Your business has outgrown off-the-shelf platforms
Shopify and WooCommerce are excellent until your pricing logic, catalog structure or fulfilment workflow needs something they cannot do. A custom build removes the ceiling.

When templates run out
Have you outgrown off-the-shelf ecommerce?
Custom ecommerce is not for everyone. But if any of these are true, a platform is now costing you more than it saves.
You are fighting the platform, not using it
When you spend more time working around a platform than with it, the platform is the problem. Custom ecommerce is shaped around your business, not the other way round.
Complex integrations the platform cannot handle
Deep ERP, PIM, custom logistics or proprietary system integrations often hit the limits of hosted platforms. Custom code connects to anything, cleanly.
App fees and transaction cuts eating margin
Platform fees, transaction percentages and stacked app subscriptions add up. A custom storefront removes the per-sale tax and the monthly app bill.
A shopping experience no template can deliver
Configurators, complex product bundles, dynamic pricing or unique buying flows need custom UX. Templates simply cannot deliver a truly differentiated experience.
No real ownership of your platform
On a hosted platform you rent your store and play by their rules. Custom ecommerce means you own the code, the data and the roadmap outright.

Client words
Trusted by businesses with real complexity
Our pricing has thousands of customer-specific rules no platform could handle. They built a custom storefront that does it natively. Our reps stopped quoting by hand and online orders now make up most of our revenue.
We were paying a fortune in platform and app fees and still fighting the limitations. The custom build removed both. We own the code, it scales with us, and it does exactly what we need.
Our product configurator is the heart of our business and no template could build it. Their custom platform handles it beautifully and the checkout conversion is the best we have ever had.

Questions, answered
Custom ecommerce FAQs
How much does custom ecommerce development cost?
Most custom ecommerce projects land between $20,000 and $150,000. The range is wide because custom builds vary enormously in scope. We scope and itemize precisely after a discovery phase so you know exactly what you are paying for.
When should I choose custom over Shopify or WooCommerce?
Choose custom when off-the-shelf platforms cannot handle your pricing logic, catalog complexity, integrations or buying experience, when platform and app fees are eating your margin at scale, or when ownership and control matter strategically. For most stores, a hosted platform is the better-value choice, and we will tell you so honestly.
How long does a custom ecommerce build take?
Custom platforms typically take 12 to 28 weeks depending on scope. We work in phases with a usable version early and progress demos throughout, so you see it taking shape rather than waiting for a big reveal.
Do I own the code?
Yes. Full IP assignment is standard. The code, the database, the designs and the infrastructure all belong to you, with no platform lock-in and no per-sale fees.
Can you integrate with our ERP and other systems?
Yes. Deep integration is one of the main reasons businesses go custom. We connect to ERP, PIM, WMS, accounting and proprietary systems through their APIs, however unusual, with proper sync and error handling.
Will a custom store be secure and PCI compliant?
Yes. We architect for security from the start, handle payments through PCI-compliant gateways and tokenization, and build the data controls and audit trails that regulated sectors require.
Can a custom store scale for high traffic?
Yes. We design the architecture for your expected scale, use caching, CDN and horizontal scaling, and load test before launch so the store stays fast during traffic spikes and sale events.
What technologies do you use for custom ecommerce?
Typically React or Next.js on the frontend, Node.js on the backend, PostgreSQL or MongoDB for data, Redis for caching and Algolia for search, deployed on AWS. We choose based on your requirements and long-term maintainability.
Can you go headless?
Yes. We frequently build headless, decoupling the storefront from the commerce backend so you get maximum performance and can sell across web, mobile app and other channels from one backend.
Can you rebuild our existing custom store?
Yes. We start with a paid audit of the existing codebase, then plan whether to refactor, extend or rebuild based on its condition and your goals, migrating data and preserving rankings throughout.
Do you provide ongoing development after launch?
Yes. Custom platforms are living products. Most clients keep us on a retainer for ongoing development, new features, monitoring and support, since the team that built it is fastest to evolve it.
What happens after launch?
You get documentation, architecture diagrams, a deployment runbook and a handover session. Then most clients move to an ongoing development arrangement so the platform keeps improving with the business.
