Version control for FMCG forecasting means every forecast carries a number, an owner, a timestamp and a status, so nobody has to ask which spreadsheet is current. A snapshot freezes the forecast at a set moment, a promotion step moves it from draft to approved, and an audit trail records every change and who made it. Spreadsheets handle this poorly: studies of company spreadsheets have found error rates from 24 percent to over 85 percent, with version control and validation often neglected. Demand and supply teams can see a governed forecast history built from their own files in a short session.
Retire "Forecast_Final_v7_REAL" and Know Which Number Is Approved
iFactory AI, an on-premise industrial AI platform, keeps each forecast as a numbered, approved and traceable version linked to the daily replan.
What Is Version Control for Demand Forecasts?
It is a set of rules that keeps one approved forecast, preserves every earlier one and records who changed what. The numbers below show why spreadsheets struggle with it.
What Is a Forecast Snapshot and When Should You Take One?
A snapshot is a copy of the forecast taken at a set time, so you can look back at what the forecast was and when it changed (StockIQ). Teams can ask for a snapshot cadence template to adapt.
| Snapshot | Trigger | Why Keep It |
|---|---|---|
| Daily replan | Each automatic forecast run | Shows how the plan moved day to day |
| Weekly review | Planner review meeting | Records what the team saw and decided |
| Consensus lock | Sales, supply and finance sign-off | The number the plant builds against |
| Month-end S&OP | S&OP meeting close | Baseline for accuracy and bias review |
| Post-promotion | Promotion window ends | Compares uplift planned against uplift achieved |

Which States Should a Forecast Move Through?
A forecast should only move forward through named states, and only a named role can move it.
Who Can Promote a Forecast to Approved?
Promotion approval separates people who edit from people who sign. Teams can review a promotion approval matrix with iFactory AI's team.
| Role | Edit Draft | Approve | Freeze | View History |
|---|---|---|---|---|
| Demand planner | Yes | No | No | Yes |
| Sales and marketing | Comment only | No | No | Yes |
| Supply planner | No | No | No | Yes |
| S&OP lead | No | Yes | Yes | Yes |
| Finance | No | Yes, for budget view | No | Yes |
What Belongs in the Audit Trail?
Version every forecast and keep the model's original number beside any human override, along with the inputs behind each projection (Outreach). Eight fields cover most audits.
How Do You Compare Two Versions Quickly?
A version comparison should show what moved and why, by driver. The bars show an illustrative change between version 11 and version 12.
How Do Snapshots Help You Measure Forecast Error?
Error is only meaningful at a stated lead time. Comparing actual sales with the snapshot taken one, four and twelve weeks earlier shows how far ahead the forecast can be trusted. Planners can walk through a lag accuracy view built from their own history.
| Snapshot Lag | Compared With | What It Tells You |
|---|---|---|
| 1 week before | Actual sales | Whether the near-term plan is dependable for production |
| 4 weeks before | Actual sales | Whether materials and packaging can be committed |
| 12 weeks before | Actual sales | Whether capacity and listing decisions were sound |
Which Version Mistakes Cause the Most Rework?
How Does a Daily Replan Work Beside a Frozen Forecast?
A frozen forecast protects the plan inside the planning window, while a daily replan keeps adjusting the outlook beyond it. Both can run without confusing each other when each is versioned.
Where Does iFactory AI Fit in Forecast Version Control?
iFactory, an on-premise AI platform for manufacturing, ties forecasts to the daily replan so every plant plan can name the version it came from.
Numbered Versions
Each forecast run is saved as a version with a clear status.
Approval Steps
Only named roles can promote a version to approved.
Override Records
Model numbers and manual changes are stored side by side.
Plan Traceability
Daily replans show which approved version they used.
Expert Review: Judging a Forecast Version Process
Frequently Asked Questions
Why is Excel a poor tool for forecast version control?
Excel has no native version control, so two people can overwrite each other and a stale file can circulate for weeks. Studies of company spreadsheets report error rates from 24 to over 85 percent (SOA, 2013). See a governed version flow on your own data.
How often should we snapshot an FMCG forecast?
Snapshot at every daily replan, at each weekly review, at consensus lock and at month-end S&OP, and keep them long enough to measure error. A snapshot is a copy taken at a set time (StockIQ). Plan your cadence with our team.
Who should approve the forecast?
Usually the S&OP lead approves and freezes, with finance signing the budget view, while planners edit drafts and cannot approve their own. This separation prevents silent changes. Ask support for an approval matrix to adapt.
What should an audit trail record for a forecast override?
Record the model's original number, the override value, who changed it, when, why and the inputs used (Outreach). That lets you measure whether overrides add value. See an override record in a short demo.
Does iFactory AI replace our S&OP process?
No. Your meetings and sign-offs stay. iFactory AI stores the versions, approvals and overrides, and links each daily replan to the approved forecast. Walk through the flow with our team.
