Buying and selling refurbished phones in your repair shop: how to set it up

Almost every repair shop has the same problem: it depends on the flow of customers bringing in broken phones. When volume drops, so does the till. Buying and selling refurbished phones breaks that dependency: you buy a used handset at a good price, make it like new with the parts and skills you already have, and sell it with margin. It's your own product, with stock you control, that doesn't rely on anyone breaking anything.

1. Why refurbishing fits your shop perfectly

A repair shop starts with an edge over any second-hand seller. The difference comes down to three things you already have and that cost others money:

• Parts and suppliers: you already buy screens, batteries and flex cables wholesale. Refurbishing a phone costs you the part, not what you'd charge a customer for it.
• Technical knowledge: you can tell a board fault from a loose connector. You can cheaply buy a unit others write off as "won't turn on" and fix it in 20 minutes.
• Downtime: the slow shop hours, when no work comes in, turn into productive time refurbishing stock. You fill the gaps with margin.

Add to that the fact that the customer bringing in an old phone to fix is the perfect candidate to sell a refurbished one to, or to buy theirs from when they decide to upgrade. The new line feeds off the one you already have.

2. How to appraise a used phone (buy price)

This is where margin is won or lost. Buying a handset badly is paid back later on the resale. The appraisal should be a small ritual, not a "here's 100 and we're done". Always work from a market reference: check what that same model, in that condition, refurbished, sells for, and work backwards from there.

What to check before quoting a price

• Screen condition: scratches, dead pixels, OLED burn-in, touch that responds across the whole surface.
• Battery health: the maximum capacity percentage tells you whether you'll have to replace it (a cost you deduct from the buy price).
• Locks: check there's no account lock (iCloud/Google) and that the IMEI isn't reported or stolen. Without this, don't buy.
• Key functions: cameras, speakers, mic, Face ID/fingerprint, charging, buttons, signal. A 5-minute test saves you surprises.
• Chassis and moisture: knocks, bent frame, liquid indicator. A water-damaged phone is a risk, appraise it as such.

The mental formula is simple: resale price − cost of the parts it needs − your target margin = the most you can pay. If a model resells for €220, needs a battery (€18) and you want €60 of margin, your buy ceiling is around €140. Anything you negotiate below that is extra margin.

3. The process: inspect, clean, repair and grade

Refurbishing isn't just "clean and sell". An orderly process gives you a consistent product and a reputation that translates into people paying more without haggling.

1. Full diagnosis: repeat the appraisal tests calmly and note what needs touching.
2. Repair: replace anything that doesn't meet your standard. A battery below a certain threshold, scratched glass, a failing button. Decide which parts you use (OEM or aftermarket) and be consistent by grade.
3. Deep clean: speakers, ports, chassis. A spotless phone sells itself.
4. Reset and final test: secure data wipe of the previous owner, format, and one last round of testing everything.
5. Grading: A (like new, minimal marks), B (visible use but perfect working order), C (clear marks, more aggressive price). The grade organises your display and anchors the price.

4. Setting the sale price and margin

The sale price is set by the market, but the margin is set by how well you bought and repaired. Think in terms of the phone's real total cost, not just what you paid for it.

That's the number that matters: not the €95 gap between buy and sell, but the €60 real left after parts, your time and consumables. A 20–35% margin per handset is healthy to start; on high-end or in-demand models you can aim higher. And remember: each unit can also generate accessories (case, protector, charger) in the same sale, which lift the ticket at almost no cost.

5. Refurbished warranty

Selling a refurbished phone means giving a warranty, and here it pays to be serious: it's what separates you from the informal seller and what justifies your price. The exact duration and conditions depend on your country's regulations, so find out what you're legally required to provide and set your commercial policy from there.

What is universal is how to handle it well:

• Put it in writing: the term, what it covers and what it doesn't (for example, impact or liquid damage after the sale).
• Record the IMEI of every handset sold and link it to its record: you'll know instantly whether a returning phone is yours and under warranty.
• Keep the history of what you did to the unit. If it comes back, you know which parts it carries and from when.
• Be clear about grade and condition: an honest description reduces returns and arguments.

6. How to control stock without the mess

The point most shops underestimate. With five or six handsets you keep it in your head; with thirty, you start losing track of what you have, in what grade, what each one cost you and which have been sitting for months eating your capital. Refurbishing lives on control: what you bought, for how much, what you put into it, what you sell it for and the real margin it leaves.

This is where your management software does the heavy lifting. TekPair lets you register each handset as a stock product, with its IMEI, its real cost (purchase + parts + labour), its grade and its sale price, and record the warranty linked to the unit when you sell it. You always know what you have, what's rotating and the real margin your refurbished line is actually leaving, without loose spreadsheets.

Setting up refurbished buy-and-sell doesn't require opening another business or changing yours: it's one more layer on top of what you already do. Start small, with two or three models you know well and move quickly, look after appraisal and warranty, and let the margin tell you when to scale.
