DİA vs LUCA

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.

LUCA is a Turkish accounting software family launched in 2005 by TÜRMOB, the union of Turkish certified public accountants (mali müşavir), through its training arm TESMER. TÜRMOB describes it as Turkey's first web-based central accounting system. Luca Net was added for businesses at the end of 2013. Its core job is to let accountants keep the books of all their client companies in one system and file Turkish tax returns and e-ledgers directly with the Revenue Administration (GİB).

The flagship Mali Müşavir Paketi (MMP) prepares VAT, withholding (muhtasar), provisional tax, BA/BS and income or corporate tax returns and sends them to GİB e-Beyanname in bulk, produces e-Defter files, runs payroll with SGK incentives, imports bank statements and calculates inflation accounting. For businesses, Luca Net KOBİ handles current accounts, stock, invoicing, e-Fatura and e-Arşiv, and posts entries straight into the accountant's LUCA ledger; Luca Net One is a lighter version and Luca Koza targets larger firms. Pricing is in Turkish lira with a one-time entry fee plus an annual fee.

LUCA fits independent accountants and the small businesses they serve, especially when both sides use it and data flows without exports. It is weaker on modern UX, mobile apps and open APIs. Paraşüt and Logo İşbaşı are friendlier for business owners doing their own pre-accounting, while Mikro suits companies that need a full desktop ERP.

Buying tip: newly licensed accountants can get the MMP entry support package with no entry fee, and the e-Defter license is a separate one-time ₺9,000 charge.
