Solutions · 1P Vendor Central

One OMS for Amazon Vendor Central.

Amazon raises the PO - Finnoto's OMS runs every step after it, with no manual touches. POs validated, invoices and e-way bills generated, 3PL and GRN handled, and invoices posted the moment goods land - so you're paid faster, and never lose a deduction you don't owe.

The 1P model

You supply Amazon - you don't sell on it

In Vendor Central, Amazon is the buyer. Three things follow from that, and they shape everything.

01
Amazon raises the PO

You don't list or price products. Amazon sends purchase orders on its schedule, with strict confirmation windows and EDI/ASN rules.

02
Amazon receives & counts

Stock goes into Amazon's fulfilment centres. The GRN - what Amazon says it received - decides what you actually get paid for.

03
Amazon pays - minus deductions

Shortages, chargebacks, price and co-op claims come straight off your invoice, often wrongly, and the clock to dispute them is short.

That's why your order system has to speak Amazon's language. Finnoto is that OMS - the layer between Amazon and your books.

The Problem

A manual grind - and a leaky one

Margin leaks are only half the story. The other half is the hours your team burns keeping Amazon happy - confirming POs, chasing ASNs, posting invoices, reconciling GRNs - all against the clock.

PO ops & tight windows

POs must be confirmed within strict windows or you eat penalties - done manually across spreadsheets and the AVC portal.

Shortage claims

Amazon claims it received fewer units than you shipped and deducts the difference - frequently in error, on proof-of-delivery you already have.

ASN & routing chargebacks

Carton-level ASN mismatches, late confirmations, prep and routing errors trigger chargebacks that quietly stack up against every invoice.

Price & co-op deductions

Price claims, co-op accruals, damage and returns allowances are near-impossible to track against contract terms by hand.

GST e-invoice & e-way bill

Every invoice has to be IRP-registered and carry a valid e-way bill - get it wrong and goods are held in transit and ITC is disallowed.

GRN reconciliation

Reconciling PO ↔ ASN ↔ invoice ↔ GRN to find what Amazon actually received - and what it under-counted - is slow, manual and late.

One PO · end to end

Finnoto OMS orchestrates the whole PO lifecycle

Amazon raises the PO and pays - Finnoto runs every step in between, in one place. Follow it clockwise, from PO to payment.

Finnoto sits between Amazon and your 3PL, automating each step - so no one on your team logs into Vendor Central. On a rate mismatch, the invoice is held and Amazon looped in before proceeding.

What Finnoto automates

The whole 1P lifecycle, on autopilot

PO ingestion & confirmation

POs fetched from AVC in real time and confirmed inside Amazon's windows - no missed acknowledgements, no penalties.

Automated validation engine

Rate, inventory and GST checks on every line before anything is booked - rate mismatches flagged and routed to Amazon automatically.

Invoice, e-invoice & e-way bill

Invoices generated, IRP-registered and paired with a valid e-way bill, then pushed back to AVC - fully GST-compliant.

Appointments & ASN

Appointments fetched from AVC and shared with your 3PL, with carton-level ASN tracked end to end.

GRN reconciliation

PO ↔ ASN ↔ invoice ↔ GRN matched the moment goods are received, surfacing every short-receipt instantly.

Chargeback & shortage recovery

Every deduction validated against shipment and contract data, with evidence compiled and disputes filed inside Amazon's window.
