Companies sell and buy business electronic equipment from each other, in lots or per unit, for reuse or recycling. The platform handles the process and the paperwork.
Each company has a single client account and registers as a seller or as a buyer. Selling and buying are capabilities the simby team validates separately, because the required documents differ. A company can have both: the second one is requested later, inside the platform.
Choose whether the company registers as a seller or as a buyer and enter the country, tax number, name, head office and contact. Whoever registers becomes the account owner and confirms the email address.
The simby team reviews the registration. Once the account is approved, the person who registered receives an email to set a password and sign in.
Inside the platform, the company uploads the documents for the chosen capability and the simby team checks them. Buying waste requires a valid waste management permit; its expiry date is recorded and monitored.
With the capability active, the company sees full lot details (photos, composition, collection site) and can bid, buy or publish.
For lots sold whole: a laptop fleet, a server room, the phones from an ended contract.
The seller describes the lot, uploads photos, and states its composition, waste category (LoW code) and collection site.
The simby team reviews the lot before the auction opens. The seller sets the deadline and, optionally, a reserve price below which no bids are accepted.
Buyers bid with a minimum increment over the best offer. Bids are anonymous between competitors. A bid in the last minutes extends the end, so nobody wins by a second.
At the deadline, the whole lot goes to the best offer. Winner, seller and other bidders are notified, and the contract and transfer certificate are issued automatically.
For uniform material that sells regularly: monitors, batteries, boards, cables, sold per unit, per kilo or per tonne.
The seller sets the unit price, the available quantity, the minimum order quantity and the allowed increments.
The buyer takes all or part at the listed price. For a different price, the buyer makes an offer on the item page, and the seller can accept, decline or counter.
An order, or an accepted offer, reserves the quantity for a period. If the reservation is not confirmed in time, the quantity returns to the market.
Buyer and seller arrange collection. The order follows the same paperwork as an auction.
Both sell equipment to validated companies. They differ in what is sold and how the price is reached.
| Auction | Direct sale | |
|---|---|---|
| What is sold | The whole lot, at once | Units or weight, in partial quantities |
| Price | Best offer by the deadline; optional reserve price | Unit price set by the seller |
| Negotiation | None: the highest bid wins | Yes, by offer and counter-offer on the item page |
| Minimum quantity | Not applicable | Set by the seller, with increments |
| Duration | End date, extended if there is a late bid | While quantity is available |
| Who sees what | Bids anonymous between competitors | Each offer is private to buyer and seller |
The transaction is recorded on the platform from start to finish, with the documents the law requires to transfer waste.
Issued automatically at closing, with the parties, lot composition and value. Available to both buyer and seller.
When the lot is waste, transport requires an electronic waste transport form (e-GAR). The platform tracks its status until delivery.
The treatment certificate and treated weight are recorded on the lot itself, for traceability and reporting.
Outbid, auction won, new offer, order received: by email, in the apps for iPhone, iPad and Mac, and in the notification bell.
Several people from the same company can use the platform, each with their own role.
The account owner invites colleagues and decides what each does. An operator prepares auctions and items, but only an owner launches them for sale, and owners are notified when a sale is waiting. A buyer bids and orders within the set limit.
Each user can have a limit. A bid, order or offer above it waits until the owner approves.
Every bid, offer and order is linked to the person who made it, and the owner is notified of everything the team does.
A marketplace where companies sell and buy business electronic equipment, working or end-of-life, for reuse or recycling. Whole lots are sold at auction; material sold per unit, per kilo or per tonne is sold by direct sale.
Currently in Portugal, with planned expansion to Spain and the rest of the European Union. The platform complies with national law and with Regulation (EC) No 1013/2006 on shipments of waste.
Business electrical and electronic equipment classified under the European List of Waste (LoW codes), industrial or household in origin, hazardous or non-hazardous. The category of each lot or item is given when it is published and confirmed by the simby team.
Any company can register, as a seller or as a buyer. Each capability has its own documents, which the simby team validates before activating it.
Buying waste requires a valid waste management permit. Its expiry date is recorded and the capability is suspended if the permit lapses.
Under "Sign in / Register", choose "Create account". State whether the company registers as a seller or as a buyer, the country, the company details and the contact, and confirm the email. No password is asked at that point: once the account is approved, you receive an email to set it and sign in.
Yes. A company has a single account and can have both capabilities active at the same time, with both areas in the same menu. A company registered as a seller requests the other under Help, "Register as buyer", and vice versa.
Yes. The account owner invites colleagues and decides what each can do: prepare sales (operator), buy (buyer) or manage the account (owner). The roles available depend on whether the company sells, buys or both, and only an owner launches sales. A purchase limit can also be set per person; above it, the bid, order or offer waits for the owner's approval.
At auction, the whole lot goes to the best offer by the deadline, with an optional base price. In direct sale, items are sold per unit, per kilo or per tonne at a unit price, and the buyer takes all or part, above the minimum quantity. The How it works page compares both in detail.
In direct sale, yes: the buyer makes an offer on the item page, and the seller can accept, decline or counter. An accepted offer immediately becomes an order at that price. At auction there is no negotiation: the highest bid wins.
No. Bids are anonymous between competitors: each buyer sees how many bids there are and their own position, not who is bidding. The seller only learns who won after the auction closes.
The auction end is extended by a few minutes so other buyers can respond. A lot is never decided by seconds.
A simby commission applies to every sale: 5% on auctions and 10% on direct sale, plus VAT at the legal rate in force. By default it is paid by the buyer; when it is agreed that the seller pays it, that company's lots state that no commission is added. Before you bid, make an offer or order, the platform always shows the calculation and asks you to confirm.
It depends on the terms in the listing (Incoterms). Under EXW, the most common, the buyer covers transport and collection. Other terms, such as DAP or FCA, shift part of that responsibility to the seller.
When an auction closes, the platform automatically issues the contract and the transfer certificate. When the lot is waste, transport requires an electronic waste transport form (e-GAR), whose status the platform tracks until delivery; the treatment certificate is attached to the lot.
The platform notifies you by email, in the apps for iPhone, iPad and Mac, and in the notification bell: outbid, auction won, new offer, order received, approval requests. Both the person who acted and the company owner are notified.
