Project overview

360TravelSIM - eSIM Sales, Client and Reseller Platform

A connected eSIM commerce ecosystem with three Next.js applications, a Golang API, online payments and integrations with an eSIM supplier and ERP.

360TravelSIM was built as more than a sales website. The solution combined a public eSIM storefront, separate customer and reseller portals, a Golang integration layer, supplier fulfilment, Stripe payments and ERP-connected operational workflows. The commercial program is no longer active, although the public sales website remains online.

01
Direct sales

Next.js eSIM storefront

The public frontend presented destinations and data bundles, supported search-friendly product discovery and guided travellers into the online purchase flow.

  • Country and bundle discovery
  • Conversion-focused purchase paths
  • Stripe online payment entry points
02
Customer self-service

Next.js client portal

Customers used a dedicated application for their account, orders and purchased eSIM services rather than relying on the public storefront for post-sale support.

  • Account and order access
  • Purchased eSIM service context
  • Separated authenticated customer workflows
03
Partner sales

Next.js reseller portal

A separate reseller and affiliate application supported partner registration, attributed sales and commission-oriented workflows.

  • Reseller and affiliate accounts
  • Partner sales attribution
  • Commission-oriented programme workflows
04
Operations and integrations

Supplier API, ERP and Stripe

The Golang backend connected the web applications with the external eSIM supplier, online payments and internal ERP records.

  • External eSIM catalogue and fulfilment integration
  • Stripe payment status and order handling
  • ERP-connected sales and operational records

Connected commercial workflow

From destination search to fulfilment and partner attribution

The platform kept the customer purchase, supplier integration, back-office record and reseller context within one traceable flow.

1

Discover

A traveller selected a destination and matching eSIM bundle in the public Next.js storefront.

2

Pay

Stripe handled online payment while the platform preserved the order and customer context.

3

Fulfil

The Go API exchanged product and order data with the external eSIM supplier and customer portal.

4

Operate

ERP records and reseller attribution connected sales, service delivery and affiliate workflows.

Built as an operating platform, not a standalone storefront

The project separated public sales, customer self-service and reseller work into dedicated Next.js applications, with Golang coordinating the commercial and telecom integrations behind them.

These screenshots were captured from the live public website and portal login pages. The commercial eSIM and reseller programme is no longer active, but these interfaces remain online as a record of the delivered system.

The public sales frontend introduces the global eSIM offer and starts product discovery from a destination selector.

The affiliate page directed partners into the separate reseller registration and login flows.

A separate client portal provided the authenticated post-sale entry point for customer accounts and eSIM services.

The reseller portal separated partner and affiliate workflows from the customer-facing application.

Challenge

Keep the external supplier catalogue, eSIM order state and ERP records aligned across the sales and post-sale journey.

Serve public buyers, existing customers and resellers through separate applications without fragmenting the underlying business logic.

Connect Stripe payments and affiliate attribution with orders, fulfilment and operational records.

Approach

Delivered three focused Next.js applications: the public eSIM storefront, customer portal and reseller portal.

Centralised authentication, products, orders and integration workflows in a Golang REST API connected to the eSIM supplier and ERP.

Implemented Stripe payments together with partner registration, sales attribution and affiliate programme workflows.

Outcomes

An end-to-end sales path connected product discovery, online payment, supplier fulfilment and customer self-service.

Customers and resellers received dedicated portals tailored to their roles instead of sharing one overloaded interface.

The live public surfaces remain an online record of the delivered platform even though the commercial programme has ended.
