Custom software development for businesses

Custom Software Development

Custom software development for businesses

Software built precisely for your business: applications, platforms and management systems tailored to your processes. No templates. In-house team, fixed-price quotes and ongoing support.

Our approach

Software that solves real problems

Off-the-shelf solutions force your company to adapt to the software. We do the opposite: we deeply understand your business and build exactly what you need to grow without friction.

Our methodology

A proven process for delivery without surprises

01

Discovery and analysis

Before writing a single line of code, we invest time understanding your business, your users and your processes. We define scope, functional requirements and the technical roadmap.

02

Architecture and design

We design the solution architecture, user flows and interactive prototypes. We align the technical vision with business objectives before development begins.

03

Iterative development

We develop in 2-week sprints with continuous functional deliveries. Each iteration delivers real value and allows adjustments based on your feedback before the next phase.

04

QA and testing

Thorough testing at every sprint: unit tests, integration, performance and user testing. The software we deliver has been validated under real conditions.

05

Deployment and continuous support

We deploy with CI/CD for a frictionless launch. After go-live, we offer evolutionary maintenance, monitoring and support so the system grows with your company.

Guide for businesses

How to approach a custom software development project: what you should know before you start

This guide summarises what we explain in the first meetings with every client: what custom software development really is, when it pays off compared with an off-the-shelf product, which problems it solves in each sector, how it integrates with what you already use and which guarantees you should demand from a software development company. If your company is considering commissioning its own application, these are the criteria we use ourselves.

What custom software development is (and what it is not)

Custom software development means designing and programming an application specifically for one company, starting from its real processes rather than from a generic product. The result is a tool that does exactly what your business needs: managing orders with your pricing rules, planning production with your shifts, controlling the warehouse with your locations or serving your customers with your workflow.

It is not the same as customising a standard product. When an ERP is configured or modules are added to a platform, the product sets the limit; when software is built to order, your process sets the limit. Nor does it mean a long and expensive project: today a custom management application is built in phases, with a first operational version in weeks, and is extended according to priorities.

Custom software or standard software: how to decide

The decision is not ideological but economic and operational. These are the differences we usually put on the table when a company asks us whether custom software development or a market product is the right choice:

Criterion Custom software Standard software
Fit with your processes Total: designed around how the company works. Partial: the company adapts its processes to the product.
Initial cost Higher, proportional to the defined scope. Lower, in the form of licences or fees.
Long-term cost No per-user licences; agreed maintenance. Recurring licences that grow with users and modules.
Integrations Native, designed for your ERP, your website and your suppliers. Limited to the connectors the vendor offers.
Vendor dependency Low: the code and the data belong to the company. High: if the product changes or disappears, it drags the company along.
Competitive advantage Yes: nobody else has your tool. No: your competitors use the same product.

In practice, custom software pays off when the way you work is a differentiator, when the standard product needs so many adaptations that it ends up costing more, or when you want to unify in a single application what today lives in spreadsheets, emails and several programs that do not talk to each other. When the process is common to the whole sector and brings no advantage, a solid standard product such as our Gestinity ERP is usually the more sensible option, and we will tell you so.

Custom software by sector: what we solve in each industry

The custom software development projects that deliver the most value are those that tackle the process that sets the company apart. These are the most common cases by sector:

  • Industrial sector: production planning with shifts and machines, quality control with batch traceability, shop-floor work orders from tablets and integration with the ERP and maintenance.
  • Logistics and distribution: warehouse management with locations and picking, order preparation, carrier integration and order portals for customers and distributors.
  • Retail and commerce: catalogues with customer-specific price lists, omnichannel stock management between shops and website, loyalty programmes and sales dashboards per point of sale.
  • Transport: route and driver planning, trip and delivery reports with mobile signature, fleet control and automatic invoicing per service.
  • Service companies: project and time management, customer portals with documents and invoices, quote automation and internal approval workflows.

Integrations: custom software coexists with what you already use

A custom application does not replace everything you have. It usually relies on the ERP, the accounting system or the online store that already work, and adds the missing layer. That is why integration is part of the analysis from day one. The most frequent connections in our projects are:

  • ERP and management: Gestinity and the main ERP systems on the market, so customers, products, orders and stock are entered only once.
  • Accounting and e-invoicing: automatic sending of invoices and collections, compliance with Spain's Verifactu and SII systems.
  • Online stores and marketplaces: catalogue, price, stock and order sync with PrestaShop, custom stores and sales platforms.
  • Payment gateways, digital signature, email and calendar: to close the full cycle without leaving the application.
  • Artificial intelligence: document classification, demand forecasting and assistants trained on the company's own information.

Security, regulation and code ownership

Custom software handles the company's most valuable data, so security is not a final add-on. We work with role-based access control, encryption of sensitive data, activity logging, automatic backups and deployment on European infrastructure, and we align the measures with GDPR and, where applicable, the NIS2 directive.

Ownership matters just as much: the source code, the documentation and the database belong to the client company. You can host the application on your own infrastructure or on ours, and freely decide whether to continue with our evolutionary maintenance. A serious software development company should never tie you to it in order to use your own tool.

Signs that your company needs custom software

  • Your team maintains critical spreadsheets that only one person understands.
  • You enter the same data into two or three different programs every day.
  • Your ERP needs so many adaptations that every update is a problem.
  • You have ruled out several products because none fits your sales or production process.
  • You want to offer your customers or distributors their own portal and none of the existing ones fits.
  • You have a process that sets you apart from competitors and you do not want to depend on a vendor to improve it.

If you recognise yourself in two or more of these situations, an analysis meeting is worth it. We will tell you clearly whether your case calls for custom development, a standard product or a combination of both.

Why Grupo Unifema as your custom software development company

We are a software consultancy with our own analysis, development and support team in Spain, with offices in Murcia and Madrid and clients across the country. We build management applications, mobile apps, portals, SaaS platforms and integrations for SMEs and mid-sized companies in the industrial, logistics, retail, transport and services sectors, and we are also the makers of our own ERP, Gestinity, which gives us a complete view of how a company's management works.

We work with a closed scope and a written quote before starting, reviewable deliveries every two weeks, a warranty on what we deliver and optional maintenance. That method, not promises, is what allows us to say that the software we deliver gets used.

Pricing and timelines

What custom software costs and how long it takes

No two projects are alike, so there is no price list. What there is, is a method so you know the price before you start: we define the scope with you, put it in writing and send you a fixed-price quote within 48 hours. No unagreed extras once the project is under way.

We work across Spain from our offices in Madrid and Murcia, with on-site meetings during analysis and kick-off and continuous remote follow-up.

Request a no-obligation quote

What drives the price

  • Functional scope: how many processes it covers and how many user roles are involved.
  • Integrations with what you already use: ERP, accounting, payment gateways, external services.
  • Devices: web, desktop, mobile app, or all three.
  • Migration of historical data and the security or regulatory requirements of your sector.

Typical timelines

  • We deliver in phases: a first working version in weeks, not months, and from there it grows by priority.
  • From analysis to go-live there are reviewable deliveries every two weeks, so you see real progress.
  • The code is yours. You can continue with our evolutionary maintenance or not: you do not depend on us to use it.

Frequently asked questions

What clients ask before commissioning custom software

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

Off-the-shelf software forces you to adapt your processes to the product; custom software is built around how your company works. It pays off when your processes are a differentiator, when the standard product needs so many adaptations that it ends up costing more, or when you want everything in a single tool.

How much does custom software development cost?

It depends on scope, integrations and devices. That is why we do not publish rates: we define the scope with you and send a fixed-price quote within 48 hours, which is the final price unless you decide to extend it.

How long does it take?

We work in phases with deliveries every two weeks. The first working version is usually ready in weeks; the full project depends on the number of modules and integrations, and the schedule is set together with the quote.

Who owns the code and the data?

You do. We hand over the source code and documentation, and the software can be hosted on your infrastructure or the cloud of your choice. Ongoing maintenance is optional.

Does it integrate with our ERP, accounting or website?

Yes. Integration with the systems you already use (ERP, CRM, accounting, online store, payment gateways or external services) is part of the initial analysis and is built through APIs so data is entered only once.

Do you also build mobile apps and SaaS platforms?

Yes. We build web applications, iOS and Android apps, intranets, customer portals and multi-tenant SaaS platforms, with the architecture each case requires.

Do you work with companies outside Madrid and Murcia?

Yes, with companies all over Spain. We combine on-site meetings when the project requires them with continuous remote follow-up, and our technical team is in-house and based in Spain.
