Losing a project because of a messy quote is a tragedy, but writing a single line of code without an upfront deposit is a business failure.

Frequently Asked Questions
What is a standard upfront deposit for app development projects?
Veteran developers typically require a 25% to 50% upfront deposit to secure the project timeline and cover initial discovery and architectural setup.
How do I handle clients who request features not included in the original estimate?
Reference the original line items in your estimate and explain that the new request requires a signed 'Change Order' or a separate mini-estimate to protect the project timeline.
How can I ensure my estimate is legally protective?
Include a section for 'Assumptions and Dependencies' where you list what you need from the client (like API documentation) to meet the proposed delivery dates.
