Frequently Asked Questions
How do freelance developers structure invoices for long projects?
For multi-month projects, developers typically invoice in Agile sprints (every 2 weeks) or at key milestones (discovery, wireframes, development phases, QA, launch). A 25–50% upfront deposit protects against project abandonment. Maintenance retainers are billed monthly in advance.
Should web developers charge sales tax?
Web development services are not uniformly taxable. Purely professional services are often exempt, but delivering a tangible digital product, a downloaded application, or pre-written software may trigger sales tax obligations in many US states. Always consult a tax advisor for your specific situation.
