Engineered freelance ops_
Cesium tracks your hours and bills them by the hour, the page or the month. It shows who still owes you and works out the tax to put aside, so you know what is safe to spend.

// PRINCIPLES
Four ideas Cesium is built on.
01 WORK IS THE INPUT. Log an hour, a finished page or a retainer month once. Invoices, reports and the tax estimate all read from that entry.
02 MONEY HAS THREE BUCKETS. Cesium keeps track of what you have earned, what clients still owe and what has actually been paid, down to an invoice paid in part.
03 TAX IS A SCHEDULE. Cesium estimates the tax for every week, half-month or month you choose, and counts income the way you are taxed: when it is paid, invoiced or earned.
04 HAND YOUR ACCOUNTANT ONE FILE. Export your profit and loss statement as a PDF, an Excel workbook or a CSV.
