Amazon Seller Bookkeeping for Non-US Residents: How to Stay Compliant and Protect Your Margins

Amazon is one of the big leagues of e-commerce, and the numbers back it up. It hit $717 billion in net sales revenue in 2025. That same year, the US alone recorded 2.8 billion visits. This translates to unparalleled access to a global customer base backed by a world-class logistics engine for sellers.

These figures also mean a huge opportunity for international sellers. Through the Fulfillment by Amazon (FBA) model, you can expand to the US. You source products, ship them to a warehouse, and let a trillion-dollar infrastructure handle the logistics.

While access is easy, staying compliant and profitable is not. Fortunately, efficient bookkeeping can help you track profit as well as stay compliant.

Dive in to know what Amazon bookkeeping is, its importance, and how you can maintain compliance while protecting your margins.

What is Amazon Bookkeeping and Why is it Important?

Bookkeeping is the systematic tracking of a seller’s financial health, encompassing everything from sales revenue to shipping logistics and platform fees. Beyond helping you stay compliant with US tax laws, bookkeeping protects profit margins from hidden expenses and builds the enterprise value of the business.

Financial Reconciliation and the Gross versus Net Conflict

A common pitfall for international sellers is recording only the net Amazon disbursement rather than gross sales. As Amazon deducts fees and advertising costs upfront, the net deposit hides the true cost of doing business.

To gain a clear view of your performance, you must record gross revenue and categorize every deduction (shipping, storage, returns) as an expense. Professional bookkeeping services make sure your Amazon payouts match your bank deposits accurately. This gives you a clear picture of your actual profits, keeps your business tax-compliant, and ensures you stay in control of your money.

Options such as doola bookkeeping service can help establish a routine reconciliation process to align your records, which makes it easier to identify discrepancies and keep your finances accurate.

Accrual Versus Cash Accounting for International Scaling

Selecting an accounting methodology is a cornerstone decision for any international Amazon seller. While cash accounting (tracking money only as it moves) is easy to manage, it generally falls short for e-commerce models involving heavy inventory.

The accrual method is the industry benchmark for sellers. Recording revenue at the point of sale and expenses as they occur rather than waiting for bank transfers aligns your cost of goods sold (COGS) directly with the income they generated. This provides a precise snapshot of real-time profitability.

Understanding Tax Status for Non-US Residents

The most complex part of selling on Amazon from abroad is understanding US taxes. Many people believe that if they do not live in the US, they do not have to pay US taxes. That isn’t the case.

If you use the FBA program, your products sit in a warehouse somewhere in America. This physical presence often gives you what the law calls a “Nexus.” It means you are “Engaged in a Trade or Business” (ETBUS) in the US.

When you sell products to US customers through FBA, the money you make is considered Effectively Connected Income (ECI). ECI is taxed at the same graduated rates as US citizens.

To report this income, you must file Form 1040-NR, while foreign corporations file Form 1120-F. You can deduct your business expenses, like shipping, Amazon fees, and the cost of your products, from your total sales before you calculate the tax. Proper bookkeeping will help you do that.

To establish your status as a non-US person with Amazon, you must complete the tax interview in Seller Central. This process generates either Form W-8BEN (for individuals) or Form W-8BEN-E (for entities). This prevents Amazon from automatically withholding 30% of your sales for US taxes.

Tips to Help You Stay Compliant and Protect Your Margins

Here, we’ll share a few tips that can help you stay compliant and protect your margins:

1. Track Your Inventory Correctly

Inventory is often the biggest expense for an Amazon seller. If you do not track it correctly, you will never know your true profit.

One simple way to track inventory is the FIFO method. FIFO stands for First-In, First-Out. It means the oldest items are sold first. This is helpful if prices change over time. It keeps the cost records accurate. Another method is LIFO. LIFO stands for Last-In, First-Out. Most sellers prefer FIFO for Amazon.

Amazon provides a wealth of data, of which the Inventory Report in Seller Central is one of the most critical for your bottom line. This report monitors exactly what is sitting in fulfillment centers, allowing you to identify overstock before it becomes a liability.

2. Separate Personal and Business Expenses

It’s tempting to use your personal credit card for a quick software subscription or a small sample order. But for a non-resident, this is a compliance nightmare.

Mixing funds, often called commingling, makes it nearly impossible to prove your business expenses to tax authorities. It also makes your bookkeeping twice as hard because you have to pick through your grocery bills to find that one Amazon PPC charge.

Open a dedicated business account to get a US-based bank account or a multi-currency account. This allows you to receive USD from Amazon and pay expenses without constant conversion fees, making bookkeeping so much easier.

3. Understanding Amazon’s Fee Structure

Amazon charges fees for everything. To protect your margins, you have to understand how these fees work. They change often, and if you are not careful, they can eat 30% to 50% of your revenue.

Amazon’s referral fee is a category-based commission, typically 15%. FBA fulfillment fees cover picking and shipping based on size and weight. Auditing your dimensions monthly is important, as a single inch can trigger a more expensive size tier.

Additionally, the 2024 low-inventory level fee applies a per-unit surcharge if your stock falls below 28 days of supply over a 30 or 90-day average. To avoid this, you should try to keep at least 35 days of stock at Amazon at all times. If you are a new seller, you are exempt from this fee for your first year.

Conclusion

For a non-US resident, profitability and compliance are inseparable. You cannot sustain one without the other. Poor compliance leads to high taxes that erode margins, while poor bookkeeping obscures the low profits that eventually kill a business.

Manage both well, and you create a stable, scalable business foundation. Remember, every dollar you find in your books by spotting an overcharge or a high storage fee is a dollar that goes straight back into your pocket.

You’ve done the hard work of launching a brand in the world’s biggest market; now, it’s time to make sure you keep the rewards.
