    Quick commerce reconciliation, defined.

    The vocabulary of order-to-cash — from the purchase order a platform raises to the payment advice that finally settles it. Plain definitions, and why each one decides whether you get paid.

    Purchase Order(PO)
    The order a retailer or platform raises on a brand, specifying SKUs, quantities and delivery terms. Every rupee you eventually collect traces back to a PO, so the PO is the anchor record for the whole order-to-cash cycle. When POs arrive scattered across email and platform portals, teams lose the one reference they need to prove what was actually asked for.
    Sales Order(SO)
    The brand's internal order created from a PO, used to allocate inventory and trigger fulfilment. The PO to SO conversion is where an external commitment becomes an internal one, and where quantity decisions get made. If the SO quietly differs from the PO, the gap surfaces much later as a short supply or an invoice mismatch.
    Goods Receipt Note(GRN)
    The document a buyer issues on receiving goods, recording the quantity actually accepted. It is the reference point for detecting short supply. Because payment is settled against accepted quantity rather than dispatched quantity, a GRN that arrives late, or never arrives at all, directly holds up cash.How GRN reconciliation works
    Proof of Delivery(POD)
    Confirmation that a shipment was delivered, used as evidence in claims and recovery. Without a POD, a disputed delivery is your word against the platform's. With one, a claim becomes an evidence-backed recovery action rather than a negotiation.
    Order-to-cash(O2C)
    The full cycle from receiving a purchase order to collecting the payment for it, including invoicing, delivery, reconciliation and collections. Most teams have good visibility over the first half and very little over the second. The leakage lives in the second half, after dispatch.The full order-to-cash sequence
    Fill rate
    The share of ordered quantity that was actually supplied and accepted, expressed as a percentage. It is the cleanest single measure of how reliably you serve a channel, and platforms watch it closely. A falling fill rate usually shows up in revenue before anyone reads it as an operational signal.
    Short supply
    The gap when the quantity accepted on the GRN is lower than the quantity ordered or dispatched. Short supply is quietly expensive because the invoice may still say one number while the payment reflects another. Catching it at GRN stage is the difference between a correction and a write-off.How short supply is detected
    Deduction note
    A document from the buyer reducing the payable amount against an invoice, for reasons such as shortages, damages, or claims. Deductions are legitimate often enough that teams stop challenging them, which is exactly how unexplained ones slip through. Mapping every deduction back to its underlying reason is what makes the invalid ones visible.How deductions are traced back
    Payment advice
    The remittance statement a buyer sends explaining which invoices a payment covers and what has been deducted. Matching payment advices back to invoices is how you find out whether you were paid in full, in part, or for something else entirely. Until that reconciliation happens, a bank credit is not the same as a settled invoice.
    Revenue leakage
    Money a brand has earned but never collects — lost to short supplies, missing GRNs, invoice mismatches, unexplained deductions and unpaid or delayed invoices. None of these are dramatic on their own, which is why they accumulate unnoticed. Leakage is the sum of every small gap nobody owned.
