Plan before you sell.
SellerPlanKit helps first-time marketplace sellers understand capital, profit, advertising limits, and the next decision before they spend money.
What we build
Free calculators, practical guides, course research, and software comparisons connected to one product-planning workflow.
Who it is for
People researching Amazon FBA, preparing a first product, comparing training, or deciding which seller tools are actually necessary.
Product direction
From calculators to a complete launch planner
Amazon US is the first vertical. The long-term system will cover startup readiness, product research, pricing, advertising, inventory, cash flow, risk, courses, software, and services.

How recommendations work
The calculator diagnoses a planning problem first. A course, software product, or service can appear only when it is relevant to that problem. Affiliate commission must not determine the recommendation.
Editorial limits
SellerPlanKit does not promise income, identify guaranteed winning products, or present vendor marketing claims as typical outcomes. Unknown information remains unknown until verified.
Independence
SellerPlanKit is an independent website and is not affiliated with Amazon, Walmart, Etsy, eBay, Shopify, or the vendors discussed on the site.
