Time tracking, invoicing, and tax prep that gets out of your way. Zapier, webhooks, and a REST API when you want to go deeper.
Here's what a typical workflow looks like for developers.
Start a timer from anywhere or quick-log hours after the fact. Assign to clients and projects in one step.
Set rates per client, per project, or per rate type (standard, overtime, rush). ClientCasa applies the right rate automatically.
Select a date range, pick the client, and generate. Minimum billing rules ensure you never underbill short sessions.
Zapier (8 triggers, 4 actions, 2 searches), webhooks (30 events, HMAC-signed), REST API with scoped keys, Slack and Discord notifications.
Ask natural language questions: "How much has Acme been billed this quarter?" or "Create an invoice for last week's hours."

Explore the demoFreelance developers need time tracking, invoicing, and tax-ready expense tracking — not a general ledger. Traditional accounting software requires bookkeeping knowledge and does not track billable hours. ClientCasa combines time tracking, invoicing, expense categorization, and Schedule C tax exports in one tool, without any accounting setup.
The choice between hourly and fixed-price depends on the project. Hourly works well for ongoing maintenance, support, and consulting. Fixed-price works for well-scoped projects with clear deliverables. The best practice is to track your time regardless of billing model so you know your effective hourly rate on every project. ClientCasa supports both models and calculates effective rates automatically.
Developers need a timer that starts with one click and does not require context-switching. A quick-log option for batch entry after focused work sessions is equally important. The tracker should assign hours to specific clients and projects, apply the correct rate automatically, and feed directly into invoicing. ClientCasa provides both a one-click timer and quick-log strip with automatic rate application.
Fixed-price gives clients budget certainty and rewards efficiency. Hourly protects you from scope creep and works well for undefined work. Many developers use fixed-price for new builds and hourly for maintenance. Either way, tracking actual hours is essential — it reveals your true effective rate per project and helps you price future work more accurately.
