Solution: Promo Engine

# Marketing clicks. Every POS *follows*, instantly.

Discounts, bundles, coupons, set promotions: every standard retail promo mechanic out of the box, segmented by customer group, shop, and region. Complex promotions extend through script validation and system hooks. The Promo Engine runs built into every POS or centrally as a standalone module, which puts it in your webshop too. Tuned for performance at scale.

## From a simple percentage discount to a scripted multi-criteria promotion.

Marketing clicks the promotion together, developers extend it by script when needed, and the engine delivers in milliseconds, whether it is one receipt or a hundred. The features below cover everyday promo work in SUMWARE.

- Discounts, bundles, sets: segmented

  ### Classic mechanics with surgical targeting.

  Percentage and fixed-value discounts, bundle promotions, set prices, buy-N-pay-M: every standard retail mechanic included. Restrictable to customer groups, individual shops, entire regions, or any combination. A click instead of code.
- Script validation per promotion

  ### When clicking is not enough, code steps in.

  Every promotion can be extended with its own validation script. Complex conditions, dependent rules, customer-specific logic: all without touching the core, all versioned inside the promotion record.
- System hooks into external systems

  ### The promo checks live: with CRM, ERP, loyalty.

  System hooks in the promo run call out to external systems: customer status from the CRM, stock from the ERP, points balance from the loyalty system. The discount is decided by the full context, not just the cart.
- On-the-fly vouchers in the receipt footer

  ### "€10 off your next purchase", printed right on the receipt.

  Beyond classic discounts, promo rules also generate vouchers during the transaction, printed directly in the receipt footer, redeemable immediately or within a set window. The customer leaves the store with a reason to come back.
- Standalone and built-in: two deployment modes

  ### Built into the POS. Or central, from the back office.

  The Promo Engine runs either as a built-in module inside every SUMWARE POS or as a standalone component served centrally from the back office. Mixed operation works too: standard stores local, flagship stores with special rules central.
- Omnichannel: POS and e-commerce on one engine

  ### The webshop sees the same promotion as the POS.

  The central component makes the Promo Engine omnichannel. Webshop, app, and external sales channels query the same service, get the same promotions, the same logic. Define a promotion once, live everywhere.
- Performance at scale

  ### 500 promotions × 100 items × hundreds of carts.

  The central engine is tuned for speed. Hundreds of concurrent carts with 100 items each and 500 simultaneously active promotions will not bring it to its knees. Stores never feel the load churning in the background.
- Scheduling and approval

  ### Click the promotion in the morning. Live by noon.

  Start and end times, weekdays, times of day, special dates: all defined as rules. Promotions go live with four-eyes approval, and the rollout to every POS happens within minutes, no redeploy needed.
- Stacking and conflict resolution

  ### Several promotions on one receipt: no drama.

  When multiple promotions match one cart, a configurable rule set decides: best discount, priority order, exclusive sets, or stacking. Conflicts are resolved before the receipt prints, not in the complaint conversation afterwards.
- Central analytics and reporting

  ### Which promotion performs? Which one eats margin?

  The central component delivers consolidated analytics across all channels: which promotion ran how often, in which store, for which customer group, at what margin, consolidated across all stores.
- ### Have a promotion in mind? We build it live.

  We demo the SUMWARE Promo Engine on a real promotion from your marketing plan: click it together, arm it, try it out on demo POS stations and in the demo webshop. No obligation, in 60 minutes.
