Accounting Software for Online Business: Ecommerce Accounting Software for Multi-Channel Sellers

What ecommerce accounting software has to do that ordinary accounting software does not

A plain ledger assumes money arrives as a payment against an invoice you raised. Marketplace selling does not work that way. Amazon, Shopify, eBay and Etsy collect the full amount from the buyer, subtract their commission, payment processing, advertising, refunds and reserves, and then deposit whatever is left on their own schedule. By the time the money reaches your bank it is a single net number that has lost all of its structure.

That is the whole problem in one sentence. Your bank feed says $4,182.60 landed on Tuesday. Your marketplace sold $5,411 that period, charged $712 in fees, refunded $340, and held $176 in reserve. If you book the $4,182.60 as revenue, your reported sales are understated by more than $1,200, your fee expense is zero, and nothing about the return matches what the platform will put on your 1099-K at the end of the year.

So ecommerce accounting software has three jobs a general ledger alone does not do. It has to break each deposit back into the parts it was made from. It has to tie those parts to the correct period rather than the day the cash arrived. And it has to do that across every channel you sell on, because the seller with one Shopify store is now unusual and the seller with Shopify plus Amazon plus Etsy is normal. If you want the same view across creator platforms and marketplaces at once, that is what our multi-platform income tracker is built to show.

The free connectors Intuit publishes, and the one limit they share

Intuit ships first-party connector apps for Shopify, Amazon, eBay and Etsy. Each one is included with a paid QuickBooks Online subscription rather than sold separately, and they are considerably better than most paid-connector marketing suggests. The Shopify Connector by Intuit brings across sales, refunds, Shopify Payments payouts, processing fees, sales tax broken out by jurisdiction, customers and inventory quantities, and it is recommended by both Intuit and Shopify. The Amazon Marketplace Connector by Intuit imports item-level detail and can pull up to twelve months of history the first time you connect it.

For a seller doing a couple of hundred orders a month, that is very often the whole answer. Paying a connector on top of it is money you did not need to spend, and you should try the free route first.

The limit they share is structural rather than a missing feature. All four post at the ORDER level. A payout is a settlement: a batch of orders, refunds, fees and adjustments that a platform closed out and paid together. When your books are built from orders and your bank statement is built from settlements, the two never line up on their own, and someone has to close the gap by hand every month. At low volume that reconciliation is twenty minutes. At a few thousand orders a month it is a job.

The Amazon case is the sharpest illustration. The older Amazon integration for QuickBooks worked from settlement reports, which Amazon publishes roughly every fourteen days. The current app posts order-level transactions as they happen instead. If you only want sales appearing in the ledger promptly, that is an improvement. If you reconcile, it went backwards, because settlement structure is what ties to the deposit and order structure is not.

When a paid connector like A2X or Synder is actually worth the money

The honest trigger is volume, not a feature you are missing. Roughly speaking, once you are past a few hundred orders a month on a channel, the monthly hand-reconciliation the free connector leaves behind costs more in your time than $29 does. Below that, it does not.

A2X starts at US$29 a month and is priced PER SALES CHANNEL, which is the detail that changes the math for multi-channel sellers. Shopify plus Etsy is two subscriptions, not one, and Walmart is quoted separately at $79. A2X does one thing very precisely: it turns each settlement into a single summarized journal entry, split into gross sales, fees, refunds and tax, posted to the period the settlement covers. That entry reconciles to the deposit exactly, which is the entire point. A2X was Xero's 2025 US Small Business App of the Year and rates around 4.9 out of 5 across roughly 318 G2 reviews.

Synder is a different shape. It starts at $65 a month for Basic and is metered by synced transactions, with 500 included on Basic, 1,000 on Essential, 10,000 on Pro and 20,000 on Pro Max; annual billing runs about 20% less. It earns its higher price when your money arrives through several payment processors as well as marketplaces, because it feeds Stripe, PayPal and card processors into the same ledger.

Link My Books does the same settlement-summary job as A2X, and it deserves a warning rather than a price. The vendor publishes no named tiers and no fixed prices at all: the pricing page is a calculator keyed to orders per month and channel count, and it renders in pounds. Any US dollar figure you see quoted for Link My Books in a roundup is somebody's currency conversion of a calculator result, not a published list price. Ask the vendor directly rather than trusting the table.

Reconcile to the payout date, not the order date

This is the single most common bookkeeping error in ecommerce and it is worth stating on its own. Every marketplace reporting screen defaults to filtering by transaction or order date. Every bank deposit is a settlement. A payout that lands on Thursday is paying you for orders that closed on Monday and Tuesday, so a report filtered to a calendar month will never equal the deposits that arrived in that calendar month.

The fix is the same everywhere: pick the payout or settlement date as your filter, then match deposit by deposit. Amazon settlement reports live under Reports, then Payments, then All Statements, and each one covers a single disbursement period of roughly fourteen days. Amazon keeps about three years of them. Shopify publishes a payout reconciliation report under Finance, then Documents, exportable to PDF only, with a three-day data delay and custom ranges available from January 1, 2025 onward. eBay gives a transaction report in Seller Hub that itemizes every fee and credit as CSV.

One trap specific to Amazon: date range reports are keyed to ORDER date and can only be set from January 1, 2025. If you reconcile against those instead of the settlement reports, you will chase a difference that does not exist. Our payout reconciliation page walks the process channel by channel.

What each marketplace gives you before you buy anything

None of the four marketplaces sells accounting software, and it is worth knowing exactly where each one stops so you are not paying for something you already have.

Amazon. Seller Central gives a Payments dashboard, settlement reports every disbursement period listing every order, refund, fee, adjustment and reserve as rows, date range reports, business reports, and fulfillment and inventory reports. No ledger, no chart of accounts, no bank reconciliation, no balance sheet, no profit and loss, and no visibility into anything you spend off Amazon.

Shopify. Sales reports by product, channel and month, a payouts list, the payout reconciliation report, a balance transactions export, and estimated sales tax. Cost of goods is partial and only appears if you set cost per item per variant. The balance transactions CSV is emailed to you rather than downloaded in the browser, which surprises people the first time.

eBay. Seller Hub has a Payments tab, an order report, and a transaction report that itemizes every fee and credit, all as CSV. eBay also lets the seller choose payout frequency and change it at any time: daily, weekly on Tuesdays, every other Tuesday, or monthly on the first Tuesday. That choice matters more for bookkeeping than most sellers realize, because daily payouts mean roughly twenty small deposits a month to reconcile instead of four clean batches, and switching costs nothing.

Etsy. Monthly statements and a payment account view, and no reconciliation document at all. Etsy is the thinnest of the four on the reporting side, which is why our Etsy bookkeeping software page spends most of its length on what you have to reconstruct yourself.

Sales tax, the 1099-K, and the gross versus net trap

Marketplace facilitator laws mean the marketplace usually collects and remits sales tax on your behalf for marketplace sales. That does not make the money invisible to your books. The tax collected passes through your gross figures and has to be recorded and then backed out, or your revenue will be overstated by the tax amount. Sales you make on your own Shopify storefront are a different matter entirely, because there you are the one with the collection and filing obligation.

The 1099-K is where the gross versus net problem becomes expensive. Following the One Big Beautiful Bill Act, the federal 1099-K threshold reverted to more than $20,000 AND more than 200 transactions, and both conditions have to be met. Some states set lower thresholds, and income is taxable whether or not a form is issued. The critical detail is that platforms report GROSS on the 1099-K, before their commission, before processing fees, before refunds.

So if you build a Schedule C from the net deposits in your bank account, your reported receipts will be lower than the 1099-K the IRS already has, by exactly the total of the fees you never recorded. The fees are deductible, but only if you booked them. This is the concrete reason ecommerce accounting software is not optional once you cross a marketplace threshold, and it is also the reason a bank feed on its own is not enough. Our fee breakdown shows what each platform takes before the deposit reaches you.

Choosing your stack by order volume

Here is the decision in plain terms, with no vendor preference in it.

Under about 100 orders a month, single channel. A ledger plus the free first-party connector. QuickBooks Online Simple Start at $38, or Wave at $0 if you are willing to do the marketplace side by hand. Do not buy a paid connector yet; you will not use what it does.

Roughly 100 to 500 orders a month, one or two channels. Still ledger plus free connectors, but start reconciling to settlements monthly rather than glancing at the bank balance. This is the band where people discover the order-versus-settlement gap for the first time. If the monthly cleanup is consistently eating an afternoon, that afternoon is worth more than $29.

Past 500 orders a month, or three or more channels. Add A2X per channel, or Synder if payment processors are also in the mix. At three channels A2X is roughly $87 a month, which is where Synder's single subscription starts looking better on price even though it costs more on paper.

Past roughly $1M a year, or when inventory accounting is the real problem. This is where a service like Finaloop at $245 a month or an inventory-aware system stops being an extravagance. Finaloop qualifies businesses up to $1M annual gross revenue and up to 4 years in business for its Starter plan, and it is worth being clear that it is labor rather than software you operate. Roundups that list it beside $38 software without flagging that difference are not helping you.

Whichever stack you land on, none of these tools answers the question of what each channel actually nets you month to month, which is the question most sellers are really asking when they start shopping. Our roundup of the best income tracker apps covers that side, and the per-channel pages for Amazon accounting software and Shopify accounting software go deeper on each platform.
