How we work
Four stages, and you know the fee before the first one.
01
Proposal
A fixed fee and a written scope, usually within two working days of the first call.
02
Onboarding
Access, authorities, and a handover from your previous accountant. We do the chasing.
03
The year
Monthly or quarterly work on a schedule you can see, with nothing left to the final month.
04
Filing
Accounts and returns reviewed with you before submission, never after.
