
Four ways, and you can use all of them at once. Straight from your ERP; through a dedicated email inbox your suppliers already write to; via WhatsApp, for anyone who'd rather photograph a document than scan it; and through our own app on site, where your team captures and signs delivery notes on the spot. Whatever the format — PDF, scan, photo or handwriting — the AI reads it and files it against the right order.
Streckenheld connects to your existing ERP through standard interfaces — BRZ, Nevaris, RIB, PDS and others. Nothing gets replaced: our agents read from and write to the system you already use, so orders, invoices and master data stay in sync without double entry.
Your data is hosted in the EU and processed under GDPR, with a data processing agreement in place. It stays yours: we don't train models on your contracts, quotes or invoices, and you can export or delete it at any time.
Streckenheld is model-agnostic. We run the model that fits the task, and if your IT has a preference or a policy — a specific provider, or an open model — we configure it for your instance. Either way your documents stay in the EU and none of them feed foundation model training.
Our AI compares every delivery note against the original order and the supplier invoice, handwritten ones included. It flags differences in quantity, price or item before payment — so discrepancies get resolved while you still have leverage, not after you've paid.
