How to use Promo codes in Business Engine?
COS Business Engine allows Service providers to create and manage promotions designed to attract customers and boost sales. Promotions can include discounts, special offers, or limited-time pricing adjustments on services.
Overview
Service providers often want to hand out or publish promotion codes that can be entered at checkout.
When a valid code is entered, the corresponding promotion is automatically applied — simplifying the ordering experience and increasing conversion rates.
Promo codes can be:
-
Entered manually by the customer
-
Prefilled via URL (for example, when shared in marketing campaigns or referral links)
Subscriber Experience
Promo Code Entry
- A Promo Code field appears on the confirmation page during the ordering process.
-
Customers can enter a code and click Apply.
-
Once applied, the price updates automatically to reflect the promotion.
URL Prefill
-
A promo code can also be included in the order URL, which pre-fills the field automatically.
-
The same validation logic applies whether the code is entered manually or prefilled.
-
This functionality can be combined with referral URLs.
Removing a Code
-
Customers can remove a previously applied promo code at the order summary step, returning to standard pricing.
Promo Code Validation
When a customer enters a promo code, Business Engine automatically checks that the promotion exists (not case sensitive), is active within its date range, and applies to the selected service or service group. If any of these conditions fail, an error message is shown, but the customer can still proceed without applying the code.
Promotion Management
Administrators can easily create and manage promotions in Business Engine, with or without promo codes. Each promotion includes a Visibility setting that controls where it appears:
Not visible – only visible in the Administration Portal
Visible – visible to customers in the portal
Visible with code – visible in the portal and available for activation through a promo code
