Overview
Every Offer in the DVM™ is built from two key components: a Plan and one or more Products. While the Plan defines how and when the consumer is billed, Products define what the consumer actually gets — the digital services they gain access to when provisioned with the Offer.Plan
Defines how the consumer is billed — the billing frequency, phases, price, and lifecycle start trigger. See Plan Types and Plan Configuration.
Products
Defines what the consumer gets access to — the digital service(s) included in the Offer, the tier of access they start on, and the tiers they can upgrade or downgrade to.
What is a Product?
A Product represents a digital service that a consumer gains access to when provisioned with an Offer — for example, a music streaming service, a video-on-demand platform, or a gaming subscription. Each Product in the DVM™ is structured into Product Tiers — distinct levels of service or value within the same product. For example:
When building an Offer, a Reseller selects which Product to include and specifies which tier the consumer starts on — this is the default tier. The default tier is the level of access the consumer receives when first provisioned with the Offer.
What are Available Product Tiers?
Available Product Tiers are the other tiers within the same Product that a consumer can move to during their subscription — without canceling and recreating their Offer. These are the tiers a consumer can upgrade or downgrade to from their current tier. Configuring Available Product Tiers on an Offer enables the upgrade and downgrade capability for consumers provisioned with that Offer. Without this configuration, consumers are locked to their default tier for the lifetime of the subscription. Each Available Product Tier has an associated Delta Price — the price difference between that tier and the default tier. Delta Prices are used to calculate:- The pro-rated charge issued when a consumer upgrades mid-cycle
- The pro-rated refund issued when a consumer downgrades mid-cycle
- The adjusted renewal price at the next billing cycle
Pro-rated charge and refund calculation applies only when the Billing & Charging capability is licensed. See Pro-ration for full details on how amounts are calculated.
How Products fit into the Offer Model
The diagram below shows how a Product with multiple tiers — a default tier and available tiers — sits within an Offer alongside the Plan.Default tier vs available tiers
Example — Netflix Offer with upgrade/downgrade
A Reseller creates an Offer for Netflix with Standard as the default tier, and Standard with Ads and Premium as available tiers. Product: Netflix
When a consumer is provisioned with this Offer, they start on
NETFLIX_STD at £17.99/month. At any point during their subscription they can:
- Upgrade to
NETFLIX_PREMIUM— a pro-rated charge of £5.00 × remaining days factor is issued immediately - Downgrade to
NETFLIX_STD_ADS— a pro-rated refund of £13.00 × remaining days factor is issued immediately
