I see this is your first post, so I'd like to welcome you to the Community.
That's a good question! Being able to input a custom date to view your sales statistics in the QBO Dashboard is a great enhancement we could add.
While this option is currently unavailable, I would like to put this forward to our developers and encourage you to send them your product suggestion. Doing this helps them identify what needs to be added and what features should be released to provide you the best experience with our product. Please follow these steps to send your request:
Can I view the sales graph for all sales over the past 5 years instead of just the past 12 months. How can I do that?
They are investing in new features like giving you loans and live bookeeping rather than giving you insight into how your business has evolved over the years. Why? Because it costs processor time to calculate which raises hosting costs while the other two are revenue streams back to Inuit. That is why the feature exists on desktop, it's your computers processing time. The Last 12 months is unacceptable and they know this. Use the new found monthly recurring revenue stream of charging monthly for QBO rather than the once every 3 year upgrade you get with desktop and add features people want or someone else will. I'm hopeful someone with a startup mentality will eventually be promoted there and make change happen.
