Seasonal Forecasting and Peak Planning

Every business has a seasonality profile — the pattern of high and low demand across the year. Some are obvious (Christmas gifts, summer holidays) and others are subtle (B2B businesses often slow in August when clients are on holiday; accountancy software spikes at tax return deadlines).

AskBiz calculates your seasonality profile by comparing each month's revenue to the annual average across 2+ years of data. The result is a seasonality index for each month — a number above 1.0 indicates a peak month; below 1.0 indicates a trough.

To view your profile: Finance → Forecasting → Seasonality Profile.

Once your seasonality profile is established, AskBiz projects the expected revenue for your next peak period based on:

• Your current annualised revenue run rate
• Your historical seasonality index for the peak period
• Any trend (growth or decline) applied to the seasonality baseline

Example: if your average monthly revenue is £80,000 and your December seasonality index is 2.1, your December forecast baseline is £80,000 × 2.1 = £168,000.

Go to Finance → Forecasting → Peak Planner to see your next peak forecast and the planning checklist AskBiz generates from it.

Your peak revenue forecast drives your inventory planning. AskBiz calculates the implied unit volume for each SKU at peak, based on:

• Current selling price and average order value
• Historical product mix during the equivalent peak period
• Your lead time for each product category

The Peak Planner generates a recommended pre-peak stock order — the quantity to order, and the date by which the order must be placed to arrive before peak demand starts.

Access via Inventory → Peak Planning → Order Recommendations. Export as a purchase order template to share with your suppliers.

Peak periods require higher marketing investment to capture demand — but the ROI of that spend varies significantly by channel and by how early you start.

AskBiz shows your Revenue per £ of Marketing Spend by channel during prior peak periods. Use this to allocate your peak marketing budget to the highest-returning channels first.

Key planning dates to set in AskBiz:

• Start of peak marketing campaign (when to increase ad spend)
• Peak revenue window (Black Friday, Christmas week, etc.)
• Stock arrival date (must precede peak marketing launch)
• Post-peak clearance campaign (if applicable)

Add these as events in Finance → Calendar → Add Event so they appear on your planning timeline.

Revenue peaks create operational peaks: more orders to pick, pack, and ship; more customer service enquiries; more returns to process after the peak.

AskBiz estimates your peak order volume based on your revenue forecast and average order value. Use this to calculate:

• Additional temporary staff needed (peak orders ÷ orders processed per person per day)
• Packaging and postage costs (at your per-order rate)
• Expected return volume (at your historical return rate)

If you use a 3PL for fulfilment, share your AskBiz peak forecast with them at least 8 weeks before peak so they can reserve capacity. Many 3PLs charge premium rates for space reserved less than 4 weeks before a peak period.
