Software development for a business that runs with the business – and lasts for years.
Software development (SD) means creating software tailored to your business needs – from design and development to deployment and maintenance. When an off-the-shelf solution does not cover all business processes or multiple systems need to be linked, custom development usually makes more sense than adapting an off-the-shelf solution.
Web Systems has been developing software for over 20 years. We have developed business software, information systems and interfaces for the private sector as well as public institutions – including Tartu University Hospital, Tallinn Education Authority, Viljandi Hospital SA and Estonian Language Institute. For us, software development for a company is not a one-off transaction, but a long-term partnership where the partner stays after the implementation.

What is software development
Software development is the process of creating software – planning, designing, programming, testing and maintaining software. In practice, it means creating a system tailored to the needs of a specific business: be it business software, a mobile application, an information system or an interface between multiple platforms.
The difference compared to an off-the-shelf solution is clear. In the case of off-the-shelf software, the business processes have to match the software logic. With custom development, it’s the other way round – the software follows the actual workflows of the company. This provides better integration, automation and room for growth.
What software solutions we create
We provide software development for businesses – both small and medium sized enterprises that need customized information systems or business applications. Below are the four main types of solutions we deal with.
Business software and information systems
Internal systems that support work processes — order management, client portals, internal workflow applications, MVP prototypes. Suitable for a company that needs specific functionality that off-the-shelf software does not provide.
Mobile applications
iOS and Android applications that offer customers a better user experience or create new digital services. We develop both native (Swift, Kotlin) and cross-platform (Flutter, React Native) solutions.
Business software integrations
We connect e-shops, websites and CRM systems with business software — Directo, Erply, Merit Aktiva, NOOM, Eeva, Excellent, SAF. Data exchange is automatic, no manual entry required.
Portal and API integrations
One- and two-way integrations between systems. Forwarding orders from an e-shop to accounting software, sending customer data to CRM, integrating with logistics service providers — all securely and smoothly.
Technologies used
We always choose the technology according to the needs of the project – not the other way around. Below are the main technologies and platforms we work with, from which we choose the most appropriate combination for each project.
Front-end development
React, Vue, Angular, Next.js, Nuxt.js, TypeScript. Modern JavaScript frameworks for reactive user interfaces.
Back-end development
Laravel (PHP), Node.js, .NET, Python. Building a strong API layer, database logic and business logic layer management.
Mobile applications
Swift (iOS), Kotlin (Android), Flutter and React Native for cross-platform solutions. We choose the stack based on user experience and maintenance costs.
Databases and servers
MySQL, PostgreSQL, MS SQL, MariaDB, SQLite. LiteSpeed, Apache and Nginx servers — depending on the scale and performance requirements of the project.
Cloud and DevOps
AWS, Azure, Hetzner, Docker, CI/CD pipelines. Scalable infrastructure and automated deployment.
AI and automation
OpenAI API, Claude API, custom ML models, RPA solutions. AI-integrated business process automation is a growing part of our projects.
Agile software development process
The software development phases at Web Systems are based on an agile methodology – iterative development in short sprints, regular feedback from customers and the ability to change course before costs become too high. Below are the six key steps through which every project moves.
1. Preliminary work and analysis
We map the company’s needs, existing systems and goals. Based on this, we create a development plan — what to build, in what order and with what technologies.
2. Design and prototyping
We create user interface prototypes in Figma. The client sees the system logic and UX before a single line of code is written. We adjust the design based on feedback until it precisely meets the requirements.
3. Sprint development
Development takes place in 2-week sprints. At the end of each sprint there is a demo where the client sees the completed functionality and can give feedback. This reduces the risk of major rework at the end.
4. Testing
Automated unit tests, integration tests and manual quality control. Testing is not a separate stage — it runs in parallel with development.
5. Deployment
Installing the system in the production environment, user training and handover of documentation. Deployment is done gradually to avoid disruption to business operations.
6. Maintenance and further development
After deployment, the collaboration continues — security updates, bug fixes, additional development. Web Systems remains a long-term partner, not a one-off supplier.
What clients say about our work
Web Systems on partner, kelle peale saab kindel olla. Töö on täpne, kommunikatsioon selge ja kvaliteet ühtlane — Nahakliiniku digitaalne pool on hoolega hoitud. Selline järjepidevus on meie jaoks olnud koostöö suurim väärtus.
Meie koostöö Web Systemsiga kestab juba peaaegu 20 aastat ning selle aja jooksul oleme nende meeskonnale usaldanud nii veebiarendused, sisemised süsteemid kui ka reklaammaterjalid. Kahe aastakümne jooksul on tehnoloogia korduvalt muutunud, meie vajadused kasvanud ja turg arenenud – Web Systems on alati kaasas käinud ning pakkunud lahendusi, mis vastavad ajale. Selline pikk partnerlus ei sünni juhuslikult: see põhineb usaldusel, järjepideval kvaliteedil ja arusaamisel, et tehtud töö peab päriselt toimima. Web Systems ei ole meie jaoks teenusepakkuja, vaid meie meeskonna loomulik osa.
Pöördusime Web Systemsi poole ambitsioonika ideega – luua Eesti esimene kinnisvara e-pood. Meeskond ei piirdunud pelgalt tehnilise teostusega, vaid tuli kaasa mõtlema, kuidas teha lahendus kliendile võimalikult sujuvaks. Tulemus rääkis ise enda eest: esimesed korterid broneeriti otse veebist ära – midagi, mida Eesti kinnisvaraturul polnud varem nähtud. Soovitame Web Systemsi kõigile, kes otsivad partnerit, kellel jätkub nii tehnilist oskust kui ka julgust uusi ideid ellu viia.
Meie äri – autode müük ja täisteenusrent kolmel Baltikumi turul – nõuab IT-partnerit, kes on kättesaadav iga päev, mitte ainult siis, kui tahame uut lehte teha. Web Systems on meie kõrval just sellisena: nad on ehitanud mobire.ee ja morecar.ee platvormid, hoolitsevad nende igapäevase toimimise eest ning arendavad süsteeme koos meie ärikasvuga. Meeskond tunneb meie äri, mõistab erinevate turgude nüansse ja suudab reageerida kiiresti ka keerulistes olukordades. Meie jaoks on Web Systems osa meie igapäevasest töövoost – mitte väline teenusepakkuja, vaid sisuline partner.
Oleme kasutanud Web Systems OÜ veebiarenduse teenuseid ning jäänud koostööga väga rahule. Projekti käigus oli suhtlus selge, kiire ja professionaalne ning kokkulepitud tähtaegadest peeti kinni.
Arendaja suutis hästi mõista meie vajadusi ning pakkus välja ka omapoolseid lahendusi, mis aitasid lõpptulemust oluliselt parandada. Valminud veebileht ja e-pood on funktsionaalne, kasutajasõbralik ja visuaalselt kaasaegne.
Eriti hindame tehnilist pädevust, paindlikkust ning valmisolekut leida lahendusi ka keerukamatele ülesannetele. Samuti toimib järelteenindus sujuvalt – kõik täiendused ja parandused saavad kiiresti tehtud.
Soovitame Web Systems OÜ teenuseid kõigile, kes otsivad usaldusväärset ja kompetentset veebiarendajat.
Oleme teinud Web Systemsiga koostööd mitme kinnisvaraprojekti veebilahenduse loomisel ning iga kord on tulemus olnud nii kvaliteetne, et tagasi tulemise üle ei ole pidanud kahtlema. Meeskond mõistab kinnisvarasektori eripära – et iga projekt vajab oma nägu, kiiret turuletulekut ja lahendust, mis päriselt müüb. Tähtajad on alati peetud, suhtlus selge ja probleemid lahendatud enne, kui me neid ise oleme märganud. Web Systems on meile muutunud kinnisvaraprojektide veebilahenduste osas loomulikuks esimeseks valikuks.
Tartu Ülikooli Kliinikum on veebilahenduste osas teinud koostööd Web Systemsiga ning oleme olnud koostööga igati rahul. Meeskond saab aru, et suures meditsiiniasutuses on erinevad vajadused, erinevad osapooled ja nõuded, millega tuleb arvestada. Web Systems on pakkunud lahendusi, mis on olnud nii tehniliselt kvaliteetsed kui ka meie organisatsiooni eripäradele kohandatud. Eriti hindame seda, et meeskond kuulab, mõtleb kaasa ja arvestab alati meie soovidega.
Software development lifecycle
The software is not ready at the moment it goes into production for the first time. The software development lifecycle covers the entire life of a system – from conception to obsolescence or replacement. Each stage brings different needs and requires different skills.
- Concept and MVP – Validation of idea, prototype, rapid launch of first version to market.
- Active development – adding functionality, adapting based on user feedback
- Production level – stable use, performance work, security upgrades
- Maintenance and optimisation – long-term support, technical debt reduction, minor upgrades.
- Migration or replacement – replacing an old platform with a new one, migrating data.
Web Systems supports the customer at all stages. We offer both rapid development of the first version (MVPs in 2-3 months) and long-term maintenance and further development of systems already in production.
How we differ from other software development companies
There are several software development companies and software development firms in Estonia – large international consultancies, local agencies and individual developers. Each approach suits different customers. Below are three things that set Web Systems apart.
- Directly with the developer, not with a chain of project managers. In the case of larger consultancies, the client’s request reaches the developer through 3-5 intermediaries. With us, the client communicates directly with the people writing the code – faster decision making, less information loss.
- 20+ years of expertise in Estonia. We are familiar with the Estonian business software ecosystem (Directo, Erply, Merit, NOOM, SAF), national systems and data protection requirements. Multinational companies start every project by “learning the Estonian market around”.
- A long-term partner, not a one-off supplier. Many of our clients have worked with us for 5-10+ years. Software evolves with the business – we don’t disappear after the first version is deployed.

What is software development?
Software development is the process of creating software – planning, designing, programming, testing and maintaining it. In Estonian, the synonym software development is also used. In practice, it refers to the creation of a system tailored to a company’s needs, be it business software, a mobile application, an information system or an interface between multiple platforms.
What is the hourly rate for software development?
The hourly rate for Web Systems software development is 60 € + VAT. This includes developer, analyst and project manager work. Each project includes at least 100 hours of work. For larger projects, we will give a specific fixed price after mapping the needs.
What are the stages of software development?
The stages of software development are usually: 1) preliminary design and analysis, 2) design and prototyping, 3) sprint development, 4) testing, 5) deployment, 6) maintenance and further development. In the Agile methodology, development and testing run in parallel as 2-week sprints.
How long does a software development project take?
The duration of development depends on the complexity of the project. A simple MVP can be completed in 2-3 months. A medium-sized business software or information system will take 4-8 months. Larger solutions with multiple integrations can take 8-18 months. We will determine the exact timeframe after an initial consultation and needs mapping.
What is the software development lifecycle?
The software development lifecycle describes the software lifecycle from conception to obsolescence: concept and MVP, active development, production stage, maintenance and optimisation, and finally migration or replacement. Understanding the lifecycle helps to plan investments and avoid software becoming unsustainable over the years.
What’s the difference between agile and classic development?
Classic (waterfall) software development moves in stages – the whole system is designed, then developed, then tested. Agile development works in short sprints (2 weeks) with working functionality at the end of each sprint. The agile approach reduces the risk of major rework at the end. Web Systems uses a predominantly agile methodology.
Can we interface with existing systems?
Yes. Interfaces are one of our core activities. We connect your e-shop, website or CRM system to accounting software (Directo, Erply, Merit, NOOM, SAF), logistics service providers, payment solutions or other APIs. We can create both one-way and two-way interfaces as required.
Do you offer after-sales service?
Yes. We provide software maintenance, security updates, bug fixes and additional enhancements even after the project is completed. Long-term cooperation is our principle – many customers have been working with us for 5-10+ years. Maintenance is available on a monthly or hourly basis.
How is Web Systems different from other software development companies?
Three key differentiators: 1) the client interacts directly with the developer, not with a 5-level project management chain; 2) 20+ years of experience in the Estonian business software ecosystem (Directo, Erply, Merit, etc.) and national systems; 3) a long-term partner – we don’t disappear after the first version is deployed, we continue to develop and maintain.
