E-Commerce Website Development
High-converting e-commerce stores powered by Fonvio.

E-Commerce Website Development: how it works
In e-commerce the difference isn't getting a product into the cart — it's getting it bought, bringing the customer back and keeping operations breathing. At Saybes we build your store on Fonvio, our own e-commerce platform, and optimise every step from design to payment and shipping for conversion.
Fonvio is a platform that has been running real stores for years and is natively compatible with Türkiye's payment and logistics ecosystem. Product and variant management, stock tracking, a campaign and coupon engine, e-invoice integration and multi-channel sales are all managed from a single panel.
For payments we offer instalment credit cards, bank transfer and cash on delivery through İyzico and PayTR. Integrations with carriers such as Yurtiçi, Aras and MNG automate label creation, tracking and returns.
We set up product and stock synchronisation with marketplaces like Trendyol and Hepsiburada so you sell across channels from one inventory — a sale on the marketplace updates your site instantly.
The measurement stack a store needs to grow — Google Analytics 4 e-commerce events, Meta Pixel and the Conversions API — is configured from day one. If you wish, we take over ad management after launch: we don't just open the store, we grow it.
Mat Gross, an automotive products store built on Fonvio whose advertising we manage, is one of our recent examples.
Five reasons to do this with us
The difference is in the details: how we start, what we consider standard and where we stand after launch.
Our own platform: Fonvio
No monthly commission; natively compatible with Türkiye's payment, shipping and e-invoice ecosystem.
Designed for conversion
Product page, cart and checkout steps are built to reduce abandonment.
One stock, many channels
The site runs in sync with Trendyol/Hepsiburada; no stock errors or double work.
Measurement from day one
GA4 e-commerce events, Meta Pixel and the Conversions API come set up; ad data starts clean.
The team that opens the store runs the ads
The measurement chain never breaks, the budget works more efficiently; one contact when there's a problem.
