GMP Calc is not a calculator that can be easily overwhelmed.  Enter as long and complex a formula as you like and it will provide an answer to the precision of your choice, the default is 10000 significant digits! Optimized for different CPU's, it will detect and automatically use the quickest libraries for your configuration. This applies to 64 bit operating systems only, 32 bit OS's will use slower generic libraries, so 64 bit is recommended.

GMP Calc will run on any Windows version, 32 or 64 bit, with .Net 2.0.

Introducing HighGear

HighGear is a Client/Server software platform that will help your transport company run smoothly and efficiently like never before. From work order to dispatch to billing to payroll, topped off with a wide variety of useful reports, HighGear provides methods of simplifying the management of a transport company, even several transport companies.

Dispatchers will wonder where HG's been hiding, it's never been so simple! HG's drag & drop interface will make it a breeze, including for the less experienced dispatcher.

Fully customizable views and filters to suit the harshest of critics, you are in control of how you want to view and group your data, then save and share those views/filters, as many as you like, to show the data the way you need it, when you need it.

HighGear supports multiple companies under one roof, allowing each to share different legs of a job and handles the complexity of calculating each companies percentage of a work order with the use of PCMiler. The client would receive an invoice from only one company, but internally there would be what we call charge backs. This unique feature of HighGear can really simplify your operation if you have multiple companies.

Need special features? No problem, when necessary we'll do custom programming according to your needs, anything from special payroll codes to accounting practices, using either modules or programmed directly into your customized version of HighGear.
