How to Plan for Seasonality

1. Build Cash Reserves in Peak Months

Save 30-40% of profits from Nov-Dec to cover Jan-Feb slow period. Aim for 3 months operating expenses in reserve.

2. Adjust Marketing Spend

Increase marketing 2 months before peak seasons. Reduce spend during slow months or focus on long-term brand building.

3. Flexible Staffing

Hire temporary staff for peak months (Nov-Dec). Use freelancers during slow periods instead of full-time hires.

4. Negotiate Payment Terms

Request shorter payment terms (Net 14) during slow months. Offer early payment discounts in Jan-Feb to improve cash flow.

5. Plan Major Expenses

Schedule equipment purchases, office moves, or major investments for peak revenue months (May-June, Nov-Dec).

6. Diversify Revenue Streams

Add counter-seasonal products/services. If retail peaks in Dec, add B2B services that peak in March/June.
