# ConnectBooks > ConnectBooks is ecommerce accounting and bookkeeping software that syncs Amazon, Shopify, Walmart, TikTok Shop, and eBay sales, fees, refunds, and settlement data into QuickBooks Online, QuickBooks Desktop, or Xero. It calculates per-unit (FIFO) cost of goods sold, tracks inventory across locations, reconciles marketplace payouts to the penny, and produces SKU-level and per-channel profit and loss for multi-marketplace sellers. ConnectBooks serves ecommerce sellers, bookkeepers, and accounting firms that manage multi-channel inventory and accounting. The core promise is accuracy: every marketplace transaction maps cleanly into QuickBooks or Xero, summarized or line-by-item, so sellers can trust their books and see true profitability by product and by channel. ## Product - [ConnectBooks home](https://www.connectbooks.com): Overview of ConnectBooks ecommerce accounting software and how it automates the marketplace-to-QuickBooks/Xero workflow. - [Pricing](https://www.connectbooks.com/pricing): Plans and pricing.
