A SaaS development company designs, builds and maintains subscription software for you: user accounts, a multi-tenant architecture that keeps each customer's data separate, subscription billing, admin tools and an API. Wix Engine works with founders validating an MVP and with established businesses turning an internal tool or service into a product they can sell.
From the first sign-up screen to the super-admin console, these are the parts every SaaS product needs, and the ones we build.
The smallest product that proves customers will pay. We run a scoping workshop to separate must-haves from nice-to-haves, then build one core workflow really well, with sign-up, billing and an admin view included. You launch with something real to sell, not a demo.
Multi-tenant SaaS development gives every customer organization its own isolated data space. Depending on your customers and compliance needs, we use a shared database with tenant IDs and PostgreSQL row-level security, a schema per tenant, or a database per tenant. We decide this before development starts, because changing it later is expensive.
Plans, free trials, per-seat and usage-based pricing, coupons, proration on upgrades, invoices and a self-service customer portal, all through Stripe Billing. Stripe webhooks keep your app's access rules in sync with payments, including failed-payment retries.
Organizations, invitations, role-based access control and per-feature permissions. For enterprise plans, we add single sign-on and an audit log of who did what and when.
Self-serve sign-up and an onboarding checklist for your customers; a super-admin console for your team with account lookup, plan overrides, feature flags and logged support access. For heavier reporting needs, see custom dashboard development.
Queues, scheduled jobs, email sequences and configurable business workflows. On .NET projects we use Elsa Workflows so workflows can be defined and adjusted without rewriting core code.
Live updates, notifications and presence indicators with SignalR, so users see changes from teammates without refreshing.
A documented REST API with API keys and webhooks, so customers can connect your product to their own stack, plus connectors to Zapier or Make if your customers live there.
CRMs built around your sales process rather than a generic pipeline: custom deal stages, quoting, commission rules, email and calendar sync, and the reports your managers really use. We also build ERP-style modules for orders, inventory and invoicing.
| SaaS MVP | Full platform | |
|---|---|---|
| Starts from | $10,000 | $30,000 |
| Goal | Prove that customers will pay | Serve and grow a paying customer base |
| Scope | One core workflow, sign-up, Stripe subscriptions, basic roles, essential admin tools | Multiple plans and usage billing, team management, SSO, public API, analytics, full admin console |
| Right for | New products, first paying customers, investor demos | Products with traction, or businesses productizing a proven internal tool |
If you haven't yet spoken to potential customers, consider validating on a no-code platform first. A Bubble MVP can test demand for less, and we can rebuild it in code once it works.
An MVP that tries to do everything ships late and proves nothing. We push for one sharp workflow first, and every feature in the proposal is tagged MVP, next release or later.
Tenancy model, billing model and permission structure are agreed in writing before development starts. Those three decisions are the hardest to change once real customers are on the platform.
Our SaaS stack covers .NET / C# on the backend with React or Next.js on the front end, or Node.js end to end, with PostgreSQL and Redis underneath. We choose based on your product and the team you plan to hire.
We sign NDAs on request before you share your idea. The code, designs and infrastructure accounts belong to you once the project is paid in full, with accounts created in your name from the start.
2,000+ projects across 15+ countries, with email replies in 2–4 business hours and a demo at the end of every development cycle.
A free call, then a scoping workshop: who the customer is, the job they need done, your pricing model and the competitors they'd compare you with.
Features split into MVP, next release and later, with a fixed price for the MVP and a written architecture outline covering tenancy, billing and roles.
A clickable prototype of sign-up, onboarding and the core workflow. Put it in front of prospective customers before writing code.
Short development cycles with a demo on staging after each. Containerized with Docker and deployed through an automated pipeline from the first sprint.
Onboard your first customers, monitor errors and usage, and collect feedback. Pricing and onboarding often change here, and the architecture allows for it.
A monthly retainer for new features, performance work and support as your customer count grows.
The closest SaaS-style build in our published work is The House Kee, a vacation-rental platform across Maryland, Delaware and Florida. Property owners register, choose a monthly or annual listing plan and sign in to manage their listing on the Commissioning Week marketplace, where guests reserve with a deposit through Stripe.
Read The House Kee case studySaaS development with us starts from $10,000 for an MVP and $30,000 for a full platform. Where your product lands depends on scope more than anything else.
Budget for ongoing costs too: cloud hosting that grows with usage, Stripe's processing and billing fees, email delivery and any paid APIs. We estimate these in the proposal.
You can work with us on a fixed price for the MVP, then a monthly retainer for continuous development, or hourly at $45/hour (minimum 40-hour block). Send your idea and you'll have an exact estimate within 48 hours.
A SaaS MVP with Wix Engine starts from $10,000, and a full platform from $30,000. The main cost drivers are the number of core workflows, your billing model, tenancy and security requirements, and integrations. Hosting and Stripe fees are separate running costs. We send a fixed-price MVP proposal after a free call and scoping session.
Most SaaS MVPs take 8–16 weeks from kickoff to beta launch. A tight scope is the fastest way to shorten that: one core workflow, one pricing model and essential admin tools. Full platforms are built in phases over several months, with a working release at the end of each phase.
Multi-tenant architecture means one application serves many customer organizations while keeping each one's data separate. Common approaches are a shared database with tenant IDs and row-level security, a separate schema per tenant, or a separate database per tenant. Shared databases cost less to run; separate databases give stronger isolation for enterprise customers.
Use no-code, such as Bubble, if you're still validating demand and need to launch quickly on a small budget. Choose custom code when you have paying customers or investors, need complex permissions or integrations, expect high usage, or need full ownership of the codebase. Many products start no-code and move to code after traction.
Yes. Once the project is paid, the source code, designs and documentation are yours, and the repository and cloud accounts are set up in your name. We sign NDAs on request before you share your idea, so it stays protected from the first conversation.
Yes, and sometimes that's the right move: when per-seat licences get expensive, or your sales process doesn't fit a standard pipeline. If an off-the-shelf CRM fits 90% of your needs, customizing it is usually cheaper. We'll compare both options honestly on the first call.
Our SaaS work typically uses .NET / C# or Node.js on the backend, React or Next.js on the front end, PostgreSQL and Redis for data, and Stripe for billing. We add SignalR for real-time features and Elsa Workflows for configurable business processes, with everything containerized in Docker.
Yes. After launch, a monthly retainer covers new features, performance work, security updates and support as your customer base grows. If you're building an in-house team instead, we hand over the codebase with documentation and can help onboard your first developers so nothing is lost in the transition.
Book a free 30-minute call, under NDA if you prefer. We'll pressure-test the idea, outline the MVP and send a detailed proposal within 24 hours.
