E-commerce Bookkeeping

Selling online is great until the payout hits your bank account and it does not match what you thought you earned.

That is normal in ecommerce. Shopify, Amazon, Etsy, WooCommerce, Stripe, PayPal, and other tools all handle payouts, fees, refunds, taxes, and timing differently. If you only look at the deposit, you miss the real story.

That is where we help. Our E-commerce Bookkeeping service is built for sellers who want clean books, real margin visibility, and monthly numbers they can actually use.

Stripe’s standard U.S. domestic card rate is 2.9% + 30¢
PayPal business card processing starts at 2.89% + $0.29, depending on the checkout setup
Economic nexus can be triggered by sales thresholds and, in some states, transaction counts
WooCommerce currently shows 7+ million active installations

Why Ecommerce Bookkeeping Gets Messy

Ecommerce is not just income minus expenses.

You are dealing with:

Sales across multiple channels
Payout timing that does not match order timing
Marketplace and processor fees
Refunds, returns, and chargebacks
Shipping labels and fulfillment costs
Inventory purchases that do not belong entirely in one month
Sales tax obligations that can change as volume grows

That is why ecommerce owners so often feel confused by their numbers. Amazon itself says its Payments reports break activity down by settlement period, fees, refunds, and fund transfers. Shopify explains that payout timing depends on settlement rules, cutoff timing, weekends, and bank processing. Etsy says fees are deducted inside the payment account before deposit. If you only look at the bank feed, you are already behind.

We keep the books organized so your reports reflect what actually happened, not just what hit the bank.

Prepare reports for sales tax filing or handoff to your tax service

What Clean Ecommerce Books Should Show

Area	What it should show
Sales	Gross sales by channel, not just total deposits
Fees	Marketplace, payment, fulfillment, and app fees broken out clearly
Refunds	Returns and chargebacks matched to the correct period
Inventory	Purchases and COGS reflected correctly, not dumped into one month
Taxes	Sales tax liabilities visible before filing deadlines arrive
Profitability	Actual gross margin and operating margin, not wishful thinking

Payouts, Fees, and Why Deposits Mislead Sellers

One of the most common ecommerce mistakes is treating the bank deposit as sales.

That breaks the books fast. Shopify says U.S. payouts arrive based on settlement time and bank processing, and it explains that charges captured on weekends are grouped together. Etsy says payment processing fees are deducted before deposit. Amazon says seller payment reports show settlement activity, fees, refunds, and transfer details. Those are not bookkeeping edge cases. They are the normal workflow.

That is why we reconcile ecommerce activity back to platform reports, not just the bank feed.

Inventory and COGS Matter More Than Most Sellers Think

A lot of ecommerce businesses still treat inventory purchases like ordinary monthly expenses. That can make a profitable store look weak one month and overly profitable the next.

We help sellers build cleaner inventory and cost of goods sold workflows so the P&L makes more sense. That can include purchase tracking, month-end inventory adjustments, and channel-specific COGS support.

If you use a connector, that helps too. A2X says it can calculate COGS by settlement period. Its Shopify and Amazon support articles explain how cost data can feed inventory and COGS postings. That does not replace judgment, but it can reduce manual cleanup.

Sales Tax Still Gets More Complicated as You Grow

Ecommerce sales tax is not a “set it and forget it” issue. Avalara’s current nexus guide notes that economic nexus can be triggered by sales revenue and, in some states, transaction counts. Exempt sales can count toward thresholds in some states too.

That means a store can grow into new filing obligations quietly. We help keep the books ready for sales tax filing or handoff to tools like Avalara or other sales tax services.

Shopify also says the Shop channel handles U.S. tax collection and remittance differently from the main online store checkout. Those details matter if a seller assumes every channel behaves the same way.

Works With Your Platforms and Tools

We work with the tools ecommerce sellers already use, including:

If it connects cleanly, exports well, or can be reconciled with the right report, we can usually make it work.

Save Time. Stop Guessing.

The point of ecommerce bookkeeping is not just tax prep. It is clarity.

You should be able to see:

Which channel is actually the most profitable
Whether ad spend is helping or just inflating revenue with weak margin
How much cash needs to stay in the business for inventory and tax obligations
When fees, refunds, and returns are eroding margin
Whether the business is scaling profitably or just getting louder

One of the biggest wins for ecommerce sellers is simply getting from “I think we are doing well” to “I know where the profit is.”

Frequently Asked Questions

Why doesn’t my Shopify or Amazon deposit match my sales?

Because the deposit is usually net of fees, refunds, adjustments, taxes, and payout timing differences. That is why ecommerce books need platform reports, not just bank feeds.

Do you work with Shopify, Amazon, Etsy, and WooCommerce?

Yes. We regularly support sellers using Shopify, Amazon, Etsy, and WooCommerce.

Can you help with inventory and COGS?

Yes. We help sellers record purchases, track inventory-related activity, and build cleaner COGS reporting so gross margin is more meaningful.

Do you file sales tax?

We can prepare the books and reports for filing, and we can work alongside your sales tax service or tax preparer. The exact filing setup depends on your states and platform mix.
