Modifiers That Ring True: Menus, Modifiers, and Combos Without the Workarounds
A practical guide to building menus on NoPOS: modifier groups that price themselves, combos that ring up in one tap, and daypart swaps that never touch the dinner menu.
The NoPOS developer relations team writes practical guides for building on the NoPOS REST API — from first smoke test to production POS.
Every special request — extra shot, no onions, swap fries for salad — is margin walking out the door if the POS can't price it. NoPOS turns the menu into a system: modifiers that add up correctly, combos that sell themselves, and schedules that flip lunch to dinner on their own.
Build modifier groups that price themselves
- Attach required and optional modifier groups per item — size, milk, add-ons — with per-choice upcharges, so the check is right before the cashier even looks.
- Set min/max picks per group, so a sandwich can't leave with four premium add-ons for the price of one.
- Price consistently everywhere: the same modifier costs the same at the counter, the kiosk, and the online order, with no channel-specific surprises.
Sell combos in one tap
- Bundle an entrée, side, and drink into a single combo button with one price, and let guests upgrade any leg — large fries, premium drink — for a fixed delta.
- Keep food cost honest: every combo leg still decrements its own inventory recipe, so theoretical cost stays accurate.
- Run limited-time bundles — game-day box, family pack — with start and end dates, so promos expire on their own instead of lingering on the screen.
Let the schedule flip the menu
- Assign items and price levels to dayparts — breakfast wraps out at 10:30, happy-hour pricing in at 4 — and the POS swaps automatically.
- 86 an item once and it disappears from every channel at once, with auto-firing low-stock alerts before the next rush.
- End of week, per-item and per-modifier sales roll into one report, so the dogs come off the menu and the stars get their combo.
