What's the difference between general and e-commerce accounting software?

General accounting software manages core finances, while e-commerce accounting systems must also handle high-volume transactions, inventory COGS, platform fees, and complex sales tax. Many businesses use a general ledger (like QuickBooks) paired with a specialized connector app (like A2X) to get the best of both worlds.

Why is inventory and COGS tracking so important?

Accurate inventory and Cost of Goods Sold (COGS) tracking is critical for knowing your true profitability and for tax compliance. It tells you the direct cost of the products you sell, which is subtracted from revenue to determine your gross profit. Without it, you are flying blind on your margins.

Do I need a separate app for sales tax?

It depends on your scale. Most accounting platforms have basic sales tax features, but businesses selling across many US states often need a dedicated tool like TaxJar or Avalara. These tools automate calculations and filings for thousands of tax jurisdictions, a task that becomes impossible to do manually.

How to choose

1. 1First, map your sales channels (e.g., Shopify, Amazon FBA, Etsy) and confirm the software integrates directly or via a reliable connector.
2. 2Second, evaluate your inventory complexity. If you have multiple warehouses, use bundles, or need landed cost tracking, choose a system with advanced inventory modules like NetSuite or a dedicated inventory management add-on.
3. 3Third, assess your transaction volume. A store with 100 orders a month has different needs than one with 10,000. High-volume sellers must prioritize platforms that can scale without performance issues.
4. 4Finally, consider your in-house expertise. If you don't have a dedicated finance person, a more automated solution like Finaloop or a service-based option like Bench might be a better fit than a complex DIY platform.

What is the best accounting software for Shopify sellers?

QuickBooks Online is the best accounting software for most Shopify sellers when combined with a connector app like A2X or Synder. This stack provides a standard, powerful general ledger while correctly handling Shopify's batched payouts, fees, and sales tax details.

Can I use Xero for my e-commerce business?

Yes, Xero is an excellent choice for e-commerce, particularly for businesses that sell internationally. Its native multi-currency support is stronger than competitors, and it integrates with all major e-commerce platforms and connector applications.

Is Excel good enough for e-commerce accounting?

Excel is not sufficient for e-commerce accounting beyond the very earliest hobbyist stage. It is prone to manual errors, cannot scale with transaction volume, provides no real-time data, and lacks the necessary features for inventory tracking, sales tax compliance, and financial reporting.

How much should I expect to pay for e-commerce accounting software?

Expect to pay between $30 to $150 per month for a core accounting platform and a necessary connector app. All-in-one platforms for larger businesses, like NetSuite, can cost over $1,000 per month.
