Your shop's stock book and till, on your phone.

Free version

Everything your shop needs, nothing it doesn't.

The free version runs a whole business on your phone, offline: from receiving stock to giving change.

Stock that adds up

  • Products by unit, weight or volume, with variants (sizes, flavors) and presentations (single, 6-pack, box).
  • Stock entries by lot with cost, currency and expiry date.
  • Losses, damaged or expired goods, and physical counts that adjust stock for you.
  • Low-stock and expiry warnings, and a full movement history per product.

Sell in a few taps

  • Search or tap a product and it is in the cart.
  • Editable price, discounts and a warning when stock runs short.
  • Payment in several currencies with your own exchange rates and change calculation.
  • Full or partial returns that go back to the original lot.

Real profit

  • Sales, gross profit, losses, net profit and margin for today, the week or the month.
  • Sales by hour and by day, and your best sellers.
  • The cost of each sale comes from the lots it used, not an average.

Easy to learn, safe to use

  • A guided tour shows you each screen the first time, and you can replay it any time.
  • Step-by-step help inside the app, searchable and available offline.
  • Back up your data and photos to a single file you keep wherever you like.
  • In Spanish and English, with light and dark themes.

Calinv Premium

For when your business has more than one phone.

Everything in the free version, plus your team, your stores and an online copy. It still works offline.

500 CUP a month current price · paid via Transfermóvil

Sync that survives a dropped connection

  • Every phone in the store sees the same stock and the same sales.
  • Keep selling offline; when the connection returns, everything uploads by itself, with nothing duplicated or lost.
  • An online copy of your business, and product photos in the cloud (Wi-Fi only by default).

Several businesses and stores

  • Each store with its own catalog, prices, stock and sales.
  • Open a new store by cloning another store's catalog, without the stock.
  • The owner sees every store from their account.

Staff, each with their own account

  • Everyone signs in with their e-mail and password; after that they can also sign in offline on that phone.
  • Roles per store: owner, manager, seller and stock clerk.
  • Sellers don't see costs or profit and can't give discounts. Stock clerks handle stock entries, losses and counts.

Cash drawer check

  • Record the opening float in the drawer.
  • At closing, count the bills with the calculator and the app tells you whether the drawer balances, is over or is short against sales.
  • A history of drawer checks from every phone in the store.

Clear payments

  • Your payment and subscription history inside the app.
  • A reminder a few days before your month runs out.
  • Miss the date and nothing is deleted: after a few grace days sync pauses and every phone keeps selling.

Several phones per store

  • The counter, the stockroom and the owner's phone, all with the same information.
  • Your free-version business moves to Premium as a store, with all its data.

Privacy

Your data is yours.

In the free version everything stays on your phone. Only anonymous error reports are sent, and you can turn them off in Settings.

With Premium, your store's data is also kept on Calinv's own server so your phones can sync. It travels encrypted and is never sold or used for ads.

Read the privacy policy

  • No ads and no third-party analytics
  • Works without an internet connection
  • One-file backup you keep wherever you like

Ditch the notebook. Carry your shop in your pocket.

Calinv is free and available on Google Play for Android. Turn on Premium from the app whenever you need it.
