A herd share is the most legally careful recurring subscription a small farm will ever run. You are not selling milk. Your members own a share of the herd, and the money they send every month is a boarding fee — the cost of you feeding, milking, and caring for an animal that is partly theirs. The milk is theirs already, because the cow is theirs already. That one distinction is why the whole thing exists, and it's why you can't just ring up a gallon.
Search "herd share" and you'll drown in the same three results: a Wikipedia entry, a stack of contract templates, and legal explainers arguing about which states allow it. All useful, up to a point. None of them tell you the thing that actually eats your time: how to run the share after the paperwork is signed. Who's paid this month. Who's two months behind. Who's away for a week. What happens to everyone's share when your best cow dries off before she calves.
That's the operations gap, and it's where a herd share quietly turns into a spreadsheet, a text-message collection service, and a clipboard at the barn door. This guide is about closing that gap.
What a herd share actually is (and why it's billed the way it is)
The structure is deliberate. A member signs a bill of sale or membership agreement and buys a fractional interest in the herd — a 1/25 share, a 1/50 share, whatever your milk output divides into cleanly. From then on they pay a recurring boarding fee (some agreements call it an agistment fee) that covers your real costs: feed, labor, vet care, overhead. In return they collect their portion of the milk on a set schedule.
Because it is ownership plus a care fee — not a sale — the money is flat and recurring, not per-gallon. You bill the fee whether the milk was heavy or light that week, the same way a boarding stable charges to keep a horse regardless of how often you ride. Get that framing right and the billing model falls out of it naturally: a subscription, not a checkout.
One honest caveat before anything else. Whether a herd share is legal, and on what terms, varies enormously from state to state — and the public "laws by state" lists openly contradict each other. Some states recognize herd shares explicitly, some tolerate them with no statute either way, and a handful prohibit them outright. Transporting raw milk across state lines for human consumption is a separate federal matter. This is an operations guide, not legal advice. Confirm your own state's rules with your state department of agriculture, and have an attorney review your agreement, before you run a single share.
The rhythm you're actually managing
Strip away the legal language and a herd share runs on a predictable loop. This is the shape of the thing — and the part spreadsheets lose track of is the fourth step, not the first.
Run it like a CSA, because the mechanics are identical
Here's the insight that saves you from building anything custom: a herd share is operationally a CSA with one product. A season you sell up front, money collected against a promise, and a fixed pickup schedule. TallyTill's CSA and share-plan tools were built for exactly that pattern, so you don't need a herd-share "mode" — you set a herd share up the same way you'd set up a vegetable CSA or a whole-animal meat share. Here's how each piece of a herd share maps:
| What a herd share needs | How you run it |
|---|---|
| The recurring boarding fee | A share plan with a set cadence — weekly, monthly, or prepaid by the quarter or season. The plan tracks what each member owes and when, so collection isn't a monthly round of reminders. |
| Knowing who's paid and who's behind | Each member has an account with a running balance. The overdue list is one screen, not a number you carry in your head to the barn. |
| Milk pickup on a fixed day | A pickup site with its own day and window, plus a pack-day sheet of exactly who's due to collect. |
| A member traveling for a week | They place a hold on their own member page. You stop setting out milk nobody's coming for. |
| Jar deposits, cream, butter, eggs for shareholders | Added as catalog items on the same account, so one balance covers the fee and the extras together. |
| Adding or removing a shareholder mid-season | Add them to the plan; their billing and pickups start from that date. No new spreadsheet tab. |

The boarding fee: bill it as a plan, not a price
The single biggest operational mistake with a herd share is treating the fee like a sale — ringing it up when the member happens to show, or waiting on a Venmo that arrives whenever. That's how you end up three months in, unsure who's current, doing math on a Sunday night.
A share plan flips it. You define the fee and the cadence once, and the plan is now the source of truth for what every member owes and when. Many farms find their fee by trial and error — starting low, realizing it doesn't cover labor, and raising it — so build yours from your real feed, labor, vet, and overhead numbers, not a neighbor's figure. If you want to reward members who commit, a prepaid cadence (a quarter or a full season at once) is a clean lever, and it smooths your own cash flow against a dairy's lumpy costs. The mechanics of seasons, cadence, and when members pay are covered in Share Plans Explained.
Dry periods and seasonal yield: the thing paper handles worst
Cows don't give the same amount of milk all year, and every cow needs a six-to-eight-week "vacation" from milking before she calves. A herd of two or three means there are real weeks when the milk is short — and your members, who own the herd, are entitled to an honest answer about what that does to their share.
You have two defensible approaches, and the right one is whichever your agreement states plainly:
- A flat year-round fee. The boarding fee covers the care of the animal, which continues whether she's milking or dry. Members accept lean weeks as the cost of owning livestock. This is the simplest to bill — the plan just keeps running.
- A pause during the dry stretch. You stop billing (and stop distributing) while production is down. This is kinder to members but demands a system that can hold a share and resume it without you reconstructing everyone's balance by hand.
Either way, what you must avoid is the third option that happens by accident: billing a flat fee, delivering short, and fielding a scatter of refund-and-credit requests one text at a time. Whether a pause, a credit, or a carry-forward is the right call — and what each does to a member's money — is exactly the decision walked through in Hold, Cancel, or Credit?
Pickup day without a clipboard
Herd-share pickups run on a tight, fixed window for a reason — raw milk is perishable and your day is full. The logistics that trip people up are always the small ones: the member who forgot their jar, the one who swears they already paid, the half-gallon left out for someone who never came.
A pickup site plus a pack-day sheet turns that into a list you can work down: who's a current member, who's due to collect today, who's on hold. Jar deposits and glass go on the same account as a catalog item, so the "I owe you for two jars" conversation is already recorded instead of remembered. And because every member has their own member page, the "am I paid up?" question answers itself without a call to you.
What this guide is not
It is not permission. A herd share can be the right structure for your farm and still be restricted or banned where you stand, and the public legal lists will not settle it for you. Confirm the rules with your state department of agriculture, get your agreement reviewed, and understand that herd health — Johne's testing, somatic cell counts, the cleanliness your shareholders are trusting you with — is an obligation that doesn't appear anywhere in this software. The tooling here handles the money and the logistics. The animals and the law are still yours.
Get the operations off paper
If the share itself is sound, the running of it shouldn't be the hard part. TallyTill's CSA and share-plan tools handle the recurring boarding fee, the balances, the pickup day, and the holds — the exact pieces a herd share turns into a spreadsheet without.
Create a free account and set up your first share plan. CSA members, share plans, and pickup sites are included on every plan, including the free Stand plan — no monthly fee and no credit card to create an account. Card sales carry a small per-sale platform fee; cash and check carry none. Current figures are on the pricing page.
