Freelancers rarely lose money in one dramatic moment — it leaks through a stalled pipeline, an invoice nobody chased, a rate that never moved, and a calendar packed with the wrong work. The Freelancer Client Cash Planner is a one-file operating system for the business side of solo work. Inside: a client roster page with the fields that actually matter — rate, last contact, renewal date, outstanding balance, health score, and next action — plus a fill-in example; a five-stage sales pipeline (lead, discovery, proposal, negotiation, won) with entry and exit criteria for each stage so deals stop living in your head; an invoice aging table (0–30, 31–60, 61–90, 90+) with the escalation rule that moves each band to a specific chase script; four copy-ready payment chase emails — friendly day 7, firm day 15, final day 30, and the relationship-preserving freeze-work message — each written to keep the client relationship intact while money moves; a rate calculator that works backwards from income target to day rate and from day rate to the projects you must decline; the 13-week cash forecast that shows the crunch three weeks before it arrives and includes the five levers to pull early (invoicing cadence, deposit terms, retainer conversions, expense pauses, mixed receivables); retainer management rules — minimum term, rollover policy, what counts as overage, and the renewal conversation script; a profit-per-client mini-analysis so you know which of your clients actually pays you; a capacity planner in hours that protects deep work days from sales and admin; a weekly 20-minute money routine that replaces end-of-year panic; and a rate-increase letter sequence with timing, wording, and grandfathering options. Works with a spreadsheet, a notebook, or any tracker — no software required. Instant PDF download, personal-use lifetime license.
