Dueboard is a deadline board for UK bookkeepers and sole practitioners. Import company numbers (CSV or paste) and see every client's accounts deadline and confirmation-statement (CS01) date on one board, plus the estimated Companies House late-accounts penalty in pounds.
Companies House already sends free filing reminders. Dueboard complements those by showing the whole client list and the late-accounts amount at stake before a filing slips. It is not unique versus FastUK, CHWatch, and CoHoWatch.
Late-accounts estimates use GOV.UK private company / LLP bands: £150, £375, £750, and £1,500 (may double if late in two successive years). These are estimates, not legal advice. CS01 dates are shown so you can chase them. Dueboard does not invent an automatic CS01 fine.
Free covers 3 companies. Solo is £12/month for up to 120 companies, with in-app deadline alerts. Optional iCal feed. Data comes from the Companies House public API. Not affiliated with Companies House.
