Record the purchase or trade-in of used smartphones, tablets and PCs from private sellers, with the personal data required by used-goods trading regulations, an auto-generated purchase document, and a linked warehouse stock entry.
In a repair shop for smartphones and PCs, it is common to buy or take in trade a used device from a customer: an old phone traded in against a new one, a laptop the customer no longer wants repaired and prefers to sell, a batch of devices bought to strip for spare parts. Fixh IT's "Used device purchase" module is built exactly for this: it records the purchase from a private seller with all the personal data required by regulations on trading second-hand goods, automatically generates the purchase document in PDF (ACQUISTO_USATO_*.pdf), and at the same time creates a warehouse stock entry, so the device is immediately available to be resold as refurbished, offered as a trade-in, or stripped for spare parts.
Why it matters for a repair shop
A smartphone and PC repair shop constantly buys used devices, often from the very same customers who walk in for a repair. Someone with a cracked-screen phone may decide to sell it as-is instead of repairing it, or use it as a partial trade-in on a purchase or a repair job. Without a tracked purchase document, these transactions would fall outside both tax compliance and warehouse traceability. The module connects the private purchase directly to the shop's document flow — the same environment where you manage repair quotes, warranties, and electronic invoices.
How it works in practice
You register the seller (the private individual handing over the device) with their full personal details and an ID document, as required by the regulations on trading second-hand goods. You then describe the purchased device — a smartphone, a tablet, or a laptop — including brand, model and condition, and the agreed price.
Once all the data is entered, the system automatically generates the compliant purchase document, ready for filing or, if required, for submission to the relevant authorities. At the same time, the purchase automatically creates a linked warehouse stock entry ("Load from used device purchase"): the device enters stock with its own product record, ready to be resold as refurbished, used as a source of spare parts (screens, batteries, components), or kept aside for a future trade-in.
You can attach photos and files (jpg, png, pdf) to the document, which are automatically appended to the purchase PDF — useful for keeping the seller's ID photo or pictures of the device's condition at pickup. To speed this up at the counter, the system also generates a QR code with a temporary link (valid 15 minutes): the seller scans it with their own phone and uploads the photos directly, without using the shop's computer. The company's purchase contract template is also automatically appended as a final section, so the whole file — personal data, device description, attachments and contract — stays in a single PDF.
Quick guide
- Go to Documents > Used device purchase and create a new record.
- Enter the seller's personal details and ID document data.
- Describe the purchased device (smartphone, tablet or PC) with brand, model, condition and the agreed price.
- Generate the mobile upload QR code if you want the seller to photograph the ID and device from their own phone.
- Save the record: the system generates the ACQUISTO_USATO_*.pdf document and automatically creates the linked warehouse stock entry.
- Check the warehouse to confirm the purchased device was correctly added to stock.
- Decide the device's destination: resale as refurbished, spare-parts reserve, or a future trade-in.
Real use cases
A customer walks in with a cracked-screen iPhone asking for a repair quote: the technician determines the part cost is not worth it compared to the device value, and offers to buy the phone as a partial trade-in on another smartphone on display. With the used device purchase module the transaction is recorded, the document is generated, and the old iPhone enters stock as a spare-parts source for similar repairs.
A customer brings in a laptop they no longer use and prefers to sell rather than repair for a minor fault: the shop buys it, refurbishes it internally (cleaning, battery replacement, system reinstall) and resells it as refurbished, with a digital warranty generated at the time of sale.
A refurbished-device reseller regularly buys batches of used smartphones from private sellers to stock their sales counter: each purchase is recorded individually with the module, keeping traceability of every seller and generating a separate document for each device.
Tips and best practices
Always attach a photo of the seller's ID and a few pictures of the device's condition at pickup: in case of later checks or disputes, having everything documented in the same PDF avoids searching through emails or shared folders. Use the mobile upload QR code whenever the seller is at the counter: it is faster than photographing with the shop's camera and transferring the files manually. Always note the IMEI or serial number when available, so the stock entry stays traceable even in case of later resale or provenance disputes.
Common mistakes to avoid
The first mistake is not generating the purchase document right at pickup, postponing it to "later in the day": you risk forgetting important details or, worse, operating without traceability in the meantime. Another common mistake is confusing this module with a regular supplier stock load: a used device purchase always involves a private individual, not a supplier company, and requires the personal data and ID document set out by the specific regulations. Finally, avoid recording the purchased device without properly linking it to the warehouse stock entry: you would lose traceability between the purchase document and the physical stock.
