SoStocked review (2026): inventory forecasting that prevents stockouts
When you manage 50+ SKUs with different suppliers and lead times, tracking reorder dates in a spreadsheet becomes error-prone, and a single stockout can wipe out weeks of organic ranking. SoStocked (a Carbon6 tool) computes a per-SKU reorder date and plans FBA shipments around Amazon's storage limits, which is exactly where it earns its keep. Jump to pricing, who should buy, or the bottom line.
- What it is: an inventory forecasting tool (a Carbon6 product) that computes a per-SKU reorder date automatically and plans IPI-aware FBA shipments around Amazon's storage limits.
- Best for: private-label sellers managing 50+ SKUs across multiple suppliers and lead times who keep losing time and rank to reorder spreadsheets.
- Pricing: Starter about $49/mo (500 SKUs), Professional about $99/mo (2,000 SKUs), Enterprise about $199/mo (unlimited). Annual billing saves 15-20%.
- Skip it if: you manage under about 50 SKUs (manual tracking is fine) or sell wholesale or arbitrage, where the inventory model differs.
The core strength: a reorder date you can trust
SoStocked forecasts demand per SKU, then layers in supplier lead time, production time, and shipping time to compute the single number that prevents stockouts: the latest date you can place a purchase order without running out. Across 50+ SKUs with different suppliers, that calculation is exactly what a spreadsheet gets wrong, and a stockout does not just lose sales, it sheds the organic ranking you spent months building. SoStocked also plans FBA shipments around Amazon's storage and IPI limits, so you send the right quantities at the right time. It is a narrow tool that does one high-stakes job well.
Pricing
| Plan | Monthly | SKUs | What you get |
|---|---|---|---|
| Starter | ~$49/mo | 500 | Basic forecasting, reorder alerts, 1 marketplace |
| Professional | ~$99/mo | 2,000 | Advanced + seasonal forecasting, multi-marketplace |
| Enterprise | ~$199/mo | Unlimited | All features, API access, priority support, custom reporting |
Annual billing saves 15-20%, and Carbon6 occasionally bundles SoStocked with its PPC and analytics tools at a discount, worth checking if you use more of the suite.
Who should and should not use SoStocked
Strengths
- Trustworthy per-SKU reorder dates
- IPI-aware FBA shipment planning
- Seasonal forecasting on higher tiers
- Multi-marketplace, part of the Carbon6 suite
Weaknesses
- Real added cost ($49-199/mo)
- Overkill below ~50 SKUs
- Built for private label, not wholesale/arbitrage
- Does not track profit (pair with Sellerboard)
Bottom line: should you use SoStocked in 2026?
If you run private label with 50+ SKUs across several suppliers and you have ever lost ranking to a stockout, yes, SoStocked earns its cost the first time it prevents one, and its reorder-date automation plus IPI-aware shipment planning replaces the fragile spreadsheet most sellers limp along on. Below ~50 SKUs, manual tracking is fine and the $49-199/month is hard to justify. Pair it with Sellerboard for profit and a research tool like Helium 10; the three cover different jobs. The 4.0 reflects a focused tool that does its one job well for the catalog it targets.
