A chart of accounts is the vocabulary your business uses to describe money. Get the grouping right early, because rebuilding it later means restating every comparison you have.
A chart of accounts is the list of categories every transaction is filed under: the accounts that make up your balance sheet and your profit and loss. It sounds administrative and it is not — it decides which questions your accounts can answer. A business that lumps all marketing into one account can never say what a channel costs, and no amount of reporting later recovers information that was never captured.
The opposite failure is more common. Someone creates sixty expense accounts in the first month, and within a year half of them hold one transaction each, half the transactions are in the wrong one, and every report needs manual regrouping.
Number in blocks and leave gaps: assets 1000–1999, liabilities 2000–2999, equity 3000–3999, income 4000–4999, cost of sales 5000–5999, expenses 6000 upwards. The exact ranges matter less than leaving room — a scheme with no gaps forces new accounts to the end, and after two years the numbering tells you nothing.
The test is whether you would do something differently if the number changed. If knowing that software subscriptions cost more than expected would trigger a review, software deserves its own account. If you would never act on the split between stationery and printing, one account covers both. Where you need more granularity than the chart should carry — cost per project, per client, per site — the answer is usually a second dimension such as a tracking category or department code, not thirty more accounts.
Ettex Books is built around this: a chart of accounts structured the way accountants expect, double-entry journal entries with full debit and credit control, categories and auto-categorisation rules so recurring transactions file themselves consistently, attachments on any entry so the invoice sits with the transaction, multi-currency with rate tracking, instant search across all periods, and P&L, balance sheet and ledger export as PDF, CSV or XLS when your accountant asks. The written definitions — what belongs in each account — belong in Ettex Docs, and the sales side feeding revenue accounts sits in Ettex Invoices.
The boundary worth naming: Ettex Books does not come with a jurisdiction-specific statutory chart preloaded, does not file anything with a tax authority, and does not decide your accounting policies. It is a ledger with the structure you give it. Agree the chart with your accountant before you enter a year of transactions — that conversation is an hour, and skipping it is what produces the rebuild.
The structured list of accounts a business records transactions against — assets, liabilities, equity, income, cost of sales and expenses — usually numbered in blocks by type.
Often twenty to fifty. Enough to answer questions you would act on, few enough that everyone categorises consistently. Add accounts as costs recur rather than in anticipation.
In blocks by type with gaps left inside each block — for example assets from 1000, liabilities from 2000, income from 4000. The gaps are what keep the numbering meaningful as you add accounts.
Adding is easy and safe. Merging, renaming or renumbering breaks comparisons with prior periods, so do it at a year end and with your accountant rather than mid-year.
It should map cleanly to how your statutory accounts and tax return are presented in your jurisdiction. Starting from your accountant's standard chart avoids an annual mapping exercise.
Use a second dimension — a tracking category, department or project code — rather than duplicating accounts per project. The chart describes what was spent; the dimension describes what it was for.
A chart of accounts is a decision about what your business will be able to see. Start from the report you want to read, separate cost of sales from overheads, write down what belongs where, and keep it short enough that everyone files the same way.
Financial statements only make sense as a set. The income statement explains a period, the balance sheet a moment, the cash flow statement the difference between them — and the difference is where most businesses get surprised.
An accounting T chart is the simplest tool in double-entry bookkeeping and the fastest way to see whether a transaction was recorded correctly. Software hides it, which is exactly why it is worth being able to draw one by hand.
Management reporting turns the accounts into something a decision can be made from. The difference between a useful pack and an ignored one is commentary, not charts.
