Why Do Businesses Choose e-Defter PRO?
With the features below, e-Defter PRO makes a significant difference by simplifying businesses' e-ledger processes.
Is e-Defter PRO compatible with accounting software?
Yes, e-Defter PRO works with 100% compatibility with Zirve, GMS.NET, Luca, Logo and all accounting software on the market. You can import data within minutes without any format conversion.
What are the certificate submission deadlines?
For monthly uploads, the deadline is the last day of the third month following the relevant period. For quarterly uploads, it is the 10th (or 14th for corporate taxpayers) of the month following the tax return deadline. If the deadline falls on a holiday, it extends to the next business day.
Is e-Defter PRO compliant with GİB standards?
Yes, e-Defter PRO is an officially compliant e-Ledger software that fully meets all technical standards and Schematron rules set by GİB. Certificate creation, signing and submission processes are automatically executed according to regulations.
What changed in e-Ledger in 2025?
Starting from January 2025, not only certificates but also the Journal XML file must be submitted to GİB. Only certificate submission continues for the General Ledger and Inventory Ledger. e-Defter PRO supports journal, general and inventory ledgers with full infrastructure for this requirement.
Can I use it without a Financial Seal or e-Signature?
Yes. You can submit through e-Defter PRO with a power of attorney compliant with GİB standards, even without a financial seal or e-Signature. Our team provides detailed guidance on the power of attorney process.
How long must e-Ledgers and certificates be retained?
Under the Tax Procedure Law, e-Ledger files, taxpayer certificates and GİB-approved certificates must be retained for the legal period (generally 10 years) and presented upon request. e-Defter PRO archives all your files securely in the cloud.
Can I modify records after submitting certificates?
No. Once the certificate for a given month is submitted to GİB, no changes can be made to the accounting records for that period. This is why careful pre-submission verification is crucial. e-Defter PRO's validation tools simplify this process.
What happens if I miss the submission deadline?
E-Ledger certificates that are not created, signed, or uploaded to GİB within the legal deadline are subject to special irregularity penalties under the Tax Procedure Law. e-Defter PRO's automatic reminder system reduces your risk of missing deadlines to zero.
Who is required to keep e-Ledgers?
Taxpayers subject to e-Invoice obligations, all taxpayers keeping balance sheet-based books, and taxpayers in specific sectors designated by GİB (energy, fuel, etc.) are required to keep e-Ledgers.
Can I get support during use?
Absolutely. e-Defter PRO offers 24/7 expert technical support via email, with phone support available during business hours. We also provide comprehensive online training videos and step-by-step user guides to support you throughout every process.
