Frequently Asked Questions

What is the difference between SellerGuards and InventoryLab?

Both track Amazon profit and cost of goods, and both currently focus on the US marketplace, but their centers of gravity differ. InventoryLab is an all-in-one FBA operations tool best known for its listing and shipment workflow — a guided replacement for Seller Central — with Scoutify mobile sourcing and a built-in profit-and-loss view. SellerGuards is a dedicated profit-accounting tool: true FIFO lot-based cost of goods, a real month-by-month P&L, reimbursement recovery, product research, and a finance module for non-Amazon income and expenses. If listing and shipping operations are central to your day, InventoryLab is built around that; if profit accuracy is the priority, that's SellerGuards's focus.

Is SellerGuards cheaper than InventoryLab?

Generally yes. InventoryLab is bundled in Seller 365, with plans commonly starting around $69/mo and rising to $129/mo and $199/mo for teams and Pro. SellerGuards starts free and stays a few dollars a month as you grow. Compare current pricing on each vendor's page, since plans change over time.

Does SellerGuards handle listing and shipments like InventoryLab?

No. A guided listing-and-shipment workflow that replaces Seller Central — MSKU generation, inbound plans, box labels — is one of InventoryLab's flagship features, along with the Scoutify sourcing app. SellerGuards does not run your shipment workflow; it focuses on profit accounting, reimbursements and product research. If you want listing and shipping operations in the same tool, InventoryLab is purpose-built for that.

Do both tools track profit and cost of goods with FIFO?

Both provide profit tracking and cost of goods, and both reconcile Amazon fees and settlements. SellerGuards applies FIFO at the purchase-lot level, so each unit's COGS reflects the exact price you paid for that specific batch, and margins update automatically as your buy price changes across lots, plus a finance module for non-Amazon income and expenses. If lot-level FIFO precision and whole-business books are your priority, that is where SellerGuards focuses.

Which marketplaces does each tool support?

Both currently focus on the US marketplace (Amazon.com), so marketplace coverage is roughly even today. SellerGuards has more marketplaces on the way — once you connect, new ones switch on automatically as they roll out. Confirm current coverage on each vendor's page before deciding.
