SoStocked Review 2026: Is It Worth It for Amazon Inventory?

SoStocked is the most Amazon-specific inventory and forecasting tool most FBA sellers will find. It fits multi-SKU Amazon brands that bleed margin to stockouts, overstock, and storage fees. If you only need a simple low-stock reminder, a cheaper tool does that job.

The honest catch is price and scope. ProfitFlow starts at $97 a month, and the full inventory product is demo-led from $250 a month. SoStocked plans Amazon inventory only, so multichannel brands should look elsewhere. We rate SoStocked 4.5 out of 5.

Quick Verdict

SoStocked earns 4.5 out of 5 because its forecasting follows real Amazon rules, not generic inventory math. You get 12-month demand forecasting, AWD-aware planning, reorder alerts, purchase orders, and ProfitFlow margin tools. The weak spots are an Amazon-only scope, a $250-plus inventory tier, and no public annual pricing.

• Buy if you run several Amazon ASINs and lose money to stockouts, storage fees, or messy reorder timing.
• Skip if you sell across many channels or only need a basic low-stock alert.

The Bouncer: Who Should NOT Buy SoStocked

SoStocked makes sense once Amazon inventory math already hurts. It is a poor fit for single-product sellers, multichannel brands, and anyone who just wants a low-stock email. The $250 inventory tier raises the bar further. Four buyers should look elsewhere before booking a SoStocked demo.

• You sell across many channels. SoStocked plans Amazon inventory only, including Amazon-fulfilled MCF. Brands juggling Shopify, wholesale, and retail need broader forecasting. The Inventory Planner platform covers multi-location and multichannel demand instead.
• You want profit data on a budget. The SoStocked inventory tier starts at $250 a month. Sellers who mainly need per-SKU profit, fees, and reimbursements get more from the Sellerboard dashboard at $19 a month.
• You only need a restock nudge. SoStocked is a planning system, not an alert app. If a simple low-stock reminder is enough, the lighter RestockPro app handles FBA restocks with less setup.
• Your catalog is tiny. One or two SKUs do not need 12-month forecasting models. A spreadsheet or an all-in-one suite like Helium 10 covers that stage for less.

SoStocked at a Glance

SoStocked stands out because it speaks Amazon, not generic inventory. The value sits in Amazon-aware forecasting, fee protection, AWD planning, purchase orders, and profit visibility in one workflow. That suits operators who feel Amazon complexity, not sellers who only want a basic stock count.

• Core job: Amazon demand forecasting and replenishment planning, up to 12 months ahead.
• Fee protection: dashboards for low inventory level fees, overstock fees, and capacity limits.
• Amazon integrations: AWD sync, Capacity Manager, and Amazon-fulfilled MCF tracking.
• Order workflow: purchase orders, reorder alerts, and supplier plus inventory tracking.
• Profit tools: ProfitFlow models COGS, margins, and future Amazon fees per ASIN.
• Pricing: ProfitFlow at $97/mo, ProfitFlow + Inventory from $250/mo.
• Main caution: built for Amazon only, with no public annual pricing.

What Is SoStocked?

SoStocked is Amazon inventory management and forecasting software launched in 2019. Amazon sellers Chelsea Cohen, John Koch, and Dan Fernandez built it to fix their own stockout and overstock pain. Carbon6 acquired it in 2022, and it now sits inside the SPS Commerce seller software lineup.

The simplest way to picture SoStocked is a forecasting engine wrapped in Amazon operating rules. It models how fast each ASIN sells, then turns that into reorder timing, transfer quantities, and fee warnings. You plan the next purchase order and judge whether the product still earns its shelf space.

Who Should Use SoStocked?

SoStocked fits Amazon sellers who have outgrown spreadsheets and feel real money leaking from inventory mistakes. The sweet spot runs several ASINs, ships into FBA, and cares about storage fees, capacity limits, and reorder timing. It rewards operational discipline and punishes casual, low-volume sellers.

• Multi-SKU private label brands that cannot afford to stock out on hero products.
• Seasonal sellers who need forecasting that accounts for spikes and promotions.
• FBA operators managing capacity limits, AWD transfers, and low inventory level fees.
• Margin-focused sellers who want reorder timing tied to profit, not just stock counts.
• Teams that run purchase orders and supplier schedules inside one system.

SoStocked Features

SoStocked is strongest used as a planning system, not a stock counter. The features cluster into four jobs. First is demand forecasting. Second is replenishment and order management. Third is Amazon fee and capacity protection. Fourth is ProfitFlow profit planning.

Amazon Demand Forecasting

SoStocked forecasts demand up to 12 months ahead, factoring seasonality, trends, promotions, and past stockouts. That is a real model, not a reorder reminder. The forecast shifts as sales velocity changes, so hero products keep cover while slow movers avoid overstock.

Operator scenario: Picture a seller heading into Q4 with a product that triples in November. A flat reorder rule would run it dry by mid-month. SoStocked lifts the projected demand curve for that window, so the purchase order covers the spike before it lands.

Expand

• Projects demand up to 12 months out for each ASIN.
• Adjusts for seasonality, promotions, trends, and prior stockouts.
• Flags hero SKUs that need deeper safety stock.

Replenishment and Order Management

SoStocked turns forecasts into reorder timing and purchase orders. It tracks reorder points, min and max levels, supplier lead times, and transfer quantities. Reorder alerts fire before a SKU drops below cover, and purchase orders move from draft to received in one system.

Operator scenario: Say you juggle 40 SKUs across three suppliers with different lead times. Tracking that in a spreadsheet invites a missed reorder every month. SoStocked groups the due orders, suggests quantities from the forecast, and builds the purchase orders for you.

Expand

• Reorder alerts based on forecasted days of supply.
• Min and max restocking controls for each SKU.
• Purchase orders, work orders, and supplier tracking in one place.

Amazon Fee and Capacity Protection

SoStocked plans around Amazon fee and capacity rules, where generic tools go blind. It factors Capacity Limits into restock math and watches the low inventory level fee threshold. Aging stock gets flagged before overstock fees bite. It also integrates with Amazon Warehousing and Distribution (AWD) to sync upstream stock.

Operator scenario: Imagine FBA capacity tightens right as a restock lands. Send too much and overstock fees hit. Send too little and the low inventory level fee hits. SoStocked sizes the transfer to stay inside both limits, so the shipment fits the window.

• Capacity Manager folds Amazon Capacity Limits into restock planning.
• Low inventory and overstock fee dashboards flag costly stock levels.
• AWD integration syncs upstream inventory with FBA replenishment.
• Tracks Amazon-fulfilled MCF orders alongside FBA demand.

ProfitFlow Profit Planning

ProfitFlow is the SoStocked profit layer, priced at $97 a month on its own. It runs the same forecasting engine against projected COGS, margins, and future Amazon fees. The goal is to show which ASINs make money and which quietly lose it. You stop reordering products that no longer earn their cash.

Operator scenario: Say a steady seller looks healthy on revenue but thin on margin after fee creep. Reordering it on autopilot burns cash. ProfitFlow projects the unit economics forward and flags the leak. You cut the order or raise the price before the next PO.

Expand

• Projects COGS, margins, and future Amazon fees per ASIN.
• Flags underperforming products and hidden fee drains.
• Ties replenishment decisions to profitability, not just stock.

SoStocked Pricing

SoStocked pricing splits into two products. ProfitFlow costs $97 a month and opens with a free trial. ProfitFlow + Inventory starts at $250 a month and is sold through a demo, not a self-serve checkout. Annual pricing is not published, so yearly budgeting needs a sales conversation.

• Free trial: ProfitFlow offers a free trial; the inventory tier is demo-led, so you book a call first.
• Annual pricing: not shown publicly, so confirm yearly terms with sales.
• Scaling cost: the inventory product scales with catalog size, so the $250 floor rises for larger catalogs.

Pricing is the main friction in this review. ProfitFlow is easy to start. The inventory product most brands actually want sits behind a demo and a higher floor. The current figures sit on the official SoStocked product page, now under SPS Commerce. The cost makes sense once stockouts and storage fees already cost you more than the subscription.

SoStocked Pros and Cons

SoStocked earns its place on Amazon-specific depth and loses points on price and scope. Judge it as a specialist forecasting system, not a cheap all-rounder. Six clear strengths and six real drawbacks frame the tradeoff. The right call depends on whether Amazon inventory complexity already costs you real money.

Decision Matrix: SoStocked vs Sellerboard vs Inventory Planner

The real choice is rarely SoStocked against one rival. It is SoStocked versus a budget profit tool and a multichannel forecasting platform. Three things decide it. First is whether you sell only on Amazon. Second is your budget. Third is whether you need deep forecasting or just profit visibility.

• Choose SoStocked if: you sell mainly on Amazon and need deep, fee-aware forecasting and reorder planning.
• Choose Sellerboard if: you want per-SKU profit, fees, and reimbursements on a $19-a-month budget.
• Choose Inventory Planner if: you forecast across Shopify, wholesale, and retail, not just Amazon.

SoStocked vs. the Competition

SoStocked competes best against lighter Amazon tools once forecasting gets complex. It looks expensive next to budget profit apps and narrow next to multichannel platforms. Against other Amazon inventory tools, the choice comes down to forecasting depth, fee awareness, and price. The table lines them up.

Each rival wins a different seller. Some sellers want one cheap dashboard for profit and reimbursements. For them, the Sellerboard platform covers profit, inventory, and refunds at $19 a month, without SoStocked’s forecasting depth. Other brands sell well beyond Amazon. The Inventory Planner tool forecasts across stores and warehouses, where SoStocked stays Amazon-only.

The closest head-to-head is SoStocked versus RestockPro. Both plan FBA restocks and build purchase orders. SoStocked wins on forecasting depth and profit modeling. RestockPro counters with a simpler setup at a similar $99 entry. The RestockPro app fits sellers who want restock suggestions without the deeper planning layer.

What Real Users Say

SoStocked has a smaller public review trail than big Amazon suites. It is a niche, premium tool, so star counts on G2 and Capterra stay thin. The signal that exists is positive. Tekpon lists an aggregate 4.3 out of 5, and SoStocked customers point to time saved and fewer stockouts.

What customers praise most:

• Managing order and transfer schedules that used to eat hours of spreadsheet work.
• Forecasting that keeps hero products in stock, since being out of stock costs sales.
• Saved dashboard views for inventory, forecasting, and bookkeeping in a few clicks.

The recurring cautions:

• The inventory tier’s price is the most common hesitation for smaller sellers.
• The depth takes time to learn, so value depends on actually using it.
• Amazon-only scope frustrates brands that later add other channels.

All Day Soiree, an Amazon seller, says SoStocked does the old manual work in "a few clicks." Treat vendor testimonials as a starting point, not proof. Use the free trial to judge fit on your own catalog.

Support, Onboarding, and Free Tools

SoStocked is sold and onboarded like a planning system, not a self-serve app. ProfitFlow starts with a free trial, while the inventory product begins with a demo. Support leans on a deep knowledge base, onboarding help, and best-practice guides that read like an Amazon inventory course.

• Onboarding: a free trial for ProfitFlow and a guided demo for the inventory tier.
• Knowledge base: detailed help docs on days of supply, fees, capacity, and transfers.
• Best-practice guidance: SoStocked recommends holding 35 to 90 days of FBA supply.
• Education: public guides on low inventory level fees, capacity tiering, and overstock.

The Verdict

SoStocked is easy to recommend for the right seller and easy to oversell for the wrong one. Say you run a multi-SKU Amazon brand losing margin to stockouts, storage fees, and reorder mistakes. The depth pays for itself. The price and Amazon-only scope keep this at 4.5 out of 5, not higher.

• Pick SoStocked if Amazon inventory complexity already costs you more than the subscription.
• Skip SoStocked if you sell across channels or only need a simple low-stock alert.
