This is a simple tutorial based on my experience when customizing FrontAccounting. In some cases we may need to have different sales price for the same item but different customer. For the example, we want to sell Item 1 to Customer A with price 500, but for the same item we want to sell to Customer B with price 550. It's true we can edit that price manually when creating the Sales Order. But, it will be more efficient if we can do that automatically based to the data we had.

For Slackware users, installing package by compiling from source using slackbuild script is preferred than installing from binary packages. We can find a lot of slackbuild script at Slackbuilds.org so we can easily search, download, compile, and install new application in our Slackware system. Some applications can be installed and run without need to install its dependencies, but some of them can have one or more dependencies.
