Frequently Asked Questions

How are the opening and closing entries created in e-Ledger? What is the structure of e-Ledger?
Financial consultants create two types of documents, one for opening and one for closing. Opening and closing records are entered with these documents. The documents are printed into the ledger according to their recording dates. For the opening, records dated Jan 1 are added to the beginning of the ledger while closing records dated December 31 are added to the end of the ledger.
What is the difference between full integration and a special integrator?
Special Integrator (SI):
• Generates, submits and tracks electronic records according to the technical guidelines set out and published by RA.
• In e-Invoice and e-Archive, signs electronic records with its own financial seal without the need for the taxpayer's financial seal or using the HSM device with high-speed signing power.
• Undertakes for its systems to be accessible and functioning 24/7.
• In addition to the cost of IT system, server and database costs also belong to the special integrator.
• Follows updates in legislation or technical guidelines on behalf of the taxpayer, provides information and applies the updates in its system.
• Special integrators, which provide costing per invoice and storage services, store the electronic records for the committed period.
• Special integrators back up taxpayers’ data, thus preventing data loss in disaster situations.
• The systems offered by special integrators and ERP applications can exchange data automatically.
• Mükellef adına GİB’e e-Fatura, e-Defter başvurusunda bulunamaz.
• Special integrator cannot apply to RA for e-Invoice, e-Ledger on behalf of the taxpayer.
Full Integration:
• The taxpayer itself is required to manage the IT system and server management, data archiving costs, following updates in legislation and technical guidelines, and their implementation to the system.
What needs to be done when switching from the old e-Ledger system to the new Detaysoft e-Ledger system?
Regarding the switch from your old e-Ledger system and migrating your data to the new Detaysoft e-Ledger system, we request invoice envelope and application reply envelope UBL files. (This is important in terms of replying to the old commercial invoices received within the legal period as approved/rejected.) If it is not kept as an envelope file, we can also migrate the invoices to the new system via the signed invoice UBL file.
What are the requirements of the SAP system?
The e-Invoice/Archive package can run in SAP R/3 4.6C and higher versions.
What is the cost of storage, and how is it calculated?
The cost of storage is a cost that the special integrator service brings. In cases when Detaysoft server is used, the monthly storage cost is calculated by adding the incoming and outgoing quantities.
