Market development funds (MDF) are budget a vendor gives a channel partner to promote the vendor product. The partner proposes an activity, the vendor approves an amount, the partner runs it, and the partner submits proof of performance to claim reimbursement. MDF is discretionary and awarded case by case. Co-op funds are the sibling model, accrued automatically as a percentage of what the partner already sold, which makes them an earned entitlement rather than a grant.

MDF is the least glamorous line in a channel budget and the one most likely to be quietly wasted. Programs allocate it, partners under-claim it, finance cannot reconcile it, and nobody can prove what it produced. This guide covers how the mechanism actually works, where MDF sits inside partner software pricing (higher than most buyers expect), and the specific steps that separate a fund program that returns pipeline from one that returns receipts.
What are market development funds?
Market development funds are money set aside by a vendor to pay for marketing that a partner performs on the vendor behalf. The partner might run a local event, a paid search campaign, a webinar, a direct mail piece, or a piece of co-branded content. The vendor does not run the activity and usually does not touch the partner audience directly. It funds the partner to reach an audience the vendor cannot reach alone.
The defining feature is that MDF is proposal-based. Funds are not automatically owed to any partner. A vendor decides which activities and which partners deserve budget, which is exactly what makes MDF a lever: it can be steered toward a new product line, a weak region, or a partner tier you are trying to grow.
MDF vs co-op funds: what is the difference?
The two get used interchangeably and they are not the same instrument. Co-op funds accrue as a fixed percentage of partner purchases or sales, typically one to three percent, and the partner earns them by selling. MDF is granted at the vendor discretion regardless of what the partner has sold. That difference changes who has leverage, how the money is accounted for, and what happens when a partner underperforms.
| Dimension | Market development funds (MDF) | Co-op funds |
|---|---|---|
| How the money is created | Vendor allocates a budget and awards it by proposal | Accrues automatically as a percentage of partner sales |
| Who decides where it goes | The vendor, activity by activity | Largely the partner, within program rules |
| Partner expectation | Discretionary. No entitlement | Earned. Partners treat it as owed |
| Best used for | New products, new regions, partners you want to grow | Rewarding and retaining already-productive partners |
| Typical failure mode | Funds go unclaimed because the process is heavy | Funds are spent on activity that would have happened anyway |
| Accounting pressure | Vendor must show the payment bought identifiable services | Accrual creates a liability the vendor carries on the books |
Plenty of programs run both. A common structure is co-op accrual for established partners plus a separate discretionary MDF pool the channel team can direct at whatever the quarter needs.
How does the MDF process work, step by step?
Six steps, and the fifth is where most programs break.
1. Allocate the pool. The vendor decides the total budget and the rules: eligible partner tiers, eligible activity types, maximum per request, claim deadline. Ambiguity here creates disputes later.
2. Partner submits a proposal. The partner describes the activity, the audience, the expected outcome, and the amount requested. Good programs require a target number, not just a plan.
3. Vendor approves or declines. Usually with a channel manager approval and a finance threshold above which someone senior signs. Speed matters more than most vendors think; a two-week approval cycle kills the local event the partner was trying to fund.
4. Partner runs the activity. Under agreed brand guidelines, using approved assets.
5. Partner submits proof of performance. Invoices, screenshots, attendee lists, campaign reports. This is the step programs underestimate. Partners hate it, submit late or incomplete evidence, and claims expire unclaimed. Unclaimed MDF looks like a saving and is really a signal that partners found the process not worth the money.
6. Vendor reimburses. Against the approved amount and the evidence, typically net 30 to net 60.
What is proof of performance in MDF?
Proof of performance is the evidence a partner submits to show an approved activity actually happened and matched what was funded. It normally combines a third-party invoice showing what was spent, artifacts of the activity itself such as the landing page, email, event photos or ad screenshots, and a results summary with leads, attendees or impressions. Vendors require it because reimbursing without evidence is both a fraud risk and an accounting problem.
How is MDF treated in accounting?
This is where a US finance team will get involved, so it is worth knowing before you design the program. Under US GAAP, consideration a vendor pays to a customer, and a reselling partner usually is a customer, is presumed to be a reduction of revenue rather than a marketing expense. The exception is when the vendor receives a distinct good or service in return and can reasonably estimate its fair value. In that case the payment can be recorded as an expense up to that fair value.
The practical consequence is that proof of performance is not bureaucratic theater. It is the documentation that supports treating MDF as marketing spend instead of a contra-revenue haircut. A program with sloppy evidence collection is not just wasting money, it is creating an audit problem. Talk to your revenue accounting team before you launch, not after the first quarter closes.
How much MDF should you budget?
There is no universal figure and anyone quoting one precisely is guessing. What is observable is the structure most programs land on: a co-op accrual in the low single-digit percentages of partner-sourced revenue, plus a discretionary MDF pool sized against a specific goal rather than a formula.
A more useful way to set the number is to work backwards from the pipeline you need. Decide what a partner-sourced opportunity is worth to you, estimate how many the activity should produce, and fund to that. Then measure. If you cannot connect funded activities to pipeline, the size of the budget is the wrong question, because you will not be able to defend any number at the next planning cycle. Getting that connection right is an attribution problem, and it is the same problem covered in partnership tracking software.
Which partner software actually includes MDF?
Buyers are routinely surprised here, so these figures were read off each vendor pricing page in August 2026. The pattern is consistent across five vendors: MDF is a premium feature, never an entry-plan one.
| Vendor | Where MDF sits | Published price |
|---|---|---|
| Magentrix | Advanced tier. Not included in Essentials | Essentials from $1,500/mo, Advanced from $3,000/mo. Annual contract; month-to-month adds 10 percent |
| ZINFI (Unifyr) | Named in the Enterprise tier alongside CPQ, rebates and rewards | Starter $1,750/mo to 100 partners, Professional $2,850/mo to 100 partners, Enterprise on request |
| PartnerStack | MDF management and payments sit in the Growth plan, not the entry Launch plan | Nothing published. Launch, Growth and Enterprise all end in a demo booking |
| Impartner | Partner Marketing Automation is a separate product from the PRM | Nothing published. Every pricing link opens a request form |
| Channelscaler (formerly Allbound) | Included within a purchased module | From $50,000 per module per year |
| Zift Solutions | Part of the channel marketing suite | No public pricing page at any obvious URL |
So the budgeting rule is that adding MDF workflow means moving up a tier or buying a second module. If MDF is a requirement, price the tier that contains it from the first conversation, or you will build a business case on a number that was never going to apply. The wider comparison of what these suites include sits on the partner marketing platform page.
Do you need MDF software, or will a spreadsheet do?
A spreadsheet plus a shared drive genuinely works up to roughly fifteen partners and a few dozen requests a year. What breaks it is not volume, it is auditability. The moment someone asks who approved a $12,000 event last March and on what evidence, an email thread is a bad answer.
Three signals say it is time for real software. Approvals are happening in email with no consistent record. Claims are expiring because partners cannot tell what evidence you want. Or finance is asking for documentation you cannot produce in a form they will accept. Any one of those costs more than a license.
Five things that make an MDF program work
Make the claim easier than the request. Most programs are the other way round, which is why funds go unclaimed. If a partner spends longer proving they spent the money than spending it, they stop asking.
Publish the rules before the quarter. Eligible activities, caps, deadlines, and what counts as proof. Partners plan marketing quarters ahead; a fund program announced in week six of the quarter buys nothing.
Require a number in the proposal. Not a plan, a target. It gives you something to measure against and it filters out partners funding activity they were doing anyway.
Tie funds to deal registration. The cleanest way to prove MDF produced revenue is to require registered deals to reference the funded activity. Deal registration is the timestamp that makes a partner claim on an opportunity defensible, which is why fund programs and registration programs work best designed together. The incentive side is covered in deal registration incentive software, and the mechanism itself in what is deal registration.
Fund partners who can actually reach your buyers. Obvious and routinely ignored. The most common way to waste MDF is to award it to whoever asks, which usually means whoever has the most channel-savvy marketing manager rather than the best audience match. Deciding that before the money moves is a research job: whose audience overlaps yours, who is adjacent rather than competing, who publishes to the buyers you want. That is the same evaluation covered in partner recruitment software, applied to partners you already have.
Common MDF questions
What does MDF stand for in channel sales? Market development funds. Some vendors write it as marketing development funds and mean the same thing. Both refer to vendor budget granted to partners for promoting the vendor product.
Who is eligible for MDF? Eligibility is set by the vendor and almost always tied to partner tier. Higher tiers get larger caps or automatic eligibility; entry-tier partners often get access only by exception. Publishing the tier rules is what makes the program a real incentive to tier up.
Can MDF be paid in cash? Not usually. MDF is reimbursement against documented spend on an approved activity, not a cash transfer. Paying it as cash removes the distinct-service argument that supports treating it as marketing expense, which is precisely what your accounting team wants to avoid.
Why do partners not claim MDF? Almost always process friction. Slow approvals, unclear evidence requirements, short claim windows, and reimbursement terms that leave a small partner out of pocket for two months. Fix the friction before you increase the budget; a bigger pool with the same process just goes unclaimed at a larger scale.
How do you measure MDF ROI? Attribute funded activities to registered deals and measure pipeline created against funds spent, not leads. Leads are easy to inflate and easy to double count when a partner runs the campaign. Pipeline tied to a registered opportunity is the number a CFO will accept.
Where to start
If you are designing a fund program from scratch, do it in this order: agree the accounting treatment with finance, write the rules and evidence requirements, then choose the software tier that actually contains MDF. Doing it in the other order is how programs end up with a platform that cannot run the process they already promised partners.
And whatever the budget, the constraint on partner marketing is rarely money. It is knowing which partners are worth funding. If the honest answer is that you fund whoever asks, the fix is upstream of the fund program: build a view of which companies reach your buyers, and how much of your reporting stack can actually connect a funded activity to closed revenue. That last part is a data-plumbing question as much as a marketing one, and teams that keep a close eye on whether their pipeline data is fresh and complete tend to be the ones who can defend the budget when planning comes round.
