Ecommerce books live or die on two things: clean revenue across every channel and accurate COGS. Shopify, Amazon, Etsy, and your own site each report deposits differently — net of fees, refunds, chargebacks, and reserves — so the deposit that hits the bank is never the sale. Real ecommerce accounting reconciles gross sales, fees, refunds, and payouts per channel, tracks inventory and cost of goods sold, and gives you margin you can actually trust.
Delaware adds a genuinely different tax picture. There is no state or local sales tax — nothing to collect from customers and no sales-tax return — which is a real draw for sellers and fulfillment operations. But two things still apply. First, Delaware levies a gross receipts tax on the seller: 0.0945%–1.9914% by business activity, on your total receipts after a monthly or quarterly exclusion amount, filed with the Division of Revenue. Second, when you ship into other states where you have economic or physical nexus, those states’ sales-tax rules apply — so QuickBooks has to track destination revenue and flag where registration may be required.
The common mistake is assuming “no sales tax in Delaware” means no tax obligations at all. TechBrot sets up multi-channel reconciliation, COGS, gross-receipts tracking by activity, and out-of-state nexus monitoring in your own QuickBooks file, keeps it accurate monthly, and hands clean numbers to your CPA, who files. Independent firm — not affiliated with Intuit Inc.; does not file Delaware or other states’ returns.
