CSV import company numbers to Companies House deadlines

Bookkeepers already keep company numbers (CRNs) in spreadsheets. CSV import or paste of those numbers is the category escape hatch from re-typing year-ends. FastUK, CHWatch and CoHoWatch also support this kind of import — Dueboard is not the only option. See /compare.

The offer

Import your company numbers. See every accounts and confirmation-statement deadline — and the Companies House late-accounts penalty in pounds — before you get the letter.

The flow

1. Export company numbers from the sheet you already use.
2. Import a CSV (or paste CRNs) into Dueboard.
3. See accounts and confirmation-statement (CS01) dates on one board.
4. See illustrative late-accounts penalty pounds using GOV.UK private/LLP bands (£150 / £375 / £750 / £1,500; may double if late two successive years).

Free for 3 companies. Solo is £12/month for up to 120. Built for UK bookkeepers and sole practitioners with roughly 30–120 clients.

Honesty

• Free Companies House reminders still matter — register on GOV.UK.
• CS01 dates are shown for chase only — not on the automatic accounts £ ladder. We never invent automatic CS01 fines.
• Penalty figures are estimates, not legal advice — GOV.UK late filing penalties.
