Pricing
Specialist VAT tooling, priced to match
Two clear plans. One for accountancy practices and bookkeepers. One for businesses and charities buying for themselves. No setup fees, no per-user charges, cancel anytime.
For practices and bookkeepers
Per-organisation pricing for accountancy practices and bookkeepers managing client books across Xero, QBO, Sage, and FreeAgent.
For businesses and charities
For organisations buying OneSixth for their own books — direct businesses, charities, and groups managing partial exemption, TOMS, or margin schemes in-house.
Practice Plan
Pay per client organisation connected. Unlimited users, all VAT schemes included, full audit trail, MTD compliant.
5–19 organisations
Established practices managing partial exemption across multiple clients.
50+ organisations
Larger practices and networks. We'll tailor a plan around your firm's structure.
All Practice Plan tiers include: unlimited users · all VAT schemes (PE, TOMS, margin, future) · journal posting back to Xero / QBO / Sage / FreeAgent · full audit trail · attached working papers · MTD compliant · UK support.
First organisation free for 90 days. Connect a single client, run one period's calculation, see the journal posted back — then decide.
25% off for registered charities
We discount both plans by 25% for UK registered charities and Community Amateur Sports Clubs. Verifiable at signup via the Charity Commission for England and Wales, OSCR (Scotland), the Charity Commission for Northern Ireland, or the HMRC CASC register. The discount applies to the underlying tier price and stacks with annual billing.
