- True landed costInventory and COGS right
- Profit by channelNot just total revenue
Big Accountants provides ecommerce bookkeeping services to US online sellers on Shopify, Amazon, Walmart, Etsy, eBay and their own stores. We turn messy marketplace settlements into clean books: gross sales, fees, refunds, advertising, inventory and sales tax all recorded in the right accounts.
Most ecommerce books go wrong in the same place. A payout lands in the bank as one net number, and it gets booked as revenue. That hides your real sales, overstates or understates profit and makes sales tax and income tax harder than they need to be. We record the full picture behind every deposit.
- Gross sales by channel, not net deposits
- Marketplace and payment fees by type
- Refunds, chargebacks and returns
- Landed cost of goods sold
- Sales tax collected by marketplaces and by you
Why Ecommerce Bookkeeping Needs Specialists
Online sales keep growing, and so does the complexity behind each sale. Federal data and tax rules show why generic bookkeeping falls short.
What Our Ecommerce Bookkeeping Services Include
Built around how online sellers actually get paid, ship and sell.
Payout reconciliation
Every Shopify, Amazon, Walmart, PayPal and Stripe payout broken into its parts and matched to the bank.
Multichannel sales
Sales recorded by channel and marketplace, so you can compare them fairly.
Fee tracking
Referral, fulfillment, storage, payment and subscription fees coded separately.
Inventory and COGS
Purchases, freight, duties and landed cost tracked into cost of goods sold.
Sales tax records
Marketplace collected and seller collected sales tax kept separate by state.
Advertising spend
Amazon, Meta and Google ad spend tracked against the sales it drives.
Refunds and chargebacks
Returns, chargebacks and reserves recorded so revenue is not overstated.
Profit by channel and SKU
Contribution margin by channel, product and brand every month.
How a Marketplace Payout Should Be Recorded
A single deposit hides several transactions. This is how we break a typical settlement down in your books.
| Line in the settlement | Where it goes in your books | Why it matters |
|---|---|---|
| Gross product sales | Revenue, by channel | Shows true sales volume |
| Shipping charged to customers | Shipping income | Keeps product margin clean |
| Marketplace referral fees | Selling fees expense | Reveals the real cost of each channel |
| Fulfillment and storage fees | Fulfillment expense or COGS | Drives landed cost and margin |
| Refunds and returns | Returns and allowances | Prevents overstated revenue |
| Sales tax collected by the marketplace | Tracked, not your revenue | Keeps tax reporting accurate |
| Net payout to bank | Cleared against the deposit | Proves the books tie to the bank |
This is general information, not tax advice. Sales tax obligations depend on the states you sell into and their rules for remote and marketplace sellers.

- Amazon or Shopify fees lumped into one expense line
- Inventory expensed when bought, not when sold
- No idea which channel or product actually makes money
- Sales tax collected by marketplaces mixed with your own

Ecommerce Bookkeeping FAQs
What are ecommerce bookkeeping services?
Ecommerce bookkeeping services record and reconcile the finances of online sellers. They break marketplace and payment processor payouts into gross sales, fees, refunds and taxes, track inventory and cost of goods sold, and report profit by channel and product.
Why should I not record payouts as revenue?
A payout is a net figure after fees, refunds and sometimes sales tax have been taken out. Recording it as revenue understates your sales and hides your real costs, which distorts margins and can complicate your tax return.
Which platforms do you work with?
We work with Shopify, Amazon, Walmart, Etsy, eBay, WooCommerce, PayPal and Stripe, recording them in QuickBooks Online, Xero or Zoho Books.
Do you handle inventory and cost of goods sold?
Yes. We track inventory purchases, freight, duties and other landed costs, and record cost of goods sold as products sell, so your gross margin reflects reality.
Do you file sales tax returns for ecommerce sellers?
We keep marketplace collected and seller collected sales tax separate by state, so your sales tax position is clear. Filing in each state can be added to your scope where you are registered.
Will I receive a Form 1099-K?
Payment platforms generally issue Form 1099-K when payments to you exceed $20,000 and more than 200 transactions, according to the IRS. We reconcile any 1099-K you receive to your books so your return reports income correctly.
How much do ecommerce bookkeeping services cost?
Cost depends on the number of channels, order and SKU volume, inventory complexity and reporting needs. We offer a competitive fixed monthly fee, hourly billing or per task pricing, quoted in writing after a free call.
Can you show profit by product or channel?
Yes. We report contribution margin by channel and, where your data allows, by product or brand, after fees, fulfillment and advertising.
