Custom Software Development for E-commerce and Online Stores

POLPROG builds custom software for e-commerce businesses that have outgrown off-the-shelf platforms. We design, build, and integrate the systems your store needs to sell more and operate with less friction.

When a standard platform stops fitting your store

Most online stores start on a ready-made platform, and for a while it works. The trouble begins when your catalog, pricing rules, fulfilment, or reporting grow more specific than the template allows. You end up paying for plugins that almost fit, exporting spreadsheets by hand, and reconciling orders across tools that were never meant to talk to each other.

  • Manual steps between your store, warehouse, and accounting that eat staff time every day
  • Pricing, bundling, or B2B rules the platform cannot express without ugly workarounds
  • Slow checkout or product pages that quietly cost you conversions
  • Data scattered across the shop, marketplaces, and back office with no single source of truth

How POLPROG helps

We build software around how your business actually sells, not the other way around. That can mean a custom storefront feature, a headless commerce front end, an internal tool for your operations team, or the integration layer that ties your shop to the systems you already run. We work with your existing stack where it makes sense and replace only what is holding you back, so you avoid a risky full rewrite. Our custom software development service covers the whole path from scoping to launch and ongoing support.

  • Custom storefront and checkout features tailored to your products and customers
  • Headless or hybrid front ends for faster, more flexible shopping experiences
  • Integrations with ERP, CRM, warehouse, payment, shipping, and marketplace systems
  • Internal dashboards and admin tools for orders, inventory, and pricing
  • Automation that removes repetitive manual work from your team

What you get

You get working software you own outright, built to fit your processes and ready to grow with your sales volume. Every project ships with clean, documented code and a clear handover so you are never locked in.

  • Full ownership of the source code and all related assets
  • A maintainable codebase with documentation your future developers can read
  • Integrations that keep orders, stock, and customer data in sync automatically
  • A solution sized to your real traffic and seasonal peaks
  • Support and iteration after launch as your store evolves

How we work

We keep the process transparent and incremental so you see value early and stay in control of scope and budget. We start by understanding your store, your numbers, and the bottlenecks that matter most, then build in focused stages with regular check-ins. If you are weighing a tailored build against a packaged tool, our guide on custom software versus off-the-shelf solutions is a useful starting point.

  • Discovery: we map your sales flow, systems, and priorities
  • Proposal: a clear scope, timeline, and fixed direction before any code
  • Build: short iterations with working software you can review
  • Launch: testing, deployment, and a complete handover
  • Support: ongoing improvements as your business grows

Frequently asked questions

How much does custom e-commerce software cost?
It depends on scope. A focused integration or single feature is a much smaller project than a full headless storefront. After a short discovery call we give you a clear scope and a realistic estimate, so you can decide before any development starts. We size the work to your priorities rather than selling a fixed package.
How long does a project take?
Smaller integrations and tools often ship in a few weeks, while larger builds run over several months in stages. We deliver in short iterations, so you see working software early rather than waiting until the very end. We agree a timeline with you up front and keep you updated throughout.
Do I own the code you build?
Yes. You receive full ownership of the source code and all related assets, along with documentation and a clear handover. There is no lock-in: another team could pick up and maintain the codebase if you ever needed them to.
Can you work with my existing store and systems?
Usually yes. We integrate with common e-commerce platforms, ERPs, CRMs, payment providers, and shipping and marketplace APIs. Where your current setup works well we build on it, and we replace only the parts that are holding your business back rather than forcing a full rewrite.
What technologies do you use?
We choose the stack to fit the job rather than forcing one toolset on every project. For e-commerce work that commonly means modern web frameworks, well-documented APIs, and reliable databases. We favor mature, maintainable technology so your software stays supportable for years.
