Property compliance software

Landlord compliance

The Renters’ Rights Act 2025 changed what landlords in England have to prove, and councils can now issue civil penalties of up to £40,000 without a warning first. Kept tracks the key statutory deadlines, holds your certificates, chases you before anything expires, and produces a dated audit pack of what you have done. It covers England today, with Wales coming soon. It is not legal advice.

Tournament software

Tournament software

Most tournaments still run on a spreadsheet, a whiteboard and one very busy organiser. Trophy works out a plan that fits the teams, pitches and hours you have, lets every player join with a single code, and keeps the live table accurate: one side sends a score, the other confirms it, and if they disagree both versions stay visible until the organiser decides.

  • No app, account or password needed to join
  • Football and padel today, more sports on the way
  • Live tables on every phone and the clubhouse TV
  • A set-up that fitsTell Trophy how many teams, pitches and hours you have, and it gives you a workable plan before the invite goes out.
  • One code for everyonePlayers tap a link or type the code and score from their own phone, straight from the browser.
  • Scores both sides agree onOne side sends a result and the other confirms it. The table only moves on confirmed scores, so nobody argues with it.
  • Clubhouse TV and public resultsOne public link shows the table, what is live and what is next, on a phone, a laptop or the screen in the bar.

Also on the day

  • Scoped helper roles

Email signature software

Email signature management

Email signatures usually live in everyone’s own mail app, each slightly out of date. Signed lets you design a signature once, fills in each person’s details and puts the right one on every email. It works with any email provider and connects directly to Microsoft 365 for directory sync and the Outlook add-in. Google Workspace directory sync is coming soon. When someone changes role or a campaign ends, you change it in one place.

  • Works with any email provider
  • Microsoft 365 sync today, Google Workspace sync coming soon

  • Outlook add-inYour Microsoft 365 admin deploys the add-in once, and the right signature appears as people write in Outlook on the web, Windows and Mac.
