Custom Software Development for Small Businesses and Startups
Off-the-shelf software makes you work its way. Custom software works yours. Pixiilab designs and builds web applications, SaaS products, mobile apps and integrations for startups and growing businesses that have outgrown spreadsheets, manual work and tools that don't talk to each other.
Because design and development sit in the same team, the software we ship is not just functional — it's something your customers and staff actually enjoy using.

Problems custom software solves for small businesses
If you have typed any of these into Google, you are in the right place.
The business runs on spreadsheets and copy-paste
A custom application with one source of truth, validation and permissions, so the data is right and nobody re-types it.
Tools that don't talk to each other
APIs and integrations that connect your store, CRM, accounting and payment tools, so data flows automatically.
Generic software forces generic workflows
Software built around how your team actually works, instead of a template you have to bend to.
Unclear scope and runaway budgets
A discovery phase that produces a fixed scope, fixed price and timeline before any code is written.
Hours lost to manual, repetitive work
Automations and internal tools that remove the manual steps, with monitoring so they keep running.
What's included
Every engagement is scoped to your goals — here's where we typically start.
Custom web applications
Portals, dashboards and internal tools that replace spreadsheets and manual work.
SaaS products
From MVP to scale: multi-tenant apps with billing, auth and admin built in.
MVP development
The smallest product worth launching, shipped in weeks and built to grow.
APIs & integrations
Connect your store, CRM, ERP and payment tools so data flows automatically.
Software Development samples

MVP Development
The smallest product worth launching, scoped, designed and shipped in weeks — with the foundations to grow into the full product.
Software built around your business, not the other way round
Most software projects go wrong before any code is written: unclear scope, features nobody needs, and decisions made without users. We start with discovery and clickable prototypes so you can see and test the product before committing to the build.
We then build in short iterations, shipping working software every couple of weeks so you can give feedback early, change priorities and avoid expensive surprises at the end.
What you get
- Product discovery, scope and roadmap
- UX/UI design and clickable prototypes
- Custom web and mobile application development
- APIs and third-party integrations
- Deployment to Vercel, AWS, Google Cloud or your own VPS, with monitoring
- Source code, documentation and post-launch support

Software Development questions, answered
What is custom software development?
It's designing and building software specifically for your business — your workflows, customers and data — instead of adapting your business to a generic off-the-shelf product.
How much does custom software cost?
It depends on scope: the number of features, user types, integrations and platforms. We start with a discovery phase that produces a clear scope and estimate, so you know the cost before the build begins.
How long does it take to build?
A focused MVP is usually a matter of weeks to a few months; larger platforms are delivered in phases. We'll give you a timeline with your estimate.
Who owns the code?
You do. On final payment you own the source code and we hand over repositories, credentials and documentation.
Can you work on our existing software?
Yes. We can audit, maintain and extend existing applications, or modernise them in stages without stopping your business.
Where will the software be hosted?
Wherever fits the system: Vercel for most web apps, AWS or Google Cloud for larger platforms and background workloads, or a VPS you control. We set up deployment, monitoring and backups, and hand over the accounts so you own the infrastructure.
