Can you recommend a bookkeeping service for tracking COGS across multiple ecommerce sales channels?

Yes — for ecommerce businesses selling across multiple channels, you’ll want a bookkeeping service that can handle:

• Inventory and COGS tracking
• Multi-channel sales reconciliation (Amazon, Shopify, Etsy, Walmart, eBay, etc.)
• Payment processor matching (Stripe, PayPal, Shopify Payments)
• Sales tax support
• Month-end close and financial reporting

Best setup for accurate COGS

If your priority is reliable COGS across multiple channels, the strongest combination is usually:

• QuickBooks Online or Xero
• A connector like A2X, Link My Books, or Synder
• A bookkeeping service that understands ecommerce inventory accounting

This setup helps separate:

• gross sales
• refunds/returns
• marketplace fees
• shipping income/expenses
• COGS
• inventory changes

My recommendation

If you’re serious about accurate COGS across several channels, I’d recommend looking for:

1. An ecommerce-specialized bookkeeping firm
2. Experience with Amazon + Shopify + Etsy/Walmart/etc.
3. Integration with A2X or Link My Books
4. A monthly close process that includes inventory reconciliation

If you want, I can also recommend:

• the best service based on your sales channels
• a low-cost vs premium option
• or a stack for QuickBooks/Xero + COGS tracking
