Pricing Model
Difference
PaidSoStocked's core plan, Inventory + Profit, starts at $175 per month, with the final price scaling based on a seller's monthly order volume; the plan combines profit strategy tools (ProfitFlow) with full inventory forecasting in a single subscription. Carbon6 also offers discounted introductory terms for new customers, such as a 3-month plan around $474 USD (roughly $158/month) for accounts with up to 1,000 orders/month, along with longer-term contract options. Every plan includes free data migration from a seller's existing system (a $199 value), 1-on-1 onboarding, email and chat support, and coverage across all Amazon marketplaces. A free trial is available for sellers to evaluate the platform before committing, though there is no permanent free tier. Sellers with higher order volumes or more complex multi-warehouse needs should expect pricing to scale upward accordingly; exact figures for larger catalogs require contacting SoStocked's sales team.
CustomSignifyd uses fully custom, quote-based pricing with no published flat rates. Costs are typically structured around a merchant's order volume, average order value, and risk profile, since Signifyd backs every approved order with a financial guarantee and prices accordingly. On the Shopify App Store, the Signifyd app itself is free to install, with usage-based fees billed separately by Signifyd outside of the Shopify invoice. Prospective customers need to request a demo or quote directly through Signifyd's website to get pricing tailored to their business.

SoStocked Pros & Cons

Pros

  • Fully customizable forecasting variables give sellers real control instead of a black-box algorithm
  • Built by experienced Amazon sellers specifically to solve real FBA stockout and overstock pain points
  • ProfitFlow extends the platform beyond inventory into proactive, ASIN-level profit protection
  • Free data migration and 1-on-1 onboarding lower the friction of switching from spreadsheets
  • Backed by Carbon6 and SPS Commerce, giving the product stability and a broader ecosystem of seller tools

Cons

  • No free tier; only a free trial is offered before pricing kicks in at $175/month for the base plan
  • Steeper starting price than lighter-weight profit-tracking tools, better suited to sellers who need deep forecasting rather than basic P&L
  • Built specifically for Amazon sellers, with less mature support for non-Amazon or purely Shopify-native inventory workflows
  • Pricing scales with order volume, so costs rise as a catalog grows, requiring budget planning for scaling sellers

Signifyd Pros & Cons

Pros

  • 100% financial guarantee on approved orders removes fraud liability entirely from the merchant
  • Backed by a massive Commerce Network of transaction data spanning thousands of merchants for stronger decisioning
  • Covers the full order lifecycle, from checkout fraud through chargebacks to returns abuse
  • Ranked the #1 payment security and fraud prevention solution for five consecutive years by Digital Commerce 360
  • Proven at enterprise scale with customers like Samsung, Walmart, and eBay
  • Broad, mature integrations across major ecommerce platforms including Shopify, Magento, and Salesforce Commerce Cloud

Cons

  • Pricing is entirely custom with no public rates, requiring a sales conversation to get any estimate
  • Best suited to established ecommerce businesses with real transaction volume, so very small merchants may find it more than they need
  • Financial guarantee model means fees are tied to your risk profile and order volume, making costs harder to predict upfront
  • Recent user feedback flags billing changes and fee structure adjustments that some long-time customers found confusing
  • Full value depends on proper integration and configuration across checkout, fulfillment, and returns workflows
