Accounting in Ecommerce and The Workings Behind
Ecommerce presents unique challenges to businesses. The supply chain is complex with multiple moving parts. Accounting in ecommerce needs to pull together data from diverse touchpoints spanning from purchase or manufacturing to sale, meaningfully.
Cash flow management can be particularly challenging with varying fund disbursal policies for the different platforms like Amazon, Shopify, eBay, and Etsy.
Today, most businesses sell on their website as well.
There are multiple sales and fulfillment channels and payment processors, all generating their streams of data.
With a customer base potentially spread across the globe, ecommerce companies also grapple with international logistics, tariffs, and taxation challenges.
Now we can easily see why specialized accounting is the need of the hour in ecommerce. It’s the pivotal element that ensures fiscal control, efficient cash flow, compliance, and effective forecasting.
This is exactly why U.S online stores are prioritizing ecommerce accounting as key to sustainable business growth in 2025.
Challenges in Ecommerce Accounting and How to Succeed
Accounting complexity does not exist in isolation in ecommerce. It impacts multiple crucial areas of the business as listed below.
Multiple sales channels
Today, almost all businesses sell on multiple channels, including the brand website, social media, and marketplaces like Amazon, eBay, Etsy, and newer platforms like Temu and Shein.
These channels have different terms, payment gateway integrations, and seller fees. Consolidating data from multiple channels is a laborious task, but essential for documentation hygiene, accuracy, and compliance.
So, what can you do to get a synchronized picture? How can you track multi-channel ecommerce data seamlessly?
- Centralized ecommerce ERP or Integration Platform
These platforms act like a central hub that pulls sales, inventory, customer, and shipping data from all your ecommerce platforms in real-time.
Wholesalers, manufacturers, and retailers need to record data only once in a single system, usually the ecommerce application, allowing for real-time flow into your back office systems like ERP. This ensures accurate sales data and forecasting.
Omnichannel fulfilment platforms integrate all your stores, manage inventory, and track transactions from a single dashboard. E.g.. NetSuite, Extensiv
Inventory Management
Keeping track of your products in e-commerce can be tricky, but it is super important. You need to know how much stock you have, how much it’s costing you, and make sure everything is updated across all your online stores. If the numbers are off, you could run out of products or end up with too much, both of which hurt your profits and customer trust.
Using inventory tools that connect with your accounting system can help you stay on top of things, give you real-time updates, and make your work a lot easier.
Tools like Linnworks, Zoho Inventory, and Sellbrite track and update stock levels across all channels to prevent overselling or stockouts.
Manage Returns and Refunds
Managing returns and refunds is another critical area in accounting in ecommerce.
With an integrated solution, you can track returns and refunds. This is a critical element of ecommerce, both a boon enhancing customer loyalty, and a bane causing bookkeeping headaches. When returns and refunds are not tracked, it results in faulty sales, inventory, expenses, forecasting, and tax data.
According to a National Return Federation report, collectively, consumers returned products worth a staggering $890 billion in 2024.
Returns aren’t just about getting an item back—they cost you real money. From return shipping and restocking to items losing value, handling returns can eat into your profits. It can cost retailers anywhere from 20% to 65% of the item’s original price to process a single return.
Every return affects your sales, stock levels, and how you track your money. If it’s not handled properly, it can adversely impact your financial reports.
Having a clear return policy and making sure your accounting system can handle returns smoothly helps keep everything accurate and under control.
Payment Processing
Ecommerce businesses use multiple payment processors like Stripe, PayPal, Square, Amazon Pay, and Braintree, each coming with their own payment structure and settlement periods.
Accounting for fees and reconciling payments can be time-consuming and complex. Integrated solutions can automate fee payments and reconciliation, providing accurate and clear visibility into cash flow, expenses, and revenue.
Optimizing payment processing is very important, both to ensure customer satisfaction and accounting efficiency.
Tax and compliance
Sales tax can get tricky in ecommerce. Different states and countries have different rules, and keeping up can be overwhelming. But getting it right is important—mistakes can lead to fines or legal trouble.
Using sales tax software that automatically updates rates can make things easier. And when in doubt, it’s smart to work with a tax expert who understands eCommerce.

Data Security and Regulatory Compliance
Ecommerce businesses deal with sensitive customer data, so keeping that information safe is crucial. Laws like GDPR and CCPA require strict data protection practices.
If this data isn’t properly secured, it can lead to legal trouble and harm your reputation. That’s why having strong cybersecurity measures and doing regular system checks is essential part of accounting in ecommerce—to protect both your business and your customers.

- Data should be collected through an explicit, consent-driven process
- Simple, clear, and direct privacy policies
