Generate PDF warranty certificates for smartphone and PC repairs or checkout sales, with a QR code and a public verification page the customer can check at any time, with no manual data entry.
When a customer picks up a freshly repaired smartphone or buys a device in-store, the warranty you offer matters as much as the job itself: it is what reassures them if the issue comes back in the following weeks. Fixh IT automatically generates the PDF warranty certificate from the data of the completed repair or the item sold at checkout, with a QR code linking to a public verification page: the customer can check the coverage's validity at any time, without calling the shop or digging through a drawer for the paper receipt.
Why it matters for a repair shop
In a smartphone and PC repair workshop, the warranty on the job is often the deciding factor that gets a customer to choose you over the shop next door: knowing that if the screen you just replaced comes loose after ten days the shop will fix it at no extra cost is a promise that needs to be formalized, not left to a verbal agreement. Likewise, anyone selling refurbished devices or accessories wants to be able to prove to the customer, months later, that the product was under warranty at the time of purchase. A publicly verifiable digital certificate removes any ambiguity on these points.
How it works in practice
A warranty can originate in two ways: when delivering a completed repair, or on a sale already recorded at checkout — in this case you can search for the reference receipt (by number, customer, or item sold) and automatically retrieve the product, price, and linked customer, without re-entering anything. You set the coverage duration (12 months by default, but customizable) and the system generates a sequential warranty number and a unique public code.
The generated PDF prominently shows "Certified warranty" and the coverage's expiry date, plus a QR code and a barcode linking to a public verification page reachable at /w/ followed by the warranty's unique code: whoever holds the document — even a customer who lost the original receipt, or a second owner after a resale — can check its authenticity and current status (active, expired) by simply scanning the QR code with their phone. The company's configured warranty terms are also appended as a final section, so all the conditions are in the same PDF.
Every certificate stays linked to the source repair or sale and to the customer's profile: from their own customer portal, the customer can find all active warranties without searching through old emails, and shop staff can quickly trace the coverage details when a warranty claim comes in.
Quick guide
- Go to Documents > Warranty and create a new certificate.
- Search for the reference receipt if the warranty relates to a sale already recorded at checkout, or link it directly to the repair just completed.
- Check or edit the coverage duration (12 months by default).
- Generate the certificate: the system assigns a sequential number and a unique public code.
- Hand the PDF to the customer, printed or by email, or make it available in their customer portal.
- In case of a warranty claim, check the status from the certificate record or from the public page with the code.
Real use cases
A customer picks up a smartphone after a screen replacement: at handover, the warranty certificate for the job is generated, with the QR code printed on the receipt. Three weeks later the touchscreen starts misbehaving: the customer scans the QR code, checks the warranty is still active, and comes back to the shop without having to dig up the receipt.
A shop sells a refurbished iPhone: at checkout, the just-issued receipt is searched, the sold product is linked, and a 12-month warranty certificate is generated, which the customer receives by email together with the purchase receipt.
A customer who bought a refurbished laptop six months earlier resells it to a friend: the warranty certificate with its public link is passed on to the new owner, who can independently check how many months of coverage remain, without contacting the original shop.
Tips and best practices
Always generate the certificate at the time of delivery or sale, not later: postponing it increases the risk of forgetting, especially on busy days. Print the QR code on a label to attach to the packaging or the device itself, in addition to the paper receipt: it makes verification even more immediate for the customer. Customize the coverage duration based on the type of job: a screen repair may warrant a different warranty than a battery replacement or a full refurbishment.
Common mistakes to avoid
The first mistake is generating the certificate days after delivery, perhaps "whenever there's time": the start date must match the actual delivery, otherwise the effective coverage ends up skewed. Another common mistake is forgetting to link the certificate to the source receipt or repair: without this link you lose the ability to quickly trace the transaction details in case of a dispute. Finally, don't rely on memory alone to remember which warranties are still active: always use the public code verification or the certificate record, which automatically computes the current status.
Frequently asked questions
Do I have to fill in the warranty certificate data manually? No, if the warranty relates to a sale you can search for the reference receipt and the data is retrieved automatically; if it relates to a repair, it links directly to the completed job.
Can the customer check the certificate without asking you in person? Yes, they can view it online via the QR code printed on the document, which links to a public verification page, or from their own customer portal.
Is the warranty linked to both repairs and sales? Yes, the certificate is generated both for completed repairs and for sales made at checkout, with the receipt searchable by number, customer, or item.
How do I know if a warranty is still valid? The status (active or expired) is automatically computed based on the start date and the set duration, and is visible both on the certificate record and on the public verification page.
Can I customize the warranty duration? Yes, the system suggests 12 months as a default, but you can change it based on the type of job or product.
What happens if the device is resold by the first customer? The certificate remains valid via the public code: whoever holds the document can check its authenticity and remaining coverage, even a second owner.
