Azentro traces every sold unit back to the exact purchase lot it came from, at that lot's real cost — freight, prep and all. Accounting-grade profit, COGS, VAT and payouts for Amazon FBA sellers.
Two cases of the same product bought at different prices are two different costs. Averaging them is where most tools quietly lose the truth — and every margin downstream inherits the error.
A figure that cannot be traced to Amazon data or a recorded purchase does not go on screen. Gaps show as gaps, and a full rebuild from source does not change the answer.
These are the ledgers Azentro is keeping right now — every sold unit costed to a purchase lot, every order reconciled against what Amazon actually booked. The figures below come straight from the engine and move as it works.
Measured throughput of the Azentro engine on a live UK seller account, February 2024 to July 2026. These are processing figures, not a customer count — Azentro is new, and no testimonials, benchmarks or awards are claimed anywhere on this site.
Buy the same product twice at two different prices and you own two different costs. Collapse them into a SKU average and every margin downstream is an estimate. Azentro allocates FIFO — each sold unit is matched to a specific purchase lot, and carries that lot's cost plus the freight and prep actually spent on it.
This is the question mainstream tools skip, and it is the one that costs real money. Azentro reconciles what you physically bought and prepped against what Amazon actually received — including bundles, multipacks, merged lots and unit discrepancies — then resolves every missing unit to reimbursement or write-off. Nothing is left unexplained.
Connect Amazon, bring in your purchases and prep costs, and let Azentro resolve every sold unit to the lot it came from.
Six parts of the product, shown as they actually look. Nothing here is an icon standing in for a feature.
Amazon UK, in GBP. Other marketplaces and currencies are not supported yet — when they are, it will be because the VAT and settlement logic has been done properly for them, not because a flag was flipped.
There is no published price yet. Azentro is early and pricing is still being worked out; when there is a price it will be published on the pricing page, and you will be told before it applies to you rather than after.
You record purchases, suppliers and prep costs in Azentro. It pulls sales, fees, shipments, returns, removals, reimbursements and settlements from Amazon's SP-API. FIFO allocation then matches each sold unit to a specific purchase lot and carries that lot's real cost.
Settlement reports can be imported by CSV as well as pulled live, so periods that pre-date your API access still reconcile instead of starting your books at zero.
Connect your Amazon UK account, bring in your purchases and prep costs, and let Azentro resolve every sold unit to the lot it came from.
