The Synder alternative that also tracks your inventory.
Both sync your sales to QuickBooks or Xero. ConnectBooks is built for ecommerce inventory: it tracks your stock and costs every sale at FIFO with landed cost, so your profit per SKU is right.
Summary
Synder is a broad accounting sync for payment processors, stores and SaaS. ConnectBooks is built for ecommerce sellers, with inventory, FIFO cost of goods and profit by SKU in one platform.
Proof
“We gained back three out of every four hours we used to waste on bookkeeping manually. Now we use that time to up our sales and margins.”
Stack
Synder Sync posts your sales, and Synder Insights is a separate product for analysis. For FIFO and landed cost, you’d add an inventory app. ConnectBooks does all three.
Synder’s site describes Insights as a “stand-alone solution for data analysis”.
One login, one bill, synced to QuickBooks or Xero.
