QuarterBridge connects your existing spreadsheet — Excel, CSV, Google Sheets, Apple Numbers, LibreOffice — to HMRC in minutes. Works on Windows and Mac. No accounting software. No migration. Just compliance.
Go from spreadsheet to HMRC-compliant in under five minutes. No accounting jargon, no software migration.
Drag and drop whatever you use — Excel, Google Sheets, CSV, Numbers, LibreOffice. We read them all. Your file is parsed locally in your browser for privacy.
We auto-detect your income and expense columns and suggest HMRC categories in plain English. Adjust anything with dropdowns. Your mapping is saved — you never redo this step.
Review your totals, confirm they're correct, and hit submit. We format everything to HMRC's exact specification and transmit it securely. You get a confirmation with your reference number.
No. HMRC explicitly allows bridging software — a lightweight digital link that connects your existing spreadsheet directly to their systems. You don't need to learn accounting software, migrate your records, or pay £30+/month for features you'll never use.
