Let's shortcut to what's wrong with Bqool, before explaining how it works.
I personally spent several hours inside Bqool, looking for ways it was both better and worse than NeuroPrice. What follows are the disadvantages of Bqool. (NeuroPrice also has some downsides too, and I'll get to those...)
#1: Unnecessary number of settings. The number of options in Bqool is absolutely staggering (and I don't think that's a good thing). One of the worse feelings to have when using a repricer is being left to wonder if you missed something, or aren't using it right. Bqool makes tracking all their settings almost impossible. It leaves the user feeling paralyzed trying to comprehend it all.
#2: You have to connect your Amazon account. Minor gripe here, but having to grant Bqool access to my Amazon account is a cumbersome step. I'm not paranoid about them doing anything shady with my account, but I would strongly prefer to avoid this when I'm using any software tool.
#3: Unbelievably confusing settings: In addition to the large number of settings, they are often impossible (to me) to understand. I've been an Amazon seller since 2007, so I should be able to understand basically how your repricer works and what the settings mean. That was impossible for me with much of Bqool.
#4: It forces you to only price against the lowest price offer. This is among my biggest grievances with Bqool (maybe the biggest), and it is a byproduct of the "blindspots" issue I talked about above. Bqool forces sellers to compete with either the Buy Box offer, or the lowest price competitor - and that's it. It is simply impossible to tell Bqool "match my price to the 2nd lowest FBA price" or "price 10% below the 3rd lowest FBA price" or anything related to higher priced offers. This is a HUGE miss for Bqool, dragging prices down unnecessarily.
#5: The FBA blindspot. This significant. The FBA blindspot was explained elsewhere in this article, but to recap: It's a restriction Amazon makes on all software that limits what FBA prices it shares.
In super-specific terms, if there are more than 20 other sellers selling the same item, and the lowest FBA price is above the 20th lowest-priced offer (as often happens), then that FBA price is invisible to your repricer.
Spoiler, but NeuroPrice doesn't have this blindspot. So as an FBA seller, it's hard to accept that a certain percentage of my inventory will not be repriced correctly with Bqool. It's not their fault exactly, it's just a limitation of how they choose to get their data.
#6: You can't reprice by Sales Rank. This one is almost too crazy to believe. For a tool that offers so many unnecessary options, how did they such a huge (and very necessary) one? Bqool has no setting that lets you price your items differently based on their Amazon Sales Rank.
In other words: Do you want to reprice that Book selling 1,000 copies a day differently than one selling once every 2 years? Of course you do. But Bqool doesn't allow it.
I had to back through Bqool multiple times to confirm this since it was so hard to believe. But I never found any mention of Sales Rank anywhere. Huge issue.
#7: You can't reprice by product category. Let's say your inventory includes Toys, Grocery items, and Books. You should want to have separate repricing formulas for each of those. Strangely, Bqool doesn't have a setting for this.
#8: Can't review your prices before committing. It's a little scary to put trust in a repricing tool, and have confidence it's repricing your inventory the way you expect it to. A feature I like to see is the option to see updated prices before I commit to them. Bqool does not allow this.
#9: No Keepa price or sales history charts. Small grievance here, but I would prefer to have access to Keepa charts on the "Manage Listing" page in Keepa. This would let you get the data required to accurately assign a pricing rule, etc. Unfortunately, this is not provided.
#10: No ability to price below Amazon's offer. This is another one where I thought "Surely I'm missing something here..." Someone contact me if I missed something, but I don't think so. Bqool does not have a setting that forces your price to stay below Amazon's price. Again, hard to believe.
#11: Lack of "AI" transparency. Bqool has multiple "AI"-based options, but they offer no explanation as to how their artificial intelligence works. This is concerning, because you are trusting your inventory to a formula that is not revealed. Personally, I would never turn my inventory over to AI or an algorithm without full transparency into how my inventory was being repriced.
#12: Bqool is more expensive. Not a big deal if you're getting extra profit for the price, but in Bqool's case I don't think that's true (unless you're a larger seller). NeuroPrice lets you reprice up to 2,000 SKUs for $27/month, and their cheapest plan is $17/month. Repricing 2,000 SKUs with Bqool costs $50, and their cheapest plan is $25/month. (There are various pricing tiers for each tool depending on your inventory size).
That's my full list of every reason I think Bqool is inferior to NeuroPrice. But what's wrong with NeuroPrice? There's a few things...
