Why online store finances are different
Generic bookkeeping misses the details.
These are the areas where e-commerce most often need more than a standard setup.
Payouts aren’t sales
Marketplace payouts net out fees, refunds and reserves. Gross sales and fees must be recorded separately.
Inventory ties up cash
Purchase orders, freight and landed costs need tracking to know true COGS.
Ad spend moves fast
Advertising is often the largest cost after inventory and must be tied to channels.
Sales tax follows your customers
Selling across states creates sales tax obligations to track carefully.
