See your tightest cash week before it arrives.
Thirteen weeks, built from your real accounts.
How it works.
River pulls your bank, Stripe, bills and payroll into one live Sheet, places every payment in the week it really lands, and names your low point, your runway and what to do before it.
Add hires and late payers
Or a round closing or a big purchase. River lists the signed offers and open invoices it already sees.
River reads every account
Payroll on its run days, rent on the 1st, and each customer timed by how late they usually pay.
Thirteen weeks at a glance
Opening cash that matches your bank, a chart of closing cash and three plain lines on top.
What you get.
- A 13-week forecast Sheet built with formulas, money in and out by type
- The lowest week, any week under two months of payroll and your runway, flagged
- A Sources tab behind every line, plus a late-payer version if you want one

Start in three steps.

A few things to know.
How does it know when customers will pay?
From each customer’s own history: how many days late they usually pay. Recurring items land on their real dates, and everything else follows your last eight weeks.
Which accounts does the forecast use?
Your bank or Mercury for 90 days of transactions, Stripe payouts and open invoices, QuickBooks bills by due date, Gusto or Rippling payroll, and Ramp or Brex card spend.
What does it cost?
It uses your plan’s AI credit, like everything else in River. It works from the bank, billing and payroll tools you already use.
