Design stage
Sell. Count the cash. Keep your data.
Simca is a point of sale and business manager being designed for small businesses in South America and other underserved markets. Offline-first. Cash-first. No telemetry. One local database for sales, stock, bookkeeping and the to-do list.
There is no download yet. This site tells you exactly what is built, designed, planned and undecided.
Principles
What the project promises to build around
Quoted from the project README. They are design principles, not audited properties.
No cloud required
Each store owns its data on its own devices.
Principles →PrivacyNo telemetry
No data collection. Updates are user-initiated and signed.
Read →CashCash-first
Yape and Plin recorded manually; cards only via phone Tap to Pay.
Cash workflows →ReliabilityReliability over speed
Redundancy and failsafes are worth a fraction of a millisecond.
Architecture →Scale of the plan
Everything it is planned to become
These are counts of planned catalog items and studied industries. Nothing is built.

From corner shops to Fortune 500 sectors

Open →Logistics and transportationCourier, parcel and postal services
Last mile, pickups and cash on delivery. Close fit.
Open →WholesaleWholesale food and grocery
