Your custom SaaS software, delivered in record time

Off-the-shelf software forces your business to fit its boxes. Our custom SaaS development works the other way around: we design the application around your processes, with AI built in from the start. Thanks to AI-assisted development and proven building blocks, your software ships in record time.

The problem: generic tools that do not fit your business

Off-the-shelf software covers the average needs of an entire market. Your business is different: your processes and your billing rules never quite fit the boxes it provides.

So your team works around the tool: an extra spreadsheet, double entry. Every workaround costs time and creates errors.

What this costs your business:

  • Per-user subscription fees, even for unused features.
  • Data scattered across tools that do not talk to each other.
  • Feature requests that never ship.
  • Dependence on software you do not control.

The software businesses need the most

We build custom SaaS software to answer specific business needs. Here are the applications companies ask us for most often.

  • Custom CRM: track prospects and customers with the fields and stages your own sales cycle needs.
  • Client portal or extranet: give your customers secure access to their documents and case status.
  • Ticketing and customer support: centralize customer requests and track them from start to resolution.
  • Scheduling and appointment booking: organize your team and resources with a calendar built for your business.
  • Quoting and invoicing: generate documents with your own templates and pricing rules.
  • Inventory and order management: track stock levels and movements in real time.
  • Intranet and document library: share internal procedures and documents in one organized space.
  • Dashboards: view your key metrics in one place, with no manual exports.
  • Business back-office: manage your data and users with permissions suited to each role.

Why it is fast: AI-assisted development and proven building blocks

Delivering custom software in record time is not a shortcut on quality. It is a way of working.

Our developers use AI-assisted development: part of the code and the tests is generated by AI, then reviewed and approved by a developer. AI speeds up the writing, but a developer stays accountable for what ships to production.

We also start from proven building blocks instead of rebuilding everything from scratch: authentication and roles, exports, APIs, and our React and Supabase client portal, already running in production at MarketerZ.

Finally, we work in short iterations: a usable first version early on, followed by incremental additions.

AI built in from the design phase

In our custom software, artificial intelligence is not bolted on afterward. It is part of the initial design, whenever it serves how you use the software.

Depending on your needs, your software can include search across your documents, an assistant that helps users, or automations that trigger actions on your behalf.

These automations rely on the same technology as our automation and orchestration service, using n8n. For more advanced needs, your software can also include an enterprise AI agent that traces every decision.

Your data stays yours, and so does your hosting

Custom software should never lock you in. We build every project on this principle.

What this means in practice:

  • Your data belongs to you and stays exportable at any time.
  • You choose the hosting: in the cloud or on your own servers.
  • No per-user license fees.
  • Code ownership terms are spelled out in your quote, with a clear usage right from day one.

This transparency lets you evolve your software or switch hosting providers if you choose to.

Our method: from scoping to production

We follow the same four-step method regardless of project size.

  1. Free consultation and needs audit: we listen to your current processes and where they break down.
  2. Custom design and prototype: a mockup, then a usable first version (MVP).
  3. Short iterations and integration: features get added in stages, connected to your existing tools, with testing at every step.
  4. Production launch, monitoring, and maintenance: your software goes live, then gets ongoing monitoring and monthly maintenance.

This method limits bad surprises. You see your software take shape early, and can redirect the project in time.

Under the hood

We choose the technical stack based on your needs. On the server side, PHP or Python with FastAPI. On the interface side, React. Data is stored in PostgreSQL or Supabase.

Every project is containerized with Docker, which makes deployment and switching hosting providers easier. Automations run through n8n. Our builds include automated tests, run on every code change.

This approach follows the same principles as our enterprise AI agents: an open, documented stack, with no proprietary black box.

Frequently asked questions

The timeline depends on how complex your project is. We speed up delivery through AI-assisted development under developer control and proven building blocks. We give you a precise schedule after the scoping workshop.

Our terms and conditions of sale grant you a usage right to your software, without a transfer of code ownership by default. A full ownership transfer is possible and gets defined in your quote, based on your needs.

Yes. We offer monthly maintenance and updates based on your needs. Your data stays exportable at any time, with us or with another team.

Custom SaaS software is a full application, with its own interface and database. It can include n8n automations or an enterprise AI agent, whenever your needs call for it.

You choose: hosting in the cloud or on your own servers, based on your security and GDPR compliance requirements. We discuss this choice during the scoping workshop.
