Custom Software Development in Türkiye: market overview
Companies in Türkiye increasingly look offshore for custom software development. High crypto adoption, a huge e-commerce market and export manufacturers drive demand for licensed crypto platforms, marketplaces and ERP.
Demand is strongest across E-commerce, Crypto, Gaming, Manufacturing and Textiles, and every engagement is shaped by local regulation, payment habits and working hours rather than a one-size-fits-all template.

How key sectors in Türkiye use custom software development
Custom Software Development for E-commerce
E-commerce businesses in Türkiye usually need fast storefronts, omnichannel inventory, loyalty and frictionless checkout. For them, our custom software development typically starts with customer & partner portals (self-service portals for ordering, tickets, documents and payments) and adds accounting & crm sync as the platform grows. Progress is tracked on checkout conversion and stock accuracy.
Custom Software Development for Crypto
Crypto businesses in Türkiye usually need licence-ready custody, transaction monitoring, wallet security and clear user disclosures. For them, our custom software development typically starts with multi-entity & multi-currency (one platform across subsidiaries, regions, currencies and tax regimes (VAT, GST, sales tax)) and adds dashboards & bi as the platform grows. Progress is tracked on deposit-to-trade conversion and withdrawal processing time.
Custom Software Development for Gaming
Gaming businesses in Türkiye usually need scalable game backends, player wallets, live-ops tooling and anti-fraud controls. For them, our custom software development typically starts with accounting & crm sync (two-way sync with QuickBooks, Xero, Zoho, Salesforce, HubSpot and NetSuite) and adds legacy modernisation as the platform grows. Progress is tracked on daily active players and retention day 7.
Custom Software Development for Manufacturing
Manufacturing businesses in Türkiye usually need production planning, quality traceability, machine data and supplier collaboration. For them, our custom software development typically starts with dashboards & bi (real-time KPIs on web and mobile with drill-down reporting) and adds workflow & approval systems as the platform grows. Progress is tracked on overall equipment effectiveness and scrap rate.
Custom Software Development for Textiles
Textiles businesses in Türkiye usually need production planning, quality traceability, machine data and supplier collaboration. For them, our custom software development typically starts with legacy modernisation (move VB6, FoxPro, Access or old PHP/.NET systems to a modern cloud stack without losing data) and adds customer & partner portals as the platform grows. Progress is tracked on overall equipment effectiveness and scrap rate.
Example: custom software development for a textiles business in Kocaeli
Consider a textiles company in Kocaeli (automotive and petrochemical industry). A typical custom software development engagement would start with customer & partner portals, then multi-entity & multi-currency, and finish the first release with accounting & crm sync — usually within 6–10 weeks.
Payments would run through Cards, data would be handled under KVKK, and success would be measured on overall equipment effectiveness, scrap rate and order lead time.
Example: custom software development for a e-commerce business in Ankara
Consider a e-commerce company in Ankara (government, defence and research). A typical custom software development engagement would start with dashboards & bi, then legacy modernisation, and finish the first release with workflow & approval systems — usually within 8–14 weeks.
Payments would run through BKM Express, data would be handled under KVKK, and success would be measured on checkout conversion, stock accuracy and repeat-purchase rate.

Regulators that can shape custom software development in Türkiye
Depending on your product, these authorities may set requirements that affect custom software development:
BDDK
Türkiye's Banking Regulation and Supervision Agency, which licenses banks and supervises IT and data-localisation rules. For custom software development, payment licensing, safeguarding of client funds and operational resilience are the usual focus.
CMB (crypto asset service providers)
The Capital Markets Board of Türkiye, which licenses crypto-asset service providers under 2024 legislation. For custom software development, the key questions are whether any token, investment or trading feature is regulated and how investors are protected.
CBRT
The Central Bank of the Republic of Türkiye, which licenses payment and e-money institutions and runs the FAST instant-payment system. For custom software development, payment licensing, safeguarding of client funds and operational resilience are the usual focus.
Payment rails we integrate in Türkiye
FAST
An instant-payment system — in Türkiye run by the CBRT, and in Singapore operated for interbank transfers — used for invoice collection with automatic matching to orders.
TROY
Türkiye's domestic card scheme — used for invoice collection with automatic matching to orders.
Cards
Debit and credit cards, accepted via global and local acquirers — used for invoice collection with automatic matching to orders.
BKM Express

KVKK: compliance checklist for custom software development
Before launch in Türkiye, we work through this checklist with your team and advisers:
- Map every personal-data field to a lawful purpose under KVKK.
- Decide where data is hosted and whether data about Türkiye customers must stay in-region.
- Implement consent records plus data-subject access and deletion workflows.
- Encrypt data in transit and at rest; restrict and log administrative access.
- Prepare a breach-notification procedure that meets the timelines that apply in Türkiye.
- Review contracts and data-processing agreements for every third-party service.
Hosting and data residency for custom software development in Türkiye
For clients in Türkiye we usually host on Local Turkish data centres or nearby EU regions, subject to data-transfer rules. The choice balances latency for local users, KVKK requirements on where personal data may be stored or transferred, and any sector rules your regulator sets. Backups and disaster-recovery copies follow the same residency decision.
