How much does it cost to build a SaaS product in 2026?

SaaS development cost is the question most founders ask after they have already priced "an app" and been surprised by the gap. A first working SaaS product starts at about $4,000 to $10,000 with an AI-first team, a multi-tenant product with plans, roles and integrations lands between $10,000 and $20,000, and an enterprise-ready platform runs $20,000 to $30,000 and up. A traditional agency writing the same code by hand usually charges 3 times those numbers and takes 3 times as long.
The gap between "an app" and "a SaaS" is not size. It is the handful of systems a product needs the moment strangers pay for it monthly: billing, tenancy, onboarding that works without you, and a product that keeps changing after launch.
What makes SaaS cost more than a regular web app
A web app has users. A SaaS product has customers, and every part of that sentence adds a system you have to build:
| What a web app has | What a SaaS product adds |
|---|---|
| Sign up and log in | Workspaces or organisations, invitations, roles and permissions |
| One kind of user | Plans, trials, limits per plan, upgrades and downgrades |
| A payment, maybe | Recurring billing, proration, failed payments, invoices, a billing portal |
| A demo you give | Self-serve onboarding that gets a customer to value without a call |
| A launch | Continuous releases, feature flags, and data migrations on a live system |
| Your data | Tenant isolation: one customer must never see another's data, even by accident |
Billing and tenancy are where the money goes. Everything else is recognisable work from any MVP build.
SaaS development cost by scope (AI-first, 2026)
These are our numbers, from the same 2026 price book as the rest of the site. They are low because the same working system takes fewer hours when AI writes the code and senior engineers direct it, not because the work is thinner. Traditional hand-written development typically costs 3 times as much and takes 3 times as long.
| Scope | Price | Timeline | What it includes |
|---|---|---|---|
| SaaS MVP | $4,000-10,000 | 2-4 weeks | Accounts, one core workflow, one subscription plan through Stripe, a basic admin, transactional email |
| Multi-tenant SaaS | $10,000-20,000 | 4-6 weeks | Workspaces with roles and invitations, several plans with limits, billing portal, self-serve onboarding, two or three integrations, analytics |
| Enterprise-ready SaaS | $20,000-30,000+ | 6-8 weeks | SSO, audit logs, a public API, white-label options, usage-based billing, AI features, the admin tooling to run it |
Most funded B2B startups land in the middle row. The exact figure is named after a short discovery call, because the billing model and the tenancy model change the build more than any list of features.
The two decisions that move the price most
Not the design, not the number of screens: how customers are grouped, and how they pay.
- Tenancy. One user, one account is the cheapest shape and works for consumer and prosumer tools. Workspaces with members and roles are what B2B customers expect, and they touch every screen and every database query. Decide this before the first line of code, because retrofitting workspaces into a single-user product is a rebuild, not a feature.
- Billing. One flat monthly plan is a few days of work with Stripe. Several plans with feature limits add a permissions layer. Per-seat billing adds proration whenever someone is invited or removed. Usage-based billing adds metering, which is a system of its own. Each step roughly doubles the billing work, and the first version rarely needs more than the first step.
A product that starts with workspaces and one flat plan has both decisions right for the next twelve months at close to the cheapest price.
What to cut from version one
The first version of a SaaS exists to answer one question: will a customer pay for this on the second month. These can all wait until the answer is yes:
- Usage-based billing. Start with a flat plan or per-seat pricing. Meter usage in the background if you like, but do not bill on it yet.
- SSO and audit logs. Your first enterprise customer will ask for them, and that is a good moment to build them, because the customer will be paying for the tier that includes them.
- A public API. Two integrations you build yourself beat an API nobody has asked for.
- Native mobile apps. A responsive web app reaches every customer on day one.
What you cannot cut: a working trial-to-paid flow, tenant isolation, and an admin panel for yourself. You will be onboarding customers by hand for a while, and you need to see what they do.
What a SaaS product costs to run after launch
The build is one number; a SaaS then has a monthly bill that grows with customers:
- Hosting and infrastructure: $30-300 per month for a new product, up to $800 with real traffic, background jobs and file storage.
- Payment processing: about 2.9% + $0.30 per transaction, plus roughly 0.5-0.7% for subscription billing on providers like Stripe Billing.
- Third-party services: email, authentication, error monitoring, analytics, usually $50-200 per month combined at the start.
- Maintenance and small changes: budget 5-10% of the build cost per year, or a fixed monthly retainer once the product earns.
A SaaS built for $12,000 with $300 per month in running costs and a $49 plan needs about 25 paying customers to cover its monthly bill, and about 250 customer-months to pay back the build. Both numbers are worth knowing before you start.
Why AI-first teams build SaaS 3 times cheaper
A SaaS product is mostly well-understood systems assembled carefully: auth, workspaces, billing, email, an admin, a dashboard. An AI pipeline does that work well, and a senior engineer's judgment still matters most on the parts that are expensive to get wrong in production: the data model, tenant isolation, billing edge cases. Our team writes the code with AI and keeps senior engineers on those decisions, so the same working product takes about a third of the hours. That is where 3 times cheaper and 3 times faster comes from: fewer hours, not thinner work.
What this looks like in real products
Two SaaS-shaped products from our portfolio, each solving a different part of the problem:
- Pulzio is a B2B employee-feedback platform: companies, departments, roles and invitations, a real-time dashboard, and an AI assistant that turns anonymous comments into action plans. Anonymity is enforced in the data model rather than promised in the copy, which is the tenancy problem in its hardest form.
- Sanction Finder is an enterprise compliance platform for sanctions screening, where the product claim is not the search but the freshness of the data behind it, and where buyers run a vendor assessment before they run a trial.
Frequently asked questions
How much does it cost to build a SaaS product? A first working SaaS with accounts, one core workflow, one subscription plan and a basic admin starts at about $4,000 to $10,000 with an AI-first team. Workspaces with roles, several plans, usage limits and integrations push it to $10,000 to $20,000, and an enterprise-ready platform with SSO, an API and audit logs runs $20,000 to $30,000 and up. A traditional agency writing the same code by hand usually charges 3 times these numbers.
How long does it take to build a SaaS product? A SaaS MVP takes 2 to 4 weeks with an AI-first team, a multi-tenant product with plans and roles takes 4 to 6 weeks, and an enterprise-ready platform takes 6 to 8 weeks. The same scope takes roughly 3 times as long with traditional hand-written development.
What is the difference between a SaaS product and a regular web app? A regular web app has users. A SaaS product has customers who pay every month, which adds subscription billing, plans and limits, self-serve onboarding, workspaces that keep one customer's data away from another's, and the expectation that the product keeps improving after launch. Those parts are where the extra cost sits.
How much does it cost to run a SaaS product after launch? Hosting and infrastructure run $30 to $300 per month for a new product and up to $800 with real traffic. Payment processing takes about 2.9% plus $0.30 per transaction, with a small extra fee for subscription billing. Email, auth and monitoring services add $50 to $200 per month at the start, and maintenance is worth budgeting at 5 to 10% of the build cost per year.

How much does it cost to build a marketplace in 2026?
A marketplace is not a bigger online store: it has two sides, commissions and payouts, and a trust problem. Here is what each part costs, what the first version should contain, and why most marketplaces fail on supply rather than software.

Automation platforms price per run, custom builds price once. That single difference decides which is cheaper for you. Here is the arithmetic, the three things platforms cannot do at any price, and how to work out your own crossover point.
