The cash questions owners actually ask.
These are the questions owners actually ask me, answered the way I'd answer them across a table: the answer first, then the working, and I'll tell you where it doesn't hold. I'd rather tell you something you don't want to hear than something that isn't true. That's rather the point of the whole thing.
The research
Choosing a Xero app? What 26,128 reviews can and can't tell you.

What is a cash cushion?
How many months the business could keep trading if money stopped coming in: net cash divided by monthly cost base. Why that is not your bank balance, and how it differs from runway.

How to calculate net cash from a Xero trial balance.

The Xero question
How do I get a cash flow forecast out of Xero without building a spreadsheet?
Start with Xero Analytics, if your plan includes it: a cash projection up to 180 days ahead, worth switching on. What it tells you, what it does not, and the shorter route to a weekly cash answer.

The trap
Overtrading: why a profitable business can have no money in the bank.

The definition
What is deferred income?
A customer pays £120,000 up front: why the bank says 23 months of cushion and the truth is one. Deferred income as a liability, its release to the profit and loss, and how it differs from accrued income.

The five positions
The five cash positions a business can be in. Which one are you?

The data
About 4 in 10 companies in our Companies House sample had negative net cash.
We checked a random sample of 10,000 Companies House filings from June and July 2026. Of 2,980 checked trading companies filing non-micro accounts with usable cash and debtors, about 4 in 10 were below the line; of 3,275 with usable cash, nearly 2 in 3 held less cash than the creditors due within a year and 1 in 5 had £1,000 or less in the bank. What it means if that is you.

The finance role
What does a fractional CFO actually do?
A senior finance director for part of the week: planning, reporting and managing the cash. How that differs from your accountant, when an owner needs one and when they honestly do not yet.
