## In short
SaaS development is building a subscription software product that many customers use from the cloud. LOLCorp designs and builds multi-tenant SaaS platforms with billing, roles, analytics and scalable infrastructure, from first MVP through growth. We also run our own SaaS products, such as GoFloe and PushCo.

## SaaS development services from idea to scale
As a SaaS development company, we provide end-to-end SaaS development services: SaaS product development from the first prototype, SaaS application development with billing, roles and analytics, and the cloud infrastructure to scale it. If you are looking for a SaaS development company UK founders can work with closely, our London team builds multi-tenant platforms to a fixed scope and price.

We often start with an [MVP](https://lolcorp.co.uk/services/mvp-development/), then iterate with real customers. Our guide [how to build a SaaS product](https://lolcorp.co.uk/guides/how-to-build-a-saas-product/) covers the full journey.

## Why teams choose LOLCorp for SaaS Development

- **Billing that works:** Subscriptions, usage metering, invoices and dunning through Stripe or your provider of choice.
- **MVP to scale:** Start lean, then grow on infrastructure that scales horizontally without a rewrite.
- **Investor-ready:** Clean architecture, documentation and metrics dashboards that stand up to due diligence.

## Deliverables
- Product strategy and MVP scoping workshop
- Multi-tenant architecture and data model
- Subscription billing and customer self-service

## How it works
1. **Validate:** Define the smallest release that proves demand and earns its first paying customers.
2. **Architect:** Pick a stack and data model that scales commercially as well as technically.
3. **Build:** Ship the MVP in focused sprints with analytics wired in from the first release.
4. **Grow:** Iterate on real usage data with a retainer or hand to your in-house team.

## FAQ
### How much does it cost to build a SaaS product?
It depends on scope: features, tenants, billing complexity and scale. A focused MVP costs far less than a full platform. The instant quote tool gives you an indicative range in under a minute.

### Can you take over an existing SaaS codebase?
Yes. We start with a code and infrastructure audit, then stabilise, document and extend it.

### Which technologies do you use?
Typically TypeScript, React, Node, Python and PostgreSQL on AWS, GCP or Azure, chosen to fit your team and roadmap.
