Shopify Services

Shopify is a hosted commerce platform, which means the checkout, payment handling, PCI scope and hosting are the platform's responsibility and not yours. What is left for a build team is the storefront, the custom logic, and the connections to everything else in the business. Themes are built with Liquid and section-based layouts, the admin and Storefront APIs allow a fully custom or headless front end, apps extend the platform without forking it, and checkout is extended through supported extension points rather than by editing it directly.

Iseyon builds and integrates on that surface. Our work is the store, the apps behind it, the data flowing between Shopify and your ERP, CRM and analytics stack, and the migration to get there.

Store Design & Development

Shopify Store Design and Development

Iseyon builds responsive storefronts around the path a customer actually takes to purchase: collection and search behavior, product page structure, cart and checkout flow, and the merchandising controls your team will use afterwards. Themes are built with sections so merchandisers can change layout without a developer. Performance is a design constraint from the start, since image weight, third-party scripts and app bloat are the usual reasons a fast theme becomes a slow store.

Custom Shopify App Development

Iseyon develops custom apps where a business rule has no off-the-shelf equivalent: pricing and discount logic, inventory and vendor workflows, subscription or fulfillment behavior, and integrations with internal systems. Apps are built against Shopify's APIs and webhooks with idempotent handling, retries and rate limit awareness, so a delayed or repeated webhook does not corrupt order state. We prefer a supported extension point over a theme hack every time, because theme hacks do not survive the next platform update.

Payment Gateway and Checkout Integration

Iseyon configures payment and checkout for the market you sell in, including gateways such as Razorpay, Stripe and PayPal, multi-currency and local payment methods, and checkout customization through supported extensions. Where the commercial model needs it, we implement split payments, multi-vendor payouts, and tax and compliance handling for the regions involved. Sensitive card data stays inside the platform's scope, which is a large part of why merchants choose Shopify in the first place.

Multi-Vendor and Marketplace Solutions

Iseyon builds marketplace models on Shopify: vendor onboarding and permissions, product ownership mapping, commission and fee calculation, split fulfillment and order routing, vendor-facing reporting, and payout automation. The hard part is rarely the storefront. It is reconciling what each vendor is owed against what was actually shipped and refunded, so we design that reconciliation first.

Automation, Integration & Support

Automation and Workflow Optimization

Iseyon automates the operational work that scales badly by hand: order routing and tagging, inventory synchronization, refund and cancellation handling, fraud and exception review queues, and vendor settlement runs. Each automation is built with a visible audit trail and a manual override, because an automated process nobody can inspect or interrupt becomes its own operational risk.

Integration Services

Iseyon connects Shopify to ERP, CRM, warehouse and analytics systems so product, inventory, order, customer and financial data stay consistent across them. That means agreeing which system owns each field, handling failures with retry and reconciliation rather than assuming delivery, and making the sync state observable so a mismatch is caught before finance finds it at month end.

Performance, SEO and Security

Iseyon works through what makes a storefront slow: image handling, script and app audit, theme code, caching behavior and third-party tag load. On SEO we cover crawlable structure, canonical and pagination handling, structured data for products, and safe redirect mapping. On security, we scope app permissions to what is needed, review third-party apps before installing them, and keep secrets out of themes.

Migration and Store Modernization

Iseyon migrates from legacy platforms with the data reconciled rather than merely copied: products and variants, customers, order and refund history, discount structures, URL redirects to preserve search equity, and payment and tax configuration. Migrations run with a rehearsed cutover, a rollback plan and a reconciliation step comparing source and destination records before the old store is retired.

Ongoing Support and Maintenance

Iseyon provides monitoring, app and theme updates, incremental improvements and support against agreed response expectations. Where a client wants to run it internally, we hand over documented theme and app code, integration runbooks, and training for the merchandisers and operators who use the admin daily.
