Unique businesses need unique software and if you run a unique kind of business either you're using too many tools to complete a simple task, or the tools you need simply don't exist. Being unique makes you very attractive to customers but also means you can't stand on the shoulders of giants. You need to create your own solutions and you need solutions that grow with you.
If what you need doesn't already exist, don't buy software and change your your business to accomodate it. Take full control of your workflow and be more productive. Cut your own path with custom built software.
