Billing considerations for an accounting application are discussed during which phase?

• A. Billing Phase
• B. Implementation Phase
• C. Documentation Phase
• D. Planning Phase

Answer: (D)

Billing considerations are established early in the Planning Phase because they define how the project will be funded and how the software will handle charges—things like pricing models, invoicing, milestones for payments, tax rules, and revenue recognition. Setting these details upfront guides the design and development work and helps prevent costly changes later. In contrast, Implementation focuses on building the system, Documentation creates manuals, and a separate Billing Phase isn’t a standard part of the lifecycle. So, the Planning Phase is the appropriate stage to discuss and decide on billing.
