Custom Software
Custom Software Built Around Your Business
Off-the-shelf tools rarely fit how your business actually works. We design and build custom software — internal dashboards, workflow tools, CRM portals, and SaaS MVPs — that do exactly what you need and nothing more.

When custom software is the right decision
Custom software is justified when the gap between what existing tools provide and what your business needs causes real friction — manual workarounds, duplicate data entry, or staff using three separate systems to complete one task.
At Yarify, we build software in the €5k–20k range: focused tools that solve a specific problem cleanly, rather than bloated platforms that introduce new ones. Every project starts with a scope document that defines what gets built, what does not, and what happens afterward.
We work in the English-speaking European market. Timezone alignment, clear written communication, and EU data residency are defaults — not premiums.
What Every Custom Software Project Includes
Scope Document Before a Line of Code
Every project starts with a written scope: what the software does, what it does not do, how users access it, and what the acceptance criteria are. This is the single biggest factor in whether a project delivers on time.
Modern Technology Stack
Built with Next.js, TypeScript, and PostgreSQL or similar — readable, maintainable code that any competent developer can work with after we hand it over.
Secure Authentication & Access Control
Role-based access, secure session handling, and proper data isolation built in from the start — not added later when a security review flags the absence.
API-First Architecture
Clean REST or tRPC APIs so your software can connect to other tools — CRM, ERP, payment providers, external data sources — without custom middleware hacks.
Responsive UI for All Devices
Admin panels and internal tools used on mobile and tablet as well as desktop. Built responsive by default, not as an afterthought.
Deployment & Hosting
Deployed to Google Cloud Run or similar container infrastructure with SSL, environment separation (staging/production), and uptime monitoring from day one.
Documentation & Handover
You receive full source code, a README covering local setup and deployment, and a short walkthrough of the key architectural decisions. No lock-in.
Post-launch Support Window
Two weeks of included bug fixes after go-live. Beyond that, we offer maintenance plans or work on a time-and-materials basis — your choice.
Types of Custom Software We Build
Internal Tools & Dashboards
Custom admin panels, operations dashboards, and internal workflow tools built around how your team actually works — not around a vendor's generic feature set.
SaaS MVPs
First version of a product that real users can pay for. Scoped tightly, built fast, deployed properly — so you can validate before investing in a full platform.
CRM & Client Portals
Custom CRM systems built around your sales process, or client-facing portals where customers can track orders, documents, and communication in one place.
System Integrations
Middleware and integration layers that connect your existing tools — accounting software, e-commerce platforms, marketing systems — without manual data export and import.
Reporting & Analytics Platforms
Internal reporting tools that pull data from multiple sources and present it in a single view — replacing manual spreadsheet assembly with automated, real-time dashboards.
Business Process Automation
Software that handles repetitive, rule-based processes automatically — order routing, invoice generation, lead assignment, notification workflows — without human intervention.
Who This Service Is For
Operations Teams Running on Spreadsheets
If your team maintains business-critical data in Google Sheets or Excel — order tracking, project status, client records — a purpose-built internal tool eliminates the version control issues, access problems, and manual errors that grow with the spreadsheet.
Founders Who Have Validated an Idea
If you have paying users or strong evidence of demand and need a properly built first version — not a no-code prototype — we scope and deliver the core product without the overhead of a full agency engagement.
Businesses Using Three Tools to Do One Job
If your workflow involves exporting data from one system, manually reformatting it, and uploading it to another, a custom integration or lightweight internal tool eliminates the overhead permanently — and removes the error surface that comes with it.
Companies That Have Outgrown Their Current Software
If you started with an off-the-shelf solution that worked for your first 20 clients but no longer fits how you operate at 200, custom software built for your actual scale is often more cost-effective than adapting a generic platform with workarounds.
Why most custom software projects fail — and how we avoid it
The majority of custom software projects that overrun or fail to deliver do so for the same reasons: requirements were ambiguous at the start, scope expanded during development, and neither party had a shared definition of done.
The standard failure mode is a project that starts with a vague brief, generates a beautiful prototype, and then spends six months in revision cycles as the real requirements emerge. By the time the final version ships, the original timeline is three times over and the relationship between client and developer is strained.
Our model requires a written scope document before any development work begins. This document describes every screen, every data entity, every integration, and every user role the software will have at launch. It is not a design specification — it is a contract between us about what counts as done. Requests that fall outside this document become a new phase, not an extension of the current one.
This discipline is what allows us to quote a fixed price for projects in the €5k–20k range with confidence. The quote is accurate because the scope is defined. If the scope changes, the price changes proportionally — and both parties agree to that change explicitly before work continues.

How We Build Custom Software
Our process is built around scope certainty and short feedback loops. Ambiguity in requirements is the primary cause of software projects overrunning — so we eliminate it before writing the first line of code.
Discovery & Requirements
We start with a structured requirements session: what problem the software solves, who uses it, what data it manages, what integrations it needs, and what success looks like at launch. This is documented and signed off before development begins.
Technical Architecture
We define the data model, API structure, authentication approach, and deployment architecture. Decisions are documented so any developer can understand the system without asking us.
Iterative Development with Weekly Check-ins
We build in short cycles and share working software weekly — not just screenshots or Figma mockups. You can use the staging environment to verify behavior against requirements in real time.
Acceptance Testing Against Requirements
Before handover, we test every requirement in the scope document. Bugs discovered during this phase are fixed before go-live. Features outside the scope document are not added without a formal change request.
Deployment & Knowledge Transfer
We deploy to production, configure monitoring, and walk through the codebase with your team or future maintainers. Documentation is written for the developer who inherits the project, not just the end user.
Our Custom Software Development Process
Discovery & Scoping
We interview stakeholders, map existing workflows, and produce a written scope document with requirements, data model, and timeline. You approve this before we write any code.
Architecture & Design
We design the technical architecture and key UI flows. Internal tools get functional wireframes; client-facing products get full visual design in your brand.
Development
We build iteratively with weekly staging deployments. You can test against requirements throughout — no big reveals at the end.
Acceptance & QA
We test every scoped requirement, run security checks, and verify performance under realistic load before calling the project done.
Deployment & Handover
We deploy to production, configure monitoring and alerting, and hand over source code, documentation, and access credentials.
Support & Iteration
Two weeks of included bug fixes post-launch, then ongoing maintenance or feature development on a schedule that fits your roadmap.
Before and After
| Before | After |
|---|---|
| Team maintains critical business data in shared spreadsheets with no version control, access management, or audit trail. | Purpose-built internal tool with role-based access, audit log, and a single source of truth for every team member. |
| Three separate tools used to complete one workflow — data exported from one, reformatted manually, imported into another. | Custom integration layer that moves data between systems automatically, eliminating manual steps and the errors that come with them. |
| Off-the-shelf CRM or project management tool adapted with workarounds to fit a workflow it was not designed for. | Custom software that matches exactly how the business operates — no workarounds, no unused features, no vendor dependency. |

What Affects Scope, Timeline, and Cost
Complexity of the Data Model
Simple CRUD applications with a few entities are much faster to build than systems with complex relational data, calculation-heavy business logic, or real-time requirements. We assess data complexity explicitly during scoping.
Number of Integrations
Each third-party integration adds time proportional to how well-documented the external API is and how complex the data mapping between systems needs to be. We scope each integration individually.
User-Facing vs. Internal
Internal tools used by your own team require functional UI — not necessarily polished visual design. Client-facing products and SaaS MVPs require full visual design, which adds time and cost to the project.
Existing Systems to Integrate With
Connecting to modern, well-documented APIs is straightforward. Connecting to legacy systems, undocumented internal databases, or ERPs with limited API support is significantly more complex and must be scoped carefully.
Future Maintenance Plan
Software that is handed over to your own development team requires more documentation and knowledge-transfer time than software we continue to maintain. We scope the handover accordingly.
Frequently Asked Questions
How do you price custom software projects?
We price based on a fixed scope document agreed before development begins. The scope defines every screen, data entity, integration, and user role in the first release. Because scope is fixed, the price is fixed — no hourly billing surprises. Projects in our range are typically €5,000–20,000 for a focused first version. If the scope changes after sign-off, we quote the change separately before building it.
How long does a custom software project take?
A well-scoped internal tool or small SaaS MVP typically takes 4–10 weeks from scope sign-off to production deployment. Timeline depends on complexity: number of data entities, integrations required, and whether the project needs full visual design. We provide a specific timeline during the scoping phase — not a range estimate.
Who owns the code after the project?
You do. We transfer the full source code, database schema, and deployment configuration to you at handover. There are no licensing fees, no ongoing platform costs to us, and no lock-in of any kind. You can continue development with us, with your own team, or with any other developer.
What technologies do you use for custom software?
Our default stack is Next.js with TypeScript for the application layer, PostgreSQL or a suitable database for persistence, and Google Cloud Run for deployment. We choose technologies for maintainability and readability — so the developer who inherits the project six months from now can understand it without asking us.
Can you integrate with our existing systems?
Yes, provided the existing system has a documented API or a database we can connect to. We assess integration complexity during scoping. Well-documented REST APIs are straightforward. Legacy systems without APIs require more investigation and are priced accordingly.
What happens if requirements change after development starts?
Changes to the scope document are handled as formal change requests — we scope the change, quote it, and both parties agree before any new work begins. This is not a bureaucratic hurdle; it is the mechanism that keeps the original delivery date reliable and prevents the scope creep that causes most software projects to overrun.
