For independent grocers & small retailers

Every invoice checked. Every margin protected.

Supplier prices change constantly, and checking them against your shelf prices by hand costs hours every week. BKM Margin reads every invoice for you, checks it against your target margin, and tells you exactly what to charge to protect it — on your phone, in minutes.

Built by an independent grocer, for independent grocers — not a software company guessing at the problem.

The hours you don’t get back

A quiet price rise costs you every day it goes unnoticed

Nobody announces a price increase. The invoice total still looks about right. By the time it shows up in your margin, you’ve been absorbing it for weeks — on the products you sell the most. Checking every line of every invoice by hand, on top of running the shop, is the real cost. BKM Margin does the checking, so the only decision left is yours.

How it works

From delivery to decision, in four steps

1
Snap a photo
Photograph any supplier invoice on your phone, however it arrives — paper, PDF, or a stack of them.
2
It's read automatically
Every product, quantity and cost is extracted and matched to what you already stock.
3
Check your margin
See straight away which prices still hit your target margin, and which don't.
4
Update and move on
Apply the suggested shelf price and get back to running your shop.
More than a scanner

It doesn’t just read your invoices. It protects your profit.

Know your real margin
Cost checked against shelf price automatically, with UK VAT rules built in — not a guess.
Never manually check a price again
Photo in, structured line items out. You always see a review screen before anything is saved.
Catch price rises before they cost you
Every line compared with the last price you paid that supplier for the same product.
Compare suppliers automatically
See when a product you already buy is cheaper from a supplier you already use.
Built for how invoices actually look
Handwriting, faded print, invoices that run across several photos — all handled.
A full history, always searchable
Every invoice you've ever scanned, and everything it changed, in one place.

Who it’s for

Built for small, independent businesses — not big chains

If you buy from wholesalers and cash & carry suppliers, price your own shelves, and don’t have a procurement department to do it for you, this is built for you.

Early access

We’re onboarding a small group of shops first

We’re working closely with a handful of independent shops before opening up properly, so every store gets set up personally. Leave your details and we’ll be in touch when a place opens up.

No card, no commitment — we’ll email you when a place opens up.
