Plan the structure before you type
Start with paper or a spreadsheet. Write down the categories staff will tap first, then the items in each. Use the sections of the printed menu as a guide, but think about speed: a cafe till may put Coffee, Tea, Cold Drinks, Bakery and Food as five big buttons, even if the printed board splits them further. Eight to twelve categories is plenty for most places.
Give items short till names that fit on a button and read clearly on a kitchen ticket. 'Chkn Caesar' is fine on the till; the long description belongs on the printed menu and online ordering page.
Sizes are variations, options are modifiers
If an item comes in sizes or versions with different prices, it is one item with variations, not three separate items. A latte with small, medium and large variations keeps sales together and still prices each size correctly.
Everything else that changes how an item is made is a modifier: milk choice, extra shot, no onion, add bacon, well done. Group modifiers that belong together, mark a group required when the kitchen must know (a steak's doneness), and attach the same group to every item that uses it. Short, reused groups are faster for staff than long custom lists on each item.
Combos, specials and menus by time of day
Meal deals work best as combo products: one button with a deal price that includes a main, a side and a drink, with each part still showing on the kitchen ticket and coming out of stock. Daily specials can be a category of their own that you update each morning, or open-price items where the server enters the price.
If you run different menus at different times, such as breakfast and lunch, or a separate catering menu, set up separate POS menus rather than one giant menu. Staff switch between them, and each shows only the categories that apply.
Arrange for speed and test
Put the categories and items that sell most at the top left, where the eye lands first. Colour-coding buttons by type (hot drinks, cold drinks, food) helps new staff. Then test with the orders that cause trouble: a large table with modifiers, a combo with substitutions, a half-and-half pizza, an allergy note. Check both the bill and the kitchen ticket for each one.
Doing it in SeroPOS
You can build the menu in the app's Admin or in the web back office; both feed the same catalogue.
- Admin, then Categories: add categories and sub-categories; 'Hide in POS' keeps a category off the till.
- Admin, then Variation Groups: create Size with values such as S, M, L.
- Admin, then Modifier Groups: create groups such as Milk or Extras with prices.
- Admin, then Products: add each item with category, unit, tax and price, set type to 'With variations' where needed, and attach modifier groups.
- Back office, Products, then Add Product with type Combo for meal deals.
- Back office, Products, then Multiple Menus (POS Menus): create Breakfast and Lunch menus; menu pills appear in the app when there are two or more.
- In the app, long-press a product to set its button colour; in QSR Mode you can also drag buttons into a grid and set columns per category.
