Selling on more than one marketplace breaks general accounting software in a specific way. Each channel deposits a net figure that has already had a dozen fee types subtracted from it, on its own settlement calendar, with refunds and reserves mixed in. Five platforms below are built to translate that into correct entries. They are not interchangeable, and the differences between them are mostly about how much detail reaches your ledger and how much of the work they do beyond posting.
Prices cited were checked on each vendor’s own pricing page in August 2026 and move regularly. Confirm before you commit.
1. A2X
What it does: posts summarized settlement journals into QuickBooks Online, Xero or NetSuite.
A2X is the default answer for accountants because it does one thing with unusual reliability. For each settlement period it produces a single journal entry that breaks the deposit into gross sales, refunds, and each fee category, and that entry ties exactly to the amount that hits your bank. Reconciliation stops being an argument.
The pricing model is worth understanding because it is unusual. A2X charges per sales channel rather than per business. Entry plans are listed at $29 a month each for Amazon, Shopify, Etsy, eBay and PayPal, with Walmart starting higher at $79. A seller on four channels is buying four subscriptions, and the cost of a multi-channel setup adds up faster than the headline number suggests.
Best for: sellers whose accountant wants clean, auditable summary entries and who get their product-level insight somewhere else.
Limitation: summary journals by design. You will not get per-SKU revenue or COGS inside your accounting system from A2X alone.
2. Link My Books
What it does: summary settlement entries into Xero or QuickBooks, matched automatically against bank deposits.
Link My Books occupies similar ground to A2X with the broadest channel list of anything here: Amazon, Shopify, eBay, Etsy, Walmart, TikTok Shop, Square and WooCommerce. It handles VAT and GST alongside US sales tax, which makes it the more natural pick for sellers with UK or EU exposure, and it supports COGS.
Its pricing page renders through a client-side calculator that does not display reliably outside a browser session, so pull your own quote rather than trusting a figure quoted elsewhere.
Best for: sellers on an unusual channel mix, particularly anyone combining marketplaces with WooCommerce or Square, and anyone with cross-border tax to handle.
Limitation: like A2X, this is a posting layer. It is not an inventory system.
3. Webgility
What it does: syncs orders, inventory and fees into QuickBooks Online or QuickBooks Desktop.
Webgility is the answer for sellers still on QuickBooks Desktop, which remains common among businesses with heavy inventory requirements that cloud accounting handles poorly. It goes further than a posting layer by syncing inventory quantities back to channels rather than only pushing financial data one direction.
Published plans run Pro at $79 a month for 300 orders, Advanced at $149 for 800, Complete at $349 for 1,500, and Complete Enterprise at $749 for 5,000, with multi-location inventory appearing at the Enterprise tier. Note that the order allowances are tight relative to the price at the lower tiers, so model your actual monthly volume before assuming Pro covers you.
Best for: QuickBooks Desktop users and sellers who want two-way inventory sync in the same product as their accounting integration.
Limitation: order caps escalate cost quickly, and multi-location inventory sits behind the most expensive tier.
4. Finaloop
What it does: replaces the bookkeeping function rather than feeding it.
Finaloop is not a sync tool with a ledger attached, it is a real-time accounting service. The Starter plan is listed at $245 a month and includes real-time profit and loss, balance sheet and cash flow, a general ledger, automated bank reconciliation, transaction categorization against an ecommerce chart of accounts, and a monthly finance review with a dedicated account manager. Higher tiers are quote-based and scale with revenue and complexity.
Channels shown on its pricing page center on Shopify, PayPal and Stripe, so direct-to-consumer brands are the natural fit rather than marketplace-heavy sellers.
Best for: Shopify-first brands that want to stop running a bookkeeping function internally and are comparing against the cost of a firm rather than the cost of software.
Limitation: it is priced as a service, because it is one. Comparing the $245 entry point against a $29 sync tool is comparing different purchases.
5. ConnectBooks
What it does: posts marketplace activity, including per-SKU detail, into QuickBooks Online, QuickBooks Desktop Enterprise or Xero.
The distinguishing feature is depth of detail reaching the ledger. Where the summary tools post one entry per settlement, higher tiers here push transactions, fees, returns and expenses per product, with landed costs and COGS attached, so a profit and loss by SKU can be produced from the accounting system itself. It covers Amazon, Shopify, Walmart, eBay and TikTok Shop, runs on accrual accounting and uses FIFO-based inventory valuation, and its inventory layer tracks age, units in transit and multiple warehouses at the top tier. Listed plans start at $149 a month with the figure varying by order volume.
Its own documentation is candid about constraints: no open API for external use, purchase orders downloadable as PDFs but not emailable from the platform, stock tracked by warehouse rather than by bin, and forecasting that accounts for lead times but not yet seasonality. If any of those are load-bearing for you, they are worth confirming first. There is a longer walkthrough of how to evaluate options in this category that is worth reading alongside vendor pages.
Best for: multi-marketplace sellers who want product-level financials inside the accounting system rather than in a separate dashboard.
Limitation: more detail in the ledger means a larger file and a heavier setup than a summary journal approach, and the entry price is well above the posting-layer tools.
How to choose
Answer one question first: do you want product-level detail inside your accounting system, or do you want clean summary entries plus a separate operational dashboard?
If the answer is summary, look at A2X or Link My Books and spend the savings on a profit analytics tool. If the answer is detail in the ledger, look at ConnectBooks or Webgility depending on whether you are on cloud or desktop QuickBooks. If the answer is that you want to stop doing bookkeeping altogether and you are Shopify-centric, Finaloop is a different kind of purchase and should be compared against firm quotes.
Then check the arithmetic on channels. Per-channel pricing, order caps and tier thresholds move the real cost a long way from the advertised entry price, and a four-channel seller can pay three times the headline figure without noticing.
Whatever you choose, the accounting obligations underneath do not change. As IRS Publication 538 sets out, a business that keeps inventories generally uses an accrual method for purchases and sales, and the Small Business Administration’s guidance on managing business finances covers the recordkeeping baseline. Software makes compliance cheaper. It does not make it optional.
