How to Forecast Cash Flow for Small Business

A projection of money coming into and going out of your business in a future period.

Cash Flow Forecast — in plain English

A cash flow forecast is a calendar of money. It shows every payment you expect to receive and every bill you expect to pay, week by week or month by month. It tells you whether you'll have enough cash to pay your suppliers and staff — before you find out the hard way.

Formula
Net Cash Flow = Total Cash Inflows − Total Cash Outflows

Why Cash Flow Forecast matters for your business

Most small businesses that fail do so not because they're unprofitable, but because they run out of cash at the wrong moment. A forecast lets you see a cash crunch 2-3 months before it happens — giving you time to arrange a credit line, delay a purchase, or push for faster payment from customers.

How far ahead should I forecast cash flow?

A 13-week (quarterly) rolling forecast is standard for most small businesses. It's far enough ahead to take action on problems, but short enough to be accurate. AskBiz can generate forecasts from 1 month to 12 months.

What data do I need to create a cash flow forecast?

Historical sales data, a list of recurring expenses (rent, salaries, subscriptions), and any known upcoming large payments or receipts. Upload a CSV of your transactions and AskBiz builds the forecast automatically.
