# E-Transformation: e-Invoice, e-Archive, e-Ledger

Page: https://atabekmusavirlik.com/en/hizmetler/e-donusum

We plan your e-invoice, e-archive and e-ledger transitions to your obligation scope, from application to daily use.

E-transformation replaces paper invoices and books with electronic documents. For taxpayers over certain turnover and sector thresholds, e-invoice, e-archive and e-ledger are mandatory; others can switch voluntarily to speed up their processes. Determining your obligation scope correctly is the first step to avoiding penalties.

We choose the model that fits you among portal, integrator or private-integration options and handle application, setup and initial training. Your invoices are issued error-free and your e-ledger certifications are uploaded on time.

**What's included**

- Determining e-invoice / e-archive obligation scope
- GİB portal / integrator application steps
- e-ledger creation and certification tracking
- Setting up invoicing and archiving processes
- User training and ongoing support

**Frequently asked questions**

- **Q: Do I have to switch to e-invoice?**
  A: e-invoice/e-archive is mandatory for taxpayers above a certain turnover threshold or in certain sectors. Below the thresholds, the switch is optional. Let's clarify your current scope together.
- **Q: What is the difference between e-archive and e-invoice?**
  A: An e-invoice is issued within the system between two e-invoice taxpayers. An e-archive invoice is issued electronically to recipients who are not e-invoice taxpayers (e.g. end consumers). Which applies depends on the recipient.
