It's great to see you taking steps to streamline your accounting process by moving to an online platform, fmkport.
 
Before making the switch, it's important to ensure that all your data in QuickBooks Desktop (QBDT) is up-to-date and accurate. I suggest backing up your desktop data to avoid any losses during the transition.
 
When you're ready, follow the step-by-step process outlined in this article: Move your QuickBooks Desktop file to QuickBooks Online. It also specifies which actions or data you should prepare for a smooth process.
 
After successfully migrating from QuickBooks Desktop (QBDT) to QuickBooks Online Advanced, explore this resource: Learn what to do after you move from QuickBooks Desktop to QuickBooks Online. It offers valuable guidance on the steps to take post-migration, helping you make the most of QuickBooks Online’s features and functionality for your business.
