How eBay two-way sync works

Once eBay is connected, PalmFlow keeps your inventory and eBay in step automatically. This page explains exactly what moves, and which direction.

Into PalmFlow

• Listings — your active eBay listings show up as items, so your PalmFlow inventory reflects what's actually live.
• Orders — when something sells, the order pulls in with the details needed to fulfill it, and the matching item is marked sold.
• Fees — eBay's final value fee and other charges are captured on each sale, feeding straight into your profit numbers.

Back out to eBay

• Inventory state — as items sell or end, quantities and status stay consistent on eBay so you're not overselling or showing stale stock.

Why server-side sync beats an extension

PalmFlow talks to eBay through its official API from our servers. A lot of reseller tools lean on a Chrome extension instead. The practical difference:

• Sync runs even when your computer is off.
• A Chrome update or an eBay redesign doesn't break anything.
• There's no extension to install or keep signed in.

Keeping it accurate

• If a sale or listing looks off, open the item — its timeline shows every sync event, so you can see what happened and when.
• Cost basis isn't something eBay knows, so make sure each item has a cost recorded for profit to be correct. See Profit and cost basis.

Selling on other channels

eBay is the only live sync today. For other marketplaces you can log sales manually — the Sell flow includes a platform field, and reports break profit down by platform — so a multi-channel business still gets one accurate P&L while more integrations roll out.

PalmFlow is inventory, eBay sync, and bookkeeping for resellers — in one place.
