[Web] Ledgerline - free invoicing/business tools for freelancers

Live at rahmanov.org, no signup needed. Ledgerline is a set of free browser-based tools for freelancers, invoices, receipts, contracts, time tracking, and expense/tax estimates. Nothing gets uploaded to a server, it all runs in your browser. I'm the solo dev, would genuinely love feedback on what's confusing, what's missing, or what would make you actually switch from your current tool.
