The Community tier covers CT600 preparation for one company: the wizard, ledger classification, iXBRL accounts (FRS 102 §1A or FRS 105), iXBRL CT computations, and on-screen validation against the HMRC schema. You can export the resulting CT600 XML and iXBRL accounts. Direct submission to HMRC is not included on Community. Support is via the community forum and GitHub issues — no 1:1 SLA. Free forever, no credit card.

No. Direct filing through the HMRC Transaction Engine is a paid feature, starting at the Standard tier (£99 a year, billed annually). On the Community tier you prepare and export the CT600 XML and iXBRL accounts; submitting them to HMRC requires a tier with direct filing.

Professional (£299 a year) covers up to 5 companies and is built for director groups and sole-practitioner accountants. Practice (£999 a year) is up to 20 companies with multi-user team access and a Slack support channel — built for accountancy practices managing 10+ clients. At 20 clients, Practice works out at roughly £50 per client per year on annual billing. For more than 20 companies, Enterprise gives you unlimited capacity with SSO and a dedicated account manager.

Community → forum + GitHub issues, community-driven. Standard → email support with a 3 business-day SLA. Professional → priority email with a 1 business-day SLA. Practice → priority email plus a dedicated Slack channel. Enterprise → custom SLA + dedicated account manager.

Yes, at any time. Moving from one paid plan to a higher one takes effect as soon as the pro-rated difference for the rest of your year is paid. Downgrades take effect at the end of the year you have already paid for. Your data stays with you across upgrades and downgrades — only feature access changes.

Your data is preserved. If you downgrade from Practice to Standard, for example, only your most recently active company stays editable; the others become read-only until you upgrade again or export them. We never delete customer data on a downgrade — only on an explicit account-deletion request, with a 30-day grace period.

No. Every paid plan is billed annually — Standard £99, Professional £299 and Practice £999 a year — charged when you subscribe and renewing each year until you cancel. Enterprise customers receive custom annual pricing based on volume and contract length.
