Getting Started

Getting started with OneSixth

Connect your first accounting platform, add a firm, and run your first calculation.

  1. Sign up at /login and create your firm.
  2. From the Dashboard, click Connect organisation and pick your accounting platform (Xero, QuickBooks, Sage, or FreeAgent).
  3. Authorise access. We only read the data needed for the schemes you enable.
  4. Pick a scheme — TOMS, Motor Trade, Global Accounting, Horses & Ponies, General Goods, or Partial Exemption — and run setup.
  5. 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.
