# SME Business Dataset (Free Samples — AU, US, UK)

Realistic, relational business datasets generated by simulating retail SMEs day-by-day over 2 financial years. Every transaction flows through double-entry accounting.

**[Browse all datasets and variants →](https://mindweave.tech/datasets)**

**Three variants available:** Australian (ATO/GST), US (IRS/FICA), and UK (HMRC/PAYE/VAT).

## What makes this different

| Feature | AdventureWorks | Northwind | Faker/Mockaroo | **This dataset** |
|---------|---------------|-----------|----------------|-----------------|
| Cross-domain traceability | Partial | No | No | **Full** |
| Double-entry accounting | No | No | No | **Yes** |
| Tax compliance | US-only | None | None | **AU + US + UK** |
| Temporal realism | Static | Static | Random | **Simulated** |
| FK relationships | Good | Basic | None | **44 enforced** |

## Variants

| Directory | Company | Country | Tax Compliance |
|-----------|---------|---------|----------------|
| `data/` | Outback Outdoor Supplies Pty Ltd | AU | ATO PAYG, GST 10%, BAS, Super 11.5% |
| `us/` | Summit Outdoor Gear LLC | US | IRS federal tax, FICA, ~7.5% sales tax |
| `uk/` | Peak District Outdoor Supplies Ltd | UK | HMRC PAYE, NI 10%, VAT 20%, Pension 8% |

Each variant has the same 42-table structure with 44 FK relationships but genuinely different tax rules, salary ranges, payroll frequency, financial year, and locale data.

## Sample contents

~2,800 rows per variant across reference + sampled transaction tables:

- **Company & reference data:** companies, departments, chart of accounts, products, customers
- **Sales:** orders (sampled)
- **Accounting:** journal entries (sampled) — debits always equal credits
- **Payroll, Banking, Tax, Inventory** in the full dataset
