When you link a register to your food.yammbo.com account, the register and the web dashboard share part of their information. That way you edit the menu, employees or business details in either place and it looks the same in both. To link, see First start and linking.
Only the linked register talks to the web. The other tablets at the location receive everything over Wi-Fi from it (see Several tablets). The register checks for changes and orders with the web every 10 seconds.
What is shared and in which direction
| Data | Direction | Notes |
|---|---|---|
| Employees, roles and PINs | Web to register, and register to web | Employees marked “Only on this register” are uploaded once. Maximum 100 employees. |
| Business details (name, tax ID, address, phone, receipt footer, customer language) | Both directions | The last change wins. |
| Country, tax and second currency | Web to register only | Read-only on the register. |
| Base currency | Both directions | Only currencies with the same decimals; prices are not converted. |
| Logo and cover photo | Both directions | The cover photo only appears with the register linked. |
| Menu and product descriptions | Both directions | The description allows up to 300 characters. See Menu. |
| Customers | Both directions | Matched by phone. |
| Payment methods | Both directions | A single list; the last change wins. |
| Online store orders | Web to register | The register answers the web (accept, reject, statuses). See Online orders. |
What is changed only on the web
With the register linked, these fields show on the register with the text Change it at food.yammbo.com and can’t be edited there:
- Country.
- Tax percentage and whether it is included in the price or added on top. (The tax name can still be edited on the register.)
- Second currency and its exchange rate. The register reads The base currency is changed here. The second currency and its rate are set at food.yammbo.com.
- Per-location price of products: on the register it reads “Precio en esta sucursal: X (se cambia en la web)”.
Employees, roles and PINs are managed in the web dashboard (the “Equipo” (Team) section, “Empleados del POS” tab). On the register you’ll see “Employees, roles and PINs are managed in the web dashboard. Employees that only exist on this register are never deleted.” and the Update employees button.
These dashboard features exist only on the web: promotions and coupons, reviews, delivery zones, location opening hours, team and billing. See Create your account.
Still editable on the register: business name, tax name, tax ID, address, phone, receipt footer, customer language, base currency, payment methods, logo and cover photo.
Conflicts: the last change wins
If the same piece of data (for example, the address or the payment methods list) is changed on the register and on the web, the last saved change wins. If two people edit at the same time on the web, the dashboard warns «Alguien más cambió esto mientras lo editabas. Recarga la página y vuelve a intentar.» (someone else changed this while you were editing; reload and try again).
Customers are matched by phone: if the phone already exists on the web, the register’s customer merges with the web one and the register notes Customer joined with the one that already existed on the web: (name).
Without internet
The register works without internet to sell, take cash, card and transfer payments, use the kitchen and print. What you can’t do without a connection:
- Receive online store orders. After 3 minutes without a connection, your store stops accepting them until the register is back.
- Charge by link or QR.
- Receipts by QR and by email (email waits in a queue and is discarded after 24 hours).
- Get menu, employee or business-detail changes to the web (they are sent when the connection returns).
On the Online account card (in Settings > Location and devices) you see the link status: “food.yammbo.com/…”, “Linked on (name)”, “Last connection with food.yammbo.com: (number) minutes ago” and “Web orders: receiving”, “Web orders: checking the connection” or “Web orders paused: no connection”.
Unlinking and revoking a register
- Unlink (on the Online account card) only forgets the link on that tablet. Receipts that were waiting for a connection are discarded.
- For the server to stop accepting the register, revoke it on the web dashboard too: “Dispositivos” (Devices) > Remove > Yes, remove («Sí, quitar»). The tablet loses access immediately.
- If the server unlinks the register, you’ll see “The server unlinked this register (revoked in the panel or invalid token). Link it again.”
- Link again: the tablet’s sales, products and employees are not deleted; only receipts waiting for a connection are discarded.
Suspended account
If Yammbo suspends your restaurant, the dashboard shows «Tu restaurante está suspendido.» (your restaurant is suspended), your page and new orders are turned off and the dashboard becomes read-only. Write to support@yammbo.com or use the “Hablar con Yammbo” (talk to Yammbo) button in the dashboard.
