Seasonal Business Finance — How to Manage Cash When Revenue Comes Once a Year

Revenue Comes Once. Costs Come Every Month.

For seasonal businesses — agriculture, holiday retail, ski resorts, construction — the financial management problem is fundamentally different from businesses with smooth revenue curves. Costs are continuous: wages, rent, insurance, debt service, seed stock, inputs. Revenue is episodic: it comes in a 6-8 week harvest window, or Q4, or summer season. The months between revenue events are a cash management exercise that determines whether the business survives to the next season.

An agricultural seed company we worked with had this problem in acute form. Revenue was concentrated in the planting season — March through May. The rest of the year, the business was spending to prepare: seed development, inventory buildup, grower relationships, working capital for the growing season. By April, the company's cash position was at its lowest point of the year, just as it needed maximum operational capacity.

Biological Asset Valuation: The Complexity Under the Surface

Agricultural businesses have a finance complexity that doesn't exist in most other sectors: biological assets. Seed stock in development, growing crops, and livestock are assets that change in value as they develop — not because market prices change, but because biological progress occurs. Accounting for these assets requires valuation at fair value less costs to sell (under IAS 41), and tracking the value change as income or expense in each period.

Most small and mid-size agricultural businesses don't do this properly. They value biological assets at cost of production, which understates asset values at late stages of development and creates lumpiness in reported income (all the gain appears at harvest). Getting the biological asset valuation right matters for lenders — agricultural credit facilities are often sized based on asset values, and an undervalued growing crop means an undersized credit facility precisely when cash is tightest.

In the seed company engagement, proper biological asset valuation increased the reported asset base at the April trough point — historically the company's weakest balance sheet moment — by approximately 23%. This directly supported the credit facility negotiation, expanding available working capital at the season's low point from a position of inadequate to adequate.

The 12-Month Cash Map

The tool that changed financial management for this business was a 12-month rolling cash map — week by week for the next 8 weeks, month by month for the remainder. The map showed: cash from prior season receivables collecting, cash for current season input purchases going out, credit facility draw and repayment schedule, and the projected cash position against the minimum operating buffer.

With this map, the company could plan credit facility drawdowns 6-8 weeks in advance — not when cash hit zero, but when the model showed the gap approaching. It could time supplier payments to smooth the pre-season cash dip. It could identify the two or three weeks each year where the combination of input purchasing and delayed collection created a genuine liquidity risk — and prepare for them rather than discover them.
