For Amazon sellers · UK · EU · US · Canada
Know who owes the tax on every order.
Aiden Commerce shows your true profit, recovers money Amazon owes you, and prepares invoices and tax returns that are correct for how marketplaces actually work — including when Amazon, not you, is liable for the VAT.

Analytics tools stop at charts. Aiden goes to the filing-shaped output: the number you put in the box, with the working shown.
True profit, reconciled
Live P&L from account to SKU to order, trued-up against Amazon settlements — fees, COGS, ad spend and refunds included, across every channel on a comparable basis.
Reimbursement recovery
Detects lost, damaged and fee-overcharged inventory Amazon owes you for, builds the evidence, and files claims through an audited approval flow.
Jurisdiction-aware tax
Every order is classified for who owes the tax — you or the marketplace — under UK & EU deemed-supplier rules, US facilitator laws, and Canadian GST/HST registration status.
Invoicing that matches policy
Per-shipment VAT invoices where you're liable, receipts where the marketplace is, credit notes on returns, gapless numbering per marketplace — aligned with Amazon's one-business-day invoice policy and Invoice Defect Rate.
Making Tax Digital
UK 9-box returns prepared from digital records, with an HMRC filing pathway (OAuth, fraud-prevention headers, declaration-gated submission) currently in sandbox.
An assistant that acts
A copilot that answers from your data and proposes actions — bid changes, claim filings, campaign pauses — that execute only through a guard-railed, human-approved action layer.
Built for every market you sell in
Marketplace tax law is not one rule — it's four regimes. Aiden encodes each one, version-stamped and maintained.
United Kingdom
Deemed-supplier rules for overseas sellers, MTD 9-box preparation, import-VAT (PVA/C79) recovery into Box 4.
European Union
OSS reporting by ship-to country, marketplace-liability detection for non-EU-established sellers.
United States
Per-state marketplace-facilitator statements plus an economic-nexus tracker for registrations you may still owe.
Canada
GST/HST preparation split by registration status, PST handling, NARF exclusion, and the CA$30k worldwide threshold watch.
Security & data protection
Built to meet Amazon's Data Protection Policy and UK/EU data-protection law from day one.
Encryption everywhere
TLS in transit; credentials and personal data encrypted at rest with authenticated encryption. Amazon refresh tokens are never exposed to the browser.
Least data, least time
We request only the API roles the feature needs, and retain buyer personal data only as long as invoicing law requires — then it's gone.
Every action audited
Anything that writes to your seller account flows through one immutable, timestamped audit log with explicit approval steps.
Your data, your exit
Export everything — orders, invoices, returns, reports — in open formats at any time. No lock-in.
How it works
Connect
Authorise Aiden with your Amazon account through Amazon's own consent flow. No passwords shared, revoke any time from Seller Central.
Classify
Orders sync and every one is classified: who owes the tax, what document it needs, which return it belongs on.
File with confidence
Invoices upload on time, returns are prepared with the working shown, and your accountant signs off on numbers that are finally right.
