The five QuickBooks integrations an ecommerce seller should know are A2X, Link My Books, Synder, Webgility, and ConnectBooks. Each one takes marketplace payout data and turns it into ledger entries, and each makes a different trade between price, channel coverage, and how much detail lands in QuickBooks. Intuit’s own integrations page says QuickBooks connects to more than 800 apps, and its app store carries a disclaimer that Intuit does not guarantee any third-party app’s functionality or accuracy. So the choice is yours, and the five below cover the range. Prices and features were read from each vendor’s live site in September 2026 and move with order volume.
1. A2X
A2X is the established summary-journal tool. For Amazon it lists Mini at $29 a month for 200 orders with no cost of goods sold, Starter at $59 for 1,000 orders with COGS, Standard at $79 for 5,000, and Premium tiers from $229 that allow five Amazon merchant IDs. The free trial lets you post three real settlements before paying.
What it posts: one journal entry per settlement, with sales, fees, refunds, and reserves mapped to accounts you choose. COGS, where included, is calculated per SKU per payout and posted as a single entry from inventory asset to COGS expense. What it does not do is manage inventory quantities. Multi-channel sellers use A2X Multi, priced separately.
Best for: an Amazon-first seller on QuickBooks Online who wants clean settlement journals and monthly COGS without carrying units in the ledger.
2. Link My Books
Link My Books covers Amazon, Shopify, eBay, Etsy, Walmart US, TikTok Shop US and UK, WooCommerce, and Square. On the accounting side it lists QuickBooks Online plans only, and Xero on every plan except Cashbook. Its pricing page renders as a slider by order count and channel count, so no single price is quoted here; check the page with your own volume.
What it posts: settlement-level entries with sales, refunds, fees, and taxes split out, COGS tracking, and a per-channel P&L view inside the app. The trial imports 90 days of settlements and paid plans reach back up to 24 months. Its tax wizard is built around UK and EU VAT, which is a strength for sellers with European entities and irrelevant for a US-only operation.
Best for: a seller with a wide channel mix on QuickBooks Online or Xero who wants the setup to take an afternoon.
3. Synder
Synder lists Basic at $52 a month billed yearly, or $65 monthly, Essential from $103, Pro at $240, and Pro Max at $480, with a 15-day trial. QuickBooks Desktop appears from the Essential tier up, alongside QuickBooks Online and Xero, and the pricing page also references NetSuite and Sage Intacct.
What it posts: transaction-level or summarized sync, configurable per source. Synder treats payment processors as first-class connections, so a Shopify store running PayPal and Klarna next to Shopify Payments gets each processor reconciled on its own. That is the feature that separates it from the settlement-journal tools.
Best for: a Shopify-heavy seller with several payment gateways, or a business whose ledger is something other than QuickBooks Online and Xero.
4. Webgility
Webgility runs two ladders. For QuickBooks Online and Xero: Pro at $69 a month billed annually or $79 monthly for 300 orders and two channels, Advanced at $129 or $149 for 800 orders, Complete at $299 or $349 for 1,500 orders and three channels. For QuickBooks Enterprise: Advanced at $199 or $249 for 1,000 orders, Premium at $399 or $499 for 3,000, Complete at $599 or $749 for 5,000 orders and five channels. Overage is $10 a month per 500 orders, extra channels are $20 a month, and history beyond three months is a $200 one-time fee.
What it posts: orders, returns, refunds, payouts, fees, and inventory with price and cost, bi-directionally. The Enterprise ladder adds bin and location mapping and, at Premium, Amazon FBA inventory reconciliation. The Complete tiers bundle an accountant-verified monthly close. Channels run from Shopify and WooCommerce through Amazon, Walmart, eBay, Etsy, and TikTok Shop, plus Shopify POS and Lightspeed.
Best for: a seller on QuickBooks Enterprise who needs order-level sync and wants a human close included in the price.
5. ConnectBooks
ConnectBooks lists Gold starting at $149 a month, Diamond at $199, and Platinum at $349, each for one marketplace at the starting price with the bill adjusting to order volume, and a 30-day trial. Marketplaces are Amazon, Shopify, Walmart, TikTok Shop, and eBay. Ledgers are QuickBooks Online, QuickBooks Desktop Enterprise, and Xero.
What it posts: Gold sends a summary to QuickBooks and shows net profit and COGS per SKU inside the app. Diamond syncs per-SKU data to the ledger with landed cost. Platinum adds multi-warehouse inventory, inventory age, turnover, forecasting, and automated FBA reconciliation. Valuation is FIFO, accounting is accrual, and the pricing FAQ says history goes back 18 months with six weeks free. The Amazon-to-QBO connection is documented at https://www.connectbooks.com/integrations/amazon-and-quickbooks-online. Two limits from the same FAQ: no bin or zone tracking, and no open API.
Best for: a multi-marketplace seller at real volume who wants inventory and SKU-level profit inside QuickBooks rather than in a separate tool.
How to choose between them
Start with the ledger. QuickBooks Enterprise narrows the list to the three that name it: Webgility, Synder from Essential up, and ConnectBooks. Link My Books states QuickBooks Online only, and A2X’s pages name QuickBooks Online and Xero, so confirm with A2X before assuming Desktop. QuickBooks Online keeps all five.
Then decide what the ledger needs to hold. If your accountant wants one journal per settlement and a monthly COGS figure, A2X or Link My Books is the cheapest correct answer. If you need per-order detail because you run B2B invoices with terms, Webgility’s Advanced tiers exist for that. If you need per-unit cost and stock levels in the books, ConnectBooks Diamond or Platinum, or Webgility’s Enterprise ladder, are the two that do it.
Last, count channels and gateways. Etsy sellers should note ConnectBooks does not list it. TikTok Shop sellers should note Link My Books, Webgility, and ConnectBooks list it by name. Multiple payment processors on one Shopify store points toward Synder.
What every one of them still needs from you
A chart of accounts with a separate line for each fee type, a decision on cash versus accrual that matches what your CPA files, and a monthly check that the sum of posted settlements equals the sum of bank deposits. None of the five will do that check unprompted. And at year end, the marketplace’s Form 1099-K will show gross payments, which the IRS explains on its 1099-K page can arrive even below the $20,000 and 200-transaction threshold. Gross on the form, net in the bank, and the integration you chose is what bridges the two for your accountant.
