Does it work without internet?
Yes. Once linked, the register sells, charges, prints and keeps the shift without internet. You need internet in these cases:
- The first start of a new register (to link it to your account).
- Receiving orders from the online store.
- Charging with a link or QR.
- Sending the receipt by automatic email or showing the receipt QR.
- Google Drive backups.
Receipt emails that could not be sent wait in a queue for up to 24 hours.
What do I need to get started?
An Android 7 or later tablet or phone, and a food.yammbo.com account with the business approved by Yammbo. See What is Yammbo Food POS and Create your account.
How many tablets can I use?
You can join several tablets to the same location over Wi-Fi (register, kitchen or bar, waiter). They are all equals and keep selling even if another one is turned off. See Several tablets.
Do I need a printer?
No. The app works without a printer. If you want receipts, kitchen tickets or to open the cash drawer, see Printers and hardware.
Can I issue refunds?
There is currently no refund flow. If you need to undo a sale, void it: on the register screen tap the ⋮ menu > Void sale > Void the sale and type the reason (this needs the Void permission or a supervisor’s PIN). For a single product that was already sent to the kitchen, use Void sent item.
How do I update the app?
The app does not update itself. Download the latest APK, open it and install it over the existing installation:
https://github.com/yammbocom/yammbo-food-pos-releases/releases/latest/download/YammboFoodPOS.apk
There is also a «Descargar Yammbo Food POS» (Download Yammbo Food POS) button in the web dashboard, under «Dispositivos» (Devices). If you have several tablets, update all of them at once, or they will stop syncing with each other. See Install and update.
Where do I see the app version?
In Settings, at the bottom of the category list, as “Version 0.24” (the number changes with each update).
Do I need a food.yammbo.com account?
Yes, to use a new register. The only exceptions are a tablet that joins another register of the same location, a customer display and a backup restore.
Why can I not link the register?
It is almost always one of these reasons: the business has not been approved by Yammbo yet, there is no employee with the Owner role and a PIN in the web dashboard, or the 6-digit code has already expired (it is valid for 5 minutes). See Troubleshooting.
Why is my online store not receiving orders?
The store only accepts orders when a linked register at that location is on and online. If 3 minutes pass without a connection from the register, your customers see “This location is not receiving online orders right now.” Open the app on the tablet and check that it has internet. See Online orders.
How do I change my prices or my menu?
From the register, in the Menu section, or from the web dashboard. The menu is shared in both directions, so what you change in one shows up in the other. See Register and web dashboard.
What data is changed only on the web?
When the register is linked, the country, the tax percentage and the second currency with its rate are changed only on food.yammbo.com. Employees, roles and PINs are also managed in the web dashboard. See Settings.
What happens if I change the base currency?
Prices are not converted: C$120 becomes US$120. Past tickets will be shown in the new currency and the second currency is turned off. You can only switch to a currency with the same number of decimals.
Is my data backed up?
With the daily backup to Google Drive (around 3:00, 30 days are kept) or by exporting to a file. Payment link and QR keys are not included in backups. See Backups.
Can I charge by card or with a payment link?
The register records card payments (with an optional authorization number), transfers and cash. You can also charge with a link or QR using Tilopay, Pagadito, Stripe, PayPal or Mercado Pago; there, the payment is only recorded once the provider confirms it. Pagadito is the provider we have tested. See Charging and Payment links and QR.
Do reports use my country’s time?
Reports count the business day from 00:00 to 24:00 in Managua’s time zone (America/Managua), and it cannot be changed today, even if your business is in another country. See Customers and reports.
I forgot my PIN, what do I do?
Ask the owner to change it (in the register’s Staff section, or in the web dashboard if the register is linked). A PIN has 4 to 6 numbers and cannot repeat among active employees.
Can I use a second screen for the customer?
Yes, in two ways: a second screen connected to the tablet, or a second tablet joined over Wi-Fi. See Printers and hardware.
