Three jobs. One platform.
Most sellers shortlist a settlement connector, a cloud ledger, or a profit dashboard. Each does one job. Nexus is the Amazon connector, the double-entry ledger, the bank reconciliation and the monthly close in one subscription — built for Amazon sellers in the US, Canada and Mexico. This page is an honest map of what each tool optimises for, so you can decide whether all-in-one fits you.
An Amazon settlement assembles into a balanced double-entry journal entry: sales, fees, refunds and cost of goods sold at the unit cost you set per SKU, with debits equal to credits. The settlement stays in draft until you approve it with one click.
FIG 1 — One Amazon settlement → one balanced entry
Amazon settlement · Mar 1–14
- One-click, read-only Amazon connection
- Settlements → balanced journal entries
- One live bank feed, or statement upload
- Payout matched to the bank deposit
- Cost of goods from your SKU unit costs
- One-click approval · cost of goods follows the sale
- Month-end close that has to tie
- Account names in English and Arabic
- 11-year audit retention
The loop
One engine runs the whole loop, connect to close.
A connector stops at moving settlement data. A dashboard estimates profit. A general ledger keeps generic books. Nexus runs every step between connecting your Amazon account and closing the month — each step feeds the next, with no hand-off to a second tool.
- 01
Connect
Connect Amazon in one click
One click through the official Selling Partner API, with finance access only and read-only. Each settlement comes across in full — sales, refunds, referral and FBA fees, reimbursements, reserves — instead of one lump-sum deposit you unpick by hand. No buyer personal data.
- 02
Compose
Each settlement becomes records and a journal entry
Every settlement becomes sales, refunds and fees records, composed into one double-entry journal entry. A database trigger refuses any entry where debits ≠ credits, so an unbalanced settlement can never post.
Debits = Credits · enforced by trigger
- 03
Reconcile
Match the payout to the bank
Use the live bank feed (one provider today), or upload a CSV or OFX statement from any other bank. The Amazon payout is matched to the deposit that actually landed, and you approve the settlement and its bank match with one click.
Payout ↔ bank deposit
- 04
Other costs
Add the costs Amazon never sees
Expenses that are not on a settlement — software, freight, a contractor — go in as manual journal entries with the supporting PDF attached. They post when you approve them.
- 05
Cost of goods
Your SKU unit costs drive cost of goods
You set a unit cost per SKU at onboarding and can change it any time. Cost of goods is units sold × that cost, and it posts automatically the moment its settlement sale is posted — on by default for a new book, switchable off in settings, and it never touches a bank account.
COGS = units sold × SKU unit cost
- 06
Close
Close the month
Posted entries roll into a trial balance computed live, and the month closes only when it balances within ±0.01. Closed periods refuse new entries without an adjustment flag, posted entries are immutable, and corrections are linked reversals. Every row drills to its journal entry and on to the settlement, bank line or document behind it.
TB ties · row → entry → source
The three jobs
A connector covers one. Nexus covers all three.
A settlement connector moves Amazon data into a ledger. The ledger keeps the books. Reconciling the payout to the bank and closing the month is a third job someone still has to do. Nexus is one subscription for all three.
Connect
Pull every settlement, in one click
A one-click, read-only Amazon connection with finance access only brings each settlement across in full — sales, refunds, fees, reimbursements and reserves — instead of one lump-sum deposit you unpick by hand.
- Amazon US, Canada and Mexico · more coming soon
- Every line traceable to its settlement
Book
Keep the books, cost of goods included
Each settlement becomes a double-entry journal entry that balances to the cent. Cost of goods is units sold × the unit cost you set per SKU, and it posts automatically when its sale is posted.
- Debits equal credits, enforced
- Cost of goods from your SKU unit costs
Close
Reconcile the bank and close the month
You approve every settlement and bank match with one click; its cost of goods follows automatically when you post the sale. With two or more users dual control binds automatically, and the month closes only when the trial balance ties.
- Payout matched to the bank deposit
- Append-only audit trail, 11-year retention
What it replaces
Two tools and the seam between them — or one platform.
The usual Amazon-seller setup pairs a settlement connector with a separate cloud ledger. You pay for both, and you reconcile across the seam between them. Nexus collapses the stack into one book of record.
| Stack | Connector | Ledger | Total / mo |
|---|---|---|---|
| Link My Books + Xero | $41–$47 | $90 | ≈ $131–$137 |
| A2X + QuickBooks Online | $59 | $85 | $144 |
| Nexus Ledger (Growth → Pro) | — | — | $59–$99 |
connector, ledger, bank reconciliation and close in one subscription
Replace $131–$144/mo of A2X/Link My Books + Xero/QuickBooks with $59–$99 — and get a perpetual inventory subledger behind your COGS, not a cost file you maintain. (Stack prices verified 2026-08-13.)
24–59% below the mid-band stack above, derived from these same figures · Incumbent stack prices verified 2026-08-13; re-checked quarterly.
Link My Books raised prices on 1 July 2026 and withdrew annual billing for new customers; $41 is the legacy rate the published band was built on, $47 is the vendor’s own current quote for one store at 1,000 orders/mo.
The stitched stack
Two subscriptions, two logins, and a reconciliation seam between them.
A settlement connector
Posts payouts — but is not your ledger.
A general cloud ledger
Keeps the books, matches the bank and closes the month on entries another tool posted.
One platform
One subscription, one login, one book of record — no seam to reconcile.
- The Amazon connector, the ledger, bank reconciliation and the monthly close in one subscription
- Cost of goods from the same kind of per-SKU unit cost a connector uses — posted inside the books, automatically with each sale
- The payout matched to its bank deposit on the same entries the settlement composed
- One-click approval, dual control from the second user, account names in English and Arabic
Category by category
Where each tool fits — and where all-in-one fits better
We respect every tool here. The honest framing is what each optimises for, and which seller that fits — not a scoreboard. Pick a category to see the trade-off.
A2X
The established Amazon-to-ledger settlement connector.
What it does well
- Accurate, trusted settlement-to-ledger postings.
- Broad marketplace and sales-channel coverage.
- Clean accrual summaries your accountant already understands.
Where it fits best
Sellers who already run a cloud ledger with an accountant and only need clean settlement postings into those existing books.
Where all-in-one fits better
Sellers who want the connector AND the books AND the bank reconciliation and monthly close in one subscription. Cost of goods works the same basic way — units sold × a per-SKU unit cost you set — but it posts inside the ledger it belongs to, so there is no second subscription and no seam to reconcile.
The proof is the product
What all-in-one actually puts on screen
Not a feature checklist — two real artefacts: a trial balance whose debits tie to credits, and the approval queue where each settlement and bank match takes one click while cost of goods follows the sale on its own.

Controls
Controls that hold up when someone asks
These describe how the product is built — they are not certifications, and you remain responsible for your own filings.
Balance
Debits equal credits, enforced
A database trigger rejects any journal entry where debits and credits differ. An entry that cannot balance is refused, not posted.
Immutable
Posted means posted
A posted entry is never edited. Corrections are reversals linked to the original, with one narrow same-day undo within 24 hours, before anything downstream has used the entry.
Approval
Dual control from the second user
With two or more users, dual control binds automatically — the checker cannot be the preparer. A solo owner posts as sole approver, and each such post writes a permanent attestation to the audit log.
Close
A close that has to tie
The month closes only when the trial balance balances within ±0.01 of your base currency. A closed period refuses new entries unless they are flagged as adjustments.
Audit log
11-year append-only audit trail
Every state change is logged append-only and kept for 11 years, and every trial-balance row drills to its journal entry and on to its source.
Hosting
EU-hosted under a DPA
Your books are hosted in an EU region under a data processing agreement.
What it reads
Two connections, plus your own documents
Nexus reads the two places a seller’s money actually moves — Amazon and your bank — and you add everything else as a manual entry with the document attached. Every figure drills back to its source.
Marketplace
Amazon Selling Partner API
One click, finance access only, read-only: settlements with their sales, refunds, referral and FBA fees, reimbursements and reserves. Amazon US, Canada and Mexico today; other marketplaces coming soon.
Advertising
Ad spend, from the settlement
PPC billed on a settlement is booked as operating expense, kept separate from cost of goods so margin stays honest. No separate Ads connection to authorise.
Bank
Your bank
Use the live bank feed (one provider today), or upload a CSV or OFX statement from any other bank. Each Amazon payout is matched to the deposit it became.
Other costs
Manual entries, document attached
Expenses that never appear on a settlement go in as manual journal entries with the supporting PDF attached, and post when you approve them.
Before you buy
The traps we see most when sellers compare
Buying the wrong stack is expensive — and independent of which vendor a seller eventually picks. These are the questions to ask before you commit.
- 01
A connector is not your books.
A settlement connector posts your payouts into a ledger — it does not act as the ledger. You still pay for the ledger, and you still reconcile the bank and close the month there. Nexus is the connector, the ledger, the bank reconciliation and the close in one — one subscription, one login.
- 02
A profit dashboard is not double-entry books.
Dashboards estimate profit well, but a bank, an auditor or a tax authority wants double-entry books that balance and a month that closes. A dashboard is not that. Nexus gives you balanced, drillable books with a real month-end close.
- 03
A generic ledger treats a payout as a mystery deposit.
Without Amazon-native logic, a settlement lands as one lump-sum deposit with sales, fees, refunds and reserves blended together. Reconstructing them by hand is where the spreadsheet begins. Nexus decomposes every settlement into a balanced entry automatically, each line traceable to source.
- 04
An unmatched payout is an unexplained gap.
An Amazon payout is net of fees, refunds and reserves, so it never equals the sales you booked. Until the settlement entry and the bank deposit are matched, the difference sits unexplained. Nexus matches each payout to its deposit — through the live bank feed (one provider today) or a statement from any other bank — and you approve the match with one click.
- 05
Automation without controls is a liability.
Nexus automates exactly one post — cost of goods, the moment its sale is posted (on by default for a new book, and you can switch it off). Settlements and bank matches take your one-click approval, manual entries post when you approve them, and from the second user dual control binds automatically.
English and Arabic
Account names in both languages
Every account carries an English and an Arabic name, so the same balanced entry reads in both languages. Journal narratives are bilingual on the entries our templates compose. Flip it and watch.

- No long-term lock-in · export your data anytime
No. Nexus is the double-entry ledger, not just a feed into one. Settlements, fees, refunds, cost of goods, the bank reconciliation, the trial balance and the month-end close all live in the same book of record — so the connector-plus-ledger pairing becomes one subscription.
A connector reads your Amazon payouts and posts them into a ledger you pay for separately; A2X also posts cost of goods by multiplying the quantity sold of each SKU by a cost price you supply. Nexus computes cost of goods the same basic way — units sold × the unit cost you set per SKU — but it is also the ledger, the bank reconciliation and the monthly close, so there is no second subscription and no seam between tools.
One thing: cost of goods posts automatically the moment its settlement sale is posted — on by default for a new book, switchable off in settings — and it touches no bank account. You approve each settlement and its bank match with one click, and manual entries post when you approve them. From the second user, dual control binds automatically (the checker cannot be the preparer); a one-person workspace posts as sole approver and every such post writes a permanent attestation to the audit log.
With the unit cost you set for each SKU. You enter it at onboarding and can change it any time; cost of goods is the units sold on each settlement × that unit cost. It is the same basic method a connector uses — the difference is that the entry lands in the ledger it belongs to and ties to the trial balance.
Amazon US, Canada and Mexico today; other marketplaces are coming soon. For the bank, use the live bank feed (one provider today) or upload a CSV or OFX statement from any other bank — the Amazon payout is matched to the deposit either way.
Every trial-balance row drills to its journal entry, then to its source — the settlement, the bank line or the attached document. Posted entries are immutable; corrections are reversals linked to the original; the audit log is append-only with 11-year retention.
