From raw daily numbers to a clear profit verdict
Four simple steps to turn what you already know about your business into the few KPIs that decide profitability.

How it works

Plug in your point of sale, accounting tool, or simply enter your revenue and costs. We support retail, production, and hybrid setups.
- 02
Pick the KPIs that matter
Margin, cash conversion, break-even point, cost per unit produced — choose the indicators that fit your business model.
- 03
Get your 90-second verdict
A clean dashboard tells you if you're truly profitable, where the leaks are, and what to fix this week.
- 04
Decide and act
Receive weekly recommendations and alerts so your numbers move in the right direction — without spreadsheet gymnastics.
Built for the businesses you actually run
Whether you sell behind a counter, build in a workshop, or do both — ShopByJLC speaks your numbers.
Retail shops
Boutiques, convenience stores, specialty shops. Track daily revenue, margin per category, and which week paid off.
Workshops & production
Bakeries, tailors, makers, repair shops. Watch cost per unit, scrap rate, and the margin behind every piece you produce.
Hybrid businesses
Cafés, salons, and shops that also sell services. See revenue split, mix performance, and break-even across both sides.
