Amazon Accountants: What They Do and Why You Need One

F‍ast forward from the Jeff Bezos selling out of his garage in Seattle-Amazon has come quite a far way. As such, selling on Amazon can get overwhelming quickly. One month, your sales are up. The next month, you're wondering where all the money went. Too often, your profits don’t line up with what you expected.

If that sounds familiar, you’re not alone.

Amazon has completely changed how we sell online, but it’s also added a whole new layer of financial complexity. You have to deal with knowing how to discount and increase sales on Amazon Prime day, which in 2025, had sales that were double (!) Black Friday,  unpredictable Amazon FBA fees, shifting sales tax rules, inventory spread across random warehouses, and confusing settlement reports. It’s a lot to manage - especially when you're trying to grow your business.

“Selling on Amazon is easy. If you struggle, I really have to question your IQ.If you made it this far, you are either laughing or super upset with me. Obviously, I’m kidding.  (Jon Elder)

Most sellers begin their Amazon accounting journey the same way. They rely on spreadsheets, or maybe they experiment with some well-known accounting software - all while relying on a general accountant.

But usually, if the seller isn’t familiar with ecommerce accounting, they will choose an accountant or bookkeeper with a strong reputation in a traditional business. However, the seller soon realizes that regular bookkeepers - and most accounting software - don’t cut for Amazon reports. It may work for a while. But typically, it breaks down pretty fast.

Because the truth is, Amazon isn’t just another sales channel. It’s an ecosystem all its own. And if you want to run your business with real clarity and control, you need someone who actually understands how it works. In other words, an ecommerce accountant who specializes in Amazon.

In this guide, we’ll break down what Amazon accountants do, why that expertise matters, and how the right partner can help you make sense of the chaos and keep more of what you earn.

What Is an Amazon Accountant?

An Amazon accountant is like a financial translator for your Amazon business. Traditional CPAs are great for brick-and-mortar stores or service-based businesses, but Amazon is its own animal, and it speaks a different language. That’s where specialists come in.

An Amazon accountant understands the unique quirks of bookkeeping for Amazon sellers. Not just that payouts come every two weeks, but how those settlements are structured, why the numbers never quite match your sales dashboard, and how to sort through the maze of fees, returns, and adjustments Amazon bundles into each deposit.

You need specialized Amazon accountants to break down the difference between a standard fulfillment fee and one that’s triggered by oversized packaging or off-peak storage. Unlike regular accountants, Amazon specialists stay ahead of things like long-term FBA storage fees. They know how referral fees vary by category, and they can help you see how those changes actually impact your margins.

In short, they know how Amazon works, and they know how to make the numbers make sense, so you can actually run your business with confidence.

Why Traditional Accountants Fall Short

Imagine this: you finally decide to bring in a professional and hand your Amazon reports over to your trusted accountant. A few minutes in, you’re both looking at your Seller Central dashboard, and they hit you with, “Wait—Amazon just takes money out whenever it wants?”

It's not that your accountant isn't good at their job. They probably are. It's just that Amazon accounting isn’t like anything they’re used to.

Take Amazon’s settlement system. Most accountants expect clean transactions—sell a product for $100, you get $100. Simple. But Amazon? It rolls two weeks of sales, returns, fees, and adjustments into one big deposit that doesn’t match anything on the surface. You might get $3,847.63 deposited into your account, but that actually represents $5,200 in sales, minus returns, minus referral and FBA fees, minus ad costs, plus a few reimbursements.

Then there’s the mountain of fees. Amazon has charges for everything: fulfillment, storage, long-term storage, returns, removals, and more. A traditional accountant might just group all that together as “Amazon expenses,” which doesn’t tell you much. It’s like tracking all your personal spending under “miscellaneous.”

Inventory and inventory management adds another layer. Most accountants are used to businesses with a single warehouse or retail location. But Amazon moves your inventory between fulfillment centers all over the country. So when your accountant asks for a physical inventory count, and you tell them your products are currently sitting in four different states - and maybe in transit somewhere - they’re understandably lost.

And then there's sales tax compliance, which is constantly changing and varies by state (and takes marketplace laws into account). For a traditional accountant who's used to handling local businesses, it can feel like trying to solve a puzzle with missing pieces.

The bottom line: traditional accountants are great for a lot of businesses. But Amazon isn’t just another business. It plays by its own rules, and that requires someone who knows how to keep up.

Now we're getting to the good stuff—what these Amazon accounting wizards actually do to make your life easier and your business more profitable.

Core Services

1. Making Sense of Amazon’s Fees

As we noted above, Amazon's fee structure is notoriously complex and constantly changing. An Amazon accountant doesn't just track those charges; they organize and explain them in ways that actually make sense for your business. No more mystery deductions. You'll finally get clarity on what's helping or hurting your bottom line, and you will have the opportunity to optimize and see where you are bleeding cash.

“With all of these new way to fee us to death, and the lack of actual visibility, I am scared to even do fba anymore” (User writing on Seller Central)

2. Financial Reports You Can Actually Use

Standard profit-and-loss statements aren’t much help when you’re selling across multiple categories, marketplaces, or seasons. Amazon accountants customize your reports to show profitability by SKU, channel, or time period. Wondering if your Q4 strategy paid off or if a certain product line is carrying the weight? These reports tell you, in plain terms, what’s working and what’s not. No more cross-financing, folks.

3. Sales Tax Compliance Without the Stress

Sales tax compliance is complicated, and it's easy to get wrong. Amazon accountants handle the complexity so you don't have to worry about missing deadlines or filing requirements.

4. Inventory Tracking That Makes Sense

Your inventory is probably sitting in warehouses across multiple states, and it’s constantly moving. Amazon accountants keep tabs on it all. They track inventory flow, ensure you’re reimbursed for lost or damaged items, and make sure your cost of goods sold is presented accurately. You’ll always know where things stand without having to dig through spreadsheets or Seller Central.

5. Real Financial Accounting (Not Just Guesswork)

Many sellers use basic accounting methods that can hide real problems with their business. Amazon accountants use proper accounting practices that give you a more accurate view of your business performance and help you make better decisions for the future, giving you great P&L, balance sheets, and cash flow statements, to make real-time business decisions.

Advanced Services

1. Multi-Channel Clarity

Selling on Amazon is one thing. Selling on Amazon plus Shopify, Walmart, and eBay is another. Welcome to the world of multi-channel. Amazon accountants help you analyze the performance of each channel, so you know which ones are driving profit and which might be more hassle than they’re worth. Multi-channel just for the sake of multi-channel is usually not worth it. If the channel isn’t performing, it probably won’t add too much exit value in of itself.

2. Forward-Looking Financial Planning

It’s not just about reporting the past. Great Amazon accountants help you forecast cash flow, plan for big inventory purchases, and navigate Amazon’s payout schedule. And as we all know, direct-to-consumer businesses are super inventory-heavy, so being on top of this is crucial. They also offer proactive tax planning to help you minimize your liability, not just react to it once the year is over.

Benefits of Hiring an Amazon Accountant

Let’s talk about what this actually means for you. Because if you’re building a business, you need the right support behind the scenes.

1. Know Exactly Where Your Money’s Going

No more guessing. Just clear, accurate numbers that help you make smarter decisions. With an Amazon accountant, you get real visibility into your cash flow. You’ll know what’s driving your profits, where costs are creeping up, and whether a big deposit actually reflects strong performance, or just delayed payments from earlier sales.

2. Save Hours (and Your Sanity)

Reconciling Amazon reports and cleaning up spreadsheets might work when you're just starting. But as you grow, that busywork eats up hours you could spend launching new products, improving listings, or…just taking a weekend off. An Amazon accountant takes it off your plate so you can focus on the work that actually moves your business forward. Let’s be honest. Most normal people don’t like accounting (I’m a CPA, so I have the right to say this).

3. Recover Lost Revenue

It’s easier than you think to leave money on the table. Whether it’s missed reimbursements, unclaimed deductions, or fees that could’ve been avoided, a sharp Amazon accountant will spot it. They know where sellers typically lose money. In many cases, they pricing covers itself just by catching what others miss.

4. Stress Less at Tax Time

No more Prozac before filing. With proper monthly bookkeeping and sales tax tracking in place, tax season becomes routine instead of a crisis. An Amazon accountant keeps you ahead of deadlines and out of trouble.

5. Make Decisions Based on Real Data

Gut feelings only go so far. A good accountant helps you move from “I think this product is doing well” to “This SKU has a 23% profit margin after all fees.” You’ll know what’s profitable, where to cut costs, and how your business is really performing month over month. That kind of insight is how you grow with confidence.

Knowing your contribution margin is the way to go.

6. Build a Business That’s Ready to Scale

DIY accounting might be fine at minimal sales, but once you hit $100K or $1M, it’s a different story. Systems that worked early on start to break down. An Amazon accountant helps you build a financial foundation that supports growth, so you’re not constantly playing catch-up as your business levels up.

When to Hire an Amazon Accountant

How do you know when it’s time to bring in an expert? There’s no magic number, but there are some clear signs that you’ve outgrown the manual DIY approach.

Warning Signs to Watch For

Suppose you're constantly second-guessing your numbers, missing tax compliance deadlines, spending time-consuming hours on bookkeeping than on growing your business, or finding discrepancies in your revenue reporting and cash flow. In that case, it's probably time to get help. Houston, we have a problem.

Cash flow problems are a big red flag, but all too often, it’s not because your business is failing. It’s because you don’t have a clear view of where your money is going.

Sales tax regulations and compliance issues are also major warning signs. If you're unsure whether you need to register in other states, or if you're feeling lost on what Amazon handles vs. what you still need to do yourself, it's time to call in someone who knows the rules. The cost of fixing compliance mistakes later is almost always higher than doing it right from the start. Not fun, but this is necessary.

Milestones That Make It Worth It

There are natural points in your business growth where hiring an Amazon accountant just makes sense.

• Hitting $100,000+ in annual revenue
• Expanding to multiple marketplaces
• Launching multiple product lines

At these stages, your finances get more complex, and so do the risks of getting it wrong. Bringing in a professional helps you stay organized, compliant, and in control as you scale.

How to Choose the Right Amazon Accountant

All accountants are equal, but some are more equal than others. Especially when it comes to the Amazon ecosystem.

Here’s how to find ones who actually know what they’re doing.

Look for Amazon or Ecommerce-Specific Experience

Start by narrowing your search to accountants who actually work with Amazon sellers. A general small business CPA might be great at traditional companies, but Amazon is its own thing. Look for someone who understands FBA fees, Seller Central reports, and all the moving parts that come with selling on the platform. Experience matters—and so does fluency in marketplace accounting (hint, don’t take someone entry level- but rather, a senior accountant). Looking at Amazon accountant directories is a good place to start.

Ask the Right Questions

Don’t be afraid to dig in during the discovery call. A few smart questions can reveal whether they’re the right fit:

• How many Amazon sellers do you currently work with?
• What’s your experience with FBA-specific accounting?
• How do you handle Amazon settlement reconciliation?
• What’s your approach to sales tax compliance?
• How do you track inventory across multiple channels?
• Can you share references from other Amazon or ecommerce clients?

If they hesitate or give vague answers, keep looking.

Make Sure They Know the Right Tools

A good Amazon accountant should be comfortable with tools built for ecommerce. You want someone who can make your numbers accurate and efficient. Manual data entry shouldn’t be part of the deal.
