Spreadsheet bookkeeping gets more scorn than it deserves. For a brand new business with a handful of transactions a month, it is fast, free, and completely adequate.
It also has a defined ceiling, and staying under it too long costs more than moving early.
What a spreadsheet cannot do
The limitation is structural rather than about effort.
A spreadsheet records transactions as a list. Real bookkeeping is double-entry: every transaction affects two accounts, and the system enforces that they balance. That enforcement is what makes errors surface instead of accumulating.
In a list, a transaction typed once is simply there. There is no counterpart, nothing to disagree with it, and nothing to tell you when something is missing. Which is why spreadsheet books can be internally tidy and still wrong in ways nobody detects.
There is also no reconciliation in a meaningful sense. You can compare a total to a bank balance, but you cannot systematically identify which items explain a difference.
The five signals
1. You cannot produce a balance sheet. Most spreadsheet systems track income and expenses only. If you cannot say what you own and owe at a point in time, you have half a bookkeeping system — and the half you are missing is the one lenders and buyers look at first.
2. Payroll started. Payroll introduces liability accounts that accrue and clear on a schedule. Tracking withholding and remittance in a list, correctly, month after month, is where spreadsheet books most reliably break.
3. Inventory started. Inventory means cost of goods sold has to be recognised when items sell rather than when they are bought. That requires the two-sided treatment a list cannot provide, and without it gross margin swings with buying patterns rather than performance.
4. You sell into more than one state. Sales tax by state, tracked against separate thresholds with separate filing cadences, is a genuine data-modelling problem. Doing it in columns works until it does not, and the failure is a real liability.
5. Someone external needs your numbers. A lender, an investor, a buyer, or an accountant who has to file from them. Spreadsheet output invites scrutiny that proper statements do not, simply because it cannot be tied to anything.
Any one of these is usually enough. Two together is decisive.
What moving actually involves
It is a setup plus a cleanup, and it helps to think of it as two jobs.
The setup is the new file: chart of accounts built around your business, opening balances entered as of a chosen start date, bank feeds connected, rules configured conservatively.
The cleanup is the history. How much you migrate is a choice — the current year, so annual comparatives work, is a common answer. Everything, if the business is young. What you do not want is to migrate a partial period without deciding where the file actually begins.
The verification step matters most: after migration, the new file's balances must tie to the old records before you rely on it. A migration nobody verified is a migration that will surprise you at year end.
Where spreadsheets still belong
Not everywhere — and this is worth saying, because the pitch is usually "put everything in the software."
Spreadsheets remain excellent for analysis alongside the accounting file: job cost breakdowns at a level of detail no chart of accounts should carry, forecasting models, scenario work, budget-versus-actual by trade category.
The rule that works: the accounting file is the record; the spreadsheet is the analysis. Problems start when the spreadsheet is the record.
