Comparison
Looking for an A2X alternative?
A2X does one job well: it turns an Amazon settlement into an accounting entry, and on Starter and above it posts a COGS entry too. Then it hands all of that to a cloud ledger you pay for separately, and the unit costs behind the COGS come from a file you maintain. Nexus Ledger is the connector and the ledger in one book, with a perpetual inventory subledger behind the cost figure.
What each one costs, monthly
| Line | Monthly |
|---|---|
| A2X Starter — settlement connector | $59 |
| QuickBooks Online Essentials — the ledger it posts into | $85 |
| A2X + QuickBooks Online — together | $144 |
| Seller Growth — Nexus Ledger — connector and ledger in one | $59 |
Seller Growth carries the same order volume the connector leg above is quoted at (up to 1,000 Amazon orders / mo), so this is like for like: 59% less per month, and it replaces both lines rather than sitting beside them.
Priced on: 1 Amazon merchant ID, up to 1,000 orders / mo, multi-currency books. Both legs are tier-forced: Starter is the cheapest A2X plan that includes COGS, and Essentials is the multi-currency tier. A seller who bills in one currency can buy QuickBooks Simple Start ($38) instead, which lowers this column; below 200 orders a month the connector leg drops too, on a plan that does not include COGS.
Incumbent stack prices verified 2026-08-13; re-checked quarterly. These are the vendors’ own published list prices and change without notice — check them before you decide. Both cloud ledgers also run heavy introductory discounts, so a first-year invoice can be materially lower than the table; the gap this page describes is the steady-state one.
What A2X gets right
It is the tool most sellers reach for first, and for good reasons. A comparison that pretends otherwise is not worth reading.
- Settlement decomposition is its core competence and it has been doing it for years across many marketplaces and accounting packages.
- It sits neutrally between you and whichever ledger you already use, which matters if you are committed to that ledger or your accountant is.
- The summary-entry approach keeps your ledger tidy, and it reconciles to the payout your bank actually received.
Where the two genuinely differ
Not better and worse across the board — a different shape. A2X optimises for fitting into someone else’s ledger; we optimise for being the ledger.
One system, not two
The connector and the general ledger are the same software, so a settlement becomes a posted entry without crossing a boundary. There is nothing to reconcile between the tool that reads Amazon and the tool that keeps your books.
Inventory and COGS in the ledger
Weighted-average cost is maintained as a perpetual subledger, revalued as purchase costs layer in, with the monthly COGS run posting relief against it. Profit by SKU and by parent SKU is computed from those ledger balances rather than from a cost file kept alongside them.
The approval chain is part of the ledger
Every entry moves through prepare, check and approve before it posts, and nothing posts without a human action. On a team of two or more the approver and checker must each be someone other than the preparer, and on three or more all three roles separate; a sole operator posts alone and the entry carries a permanent attestation saying so. Once posted an entry is corrected by reversal, not by editing — with one documented same-day window to undo a fat-finger post before anything downstream has consumed it.
One bill instead of two
You are comparing a connector plus a ledger subscription against a single subscription that includes both. The table above is that arithmetic, at the vendors’ own published prices.
Two tools
A2X + QuickBooks Online, kept in step by you.
A2X
Reads settlements and posts a summary entry.
QuickBooks Online
Receives those entries as a separate system of record.
Your own cost file
Both connectors DO post a COGS entry — computed, by their own documentation, from unit costs you supply and keep up to date. The file of costs is the thing you maintain.
One platform
The connector and the ledger are the same system.
- Settlements post directly as balanced double-entry journal entries.
- Inventory is a perpetual subledger inside the books: purchase costs layer in on receipt, weighted-average cost is revalued as they do, and the monthly COGS run posts relief against it — so gross profit is a ledger balance, not a figure assembled from a cost file.
- VAT, FX and the approval chain run on the same entry, so there is no seam to reconcile.
Moving across
You do not rebuild your history by hand. We anchor on opening balances and rebuild forward from recent settlements, and you approve every entry before it posts.

Questions sellers ask
It includes one, but that is not the product. A connector reads your settlements and posts a summary entry into an accounting package you buy separately. Nexus is both halves: the settlements land as balanced double-entry journal entries in a full IFRS ledger that we also provide, so there is no second subscription and no reconciliation between the two.
That is the point of the comparison, but it is your call. Sellers who keep their existing ledger for reasons outside Amazon can — you would simply not be using the half of Nexus that replaces it. Sellers who switch stop paying for two tools and stop reconciling between them.
You are not asked to rebuild it by hand. We anchor on an opening trial balance exported from your current ledger and rebuild forward from recent settlements. Everything arrives as drafts and you approve them before anything posts.
It does, and the comparison should be precise about it. By A2X’s own description it multiplies the quantity sold of each SKU by a unit cost you supply, and posts that monthly — so the accuracy of the entry rests on the cost list you maintain. Nexus derives the cost instead of being told it: purchase costs layer into a perpetual inventory subledger when stock is received, weighted-average cost is revalued as they do, and the monthly COGS run posts relief against that balance. The difference is where the number comes from, not whether an entry appears.
The live demo is a synthetic walkthrough — real artefacts, invented figures, no signup and no card. For your own data, connecting Amazon is read-only: we read settlements, fees, refunds, reserves and reimbursements, never buyer personal data, and we never write to your Amazon account.
