Which user acquisition channels should a B2B mobile app use?
A practical app for engineers, site crews or field technicians does not need millions of installs. It needs the right professionals to find it, reach a useful result, pay, and bring the app into their company. This page shows how to pick channels on that basis.
How should a work app choose its acquisition channels?
Start with channels where the person is already looking for a way to do the task: app store search, Google search for the task or tool, and colleagues who already use the app. Add interruptive channels such as paid social only once you know which users activate and pay.
Then check the numbers. A channel is affordable when the cost of one paying user is well below what that user, and the company they may bring in, is worth to you after store fees.
Two questions decide almost every channel choice. First, how close is the person to the problem right now? A site supervisor typing "daily report app" into the App Store is closer than someone scrolling a feed. Second, what is one customer worth? An app with a company plan can afford far more per user than an app that only sells individual subscriptions.
Illustrative example written by ShoutEx for this guide, not a benchmark.
How much can you afford to pay for a user?
Work backwards from revenue. Estimate what a paying user brings in after store fees, how many months they usually stay, and what share of paying users later bring in their company. Decide what share of that value you will spend to win it. The result tells you the most you can pay per install for a channel to make sense.
| Line | Individual plan only | With company accounts |
|---|---|---|
| Price | $15 per user per month | Same, plus company plan at 10 seats × $15 |
| Net per month (15% store fee assumed) | $12.75 | $12.75 individual; $150 company, invoiced directly |
| Expected paid months | 8 | 8 individual; 24 company |
| Value per paying individual | $102 | $102 + 8% × $3,600 = $390 |
| Acquisition budget at one third of value | $34 | $130 |
| Install to paying user (40% activate × 6% pay) | 2.4% | 2.4% |
| Most you can pay per install | about $0.82 | about $3.12 |
The company path almost quadruples what this app can pay per install, which opens channels such as search ads that would otherwise be too expensive. Rework the table with your own numbers in the mobile app growth calculator, and see unit economics for payback and margin.
Which channels match which buyer intent?
Sort channels by how close the person is to the task. High-intent channels cost more per click or tap but convert better; low-intent channels need stronger creative and a longer path to payment.
| Channel | Intent | What the person is doing | Fits apps that | Watch out for |
|---|---|---|---|---|
| App store search | High | Typing a task or tool name into the store | Have a clear task name | Listing work first; see App Store optimization |
| Apple Ads | High on search results | Same search, with your ad on top | Have iPhone-heavy users | Cost per tap; tie bids to activation |
| Google App campaigns | Mixed | Searching, watching or browsing across Google | Need Android reach | Automation optimizes to the event you choose |
| Search ads to a web page | High | Searching a how-to or tool problem on a laptop | Sell to company buyers | Needs a landing page; see web or store first |
| SEO and content | Medium to high | Reading an answer to a work problem | Solve searchable tasks | Months before traffic builds |
| Paid social | Low | Scrolling a feed | Show a visible before and after | Weaker attribution on iOS |
| Communities and partners | Medium, trust-led | Asking peers what they use | Serve one trade well | Slow to set up, hard to scale |
| Invites from colleagues | High | Opening a link from a co-worker | Create shared work | Only works once people activate |
Apple lists its ad placement options as the Today tab, the Search tab, search results and product pages; search results ads are charged per tap and can use a target cost per acquisition. Google's App campaigns build ads from your text, images and videos and place them across Search, Play, YouTube, Display and Discover, optimizing for installs, in-app actions or pre-registration. For tool searches on the web, a plain search ad to a focused page often reaches the person who will later buy for the team:
Log photos, weather and crew hours on site. Share a PDF with the office the same day.
Photos, weather and crew hours in one report. PDF to the office the same day.
What does the difference look like between two channels?
Here is one month of spend split across two channels for a fictional site report app. Channel A is a broad social campaign with cheap installs. Channel B is Apple Ads on task keywords, with installs that cost more than twice as much.
The trap is that Channel A looks better on every install report. Only a view that follows users to activation and payment shows that Channel B wins. That view needs tracking set up before the spend starts; see analytics and attribution.
Buy the second step, not the first.
Optimize every paid channel toward an action inside the app that predicts payment, such as a first report shared or a first calculation saved. Installs are a cost line, not a result.
What mistakes waste an acquisition budget?
- Optimizing to installs. Bidding systems find the people most likely to install, not the ones most likely to use the app at work. Send them an in-app event instead.
- Spreading a small budget thin. Five channels at $400 each teach you nothing. Two channels with enough volume to compare cost per activated user teach you a lot.
- Ignoring the company buyer. When an engineering manager asks about team pricing from inside the app, that is your most valuable lead. In the HBR study of online sales leads, firms that contacted leads within an hour were far more likely to qualify them than firms that waited.
- Paying for people who would have come anyway. Bidding on your own app name in the store can be sensible defence, but report it apart from task keywords.
- Judging too early. Company accounts often appear weeks after the first individual paid. Look at 60 to 90 day cohorts before cutting a channel.

What should you measure for user acquisition?
| Metric | Question it answers | Where to find it |
|---|---|---|
| Cost per paying account | Does the channel make money? | Ad spend plus store and billing records |
| Cost per activated user | Does it bring people who reach a useful result? | Ad spend plus your product analytics |
| Activation rate by source | Which sources bring real users? | App Store Connect sources, Play Console acquisition, analytics |
| Paying users who start a team | Does the channel feed company revenue? | Billing system or CRM |
| Reply time on company enquiries | Do hot leads go cold? | CRM or shared inbox |
| Payback month | When does spend come back? | Your model or the growth calculator |

Frequently asked questions
What is the cheapest way to acquire users for a B2B app?
Usually app store search and invites from existing users, because the person already wants the task done or trusts the colleague who sent the link. They are cheap per user but slow to scale.
Should a B2B mobile app run paid ads at launch?
Run a small, focused test on high-intent searches once onboarding works and tracking is in place. Scale only after you can see cost per activated and paying user.
Is cost per install a useful metric?
Only as an input. A low cost per install is meaningless if those users never reach a useful result or pay.
Apple Ads or Google App campaigns first?
Follow your users. If most of your target professionals carry iPhones, start with Apple Ads on task keywords; if your trade is Android-heavy, start with Google App campaigns optimized to an in-app event.
How much should I spend on acquisition per user?
Work it out from revenue: value of a paying user after store fees, times the share you will spend, times your install to paid rate. The company plan usually changes the answer most.
When should I judge a new channel?
After enough users have had time to activate and pay, often 60 to 90 days for a work app. Look at cohorts by start month rather than a single blended total.
Do downloads help app store ranking?
Store search uses user behaviour among its signals, but downloads that never turn into active users do not help the business. Grow installs that activate.
How fast should we answer a team pricing enquiry?
Within the hour where you can. Research on online leads found that quick contact made qualification far more likely.
