Step-by-step help for each part of Mercavo POS. If your question isn’t covered here, email us.
Set up your store
Open the app. On a new install, choose Start fresh, or choose Restore from backup to bring back a store you saved.
Open Settings, tap Store and type your store’s name.
Pick your currency from the list. It saves as soon as you choose one.
The Appearance section in Settings turns Dark mode on or off and shows the catalog as a grid or a list.
Changing the currency only changes the code shown with each amount. It doesn’t convert your prices.
Add products and services
Open Products and tap the round + button.
Choose Product or Service. Services have no stock or barcode, so use them for repairs, load, printing or labour.
Add a name and a price. A photo, the cost, a category, a barcode (type it or scan it) and a SKU are optional. To give a product stock, tap + beside Stock.
Tap Add product. To change a product later, tap it in Products, edit it and tap Save changes.
Products can’t be deleted. Set one to Inactive while editing it instead. It disappears from Checkout, and its past sales stay in History.
Categories, payment methods and quick amounts
In Settings, open Categories and add one with the + button. If you delete a category, its products move to Uncategorized.
In Settings, open Payment methods. Cash, Mobile Wallet and Card are always there, and you can add your own, like your bank or your e-wallet’s name.
In Settings, open Quick amounts. These are the +20, +50 and other keys on the Payment screen. Exact is always there.
Anything you delete asks you to confirm first.
Ring up a sale
On Checkout, tap a product to add one. The blue badge shows how many are in the sale.
Find items with the search box, the category chips or the scan button. The camera reads common barcodes, including QR, EAN-13, UPC-A and Code 128.
Tap the item count next to Charge to see the sale. You can change quantities, remove a line or clear the sale there.
Tap Charge.
Take payment
Pick how the customer is paying: Cash, Mobile Wallet, Card or a method you added. It’s saved with the sale, and the keypad works the same for all of them.
Payment opens with the exact total filled in, so an exact payment is a single tap on Confirm.
If the customer pays more, tap Exact or a quick amount (they add up), or type the amount they gave you. After Exact or a quick amount, the next key you press starts a new amount.
The screen shows the change to give, or how much is still due. Confirm works once the amount covers the total.
Order bills
After you tap Confirm, Sale complete shows the change to give. Tap View bill or Download bill.
Download bill makes a PDF and opens the share sheet, where you can save it, send it or print it.
To add your own lines, like a tax ID, an address or a thank-you, open Settings and tap Order bill. The preview updates as you type.
An order bill is informal. It is not a tax receipt.
Keep track of stock
Every sale takes its items off their stock.
To add stock after a delivery, open the product in Products and tap + beside Stock. Type the quantity and, if you like, a note. Stock history below it lists each addition and sale.
Low stock alerts mark an item as Low when 5 or fewer are left.
An item with nothing left shows Sold out and can’t be added until you add stock.
Services never have stock.
History and reports
History lists every sale by day for Today, 7 days, 30 days or dates you pick. Tap a sale to see its items, its payment and its order bill.
Completed sales can’t be edited or voided, so History stays accurate.
Reports shows revenue, the number of sales, the average sale, your top products, payment methods and how the period compares with the one before.
The download button in Reports saves the range as an XLSX spreadsheet. On iPhone, iPad and Windows, the Backup & restore page in Settings can also export your sales as a CSV file.
Back up and move to a new device
In Settings, open Backup & restore and tap Export backup. You get one file with your products, photos, sales and settings, named with the date and time.
Keep the file somewhere other than the device, like Files, iCloud Drive, Google Drive, an email to yourself or a computer.
On the new device, install Mercavo POS and choose Restore from backup on the Welcome screen. After that, use Backup & restore in Settings instead.
Restoring replaces everything in the app, so it asks you first. A backup restores on the same kind of device (iPhone and iPad, Android, or Windows), not across them.
Remove Ads Forever
Open Settings. The card at the top is Remove Ads Forever. Tap Remove Ads and your app store handles the payment.
On a new device or after reinstalling, tap Restore on the same card while signed in to the store account you bought it with.
Restoring a backup doesn’t restore the purchase. Only the store can do that. Refunds go through Google Play or the App Store. On Windows there is nothing to buy in the app.
Ads and the internet
The free version shows a full-screen ad when you come back to the app. It shows at most once every 10 minutes, and never while an order bill is on screen.
The free version needs an internet connection. Without one you’ll see No internet connection. Reconnect and tap Retry, or remove ads to use the app offline.
With Remove Ads Forever there are no ads and you don’t need a connection. Windows has no ads and always works offline.
On Windows
Mercavo POS for Windows is a one-time purchase from the Microsoft Store. It has no ads and always works offline. Every action has a shortcut, and a USB barcode scanner types straight into search, so scanning a code adds the product.

Troubleshooting
Something not working?
Fixes for the most common problems.
Allow camera access for Mercavo POS. On iPhone and iPad, open Settings, then Privacy & Security, then Camera. On Android, open Settings, then Apps, then Mercavo POS, then Permissions. On Windows, open Settings, then Privacy & security, then Camera. You can always type a barcode instead.
The free version needs a connection while ads are on. Reconnect and tap Retry. The app also checks again by itself every few seconds. To sell offline, tap Remove ads to use offline.
It may be Inactive (look under Inactive in Products), hidden by a category chip, or filtered out by the search box. Sold-out items still show, but you can’t add them.
Open Settings and tap Restore while signed in to the store account you bought with. A backup never includes the purchase, and a purchase made on Apple doesn’t move to Google Play, or the other way round.
Choose the backup file itself: a .mercavobackup file on iPhone and iPad, or a .zip on Android and Windows, made by Mercavo POS on the same kind of device. If it still won’t open, export a new backup on the old device.
Download bill opens the share sheet. Choose Save to Files, a printer or an app. On Android, pick a files app or your printer’s service. On Windows the PDF is saved where you choose.
Mercavo POS makes informal order bills, not tax receipts. You can add your tax ID or permit number under Order bill in Settings. If your country requires registered receipts, use a registered device for those.
Uninstall the app, or clear its storage in your device settings. Everything is stored only on the device, so that removes it. Export a backup first if you might need it.
Still stuck?
Email us and include your device (for example “iPhone 15” or “Pixel 8”), the app version from the bottom of Settings, what you tapped, and a screenshot if you can. We read every message.
