About Us

A joint product of accountants and software engineers

An İzmir-based software company developing cloud ERP for SMEs and growing enterprises since 2009.

Düzlem was founded in 2009 at İzmir Technopark when an accounting software team joined forces with certified public accountants. The idea was simple: small and mid-sized businesses need the power of the ERPs that large companies use, but cannot bear their complexity and cost. Today more than 1,250 companies use Düzlem ERP in their daily work.

Our product philosophy

One database, one user experience, one version. Every module uses the same customer card, item card and chart of accounts; data is never entered twice. So a sales invoice reduces stock, generates the accounting entry, sends the e-invoice to GİB and updates the cash-flow report.

Why implementation consulting?

The success of ERP projects depends on process more than software. Our team brings industry-specific experience at every step, from chart-of-accounts design to warehouse layout, approval flows and permission matrix. Our setup fee has fixed scope; there are no surprise costs.
