What did the year actually earn, which gear has paid for itself, and what is still owed? Reports read the jobs, quotes, invoices and inventory you already keep — nothing is entered for reporting’s sake, and every figure clicks through to whatever produced it.

Business overview, income tracker, expense tracker, profit & loss by job, outstanding invoices and client revenue. INCOME MIX breaks the year into the studio, equipment, you working a role — split per role — and misc, read from each quote’s own sections.
Earnings & payback, the gear status board, idle gear, and insurance & replacement values — read from the same inventory the gear lists are built from.

If your companies bill in different currencies, KitSlate will not sum them. All companies shows one band per currency, each totalling only its own — and says so.
No — and it says so rather than implying otherwise. It reads and writes their file formats: you export from them and drop the file in, and you export a CSV to take back. Nothing is fetched from them and nothing is sent to them.
Income falls back to day rates × days. The reports still work; they get sharper the more of the job is priced.
Yes. The company filter at the top of the hub applies to every report, and picking one puts every figure in that company’s currency.
Yes — CSV for a spreadsheet, or print the report as a PDF.
The sandbox carries a year of jobs, quotes and invoices, so every report has something real in it.
