Compare Supplier Offers, Negotiate, and Pick the Best
Once the offers are in, the hard part begins: they use different line orders, different descriptions, and different bundles, so comparing them fairly means rebuilding every quote into the same shape. Do it by hand and you either take hours or take the headline number at face value.
Streckenheld AI lines the offers up for you. It matches each supplier's lines back to your bill of quantities, builds a price matrix with the cheapest price flagged on every line, and writes a category-by-category comparison that names a recommended supplier — so your decision is about judgment, not spreadsheet wrangling.
Key features
- Price matrix — a suppliers × positions grid; each supplier's lines are matched to your BOQ by EAN, product number, and position, then by AI for the rest, so you compare like for like
- Cheapest per line — the lowest price on every position is flagged automatically, with a count of how many suppliers quoted it; positions a supplier skipped show as a gap
- AI comparison report — a markdown breakdown grouped by inferred category (concrete, insulation, steel, fasteners, tools, services) with a subtotal per supplier and a recommended supplier per category
- Overall recommendation — grand totals, a tally of categories won, and a one-line recommendation that also weighs coverage, payment terms, and delivery — not just price
- Comparison instructions — steer the AI per request ("prioritize delivery speed", "ignore offers without insulation", "prefer this supplier all else equal")
- Negotiation mode — override unit prices in the matrix to simulate a negotiation and see the impact before you pick up the phone; draft a reply to a supplier with AI
- Accept the winner — accepting an offer files it as a framework contract for the site and kicks off catalog and price-checking, so future invoices are validated against the agreed prices
- CSV export and inline previews — export any comparison table and preview every offer file without leaving the page
How it works
- Collect the offers. After you prepare and send the RFQ, suppliers submit prices or PDFs and the AI extracts each offer's line items.
- Build the price matrix. The AI matches every supplier line to your positions and lays them out side by side, flagging the cheapest price on each line.
- Add your comparison instructions. Give the AI any guidance specific to this decision — weighting, exclusions, preferred suppliers.
- Generate the AI comparison. The model streams its reasoning and produces the category-by-category report: recommended supplier per category, then an overall recommendation.
- Negotiate. Use negotiation mode to test price changes, and draft a reply to push for better terms — optionally checking each offer against your budget estimate.
- Award and lock it in. Accept the winning offer; it becomes a framework contract so agreed prices are enforced on every future invoice.
Who it's for
Offer comparison is for procurement managers and project leads who need to award work fairly and defend the decision — whether the offers arrived through the formal request or off-channel. The AI does the "line up the columns" work and surfaces the trade-offs, so you choose the best supplier on the merits and move straight into negotiation.
