The Menu section is where you build what you sell. You need the “Menu and tables” permission. It has four tabs, each with its own counter: Products, Categories, Modifiers and Stations.

Create a category

  1. Go to Menu > Categories and tap Add category.
  2. Type the Name.
  3. Optional: choose a Default station. New products in that category start with that station. Tick Apply to the products in this category if you also want it applied to the existing ones.
  4. Leave Active on and save.

Category schedule

Use it to sell something only at certain hours (for example, breakfast).

  1. In the category, turn on With schedule.
  2. Tap Add schedule and, for each day (Sunday to Saturday), choose the Opens and Closes time. Remove schedule deletes it.
  3. If the closing time is earlier than the opening time, the category closes the next day (up to 06:00).

Outside its hours, the category looks gray on the register with the note Outside hours. If you add a product anyway, the register asks “(name) is outside its schedule. Add it anyway?” and you decide. The schedule is always evaluated in the Managua time zone (America/Managua), no matter which country you configured.

Schedule error: “The schedule is not valid. Use times like 07:00, and close before 06:00 the next day.”

A category with products can’t be deleted: “This category has products. Move them to another one or deactivate the category.”

Create a product

  1. Go to Menu > Products and tap Add product.
  2. Fill in the fields:
FieldWhat to do
NameUp to 60 characters.
PriceFor example 45 or 45.50. Shows the symbol of your base currency.
DescriptionUp to 300 characters.
Sold byUnit, Kilogram, Pound, Gram or Ounce (see Products sold by weight).
Type”Item” or “Combo”. It can’t be changed after the product is created.
CategoryPick an existing one or “New category” (created when you save).
BarcodeType it or tap Scan. Up to 64 characters and it can’t repeat on another active product.
PhotoTake photo, Choose from gallery or Remove.
Preparation stationWhich station it goes to (see Kitchen).
ActiveIf it’s off, the product isn’t sold.
Order (optional)To sort the list.
Product modifiersLink the modifier groups that apply (up to 20 per product).
  1. Save.

Form errors:

  • “Enter a valid price, for example 45 or 45.50.”
  • “The description can have up to 300 characters.”
  • “Another active product already uses that barcode.”
  • “The barcode cannot be longer than 64 characters.”
  • “The product was saved, but the photo could not be saved. Try again.”
  • If camera permission wasn’t granted you see No camera permission; you can type the code by hand.

Photos

The photo is shrunk automatically (maximum 512 pixels per side) to save space. If there is no photo, you’ll see “No photo”.

Finding products

In the list, use Search by name or barcode or the category chip (All). Each product shows “Sold in 7 days: (number)” and the “Combo” and “Inactive” tags where they apply.

Deleting a product

Tap Delete and confirm with Tap again to delete.

  • If the product already has sales, it isn’t deleted: it is deactivated (“The product already has sales, so it was deactivated instead of deleted.”).
  • If it is part of a combo, remove it from the combo first: “This item is a component of a combo. Remove it from the combo before deleting it.”

Products sold by weight

Under Sold by choose Kilogram, Pound, Gram or Ounce. The price becomes per that unit. When selling, the register asks for the weight: Type the weight in (name). Allowed decimals are 3 for kilogram and pound, 0 for gram and 2 for ounce.

Weight products and the online store

Your online store doesn’t show products sold by any unit other than “Unidad” (each). If you want to sell them online, create them as units.

Sold out

The register has no “sold out” switch. What you can do is deactivate the product (turn off Active) and turn it back on when you have stock again. The “sold out” marker that exists in the web dashboard for a location is not applied on the register.

Modifiers

A modifier is an option the customer chooses for a product (cooking point, extras, no onion).

  1. Go to Menu > Modifiers and tap Add group (“New modifier group”).
  2. Type the group’s Name.
  3. Set the Minimum (0 means optional) and the Maximum number of options that can be chosen. If they don’t add up you’ll see Check the minimum and maximum: the maximum must be at least 1, and the minimum cannot exceed the maximum or the number of options..
  4. Under Options tap Add option and type the name and the price Extra. Remove option deletes it. An extra can be negative (for example, “no cheese”).
  5. Save. The group summary reads “Elegir de X a Y, N opciones” (choose X to Y, N options).

Limits: 1 to 40 options per group and up to 20 groups per product. If a combination makes the price negative, the register warns “That combination of options gives the item a negative price. Check the menu extras.”

When selling, the register shows “Choose one option”, “Choose up to (number), if you like” or “Choose (number) to (number)”, depending on the group.

Combos

A combo bundles several items with choices.

  1. Create a product with Type = Combo.
  2. Add Combo groups with Add group and, inside each one, Add component.
  3. Each component can carry a price Extra.
  4. Activate the product when you’re done.

The combo price is the product’s price plus the extras of what the customer picks. A new combo is created inactive: “A new combo is created inactive. Add its groups and activate it when you edit it.”

Limits: 1 to 10 groups per combo and 1 to 30 components per group. A component is an item (never another combo), appears only once per group and its extra can’t be negative.

If a required group has fewer active components than its minimum, the combo shows as “Unavailable” on the register: “Some components of this group are sold out. The combo cannot be sold until enough are available.”

Stations

In Menu > Stations tap Add station. A station is a preparation place, such as the kitchen or the bar. Two come by default: Kitchen and Bar. See Kitchen.

No bulk import

The register doesn’t import or export the menu from a file. You create it product by product on the register or in the web dashboard, and when the register is linked the menu is shared with the web.

When the register is linked to food.yammbo.com, the menu is the same on the register and in your online store, and you can edit it in either place. The description (up to 300 characters) is shared too. Per-location pricing is changed only on the web: on the register it shows as “Precio en esta sucursal: X (se cambia en la web)” (price at this location, changed on the web).

The first time you link the register:

  • If the web is empty, the register uploads its menu.
  • If the register is empty, it adopts the web menu.
  • If both have products, There is already a menu on the web appears and you must choose (it can’t be dismissed without choosing):
    • Use the web menu: the register’s menu is replaced. Products that were already sold stay inactive to keep the history.
    • Upload this register’s menu: it is sent to the web once the web accepts it.

While it uploads you’ll see Uploading the menu: (number) of (number). To upload the menu, an employee with Menu permission must also exist on the web; otherwise: “To upload the menu, an employee with the Menu permission must also exist on the web.”
