Built around your market

Engineering built around
how Türkiye does business.

Card instalments at every checkout and FAST transfers in seconds. e-Fatura, e-Arşiv and e-İrsaliye on every sale. Brands selling on Trendyol, Hepsiburada and abroad at once. European buyers asking for traceability and, now, carbon data. Prices and costs that move with the lira. A Riviera season that fills resorts in weeks. A Monday to Friday week only 2.5 hours behind India. We design around these realities from the first workshop.

Questions from businesses in Türkiye

Frequently asked questions

Do you work with Turkish businesses remotely?

Yes. Delivery runs remotely from India, with local partner collaboration where agreed. India is 2.5 hours ahead of Türkiye, so most of your Monday to Friday working day overlaps with ours.

Which currency do you invoice in?

Commercial terms and invoicing currency, Turkish lira, euros or US dollars, are agreed in the written proposal for each project.

Do you build in Turkish?

Yes. Interfaces, documentation and AI assistants can be delivered in Turkish and English. Project leadership is in English, with Turkish support where agreed.

Can you connect our ERP to e-Fatura?

Yes, through the GİB-authorised special integrator your business uses. Registration, tax filings and advice remain with your business and its mali müşavir.

Can our data stay in Türkiye?

Where required, we design for hosting in Türkiye and follow KVKK, including cross-border transfer rules, together with your compliance team.

How does a project start?

With a short discovery call about one workflow, then a written scope with outcomes, responsibilities and fees before any build begins.
