A category generator is a drafting tool — it turns the blank page into a workable first draft. Here's where that draft earns its keep.
1. Setting up books for a new business
The classic use case. You've formed the business, opened the bank account, and now the accounting app asks for a chart of accounts. Generate a numbered starting list for your business type, paste it in, rename a few accounts to match your vocabulary, delete what doesn't apply. An afternoon's work becomes twenty minutes — and you start with a structure instead of improvising one transaction at a time.
2. Freelancers organizing their finances
Solo workers switching from "one big spreadsheet column called expenses" to real categories. The freelancer preset gives you income streams plus the expense categories that matter — software, home office, professional development — without the inventory and payroll accounts you'll never use. See the freelancer guide for the full thinking.
3. Building spreadsheet templates
Bookkeepers and virtual assistants who build trackers for clients need a clean category list per engagement. Generate a numbered set, drop it into the template's dropdown column, and every client starts from the same consistent structure. Consistency across clients is what makes a bookkeeper's life manageable.
4. Teaching bookkeeping
Instructors and course creators use category lists as teaching material: show students the five account types, then have them code sample transactions. The type-prefixed output format exists for exactly this — each row carries its group label, so the structure teaches itself.
5. Migrating to new accounting software
Moving from spreadsheets to an accounting app (or between apps) is the moment to clean house. Generate a fresh, minimal list rather than importing years of accumulated clutter — then map old accounts to new ones deliberately. Migrations done this way produce cleaner reports for years.
6. Side projects and hobby businesses
Small revenue streams deserve real books too — especially when tax time arrives. A twelve-category starter list takes two minutes to generate and saves hours of reconstructing "what was that transfer for" in April.
What it's not for
LedgerLeaf drafts categories; it doesn't do your bookkeeping, doesn't know your tax jurisdiction, and doesn't replace professional advice. Use it for the structure, then bring the judgment — yours, or your accountant's.
