Hi RuthC1,
It's great to hear that your business is booming and the transactions continue at great levels! QuickBooks Desktop saves your financial information and grows with you. When using a third party app it's best to reach out to them directly for the best course of action, taking into consideration the rate you're business has grown since using their product. I'd be happy to offer other options for you!
Essentially, you can review other apps for QuickBooks Desktop, or you may prefer to create a new company file from your existing one. I recommend consulting with your accountant before making a decision to ensure you're on the right track for your business needs. If you don't have an accountant we can help you locate a ProAdvisor in your local area.
In addition, here's a handy article on how to resolve QuickBooks Desktop performance issues.
If you have any other questions, please feel free to reach back out. We'd be glad to assist!
