Which ERP systems have you worked with?

I have integrated with the Uyumsoft ERP. For another system I first need to read its documentation and API, then I can tell you whether it is feasible.

Which payment providers can you integrate?

I have integrated QNBPay and Stripe. For other providers I review the API documentation and tell you whether it fits.

Is ready-made e-commerce software or custom development better?

For a standard store, ready-made software is usually cheaper and faster. Custom development makes sense when you have a special ERP flow or B2B rules. I listen to your needs and tell you honestly which one fits.

E-commerce store and ERP integration

Short answer

For Harmoni Yazılım I build Next.js e-commerce stores and React/Vite B2B management apps integrated with the Uyumsoft ERP. Stock, order and customer flows talk to the ERP, and payments go through QNBPay. I have also worked on Boyner's product pages and seller panel. If you want a store that works with your ERP or accounting software, message me.

What I do

E-commerce stores with product, cart, payment and order flows
B2B apps with dealer-specific pricing and ordering screens
Matching stock, order and customer data with an ERP
Payment provider integration and 3D Secure verification flows
Technical SEO and Google Search Console setup

What matters in an ERP integration

The store and the ERP each hold the same stock and the same orders. To avoid conflicts, you need to decide up front which system owns which data. I settle that in the first conversation, because fixing it later is the most expensive part.

Similar work I have done

Harmoni Yazılım: an after-sales app with service request tracking, repair records, photo upload and OTP-verified delivery.
Boyner (via PATH): product listing and detail pages, plus coupon, notification and order management in the seller panel.
