How it works
From intake to HMRC filing in four steps
Every device moves through an automated audit trail — from the second it arrives to the moment your accountant files the return.
Import & scan IMEIs
Under 5 minutes
Upload your existing CSV or scan device barcodes. Dual IMEIs, serials, models and grades are validated with zero duplicates from day one.
You get
Immutable device ledger + barcode labels
Log repairs & parts
As work happens
Replaced an OLED, battery or camera module? Parts and technician labour absorb straight into the device's landed cost before it ever gets listed.
You get
Repair cost absorption sheet
Sync sales channels
Live, always
List on eBay, Back Market, TikTok Shop and your counter. The moment a device sells anywhere, stock locks instantly across every other channel.
You get
Real-time multi-channel stock lock
File VAT & profit reports
One click, quarterly
The 1/6th margin tax on qualifying sales is calculated automatically — fees, repairs and purchase prices deducted — with MTD-ready accountant exports.
You get
HMRC Notice 718 MTD export
Generic ERPs treat phones like t-shirts.We treat them like financial assets.
Shopify apps, Vend and generic POS systems don't understand IMEI serialization, Notice 718 or repair absorption. MobileStock is engineered around the way resellers actually trade.
IMEI-locked device ledger
A permanent record from the instant a device arrives — IMEI, serial, grade, battery health, COGS, repairs and sale destination. Dual-IMEI tracking with automatic duplicate prevention.
98/100 PASSEDHMRC Notice 718 engine
The 1/6th margin tax applied automatically to every qualifying second-hand sale — with full audit trails, purchase invoices and one-click MTD exports your accountant will love.
Repair cost absorption
Parts and labour absorb into the handset's landed cost — never sell repaired stock at an invisible loss again.
Multi-channel stock lock
Sell at the counter; it locks on eBay and Back Market in 180ms. Zero double-selling, zero defect penalties.
sync latency 180ms
Supplier credit ledger
Purchase orders, returns, credit notes and Net 14/30 terms tracked in real time across every wholesale vendor.
True net profit telemetry
Marketplace fees, payment processing, shipping, repairs and margin VAT deducted live on every scan. Watch profit, VAT liabilities and stock aging update in real time — no more mystery numbers.

ROI & payback
Calculate your real monthly savings
MobileStock saves an average of 5 minutes per device — barcode intake, automatic Notice 718 maths and instant channel locks versus manual spreadsheet admin. Drag the sliders to match your volume.
Excludes recovered repair leakage (avg £600+/mo for repair shops) and overselling penalties — both eliminated by IMEI cost absorption and stock locks.
Verified UK resellers
Built and validated with real phone shops
Independent traders, multi-channel sellers and refurbishers who replaced spreadsheets with verifiable outcomes.
“Our techs logged screen swaps in WhatsApp. When a phone sold, we rarely knew if that OLED had cost £25 or £55. Now every part attaches to the IMEI — we stopped losing £600+ a month on unrecorded repairs.”
“Quarterly VAT used to be a multi-day nightmare, with £800 of extra accountant fees every quarter just to decipher our Excel margin sheets. MobileStock computes the exact 1/6th margin and exports MTD-ready in one click.”
“We had 2–3 accidental double-sales a month — someone buys in-store what sold on eBay ten minutes earlier. The cancellations were hurting our seller rating. Now the moment a device sells anywhere, it locks instantly.”
