Everything Azentro does, and what each part is for.

Seven areas, one engine. Costing resolves every sold unit to a purchase lot; reconciliation makes sure the units Amazon booked match the ones you sent; the books fall out of both. Nothing on this page is a roadmap item.

FIFO costing, down to the lot

Each sold unit is matched to a specific purchase lot and carries that lot's cost — not a running average across everything you ever bought. Buy the same product twice at two prices and Azentro keeps both.

  • FIFO allocation across every sold, returned, removed and written-off unit
  • Per-unit COGS that resolves to a named purchase order
  • Prep-centre billing apportioned back over the units it was spent on
  • Inbound freight apportioned per unit, per shipment
  • Deterministic: a full rebuild from source does not change the answer

Reconciliation that resolves every unit

What you physically bought and prepped, matched against what Amazon actually received. This is the part most tools leave to you and a spreadsheet, and it is where the money goes missing.

  • Warehouse lots matched to inbound shipment lines
  • Bundles, multipacks and merged lots as first-class modes
  • Unit discrepancies raised, tracked and resolved
  • Short units resolved to reimbursement or write-off — nothing left unexplained
  • Re-inbounded removals costed back into stock at their original lot cost

Shipment reconciled — every unit accounted for

A P&L your accountant can check

Because COGS resolves to real lots rather than an estimate, every line on the profit statement traces back to a purchase, a fee or a settlement you can open.

  • Profit & loss on a net basis, Amazon-only scope
  • Payouts reconciled against the settlement lines behind them
  • Expenses and other income
  • Per-unit lot journey timeline — the full history of one unit on one page

UK VAT, done properly

Output VAT on sales, reclaimable input VAT on Amazon's fees, and a threshold watch that knows your effective registration date rather than guessing from a flag.

  • Output VAT derived from the raw settlement data, not re-computed from a rate
  • Fee VAT taken from what Amazon actually invoiced
  • Costs held net where the reclaim rule says net
  • Rolling-12-month threshold monitoring with an alert before you cross it

Reimbursements matched, not guessed

Amazon's reimbursements arrive as their own ledger, in their own time, against their own identifiers. Azentro matches them back to the units and shipments they belong to.

  • Reimbursements matched by reimbursement ID to the case they settle
  • Reimbursed units re-costed so profit is not double-counted
  • Reversals handled, including relabelled and merged listings
  • What is still outstanding, listed as work rather than buried in a report

Stock you actually own

Warehouse stock, Amazon stock and everything in transit between them, counted once and valued at what it cost you.

  • Warehouse and Amazon stock as one position
  • Inventory value at real lot cost, with capital tied up by age
  • Days of cover per ASIN, from throughput rather than a flat average
  • Stranded and unfulfillable stock surfaced as it happens
One SKU, three costs
Stock is valued at what each lot actually cost, so inventory value moves when your buying does.

Built to stay correct

The engine re-derives financial state from source on a schedule and on demand. If a figure cannot be traced, it shows as a gap rather than a plausible number.

  • Row-level security in the database, not just in the app
  • Nightly rebuild plus incremental re-costing as data arrives
  • Integrity checks that raise an alert when something does not tie
  • CSV import for suppliers, purchase orders and settlement history

Your real cost is spread across five systems.

Amazon knows what it sold and what it charged you. It does not know what you paid your supplier, what your prep centre billed, or what is sitting in your warehouse. Azentro pulls all of it into one ledger — and every figure stays traceable back to its source.

Amazon SP-API
Sales, fees, settlements, inbound shipments, returns, removals, reimbursements, inventory, account health.
Suppliers & purchase orders
The cost of goods that never touches Amazon — where a unit's real price actually lives.
Prep centres
Prep and labelling billed per unit, apportioned back to the lot it was spent on.
Physical warehouse stock
Bought, owned, not yet at Amazon. Counted as stock you hold, not stock you lost.
Settlement reports
Imported by CSV as well as pulled live, so history that pre-dates API access still reconciles.

The whole list, on one screen.
