DİA vs Nilvera

DİA is a Turkish cloud ERP and accounting platform built to run in the web browser from the start rather than being a desktop product moved to the cloud. Its core job is to give small, mid-size and growing Turkish companies a single system for accounting, operations and compliance that can be accessed from anywhere.

The product covers general accounting, current accounts, bank and cash management, stock and warehouse management, sales and purchasing, CRM, service management, payroll and human resources, and reporting with customizable dashboards. Because it is built for the Turkish market, it supports e-transformation documents such as e-Fatura, e-Arşiv, e-İrsaliye and e-Defter, follows local accounting and tax rules, and works for multi-company and multi-branch structures. Mobile access lets managers approve and monitor from phones, and an API allows integration with e-commerce sites, marketplaces and other software. Pricing is quote-based according to modules and number of users.

DİA fits Turkish SMBs and mid-size companies that want a full ERP without maintaining local servers, as well as accounting offices serving clients across locations. Compared with traditional on-premise ERPs such as Logo and Mikro, its advantage is native cloud access and no installation; those vendors offer larger partner networks and cloud versions of their own. Paraşüt is simpler and cheaper for very small businesses that only need pre-accounting and invoicing.

Nilvera is a Turkish e-transformation provider based at Erciyes Teknopark in Kayseri. Nilvera Yazilim ve Bilisim Hizmetleri was founded in 2008, began building e-document products in 2012 and holds private integrator (ozel entegrator) approval from Turkey's Revenue Administration (GIB). It says it serves more than 50,000 businesses, with 78,000+ active users, 5,500+ accountant users and over 120,000 documents generated per day.

The catalog covers nearly every mandatory electronic document in Turkey: e-Fatura, e-Arsiv, e-Irsaliye, e-Defter, e-Saklama, e-SMM, e-MM, e-Adisyon, e-Sigorta and e-Gider Pusulasi, plus e-signature, financial seal (mali muhur), KEP and timestamp services. Documents are stored for 10 years, there is a dedicated portal for accountants managing many clients, and integrations link it to ERPs and e-commerce tools such as Odoo, Ideasoft, Orka and Jetstok. Pricing is credit-based (kontor) and sold mostly through partners; Nilvera does not publish a price list.

It fits Turkish SMEs, accountants and e-commerce sellers that need a low-cost integrator wired into their existing software. Parasut bundles e-invoicing into a full pre-accounting app, while Uyumsoft and Logo target larger ERP customers. Nilvera is not an accounting system itself, so you still need bookkeeping software.

Buying tip: businesses whose 2025 gross sales reached 3 million TL had to move to e-Fatura by 1 July 2026, and the same test repeats each year on prior-year sales. Partner channels such as Ideasoft sell discounted prepaid packs, and credits expire after 24 months, so buy for realistic volume.
