About Lightning Retail

Tools for online sellers

Lightning Retail builds simple, accurate tools that help online sellers understand their numbers: what they really pay in fees, what to charge, and what they actually keep.

Selling online means juggling marketplace fees, payment fees, shipping, and changing platform rules. Most sellers don't have time to build spreadsheets or decode fee statements. Our tools do that work in minutes, using your own numbers, with clear explanations and cited sources.

What we believe

• Your numbers, your decisions. Our tools show the math. We never promise savings or results.
• Accuracy over hype. Fee data is sourced from official platform pages and dated so you know it's current.
• Simple beats clever. If a tool takes more than a few minutes to use, we haven't finished building it.
