We’ve been using Xero and Liquid Accounts pretty much ever since they were released in the UK and they are great and getting better.
Liquid Accounts is very similar to Xero but takes the concept one step further, with extras such as payroll processing, order processing, stock management etc. If you were to compare the two to boring old Sage products Xero is like Line50 or Instant and Liquid is like 200 only much better!
