Refurbisher software: serial tracking, grading, and per-unit profit

Software for a phone or laptop refurbisher has to do three things. It tracks every unit by serial or IMEI from the day it arrives. It keeps the grade and the repair cost on that unit. And it still knows which unit sold on which channel. Rilk does all three: a unit keeps its serial from receiving to sale, repair costs follow it, and profit is per unit. It connects to Amazon and eBay on every plan and to Back Market on Pro, where serial tracking and grading also live.

You're probably dealing with

A pallet of mixed-grade returns where the "grading process" is a clipboard

A repair lane pulling from a parts bin nobody's counting

A "what did this unit actually cost" number that's parts plus labor plus freight plus regrading time plus overhead — nobody calculates it per unit anymore

Serial tracking that exists in the warehouse system but disappears the moment a unit lists on BackMarket or Amazon Renewed

A BackMarket grading taxonomy that doesn't map cleanly to your internal grades

A return that comes back weeks after sale with no way to tell whether it was your repair or a pass-through

An honest profit conversation about whether the rebuild category is worth it — without the data to have it

Here's what changes with Rilk

The regrading workflow treats every unit as a graded entity with a cost basis that travels with it. A unit comes in at grade D with a $40 cost, moves through repair with parts and labor logged, and exits at grade A with a real cost basis of $70 — so when it sells, the per-unit profit calculation is honest.

Serial numbers travel with the unit through every transformation. List the rebuilt unit on BackMarket, eBay, or Amazon Renewed via multi-channel sync, with the marketplace grading taxonomy mapped to your internal grades. When it comes back, scanning it shows the repair history and who did the work.

Returns on the refurbisher side routes on the question that matters: back to A-stock, back to the regrading lane, parts harvest, or write-off — each path keeping the cost basis attached. Per-unit profit reporting then shows profit per serial, by grade, by repair type, by channel.

Capabilities that matter most for you

Regrading workflow — cost basis stays with the serial through grade-in, repair, parts, labor, and grade-out

Returns — structured triage: warranty, regrading-and-relist, parts harvest, write-off

Multi-channel sync — list the same rebuilt unit to BackMarket, eBay, and Amazon Renewed without losing serial-level tracking

Reporting — per-serial profit, per-grade margin, per-rebuild-type ROI

BackMarket integration — native grading taxonomy mapping, listing flow, settlement reconciliation

Frequently asked questions

What's the best software for an electronics refurbishing business?

Look for one that tracks each unit by serial, carries grade and repair cost on the unit, and sells on the channels refurbished goods move on. Rilk does that on Pro, with Amazon, eBay and Back Market, and you can try it for 14 days free.

Can I track each iPhone by serial number or IMEI?

Yes. Every unit keeps its serial from receiving to sale, and a return comes back against the same serial.

Can I log repair and parts cost against a single unit?

Yes. Log the repair cost against the serial and the original cost follows the unit, so the profit on that unit includes what you put into it.

Which marketplaces can I sell refurbished units on?

Amazon, eBay and Walmart connect on every plan. Back Market and Newegg connect on Pro. Need one we don't connect yet? Tell us. A lot of what sellers ask for ends up in Rilk.

What happens when a refurbished unit comes back?

Received returns go back into sellable stock in the right bin. If it needs work, grade it again, log the repair and relist it under the right SKU with its cost attached.
