Accounting Built for Amazon FBA Sellers
FBA inventory creates sales-tax nexus in states you have never set foot in, and Amazon settlements are a mess to reconcile. We handle the bookkeeping, nexus and filings so you can focus on selling.
- Settlement & payout reconciliation
- Multi-state sales-tax nexus tracking
- Inventory & COGS done right
- Filed by a CPA & EA team
Selling on Amazon creates accounting problems most bookkeepers never see: settlements that aren't really revenue, and inventory that creates sales-tax nexus in states you've never visited. Here's how we handle it.
Why generic bookkeepers get Amazon wrong
A standard bookkeeper sees your Amazon payout and books it as revenue — but that deposit is already net of fees, refunds, and reserves, so your books and tax end up wrong.
- Reconciled from the settlement report up, not the bank deposit
- Fees, refunds, reimbursements, and reserves each in the right place
- Accurate COGS so your profit and tax are correct
Sales-tax nexus for FBA sellers
Storing inventory in an FBA warehouse can create physical nexus in that state, and your sales volume can create economic nexus in others — sometimes dozens at once.
- We assess where your inventory and sales create nexus
- Register you where you owe and set up collection
- Handle ongoing filings so a gap never becomes a back-tax bill
Check your exposure with the sales-tax nexus checker.

Frequently asked questions
Do I need to collect sales tax in every state I have FBA inventory?
Storing inventory in a state can create physical nexus there, so you may need to register and collect. We assess your specific footprint and handle registrations.
Can you reconcile my Amazon settlements?
Yes. We turn Amazon settlement reports into clean books, correctly splitting out fees, refunds, reimbursements, and payouts.
Do you work with foreign-owned Amazon businesses?
Yes. We regularly handle foreign-owned US LLCs selling on Amazon, including the related federal filings.
How much does accounting for an Amazon seller cost?
Plans start from $149/mo depending on order volume and complexity. You get a flat quote before any work begins.

Filing FAQ
My 1099-K is way higher than what hit my bank. Which do I report?
Neither, exactly — you report gross sales and then deduct refunds, Amazon fees and reserves so the return reconciles to both the 1099-K and your deposits. That bridge is what clean books are for.
Amazon collects sales tax for me — do I still file anything?
Often yes. Marketplace facilitator laws cover Amazon's collection, but several states still expect a registered seller to file returns (even zero-due ones), and your own-site sales are entirely on you.
