Gartner projects that 80% of B2B sales interactions between suppliers and buyers will happen in digital channels.
Baymard Institute puts the average online cart abandonment rate near 70%, most of it caused by checkout friction.
Statista reports that mobile devices now account for roughly 60% of ecommerce sales worldwide, and the share keeps rising.
Shopify is the right answer for most online stores, and Tepia says so plainly. A custom online store is justified when the way you sell is different from the way a template assumes you sell.
Many of these are not replacements for Shopify at all; they are a custom front end or a custom layer on top of it.
The decision framework with fee math is on the Shopify vs custom online store page.
Tepia has built all three patterns and picks by trigger, not by preference.
Tepia’s rule: keep checkout on the platform as long as possible, because checkout is where fraud, taxes, payment methods and compliance live and the platforms handle them well. Move it only when your payment terms (net 30, purchase orders, partial shipments) make platform checkout impossible.
Tepia’s RELI Solutions work, a home improvement app for window and door replacement, is an example of a configured product sold through an app.
Subscriptions with real rules. Subscription apps handle a fixed box every month.
Checkout steps no plugin provides. Age or license verification, delivery slot selection, installation scheduling, financing application, or regulatory disclosures that must be acknowledged before purchase. Tepia builds these as steps in a custom checkout or as a pre checkout flow that hands off to platform checkout.
Every custom store Tepia builds meets WCAG 2.1 AA accessibility, scopes PCI DSS down to tokenized payments through Stripe or Square so you never store card data, and handles customer data under CCPA and GDPR rules, which matters for California and international customers.
Tepia’s six phase process applies to every store build, with discovery deciding the architecture before any design work.
The process is documented at tepia.co/process, and finished products are at our work.
