Billing Stack Gravity
Billing Stack Gravity describes how the recurring revenue infrastructure an agency chooses for a client creates a gravitational pull that deepens the relationship over time. When an agency owns the billing layer, from invoicing to payment collection to tax compliance, it becomes operationally embedded in the client's cash flow. This is not about lock-in through contracts but through accumulated operational dependency. For example, an agency using Paddle as a Merchant of Record handles global tax compliance across 300+ markets, a burden the client would otherwise bear. Similarly, WHMCS automates hosting provisioning and invoicing, making the agency the de facto operator of the client's revenue engine. The strategic implication: agencies that master this stack can convert project work into long-term retainers, but they must balance the risk of platform lock-in against the client's evolving pricing needs.
