Thirteen weeks of cash, receipts and payments, rebuilt every Monday from the bank feed and the open invoices. The low point is week 2, when the quarterly insurance premium lands.
Opening cash plus receipts minus payments, week by week. Receipts assume invoices are paid at the historical average of 23 days; payroll, rent and insurance are on their real dates.
Payments over the thirteen weeks. Payroll is two thirds; the rest is parts, rent, insurance, marketing and loan service.
Hold the two tech hires until week 6, when cash clears $430K two weeks in a row.
