What is 'Available To Promise' ATP?

Available To Promise (ATP) is an inventory management approach used to ensure that customer expectation and satisfaction is managed by correctly identifying and managing inventory on hand and in supply to meet the market demand and supply chain throughput.

Why use 'Available To Promise' ATP?

When calculated and managed correctly, Available To Promise (ATP) allows businesses to sustain the minimum levels of stock within inventory to:

  • Reduce warehousing costs.
  • Reduce dwell time (inventory remaining on racking / shelves for extended periods).
  • Avoid / reduce back orders (which in turn reduces customer confidence and typically adds supply chain costs for expedited delivery).
  • Meet customer expectations via Push/Pull based planning.

Most established companies leverage a combination of Push and Pull Available To Promise strategies to manage specific stock/product lines across specific markets/target demographics.

What is Push Based 'Available To Promise' ATP?

Push Based Available To Promise (PBATP) leverages demand forecast based on historic sales / new sales / growth market models to allow sufficient uplift of stock / increase in supply chain throughput to meet the needs identified above.

What is Pull Based 'Available To Promise' ATP?

Pull Based Available To Promise (PBATP) focuses on the business 'here and now' whereby warehousing and supply chains are fixed / limited and/or demand is unknown (no forecast material or market trend) or unpredictable (subject to unknown quantities such as machinery failure, environmental issues etc.).
