Cause related advertising: tying a donation to a purchase turns the advertisement into a regulated offer, so the disclosure is part of the creative

Cause related advertising is a commercial arrangement in which what a buyer purchases determines what a charity receives. That link is the whole point and it is also the thing that changes the rules: once you say that buying from you produces a donation, you have made a factual claim about a transaction, and in much of the United States you have entered into a regulated arrangement with the charity as well. Most of the campaigns that go wrong go wrong on the same thing, which is vagueness. A portion of proceeds is not a disclosure. The amount, the recipient, the dates and the limits are, and they belong in the advertisement rather than in a footnote nobody reaches.

Three things this gets confused with

	What it is	What the buyer's purchase changes
Cause related advertising	Sales are linked to a contribution: so much per unit, or a share of the price	Everything. The donation depends on the purchase, which is why it is regulated
Sponsorship or corporate giving	You fund a charity or an event from your own budget and say so	Nothing. The gift happens whether anybody buys or not
Point of sale fundraising	You ask the customer to add a donation at the till, and pass it on	The customer donates, not you. Saying or implying otherwise is the common error here

Getting the category right decides the wording. If the money comes from your budget regardless, say so and take the credit honestly. If it comes out of a sale, the next section applies.

The five facts a donation claim has to carry

Write these into the advertisement itself, in the same type size as the offer. Each one exists because its absence is how a well meant campaign becomes a complaint.

• The amount, as a number. One dollar per unit, or ten per cent of the purchase price. A portion, a share and proceeds all mean nothing, and a buyer who later works out it was a few cents feels misled whether or not anybody broke a rule.
• Percentage of what. Ten per cent of the retail price, of the profit, or of the net after costs are three very different amounts. Say which, because a percentage of profit is a figure only you can calculate.
• The named recipient. The charity's full legal name, not a cause area. Supporting cancer research is not a recipient; a named organisation is.
• The campaign dates. Start and end. An offer with no end date is one somebody will try to claim on next year.
• Any cap or minimum. If the total donation is capped, say the cap and say it where the claim appears. A guaranteed minimum regardless of sales is worth stating too, because it is the strongest version of this claim.

A cap disclosed only in small print is the single most criticised feature of these campaigns. Once the cap is reached, further purchases produce no additional donation while the advertising continues to suggest they do, and a buyer who discovers that is right to be annoyed. State it plainly and the problem disappears.

Why this is a regulated arrangement, not just an advertisement

A business that advertises that sales will benefit a charity is, in much of the United States, acting as what state law typically calls a commercial co-venturer. The detail varies by state and the pattern does not: expect a requirement for a written agreement with the charity before the campaign runs, obligations to account to the charity for what was raised, and in some states registration, filing or a bond before you may advertise the arrangement at all. Those obligations usually attach to each state where the promotion runs rather than where you are based.

So three practical steps, in order, before any creative is approved.

• Get the written agreement with the charity first. It should name the amount, the calculation, the dates, any cap, who reports what to whom and by when, and the permission to use the charity's name and marks. Charities of any size have a standard form of this and will often have requirements of their own.
• Check the rules in every state the promotion will reach. The relevant regulator is normally the state's charity regulator or the attorney general's charities bureau, and their own pages are the source to use rather than any summary, including this one.
• Decide who holds the money and for how long. Money collected against a donation claim is not ordinary revenue, and the cleanest arrangement transfers it on a stated schedule rather than at the end of the financial year.

Separately from charity law, the advertising claim is a factual claim about your product and sits under the ordinary rules on deceptive advertising. Where a persuasive phrase becomes a claim you have to be able to support, and what has to be in hand before it runs, is set out in persuasive advertisements and where persuasion becomes a claim you have to prove.

Choosing a cause that holds up

The criticism these campaigns attract is almost always some version of the same objection: the cause has nothing to do with the business, or the business works against the cause elsewhere. Four tests, applied before the charity is approached.

• Connection. Can you explain the link in one sentence a stranger accepts? A tool company supporting a trades apprenticeship charity explains itself. A tool company supporting something unrelated invites the question of why.
• Consistency. Does anything else your business does contradict the cause? This is the test that produces the sharpest criticism when it fails, and it is checkable in advance.
• Duration. Are you prepared to do this for three years? A single campaign reads as marketing; a standing commitment reads as a position, and the second one is the only version that builds anything.
• Proportion. Is the money meaningful relative to what you spend advertising it? Spending more on the campaign than the cause receives is both the commonest shape and the hardest to defend if somebody asks.

What to measure

Use your own figures and keep two sets of them apart, because the point of this is that both should move.

• What the charity received. The total, published after the campaign, against the amount you advertised. This is the number that makes the next campaign believable, and publishing it is the cheapest trust you will ever buy.
• Units sold against the comparable period. The campaign weeks against the four weeks before and the same weeks last year, since your own seasonality will otherwise take the credit.
• Margin after the donation. A dollar per unit out of a sixty dollar margin is a decision you can make lightly. Out of a six dollar margin it is a price cut with a better story attached, and worth knowing which one you are doing.
• What happened to the people who took part. Repeat purchase rate among buyers during the campaign against your normal rate. If cause related buying produces loyalty in your category, it shows up here and nowhere else.

Resist the temptation to quote a published figure about how many consumers prefer purpose led brands. Those numbers come from surveys of stated intention, they vary enormously between studies, and your own repeat purchase rate is both more relevant and harder to argue with.

Cause related advertising: the questions that decide a campaign

What is cause related advertising?

Advertising a commercial arrangement in which the amount a charity receives depends on what customers buy. It differs from sponsorship, where you give from your own budget regardless of sales, and from point of sale fundraising, where the customer rather than the business makes the donation.

Can I say a portion of proceeds goes to charity?

It is the phrasing to avoid. It tells the buyer nothing, it is the wording that attracts complaints, and a specific figure is both easier to say and stronger as a claim. One dollar from every sale, to a named charity, between two dates, with the cap stated, is a better advertisement in every respect.

Do I need an agreement with the charity?

Yes, and get it before the campaign is advertised rather than after. State law across much of the United States treats a business advertising that sales will benefit a charity as a commercial co-venturer, with a written agreement and accounting obligations, and in some states registration or a bond before you may advertise. Read the requirements on the relevant state regulator's own pages for every state the promotion reaches.

Is a donation cap allowed?

Caps are normal and the disclosure is what matters. Put the cap where the claim is, in the same type size, and stop making the claim once the cap is reached. A campaign that keeps advertising a per purchase donation after the maximum has been hit is the clearest way to turn goodwill into a complaint.

How do I choose a charity?

Start from a connection you can explain in one sentence, check that nothing else your business does contradicts it, and ask whether you would still be doing this in three years. Then approach the charity early, because they will have their own requirements on how their name and marks are used and a standard agreement to work from.

What should I publish afterwards?

The total the charity received, the dates it covered and the date you transferred it. One short post with those three facts does more for the next campaign than the whole of the first one's advertising, because it is the only part a sceptical buyer can check.

The description of your position that you did not write

A cause campaign is a business saying what it stands for, in words it chose. There is now a place where that gets summarised by something else: a buyer asks ChatGPT, Gemini, Perplexity or Claude who to use in your category and gets back three or four companies with a sentence of description each, assembled from reviews, articles and listings rather than from your campaign. A business that has spent a year on a cause partnership and never checked whether that shows up in the summary is doing the work and missing the credit. AI Knows Us asks those buying questions across the main assistants and records who gets named and what the answers were built from.
