Clean architecture
Typed, documented code ready to scale. We don't inherit technical debt, we avoid it.
Services
Custom software
Standard software solves standard problems. But if your business has unique processes, you need unique tools. At Suto Studio we design and build custom software that fits exactly how your team works, not the other way around.
From complex web applications to mobile and desktop clients, every project is tackled with product vision, clean architecture and a long-term relationship.
Signs this is for you
If any of these sounds familiar, we can probably help.
We've asked for quotes and we're told it can't be done with standard software.
Our business works in a very particular way and we can't find a tool that fits.
We have a tool that's falling short and we need to move to something custom.
We want our own product without depending on a template or a limited SaaS.
We have an MVP built by others that needs stabilizing and evolving.
Licence and configuration costs already exceed what a custom build would cost.
Product thinking
We understand what truly solves your problem before writing any code.
Modern stack
TypeScript, PostgreSQL, containers, CI/CD and observability from the first commit.
Performance
We measure and optimize load times, queries and UX continuously.
How we work with you
Three clear phases from the first call until the system is running in your operation.
Phase 01
Understanding your operation
We talk to your team and map real workflows, bottlenecks and priorities. We leave with a clear picture of what to solve first.
Phase 02
Technical design
Architecture, integrations with your current systems, risks and a phased plan. Before writing any serious code, we agree on the how.
Phase 03
Go-live and support
Controlled rollout, team training, monitoring and early adjustments. We stay with you during the first weeks until everything runs on its own.
What we build
- - Internal web platform for multi-warehouse logistics
- - Mobile app for industrial machinery management
- - B2B marketplace with real-time pricing and availability
- - Control panel for industrial operations with connected hardware
What you take home
Concrete outcomes at the end of the engagement. Not slides — things that run.
- A tool built around how your team actually works, not the other way around.
- Fewer human errors and fewer tasks that depend on someone remembering to do them.
- Processes that used to live in people's heads and spreadsheets, now centralized in the system.
- Business information available whenever you need it, without cross-checking files or asking anyone.
- Full autonomy: the software is yours and you can evolve it with whoever you want.
- An internal team trained and comfortable with the tool from day one.
What shapes a custom software project
Functional scope
Number of modules, roles, approval flows and operational exceptions the system must cover on day one versus later phases.
Integrations
ERPs, WMS, machinery, IoT sensors, third-party APIs or legacy files to connect without disrupting daily operations.
Users and deployment
How many people will use it, from which devices (web, mobile, shop floor) and whether high availability or isolated environments are required.
Operational criticality
If the software controls production, food traceability or real-time logistics, architecture and testing require more rigour.
Timeline and phases
Whether you need an MVP in weeks or a full platform over several quarters changes planning and team allocation.
Internal team
If you have in-house IT we can work hybrid; if not, we take more responsibility for deployment and training.
Every project is different. In a discovery call we analyse your case and propose a realistic scope, with no obligation.

| Generic SaaS | Standard ERP | Custom software | |
|---|---|---|---|
| Fit to your processes | Limited configuration | Wide parameterisation | Designed from scratch for your operations |
| Initial time-to-value | Fast for standard cases | Long (implementation + setup) | Medium: MVP in weeks, phased evolution |
| Flexibility to change | Low: vendor roadmap dependency | Medium: costly upgrades and customisations | High: evolve the product with your business |
| Code ownership | No | No (licence) | Yes, from the first commit |
| Industrial integrations | Generic connectors | Standard modules | Tailored: OPC-UA, MQTT, custom APIs |
| Long-term maintenance | Subscription + discontinuation risk | Licence + upgrade consulting | Retainer with a team that knows the system |
Illustrative scenarios
Manufacturing shop with Excel-based planning
- Context
- A manufacturing company manages production orders, materials and times in shared spreadsheets.
- Challenge
- Version errors, no traceability and no real-time visibility of each order status on the shop floor.
- Approach
- Internal web panel connected to the existing ERP: visual planning, operator time logging and deviation alerts.
- Outcome
- Fewer planning errors, full batch traceability and management visibility without manual reports.
Multi-warehouse logistics operator
- Context
- A logistics operator coordinates several warehouses with different picking rules, cross-docking and carriers per client.
- Challenge
- The standard WMS does not cover commercial exceptions or the operator's own allocation logic.
- Approach
- Custom orchestration layer on top of the WMS: business rules, client portals and bidirectional sync.
- Outcome
- Unified operations without replacing the base WMS, fewer incidents from misapplied rules and clients with their own visibility.
Food company with strict traceability
- Context
- A food company must guarantee batch traceability, expiry dates and sanitary records at every stage.
- Challenge
- Paper processes and disconnected systems that make audits and incident response difficult.
- Approach
- Traceability system integrated with production and warehouse: scanning, batch genealogy and audit reports.
- Outcome
- Faster audits, batch-to-batch traceability in seconds and less recall risk from missing data.
B2B distributor with complex commercial rules
- Context
- A B2B distributor works with client-specific price lists, volume discounts and stock across several warehouses.
- Challenge
- The web catalogue and ERP do not share the same commercial logic; sales reps redo quotes manually.
- Approach
- Custom B2B portal with real-time pricing engine, consolidated stock and orders straight to the ERP.
- Outcome
- Sales reps freed from repetitive tasks, clients with reliable self-service and fewer order errors.
FAQ
How long until the first feature is in production?
In typical projects, between 6 and 10 weeks. We deliver in short phases so you start using the system while we keep building the rest.
Who owns the code?
You do. Every line is yours from the first commit, with no dependencies or lock-in. We hand over the repository, documentation and access to all infrastructure.
How do you work with our internal team?
We adapt to how you already work. We can lead development, support your technical team on specific parts or pair-program to transfer knowledge during the project.
What happens if requirements change mid-project?
That is expected. We work in short closed phases of a few weeks, so you can reprioritize between phases without renegotiating the whole project.
How do you scope a project without commitment on day one?
In a short discovery call we understand your operations, priorities and constraints. If it fits, we propose a phased scope with concrete deliverables. No pressure: if we are not the right partner, we will say so.
What technologies do you use?
TypeScript, React, Astro, Node.js and PostgreSQL as our usual base. We choose stack based on integrations, performance and your internal team, not trends.
Do you offer maintenance after launch?
Yes. Many clients continue with an evolution retainer: improvements, new features and support from a team that already knows your operations.
Can you integrate with our existing ERP or machinery?
Common in industrial projects. We connect ERPs, WMS, sensors, third-party APIs and legacy spreadsheets to eliminate manual re-entry.
How do you handle data migration from Excel or other systems?
We map sources, validate quality and migrate in phases with controls. We never cut over until the new system is validated in production.
Can the project qualify for R&D tax incentives?
In some cases, if the software delivers substantial technological novelty. It is not automatic: worth reviewing with a tax advisor. We help document the technical scope.
Do you work only in Spain?
We are based in Sabadell (Barcelona) and work with companies in Spain, Italy and the UK. The team is remote-first with meetings in Spanish, Catalan, English or Italian.
What do you need from us to get started?
A reference person in operations or IT, access to how you work today (even with spreadsheets and screenshots) and clarity on which problem to solve first. We handle the rest.
