Some avid users of Fusionmetrics have pointed out that the 30-month earnings figure is always showing some deviation from the one shown in the Shopify Partners dashboard. Thankfully, one of our users went even so far to give me access to their Partners Dashboard to get to the bottom of the issue. Ultimately the problem turned out to be due to the timezone of the Partners Dashboard being different from Fusionmetrics. We has been using UTC for defining the start end end of a day in the 30 day period. To get the same earnings figures as in the Dashboard, we now need to know the timezone you want to use for accounting i.e. the timezone you usually view the Partner Dashboard in.
