Questions about the building materials marketplace

  • What is Extraflow Network?

    Extraflow Network is a free B2B marketplace for building materials. Manufacturers, distributors and builders' merchants sell to new contractors, and construction companies get verified quotes from suppliers. AI agents handle the requests, quotes and checks, and you approve every step.

  • Which building materials can I buy and sell?

    Everything a site needs: cement, aggregates and mortars, bricks and concrete blocks, rebar and structural steel, insulation, waterproofing, plasterboard, tiles, sanitaryware, plumbing and electrical supplies, paints and tools.

  • What is an agentic marketplace?

    In an agentic marketplace, AI agents do the work people used to do by hand: understanding what a site needs, finding suppliers who can deliver it, asking for quotes, comparing prices, lead times and delivery to site, and checking specs, CE marking, tax numbers and terms. You get a result ready to approve, not a list of links.

  • How do I get quotes for building materials?

    Type what you need, or upload a purchase order or bill of quantities. Extraflow searches verified building materials suppliers on the network and across the web, sends the requests and returns the best checked quotes side by side, with delivery to your site.

  • How do I find new customers for my building materials?

    Contractors, installers and construction companies in Portugal and Spain ask for materials every day. When a request matches your catalog, we bring it to you with the quote already drafted from your own prices and stock. You approve and send it in one click.

  • Does it work with my ERP?

    Yes. Extraflow connects to any ERP, including Cegid PHC, Cegid Primavera, SAP, Sage, Microsoft Dynamics and Odoo. No ERP? Upload your product list in Excel and we handle the rest.

  • How much does it cost?

    Joining is free and needs no credit card. All you need is your company details and a work email.

  • Who sees my prices and data?

    You choose whether your prices are public or only shown in your quotes. No quote is sent and no order reaches your ERP until you approve it. Our ISO 27001 certification is in progress.

Every request you don’t see is a sale a competitor makes.

And every quote you don’t compare is margin lost on the job. Joining is free and takes a minute.
