Free Business Tools

Plan profitable rates, forecast billable hours, enforce payment terms, and close clients faster with Zap Bill's free calculators and ready-to-use templates.

Running a freelance business or small service company means wearing many hats: you're the one doing the work, finding clients, managing projects, handling communication, and running the finances. Every hour spent on non-billable administration is an hour not spent on work that generates income. Zap Bill's suite of free business tools is built to compress the time you spend on the financial side of your business — from setting rates and planning capacity to creating proposals, sending invoices, and calculating late fees. Each tool in this collection solves a specific, recurring problem that independent professionals face: the hourly rate calculator helps you set rates that actually cover your costs and income goals rather than guessing based on what competitors charge; the billable hours planner helps you forecast realistic client capacity so you don't over-promise or under-earn; the proposal template gives you a professional framework for winning new projects; the late fee calculator helps you communicate and enforce payment terms without awkward conversations; and the contract template protects your business with clear scope and payment terms before work begins. Use them together to build a more profitable, organized, and professional business — and spend more time on the work you actually enjoy.
