I flip PCs as a hobby. I buy parts and then either resell individual components or build complete rigs and sell those.

For over a year I tracked everything in Google Sheets. It worked until it didn't. I'd find parts in a drawer with no memory of what I paid. I never subtracted eBay's fee from my "profit." I had no idea how much money was tied up in unsold inventory.

So I built Rig Flip to fix my own problem. It does three things: - Inventory, log parts with purchase price, source, photos, storage location. Always know what's in stock. - Builds, group parts into complete rigs. Total cost rolls up from each component. - Profit, record sales with platform-specific fees. See actual profit per sale, not just revenue minus purchase price.

There's a dashboard showing total profit, profit over time, inventory value, and a CSV export for taxes.

Pricing: Free tier (50 parts, no credit card). Pro at $7/mo for unlimited. Lifetime at $99 as a launch price.

The free tier is fully functional. You can try it without creating a paid account. I'd appreciate any feedback on the UX, the data model, or whether this is useful beyond my own workflow.

Happy to answer questions about the tech choices, the PC flipping niche, or the business model.
