Agencies build recurring revenue by selling things clients keep using and keep needing help with. A custom app for a local service business fits that well: the team uses it every day, the business keeps changing, and someone has to keep the app current. Charge a monthly fee for hosting, support and improvements, and each new client adds to a base of income instead of a one-time spike.
Why one-off projects keep agencies stuck
Project work has a familiar pattern. You win a website, deliver it, invoice it, and start hunting for the next one. Revenue goes up and down with your sales pipeline. A slow month for sales becomes a slow month for income.
Monthly retainers for things like SEO and social posts used to smooth that out. AI tools are putting pressure on many of those retainers because clients can now produce passable content themselves. We go into that in how AI is changing the agency business.
The fix is not to chase more projects. It is to sell something with a natural reason to pay every month.
Why apps make good recurring revenue
A website is mostly finished on launch day. An app that runs a business is never quite finished, because the business keeps moving.
| Website retainer | App retainer |
|---|---|
| Client rarely logs in | Client's team uses it daily |
| Hard to show what the fee pays for | Every change is visible to the people who asked for it |
| Easy to cancel when budgets tighten | Canceling means changing how the whole team works |
| Value fades over time | Value grows as the app fits better |
Things that create steady, real change requests in a service business:
- New staff who need access and training.
- A new service line, like a landscaper adding snow removal.
- A new step in the job flow, like photos before and after each job.
- New reports the owner wants once they see their data in one place.
- Seasonal changes in how they schedule crews.
Each one is a reason the client is glad to pay you.
Structure the monthly fee
Keep it simple. A monthly fee for a client app usually bundles:
- Hosting and running the app. With Alori, hosting, database, sign-in and SSL are handled, so this part is mostly about covering your own tooling cost.
- Support. Answering questions from the owner and staff, within set hours.
- Changes. A clear amount of small and medium changes each month.
- A regular check-in. A short monthly or quarterly call to plan improvements.
Example in USD only: a $2,500 setup fee and a $350 monthly fee for a small cleaning company. Adjust to your market and the client's size. For more models, see how to price custom apps for clients.
Do the math on a small client base
Recurring revenue adds up because it stacks. Here is a hypothetical:
Say you run a 3-person web agency. You sign two new app clients a month at an example fee of $350 a month each, and you keep them.
| Month | Active app clients | Example monthly recurring revenue |
|---|---|---|
| 3 | 6 | $2,100 |
| 6 | 12 | $4,200 |
| 12 | 24 | $8,400 |
That is before setup fees and larger change requests. Real numbers depend on your prices, your close rate and how many clients stay. The point is the shape: steady growth instead of a reset every month.
Keep clients for years
Recurring revenue only works if clients stay. What keeps them:
- Fast, safe changes. When the owner asks for something, it shows up quickly. In Alori, changes are tried on a copy first, the team keeps working in the live app, and you publish when it is ready. You can go back to an earlier version if something is off.
- Proactive ideas. Don't wait for requests. In each check-in, suggest one improvement based on how they use the app.
- Clear reporting. Send a short monthly note: what changed, what is next, anything you noticed.
- Being reachable. Local owners value a real person who answers.

Run many clients without chaos
Twenty clients on retainer means twenty sets of requests. Organize from the start:
- One project per client. In Alori, one account can hold many projects. Each project is a separate app with its own data and its own team, so client data never mixes.
- Invite the client's staff to their own project, so they log in to their app and nothing else.
- A simple request log per client: date, request, status, whether it counted toward the monthly limit.
- A publishing routine. For example, bundle small changes and publish them once a week unless something is urgent.
Grow revenue per client
Once a client trusts you, there are natural ways to grow the account without pushing:
- Move them to a higher service level when their requests grow.
- Quote larger changes, like a new area of the business, as small projects.
- Add a second app for a related business the owner runs, as its own project.
- Offer training sessions when they hire.
Grow by solving real problems. Upsells that don't help the client shorten the relationship.
Frequently asked questions
What is a good recurring revenue model for a small agency?
A setup fee plus a monthly fee for something the client uses every day is a solid model. Custom apps for service businesses fit well because they need ongoing support and changes. Define what the monthly fee includes so both sides know what to expect.
How do I convert existing website clients to monthly app retainers?
Start with clients who complain about their tools or paperwork. Build a quick demo of their business, show it, and offer it as an addition to the website, not a replacement. Clients who already trust you are the easiest to convert.
What if a client wants to stop paying the monthly fee?
Agree on this in the contract before it happens. Spell out notice periods and what happens to the app and its data. A fair exit policy makes clients more comfortable signing in the first place.
How many app clients can one person support?
It depends on how many changes each client asks for and how organized you are. Set monthly change limits, batch your publishing and keep a request log per client. Track your hours for the first few clients to find your own number.
