How to Sell Mobile Apps to Your Existing Agency Clients

Agencies providing B2B services are in a unique position to capitalize on the high demand for mobile apps. Rather than trying to acquire new leads from scratch, you can simply tap into your existing client list and sell them app development services. 

You’ve already done the hard work that’s required to land these clients. Now it’s time to extract maximum value by providing them with additional solutions that their businesses need to grow.

Digital marketing agencies, advertising agencies, PR firms, web design and development businesses, social media agencies, consultants—really any B2B agency can sell mobile apps to their existing clients. 

Key Takeaways

  • Leverage Existing Relationships: Sell to current clients to maximize value without the high cost of new lead acquisition.
  • Use White-Label Platforms: Utilize no-code reseller platforms like Buildfire to offer app development without hiring a technical team.
  • Target High-Value Segments: Focus on active clients in mobile-heavy industries like retail, fitness, and restaurants.
  • Address Objections Proactively: Counter concerns about cost and technical skills by offering affordable monthly rates and managed services.
  • Drive Recurring Revenue: Increase client lifetime value through ongoing maintenance fees and post-launch feature upsells.

Find a Platform That Simplifies Your App Development Process

The very first thing you need to do is figure out exactly how you’re going to build mobile apps for your clients. Using a white label reseller platform is by far the easiest and most profitable approach here.

With Buildfire’s reseller program, any agency can start creating and selling mobile apps without writing code or hiring a development team. 

This allows you to get your share of the $252.89 billion mobile app market without sacrificing your core agency services. You can continue doing what you do best without having to hire a new team just to manage your mobile app department. 

Unless your clients are trying to build the next Facebook or Uber, it’s highly unlikely that they’ll need custom coding. So you can just white label an app builder, create what they need using a drag-and-drop editor, and then sell apps for high profits. 

You can unlock Buildfire’s reseller program for a low fee and rebrand everything as your own. So your clients will never know the difference, and you’ll have access to the exact same platform that’s been used to create and launch over 10,000+ successful apps.

Identify High-Value Opportunities in Your Client Base 

Targeting clients with bigger budgets is often the first thing that comes to mind whenever agencies enter the app development space. While you obviously want to make sure you’re pitching to clients who can afford an app, this isn’t the only way to identify high-value opportunities.

First, start with active clients or ones that just finished a contract. This will be much easier than reaching out to a former client you haven’t spoken to in years.

Then narrow that list down to the clients to whom you’ve successfully delivered positive results with other services. From there:

  • Focus on industries where mobile apps provide clear value (retail, restaurant, fitness, education, etc.).
  • Prioritize brands whose competitors have already launched mobile apps. 
  • See if any of your clients are already getting significant site traffic from mobile devices. 
  • Consider clients who have previously indicated problems with operational inefficiencies.
  • Target clients seeking ways to improve customer loyalty, streamline bookings, or any other clear initiative that can be solved with an app.

Here’s something else to consider. Don’t ignore clients who already have a mobile app.

Download their app and see if it’s useful or delivering on its promise. If not, you can still pitch those clients and offer to build them an app that actually works. 

In these early stages, you should focus on 5-10 high-value clients. You can always scale your app development services down the road, but the first few apps will build a solid foundation for everything else.

Develop a Compelling Value Proposition

Why should clients use your agency to build their mobile app? 

This is not a rhetorical question. After all, there are other app development agencies out there who have been building apps for years. And right now, you’ve (probably) built zero apps. 

So you need to have a clear and concise value proposition that conveys:

  • You already know their brand.
  • You already know about their customers.
  • You understand their pain points. 
  • You offer everything under one roof (app development and your other services).

The reason why businesses turn to an agency for anything is because they want access to talent, expertise, and resources that they don’t already have in-house.

You can position your app development service the same way. Your clients need an app—they can’t build it themselves, and they already have an existing relationship with you. 

If you’re using a white label app builder like Buildfire, your service can also be offered at a fraction of the cost compared to traditional development. Since the platform is so affordable, you can pass those savings along to your clients while still charging enough to generate high profit margins. 

Create a Sales Pitch to Specifically Target Existing Clients

One benefit of starting with a shorter list of hand-picked clients is that you can make your sales pitches ultra-specific. This will be totally different from your normal sales calls where you’re speaking to new leads.

You already have a point of contact and an open line of communication with your existing clients. So it’s less about pitching your agency and explaining what you can do and more about adding value or solving problems.

Don’t make this a broad pitch of, “We sell mobile apps.”

Instead, leverage your existing relationship and results as much as possible. 

Your sales pitch should be centered on “When working on [whatever service you provide], we noticed [a specific problem]. We can create a mobile app for you that [solves this problem].”

Early on, you may even consider offering some type of exclusive discount to your clients who are among the first to use your app development services. 

It’s a win-win for both of you. You’ll get to sharpen your skills and have a proof of concept for marketing purposes down the road—and your clients can get an even better deal.

Prepare to Overcome Common Client Objections

Not every client you pitch is going to welcome the suggestion with open arms. That’s to be expected. But you should still be prepared to answer some of the most common objections associated with app development. Examples include:

Objection Strategy to Overcome
Cost Bust the myth of expensive development by offering affordable monthly rates ($500–$1,500) instead of large upfront fees.
Technology Explain that your agency handles all technical aspects (launch, maintenance) using a no-code app builder.
Leadership Approval Focus on ROI and specific business metrics to convince decision-makers of the app’s value.
Resistance to Change Position the app as a necessary competitive advantage to prevent falling behind industry peers.

Having the right answer ready to a common objection could potentially turn into a sale with a client who was previously on the fence.
