Co-op in one paragraph
Microsoft co-op funds are marketing dollars a US partner earns as a rebate on qualifying revenue. You accrue a percentage into a co-op balance in Partner Center, propose marketing activities against Microsoft's approved categories, execute the activity, then submit proof of execution to claim the money back. Miss any step in that chain and the fund expires unused.
Co-op sits inside the broader Microsoft Commerce Incentives (MCI) program alongside rebates and other levers. In the US market, co-op is usually the fastest way to fund demand generation, events, digital campaigns and content - if you treat it like a marketing budget instead of an admin task.
The US co-op funding cycle, end to end
This is the loop that partners who consistently spend 100% of their co-op run every half.
1. Earn
Co-op accrues based on qualifying billed revenue in the incentive categories you're enrolled in. Balances update in Partner Center. Check your accrual rate and category eligibility at the start of each Microsoft fiscal (July 1).
2. Plan
Map the balance to a marketing plan aligned with a Microsoft solution area and a US buyer motion - Copilot, Azure migration, security modernization, industry cloud. Approved categories include digital marketing, events, telemarketing, content syndication, training and more.
3. Pre-approve
Submit the activity in Partner Center with dates, description, vendor and estimated cost. Get pre-approval before spending. Retro-claims after the fact are the #1 reason US partners lose funds.
4. Execute
Run the activity through an eligible third-party vendor (a US-based agency, publisher or event partner). Keep dated invoices, campaign screenshots, attendee lists, click-through data and creative assets from day one.
5. Claim
Submit proof of execution inside Microsoft's claim window - typically 60 days after activity end. Include the invoice, a claim narrative, and proof matching Microsoft's category requirements. Late or thin claims get rejected.
6. Reconcile
Track approved vs paid vs remaining balance monthly. Reforecast the second half of the year against unspent funds so nothing expires at fiscal year-end.
What US partners can actually spend co-op on
The eligible category list is broad but specific. In the US the most-used categories are: digital marketing (paid search, paid social, programmatic, SEO content production), events (proprietary, third-party, executive round-tables), telemarketing and appointment-setting, content syndication with approved publishers, training and readiness for customers, and creative development for co-branded assets.
Ineligible spend includes internal salaries, general overhead, hospitality-only entertainment, hardware and anything without a clear marketing outcome. If it wouldn't survive a Microsoft auditor's raised eyebrow, don't claim it.
Proof of execution: the part that trips people up
US claims are rejected far more often on proof quality than on activity choice. Microsoft wants to see the activity happened, that it was on-brand and category-compliant, and that the invoice matches the pre-approval.
For a paid campaign that means the creative, the platform screenshot, the flight dates, the audience definition and the invoice. For an event it means the agenda, the attendee list, photos, the invoice and (where relevant) MSUS speaker sign-off. Build a proof pack template for each category once and reuse it - it turns claims from a scramble into a checklist.
Five moves that get more co-op spent and approved
Plan against the Microsoft US fiscal
Break your co-op balance into H1 (Jul-Dec) and H2 (Jan-Jun) allocations and lock the plan by early Q1. Waiting until Q4 to spend is how funds expire.
Run activities in bigger blocks
One well-run US webinar series claims cleaner than five tiny tactics. Bigger blocks also produce stronger proof of execution.
Use approved vendors from day one
Third-party invoices are the backbone of every claim. Working with a US-based agency that already knows Microsoft's proof requirements removes half the risk.
Tie every activity to a solution area
Microsoft wants to see co-op fueling the solution areas they're pushing. Copilot, Azure, security and industry cloud campaigns get through review faster than generic brand work.
Reforecast every 60 days
Balances change as revenue earns more accrual. A quarterly reforecast catches unspent funds while there's still time to redeploy them.
