Setting Up Forecast Guidelines
Quick Answer: Forecast guidelines are business rules you share with Mo to apply bulk adjustments across your catalog. Define rules for seasonality, regional demand, growth rates, and SKU-level behavior, then let Mo process them across hundreds or thousands of products at once.
What Are Forecast Guidelines?
Forecast guidelines are structured business rules that tell Mo how to adjust your directional forecast based on your knowledge of the business. Instead of editing SKUs one by one, you describe patterns and rules that Mo applies across your entire catalog.
Guidelines typically cover:
Seasonality — How demand shifts throughout the year for different product categories
Regional weightings — How demand varies across sales channels or geographies
Growth assumptions — Expected growth or decline rates by category or product line
SKU-level logic — Specific rules for individual products or product groups
Forecast Guidelines Template
Use the template below to document your guidelines before sharing them with Mo. Fill in the rows that apply to your business, delete the example rows, then upload the completed file via the paperclip icon in the Mo chat and ask Mo to update your forecast based on the guidelines.
How to use this template with Mo:
Copy the table into a spreadsheet or text file and fill in your rules
Save the file (CSV, Excel, or plain text all work)
Open Mo in your Moselle chat
Click the paperclip (📎) icon to attach the file
Send a message like: "Please update my forecast based on these guidelines"
Tips: Fill in as many or as few rows as you need. Delete any example rows before uploading. The more specific you are with percentages, dates, and product names, the more precisely Mo can apply each rule.
HOW TO USE
Fill in each row that applies to your business. Delete example rows. Add as many rows as needed. Once complete, share this file with Mo in your Moselle chat and ask Mo to re-apply your forecast based on these guidelines.

Prerequisites
Before setting up forecast guidelines, make sure you have:
Building Your Seasonality Rules
Seasonality is often the most impactful set of guidelines you can provide. These rules tell Mo how demand for different product categories fluctuates throughout the year.
How to Define Seasonality Rules
Identify Your Seasonal Categories
Group your products by how seasonality affects them:
Highly seasonal — Products with dramatic demand swings (e.g., swimwear, holiday gifts, outdoor equipment)
Moderately seasonal — Products with noticeable but less extreme shifts (e.g., fitness apparel, skincare)
Non-seasonal — Products with steady demand year-round (e.g., everyday basics, consumables)
Don't over-categorize. Start with 3–5 seasonal groupings. You can always add granularity later.
Quantify the Seasonal Impact
For each seasonal category, estimate the demand change by month or quarter:
Example seasonality rules:
"Outdoor furniture: +50% April through September, -30% November through February"
"Holiday gift sets: +200% in November, +300% in December, return to baseline in January"
"Everyday basics: flat year-round, no seasonal adjustment"
"Fitness equipment: +40% January through March, -10% June through August"
Share with Mo
Open the Mo chat and provide your seasonality rules. Be specific about which categories are affected and the magnitude of the adjustment.
Example prompt: "Apply these seasonality rules to my 2026 forecast:
Outdoor furniture increases 50% from April through September and decreases 30% from November through February
Holiday gift sets increase 200% in November and 300% in December
Everyday basics remain flat with no seasonal adjustment
Fitness equipment increases 40% January through March"
Defining Regional and Channel Weightings
If you sell across multiple channels or regions, demand patterns may vary significantly. Channel weightings help Mo distribute your forecast appropriately.
When to Use Channel Weightings
You sell through both wholesale and direct-to-consumer with different demand curves
Certain marketplaces (Amazon, Shopify) show different seasonality than your own website
Geographic regions have distinct demand patterns
How to Set Up Channel Weightings
Describe the relative demand differences across your channels:
Example guidelines:
"Amazon typically represents 60% of our total demand, Shopify 25%, and wholesale 15%"
"Wholesale orders are concentrated in Q1 and Q3 for pre-season buys"
"Our Amazon channel has a stronger BFCM spike—2.5x vs. 1.5x on Shopify"
"International channels lag domestic trends by approximately 4–6 weeks"
You don't need exact percentages. Directional guidance like "Amazon is our largest channel and spikes harder during promotions" gives Mo enough context to apply meaningful adjustments.
Setting Growth Assumptions
Growth assumptions tell Mo how you expect demand to evolve beyond what historical patterns suggest.
Types of Growth Assumptions
Category growth
Expected growth rate for an entire product category
"Our protein bar category is growing 25% year-over-year"
Channel growth
Expected growth for a specific sales channel
"Amazon sales growing 30% YoY after our advertising push"
Decline rates
Expected decrease for products being phased out
"Legacy packaging SKUs declining 15% monthly"
Flat assumptions
Categories expected to maintain current levels
"Core basics should remain flat, no growth expected"
How to Apply Growth Assumptions
Define Your Assumptions
Create growth rules based on your business strategy and recent performance:
Example prompt: "Apply these growth assumptions:
Protein bars: grow 25% YoY across all channels
Premium supplements: grow 15% YoY
Legacy packaging SKUs: decline 15% per month until discontinued
Core basics: flat, no growth adjustment"
Creating SKU-Level Logic
Some products need rules that don't fit neatly into category-level guidelines. SKU-level logic lets you define behavior for specific items or small groups.
Common SKU-Level Rules
New product launches:
"New protein bar (SKU-2468) launches March 15 — ramp to full velocity over 8 weeks using our chocolate bar launch as a comparable"
Promotional items:
"SKU-1357 is our BFCM hero product — 3x normal demand in November, with a 2-week tail into December"
Discontinuation:
"SKU-9876 is being phased out — reduce forecast by 20% per month starting April, zero by August"
Constrained supply:
"SKU-5555 is supply-limited to 500 units per month until our new supplier comes online in Q3"
Bundled products:
"When we run the holiday bundle, the individual SKUs in the bundle should decrease by the percentage of sales expected from the bundle"
Keep SKU-level rules for items that genuinely need individual attention. If a rule applies to an entire category, define it as a category-level guideline instead.
Organizing Your Guidelines Document
As your guidelines grow, it helps to organize them in a structured way. Consider this format when sharing with Mo:
Category Rules:
List broad rules that apply to product groups
Channel/Regional Rules:
List rules specific to sales channels or geographies
Growth Assumptions:
List forward-looking growth or decline rates
SKU-Specific Rules:
List rules for individual products that need unique treatment
Promotional Calendar:
List upcoming promotions with expected demand impact and timing
Save your guidelines document externally so you can reuse and refine it each planning cycle. Over time, your guidelines become a valuable playbook for demand planning.
Recommended Workflow
Frequently Asked Questions
How many guidelines should I start with?
Start with 5–10 rules covering your most impactful categories and seasonal patterns. You can always add more granularity in subsequent cycles.
Can I update guidelines after applying them?
Yes. You can share updated guidelines with Mo at any time. Mo will adjust the forecast based on your latest rules, preserving any surgical edits you've already made unless the guideline directly conflicts.
Do guidelines carry over between forecast cycles?
Guidelines are applied per conversation with Mo. Save your guidelines externally so you can reuse and refine them each planning cycle.
What if my guidelines conflict with each other?
If Mo detects conflicting rules (e.g., a category growth rule and a SKU decline rule for the same product), it will ask for clarification. Be as specific as possible to avoid ambiguity.
How do I know if my guidelines improved the forecast?
Track your MAPE scores in the Forecast Performance Report before and after applying guidelines. Over multiple cycles, you should see accuracy improve as your guidelines capture business dynamics the model alone cannot detect.
