Hi Nick,
I'm developing our beta version of The Prosperous Shop - an app that not only gives you weekly/monthly reporting, but reads your sales data and gives a health check across your categories of sales performance in relation to stock/orders. We give a list of actions to take every week that will optimise your profits, prompt timely re-buys and flag any pricing or trading issues that can be improved. It works across e-comm as well as brick and mortar sites. I have some screen shots I can send you.
Nick, since you obviously care about moving your business forward, I wonder whether you'd be happy to send me a quick email and let me know any other features that we could include for the Shopify community.
If you'd like to , join our cohort of beta customers and get all of the benefits mentioned for free. All we ask is that you click the like or don't like button as you use our app to help us perfect the retailers experience. I'm at karen@theprosperousshop.com. Be great to hear fom you!
