Actually they are very different. we use both. HP has the main advantage of real time data pulling showing you in real time what ASIN was sold and also if there is a promo or not. To be honest the profit calculator on HP is not always accurate. Is only to get an idea.
MBS has it’s own advantages meaning that you may analyze each child/parent session/conversion/etc so depending on what you analise.. you need both.
as you also need PPCSCOPE (paid version if posible) for analising STReports and many other PPC stuff :)))

I tried Hello Profit and found it to be inaccurate with my data it was pulling (duplicates and missing ASINs). Went back and forth with their support a few times before finally giving up. Prob would’ve stuck with it if data pulled properly.
I tried Cash Cow Pro too and likely it was coincidental but my sales plummeted after installing, then jumped back into position as soon as I uninstalled. It’s the only change to my account in that 24 hr period I can attribute to the unusual sales fluctuation. Have since spoken with a couple SS reps who claim some 3rd party programs can cause those type of issues.

Take a look at https://beanmetrics.com/

I believe it might be a product that will work for you.

We are launching in beta very soon.

And it is free for the first 6 months.(only 49 spots left at the time of this post)

What exactly would you be looking for as far as improvements on profit calculation? The kind of details I need, for example, would be:

• Sales by organic vs. PPC
• Cash flow adjustment due to returned items
• Costs clearly detailed, such as ACoS, FBA storage fees, Other FBA, taxes, CoGS etc.

Besides HelloProfit there’s also Sellics, Cash Cow Pro and Fetcher (from JungleScout)…

I think the inaccuracy in data pulled by any of the SaaS I mentioned above is due to where they put those numbers that they’re pulling from SC… any good bookkeeper knows that bookkeeping is actually quite a creative job! Showing a profit is mainly based upon when certain things are written off, rounding some numbers up or down, etc…

I’d be interested in seeing a blank version of your Excel profit calculation sheets, just to see what kind of numbers you’re looking at, and where you’re putting them and over what period of time. — If you’d be so kind as to share 🙂

Use the sales & profit tool on Sellics; it shows your exact profit margins after Amazon fees, FBA fees, PPC, etc are taken out. Useful to keen an eye on how much money you’re actually making, and based on that number, figure out if you can afford to boost PPC campaigns for low performing products as needed.
