When the milk price moves: working capital for dairy-dependent businesses

If most of your invoices go to dairy farmers, you are in the dairy business whether you milk cows or not. The farmgate milk price decides how much your clients spend, how quickly they pay and how much of your spring work turns into cash before Christmas.

This guide is for owners of established rural service businesses (agricultural contractors, farm engineering and fabrication, irrigation and effluent specialists, vets, rural merchandise, transport, builders and electricians) who want to plan working capital around the milk price rather than react to it.

Where does the milk price stand for 2026/27?

On 21 September 2026 Fonterra revised its 2026/27 forecast, lifting the midpoint from $9.25 to $9.50 per kgMS and narrowing the range to $8.50 to $10.50. The company pointed to firmer Global Dairy Trade results for whole milk powder and skim milk powder, while warning that “geopolitical volatility remains”.

The backdrop is strong. The Ministry for Primary Industries’ June 2026 Situation and Outlook for Primary Industries expected dairy export revenue to rise 5% to a record $28.6 billion in the year to 30 June 2026.

So why plan for trouble? Because the range is $2 per kgMS wide, the season is only a few months old, and the forecast moved down in July before it moved up in September. The midpoint is not a promise. For a business whose debtors are farmers, the gap between the top and bottom of that range is the difference between a comfortable summer and an overdraft at its limit in February.

How does a forecast change reach your debtors ledger?

The link is faster than most owners expect.

Farmers are paid an advance, not the full price. Fonterra’s advance rate is the percentage of the forecast price paid each month on the milk collected. The balance arrives in later months, with a final payment after the annual results. When the forecast falls, the next monthly payment falls with it.

Farm cash peaks after your busiest billing. Spring is when calving, pasture renovation, maintenance and contracting work pile up. Your invoices go out in September to December; the farmer’s cash builds gradually across the season. Even in a good year, many farm businesses carry suppliers through spring.

Suppliers are the flexible creditor. Bank repayments, staff wages and tax are hard to delay. A trade account with the local contractor is not. When a farmer needs to stretch, it is often your invoice that waits.

Discretionary work stops first. New sheds, effluent upgrades, races, fencing and cosmetic repairs are deferred when the outlook softens. Your order book shrinks at the same time as your debtors lengthen, which is the combination that strains working capital.

Which three numbers should you know before the spring peak?

You don’t need an economist. You need three figures from your own accounts.

1. Customer concentration

What share of revenue comes from dairy clients, and what share from your top ten clients? A business with 70% of turnover from dairy, and three clients making up a quarter of it, is far more exposed than one serving dairy, sheep and beef, horticulture and lifestyle blocks.

2. Debtor days by farm, not just overall

An average can hide the problem. Run your aged debtors report by client and look for farms that used to pay on the 20th of the following month and are now drifting to 45 or 60 days. Those accounts usually move before the rest. Our debtor management guide covers how to tighten collection without damaging relationships you have built over years.

3. The cost of carrying your peak

Work out how much cash is tied up at the top of your season: wages and subcontractors paid weekly or fortnightly, fuel, parts and stock bought on 20th-of-the-month terms, and machinery repayments, set against receipts that arrive one to three months later. That figure is the working capital you need, and it grows if farm payments slow. The working capital ratio guide shows how to calculate your cash conversion cycle.

How do you model the low end of the range?

Take your 13-week cash flow forecast and run it twice.

The low-end case is not a prediction. It is a stress test. If the lowest balance in that forecast still sits inside your facility limit with room to spare, you are well placed. If it breaches the limit, you have found the problem in October rather than in March.

Don’t forget the tax calendar. GST, PAYE and provisional tax fall due on fixed dates whether or not your clients have paid. A business that accounts for GST on the invoice basis pays GST on spring invoices before the farmer settles them.

What practical steps protect cash in a dairy-dependent business?

Review terms before the busy season. Large jobs can carry a deposit or progress claims. New clients can start on shorter terms until they have a track record.

Invoice the day the job finishes. Farm work often gets invoiced in a batch at month-end. Moving to job-completion invoicing can bring receipts forward by weeks.

Protect goods you supply on credit. Where you supply equipment, parts or materials on account, retention-of-title terms registered on the Personal Property Securities Register give you a stronger position if a client fails. Ask your lawyer to check your terms of trade.

Watch for early warning signs. Part-payments, requests to split invoices, a new accountant or farm manager, or a farm listed for sale are all reasons to talk to the client early.

Know your GST position on bad debts. If a debt does go bad and you use the invoice basis, Inland Revenue lets you claim a credit adjustment of 3/23 of the amount written off, in the period you write it off.

Line up funding while your numbers are strong. Lenders assess what they can see. Accounts from a record season, with debtors still paying well, present better than accounts from the middle of a downturn.

If your spring peak is already stretching the overdraft, a 60-second enquiry is a quick way to see what working capital options fit your season.

A worked example

Illustrative scenario only. Not a client.

A Waikato agricultural contracting and farm engineering business employs 16 staff and turns over about $4.5m. Around 65% of revenue comes from roughly 80 dairy clients. Trade customers are on 20th-of-the-month terms and historically pay in about 40 days.

The owner builds a 13-week forecast from October:

• Base case: spring invoicing peaks at about $600k a month in October and November. The bank overdraft dips to within $60k of its limit in late November, then recovers as December and January receipts land.
• Low-end case: dairy debtor days stretch to 65, a third of quoted shed and effluent work is deferred, and one client owing $45k enters receivership. The forecast now breaches the overdraft limit for seven weeks from mid-November, peaking about $180k over.

The business is profitable in both cases. The issue is timing: the payroll, fuel and parts bills arrive weekly, while farm payments stretch into the new year.

The owner takes three steps. Deposits are introduced on fabrication jobs above $20k. Invoicing moves from month-end batches to job completion. And a separate working capital facility of $250k is arranged in October, secured on a rental property, with the existing bank overdraft left in place. The low-end case never fully arrives, but two large clients do slow down, and the facility is drawn for six weeks over summer instead of the business leaning on suppliers and IRD.

How do lenders look at dairy exposure?

A lender looking at a rural service business will usually want to understand:

• revenue by sector and the size of your largest clients;
• aged debtors, ideally compared with the same month a year earlier;
• how the business traded through a softer season, such as when the milk price fell sharply in the past;
• management accounts and a forecast that shows you have thought about the downside.

None of this is unusual. Dairy-servicing businesses in the Waikato, Taranaki and Southland borrow successfully all the time. The ones that get the best result arrive with the numbers already done.

For seasonal swings, a revolving facility often fits better than a term loan, because you draw it at the peak and repay it as farm payments come in. Our pages on working capital finance, unsecured loans and lines of credit and funding seasonal peaks explain the structures. Funding runs from $20k to $1m, unsecured or secured on property, and property-secured funding can settle within 24 hours of approval in some cases.

Spring is busy. Check your cash cover now

You know your farmers, your season and roughly where your overdraft will sit by Christmas. If the low-end case in your forecast shows a gap, the time to cover it is before the invoices go out, not when the first big account slips past 60 days.
