Guide To Sales And Operations Planning For Manufacturers

Sales and Operations Planning, or S&OP, is the process of aligning demand, supply, inventory, capacity, and business priorities.

In plain language, it is the meeting where sales promises, production reality, purchase constraints, stock position, and financial priorities are forced to sit at the same table.

Without S&OP, companies run in fragments. Sales pushes urgent orders. Production complains about material. Purchase says vendors are delayed. Stores says stock is blocked. Finance worries about cash. Management hears all of this separately and makes decisions late.

A good S&OP process does not remove uncertainty, but it makes the uncertainty visible early.

AICAN Optiwise helps manufacturers connect the data behind S&OP: sales orders, inventory, purchase, production, dispatch, and reports.

What Is S&OP?

S&OP is a regular planning process that balances what the market wants with what the business can realistically supply.

It usually includes:

• Demand review
• Supply review
• Inventory review
• Production capacity review
• Purchase and vendor review
• Financial impact review
• Decision meeting
• Execution follow-up

The goal is not a perfect forecast. The goal is coordinated decisions.

Why Manufacturers Need S&OP

Manufacturers live with constraints. Material may not arrive on time. Machines may have limited capacity. Labour may be unavailable. Customer priorities may change. Cash may limit buying. Vendors may extend lead times.

S&OP helps teams make trade-offs before the factory is already in crisis.

It answers questions like:

• Which orders are truly committed?
• Which products need priority?
• Which material shortages can stop production?
• Which inventory is too high?
• Which capacity bottlenecks are coming?
• Which customers need delivery commitment review?
• Which purchase decisions affect cash flow?

Demand Review

The demand review looks at what customers may need.

Inputs include:

• Confirmed sales orders
• Forecasts
• Repeat customer patterns
• Open enquiries
• Lost orders
• Seasonal trends
• Market signals
• Customer priority changes

Sales should not simply submit an optimistic number. The demand plan should separate confirmed demand, likely demand, and speculative demand.

Supply Review

The supply review checks whether the business can fulfil demand.

It includes:

• Available stock
• Work-in-progress
• Production capacity
• Machine constraints
• Labour availability
• Vendor lead times
• Purchase order status
• Quality issues
• Subcontracting capacity

This is where production and purchase reality must challenge the demand plan constructively.

Inventory Review

Inventory is the buffer between demand and supply, but it is also cash.

S&OP should review:

• Raw material stock
• Finished goods stock
• Slow-moving inventory
• Critical shortages
• Overstocked items
• Safety stock levels
• Inventory ageing
• Stock value

Good S&OP reduces both stock-outs and unnecessary stock buildup.

Decision Meeting

The decision meeting should not be a long status update. It should make decisions.

Typical decisions include:

• Which orders get priority
• Which material to buy now
• Which production plan to freeze
• Which delivery promises need revision
• Which inventory to liquidate
• Which capacity constraint needs action
• Which customer or vendor escalation is needed

Without decisions, S&OP becomes a reporting ritual.

How ERP Supports S&OP

S&OP depends on reliable data. ERP helps by bringing operational information into one system.

A connected ERP can show:

• Confirmed sales orders
• Pending dispatches
• Inventory availability
• Purchase order status
• Production plan and progress
• Capacity signals
• Vendor delays
• Customer outstanding
• Stock ageing
• Forecast versus actual movement

Optiwise by AICAN helps manufacturers run planning from live operational data rather than separate department spreadsheets.

Practical S&OP Rhythm

A simple monthly rhythm can work:

1. Week 1: Update demand and order data.
2. Week 2: Review supply, inventory, and capacity.
3. Week 3: Identify gaps and scenarios.
4. Week 4: Leadership decision meeting and execution plan.

Fast-moving businesses may need weekly mini-S&OP reviews.

Where AICAN Optiwise Fits

AICAN helps manufacturing businesses move from reactive follow-up to structured planning. AICAN Optiwise connects sales, inventory, purchase, production, and reporting so S&OP decisions are based on current data.

Founder’s Note

S&OP works when teams stop defending their own data and start solving the company’s constraints together.

At AICAN, we believe planning should feel practical, not corporate. The right ERP gives teams a shared operating picture so decisions are faster and less emotional.
