Custom software

Custom software development

We build software around the way your company works: management dashboards, automations, integrations between tools and internal platforms. We work with companies that outgrew their spreadsheets and are losing time and money to manual processes.

Every growing business hits the point where off-the-shelf software no longer fits. Teams build side spreadsheets, copy data between tools and depend on the one person who knows where everything is. That rework costs hours every week and invites mistakes.

Custom software fixes the problem at the root: it follows your process instead of forcing you to follow it. We map how operations run today, where the bottlenecks are and which tasks can be automated. Then we build only what makes a difference, in milestones that deliver value from the first release.

As a full-service software house, we handle the whole project: architecture, database, interfaces, integrations, security and hosting. You get a reliable system without having to hire and manage an in-house engineering team.

Who it is for

  • Companies running operations, sales or finance on spreadsheets that no longer keep up.
  • Businesses using several tools that don’t talk to each other.
  • Operations with repetitive tasks that could be automated.
  • Teams that need real-time dashboards to make faster decisions.
  • Companies stuck with legacy software that is hard to maintain.

What we deliver

Business management systems

CRM, order management, inventory, finance, targets and reporting built around your operation.

Dashboards

Your key business metrics in one place, updated automatically.

Automations

Repetitive tasks handled by the system: billing, reminders, reports and lead intake.

Integrations

Connections between ERP, CRM, payment providers, spreadsheets, messaging and third-party APIs.

Access control

Roles and permissions so each person sees and edits only what they need, with an audit trail.

Data migration

We move data from spreadsheets or legacy systems into the new platform safely.

Examples of custom systems

Systems that remove common bottlenecks in growing companies:

Sales CRM

A pipeline that matches how your team sells, with tasks, contact history and targets per rep.

Order and production management

From order to delivery, with status per stage, owners and delay alerts.

Finance and billing

Receivables, automatic billing, reconciliation and cash flow reports.

Partner portal

A space for partners and resellers to check prices, place orders and track commissions.

KPI dashboards

Sales, operations and finance in one dashboard, fed by the systems you already use.

Tool-to-tool automation

Data that flows on its own between CRM, spreadsheets, email and messaging, with no copy and paste.

How we build your system

  1. Process mapping

    We follow how the work happens today and list bottlenecks, rules and integrations.

  2. Architecture

    We define modules, database, permissions and integrations, and prioritize what ships first.

  3. Prototype

    The team that will use the system validates the main screens before development.

  4. Iterative delivery

    We ship working modules in short cycles so your team starts using them early.

  5. Rollout

    We migrate data, train the team and move the system into production.

  6. Support and evolution

    We monitor usage, fix what is needed and keep improving the system as the company grows.

Technology

A modern, well-documented stack that any future team can maintain.

  • TypeScript
  • Node.js
  • Python
  • React
  • Next.js
  • PostgreSQL
  • Supabase
  • MongoDB
  • Docker
  • AWS
  • REST APIs and webhooks

Timeline

The timeline depends on the number of modules, the integrations and the quality of your current data. Instead of one long project with a single delivery at the end, we split the system into milestones, and each one ships something the team uses every day.

Each milestone is scheduled in the proposal. The first module goes after the bottleneck that costs your company the most.

How much does custom software cost?

Pricing is based on scope, with a fixed quote per milestone before we start. The main drivers are:

  • Number of modules and business rules.
  • Integrations with existing systems and the quality of their APIs.
  • Data migration from spreadsheets or legacy systems.
  • Number of user roles and permission or audit requirements.
  • Hosting, support and ongoing development after rollout.

A useful benchmark is the number of hours your team spends on rework today, plus the cost of manual errors.

Custom software FAQ

What is the difference between custom and off-the-shelf software?

Off-the-shelf software makes your company adapt to it. Custom software is built around your process, with the rules, screens and integrations your operation needs. It makes sense when packaged tools no longer fit or when the process itself is a competitive advantage.

How much does custom software cost?

It depends on modules, integrations and data migration. You receive a fixed quote in the proposal, split by milestone, before we start.

Can you integrate with the tools we already use?

In most cases, yes. We integrate via API, webhooks or data imports with ERPs, CRMs, payment providers, spreadsheets and messaging tools, and we assess every integration during discovery.

Is our data secure?

Systems are built with role-based access control, protected databases and secure development practices. We decide together where the system will be hosted.

Can we start small?

Yes. We start with the module that removes the biggest bottleneck and grow in milestones. Your team uses each part as soon as it is ready.

Do you provide support after delivery?

Yes. We offer support, fixes and ongoing development under maintenance plans.
