Features

Everything in one platform

The compliance engine that powers your firm — and the client app that puts it in their pocket.

Live from HMRC

  • Corporation Tax

    Balances and payment dates pulled from the HMRC agent portal and Companies House.

  • PAYE & NIC

    Outstanding balances, overdue amounts and unallocated credits, surfaced per client.

  • VAT (MTD)

    Obligations and liabilities via the Making Tax Digital API.

  • Self Assessment

    Liabilities and filing deadlines once your MTD credentials are live.

For your clients

  • Firm-branded app

    A simple iOS & Android tax-reminder app carrying your firm's identity.

  • Smart deadlines

    Clients pick their taxes; the app generates the right dates automatically.

  • Reminders they choose

    30 / 15 / 7 / 1 day — or all of them. Gentle nudges, fewer chasing calls.

  • Paid status, end to end

    What you mark in the portal flows straight to the client's app.

Run your firm

  • Karbon sync

    Your client list and work items stay in step with Karbon.

  • Team & roles

    Invite colleagues with the right access; isolate every firm's data.

  • CSV import & invites

    Bulk-load clients and invite them to the app by email or code.

  • Billing by client count

    Transparent tiers that scale as you grow.

Secure by design

  • Two-factor auth

    TOTP MFA, enforced for staff handling client data.

  • Per-firm isolation

    Strict scoping so firms only ever see their own clients.

  • Full audit trail

    Every access to client data is logged.

  • Encrypted credentials

    HMRC tokens and gateway secrets stored AES-256-GCM encrypted.
