Our mission
Property and self-employment are messy. Tenancies change, deadlines slip, bank lines rarely match memory. We build for that, not a tidy demo that breaks down in April.
How we build
Design principles
What we use to decide what ships. No feature for feature's sake.
Clarity over cleverness
Plain language, visible status and predictable layouts. You should see what needs attention without decoding jargon.
Quarterly by design
MTD for Income Tax runs on quarters, not a year-end panic. Periods and review are built in from the start, not pasted onto a generic ledger.
Operations and tax together
Properties, tenancies, rent and finance sit next to income and expenses. Totals should trace back to contracts and bank movement, not scattered spreadsheets.
Records that stack up
Income and expenses organised the way UK property and trade filings expect. Less rework when you file or share exports.
Mobile-first, performance-minded
Check compliance, log expenses and review a quarter from your phone. Fast pages, touch-friendly controls, no marketing bloat inside the app.
Honest about compliance
We are not HMRC. We point you to GOV.UK for mandation and filing rules. The software supports your process; it does not replace professional advice.
