Free software to run your electronics business
Track every device by serial number and condition, handle repairs and trade-ins, keep your sales channels in sync, and run real books - free, on your own computer, with no per-user fee.
No per-user fees. No cloud lock-in. Your data stays on your machine.
The problems every electronics seller knows
Phones, laptops, parts and trade-ins pile up fast - and most software either can't keep track or costs a fortune per user.
Which unit is which?
Track every device by serial number / IMEI and condition - new, used, refurbished, for parts - so you always know exactly what you're holding.
What's my real margin?
Record what each unit cost (including repairs and parts) and see your true margin on every sale - not a guess.
Stock vs. your sales channels
Connect your online store so orders update stock automatically. No overselling the last unit across two channels.
Per-user pricing adds up
Celerp is free, with no per-seat fee - inventory, repairs, invoicing and proper accounting in one app.

Questions electronics sellers ask
