How it works
From “my Excel file” to “ready for HMRC”
No mystery buttons. Map the figures you already keep, check them, hold evidence, and file only when you are ready.
Sign in or request access
Existing customers sign in. New public account creation is paused while the sandbox programme is completed. Seat plans remain staged for professional access.
Totals linked from your file
Check them before any live HMRC path.
Bring your spreadsheet
Upload supported Excel or CSV. Map the cumulative totals you already maintain — we do not force a full ledger rebuild.
Check before you file
Review figures and warnings. Keep evidence for your records. Trial Mode cannot live-file to HMRC.
Connect HMRC when ready
Authorise when the work is ready. Live filing only when access, authority and security allow it. Production HMRC access is not claimed until HMRC grants it.
Totals linked from your file
Check them before any live HMRC path.
What this is not
Not a full accounting suite
We do not replace bank feeds, invoicing, payroll or inventory tools. If you need those, buy those products. If you need a spreadsheet bridge for MTD Income Tax, you are in the right place.
Registrations are paused — product work continues
QuarterLink is completing its HMRC sandbox programme for direct-taxpayer in-year quarterly bridging. New public accounts are not being created while that work is evidenced.
