The accounting workspace
Keep the books for a company that doesn't exist.
11 fictional companies, each with its own documents, chart of accounts and opening balances. You read the paperwork, post to a real ledger, reconcile, adjust and close — and every figure on the statements comes from your entries, so a mistake in week one shows up at month end.
- Documents and bank statements
- Invoices, remittances, payroll, contracts, count sheets — read them as an accountant would.
- A real ledger
- Post entries, reverse mistakes, reconcile the bank. Posted entries can't be edited, only corrected.
- Statements from your work
- Trial balance, income statement, financial position and cash flows built from your own entries.
- Close and lock
- Adjust, close and lock each period; later months start from the balances you left.

The method
Reading is the smallest part of every lesson.
Accounting is learned the way it is practised: by recording transactions and seeing what they do to the numbers.
- 01
Understand
A short explanation of the idea, in plain language, with the rule stated precisely.
- 02
Observe
A worked example or a simulator you can change and watch respond.
- 03
Practise
Graded exercises with hints: journal entries, worksheets, classifications, calculations.
- 04
Apply
A business scenario at the end of every lesson that needs judgement, not just the rule.
- 05
Master
Mastery counts only when you've earned it — visiting a page isn't progress.
Feedback that teaches
A balanced entry can still be wrong. We tell you how.
Entries are graded on their substance — which accounts change and by how much — so line order doesn't matter, valid alternatives are accepted, and a wrong account is caught even when debits equal credits.
“Incorrect. Try again.”
“Your entry balances, but you recorded an immediate expense instead of a prepaid asset. The payment covers future periods, so the cost becomes an expense as the cover is used.”
Simulators
26 working models of accounting. All free.
Change a rate, a date or a quantity and watch the schedule, the entries and the statements respond. Every figure comes from the same engine that grades your exercises.
