From Excel to an Accounting System: When to Move — and When Not To
“Which is better?” is the wrong question. Excel does not fail when your file grows — it fails when more than one person owns the number. And chapter two is five cases in which staying is the right answer.

01 — Overview
Overview
Excel and an accounting system are not two things of one kind with one stronger. Excel is an open calculation tool that does what you write in it; a system is a constrained ledger that stops you from doing things on purpose — and the constraint is the product. So the useful question is not which is better, but what changed in your business.
And what you buy is not reports. A system buys you a trail: who entered what and when, and that you cannot erase it. What it does not buy is discipline, correct data, an understanding of your numbers, or time in the first three months — it takes that.
The book covers the whole move: the five signals, the full cost including the productivity dip and the cost of staying, requirements extracted from your own files, a chart of accounts built on decisions rather than a template, opening balances reconciled to an external source, a parallel period with a written exit condition, and one measure that cannot be fooled — is anyone still keeping their own Excel file?

06 — Questions, answered
Questions, answered
Will it tell me which system to buy?
It names no program at all. Programs change, get bought and shut down, and the decision does not change. What it gives you instead is better than a recommendation: requirements extracted from your own files, ten questions to ask any supplier — starting with “show me a transaction entered wrongly and then corrected”, which appears in no sales presentation — and two clauses to put in the contract before signing.
What if the answer is that I should stay on Excel?
Then the book did its job. Chapter two is five cases in which staying is right, and the most honest is that nobody owns the file — because a system does not create an owner, it becomes the same chaos inside a more expensive interface. And moving at the wrong time is more expensive than not moving: you pay, you disrupt your team, you lose two months, then quietly go back. The chapter also gives you four improvements that raise your Excel today.
Do I need an accounting background?
No. It is written for the owner who runs the file, not for an accountant. And it issues no ruling on a treatment, a classification or a return — on your chart of accounts, your opening balances and your timing it sends you to your accountant, who is part of the choice rather than someone who receives the result at the end of it.
How is it different from the ERP and data-migration books?
The ERP book covers a full business system — inventory, purchasing, human resources — and this one is about the financial ledger alone, which is what most businesses need first. The migration book carries the whole method for cleaning and moving data, and this one points at it rather than repeating it. Excel skill itself is the “Excel for Business” course, which this book assumes. What it adds is the decision and the transition: when, what it costs, and how to move without losing a year of your data.
