System Integration Services

System Integration That Unifies Your Stack

Growth stalls when CRM, ERP, billing, and custom apps disagree. Tekvers builds API bridges, sync jobs, and middleware so data flows with clear ownership.

We map fields, error handling, and cutover plans so integrations survive production—not just a happy-path demo.

What We Deliver

Concrete capabilities included in a typical system integration services engagement.

  • API design, middleware, and legacy bridges
  • ERP, CRM, and third-party connectivity
  • Data sync, mapping, and error handling
  • Integration testing and production cutover support

Why Tekvers

  • Senior engineers and domain specialists—not a revolving bench of juniors.
  • Transparent delivery with demos, documentation, and handoffs your team can maintain.
  • Production experience across 3+ relevant engagements in our portfolio.
  • Pragmatic architecture: ship value early, then expand without rewriting the foundation.

Our Process

A structured delivery model from discovery through launch and ongoing support.

  1. Discovery & scope

    Stakeholder workshops, backlog prioritization, and a delivery plan with milestones your team can track.

  2. Design & architecture

    UX flows, technical architecture, and integration design—validated before build velocity ramps up.

  3. Build, QA & launch

    Sprint delivery with demos, test coverage on critical paths, and production deployment with documentation.

  4. Support & iteration

    Post-launch monitoring, training, and a roadmap for the next phase of features or scale.

Relevant Case Studies

Production projects from our portfolio that demonstrate how we deliver system integration services for real businesses.

  • WooCommerce Integration Layer case study preview

    Commerce middleware / API bridge

    WooCommerce Integration Layer

    Challenge: Ad-hoc WooCommerce REST calls from scripts are brittle and risk exposing consumer keys. Operators needed a thin server layer that keeps store URL + consumer key/secret in environment variables. Without a coherent commerce middleware / api bridge foundation, WooCommerce Integration Layer stakeholders faced fragmented tools, slow handoffs, and limited visibility—classic failure modes Tekvers designs against.

    Solution: WooCommerce Integration Layer: Small TypeScript Express proxy forwarding product, order, and customer CRUD to WooCommerce REST wc/v3—unused CRA dashboard scaffold included. Safer pattern for server-side WooCommerce access. Tekvers delivered a maintainable commerce middleware / api bridge system for WooCommerce Integration Layer using Express, TypeScript, @woocommerce/woocommerce-rest-api, dotenv, with phased rollout, operator workflows, and documentation suited to long-term ownership.

  • Zallo case study preview

    Multi-product enterprise suite

    Zallo

    Challenge: Appointment businesses lose bookings when phones go unanswered; operators also need modular back-office SKUs instead of a single legacy monolith release train. Without a coherent multi-product enterprise suite foundation, Zallo stakeholders faced fragmented tools, slow handoffs, and limited visibility—classic failure modes Tekvers designs against.

    Solution: Zallo: Gateway-led suite—production multi-tenant AI receptionist (zallo.ai) plus NestJS/Next ERP-style SKUs (CRM, POS, finance, HRM, inventory, CMS) with shared portal UI. End-to-end receptionist loop: answer → book → SMS follow-up. Tekvers delivered a maintainable multi-product enterprise suite system for Zallo using NestJS, Next.js, TypeScript, Supabase Postgres + RLS (REC), with phased rollout, operator workflows, and documentation suited to long-term ownership.

    Multi-tenant ERP SaaS platform

    ERP SaaS Platform

    Challenge: Enterprises needed a modular multi-tenant ERP foundation with modern admin UX, CRM/POS depth, and expandable finance/inventory/HR domains—without a risky legacy monolith or premature microservice sprawl. Without a coherent multi-tenant erp saas platform foundation, ERP SaaS Platform stakeholders faced fragmented tools, slow handoffs, and limited visibility—classic failure modes Tekvers designs against.

    Solution: ERP SaaS Platform: Full-stack multi-tenant ERP—ASP.NET Core 9 Clean Architecture API with React/Vite admin; Core, Admin, CRM, POS, and additional domain modules on SQL Server with GraphQL + REST. Enterprise-shaped multi-tenant ERP foundation with a shipping CRM/POS core. Tekvers delivered a maintainable multi-tenant erp saas platform system for ERP SaaS Platform using ASP.NET Core 9, React 18, TypeScript, Vite, with phased rollout, operator workflows, and documentation suited to long-term ownership.
