What it includes: discovery, design, building the app, keeping each customer's data separate (multi-tenancy), subscription billing, hosting, and maintenance after launch. Many quotes cover only some of these, so check which.
How providers charge: a fixed price for a defined project, time and materials (hourly), a dedicated team billed monthly, or a flat-fee development subscription. Rates run from about $24 to $49 an hour for many listed firms to $125 or more for senior North American developers.
How to choose: ask the three questions below, look at a live SaaS product they built, and start with a small paid piece of work.
SaaS Development Services at a Glance
| How you buy it | How it is priced | Best for | Watch out for |
|---|---|---|---|
| Fixed price project | One quote for a defined scope | A small, clearly defined first version | Every change becomes a change request |
| Time and materials | Hourly or daily rate | A product still changing as you learn | No cost ceiling unless you set one |
| Dedicated team | Monthly rate per person | A large product with months of full-time work | You manage the team's priorities |
| Development subscription | Flat monthly fee, requests one at a time | New builds and live products alike; big projects are broken into pieces | One request at a time, not a team working in parallel |
| Freelancer | Hourly | One well-defined feature, if you can review code | You do all the vetting |
Before you sign, ask every provider these three questions:
- Question 1, "How do you keep one customer's data away from another's?" A good answer covers the database and the server, not just the login. AWS's SaaS guidance says getting past a login does not mean a SaaS app has achieved isolation.
- Question 2, "What happens to a customer's access when their payment fails or they change plans?" A good answer names the payment events they handle and when access changes. Stripe's docs say to grant access once the invoice is paid and revoke it when a customer cancels.
- Question 3, "Who will write the code, and who owns it and the accounts?" You want named people, and the code, hosting, domain and payment accounts in your company's name.
Then start small: a paid first piece of work, in a code repository your company owns, before you commit to the whole build.
Need SaaS features shipped without an agency?
A senior developer on subscription: $2,995 a month, as many requests as you like, each shipped within 2 to 3 business days, and your money back if the first 14 days don’t prove it.

This guide is about choosing a provider. For what the whole build and its running costs add up to, see SaaS development cost. For a list of firms grouped by type, see the best product development companies. If you would rather hire one person, see how to hire a SaaS developer.
What SaaS Development Services Include
SaaS has problems a regular website does not: many customers sharing one app, recurring billing, and an app that has to stay up because every customer depends on it at once. A full service covers all of it.
Discovery and scope
Working out the first version: who it is for, the one workflow it must do well, and what can wait. Good providers push to cut scope here, not add to it.
Design
Screens and flows, usually in Figma, before or alongside the build. Some providers include a designer; many do not.
Front end, back end and database
The app itself: what users see, the server code and APIs behind it, and the database.
Multi-tenancy
Keeping each customer's data separate while they share one app. AWS warns that a user can be logged in and authorized and still reach another tenant's resources if isolation is missing.
Subscription billing
Plans, trials, upgrades, failed payments and cancellations, usually with Stripe. Each one changes what a customer can use.
Hosting and deployment
Getting it live, keeping secrets out of the code, monitoring, backups and rollbacks.
Maintenance and the backlog
Fixes, upgrades and new features after launch, which is where most of the work in a SaaS product ends up. See software maintenance services.
How SaaS Development Providers Charge
The pricing model shapes the whole relationship more than the hourly rate does.
Fixed price
One price for a defined scope. Predictable, but the scope has to be written down in detail first, and changes along the way cost extra. It fits a small first version better than a product that will evolve with customer feedback.
Time and materials
You pay for the hours worked. Flexible when priorities change, which they do in SaaS, but the bill has no ceiling unless you set a monthly cap.
Dedicated team
A group of developers assigned to your product, billed monthly per person. It suits long engagements with a lot of work, and you or a manager on your side direct what they do.
Development subscription
A flat monthly fee for a queue of requests worked one at a time. The cost is fixed and the scope can change every week. A big build is broken into smaller pieces that ship one after another, so it fits a new product as well as steady work after launch.
The gap between those rates is mostly location and seniority. Clutch says its figures come from reviews by verified clients of the firms it lists, wherever they are based. For a full breakdown of what a build, hosting and the backlog cost, see SaaS development cost.
How to Choose a SaaS Development Provider
What to check before you sign
- They can show you a live SaaS product they built, with paying customers, not just a design portfolio.
- They answer the tenant isolation and billing questions above in specifics.
- You know who will write the code, and you can talk to that person.
- The contract assigns the code to your company, and your company owns the repository, hosting, domain and payment accounts.
- The quote says what happens after launch: maintenance, fixes and new features, and what they cost.
- They will start with a small paid piece of work before the full commitment.
Which Option Should You Choose?
Predictable cost for a defined scope. Plan who will maintain and extend it after the project ends.
Flexible and scalable. Set a monthly cap and keep someone on your side directing the work.
A flat monthly fee and requests worked one at a time. Big projects are broken into pieces that ship in days, and the scope can change every week.
The cheapest way to get a single piece built. You do the vetting.
How StackTie Fits
StackTie is a development subscription for SaaS founders. One senior developer, Michael, works through your requests one at a time, including billing, permissions and keeping customers' data apart, and you get each one back in days as a pull request with a plain-English summary. You own all the code, and there is a money-back guarantee if it is not a fit. Big projects are welcome: they are broken into smaller requests and shipped in pieces. It is not the right fit if you need native iOS or Android apps, a full design team, or several people working in parallel to hit a fixed date. The price and what is included are on the homepage.
