Why a 13-week view

Same $15,000. Same quarter-end balance. A very different month.

A monthly P&L says the business is fine. A week-by-week view shows when the cash is actually there. Here is the same fictional agency with one invoice paid six weeks late.

Built for

Owners of established service businesses whose cash depends on when clients pay

Agencies, consultancies, studios and project-based firms. Typically 3 to 50 people, with payroll every two weeks and invoices on net-30 or longer terms.

“Our bookkeeper sends reports, but they look backward.”

Cash Command OS looks forward. It starts from today's balance and projects each of the next 13 weeks.

“I don't want another complicated tool.”

You enter a starting balance, expected payments in and bills out. A weekly update takes minutes, not an afternoon.

“Can I trust a forecast?”

A forecast is only as good as its inputs. The system shows every assumption line by line, so you can see why a number moved.

“Why pay $199 when free templates exist?”

Free cash flow templates give you a monthly total. Cash Command OS shows each of the next 13 weeks, flags the week cash dips below your reserve, and shows what a late client payment does before it happens.
