Custom software development, scoped and built by the same developer.
Credantic is a custom software development company for businesses whose work no longer fits a spreadsheet or an off-the-shelf product. The person who scopes your software is the person who writes it, and you own the source code at handover.
What we build
Business software that matches how your team actually works: internal tools, client-facing portals, scheduling and job tracking, document workflows, and the integrations that connect them to the systems you already pay for.
If an existing product does 90 percent of the job, we will tell you, and help you configure it instead of building from scratch.
Related work: mobile app development for apps on phones, technology consulting for an architecture review before you commit, and AI automation services for adding AI to the software you run.
Typical projects
- Internal tools that replace spreadsheets and email chains
- Client portals with sign-in, documents and invoices
- Workflow and approval systems
- Reporting dashboards over data you already have
- Integrations between accounting, CRM and line-of-business systems
How a project runs
Every project follows the same four stages, written into the scope before any invoice.
From first call to support
- Discovery and requirements: we map the process, the users and the data, and write down what success looks like
- Design and development: short iterations you can see and test, not a big reveal at the end
- Testing and quality assurance: automated tests for the parts that matter and a review with your team before launch
- Deployment and ongoing support: we deploy to infrastructure you control and agree a support arrangement in writing
Technologies we work with
We pick technology for how long it will be supported and how easy it is for someone else to maintain, not for novelty.
Our usual stack
- C# and .NET (ASP.NET Core, Blazor)
- Python services and automation
- PostgreSQL and SQL Server
- JavaScript and TypeScript front ends, Bootstrap
- Docker, Linux and self-hosted infrastructure
- WordPress where a content site is the right answer
Is custom software the right choice for your business?
Often it is not. Custom software earns its cost when your process is specific to you, when several off-the-shelf tools have to be stitched together by hand, or when the workflow and the data are an asset you want to own. If a product on the market already fits most of how you work, buying it is usually faster and cheaper to start. The table sets out how the three routes differ.
| Factor | Off-the-shelf product | Configure an existing platform | Custom software |
|---|---|---|---|
| Fit to your process | You adapt to the product | Close after configuration, within the platform's limits | Built around your process |
| Cost pattern | Recurring subscription, usually per user | License or subscription plus setup work | Up-front build, then hosting and support |
| Ownership | The vendor owns the software and you rent access | The vendor owns the platform; you own your configuration and data | You own the source code, the data and the deployment |
| Time to first use | Shortest | Moderate | Longest, but built in stages you can use early |
| Lock-in | Depends on how easily you can export your data | Tied to the platform | Low, if you hold the code and the documentation |
| Best when | Your process is common and the product fits | A platform covers most needs and only needs tailoring | No product fits, or the workflow is part of your advantage |
We will tell you plainly when the first or second column is the better answer. Weighing that choice is part of technology consulting, and it can be a short engagement of its own. If the software is a product you plan to sell by subscription, see SaaS development. To add AI to software you already run, see AI integration services. Background reading: custom software vs. off-the-shelf: how to decide.
When should you not hire us for custom software?
- An existing product already does about 90 percent of the job. Buy it and spend the difference on configuration.
- You need a large team building many parts in parallel, or round-the-clock operations staff. We are a small firm, and the person who scopes your project is the person who builds it.
- The result must be certified by a licensed professional. We cannot provide that sign-off.
- You are choosing on the lowest hourly rate alone. We price a defined scope and a clean handoff.
What do you get at each stage of a custom software project?
Every stage ends with something you can read, run or approve, so you are never waiting for a big reveal.
- Discovery: a written scope listing the users, workflows, data and integrations, what is out of scope, and how success is judged.
- Design: clickable mock-ups, a data outline and a list of decisions you have signed off.
- Development: working software in short iterations on a test site, with the source code in a repository under your account.
- Testing: automated tests for permissions and calculations, and a review with your team before launch.
- Launch: deployment to infrastructure you control, a rollback plan, and data migration where it is in scope.
- Handover: operations documentation, a walkthrough for your team, and a written support arrangement.
What drives the cost of custom software?
We do not publish prices, because the same label covers very different projects. The size of a quote follows a short list of factors:
- The number of screens and distinct workflows
- The number of user roles and the permission rules between them
- Integrations with other systems, and how good their interfaces are
- Data to be migrated from spreadsheets or an older system
- Reports, exports and documents the software must produce
- Security, audit and availability requirements
- Hosting, backups and how long you want support
You receive either a fixed price for a defined scope or a clear rate with a ceiling, in writing, before any work is invoiced. The scope also states what is not included, so a change is a conversation and not a surprise. For a deeper guide, read how much custom software development costs.
What are the main risks, and how do we reduce them?
- Scope grows quietly. We keep a written scope and a short list of deferred items, and every change is agreed before it is built.
- The software matches the spec but not the work. Your team uses early versions on real tasks, so problems show up within weeks and not at launch.
- Only one person understands the system. The code sits in your repository with setup and operations documentation, so another developer can take over.
- Permissions are wrong and people see data they should not. Access rules get automated tests, and we walk through them with you before launch.
- Data is lost in migration. We rehearse on a copy first and agree backups and restore checks in the scope.
How do you choose a custom software development company?
Use the same checklist for every firm on your shortlist, including ours. Our own answers follow each question.
- Who writes the code? Ask for the developer's name, not only the account manager's. Here, the person who scopes your project builds it, and we do not subcontract.
- Who owns the source code and the data? It should be you, in writing. Here it is you, and the code, documentation and deployment details are handed over.
- Is there a written scope and price before work starts? Ours is a written scope with a fixed price, or a rate and a ceiling, before any invoice.
- What are the support terms after launch? Ask for them in writing. We agree support terms before launch.
- What is the exit plan? You should be able to move to another developer without a rewrite. We use mainstream technology, your repository and written documentation.
- What can the firm show you? We were formed in 2026 and have no published client case studies yet. What we can show is how we run our own systems: see how we built our client portal, an internal project. Ask every firm what it can show and what it cannot.
