Corporate phone buyback
Viper Second Life
You send the fleet list, you get a written offer within 24 hours. Per-device data erasure, certificates for your ESG report and payment within 15 days.
Almost every company that issues work phones also has a drawer nobody keeps track of. Inside are the devices from the previous procurement round: written off, switched off, still tied to a former employee’s account that nobody signed out. They bother no one, so the decision about them keeps being postponed — quarter after quarter, until there are enough of them that the decision becomes a project.
Viper Second Life is a buyback programme built for exactly that moment. You send the list, we send a written offer, we collect the devices against a handover record, erase the data and pay into the company account. At the end you receive three documents that turn the buyback into an item you can show: a data erasure certificate for every device, an ESG reuse certificate for the whole batch, and an invoice through the national e-invoicing system.
We have been repairing mobile phones since 2004, from our shop at Bulevar Arsenija Čarnojevića 91, Apt 3, 11150 New Belgrade. That matters here for one reason: we prepare the devices we buy for further use ourselves, so we do not have to count on a third party bringing them into sellable condition. That is why we can buy devices a pure reseller would decline — those with a broken screen, an exhausted battery, or a fault that can be repaired.
The programme came out of a real need, not out of a brochure. The first contract of this kind was with a pharmaceutical company in Belgrade that replaces fifty or more devices every year. Finding a buyer was not their problem — proving afterwards what had happened to the devices and the data was. Everything on this page about documentation came out of that conversation.
What is actually sitting in that drawer
Postponing the decision about old phones looks free. It costs in three places at once, and none of them shows up in a report until somebody asks.
Data that was never erased
A company phone is a business device before it is a phone: work e-mail, client contacts, calendar access, saved passwords, sometimes even the second factor for systems the employee no longer uses. When a device goes into a drawer without a formal wipe, that data does not disappear — it merely stops being tracked. The drawer becomes the place where the company keeps data it no longer accounts for, and the responsibility for it does not end because the device is switched off.
Written down to zero, still worth money
Phones are usually written off over two to three years, so after the write-off they sit at zero in the books. Zero in the books is not zero on the market: devices of that age still carry real resale value, and it does not fall evenly but in steps, with every new generation of the same model. Every month in the drawer is a month in which value drops, and the company gets nothing for that drop — no money, no reclaimed space, no closed record.
An ESG report with nothing behind it
More and more companies in Serbia report on their environmental impact — because of a parent company, because of tenders, or because of their own policy. Extending the working life of equipment is one of the few items where a small decision produces a measurable result, but only if a document confirms it. A device that was "sold somewhere" enters no report. A device with a reuse certificate does, together with an estimate of the emissions avoided.
The Viper Second Life programme
The name of the programme describes what actually happens to the devices. A phone written off by a company is not used up — on average it has served part of its working life, and the other part is still ahead of it, with a different user and different demands. The job of the programme is to make that handover orderly: the device changes owner with the data erased, with a record of who handed it over and when, and with a document the company can attach to a report.
The difference from an ordinary used-phone sale is that here a company is on one side, and a company cannot do business on someone’s word. So the programme is built around paperwork rather than around price: a contract, a handover record with every device in its own row, a per-device erasure certificate, and an invoice through the national e-invoicing system. Price is still the reason the deal happens, but the documentation is the reason it can happen again next year.
The programme covers phones and tablets from company use, whether or not they work. Devices with a damaged screen, a weak battery or a fault are not excluded from the list — they enter the offer at a lower amount, but they enter it. All we ask is that the list be honest: a device described as working that does not switch on at collection does not sink the whole deal, only its own line, and that in front of you, before signing.
Three ways to run the deal
The packages differ in how much precision you want and how much time you have. You do not have to choose in advance — you get a recommendation with the offer, based on your list, and the decision stays yours.
Per-device buyback
Every device is assessed individually and gets its own line in the offer.
You receive the offer as a table: model, storage, condition, amount per unit, then the total. This is the most precise package and it pays off best with a mixed fleet — when a few newer or better units sit alongside the older ones and would be undervalued in a flat price. If you decline a line, it drops out of the offer and the total is reduced; the rest stands. No device has to be handed over to obtain the assessment.
For mixed fleets and for companies that need a line-by-line record in accounting.
Fixed price for the whole batch
One amount for the entire batch, with no per-device assessment.
When a batch is large and uniform — the same or related models from a single procurement — assessing each unit takes longer than it is worth. In that case we quote a single amount for the whole batch based on the list, allowing for the fact that some units will be in worse condition than average. The advantage is speed: less paperwork, one line in the books and one date. The condition is that the list matches reality — if a material discrepancy in count or models turns up at collection, the amount is adjusted in front of you, before signing.
For uniform batches and for companies to whom finishing the job matters more than measuring it to the last dinar.
Employee purchase
Employees get the first chance to buy the device they were using.
In some companies the employee wants to keep the phone they used — out of habit, because of transferred data, or simply because they need it. In this package the company hands us the list, we prepare the purchase terms for employees, and the company circulates them internally. Devices that employees take are removed from the batch; the rest goes through package A or B, as you choose. For the company the administration is unchanged — one contract and one set of certificates — and the employee does not have to look for somewhere to service the device, because it is already with us.
For companies that want the fleet refresh to double as an employee benefit.
None of the packages carries a price on this page, and that is deliberate: the amount depends on model, storage and condition, so a published figure would be too high for part of the fleet and too low for the rest. The concrete amounts are in the offer you receive against your list.
How the buyback runs, step by step
Five steps from the list to the certificates. The deadlines stated here are the same ones written into the contract — there is no deadline we promise on the page but do not sign.
You send the list
Model and quantity are enough — a spreadsheet, an e-mail, or a message through the form on this page. You do not need to assess the condition and you do not need to prepare anything: do not reset or repair the devices before we agree, because either can take value away rather than add it.
Offer within 24 hours
Based on the list we send a written offer within 24 hours on working days — line by line for package A, as a single amount for package B. The offer is written and verifiable, so it can enter an internal approval procedure without being retyped. There is no obligation to accept and no cost if you decline.
Contract and collection
After acceptance a buyback contract is signed, with the device list attached. We collect the devices at your premises, against a handover record signed on the spot in which every device has its own row. From that moment there is a document stating where each device is — which is the difference from the drawer, where as a rule there is none.
Data erasure and payment
Every device goes through data erasure and sign-out from the previous owner’s accounts, individually and on record. Payment is made to the company account within 15 days of signing the contract. We do not ask for devices to be handed over before a signed contract and we do not make payment conditional on onward sale — the obligation is ours from the moment of collection.
You receive the certificates
The job does not end with the payment but with the documentation: a data erasure certificate for each device individually, an ESG reuse certificate for the whole batch, and an invoice through the national e-invoicing system. Those three documents are what turns the buyback into an item you can show — to internal audit, to a parent company, or to a contracting authority.
Three documents the company keeps
The money is one part of the job. The other part is that a year later there is an answer to the question of what happened to device number seven on the list.
Data erasure certificate
Issued per device, not per batch. It carries the model, the device identifier, the erasure date and the signature of the person who performed it. The reason for a per-device certificate is practical: a collective statement that "all devices were wiped" does not help when audit asks about one specific device from the list. A per-device certificate answers that without further correspondence.
ESG reuse certificate
It confirms that the devices in the batch were returned to use rather than discarded, and states an estimate of the emissions avoided. The estimate ranges from 50 to 80 kilograms of CO₂e per device and is calculated according to the ADEME methodology, which starts from the fact that most of a phone’s emissions arise in manufacturing rather than in use. That is an estimate under a methodology, not a measurement of the specific device — and the certificate says exactly that, because any more precise wording would be a claim we cannot prove.
Invoice through the e-invoicing system
The paperwork goes through the national e-invoicing system, as with any other transaction between legal entities in Serbia. For your accounting that means no document arrives outside the regular flow and no item has to be reconciled afterwards. The tax treatment depends on the seller’s status and is defined by the contract — we deliberately keep the wording neutral here and confirm the specific treatment before signing, rather than interpreting it in advance on a web page.
What it looks like in practice
A pharmaceutical company in Belgrade replaces fifty or more devices a year. Until they agreed terms with us, the old phones went into a storeroom and stayed there until there were enough of them for somebody to raise the question. Selling them was not hard; what was hard was that after the sale they had nothing with which to answer internal audit on whether the data had been erased and who had taken the devices.
Today the process is the same every year. Their administration sends a spreadsheet with models and quantities, they receive an itemised offer, we come for the devices and sign the handover record on the spot. Some of the devices are bought by the employees themselves, because that is easier for them than hunting for the same model in classifieds. What remains goes through the regular flow, and the company ends up with erasure certificates for every device and a single ESG certificate for the whole batch.
The content of this page is in effect transcribed from that arrangement. The three packages exist because three different needs came up inside the same company, and the three documents because each of them was asked for by somebody specific. If your company has a requirement not covered here, tell us at the outset — it is easier to write it into the contract than to resolve it after collection.
Frequently asked questions
What is the minimum number of devices for the buyback to make sense?
The programme is designed for batches rather than single devices — roughly from five units upwards. Below that we still buy, but through the regular flow for private customers, because one device does not justify a contract, a handover record and a set of certificates. If you have fewer than five, call us and we will tell you which route is faster in your case.
How is the price determined and why is it not on this page?
The price is determined by model, storage and condition, and for batches also by how uniform the fleet is. There are no figures on this page because any published number would be either too high for some devices or too low for the rest, and in both cases a promise the offer does not carry. Instead you receive a written offer against your list within 24 hours on working days, and only that offer contains amounts.
What happens to devices that are faulty or too old to buy?
Every fleet contains devices we cannot buy — faulty beyond the point of viability, or too old to have a buyer. We do not return them to your drawer: we hand them to an authorised electronic-waste operator, and you get a record for them as for the rest. Such devices have no buyback value and do not enter the offer amount, but they do enter the documentation — which is the point, because that is exactly the part of the fleet that otherwise stays unresolved.
How is VAT handled?
The tax treatment depends on the seller’s status and is defined by the contract. We deliberately do not interpret it in advance on this page: the specific treatment for your company is confirmed in writing before signing, so that your accounting has something to rely on. In every case the paperwork goes through the national e-invoicing system.
How long does payment take?
Payment is made to the company account within 15 days of signing the contract. The deadline does not depend on whether we have resold the devices in the meantime — the obligation is ours from collection. For a typical batch the whole process, from the list you send to the certificates, fits into two or three weeks, and most of that time as a rule goes to the client’s internal approval procedure rather than to us.
Who erases the data, and can we do it ourselves?
We do the erasure, per device, and issue a separate certificate for each. If your internal procedure requires devices to be wiped before they leave the building, that is entirely fine — tell us in advance and we will align with your procedure instead of duplicating it. We only ask that accounts are not signed out at random and without a record: a device left locked to a previous user’s account cannot change owner and its buyback value drops, sometimes to nothing.
Do you collect devices outside Belgrade?
We collect at the client’s premises in Belgrade. For companies outside Belgrade we arrange it case by case, depending on the size of the batch — for larger batches travelling makes sense, for smaller ones we organise shipping. Tell us the city and the approximate quantity and you will get a concrete answer rather than a guess.
Send us your fleet list
Model and quantity are enough. We send a written offer within 24 hours on working days, with no obligation and no cost if you decline it.
