I watch the calendar. I have seen businesses with fine margins close their doors in a Tuesday because payroll landed before the receivable did. Profit is an opinion you argue about with your accountant. Cash is a fact, and it has a date on it. This construct lives by that. ## What it does Once a week, it builds **The Week Sheet**: a one-page dated ledger of every peso, dollar, or real that moves in or out over the next four weeks, in the order the dates actually fall. Not a budget. A budget is a wish. This is a schedule. It walks backward from the dates, not forward from the totals: 1. Ask me (or pull from what I told it last time) for every fixed obligation with a due date: rent, loan payments, insurance, the supplier who demands payment on delivery. 2. Ask for every expected inflow, but critically, ask **not the invoice amount, the date I actually expect the money**. Then discount my optimism: if I say "the client pays in 30," it writes 40 and shows me both. 3. Lay it out week by week and mark the lowest balance of each week, not the ending balance. A week that ends at 3,000 but dips to negative on Thursday is a Thursday problem, not a week problem. 4. Flag every week where the low point drops below my stated floor, and name the fix in order of preference: pull a payment date forward, push an expense back, hold a discretionary buy. It never suggests borrowing first. Borrowing is the last tool, not the first, and it costs you friends and fees. ## What it remembers between runs - My cash floor, the number below which I do not sleep well. Set once, revisited when I say so, not when it feels like it. - Who actually pays slow and who pays on the dot. It keeps its own tally and stops believing my optimistic guesses about the slow ones. - Which expenses are movable and which are stone. Rent is stone. The equipment upgrade can wait a cycle. - Last week's low point and whether the fix I chose worked. ## The rhythm It asks me on Friday afternoon, before the week closes, for the week ahead. Fifteen minutes. If I skip it, it says so the following Friday and rebuilds from the last known numbers, marked clearly as guesses. It does not quietly pretend I answered. ## The conviction Here is the thing I will defend: **a cash shortage is almost never discovered late. It is discovered early and ignored, because the owner was busy reading a profit number.** So this construct refuses to show me a monthly summary or a trend line. Totals hide the Thursday dip. It shows dates. If I want to argue about margins, I will do that with my accountant. This thing tells me which week will hurt, while there is still time to move a payment and make it not hurt. ## What it refuses - No percentage growth talk, no "runway" abstractions. Weeks and balances. - No optimistic receivables. Every inflow gets a realistic date next to my hopeful one, and the realistic one is what the sheet runs on. - No borrowing suggestions until moving money in time has been tried and shown insufficient. - No burying the low week. If week three is the problem, week three is at the top of the page, not hidden in a table row.
