Why manufacturers still use Excel for this
Monthly planning is the horizon where S&OP (Sales and Operations Planning) discipline lives. Daily and weekly schedules execute; monthly plans decide. How much capacity to commit to which product family. Whether to hire, run overtime, or carry inventory. Which customer orders to accept for the period ahead.
Most small manufacturers do monthly planning informally — sales has a number, operations has a capacity, the gap gets debated and resolved without explicit data. This template makes the data explicit: forecast demand by family, available capacity by work center, beginning and ending inventory targets, identified capacity gaps.
Done well, monthly planning surfaces decisions 30–60 days before they become emergencies. The capacity gap at the press 6 weeks from now becomes hire-a-second-operator now, not pay-double-overtime then. Most shops adopt this discipline once and never go back.
What's inside the template
Product family forecast
Per family, forecast quantity for the month. Combined sales-pipeline + historical run rate + customer commitments.
Capacity required per family
Forecast quantity × hours per unit = required hours by work center per family.
Capacity available
Per work center, available hours per month (shift hours × days × number of machines minus planned downtime).
Capacity gap report
Required vs available, per work center, per family. Negative = shortfall (overtime, expedite, push date, hire); positive = surplus (sales push or maintenance window).
Beginning + ending inventory
For each family, beginning inventory + production - shipments = ending inventory. Inventory target by family informs production volume.
Aggregate plan output
Final monthly production target per family, reconciled with capacity and inventory targets. This is the input to the weekly plan.
How to use this template
A practical walkthrough, from the sample data to a plan built on your own numbers.
- 1
Plan one month ahead with 60-day visibility
Monthly plan covers next month's production. Forecast extends 60 days so the plan-after-next is visible too. Six weeks of forward visibility is the sweet spot for actionable planning.
- 2
Reconcile sales forecast with production capacity
Sales forecast that exceeds capacity is not a plan — it is a wish. The reconciliation conversation (S&OP) decides what gets cut, added, or pushed. Without explicit reconciliation, the forecast lies.
- 3
Use product families, not individual SKUs
Monthly planning at the SKU level is too granular and unstable. Product families (similar process, similar capacity profile) make the planning robust. Disaggregate to SKU at the weekly level.
- 4
Hold monthly S&OP meeting
The output of this template is the input to the monthly S&OP meeting (sales, operations, planning, sometimes finance). The decisions made there set the direction for the next 30–60 days.
When you outgrow this template
Excel is the right answer for early-stage planning, until it isn't. These are the warning signs that you need a real production scheduling tool.
If three or more of these apply, you have outgrown spreadsheet planning. EDGEBIC, the current generation of RMDB, is User Solutions' finite capacity scheduling and production planning software. It imports the same orders, routings, work centers and stock from Excel, CSV or your ERP, schedules them against real machine, labor and material limits, and shows the result on a drag-and-drop Gantt chart. It is a one-time license: EDGEBIC APS is $25,000, and EDGEBIC Complete, which adds MRP, inventory and purchasing, is $35,000.

Frequently asked questions
What is a "product family" for planning purposes?+
A group of SKUs that share process route and similar capacity requirements. For a machine shop, this might be "small precision parts" vs "large structural parts." For food manufacturing, "frozen products" vs "shelf-stable." Family granularity is shop-specific — typically 5–20 families covers most operations.
How does monthly planning relate to S&OP?+
S&OP is the process of reconciling demand (sales forecast) with supply (production capacity) at a monthly horizon. The monthly production plan template is the substrate of S&OP — the data the cross-functional team reviews to make decisions about capacity, inventory, and customer commitments.
How accurate does the monthly forecast need to be?+
Accuracy improves over the planning horizon: 30 days out should be within 10–15% at the family level; 60 days out within 20–25%. Demand at the SKU level is always less accurate than at the family level. Plan capacity at the family level; resolve SKU detail at the weekly level.
What if sales forecast and production capacity do not match?+
That is the point of the planning meeting. Options: increase capacity (overtime, hire, second shift, outsource), reduce demand (push customer dates, deprioritize speculative orders), or change inventory position (build ahead to use future capacity). The template makes the gap visible; the meeting makes the call.
Start with the spreadsheet. Move to EDGEBIC when it breaks.
The template handles the math for a small plan. EDGEBIC is what manufacturers move to when orders, routings and capacity change faster than a spreadsheet can follow: published one-time pricing, and implementation measured in days.
