This is your workspace,three minutes after you connect.
Below is a fully synthetic workspace for a fictional US Amazon FBA seller — every settlement composed into a balanced double-entry, cost of goods from the unit cost you set per SKU, and you approving each settlement with one click. The numbers are illustrative. The mechanics are exactly what you get on day one.
From $29 / mo · 30-day free pilot · no credit card
A sample Amazon settlement assembling into a balanced double-entry journal: sales, fees and refunds on one side, the deposit on the other, plus a cost-of-goods relief — debits equal credits at 34,160.00.
FIG 1 — Settlement → Journal entry
Amazon settlement · Mar 1–14
Illustrative figures — the same balanced entry the product books for a real settlement.
This settlement, end to end
One deposit. Seven ledger lines. Zero spreadsheets.
The signature entry above is one real Amazon settlement decomposed into a balanced double-entry. Here is what the platform did to it — illustrative figures, the exact mechanics.
The one pipeline
From an Amazon deposit to a closed period — without leaving the platform.
A settlements connector hands you a CSV and stops. A ledger waits for you to type it in. We do the whole chain: every settlement is fetched, composed, costed, tied and queued for your approval — one platform, one audit trail, every step traceable back to the source.
Connect Amazon
Authorize the Selling Partner API read-only. Settlements, fees, refunds and reserves start streaming — no CSV exports.
Fetch the settlement
Each settlement report lands intact — every transaction type kept, nothing summarised away, idempotent on the settlement id.
Compose the journal entry
Sales, fees, refunds and the net deposit are split into one balanced double-entry against your chart of accounts — debits equal credits or it does not post.
Post the cost of goods
Cost of goods is units sold × the unit cost you set per SKU, and it posts automatically when its settlement is approved — on by default, switchable off, and it never touches the bank.
Tie the trial balance
Every posted entry rolls into a trial balance whose debits equal credits — the balance is computed from the entries on every read, so the tie is asserted, not assumed.
Approve, post & close
You approve each settlement and bank match with one click; its cost of goods posts automatically with the settlement. At month-end the period closes within ±0.01, and every posted entry stays immutable.
Each stage is a real product surface — the entry at the top of this page is the output of stages 3 and 4.
The workspace
One book of record, in your language.
Dashboard, journal entries, trial balance, inventory and reports — all illustrative for the demo seller. Connect your own account and these fill with your real settlements.

This period in your books
Demo FBA Trading Co posted 19 journal entries this period. Two marketplace settlements cleared to 42,318.66 and 7,815.30 (CA), with referral and fulfilment fees of 71,400.00 booked MTD. One thing to watch: refunds rose to 2.1% of sales, driven by SKU NX-204 — worth a listing review. No reversals, no reconciliation variances.

The proof is the product
A trial balance that ties. One click per settlement. Cost of goods follows.
These are the artifacts the product hands you — rendered from the demo seller’s illustrative figures. A trial balance whose debits equal credits, and an approval queue where each settlement waits for your one click.

What you are looking at
Connect once. Settlements become books. You stay in control.
The demo above runs the same three movements your real workspace does — only the data is synthetic.
Connect
One click, then it flows
Authorize once. Settlements, fees, refunds and reserves stream in through the official Selling Partner API — no CSV exports, no copy-paste.
- Read-only · no buyer personal data requested
- Multi-marketplace · US / CA / MX
Compute
Settlements become balanced books
Every settlement is composed into one balanced double-entry against your chart of accounts — sales, fees, refunds and reserves, each line traceable to its source.
- Cost of goods = units sold × your SKU unit cost
- CAD and MXN settlements converted at the posting-date rate
- Debits equal credits, or it does not post
Control
You approve. One click per settlement
You approve each settlement and each bank match with one click, and its cost of goods posts automatically with the settlement (on by default; you can switch it off). Every trial-balance row drills to its entry and its source document. Posted entries are immutable, and books are kept in English and Arabic.
- One click per settlement · cost of goods posts with it
- Bilingual EN + AR books
Inside the workspace
The capabilities that replace the stitched stack.
Settlements, cost of goods, and the approval-to-close chain — each one a stage your real books move through. Switch between them; every panel renders the demo seller’s illustrative figures.
Every settlement → one balanced entry
A settlement report is decomposed into sales, fees, refunds and the net deposit — split into a single double-entry against your chart of accounts. Idempotent on the settlement id, so the same payout is never booked twice.
- Pulled via the official Selling Partner API — no CSV
- Each line drills back to its settlement transaction
| Gross marketplace sales | 24,800.00 |
| Referral & selling fees | (3,200.00) |
| FBA fulfilment fees | (1,800.00) |
| Sales returns & refunds | (700.00) |
| Net deposit to clearing | 19,100.00 |
Why one platform
The stitched stack vs. the single book of record.
The usual Amazon-seller setup is a settlements connector, plus a general ledger, plus spreadsheets to reconcile the two — three tools, three exports, three places the numbers can drift. Nexus Ledger is the connector and the audit-grade ledger in one.
Bilingual by default
The same entry, in Arabic and English.
Every account carries an English and an Arabic name, and the interface switches to a right-to-left layout in Arabic. Same book, either language.

Same journal entry · both books · illustrative figures.
What connects
Official APIs in. Audit-grade books out.
No CSV scraping, no browser plug-in. Authorize the official Amazon Selling Partner API read-only, connect the live bank feed (one provider today) or upload a statement, and the rest is the platform.
Amazon Selling Partner API
Settlements, fees, refunds and reserves — read-only, no buyer personal data requested.
Multi-marketplace
US / CA / MX marketplaces under one set of books, each settlement in its own currency.
Multi-currency · daily FX
Settlements in CAD or MXN convert to your reporting currency at the entry’s posting-date rate from a daily feed.
Bank reconciliation
Connect the live bank feed (one provider today) or upload a statement (CSV or OFX) from any other bank; each line is matched to its deposit or explained.
Unit cost per SKU
Enter each SKU’s unit cost at onboarding and edit it any time; cost of goods is units sold × that cost.
English and Arabic books
Every account carries an English and an Arabic name, and the interface switches to right-to-left in Arabic.
Controls built in
Audit controls are in the schema, not a bolt-on.
Immutable posted entries, linked reversals, an append-only audit log, a period close that ties within ±0.01, and data held under a DPA — encoded from day one, on every book.
Debits equal credits, always
A database trigger rejects any entry where debits do not equal credits, so an out-of-balance entry cannot be posted. The trial balance ties to the cent.
Posted entries never change
Each posted entry is immutable; a correction is a linked reversal, shown as its own entry beside the original, never an edit.
One click, with dual control from the second user
You approve each settlement and each bank match with one click. Manual entries go prepare → check → approve. With two or more users dual control binds; a solo owner posts as sole approver and each such post writes a permanent attestation to the audit log.
11-year append-only retention
The audit log is append-only with no delete or update path; documents and entries are retained 11 years, and every trial-balance row drills to its entry and source document.
Close within ±0.01
A period closes only when the trial balance ties within ±0.01, and once closed it is locked against new entries.
EU-region storage under a DPA
Data is processed in an EU region (Stockholm) under a DPA, and customer data is never used to train any model.
Straight answers
The questions a seller-accountant actually asks.
Does it post entries to my books automatically?
Cost of goods posts automatically when its settlement is approved and posted — on by default for a new book, and you can switch it off. It never touches the bank. You approve each settlement and each bank match with one click, and manual entries go prepare → check → approve. With two or more users dual control binds; a solo owner posts as sole approver, and each such post writes a permanent attestation to the audit log. A posted entry is immutable; corrections are made by a linked reversal, never an edit.
What access does connecting Amazon give you?
Read-only access to your settlements, fees, refunds and reserves via the official Selling Partner API. We never request buyer personal data, and we never write to your Amazon account.
How is cost of goods calculated?
Cost of goods is units sold × the unit cost you set per SKU. You enter each unit cost at onboarding and can edit it later, and the cost of goods for a settlement posts automatically with it unless you switch that off.
Can I reconcile my bank?
Yes. Connect the live bank feed (one provider today), or upload a statement (CSV or OFX) from any other bank. Each statement line is matched to its deposit or explained, with one click per bank match.
Will the trial balance actually tie?
Always. A database trigger rejects any entry where debits do not equal credits, so an out-of-balance entry cannot be posted. The trial balance refreshes from posted entries and the tie is asserted, not assumed.
Is the demo data real?
No — every figure on this page is illustrative, fabricated for the fictional "Demo FBA Trading Co" and balanced to the cent. When you connect your own account, the same surfaces fill with your real settlements.
Like what you see? Make it your own books.
The workspace above is synthetic. Connect your Amazon account (read-only) and the live bank feed (one provider today) or a bank statement, and we onboard you with your own real books — the first 30 days are free and hands-on, on the plan you pick and within that plan’s limits.
