Custom ecommerce vs Shopify: when bespoke wins
A practical comparison for selling online: complex rules, ERP hooks, B2B workflows, internal marketplaces. Learn when SaaS is enough and when you need dedicated engineering.
“Platform store or custom build?” SaaS solutions are perfect for many businesses. Custom ecommerce makes sense when your operating rules don’t fit the default playbook.
When an off-the-shelf platform is enough
- Straightforward catalogue, simple pricing, standard shipping and payments.
- No deep sync with ERP, multi-warehouse stock, or negotiated B2B price lists.
- You need to launch fast with predictable monthly costs.
Signals you need custom (or heavily tailored) work
- Customer-specific pricing, regions, contracts, or volume tiers.
- B2B flows: approvals, net terms, recurring orders with custom logic.
- Real-time integrations with ERP, WMS, CRM, invoicing, external marketplaces.
- Non-standard product logic (configurators, dynamic bundles, compatibility rules).
Forcing brittle plugins for core revenue operations often costs more than a focused module.
Questions to clarify in discovery
- What are the top five daily actions your team performs in the store admin?
- What happens after checkout (fulfilment, carriers, returns, credit notes)?
- Which systems must exchange data without manual spreadsheets?
Pitfall
Undocumented automation that breaks on every theme/app update: insist on maintainable architecture and ownership of integrations.
Takeaway
It’s not “SaaS vs custom”: it’s fit for your operating model. Tight constraints often justify tailored software to reduce errors and manual work.
Write down catalogue shape, pricing rules, integrations (inventory, invoicing, B2B), and internal SLAs. The “platform vs bespoke” answer follows from that, not from brand names.
