Most business owners look at one number: the bank balance. It is the worst available guide, because it tells you about the past and says nothing about what is already committed.
Four reports, read together, tell you almost everything you need. IsiroBooks produces all four from the same double-entry ledger, so they always agree with each other.
Revenue minus costs over a period. The useful move is not reading it once but comparing periods — this quarter against last, this year against last. A rising revenue line with a faster-rising cost line is a business getting busier and poorer, and it is invisible if you only ever look at one month.
A snapshot on a date. Owners skip it because it feels like an accountant's document, but it answers a question the P&L cannot: is the business getting stronger? Profit that turns into unpaid invoices rather than cash shows up here and nowhere else.
Profitable businesses fail on cash. The cash flow report separates what you earned from what you actually collected, which is the gap most owners discover far too late.
Two lists, sorted by how overdue they are. Aged receivables is the single highest-return report in the product: it turns "I should chase some invoices" into a specific list of names and amounts, in order. Ten minutes on a Friday afternoon against that list will collect more than any amount of good intentions.
This is the part worth knowing. Accrual basis counts a sale when you invoice it. Cash basis counts it when the money lands. Your accountant will generally want accrual; most owners think in cash.
In IsiroBooks that is a toggle on every report rather than two separate products. You can look at the same period both ways in a few seconds, and the difference between the two figures is the story — it is exactly the money you have earned but not yet been paid.
A practical rhythm: aged receivables weekly, cash flow monthly, profit and loss quarterly against the same quarter last year, balance sheet whenever you are deciding something large.
