You want to start selling refurbished phones on Back Market. Then you discover that refurbished smartphones need to be tested and certified for marketplace sales. Back Market requires sellers to follow its Quality Charter and carry out detailed quality inspections before devices are sold.
So the next step is finding the right software.
Several established providers offer diagnostics and certification for the secondary device market. The certificate itself, however, is only one part of the job. A refurbisher also needs to test devices, check their status, grade their condition and keep track of inventory.
So what should you look for when choosing software for your Back Market business?
Key Takeaways
- Back Market requires refurbished devices to meet its quality and inspection requirements.
- Certification should be based on detailed device testing, not treated as a separate document.
- NSYS combines diagnostics, certification, AI-powered grading and inventory management.
- NSYS Diagnostics supports 60+ tests and detects more than 100 functional defects.
- NSYS stock certification is validated for resale on Back Market.
Start with the Certification — Then Look at What Comes Before It
Certification is a requirement, so it makes sense to start your search with software that supports Back Market sales.
But two solutions that both provide certification can still offer very different workflows.
Before choosing, look at how the software handles the actual device. Can it perform the checks you need? Does it identify issues that affect resale? Can it help with grading? Can you keep the device's test results and inventory information together?
These questions matter because the certificate is based on everything that happens before it is generated.
Diagnostics That Support Certification
NSYS Diagnostics runs 60+ tests across supported iOS and Android devices and can detect more than 100 functional defects. The checks cover key device functions and include parameters such as battery condition, IMEI blacklist status, SIM lock and other hardware issues.
For a refurbisher, this means technicians have a structured testing process for every device instead of relying on manual checks and separate records.
The results can then be used as the basis for certification and further processing.
Certification for Back Market Sales
NSYS Certification links the report to the individual device and its diagnostic results. NSYS stock certification is validated for resale on Back Market.
That gives sellers the documentation needed for marketplace sales while keeping the certification connected to the testing data behind it.
When comparing providers, this is worth checking carefully. A Back Market certification report should not be viewed in isolation from the testing process that produced it.
Grading Is Part of the Same Decision
Passing functional tests does not tell you what a refurbished phone should be worth.
Cosmetic condition also affects its grade and resale price. NSYS Autograding uses AI to assess cosmetic defects and assign a grade based on the device's condition.
Having diagnostics and grading within the same NSYS ecosystem means the functional and cosmetic condition of a device can be considered together when preparing it for sale.
Back Market itself uses cosmetic grades alongside its functional quality requirements, making grading an important part of the resale process.
Keep Your Inventory Connected
Once you start processing more devices, another problem appears: keeping track of them.
Which IMEI is in stock? Has the device been tested? What grade did it receive? Has it been certified? Which warehouse is holding it?
NSYS Inventory provides IMEI-based inventory management and supports stock tracking across multiple warehouses. This allows device information to stay connected as a phone moves through the refurbishment process.
For a Back Market seller, the workflow can cover:
Inventory → Diagnostics → Grading → Certification → Sale → Fulfilment
NSYS Inventory can also support the wider operational side of the business, including managing stock and device records as sales volumes increase.
Why Choose NSYS?
The strongest reason to choose NSYS is not simply that it can provide certification for Back Market. Other professional solutions can also support marketplace certification and device testing.
The difference is how much of the refurbishment process you can manage within one ecosystem.
With NSYS, you can combine:
- Diagnostics — 60+ tests and detection of 100+ functional defects
- Certification — certification validated for Back Market resale
- Autograding — AI-powered cosmetic grading
- Inventory — IMEI-based stock management and multi-warehouse tracking
- Data Erasure — secure device wiping before resale
This is useful when you are building your Back Market operation from scratch. You can start with diagnostics and certification, then add grading, inventory management and other tools as your volumes grow.
You also avoid building your workflow around separate systems for every stage of device processing.
How to Choose Your Back Market Software
Before making a decision, check five things:
Certification: Does the provider support the certification required for Back Market?
Diagnostics: How many tests does it perform, and which defects can it detect?
Grading: Can functional testing and cosmetic grading work together?
Inventory: Can you track each device by IMEI and keep its history connected?
Scalability: Will the same setup work when you move from dozens of devices to hundreds or thousands?
NSYS covers all five areas, giving refurbishers a single ecosystem for testing, certification, grading and inventory management.
