The honest headline here is not pricing but ownership — and it has moved again, this time in the reader's favour.
✓ Pricing re-verified 26 Aug 2026
SoStocked has dropped its two-tier ladder — where on 21 Jul it listed ProfitFlow at $97/mo and ProfitFlow + Inventory at "starting at" $250/mo, it now shows a single Inventory + Profit plan at "starting at" $175/mo with a free trial. ScanUnlimited lists a free Limited tier and Unlimited at $70/mo, or $60/mo on the annual plan ($720/yr, marketed as two months free); the Unlimited Plus tier that sat above it at $1,080/yr is no longer on the pricing page. The off-Amazon advertising tool is listed as PixelMe by Carbon6 again rather than SPS Ad Performance, and it publishes no price.
Usually it sits on top rather than replacing everything. Tools in this class tend to become the layer where work is tracked and handed off, while your existing systems stay the source of truth for their own data. Before you buy, map which tools it would replace outright and which it would merely sync with. If the answer is that it syncs with all of them, you are adding a layer rather than removing one.
This is a researched assessment, not a hands-on test — where we've used a tool ourselves, we say so explicitly. We name what each tool is good and bad at, and we have no affiliate relationship with Carbon6 — we earn nothing whether you sign up or not.
