CSA Models for Small Farms

What is a CSA in simple terms?

In a CSA, members pay the farm in advance, or in installments, for a share of the harvest during a season. The farm gets early money for seed, supplies and labor, and members get regular products and a direct link to the farm. The details vary widely from farm to farm.

The idea involves shared risk. In a poor season, shares may be smaller, and in a good season, larger. How much risk you ask members to share is something to decide, and to explain clearly.

Think about the pickup system, since it shapes your labor and your members' experience. On-farm pickup is simple but may be far for members. Drop sites at a market or business save members time but need partners, coolers and clear rules. Home delivery adds cost and time.

What is the traditional share model?

In the traditional model, members pay a set amount before the season for a weekly or biweekly box of whatever is ready. Pickup happens at the farm or at a set location. It offers early cash and a predictable plan, but members must accept what is in the box, and the farm must produce a steady supply.

This model suits farms with a variety of crops and a staggered planting plan. It asks more of members, who need to like variety and be willing to cook with what they receive.

Consider how payment works. Some farms take one payment, some offer installments and some accept payment through programs for food assistance. Ask your state department of agriculture and your extension office what programs exist locally and what paperwork they require.

What other models can I use?

Some farms offer a credit or market-style model, where members prepay and choose items from a table or an online list, drawing down a balance. Others offer half shares, work shares where members trade labor for part of the cost, or add-on shares such as eggs, flowers or meat.

Some CSAs partner with other farms to provide a wider mix. Each model changes how you plan, pack and communicate, and rules on selling products from other farms may apply. Ask your state department of agriculture.

Look at how other CSAs in your area run, and see what they charge, what they offer and where they pick up. You do not need to copy them, but knowing the local market shows where you can fill a gap rather than compete head to head.

• Traditional prepaid box
• Credit or choice-based model
• Half shares and work shares
• Add-on shares from your farm or partner farms

How do I choose a model for my farm?

Think about your crops, labor, space and customers. A farm with limited variety may prefer a credit model that lets members pick what they want. A farm with strong variety and a loyal community may prefer the traditional model. A farm with little time for packing may prefer a choose-at-pickup system.

Ask potential members what they want. Surveys at markets or among friends will show what price range, pickup times and flexibility people prefer. Compare their answers with what you can reliably supply.

How do I decide on pricing and share size?

Start with cost of production and your planned yield. Divide the total cost, including labor and delivery, by the number of members and weeks. Compare the result with what similar CSAs and local stores charge. Do not guess at pickups or yields; use your records.

Plan for a smaller number of members at first. It is easier to grow a waiting list than to fill shares you cannot supply.

What rules and risks apply?

Rules on licensing, food safety, labeling, delivery and sales tax vary by state and locality, and some apply to CSA sales. Ask your state department of agriculture, local health department and a tax preparer what applies to you. Ask your insurance agent about coverage for pickup sites and deliveries.

Write a clear member agreement that explains what members are buying, what happens in a poor season, missed pickups, refunds and communication. Ask an attorney to review it, since this article is not legal advice.

How do I start small?

Begin with a handful of members, such as friends and neighbors, for a short season. Treat it as a pilot, and learn what works. Keep notes on what you packed, how long it took and what members said.

After the season, review costs, hours and feedback, then decide whether to grow, change the model or return to other markets.
