Spec docs and scope-of-work emails aren’t proposals. Prosperus gives developers and dev studios a way to present complex technical projects clearly — with phased timelines, tiered pricing, and a signature built in.
Scope creep starts at the proposal
Most scope creep doesn’t happen because clients are difficult. It happens because the deliverables were never written down clearly. “A website” means something different to you and your client until it’s listed line by line.
A Prosperus proposal with a detailed deliverables list and signed acceptance is the foundation of a project that doesn’t drift.
The retainer conversation
Developers who build without proposing ongoing maintenance leave money on the table and set themselves up for uncomfortable “can you just fix this quickly” messages six months later.
Building a support retainer into the proposal — with a clear scope and monthly fee — makes it a natural part of the engagement rather than an afterthought invoice.
