Quick Answer

Do Amazon or Shopify sellers need to worry about sales tax in states they don't live in?

Generally, yes, once your sales into a given state cross that state's threshold, you can have a sales tax obligation there regardless of where your business is based. The specifics genuinely vary by state and change over time, which is exactly why this needs real attention from someone tracking your actual sales, not a guess based on what worked last year.

The Real Impact of Getting Your Books Right

The number that matters most to an online seller isn't revenue, it's true profit per product, after Amazon or Shopify takes its cut, after shipping and fulfillment costs, after the cost of the product itself. A lot of sellers are flying on gross sales numbers that look healthy while certain SKUs are quietly losing money once every fee is accounted for. Once your books actually break out cost of goods, platform fees, and shipping separately, you can finally see which products are worth pushing and which ones are worth dropping.

Multi-state sales tax exposure is the other place we see sellers get caught off guard. It's easy to grow into new states through Amazon's fulfillment network or organic Shopify sales without ever noticing you've crossed a threshold somewhere. Finding out from a state notice, rather than from your own records, is a genuinely unpleasant surprise and usually a more expensive one than staying ahead of it would have been.

And clean records change how you buy inventory. Instead of reordering by gut feeling or bank balance, you can look at actual turnover and margin by product and platform, and make a purchasing decision based on what's really selling and what's really profitable, rather than what feels like it's doing well.

Common Questions

Frequently Asked Questions

Do I need to worry about sales tax if I sell on Amazon across the whole country?

Generally, yes, once your sales in a given state cross that state's threshold, you can end up with a sales tax collection and filing obligation there, even if you've never set foot in it. The rules vary by state and change often, and marketplace facilitator laws mean Amazon sometimes collects and remits on your behalf in certain states but not others. This is exactly the kind of thing that's too easy to get wrong by guessing, so we look at your actual sales footprint and help you understand where you may have exposure.

How do you track inventory across multiple platforms?

We pull sales and inventory data from wherever you sell, whether that's Amazon, Shopify, Etsy, or a combination, and reconcile it against your actual cost of goods so your books reflect what's really happening across every channel, not just one. The goal is a single, accurate picture of your inventory value and turnover, instead of separate numbers in separate dashboards that never quite agree with each other.

What counts as cost of goods sold for an online seller?

It's more than just what you paid your supplier. Shipping the product to you, freight and customs if you import, packaging, and often a portion of fulfillment costs all factor into a true cost of goods sold figure. Get this wrong and your profit numbers look better on paper than they actually are, which makes it hard to price products correctly or know which SKUs are actually worth reordering.

Can you help if I sell on both Shopify and Amazon?

Yes, that's a common setup and one we're used to working with. Each platform reports sales, fees, and payouts differently, so we consolidate everything into one clean set of books instead of leaving you to reconcile two or three separate systems on your own.

How are Amazon and Shopify fees supposed to be recorded?

Referral fees, FBA storage and fulfillment fees, payment processing fees, and advertising spend should all be broken out and tracked as their own expense categories, not lumped together or netted against revenue without detail. When they're recorded properly, you can actually see how much of each sale is going to the platform versus staying with you.

Do you help with 1099-K reconciliation?

Yes. The 1099-K a platform sends you reports gross payment volume, which is not the same as your revenue or your profit. We reconcile that form against your actual books so the numbers on your tax return make sense and match what the platform reported, rather than raising questions later.

I'm just starting to sell online. Is it too early to get help with bookkeeping?

It's actually the best time. Setting up clean tracking from your first sale, rather than trying to reconstruct a year of transactions later, saves a lot of headache and makes it much easier to understand whether the business is actually profitable as you scale it.
