Pricing Model Comparison
Fixed Price Contract

Best for well-defined, static projects. Risk of scope creep falls on agency unless protected by strict Change Orders.

Hourly Retainer (T&M)

Best for agile software development and ongoing marketing. Risk of scope changes falls on client; agency is paid for all hours worked.

1. Legal & Financial Dynamics of Fixed Price Contracts

Fixed price agreements set an absolute fee for defined deliverables. While attractive to enterprise clients, they require rock-solid functional specifications to prevent profit erosion.

2. Legal & Financial Dynamics of Hourly Retainers

Hourly retainers charge clients for dedicated developer time or actual logged hours. Contracts must define time-tracking protocols and monthly rollover limits.
