Commerce Engineering
E-commerce Software Development Company
Most stores should be on Shopify. We build the ones that should not.
Custom commerce earns its cost when the catalogue, the pricing, or the integrations genuinely cannot be expressed on a platform — and not before.
Quick Answer
Updated July 30, 2026
When should e-commerce be custom-built rather than on a platform?
Custom e-commerce is justified in three situations: your catalogue or pricing model cannot be expressed on a platform (B2B contract pricing, configurable products, complex variants), integration with an ERP or fulfilment system is central to the business, or platform fees at your volume exceed a build within two to three years. Below roughly $2 million in annual online revenue, a well-built Shopify store is usually the better commercial decision, and we will say so. Where custom is right, expect $30,000–$60,000 for a storefront and pricing engine, and $20,000–$35,000 more for a mobile app.
Platform build
$6,000 – $18,000
Custom build
$30,000 – $60,000
Commerce apps shipped
Both stores
Best for
- B2B commerce with contract pricing and volume tiers
- Catalogues no platform models correctly
- Retailers whose ERP or inventory integration is the hard part
- Brands where storefront performance is a competitive advantage
Not best for
- Standard product catalogues a good Shopify theme handles
- Early-stage brands still finding product-market fit
- Teams with nobody to own the platform after launch
We have shipped commerce to both app stores — Sheopal’s runs on a shared React Native codebase across Android and iOS with Redux state and Firebase infrastructure behind it. That work is why we are comfortable saying that most stores do not need custom software.
The commerce projects that genuinely need building are the ones where the platform stops modelling the business. B2B pricing with contract rates and volume breaks. Configurable products where the variant matrix explodes. Fulfilment that depends on an ERP whose API was designed in 2009. Subscription commerce with pauses, swaps, and dunning. Those are engineering problems, and no theme solves them.
Where a platform does fit, we will build on it rather than talk you into a rebuild, and we would rather do a smaller honest project than a larger unnecessary one.

What we help with
- Headless storefronts in Next.js, built for Core Web Vitals and organic search
- Catalogue and variant modelling for products a platform cannot express
- B2B pricing engines — contract rates, tiers, volume breaks, and approvals
- Payment gateway integration with idempotent webhooks, so a retry never double-charges
- ERP, inventory, and logistics integration, including providers with awkward APIs
- Subscription commerce with pauses, swaps, and failed-payment recovery
- Native commerce apps in React Native, including store submission and release management
Comparison
Custom commerce versus a platform build
We build both, and the honest recommendation depends on maths rather than on preference.
SoftwareCrafting
- A breakeven calculation against your actual platform fees before we recommend building
- Shopify or headless recommended where it genuinely fits, even though it is a smaller project
- Checkout tested across payment methods, devices, and failure cases before launch
- Storefront performance treated as a conversion requirement, not a later cleanup
Typical Alternative
- Custom recommended regardless, because custom is the bigger invoice
- Platform limits presented as reasons to rebuild rather than reasons to configure
- Checkout tested on the happy path on one browser
- Performance discovered after the first campaign
Delivery Process
How we usually deliver this kind of build
Buyers searching for e-commerce software development company usually want clarity around how the work moves from brief to launch. This is the shape we default to unless the project needs a different engagement model.
Step 1
Scope and commercial fit
We start with the product brief, technical constraints, target users, and the fastest sensible delivery shape for this project.
Step 2
Architecture and execution plan
Before heavy build work starts, we lock the stack, delivery sequence, ownership model, and the parts that need extra operational care.
Step 3
Build, QA, and feedback loops
The same senior engineers stay close to the work through implementation, review, QA, and weekly decision-making.
Step 4
Launch and maintainable handover
We ship with documentation, deployment clarity, and a codebase your next engineer can realistically inherit.
Commercial Fit
Pricing and timeline expectations before you reach out
We do not force a fake fixed price onto every e-commerce software development company request. What we can do early is make the commercial shape and next steps clear enough for a real buying decision.
- Written proposal in 24 hours for qualified briefs
- Kick-off readiness in 48 hours once scope is aligned
- Fixed-scope or dedicated-pod engagement depending on clarity
- NDA and IP ownership handled before technical depth is shared
Most serious conversations start with a short project brief, inherited codebase context, or delivery bottleneck. From there we recommend the lightest viable commercial shape instead of trying to upsell a bigger team than the work needs.

FAQ
Questions buyers ask before they reach out
Should we use Shopify or build custom e-commerce?
+
Shopify unless you have a specific reason not to. Custom is justified when platform fees at your volume exceed the build within two to three years, when your catalogue or pricing genuinely cannot be modelled, or when deep ERP integration is central to the business. Below about $2 million in annual online revenue the maths rarely works.
What does custom e-commerce development cost?
+
$30,000–$60,000 for a custom storefront with a catalogue and pricing engine, $18,000–$36,000 for headless commerce on an existing backend, and $6,000–$18,000 for a platform build with real customisation. A mobile app adds $20,000–$35,000.
Do we need a mobile commerce app?
+
Only for repeat-purchase categories where customers buy often enough to justify installing one. For considered, infrequent purchases a fast responsive storefront converts as well and costs $20,000–$35,000 less. We have built commerce apps for both stores and still say this.
Can you integrate with our ERP or inventory system?
+
Yes. Cost here is driven almost entirely by the quality of the other system’s API rather than by anything on our side, so we scope integrations separately once we can see what it actually exposes. Older ERPs frequently need an adapter layer that absorbs their quirks in one place.
Can you handle B2B pricing rules?
+
Yes — contract pricing, customer-specific rates, volume tiers, approval workflows, and quote-to-order flows. This is the single most common reason a business genuinely outgrows a platform, because no theme models it well.
Will the site rank on Google?
+
We build the technical foundation — server rendering, product structured data, correct canonicals, sitemaps, and Core Web Vitals — which is necessary and not sufficient. Rankings also need content and authority over time, and any agency promising rankings from a build alone is overselling.
