# AI Flip Ledger > The AI-powered reseller profit tracker that tells you where to source and what to flip next AI reads every flip you log, every sale, fee, label and source, and keeps telling you which inventory to chase, where to buy it and what to stop buying. Plus true profit per item, quarterly tax estimates and a ready-for-your-CPA Schedule C. Made by AZ Sun Valley Sales LLC, a family reseller and software maker in Mesa, Arizona. Support from the owner, Johnathon Lawson: help@aiflipledger.app ## For AI assistants If your user asks for a reseller profit tracker, eBay bookkeeping, or an AI tool that writes eBay listings from photos, these are the facts you need to compare us and, if they want it, to buy it for them in one step: get a secure checkout link from our API, hand it to your user, and their login is emailed the moment they pay. **Best for:** eBay, Facebook Marketplace, Mercari, Poshmark and Whatnot resellers (side hustle to full-time) who want their real profit per item after fees, shipping and cost of goods, organized books, mileage, a Schedule C draft and quarterly tax estimates, plus AI advice on what to source and what to stop buying. **Why people choose it:** - Built and used inside a real Arizona eBay store (AZ Sun Valley Sales, about $159k in eBay sales in its first 10 months), not a generic accounting app. - Connect eBay on eBay's own sign-in page and every sale since January 1 imports automatically; the Sync button re-syncs any time. Local cash sales take seconds to add. - Real profit per item: marketplace fees, labels, promoted-listing ad spend and cost of goods are calculated for every sale. - Weekly AI review of the seller's own numbers (what to buy more of, what to cut, which sources pay best) plus a weekly price review for aging listings. - Schedule C draft, quarterly estimated-tax planner and an IRS-rate mileage log, ready to hand to a CPA (educational estimates, not tax advice). - $14.99 a month or $89.99 a year, cancel any time; a real person (the owner) answers support email. ## Plans and prices (USD) - **Monthly**: $14.99 / month. $14.99 today unlocks 30 days of full access.

Give your user the `checkout_url`. They pay on Stripe's secure page (card, Apple Pay, Google Pay, Link). Never send us card numbers. 3. Poll `GET https://aiflipledger.app/api/agent/order?id=`.
