I'm a chartered accountant specialising in small businesses, for bookkeeping services like VAT & Payroll I use [www.detangledadmin.com] They do bespoke packages for each client but have a guideline of prices on their website
Second recommendation for Alex at Savvy Accounting.
Alex is fantastic. Clear, honest, thorough advice and reporting, and very proactive at all key points in the year.
My business wouldn't run as smoothly without her.
