What is S&OP (Sales and Operations Planning)?
S&OP is a recurring cross-functional process that aligns demand, supply, and financial plans into a single agreed operating plan.
Definition
Sales and Operations Planning (S&OP) is a structured monthly process that brings sales, marketing, operations, supply chain, and finance together to balance demand and supply over a medium-term horizon. It reconciles the demand plan with production capacity, inventory targets, and financial goals so the organization operates from one consensus plan. The output guides decisions on capacity, inventory builds, sourcing, and budgets. Mature programs extend this into integrated business planning (IBP), tying operational plans more tightly to financial outcomes.
How S&OP Works in ERP
ERP and supply-chain planning modules aggregate demand forecasts, sales data, inventory positions, and capacity into product-family views that support the S&OP review cycle. Planners run scenarios to test demand changes or capacity constraints, and the agreed plan feeds master scheduling, MRP, and budgeting. Some vendors provide dedicated S&OP or IBP applications layered on top of the transactional ERP for collaboration and what-if analysis.

Frequently Asked Questions
How is S&OP different from master scheduling?
S&OP operates at an aggregate, product-family level over a medium-term horizon and is a cross-functional consensus process. Master scheduling is the more detailed, shorter-term plan at the individual product level that drives MRP. S&OP sets the strategic envelope within which master scheduling and detailed planning then execute.
What is the relationship between S&OP and IBP?
Integrated Business Planning (IBP) is generally considered an evolution of S&OP that extends the process to incorporate financial planning, scenario modeling, and a longer horizon. Where classic S&OP focuses on balancing demand and supply, IBP explicitly ties those plans to revenue and profit targets. Many ERP and planning vendors now market IBP-branded modules.
