When your mobile measurement partner (MMP) contract comes up for renewal, it’s worth pausing before you auto-renew. The right moment to ask hard questions is before you sign, not after. Whether you’re running on Adjust, AppsFlyer, or another platform, a renewal is a practical opportunity to audit your current setup, compare app attribution tools, and make sure you’re still getting value. These six questions will help you do exactly that.
What’s really at stake when your MMP contract ends
Many teams inherit a tracking setup that was configured years ago, sometimes by a previous agency or a developer who has long since moved on. An outdated app tracking setup can quietly distort your data, inflate your costs, and leave you blind to what’s actually driving installs and in-app events. The contract renewal moment is one of the few times you have real leverage to fix this.
Before you renew, it helps to treat your current MMP relationship like any other vendor relationship: does it still serve your goals? The app measurement market has changed significantly, and what made sense two or three years ago may no longer match your current scale, stack, or strategy. Taking a structured approach to your app tracking audit now will save you time, money, and data headaches later.
1: Are you actually using all the features you’re paying for?
Most MMP contracts include a broad feature set, but the majority of teams regularly use only a fraction of what they pay for. Deep linking, audience segmentation, custom dashboards, and cohort analysis tools often go untouched, yet they’re bundled into your annual fee.
Before renewing, pull a list of every feature your current plan includes and honestly assess usage over the past twelve months. If large parts of the platform are collecting dust, you may be over-tiered. Equally, if you’ve been working around missing functionality, it might be time to right-size your app tools or switch app measurement tools entirely.
This is a straightforward audit that takes a few hours but can surface meaningful savings or highlight a genuine capability gap. It’s worth doing before any renewal conversation starts.
2: How accurate is your attribution data?
Attribution accuracy is the foundation of every paid campaign decision you make. If your MMP is misattributing installs, over-counting organic, or struggling with iOS post-ATT measurement, you’re optimising based on flawed signals.
Check whether your platform has kept pace with Apple’s privacy framework updates and Google’s evolving attribution requirements. Ask your vendor directly how they handle SKAdNetwork discrepancies and probabilistic modelling gaps. If their answers are vague or their documentation is outdated, that’s a signal worth taking seriously.
An Adjust implementation or AppsFlyer setup that was configured before major privacy changes may need a full reconfiguration, not just a renewal. Accurate data is what separates efficient spending from wasted budget.
3: Does the pricing model still match your growth stage?
MMP pricing typically scales with monthly active users (MAUs) or attributed events. If your app has grown significantly, you may have moved into a higher pricing tier without a corresponding increase in value. Conversely, if growth has plateaued, you might be paying for volume headroom you don’t need.
When comparing app attribution tools, look beyond the headline price. Consider the cost per attributed event, the flexibility of the contract structure, and whether there are overage charges that could hit you during seasonal peaks. Some vendors offer more predictable pricing for apps at specific growth stages, so it pays to get quotes from alternatives before committing to a renewal.
4: What integrations does your stack actually need?
Your MMP sits at the centre of your measurement stack, connecting your ad networks, analytics tools, CRM, and data warehouse. If your stack has evolved since you first set up your tracking, your integration requirements may have changed too.
Map out every integration your team actively relies on: Apple Search Ads, Google, Meta, TikTok, your BI tool, your CRM. Then check whether your current MMP supports all of them natively or whether you’re relying on workarounds and manual exports. A platform that covers your full stack cleanly will save your team significant time and reduce the risk of data gaps.
This is also the right moment to consider whether a switch to a different platform would unlock integrations that are currently blocking your workflow. The migration cost is real, but so is the ongoing cost of a poor fit.
5: How has the vendor’s fraud protection evolved?
Ad fraud remains a persistent challenge in mobile marketing, and the methods used by bad actors continue to evolve. Your MMP’s fraud protection tools should have evolved alongside them.
Ask your vendor to walk you through their current fraud detection capabilities: click injection filtering, SDK spoofing detection, install validation, and anomaly flagging. If their fraud protection toolkit looks the same as it did two years ago, that’s worth questioning. The platforms that invest consistently in fraud prevention tend to offer meaningfully better data quality over time, which directly affects your campaign performance and budget efficiency.
6: What does their support and SLA actually look like?
When something breaks in your tracking setup, the speed and quality of support you receive has a direct impact on your campaigns. A few days of misconfigured attribution during a major campaign launch can cost you significant budget.
Review your current SLA carefully. What response times are guaranteed? Is there a dedicated account manager, or are you routed through a generic support queue? Has the level of support you’ve received in practice matched what was promised at the time of signing? These are questions worth asking before you renew, not after you’ve experienced a critical issue mid-campaign.
Support quality is one of the most common points of frustration teams raise when evaluating whether to switch app measurement tools, yet it’s often overlooked during the initial vendor selection process.
Make your next contract work harder for your app
Renewing your MMP contract without asking these questions means accepting whatever you already have, including its limitations. A structured app tracking audit before renewal puts you in a much stronger position: you’ll either confirm that your current setup is genuinely the right fit, or you’ll identify the changes needed to get more from your measurement investment.
At Wuzzon, we work with apps at every growth stage to evaluate and optimise their measurement stack. Our app growth stack expertise covers everything from Adjust implementation and AppsFlyer vs. Adjust comparisons to full migration support and ongoing tracking governance. If your contract is coming up for renewal and you want a second opinion on your current setup, talk to one of our specialists before you sign anything.
Frequently Asked Questions
How long does a proper MMP audit typically take, and when should I start before my contract renewal date?
A thorough MMP audit typically takes one to two weeks when done properly, covering feature usage, attribution accuracy, integrations, and vendor comparisons. Ideally, you should start at least 60 to 90 days before your renewal date — this gives you enough time to gather internal data, request quotes from alternative platforms, and negotiate from a position of strength rather than rushing a decision under deadline pressure.
What are the biggest red flags that it's time to switch MMPs rather than renew?
The clearest signals are persistent attribution discrepancies you can’t resolve with your current vendor, lack of meaningful updates to privacy framework support (especially iOS ATT and SKAdNetwork), and a consistent gap between the support quality promised and what you actually receive. If you’re regularly working around your MMP’s limitations rather than working with it — through manual exports, spreadsheet patches, or third-party workarounds — that’s a strong sign the platform is no longer the right fit for your stack.
How difficult is it to migrate from one MMP to another, and what's the risk to live campaign data?
Migration complexity varies depending on the number of integrated ad networks, the depth of your SDK implementation, and whether you rely on deep linking or custom event schemas. Most migrations can be completed without significant data loss if planned carefully, typically running both platforms in parallel for a defined period to validate parity before fully cutting over. Working with a specialist who has handled multiple MMP migrations — rather than relying solely on the new vendor’s onboarding team — significantly reduces the risk of gaps in your attribution data during the transition.
Can I negotiate my MMP contract, or is pricing generally fixed?
MMP pricing is almost always negotiable, particularly at renewal. Vendors have strong incentives to retain existing customers, and coming to the table with competing quotes from platforms like Adjust, AppsFlyer, or Singular puts you in a genuinely strong position. Beyond headline price, you can often negotiate on contract length flexibility, overage caps, included support tiers, and onboarding credits — especially if you’re willing to commit to a longer term.
How do I know if my current SKAdNetwork and iOS attribution setup is actually working correctly?
Start by comparing your MMP’s reported iOS install volumes against what you see directly in Apple’s Ad Platforms and your ad network dashboards — significant, unexplained discrepancies are a strong indicator of a misconfiguration. You should also check whether your conversion value schema is still aligned with your current in-app events and business goals, as many setups were configured at ATT launch and have never been updated. If your MMP’s iOS reporting relies heavily on modelled data without clear documentation of how that modelling works, ask your vendor for a detailed explanation or consider an independent audit.
What's the difference between a self-serve MMP audit and working with an external specialist?
A self-serve audit is valuable for surfacing obvious gaps — unused features, basic integration checks, and pricing comparisons — but it’s limited by your team’s familiarity with what ‘good’ actually looks like across platforms. An external specialist brings cross-platform benchmarks, hands-on experience with common misconfigurations, and an objective view that isn’t influenced by internal assumptions or vendor relationships. For teams where attribution data directly drives significant ad spend, the cost of an external audit is typically recovered quickly through improved data quality and more efficient campaign decisions.
Should smaller or earlier-stage apps bother with a formal MMP audit, or is this mainly relevant for larger teams?
A formal audit is arguably more important for smaller teams, not less — because wasted budget or poor attribution data has a proportionally larger impact when resources are limited. Smaller apps are also more likely to be on a plan that was set up quickly at launch and never revisited, meaning there’s often significant room to right-size the contract or fix foundational tracking issues. Even a lightweight audit focused on pricing fit, core integration health, and iOS measurement accuracy can surface meaningful improvements without requiring significant time investment.
