← Back to glossary Category: Operațional Available-to-Promise flow Quick answer: The flow that computes in real time what quantity can be promised to a customer and when, based on real stock and already-allocated orders. Key takeawaysPhysical stock available per locationQuantities already allocated/reservedConfirmed inbound (supplier orders, production)Allocation and prioritization rules What Available-to-Promise flow is Available-to-Promise (ATP) flow is the mechanism that answers live: 'can I promise this quantity, on this date?'. It takes physical stock, minus what's already allocated to other orders, plus confirmed replenishment inbound, and computes the real promise. Why it matters to the board Promises based on inaccurate stock lead either to overselling (accepted orders that can't ship → backorder, cancellations) or underselling (refusing orders for goods that actually exist). Correct ATP protects both sales and trust. What it accounts for Physical stock available per location Quantities already allocated/reserved Confirmed inbound (supplier orders, production) Allocation and prioritization rules How Azuvio helps Azuvio surfaces live availability (ATP) in the B2B portal and the order flow, so every delivery promise is realistic first time — including across stock distributed over multiple locations. Frequently askedIs ATP the same as available stock?Not quite. Available stock is what you physically have; ATP is what you can realistically promise, after subtracting existing allocations and adding confirmed inbound.Why is ATP a flow, not just a number?Because it recalculates continuously as orders, allocations and replenishments arrive — it must be orchestrated live, not computed once a day.
