Adminsoft 4

A flexible yet simple full accounting program. V4 is much better than V3.
It is very useful for single currency SME's, and contains a few extras that other software lacks eg mileage recording.
It has good interfacing with MS Office including Excel (not starter) and also the free version Open Office 3.3.

It now has a payroll module with RTI functionality.

The program can handle an unlimited number of companies, and multi-currency bank accounts within the cashbook section.

It handles User defined invoices so your logo can be included.

The reporting is a little limited, but can be overcome with some Excel usage

The package can handle any number of periods in a year up to 99, so weeks or 4 weeks are possible. If you need to report differently, just re-enter the period and recalculate, and the reporting figure are changed for you. However 12 or 13 are perfectly adequate. Extending an accounting year is also easy.

One of the best features is the ability to edit or delete erroneous transactions.
