Accountants for professional services in London

Consultancies, law firms, recruiters and advisors live and die by billable time and cashflow timing. We tailor cloud bookkeeping to how you bill and work — so you can invoice promptly, track work in progress, and plan ahead with confidence.

Challenges we understand

The realities of billing for your time

We've worked with professional services firms, so the pressures around time and cashflow are familiar to us.

Time billing

Turning recorded time into accurate, timely invoices your clients trust.

Work in progress

Unbilled work that's hard to value and easy to lose track of.

Cashflow timing

The gap between doing the work and getting paid that squeezes cashflow.

Late invoicing

Busy periods where billing slips and revenue is left on the table.

Associates & subcontractors

Variable people costs that need matching to the engagements they serve.

VAT & disbursements

Getting VAT and recharged expenses right across multiple clients.

FAQs

Professional services questions

Can you track billable time and work in progress?
Yes. We set up your books and time tools so recorded time and unbilled work in progress are visible, making it easy to see what's ready to invoice and what's still outstanding — so revenue doesn't slip through the cracks.
Can you help us invoice more promptly?
We streamline the billing process so invoices go out on time, every time. Prompt, accurate invoicing is one of the simplest ways to improve cashflow, and we make it routine rather than a scramble at month-end.
How do you handle associates and disbursements?
We capture and code associate or subcontractor costs and client disbursements to the right engagements, and make sure VAT and recharges are treated correctly — so your margins and your invoices both stand up to scrutiny.
How do we get started?
Book a free consultation. We'll learn how your firm bills and works, set up or tidy your Xero, and take the bookkeeping off your plate — with clear, time-aware reporting from there on.
