There are many compelling reasons for suppliers and manufacturers of building materials to join the Q-platform. 1. Your customers will increasingly require it Your customers will continue to purchase your products in the usual way — specifying quantity, article number, and price in a standard purchase order. However, the logistics will be handled through our platform. To access delivery details for your customers, you simply maintain an account on the Q-Platform. We will schedule and list all pickups in advance, allowing you to confirm when orders are ready. From that moment on, we manage the entire logistics process. There is no longer any need for you to arrange transport. You will receive delivery confirmations and, where applicable, reports of any damages. 2. Let us handle all your logistics You can also use our system for all your other transport needs. Instead of managing logistics internally, we take care of it completely. This results in consistently lower transport costs and eliminates the need for in-house planning capacity. Over time, this can significantly reduce operational overhead. You can even use our storage capacity, allowing you to scale down or repurpose your own warehouse space. Read more here.(/supplier) 3. Sell directly to end users Our platform also enables you to sell directly to end users. You can supply products not only to our clients but to a broader market through the network. This opens up new sales channels, significantly increases your margins, and removes the handling and logistics costs normally associated with direct distribution.

◎ for Suppliers and Manufacturers of building materials Mar 4th 2026 No — we do not order materials. You will continue to receive orders directly from your clients, exactly as you do today. You can fully honour your existing commercial agreements. If your agreed selling price includes transport, you simply adjust your pricing accordingly. From a legal and contractual perspective: you enter into the purchase agreement directly with your client — not with us. Your client has a separate agreement with us covering the logistics services only. If and when you or your client use Qonstruct as the ordering platform, we will forward the purchase order to you on behalf of the client. However, we are not the legal purchasing party. We merely transmit the purchase order as part of facilitating the logistics process. We can also connect with your ERP system to automate this process.

◎ for Suppliers and Manufacturers of building materials V1.0 Our clients share the materials lists for the projects they are executing. This does not mean that purchase orders have already been placed with you. These lists reflect the overall materials planning for complete projects — sometimes scheduled years in advance. In many cases, the materials are not yet assigned to a specific supplier. Supplier selection can still take place during the construction process. Once the logistics process begins, however, the following information is shared with us: • Supplier name • Article description • Quantities (sometimes combined across multiple projects) • Delivery planning (provided separately) We do not have access to purchase prices or any commercial agreements between you and your client. If the client places an order through Qonstruct, we will forward the purchase order to you, including price information. You are free to make separate payment arrangements directly with the ordering client if desired. We do not require pricing details, provided they do not include logistics costs. We also do not charge any sales fees or percentage commissions on orders placed through Qonstruct. The advertised selling price is the full amount you receive. Transport is invoiced separately by us directly to the client.

◎ for Suppliers and Manufacturers of building materials Mar 4th 2026 We primarily share pickup information with you so you can prepare deliveries. This information is linked to the purchase orders that you should have received by that time. In addition, we provide monthly delivery updates covering all projects from all clients. This enables you to: • Gain visibility into future sales, revenues, and product volumes well in advance • Adjust your production or procurement planning in line with expected deliveries • Reduce warehousing and inventory costs These monthly reports provide a high-level overview and become increasingly detailed as delivery dates approach. At all times, you maintain full visibility of the entire logistics process.

◎ for Suppliers and Manufacturers of building materials Mar 4th 2026 We handle also the damages when delivered or picked up. You can see this on you dashboard on the Q-Platform.

◎ for Suppliers and Manufacturers of building materials Mar 4th 2026 Yes — we strongly encourage this. You can use the Q-Platform to enter purchase information from your other clients (or connect your ERP system), and we will plan the logistics within the same streamlined process. From there, you can choose to cover transport costs yourself or, as we typically do, have the client pay for transport.

◎ for Suppliers and Manufacturers of building materials Mar 4th 2026 When new clients place orders with you, you can request a credit check, which we can handle on your behalf. Of course, you are free to set your own commercial terms, such as advance payments or shorter payment periods. We do not get involved in pricing or payment arrangements.

◉ for Construction- and installation companies and their subcontractors Mar 4th 2026 We will never be the ordering party. You will be responsible for ordering (timely) and purchase pricing. We are responsible for the related logistics according your planning.

First, register (https://www.qonnected.io/auth/login)on the Q-Platform. On the Q-Platform, you will find our delivery requests for your products, planned by us on behalf of our clients. Each request includes a reference to the original purchase order sent to you by our client, allowing you to easily cross-check everything within your ERP system. Once the order is ready for pickup, simply mark it as “Ready,” and Qonnected will arrange collection and delivery. That’s it. You have full visibility of your logistics planning at all times — grouped per client or as a complete overview of all clients, by day, week, or month. We can also manage your entire logistics operation. This results in cost savings across the board: reduced warehousing, lower transport costs, and decreased personnel expenses. Transport is invoiced separately to your clients. Because we consolidate shipments, transport costs are always optimized — delivering significant savings for you and your customers.
