Building a Customized Computer System can help reduce employee labor by eliminating double entry. When your quotes are in one system, invoices in another, cash receipts and General Ledger in yet another, your employees are wasting their efforts. Most or all of your systems can be programmed with the same software. Even if you need to keep portions of your existing systems, customized systems programmed in Magic can both access and update data in a wide variety of different database platforms.
