## What is Chaos Billing?

Bill clients, track payments, and generate invoices from anywhere — Chaos Billing brings your data from Legal Billing on Windows to your iPhone and iPad, keeping everything in sync across all your devices.

YOUR CONTACTS, YOUR BILLING HISTORY, YOUR PRIVACY
Chaos Billing maintains an independent contact database and billing database with hourly timeslips, expenses and payments. Your data stays private — nothing leaves the app except through your own sync with ChaosHost. You're always in control.

FEATURES
• List of clients shows active balances and gives you a grand total below.
• Tap a client name to see their billing history. 
• Add hourly timeslips, add expenses, add payments — the balance updates instantly.
• Subtotal by type, matter (case or project), or staff, if desired
• Create invoices anywhere, ready to email, send through messages, or print
• Sync with Legal Billing on Windows through ChaosHost

REQUIREMENTS
Requires a ChaosHost account for cross-platform sync.
