Coupon codes with real guardrails — redeemable at the register and at self-order

Most coupon tools are either a blunt "take 10% off this ticket" button with no rules, or a separate marketing product bolted onto the side of the register. Opero puts real discount codes on the same order spine as your POS, kiosk, and QR ordering. You build a code once — percent-off or dollar-off — wrap it in guardrails that actually hold, and hand it out. Guests redeem it at the register or on the self-order screen, and every redemption is written to an append-only ledger you can trust. It's included on every plan, starting with Starter.

Percent-off or dollar-off, with guardrails that hold

A code is a discount plus the rules that keep it from being abused. In Opero you pick percent-off (1–100%) or a fixed dollar amount off, and then set the guardrails that matter for how you actually want the promo to behave. A percent-off can carry a maximum-discount cap so "20% off" never runs away on a large party, and no discount can ever exceed what the guest is spending — the math is clamped to the subtotal so a code can't drive a check negative.

• ✓Minimum spend — the code only unlocks once the subtotal clears the floor you set
• ✓Total-use cap — a global ceiling on how many times the promo can be redeemed, or leave it unlimited
• ✓End date — the code stops working automatically after the expiry you set
• ✓Max-discount cap on percent-off promos — so a big ticket can't blow the budget
• ✓Per-channel control — pick exactly which surfaces the code works on: POS, kiosk, online, QR, or any mix

Every one of these is enforced server-side at redemption, and it fails closed: if a code is inactive, past its end date, under the min spend, over a cap, or not allowed on the channel the guest is on, it simply doesn't apply — there's no path to slip a discount past the rules from a client. Validation runs against the authoritative server-computed subtotal, never a number the device sends up, so a percent-off is always taken on the same total it was checked against.

Redeem at the register — and now on kiosk and QR self-order

At the POS, a server applies a code when settling a dine-in check. The discount is allocated across the check's orders proportionally and each order's tax and total are recomputed, so reports that sum orders stay honest and the check still balances to the penny. On the self-order kiosk and QR flows, the guest types a code on the review screen and taps Apply — Opero re-prices the cart from the database and previews the exact discount before they commit, then claims it for real when the order is placed.

• ✓Per-channel control — allow a code on any mix of POS, kiosk, online, and QR; leave it open to all, or lock it to one surface
• ✓Kiosk and QR guests preview the discount on the review screen before paying — no surprise at checkout
• ✓The self-order path validates the code against the same server-priced subtotal the order will charge, so preview and final price agree
• ✓One promo per check at the register today — a check already carrying a discount won't stack a second one
• ✓If the last redemption slot races out between preview and payment, the order still stands at full price and the guest is told, rather than charging a discount with no ledger row behind it

One shared code, or a unique code per guest

A promo can be one shared code that everyone types — SAVE20 on a flyer or a table tent — or a set of unique one-time codes minted per guest. Unique codes are generated from an unambiguous alphabet (no look-alike characters) and default to a single redemption each, so you get exact per-guest tracking with no code-sharing. Which mode you want depends on the campaign, and you choose it when you build the promo.

On Growth and up, a promo attaches to a campaign so the code carries campaign attribution: a shared code is stamped to the campaign that sent it, and unique mode mints a distinct one-time code per recipient. Redemptions then roll up into a campaign ROI view — how many redeemed and how much discount was given, attributed back to the send — so you can see what an offer actually returned instead of guessing. (Unique per-guest codes are minted through this campaign send, so they come with the Growth campaign integration.)

An append-only redemption ledger

Every applied discount writes one row to an append-only redemption ledger — one row per applied discount, and no row is ever deleted. A redemption moves from applied, to settled when the sale is finalized (the point a one-time code is actually consumed, so an abandoned cart never burns it), to reversed on a void or refund. The claim that inserts the row and enforces the caps happens in a single atomic transaction, so two guests can't both grab the last slot on a capped code, and a committed claim always has its money applied. When a discounted check is voided or refunded, Opero restores each order's original tax and total from an exact snapshot taken at apply time — no lossy rounding — and frees the code back up.

Included on every plan, per location

Coupons and discount codes are included from the $99 per-location Starter tier — the same tier that runs your POS, ordering, KDS, and reservations — with unlimited devices and no per-device fees. There's no promotions module to upgrade into: building a code, setting its guardrails, and redeeming it at the register or on self-order is part of the base platform. Growth ($249) adds the campaign integration — attaching promos to sends, unique per-recipient codes, and campaign ROI — on top. All plans are per location, month-to-month, with no long-term contract.
