From build to launch

  1. Install on the development store

    Every feature, free, for as long as it is a development store. No plan to choose and nothing to cancel later.

  2. Build and test the offers

    Create the discounts and promotions the brief asks for. In test mode a discount applies only to signed-in customers tagged dos-test, so you can check it in the real cart and checkout.

  3. Hand over, then go live

    At launch the client turns on DiscountOS Pro and every discount you built goes live exactly as you tested it: $14.90 every 30 days, 7-day free trial, on their Shopify invoice. Add it to your launch checklist so offers run from the very first order.

Why it holds up on a client store

  • Shopify’s own discount engine

    DiscountOS runs its discounts on Shopify Functions, so they apply in the cart and at checkout like Shopify’s own discounts.

  • More than Shopify’s 25 automatic discounts

    Shopify allows 25 active automatic discounts per store, and apps share that limit. DiscountOS Multi-offer runs many offers inside one automatic discount, so big catalogues and multi-market stores do not run out of slots.

  • Built for Shopify

    DiscountOS carries Shopify’s Built for Shopify badge, Shopify’s mark for apps that meet its quality and performance bar.

Questions agencies ask

Is DiscountOS free on a Shopify development store?

Yes. Shopify development stores and Shopify staff stores get every DiscountOS feature free, so you can build and test all of a client’s discounts before launch.

What happens when the store is handed over to the client?

At launch the client turns on DiscountOS Pro, and every discount you built goes live exactly as you tested it: $14.90 every 30 days with a 7-day free trial, billed on their Shopify invoice. There is nothing to rebuild.

Can I test discounts on the real storefront before launch?

Yes. A discount in test mode applies only to signed-in customers tagged dos-test, so you can check it in the cart and at checkout without real shoppers seeing it.

Who pays for the plan?

The store owner. Shopify bills the Pro plan on the store’s Shopify invoice, like any app charge. Every feature is included, with no order cap and no usage limits.
