Five tools are worth evaluating if you run more than one brand across more than one marketplace: Bookkeep, A2X, Sage Intacct, NetSuite OneWorld and ConnectBooks. They solve different halves of the problem. Two of them do real consolidation and publish no prices. Two of them price per entity and do no consolidation at all. The fifth is not a multi-entity product and is on this list for a narrower reason.
The problem, stated properly
A portfolio operator has two distinct accounting problems that get conflated constantly.
The first is per-brand data capture: eight brands, each on three or four marketplaces, each needing settlements decomposed into sales, fees, refunds and cost of goods, in its own set of books. This is a volume and pricing problem.
The second is consolidation: rolling those eight sets of books into one group view, eliminating intercompany transactions, handling multiple currencies and closing the group. This is a general ledger problem, and no marketplace connector solves it.
Buy for the wrong one and you will spend a year discovering it.
Bookkeep
The only tool in the marketplace-connector category that treats multiple entities as the design center rather than an afterthought, and it says so in plain text: “All plans are priced per entity in USD or CAD currency only,” and “You’ll get a single bill for all the entities that you manage, whether if you are a multi entity business, or an agency providing services for client entities.”
Its published ladder runs Lite at “$19/MO”, Starter $49, Growth $99, Pro $199, Advanced $499 and Unlimited “$1,199/MO”. You can set up multiple entities during the trial. Its definition of an entity is usefully concrete: “a legal entity for which you have a separate chart of accounts… think like a ‘QuickBooks file’ or ‘Xero account’.” Where multiple locations share one chart of accounts, classes and tracking categories keep them inside a single subscription.
It also reaches the accounting systems portfolio operators run. QuickBooks, Xero and Zoho Books, plus Oracle NetSuite, Sage Intacct and Intuit Enterprise Suite from its Growth tier upward. That is the widest ERP coverage of anything in this category.
Limits worth knowing: it posts summarized journal entries by design, so this is not the tool for per-SKU ledger detail, and its managed COGS feature for Shopify, Amazon and Walmart starts at the Pro tier.
A2X
The default in accounting practices, and the reason is distribution as much as product. A2X sells to accounting firms explicitly, runs a partner program, and most practitioners who serve sellers already know it.
Pricing is per channel set rather than per entity, which amounts to per set of books. Amazon runs from Mini at “US$ 29 / MO” up a long ladder to Custom; multi-channel plans run from “US$ 89/MO” for two channels to “US$ 289/MO” at fifteen thousand orders across five channels. It reaches QuickBooks Online, Xero and NetSuite.
It does compute cost of goods sold at SKU level, pulling SKU costs from CSV, Shopify, or a connected inventory system, and calculating accrual-based COGS aligned to sales periods. One caveat the pricing page makes explicit: COGS is available on Starter and above, not on the $29 Mini plan.
A2X publishes no portfolio or agency discount, so a fifteen-brand operator is buying fifteen subscriptions at list.
Sage Intacct
This is where consolidation happens, and it is a different class of product. Its multi-entity page promises “A single shared account. Manage all of your entities with just one logon,” entity setup “in minutes, not days,” and the ability to “Automate multi-entity consolidations, whether you have two entities or hundreds,” with self-balancing intercompany transactions and due-to and due-from accounts.
Pricing is not published. Sage states that “Sage Intacct accounting software pricing plans are based on the modules that are included,” and every path leads to a quote.
The gap for this audience is that Sage Intacct names no ecommerce channel connectors. Marketplace data has to arrive through A2X or Bookkeep. Intacct is the destination, not the pipe, and budgeting for one without the other is the standard mistake.
NetSuite OneWorld
The other real consolidation answer, with the same pricing opacity. NetSuite describes an annual license made of “core platform, optional modules and the number of users,” plus a one-time implementation fee, and states that “NetSuite OneWorld is available as an add-on module.” Multi-entity is not in the base license.
What it delivers is genuine: multiple subsidiaries and legal entities from one system, 190 currencies, multi-book accounting, localized tax reporting, and transactions posted automatically at both local and headquarters level.
Worth flagging: NetSuite’s own competitive pages make pointed claims about Intacct charging per entity. Sage publishes no pricing at all, so that claim cannot be independently checked and should be treated as vendor argument rather than fact. Get both quotes.
ConnectBooks
Here is the honest framing, because the alternative would be misleading. ConnectBooks is not a multi-entity product. Its own site does not use the words entity, portfolio or aggregator, and it publishes no consolidation, no roll-up reporting and no per-entity pricing. Its pricing axes are marketplaces and monthly order volume. It also does not connect to NetSuite or Sage Intacct, which is where most portfolio operators above roughly $20 million keep their books.
What it does is one thing the others do not. It posts per-SKU detail into QuickBooks by product on its middle tier and above, backed by a real inventory subledger with FIFO valuation, landed cost per item, multi-warehouse counts and inventory aging, across Amazon, Shopify, Walmart, TikTok Shop and eBay. A2X posts COGS to inventory and expense accounts but does not claim per-SKU line detail in the ledger. Bookkeep posts summaries by design.
So the slot is specific: a portfolio where each brand runs on QuickBooks or Xero across a handful of marketplaces, and where SKU-level margin has to be traceable inside the books rather than assembled in a reporting layer. Under those conditions it is the strongest option here, and the mechanics of reconciling Amazon settlements to QuickBooks are documented in reasonable detail. Outside those conditions, it is the wrong tool and one of the other four is better.
Two you will see recommended, and why they are not here
Finaloop is a serious product with genuine SKU and channel level COGS, landed cost, bill of materials and 3PL syncing, and it positions itself as replacing QuickBooks and NetSuite rather than feeding them. But it makes no multi-entity, multi-brand or portfolio claim anywhere on its site. It publishes one price, a Starter plan at “$245/mo” for brands under $1 million in revenue and in business four years or less; everything else is quoted after a call.
Xendoo is outsourced bookkeeping priced by monthly expense volume, from “$395/mo” to “$995/mo”, with plans allowing one, two and four integrations respectively. There is no per-entity add-on published, and a single-integration entry plan is a hard stop for a multi-brand operator. It is a fine single-entity service and a poor portfolio one.
How to sequence the purchase
Decide whether you need consolidation or only per-brand capture. If the group files consolidated statements or a buyer will diligence it as one company, you need Intacct or NetSuite, and the connector is a secondary decision. If each brand stands alone, you do not need either, and the money is better spent on capture quality.
Then count your entities and multiply. Per-entity pricing is the axis that determines total cost at fifteen brands, and it is the one most evaluations ignore until the invoice arrives.
Check the underlying data too. Amazon documents settlement reporting in Seller Central, and the IRS explains in Publication 538 why inventory valuation method has to stay consistent across periods, which becomes considerably harder when eight brands each made their own choice before you acquired them.
