How to set up a chart of accounts
A chart of accounts you have to rebuild in year two was built wrong in year one. Here is how to set one up that actually scales.
Why chart of accounts setup is hard to get right
A chart of accounts is easy to set up badly: too few accounts and every report is a blur of "Miscellaneous Expense"; too many and every entry becomes a guessing game about which of twelve similar accounts to use. The real difficulty is designing for reports you have not built yet.
Where teams get it wrong
- Creating a new account for every new vendor instead of using dimensions like department or project.
- Copying a chart of accounts from an unrelated business instead of one built for your actual model.
- No consistent numbering convention, so accounts are hard to sort or group by type.
- Mixing accounts and reporting tags - trying to make the chart do the job dimensions should do.
- Never revisiting the chart after initial setup, even as the business changes shape.
The Chart of Accounts Setup Framework
- 1Start from a template - use an industry-appropriate starting structure instead of a blank sheet.
- 2Number by type - assign number ranges to asset, liability, equity, revenue, and expense accounts consistently.
- 3Keep the account list lean - model most day-to-day variation with dimensions, not new accounts.
- 4Add dimensions for slicing - tag transactions by department, project, or location instead of creating parallel account trees.
- 5Review annually - revisit the structure as the business grows, without renumbering existing history.
How Fintra sets up your chart of accounts
| Step | What Fintra does |
|---|---|
| Start from a template | COA templates give you an industry-appropriate starting chart instead of a blank ledger. |
| Number by type | The general ledger enforces consistent numbering ranges by account type out of the box. |
| Keep the list lean | Dimensions handle department, project, and location detail so the account list itself stays manageable. |
| Add dimensions | Transactions tag by dimension at entry, so reports can slice by department or project without new accounts. |
| Review annually | Multi-period reporting lets you compare structure changes over time without losing prior-period history. |
Migrating from QuickBooks or Xero maps your existing chart of accounts automatically, so switching tools does not mean rebuilding your structure from scratch.
Your chart of accounts checklist
Confirm these before you go live
- Pick a template appropriate to your industry, not a generic default.
- Assign consistent numbering ranges by account type.
- List the dimensions you need - department, project, location - before adding new accounts.
- Merge any near-duplicate accounts created early on.
- Document the intended use of every account for future hires.
- Set a policy for who can create new GL accounts.
- Schedule an annual structure review as the business changes.
Frequently asked questions
How many accounts should a small business chart of accounts have?
There is no fixed number, but many SMBs do well with somewhere between 40 and 100 accounts across all types, using dimensions like department or project for further detail rather than adding more accounts. If you are adding an account for every new vendor or initiative, the chart is being asked to do a dimension’s job.
What numbering convention should I use for a chart of accounts?
A common convention assigns number ranges by type - for example 1000s for assets, 2000s for liabilities, 3000s for equity, 4000s for revenue, and 5000s and up for expenses. The specific ranges matter less than picking one convention and applying it consistently so accounts sort and group predictably.
What are dimensions and why do they matter for a chart of accounts?
Dimensions are tags - department, project, location, class - attached to a transaction alongside its GL account. They let you report on "software spend by department" without creating a separate software account for every department, which keeps the core chart of accounts lean while still supporting detailed reporting.
Can I change my chart of accounts after it is already in use?
Yes, but carefully - merging or renaming accounts affects historical reporting, so most teams add new accounts going forward and archive old ones rather than deleting or renumbering. Reviewing the structure annually, as the business changes, is normal and expected rather than a sign something was set up wrong.
