Getting Started
Getting started with OneSixth
Connect your first accounting platform, add a firm, and run your first calculation.
- Sign up at /login and create your firm.
- From the Dashboard, click Connect organisation and pick your accounting platform (Xero, QuickBooks, Sage, or FreeAgent).
- Authorise access. We only read the data needed for the schemes you enable.
- Pick a scheme — TOMS, Motor Trade, Global Accounting, Horses & Ponies, General Goods, or Partial Exemption — and run setup.
- Pull transactions for your current VAT period and review the calculation.
Two ways to work
- Practices manage many client organisations from one login. The Accountant portfolio gives a cross-client view with overdue-period alerts.
- Businesses manage their own books — usually a single organisation, or a small group of related entities.
Try before you connect real data
If your firm has beta access, the Training sandbox lets you practise any scheme against realistic dummy data — nothing is posted to a real accounting platform.
If you get stuck on any step, write to help@onesixth.app.
