TL;DR
A new billing workflow for agencies integrates retainers, usage-based fees, and one-off charges into a single invoice. This pilot aims to improve accuracy and efficiency in agency billing processes.
Agencies are beginning to pilot a new blended billing workflow that combines monthly retainers, usage-based fees, and ad hoc project charges into a single automated invoice. This development aims to address longstanding billing challenges faced by digital and AI services agencies, making invoicing more accurate and reducing revenue leakage.
The concept involves creating a billing workspace where an operations manager can define a client’s billing components—such as a retainer line, a usage meter, and one-time project charges—and generate a consolidated invoice automatically. This approach is currently being tested with a small group of eight agencies, each modeling a real hybrid-pricing client. The goal is to validate whether the system can produce accurate invoices comparable to manual, spreadsheet-based billing, and whether agencies are willing to adopt the new workflow.
The initiative is driven by the increasing complexity of agency billing, especially as more firms bundle AI usage costs into their retainer agreements. Existing subscription tools often cannot model a client who is billed part retainer, part metered, and part fixed-bid in a single invoice, creating manual reconciliation burdens. The new system aims to streamline this process, reduce errors, and save time.
The proposed minimum viable product (MVP) involves a tiered subscription model based on the number of billed clients and a small percentage of the invoiced volume. If successful, it could lead to broader adoption across the agency market, offering a more flexible and accurate billing solution.
Implications for Agency Billing Efficiency
This development could significantly improve billing accuracy and operational efficiency for agencies, reducing revenue leakage caused by manual errors and reconciliation delays. Automating a hybrid billing process aligns with the broader trend of digital transformation in agency operations, especially as AI integration becomes more prevalent. If agencies find the system reliable and easy to use, it could set a new standard for billing practices in the sector, enabling faster invoicing cycles and better revenue management.

Growing Complexity of Agency Billing Models
Agency billing has traditionally relied on straightforward retainer or project-based models. However, as agencies increasingly incorporate AI services and usage fees into their offerings, billing complexity has grown. Existing tools often fall short in modeling hybrid arrangements, leading to manual workarounds. This has caused errors, delays, and revenue leakage, prompting the search for more integrated solutions. The current pilot reflects a broader industry push toward automated, flexible billing systems capable of handling mixed models in a single invoice.
Earlier efforts focused on improving manual reconciliation or adopting custom spreadsheets, but these approaches are time-consuming and error-prone. The new workflow aims to address these issues directly by providing a unified platform for defining multiple billing components per client and generating accurate invoices automatically.

Unconfirmed Aspects of the Pilot Program
It is not yet clear how accurately the system can replicate manual billing in all scenarios or how willing agencies will be to switch from existing workflows. The pilot involves only eight agencies, and results may vary depending on client complexity and internal processes. Additionally, the long-term scalability and integration with existing accounting tools remain to be tested.
Next Steps for Validation and Adoption
The initial pilot will run for at least one month, during which agencies will compare automated invoices against their manual spreadsheets. Success will be measured by accuracy, time savings, and willingness to adopt the new workflow. If results are positive, developers plan to refine the platform and expand testing to more agencies. Broader rollout could follow within the next six to twelve months, depending on pilot outcomes and market feedback.
Key Questions
How does the blended billing model differ from traditional agency billing?
Traditional agency billing typically involves separate invoices for retainers, usage, and projects. The blended model consolidates all these components into a single, automated invoice, reducing manual effort and errors.
What are the main benefits of this new billing approach?
The primary benefits include increased billing accuracy, reduced reconciliation time, minimized revenue leakage, and improved operational efficiency.
Will this system work with existing accounting software?
Integration details are still being developed, but the goal is to create a platform that can export invoices compatible with common accounting tools. Scalability and compatibility are key focus areas for upcoming development.
When can agencies expect to adopt this new billing system widely?
If the pilot proves successful, a broader rollout could occur within the next year, with ongoing refinement based on user feedback and technical validation.
Are there any risks or downsides to this new approach?
Potential risks include the system not accurately capturing complex billing scenarios or resistance from agencies accustomed to manual processes. Ongoing testing aims to mitigate these concerns.
