Taxomate vs A2X vs ConnectBooks: Budget, Mid-Tier, and Full-Stack Compared
Taxomate is the right pick if you want the cheapest way to get Amazon settlements posted to QuickBooks Online or Xero and you are fine with summary entries. A2X is the mid-tier: more history, more merchant IDs, cost of goods sold posted per SKU per payout, and a price ladder that tracks order volume. ConnectBooks costs the most of the three and earns that price only if you need inventory, landed cost, and profit per SKU carried inside the ledger, including QuickBooks Desktop Enterprise, which neither of the other two supports.
Every price and feature below was read from the three vendors’ live pricing pages in September 2026. Pricing on all three moves with order volume, so treat the figures as the entry point on each ladder.
What the three tools have in common
All three read the marketplace’s own settlement data instead of your bank feed. That matters because the deposit that lands in your account is net of referral fees, FBA fees, refunds, and a reserve. Amazon’s settlement report documentation shows those amounts as dozens of rows per settlement, each with its own amount type. Post the deposit as revenue and your gross sales, your fees, and your margin are all wrong by the same number.
All three also push accrual-style entries. The IRS is explicit in Publication 538 that a business which must account for inventory has to use an accrual method for purchases and sales, with a small business exception tied to average gross receipts. A seller doing marketplace volume at scale is usually past the point where cash-basis books are defensible.
Where they part ways is depth: how much detail lands in the ledger, which ledgers they support, and how much of the inventory problem they take on.
Taxomate: the budget tier
Taxomate’s pricing page starts at $12 a month billed annually, which works out to $144 a year, at its lowest order tier. The Starter plan covers one sales channel with unlimited marketplaces under it, so one Amazon merchant ID with US, Canada, and Mexico counts as one channel. The Multi-channel plan lifts the channel cap. A third plan adds QuickBooks Online inventory sync, which Taxomate describes as still in beta and which requires QBO Plus or Advanced.
Channels are Amazon, eBay, Shopify, Walmart, and Etsy. Ledgers are QuickBooks Online, Xero, and Wave. Taxomate states on its own FAQ that it does not support QuickBooks Desktop, and that it does not sync inventory to Xero. Historical data is unlimited, which is a real advantage if you are cleaning up two years of unposted settlements. Every plan includes a free onboarding call and a 14-day trial.
Who it fits: a seller with one or two channels, on QBO or Xero, who wants sales, fees, and taxes posted as a summary journal per settlement, and whose accountant handles COGS separately or is content with a total COGS figure.
A2X: the mid-tier
A2X for Amazon lists Mini at $29 a month for up to 200 orders, one merchant ID, and three months of history. Mini does not include cost of goods sold or FBA inventory locations. Starter at $59 covers 1,000 orders with 12 months of history and turns COGS on. Standard at $79 handles 5,000 orders with 24 months of history. From Standard 10k at $159 the plans include the maximum history Amazon makes available, and the Premium tiers from $229 at 15,000 orders add five merchant IDs, running up to $1,499 at 250,000 orders.
A2X’s COGS feature calculates cost of goods sold per SKU per payout and posts one entry that moves the total from your inventory asset account to your COGS expense account. That gives you accurate gross profit in the ledger without carrying every unit in QuickBooks. It does not manage the inventory itself. If you want to sell on Shopify or Walmart too, A2X routes that through its A2X Multi product with separate pricing.
A2X wins on the free trial structure: full features, and you can post three real settlements before you pay. It also wins on history depth at the Standard tier and above, and on the number of merchant IDs at Premium. For a seller with separate North America and Europe Amazon accounts, that five-ID allowance is the deciding line.
ConnectBooks: the full stack
ConnectBooks lists Gold starting at $149 a month, Diamond at $199, and Platinum at $349, each covering one marketplace at the starting price with the bill adjusting to monthly order volume. Gold sends summary data to QuickBooks or Xero and shows net profit and COGS per SKU inside ConnectBooks. Diamond syncs per-SKU data to the ledger with landed cost per item. Platinum adds multi-warehouse tracking, inventory age, turnover, forecasting, and automated FBA reconciliation.
The marketplaces are Amazon, Shopify, Walmart, TikTok Shop, and eBay. The ledgers are QuickBooks Online, QuickBooks Desktop Enterprise, and Xero. ConnectBooks uses accrual accounting and FIFO valuation, and its pricing FAQ says it can pull up to 18 months of history, with the six weeks before signup free and older data quoted separately. Trial is 30 days.
Two limits from the same FAQ are worth knowing before you buy. Stock is tracked by warehouse, not by bin or zone. And there is no open API for external use, so a seller with a custom data stack cannot pull ConnectBooks data through code.
The decision framework
Run these four questions in order. Stop at the first one that eliminates a tool.
1. Which ledger do you run?
QuickBooks Desktop Enterprise removes Taxomate outright, by Taxomate’s own FAQ. A2X’s Amazon pricing page names QuickBooks and Xero as its targets without specifying Desktop, so confirm with A2X before assuming Enterprise is covered. ConnectBooks lists Desktop Enterprise by name. Wave removes everything but Taxomate. QBO or Xero keeps all three in play.
2. Do you need inventory in the ledger, or only COGS?
If your accountant wants a monthly COGS entry and nothing more, Taxomate on any plan or A2X from Starter up does the job. If you need inventory quantities, landed cost, and per-SKU margin living in QuickBooks, only ConnectBooks Diamond or Platinum does that among these three, and Taxomate’s QBO inventory sync is a beta with a QBO Plus requirement.
3. How many marketplaces, and which ones?
Etsy: Taxomate yes, A2X through A2X Multi, ConnectBooks no. TikTok Shop: ConnectBooks yes, A2X via its Shopify integration only, Taxomate does not list it. Walmart and eBay: all three. Multiple Amazon regions: A2X Premium’s five merchant IDs is the most generous allowance on a single plan.
4. What is your order volume, and what does that cost?
A worked example. A seller doing 4,000 Amazon orders a month on QuickBooks Online, wanting COGS but not inventory: Taxomate prices by order volume on a slider and starts far below the other two; A2X Standard is $79 with 24 months of history; ConnectBooks Gold starts at $149 and covers up to 10,000 orders before the bill moves. For that seller, A2X is the sensible middle and Taxomate the sensible floor. Swap in per-SKU landed cost and a second warehouse and the cheapest tool that does the job is ConnectBooks Platinum at $349, because the other two do not do it at any price.
What none of them replace
All three post what the marketplace reports. None of them tell you whether your sales tax nexus has changed, whether your 1099-K will match your books, or whether your reserve balance is growing. The IRS page on Form 1099-K is clear that marketplaces report gross payments and that you must report all income whether or not a form arrives. Your bookkeeper still has to reconcile the 1099-K to the settlements, and the tool you pick is only as good as the account mapping you set up in the first week.
Pick the cheapest tool that carries the detail your accountant needs. Buying ConnectBooks to post summary journals is overspending. Buying Taxomate and then rebuilding inventory in spreadsheets is the more expensive mistake.
