Too much work
Your firm has more bookkeeping than your team can get through.
Hard to hire
Local bookkeepers are expensive and slow to find.
Capped growth
You want more clients, not more payroll.
Months behind
Clients' books are piling up and nobody has time to catch them up.
Who we help
Built for firms that are busy, growing, and out of hours in the day.
We work alongside accounting and bookkeeping practices that need reliable hands on the routine work, not another vendor to manage.
Small and medium accounting practices
Standalone bookkeeping firms
Payroll bureaus
Xero-focused and QuickBooks-focused firms

We don't sign off on accounts
We don't give tax opinions
We don't act as auditors
We don't replace your partners
Why firms choose SPIN
A back office that feels like yours.
Real accounting experience
Our team has hands-on bookkeeping experience, not just data entry training. They know what "right" looks like.
Capacity that flexes
Scale support up during busy season and back down when things ease off, with no fixed headcount to carry.
Faster turnaround
Streamlined workflows and modern tools mean backlogs get cleared in weeks, not quarters.
More affordable than hiring
A fraction of the cost of recruiting, training and retaining local bookkeeping staff.
Same working hours
European time zone overlap means quick turnarounds and easy calls, with no overnight delays.
A long-term partner
We learn your clients, your style, and your software once, then quietly become part of your team.

From first call to cleared backlog.
No long onboarding, no lengthy contracts to evaluate before you see any work done.

Common questions
Before you book a call.
No. We work behind the scenes as an extension of your team. All work is delivered under your firm's name, with no mention of SPIN to your clients.
We work with firms of all sizes, from a single client file that needs catching up to ongoing support across your whole portfolio. There's no minimum commitment to get started.
We work inside your existing software using access you control and can revoke at any time. We sign confidentiality agreements before any client data is shared.
We prepare VAT data, run checks, and put together supporting schedules. Final review and submission always stays with your firm's accountant.
Most engagements start within one to two weeks of our discovery call, once access and scope are agreed.
