Shopify Integration: Build a Storefront That Runs Itself
Your Shopify store should be a growth engine, not a daily firefight of manual order updates, mismatched stock levels, and disconnected systems. At NexaFlow Systems, we build deep, reliable Shopify integrations that connect your storefront to the tools that actually run your business — ERP platforms, warehouses, accounting software, shipping carriers, and marketing systems.
What we build
- Order automation — orders flow from Shopify to your ERP, fulfillment, and accounting systems in real time, eliminating double entry and human error.
- Inventory sync — multi-warehouse and multi-channel stock levels stay accurate across Shopify, marketplaces, and back-office systems.
- Custom Shopify Apps — private and public apps tailored to your workflows, built on the latest Shopify Admin API and Storefront API.
- Headless commerce — fast, custom storefronts powered by Shopify on the backend with React, Next.js, or your preferred frontend stack.
- Migration & data sync — clean migrations from Magento, WooCommerce, or legacy carts without losing customer data, SEO, or order history.
Why businesses choose us
We don't bolt on a generic connector and walk away. Every Shopify integration we deliver is mapped to your real business processes — your SKUs, your tax rules, your fulfillment logic, your reporting needs. The result: fewer tickets, faster fulfillment, and a Shopify store that scales without scaling your operations team.

Stripe Integration: Payments, Subscriptions, and Revenue Automation
Stripe is the most powerful payments platform on the planet — but its real value only shows up when it's wired correctly into your product, your billing model, and your finance stack. NexaFlow Systems builds Stripe integrations that go far beyond a checkout button: secure subscription billing, usage-based pricing, automated invoicing, and reconciliation pipelines that finance teams trust.
What we build
- Checkout & payment flows — Stripe Checkout, Payment Intents, and custom card forms with full PCI-compliant tokenization.
- Subscription billing — recurring plans, trials, proration, dunning, coupons, and tiered or usage-based pricing using Stripe Billing.
- Marketplaces & payouts — Stripe Connect implementations for platforms paying out to vendors, freelancers, or partners.
- Webhook & event pipelines — reliable, idempotent webhook handlers that keep your database, CRM, and ERP in sync with Stripe events.
- Reconciliation & reporting — automated mapping of Stripe payouts to your accounting system, with audit trails finance teams can sign off on.
Why businesses choose us
Payment bugs aren't ordinary bugs — they cost real money and damage customer trust. We design Stripe integrations defensively: idempotent operations, retry-safe webhooks, full logging, and edge-case handling for failed cards, disputes, refunds, and tax. Your revenue keeps flowing even when networks blip.

ERP Integration: One Source of Truth Across Your Business
An ERP that doesn't talk to your storefront, warehouse, or accounting system isn't an ERP — it's an expensive spreadsheet. NexaFlow Systems specializes in ERP integrations that turn fragmented data into a single, real-time source of truth across sales, inventory, finance, and operations.
What we integrate
- Shopify ↔ ERP — bidirectional sync of products, orders, customers, inventory, and fulfillment status with SAP, NetSuite, Microsoft Dynamics, Odoo, Tally, Zoho, and custom ERPs.
- Warehouse & inventory systems — barcode scanning, bin locations, cycle counts, and real-time stock visibility across multiple warehouses.
- Procurement & supplier workflows — automated purchase orders, supplier portals, and lead-time tracking.
- Finance & accounting sync — journal entries, tax reports, and invoice automation to QuickBooks, Xero, Tally, or your ERP's finance module.
- Custom ERP modules — when off-the-shelf doesn't fit, we build modules and dashboards inside your ERP that match how you actually work.
Why businesses choose us
Most ERP integration projects fail not because of code, but because of process mismatch. We start with your operations, not your software — mapping the real flow of orders, stock, and money before writing a line of integration code. The outcome is an ERP your team trusts and uses, not one they work around.

Custom Development: .NET, SQL, APIs, and Automation
When off-the-shelf software hits its limits, custom development takes over. NexaFlow Systems builds production-grade business applications, internal tools, APIs, and automations on the Microsoft stack — designed for performance, security, and long-term maintainability.
What we build
- .NET applications — ASP.NET Core web apps, Web APIs, Windows services, and desktop tools using C#, .NET 6/7/8, and Entity Framework.
- SQL Server & database engineering — schema design, stored procedures, query tuning, indexing strategies, ETL pipelines, and reporting databases that stay fast under load.
- API development — REST and GraphQL APIs with proper authentication (OAuth2, JWT), rate limiting, versioning, and OpenAPI documentation your partners can actually use.
- Workflow automation — replace manual, error-prone processes with scheduled jobs, message queues, and event-driven workflows that run quietly in the background.
- Legacy modernization — bring old VB6, classic ASP, or aging .NET Framework applications onto modern .NET with minimal disruption.
- Cloud deployment — Azure, AWS, and Netlify deployments with CI/CD, monitoring, and cost-aware infrastructure.
Why businesses choose us
We've shipped .NET and SQL systems that quietly run mission-critical operations for years. Our code is reviewed, tested, and documented — so when your team grows or your needs change, your software keeps up instead of holding you back.
