E-Invoice Integration Operations Outsourcing in Türkiye

Last updated: November 11, 2026

Türkiye has one of the most comprehensive e-document regimes in the world: e-Invoice (e-Fatura), e-Archive Invoice, e-Waybill (e-İrsaliye) and e-Ledger (e-Defter) are mandatory for a large share of businesses, and every document has to flow correctly between your ERP, your e-commerce and marketplace systems, a licensed private integrator and the Revenue Administration (GİB). Setting up the integration is only the beginning. Day to day, someone has to watch the queues, fix rejected or stuck documents, answer acceptance and rejection responses, reconcile orders with invoices and keep archives audit-ready. With e-invoice integration operations outsourcing, 360 Soft runs that operational layer for you.

The service is especially relevant for international groups with a Turkish subsidiary, where finance teams abroad need reliable e-document operations in Türkiye without building local expertise from scratch.

E-Invoice Integration Operations Outsourcing

What e-invoice integration operations are, and who needs them

Integration operations are the daily monitoring, exception handling, reconciliation and change management that keep e-documents flowing after go-live. They sit between your business systems and the private integrator you have chosen. 360 Soft is not a GİB-licensed private integrator and does not provide tax advice; we operate the technical and process side and work alongside your integrator and your tax adviser.

Businesses that need it most

E-commerce and marketplace sellers issuing thousands of e-Archive invoices per day.
Manufacturers and distributors with high e-Waybill volumes and frequent returns.
Foreign-owned companies whose group ERP (SAP, Microsoft Dynamics, Oracle) must speak Turkish e-document formats.
Retail and franchise chains with many branches and POS integrations.
Companies changing ERP or private integrator, or migrating to a new e-document scenario.

Common problems

Problem	Consequence
Documents stuck in queues or rejected by the integrator	Invoices not delivered, customer disputes, late filing risk
Wrong invoice type (sale, return, withholding, exemption, special base)	Incorrect VAT treatment and corrections
Commercial invoice rejections not tracked	Revenue recognised on invoices the buyer has rejected
Orders, invoices and marketplace settlements not reconciled	Gaps between sales, invoicing and collections
e-Ledger berat uploads late or failing	Compliance risk at period end
Knowledge held by one person	Operations stop when that person is absent

Regulatory and technical framework

The following is general information. The scope of mandatory e-documents, transition dates and thresholds are set by Tax Procedure Law general communiqués and change over time; please confirm your obligations with your financial adviser. Local e-invoicing rules in other countries where your group operates apply separately.

Document	In brief	Operational points
e-Invoice (e-Fatura)	Invoice between registered e-Invoice users; basic and commercial scenarios	Check whether the buyer is registered, track acceptance and rejection in commercial scenario, correct invoice type
e-Archive Invoice	Invoice to buyers not registered for e-Invoice, including consumers	Delivery by email or portal, daily reporting, cancellations
e-Waybill (e-İrsaliye)	Electronic dispatch note for goods movement	Issue before shipment, receipt responses, matching to invoices
e-Ledger (e-Defter)	Electronic accounting books with monthly berat	Timely generation, signing and upload of berats
e-SMM and e-Producer Receipt	Freelance and agricultural producer receipts	Included where in scope

The private integrator concept

Most companies send and receive e-documents through a GİB-licensed private integrator (özel entegratör). The integrator provides the transmission and storage infrastructure; your company remains responsible for the content of the documents. Our operations team manages the connection between your systems and the integrator, monitors statuses and supports integrator selection or migration from a neutral technical position.

Retention and proof

E-documents must be retained for the statutory period and be producible on request. We check that archives are complete, that statuses are consistent between ERP and integrator, and that evidence for rejections, cancellations and returns is kept.

Service scope

Queue and status monitoring: outgoing and incoming documents, integrator responses and error codes, with alerts for stuck items.
Exception handling: analysing rejected, failed or duplicated documents and correcting master data or mappings with your team.
Commercial invoice responses: tracking acceptance and rejection deadlines and informing finance.
Reconciliation: orders, waybills, invoices, marketplace settlements and ERP postings.
e-Ledger support: monitoring berat generation, signing and upload status.
Change management: new document types, scenario changes, format updates and testing.
Integrator migration support: requirements, testing, cut-over and hypercare.
Reporting: daily and monthly volume, error and backlog reports.

Risks and mitigations

Responsibility confusion: a RACI that separates your tax responsibility, the integrator’s infrastructure and our operations.
Regulatory changes: monitoring announcements with your adviser and planning format updates early.
Access risks: least-privilege accounts; financial seals and e-signatures stay under your control.
Knowledge concentration: documented runbooks and team coverage.

Security, GDPR, KVKK, confidentiality and intellectual property

Invoices contain personal and commercial data. Team members sign NDAs, use named accounts with logging, and process data only on your instructions. Your financial seal (mali mühür) and e-signature certificates remain yours. Scripts, mappings and documentation created for you are your property.

Legal note on the contract model

International clients work with us under a B2B service agreement with statement of work and SLAs, IP assignment, NDA and, where personal data is processed, a GDPR data processing agreement with Standard Contractual Clauses (UK IDTA for UK clients); KVKK applies in Türkiye. Tax responsibility stays with your company. This is general information, not legal or tax advice.

Frequently asked questions

What is the difference between integration operations and integration set-up?

Set-up connects your systems to the integrator once. Operations keep documents flowing every day: monitoring, exceptions, responses, reconciliation and changes.

Is 360 Soft a private integrator?

No. 360 Soft is not a GİB-licensed private integrator. We manage the operational layer between your systems and the integrator you choose, and support integrator selection or migration neutrally.

Which e-document types do you cover?

e-Invoice, e-Archive Invoice, e-Waybill and e-Ledger, plus e-SMM and e-Producer Receipt where they are in scope.

Which ERP systems and integrators do you work with?

SAP, Microsoft Dynamics, Logo, Netsis, Mikro and custom ERPs, and integrators that offer web services or APIs. Exact fit is confirmed during discovery.

Do you decide whether we fall under the e-Invoice obligation?

No. Obligations are a tax matter for your financial adviser. We operate the technical and process side once scope is confirmed.

How are rejections of commercial invoices handled?

We track response deadlines and rejections, inform your finance team and support corrections or replacement documents according to your procedures.

Do you reconcile marketplace orders with invoices?

Yes. We match orders, invoices, returns, settlements and ERP postings and report gaps.

Do you upload e-Ledger berats?

We monitor generation and upload status and support your team; signing and responsibility for the books stay with your company and adviser.

Does our financial seal or e-signature stay with us?

Yes. Seals and certificates remain under your control and are never transferred to us.

Do you support a change of integrator?

Yes. We help define requirements, test, plan cut-over and stabilise operations after the switch.

How is pricing determined?

By document volume and types, number of connected systems, coverage hours, initial backlog and development needs.

Which contract model is used?

A B2B service agreement with SLAs, IP assignment, NDA and, where needed, a GDPR DPA with SCCs or UK IDTA; KVKK applies in Türkiye.
