IT support for accountants and accountancy firms
Keep client work moving during busy periods
Slow accounting applications and unavailable files put pressure on partners, payroll teams and clients. Your support needs to reflect tax deadlines, busy periods and the systems your practice depends on.
We combine managed IT support, Microsoft 365 and cloud services, and backup and recovery to keep your people working and your client information accessible.
Evidence from Bronsens and Richardsons
CIS helped Bronsens bring IRIS and shared business systems into a private cloud environment, supporting access across its Oxfordshire offices and remote working. Read the Bronsens case study.
At Richardsons Chartered Accountants, CIS coordinated with a software vendor to improve an unreliable legacy system and supported a move towards paperless working. The practice reported five-figure savings in printing costs. Read the Richardsons case study.
These projects show how support can lead to practical improvements in the way a practice works.
