Two ways to work with us

Compare the two models
Full-Time

Full-Time Model

A dedicated accountant, or a team, working exclusively for your practice. They learn your clients, templates and review notes, and they stay with you. Best for steady, recurring work.

Hourly

Hourly Model

Pay for the hours you use. Best for January peaks, catch-up work and cover when someone is on leave.

Questions practices ask before they outsource

What can an accountancy practice outsource?

Most practices outsource bookkeeping, year-end accounts preparation, payroll, and personal and corporation tax return preparation. Some also outsource audit working papers or management accounts. The practice keeps the client relationship, reviews the work, and signs or files it.

Who is responsible for the work?

Your practice stays responsible to your client. We prepare the work to your standards, and your reviewer approves it before anything is filed or sent.

Will my clients know?

Only if you tell them. Your engagement letter should say that you may use subcontractors, and your professional body's guidance on confidentiality applies.

How is outsourcing priced?

Dedicated resources are priced monthly per person, ad hoc work per hour, and defined jobs such as year-end files can be priced per job. We quote once we know your volumes.

How quickly can we start?

Most practices can start within a few weeks of the first call, beginning with a trial batch. We agree the date with you.
