The 5 Best E-Commerce Integration Apps for QuickBooks Online
If you sell online and use QuickBooks Online, the integration app sitting between your sales channels and your books is the most important tool in your finance stack. Get it right and your books reconcile to the cent every month. Get it wrong and you spend hours chasing a bank feed that never quite matches your Shopify or Amazon deposits.
The reason is simple: a marketplace payout is not a sale. It is a bundle of gross sales, refunds, shipping income, marketplace fees, advertising costs, gift card redemptions and sales tax collected across a dozen jurisdictions — all netted down to one number that lands in your account days or weeks later. A good integration app unpicks that bundle into a journal entry that matches the deposit exactly. A poor one dumps thousands of individual orders into QuickBooks and leaves you to sort out the rest.
Below are the five apps we recommend most often to e-commerce clients, judged on the three things that actually matter day to day: how easy they are to live with, what they cost, and whether the numbers they produce stand up to scrutiny.
1. A2X — the accountant's default
A2X is the app most bookkeepers reach for first, and for good reason. Rather than importing every order, it creates a summarized journal entry for each payout — split by sales, refunds, fees and tax — that matches the deposit in your bank feed exactly. Reconciliation becomes a one-click job, and your QuickBooks file stays fast.
Ease of use
Middling. Setup is guided and well documented, but you map your own accounts and tax rates, and the first configuration rewards someone who understands double entry. Once it is running, it is close to invisible.
Price
From $29/month for up to 200 Shopify orders, $45 for 500 and $79 for 2,000. Premium plans start at $115. Pricing is per sales channel, so a multi-channel seller pays more than the headline suggests.
Accuracy
The benchmark. Payout-level reconciliation, proper accrual treatment, cost of goods sold support and clean handling of gift cards. If the numbers come out wrong, it is almost always the account mapping rather than the app.
2. Link My Books — the friendliest setup
Link My Books does the same core job as A2X, and its tax engine is the standout feature. It separates taxable from non-taxable sales automatically and — crucially for anyone selling on Amazon, eBay, Etsy or Walmart — correctly identifies sales tax the marketplace already collected and remitted under facilitator laws, so you are not recording a liability you never owed.
Ease of use
The easiest of the five. A genuinely good setup wizard, sensible defaults, and a free onboarding call with a human being — worth more than any feature list when you are connecting your first channel.
Price
Usage-based, calculated from your monthly order volume and number of sales channels. Entry-level plans sit in the region of $20 to $40/month. Prices rose in July 2026, so run the calculator on their site for a current quote.
Accuracy
Excellent, and arguably the best of the group on marketplace-collected sales tax specifically. Summarized entries reconcile to payouts in the same way A2X does.
3. Dext Commerce — best value, and familiar
Dext Commerce (built on the former Greenback platform) pulls itemized sales data from over 30 channels and payment processors, applies the right tax treatment line by line, then publishes daily or per-payout summaries into QuickBooks. If your bookkeeper already runs on Dext for bills and receipts, the sales side slots in neatly alongside it.
Ease of use
Easy, especially for existing Dext users. Connecting channels takes minutes and the review screen is clear.
Price
The cheapest way in: $19/month for 200 sales transactions, $59/month for 1,000, with extra bundles of 1,000 at $15. Pricing through Dext's partner program differs, so ask your bookkeeper before subscribing directly.
Accuracy
Very good. Line-level tax detail on every transaction is a real strength if you have nexus in multiple states and need to substantiate a filing. It is slightly less opinionated than A2X about accrual treatment, so review the mappings before you go live.
4. Synder — the multi-channel workhorse
Synder connects to more than 30 platforms and payment gateways, and can run in either summary or per-transaction mode. That flexibility is its appeal: if you sell through Shopify, Stripe, PayPal and a marketplace or two, Synder will pull the lot into one place and reconcile across them.
Ease of use
Moderate. There are a lot of settings, and per-transaction mode can flood a QuickBooks file if you leave it on for a high-volume store. Budget an hour or two for a careful setup.
Price
$65/month for 500 transactions, or $52/month billed annually. Essential is from $115 ($92 annually) for 1,000 transactions and Pro from $275 ($220 annually) for 10,000. Synder has flagged a price increase effective September 1, 2026.
Accuracy
Good, but more dependent on you than the others. Configured well it is reliable; configured in a hurry it produces duplicates. Duplicate prevention only appears from the Essential plan up.
5. Webgility — when inventory matters
Webgility is the heavyweight. Alongside sales and payout sync it handles inventory, pricing and cost of goods sold across channels, and it is one of the few options that also supports QuickBooks Desktop. For a seller running real inventory across Amazon, Shopify and a brick-and-mortar store, that breadth justifies the price.
Ease of use
The most demanding of the five. More moving parts, more decisions, and an implementation best done with their support team rather than alone.
Price
$79/month for 300 orders ($69 billed annually), $149 for 800 and $349 for 1,500. Extra sales channels are $20/month each and historical migration is a $200 one-time fee.
Accuracy
Very good, and the inventory and COGS sync means gross margin in QuickBooks reflects reality rather than an estimate. The higher plans include a reconciliation guarantee.
At a glance
| App | Ease of use | Price (from) | Accuracy |
|---|---|---|---|
| A2X | Moderate — guided setup, but you map accounts yourself | $29/mo (200 orders); $79/mo for 2,000 | Excellent — summarized, payout-matched journals |
| Link My Books | Easy — setup wizard plus a free onboarding call | Usage-based; entry plans around $20–40/mo | Excellent — strongest on marketplace sales tax |
| Dext Commerce | Easy — familiar if you already use Dext | $19/mo (200 transactions); $59/mo for 1,000 | Very good — line-level tax on every sale |
| Synder | Moderate — powerful, lots of settings | $65/mo, or $52/mo billed annually (500 txns) | Good — depends how you configure it |
| Webgility | Harder — the most to configure | $79/mo (300 orders); $149/mo for 800 | Very good — plus inventory and COGS sync |

None of these file your sales tax returns. They classify and record what was collected — which is exactly what your books need — but they do not calculate economic nexus or submit returns. If you have crossed thresholds in several states, you still need a filing service such as Avalara or TaxJar alongside your integration app, and the two need to agree with each other.
So which one should you choose?
There is no single winner, but there is usually an obvious answer once you know the business:
- A single Shopify or Amazon store, and you want it right first time — A2X.
- Marketplace sales tax and multi-state nexus are the headache — Link My Books.
- A smaller seller watching costs, or already using Dext for bills — Dext Commerce.
- Lots of channels and payment processors to pull together — Synder.
- Real inventory, real cost of goods sold, or QuickBooks Desktop — Webgility.
Two things matter more than which app you pick. First, set up your chart of accounts and tax mappings properly before you turn on automatic posting — every one of these tools is only as accurate as the mapping behind it. Second, run a parallel month and reconcile it by hand before you trust the automation. An hour spent there saves a day of unpicking later.
A short setup checklist
- Pick a start date and stick to it — ideally the first day of a quarter, so prior periods stay untouched.
- Build the accounts first: separate income accounts by channel, an expense account for marketplace fees, a clearing account for each payout processor, and a sales tax payable account.
- Add a clearing account per channel. Sales post in, payouts clear out, and the balance should be the money in transit at month end. If it is anything else, something is mismapped.
- Decide summary vs. per-transaction before you sync. For most sellers, summary is the right answer.
- Reconcile the first month manually against a marketplace settlement report before you enable auto-posting.
- Check gift cards and refunds specifically — they are where most misstatements hide.
