Co-op advertising funds and market development funds (MDF) are both ways a brand pays its partners to market its products. The difference is mainly in how the money is earned and what it can be spent on. Co-op funds are usually earned by the partner as a share of its purchases and reimburse advertising that features the brand. MDF is usually allocated by the brand, often based on a proposed plan, and can fund a broader range of activities: events, training, campaigns and entering new markets.

Side by side
| Co-op advertising funds | Market development funds (MDF) | |
|---|---|---|
| How they’re earned | Usually accrued as a share of the partner’s purchases | Usually allocated by the brand, often against a proposal |
| Who decides | Partner spends within program rules | Brand approves each plan or activity |
| Typical uses | Advertising featuring the brand: search, social, print, radio, email | Broader: events, training, demos, campaigns, new-market entry |
| Timing | Partner advertises, then claims reimbursement | Often pre-approved before the activity |
| Common in | Consumer goods, electronics, sporting goods, home improvement, automotive | Technology and software channel programs, B2B distribution |
| Proof required | Proof of performance: invoices, screenshots, tear sheets | Activity report and results |
The labels aren’t used consistently. Some brands call everything “co-op”, others call everything “MDF”, and many programs combine both. The program terms matter more than the name.
How MDF works
- Allocation. The brand sets aside funds for partners, often based on partner tier, past performance or strategic priority.
- Proposal. The partner proposes an activity: a campaign, an event, a training program.
- Pre-approval. The brand approves the plan, budget and often the creative.
- Execution. The partner runs the activity.
- Claim and proof. The partner submits proof and results; the brand reimburses or pays as agreed.
Which one fits which situation
Co-op fits when a brand wants many partners to advertise its products continuously, with simple rules and minimal approval overhead. It scales across hundreds of retailers.
MDF fits when a brand wants specific activities from specific partners: a launch in a new market, a joint event, a strategic campaign. It’s more controlled and more work for both sides.
The brand risk in both
In both models, the brand pays for marketing that partners write. The partner usually advertises many brands at once, under time pressure, judged on its own sales. Unless the brand’s guidelines are clear and checked, the result is often advertising that features the brand but doesn’t represent it: discount-led headlines, generic template copy, the brand as one keyword among many.
In our benchmark of premium multi-brand retailers’ Google Ads, 42% of headlines led with a discount and only 21% said anything about the brands being sold. Some of that advertising may well have been co-funded by the brands themselves.
Practical safeguards for either model:
- Advertising guidelines specific enough to check: required messages, prohibited framings, how prices may appear. See co-op advertising guidelines.
- Reimbursement tied to meeting the guidelines, not only to proof that the ad ran.
- A way to see what partners actually publish, before or soon after it runs.
FAQ
What is the difference between co-op advertising and MDF?
Co-op funds are typically earned by partners as a share of their purchases and reimburse advertising that features the brand. Market development funds are typically allocated by the brand, often against a proposed plan, and can fund broader activities such as events, training and new-market campaigns.
What are market development funds?
Market development funds (MDF) are budgets a brand or manufacturer provides to its channel partners to fund marketing and sales activities that grow demand for the brand’s products, usually approved in advance.
What can MDF be used for?
Common uses include advertising campaigns, events and trade shows, product demos, partner sales training, content and market-entry activities. The program terms define what’s eligible.
Is MDF the same as co-op?
Not exactly, though the terms are often used interchangeably and many programs combine both. Co-op is usually accrual-based and advertising-focused; MDF is usually allocation-based and covers wider activities.
How do brands make sure partner advertising stays on brand?
By setting checkable advertising guidelines, linking reimbursement to compliance with those guidelines, and reviewing what partners actually publish.
