E-Commerce Bookkeeping for Online Sellers
Bookkeeping for Amazon, TikTok Shop and Shopify sellers — know your real profit.

What is e-commerce bookkeeping?
E-commerce bookkeeping matches your marketplace payouts from Amazon, TikTok Shop, Shopify and other platforms to the real sales, fees, refunds, shipping and cost of goods behind them. The result is a true monthly profit number instead of just your bank deposits. Northlane Financials does this for US online sellers every month.

FAQ
E-Commerce Bookkeeping FAQs
Why doesn't my bank deposit match my sales?
Marketplaces take out fees, refunds, ads and shipping before paying you. We break each payout back into those parts.
Do marketplaces collect Texas sales tax for me?
Under Texas law, marketplace providers generally collect and remit sales tax on marketplace sales. Sales through your own website may still be your responsibility. We'll review your setup.
Do you track inventory?
Yes. We track inventory purchases and cost of goods sold so your profit is accurate.
