Which one should you choose?

Choose SellerGuards if…
  • Your priority is accurate profit on what actually happened — FIFO cost of goods and a real month-by-month P&L.
  • You want reimbursement recovery and a built-in finance module for non-Amazon income, expenses and mileage.
  • You want restock alerts without paying for a full forecasting-and-PO platform — and to start free.
  • You sell on Amazon US and want profit, reimbursements and product research in one place.
Choose SoStocked if…
  • Inventory forecasting is your core pain — long-range demand planning with seasonality and trends.
  • You need purchase-order creation and multi-supplier, multi-warehouse management.
  • You want forward-looking profit forecasting (ProfitFlow) to catch margin drains before they happen.
  • You run a larger operation and have the budget for a dedicated planning platform.

Forecasting and accounting solve different problems, and some sellers run both. If you have to start with one, start with the numbers you can trust — your actual profit. That's what SellerGuards is built for.

Frequently Asked Questions

What is the difference between SellerGuards and SoStocked?

They emphasize different sides of the business. SoStocked is an inventory-forecasting and purchase-order platform — demand forecasting up to 12 months, reorder alerts, multi-supplier and multi-warehouse planning, with its ProfitFlow add-on forecasting sales, fees and costs to flag margin drains. SellerGuards is a profit-accounting tool focused on actuals — true FIFO lot-based cost of goods, a real month-by-month P&L, reimbursement recovery, and a built-in finance module — with restock alerts included. In short: SoStocked leans forward-looking planning; SellerGuards leans accurate profit accounting.

Is SellerGuards cheaper than SoStocked?

Yes, meaningfully. SoStocked's ProfitFlow starts around $97/mo, and ProfitFlow plus full inventory planning starts around $250/mo. SellerGuards starts free and stays a few dollars a month as you grow. The tools aim at different budgets and needs, so compare current pricing on each vendor's page before deciding.

Does SellerGuards forecast inventory and create purchase orders like SoStocked?

Not to the same depth. SoStocked specializes in long-range demand forecasting, reorder planning, purchase-order creation, and multi-supplier/multi-warehouse management. SellerGuards includes inventory tracking and restock alerts so you know when to reorder, but it is not a dedicated forecasting-and-PO platform. If complex, multi-warehouse forecasting is your core need, SoStocked is purpose-built for that.

Does SoStocked give a real P&L and FIFO cost of goods like SellerGuards?

SoStocked's ProfitFlow forecasts profit by factoring fees and product costs at the ASIN level, which is forward-looking. SellerGuards focuses on actual, historical accounting: FIFO cost of goods at the purchase-lot level, a real month-by-month P&L, reimbursement recovery, and a finance module for non-Amazon income and expenses. If you want precise books on what actually happened, that is SellerGuards's focus.

Which marketplaces does each tool support?

SoStocked works across Amazon marketplaces and integrates with Amazon Warehouse Deals (AWD) and Multi-Channel Fulfillment (MCF). SellerGuards currently supports the US marketplace (Amazon.com), with more on the way — once you connect, new marketplaces switch on automatically as they roll out. If you need broad marketplace coverage today, SoStocked has it now.
