Hopefully some of the forum's users will find this link useful:
On this site you will find information about a job costing an operations management software package called ProQuin Enterprise.
It uses a simple approach to the problem of managing the day to day operations of service based businesses and is an ideal tool to get some structure into a growing business.
It allows you to process more with less (staff or numbers of hours) and as the business grows makes it so much easier to delegate work out without losing sight of the detail.
If you think it might be of use, you can get a demo over the internet in about 30 or 40 minutes and download a no obligation 30 day trial afterwards.
It will cost nothing to take a look at this, but if it is right for you it might save you thousands in the long term.
