A Settlement Deposit Is Not Revenue
Almost every Amazon bookkeeping problem starts in the same place. Amazon pays you a single number every two weeks. That number is not your sales. It is your sales, minus referral fees, minus fulfilment fees, minus storage, minus advertising, minus refunds, minus reserves, plus whatever was released from the last reserve, net of tax Amazon collected and remitted on your behalf.
Post that deposit into your accounting software as one line of income and every downstream figure is wrong. Your revenue is understated, your expenses are invisible, your margin is fictional, and your tax position is built on a number that does not describe your business.
"The most expensive bookkeeping mistake in this business is not a missed deduction. It is running for two years on a profit number that was never real, and making inventory decisions with it."
Tom Reiter, Product Research & Operations Specialist
That is the job this category exists to do. It splits the settlement into its parts, posts them where they belong, and leaves you with books that reconcile against the bank. Everything else, sales tax filing, managed bookkeeping, tax forms, sits around that core problem.
Four Different Jobs, Often Confused
Sellers routinely shop for one of these and buy another. The table sets out how the main options position themselves, based on their publicly stated positioning and our own assessment as of September 2026. It is a shortlisting aid, not an exhaustive feature comparison, and a tool that is not credited with a capability here has not been assessed as lacking it. Pricing is deliberately not quoted because plans in this category change often, so check each vendor's own pricing page.
| Tool | Built around | Typically suits |
|---|---|---|
| A2X | Splitting Amazon settlements into itemised, reconcilable journal entries and posting them to QuickBooks Online or Xero | Sellers who work with a bookkeeper or accountant |
| Link My Books | Automated marketplace settlement summaries posted into Xero or QuickBooks with tax treatment applied | Multi-marketplace sellers wanting a connector alternative |
| SellerLedger | Standalone bookkeeping built specifically for online sellers, without a separate general ledger subscription | Solo sellers who want proper books at a low entry cost |
| Finaloop | A managed bookkeeping service combining software with a team that maintains the books for you | Brands that want the function outsourced entirely |
| TaxJar | Sales tax reporting, nexus tracking, and automated filing across US states | Sellers with multi-state registration obligations |
| QuickBooks Online / Xero | The general ledger itself, where the split settlement data lands and the accounts are closed | Almost everyone, as the destination rather than the connector |

Choosing Without Buying the Wrong Layer
The single most common mistake here is buying a connector when you needed a ledger, or a sales tax platform when your obligation was already being handled. Five steps that prevent both.
Your Accounting Stack Checklist
Decide who closes your books first
If an accountant or bookkeeper closes them, buy a connector that feeds the ledger they already use. If nobody does, you are shopping for bookkeeping software or a managed service, not a connector. Getting this order wrong is how sellers end up paying for a bridge to a ledger they never opened.
Insist on reconciliation, not categorisation
The test of a settlement tool is whether its entries tie exactly to the deposit that hit your bank. Summaries that approximately describe a payout create a reconciliation problem later, usually discovered in the week your return is due.
Check how inventory and cost of goods are handled
For a product business, cost of goods sold is where the real margin answer lives, and it is the piece most likely to be treated lightly. Ask specifically how a tool treats inventory purchases, landed cost, and units sitting in fulfilment centres before you commit.
Separate what Amazon collects from what you owe
Amazon collects and remits sales tax as a marketplace facilitator in the US states that have such laws, which as of 2026 covers all states with a statewide sales tax plus the District of Columbia. That does not automatically end your own registration, filing, or nexus obligations. Confirm your position with a qualified CPA rather than assuming the marketplace has closed the file.
Match the tool to your stage, and expect to change it
The right stack for a seller doing five figures is not the right stack at seven, and outgrowing a tool is not a failure of the tool. Pick for where you are now, and check whether your data can be exported cleanly before you rely on it for years.
Step four causes the most confusion in this category. Marketplace facilitator collection genuinely removed a large amount of work from sellers. It did not remove the obligation to know where you have nexus, and inventory sitting in fulfilment centres is one of the things that can create it.
On our sourcing: Tool descriptions are neutral summaries of each vendor's publicly stated positioning and our own hands-on assessment as of September 2026; they are not exhaustive feature lists, and no tool should be read as lacking a capability simply because it is not credited with one here. Pricing is deliberately not quoted because plans and tiers in this category change frequently, so check each vendor's own pricing page for current rates. The federal Form 1099-K reporting threshold of more than $20,000 in gross payments and more than 200 transactions for tax year 2026, described as restored under the One Big Beautiful Bill Act, is as reported in 2026 by TaxJar, GeekSeller, and ProAxis; some states set their own lower reporting thresholds. The description of Amazon collecting and remitting sales tax as a marketplace facilitator across US states with statewide sales tax, plus the District of Columbia, is as reported in 2026 and does not by itself remove a seller's registration, filing, or nexus obligations. Tax rules change and vary by state, entity type, and individual circumstances.
