A2X and Link My Books solve the same problem and disagree about almost everything else. Both take marketplace settlements and post them into your accounting system as clean journal entries instead of a pile of individual orders. The divergence is in geography, in which accounting products they will talk to, and in how far back they will reach. Pick wrong and you will discover the constraint six weeks into onboarding, which is the expensive time to find out.
Here is where the two actually part company, based on what each vendor publishes on its own site as of August 2026.
Accounting system support is the first hard filter
This is the shortest path to a decision and most comparisons bury it.
A2X integrates with QuickBooks Online, Xero and NetSuite. Link My Books integrates with Xero, supporting all regions and every plan except Cashbook, and with QuickBooks, but its pricing page is explicit that QuickBooks support covers QuickBooks Online plans only. No Desktop.
If your books live in QuickBooks Desktop or Enterprise, neither of these tools is your answer and the comparison ends here. That constraint sends a meaningful slice of established US sellers toward a different category of product entirely, one built around per-SKU sync into Desktop and Enterprise. ConnectBooks sits in that category, and so do several inventory-first platforms. If you are on QuickBooks Online or Xero, keep reading.
The NetSuite line matters more than it looks. A2X is the only one of the two that will follow a seller up into NetSuite, which is where brands tend to land somewhere past the point their QuickBooks file starts groaning. Choosing A2X buys you an exit ramp you may not need for three years.
Channel coverage: Link My Books is broader, A2X is deeper on price clarity
Link My Books lists eight sales channels: Amazon, eBay, Shopify, Etsy, Walmart (US only), TikTok Shop (UK and US), WooCommerce and Square. That Square line is unusual. It means a brand running both a Shopify store and a physical retail counter on Square POS can bring both into the same reconciliation, which is a real advantage for anyone with a shop, a market stall or a pop-up.
A2X publishes per-channel plans for Amazon, Shopify, Etsy, eBay, PayPal and Walmart, plus a separate multi-channel track. PayPal is the interesting entry there. A seller taking payments through PayPal outside a marketplace gets those payouts reconciled through the same tool, which Link My Books does not advertise as a standalone channel.
On pricing, A2X is straightforward about the entry point and Link My Books is not. A2X starts at US$29 per month for Amazon, Shopify, Etsy, eBay and PayPal, and US$79 per month for Walmart. Link My Books prices from an order-volume slider that computes in the browser, so there is no published figure to quote. You have to run the configurator yourself with your real order count and channel mix. That is a defensible design, since the answer genuinely depends on volume, but it makes side-by-side comparison harder and you should not accept a third-party blog’s Link My Books price as fact.
Historical data is where the gap is widest
If you are catching up rather than starting clean, this is your deciding factor.
Link My Books imports the last 90 days of settlements during the free trial, and once you are on a paid plan you can go back up to 24 months depending on tier, with additional history purchasable as a one-off fee. Two years of settlement history is a lot of runway for a seller who has been filing estimates and now needs to restate.
A2X handles historical imports too, but the depth is set per plan rather than published as a single headline number, so you should confirm the specific reach for the plan you are considering before you commit to a cleanup project. The general principle applies to both: the further back you reach, the more it costs, and nobody gives you unlimited history on an entry plan.
Tax handling splits the two along a national border
Link My Books is built by people who clearly spend their days in UK and EU VAT. The feature list includes HMRC VAT files attached to each entry in your accounting software, a product grouping system that applies standard, reduced and zero rates to different product sets, a guided tax wizard for sellers holding multiple EU VAT registrations or running PAN-EU, and a VAT audit view across channels. A UK seller on PAN-EU has a genuinely hard compliance problem and Link My Books has clearly been engineered against it.
A2X handles tax mapping too and is widely used on both sides of the Atlantic, but its public positioning leans harder on the settlement journal itself than on any one country’s tax regime. For a US-only seller dealing with marketplace facilitator rules rather than VAT registrations, that difference is mostly irrelevant. For a UK or EU seller it may be the entire decision.
The pricing model has a behavioural difference
Link My Books calculates your required plan from a rolling average order count, three months when you first join, growing to a twelve month rolling average as you stay. If your average crosses your plan’s limit, the company emails you and upgrades you automatically seven days later.
That design smooths seasonality, which is a real kindness to anyone whose December looks nothing like their February. It also means the upgrade is automatic rather than a decision you make. Read that as either convenience or loss of control depending on your temperament, but know it is happening.
Two things worth weighing that are not features
First, users. Link My Books includes unlimited additional users on its plans, so bringing your accountant and your bookkeeper into the tool costs nothing. If you work with an outside firm, per-seat pricing elsewhere adds up.
Second, marketplace standing. Link My Books shows a 5 out of 5 rating on the Xero Marketplace across more than 510 reviews and the same on the QuickBooks Marketplace across more than 120. Review counts are not a substitute for a trial, but a four-figure install base rating a bookkeeping integration that highly is a reasonable signal that the settlement mapping does not produce garbage.
How to actually decide
Work through it in this order.
- What accounting system are you on? QuickBooks Desktop or Enterprise rules both out. NetSuite, now or plausibly soon, points to A2X.
- Where do you pay tax? UK, EU or PAN-EU VAT complexity points hard at Link My Books.
- What channels do you actually sell on? Square or WooCommerce points to Link My Books. PayPal as a standalone payout stream points to A2X.
- How far back do you need to go? A two year cleanup is a Link My Books strength worth confirming against A2X’s plan-level limits.
- Do you need SKU-level inventory and cost of goods sold in the ledger? If yes, neither of these is built for it and you are shopping in a different category.
That last point deserves emphasis, because it is the most common reason sellers churn off both products. A2X and Link My Books are settlement reconciliation tools. They make your revenue, fees and refunds accurate. Neither is an inventory system, and neither will tell you the landed cost of the unit you shipped this morning. If the question keeping you up is “which SKU is actually profitable,” you need a tool built around inventory valuation, and both of these will leave you short.
Run both trials. Link My Books gives you 14 days with no card required and 90 days of settlement history to test against, which is enough real data to see whether the journal entries match what your accountant expects. A2X offers a free trial as well. Fourteen days of your own settlements is worth more than any comparison table, including this one.
