Market development funds, usually called MDF, are money a vendor makes available to partners to help market the vendor’s products. Vendors fund them because partner marketing grows their business. Partners often leave a share of them unspent. The reason is rarely that the money was not wanted. It is that claiming MDF means meeting conditions, in order, on a deadline, with documents, for each vendor separately.
This post is for the partner side. The goal is to make sure the funds you are entitled to actually reach your marketing budget.
The exact terms are set by each vendor and change between programs, so check your own agreements. But most MDF programs share a common shape.
Most rejected or unclaimed MDF falls into a handful of patterns, all of them preventable with a process.
| Failure | What happens | Prevention |
| No pre-approval | The activity runs and the vendor declines to reimburse it. | Make approval a hard gate before any spend is committed. |
| Wrong activity category | The activity does not match what the fund covers. | Read the fund’s eligible-activity list before planning the campaign. |
| Weak proof of execution | The claim is submitted without the evidence the vendor requires. | Capture evidence as the activity runs, not afterwards. |
| Late submission | The claim window closes first. | Put claim deadlines on a calendar with a reminder 30 days out. |
| Fund forgotten | Nobody knew the money existed. | Keep one list of funds available across all vendors. |
| Tier slipped | A lapsed requirement reduced or removed eligibility. | Track tier status alongside the fund, not separately. |
Because every vendor runs its own portal and rules, the only way to see your total position is to keep one ledger.
| Vendor | Fund type | Allocated | Approved activity | Claim deadline | Status |
| Vendor A | Co-op | $20,000 | Webinar series | Sep 30 | Approved |
| Vendor B | Development | $12,000 | — | Dec 15 | Unplanned |
| Vendor C | Event | $8,000 | Regional event | Aug 31 | Claim due |

How much MDF a vendor offers, and how easy it is to claim, tells you something about how the vendor values partners. Include it in your vendor review. A vendor with generous funds that you cannot practically claim is delivering less than the headline suggests, and one with modest funds and a simple process may be delivering more.
A quick audit: Total the MDF you could have claimed from all vendors over the last twelve months, then total what you actually claimed. The gap is the number that justifies a process.
Marketing teams often treat MDF as a bonus that appears during the year. The firms that use it well plan the other way round: they start with the funds available and the conditions attached, then fit the marketing plan around them.
Vendors approve requests that look like marketing they want to see. A good request states the audience, the offer, the channels, the expected results, and the way the vendor’s products feature. It names the budget split, shows what you are contributing, and explains how results will be measured. Vague requests are slower to approve and easier to reject.
Funds come with a cost: the time to request, the evidence to assemble, and the constraints on what you can run. Track hours spent and dollars claimed per vendor. Some programs return a great deal for modest effort. Others consume more time than they return. That comparison belongs on the vendor scorecard, because it affects where marketing investment goes.
| Section | What to include |
| Objective | What the campaign is meant to achieve, in one sentence, with a measurable target. |
| Audience | Who you are marketing to, and why they are a fit for the vendor’s products. |
| Activities | The channels and formats, with dates. |
| Budget | Total cost, the amount requested, and your own contribution. |
| Measurement | How you will report results, such as leads, meetings, or pipeline. |
| Evidence plan | What proof of execution you will collect and when. |
Using the same outline for every request makes approvals faster, and it makes the later claim easier because the evidence plan was agreed up front.
Funds can distort planning. If an activity is only worth running because it is subsidized, and the conditions would pull your marketing away from your own priorities, consider declining. MDF should support the plan you would have made anyway, not replace it.
In many channels, funds flow through a distributor as well as, or instead of, the vendor. The rules, deadlines, and evidence requirements can differ from the vendor’s own. Ask your distributor contact which funds they administer, what they need, and how their deadlines relate to the vendor’s. Add the distributor to your ledger as a source in its own right, so that nothing is missed because it arrived through an unfamiliar door.
No. They usually depend on approval, conditions, and deadlines. Treat an allocation as an opportunity until the claim is paid.
Before committing spend. Many programs do not reimburse activities that were not approved in advance.
It depends on the vendor. Common examples are invoices, screenshots, attendee lists, and campaign reports. Ask for the checklist up front.
AltamIQ: AltamIQ keeps funds, deadlines, and tier standing for every vendor in one portfolio view, so MDF stops depending on whoever remembers to check each portal. Because tier status sits beside the fund, a slip in your standing shows up before it costs you the money.
