## E-invoicing

| Status | In force Live with taxpayer, activity and document-specific scope |
|---|---|
| Model | GİB e-Fatura and e-Arşiv Fatura with separate e-ledger and dispatch documents |
| Evidence | Official e-document guidance and April 2026 e-Arşiv material · checked 2026-10-17 · [[1]](https://cdn.gib.gov.tr/api/gibportal-file/file/getFileResources?objectKey=arsiv%2Fyardim-kaynaklar%2Finfografikler%2Fpdfs%2Fe_arsiv_fatura.pdf) [[2]](https://gib.gov.tr/mevzuat/kanun/434/teblig/8161) [[3]](https://gib.gov.tr/vergi-konulari/2_isletme_ve_girisimci/13_mukelleflerin_ise_baslama_ve_isi_birakma_odevleri/13) |

### Scope and timing

Turkey's Revenue Administration, GİB, distinguishes **e-Fatura** between registered participants from **e-Arşiv Fatura** for the relevant supplies to recipients outside that registration, including consumers. Obligations depend on taxpayer/activity and transaction rules; the fact that a transaction is B2B does not by itself identify which document route applies. [GİB: e-document and commencement guidance](https://gib.gov.tr/vergi-konulari/2_isletme_ve_girisimci/13_mukelleflerin_ise_baslama_ve_isi_birakma_odevleri/13).

Current **April 2026** e-Arşiv guidance must be compared with older leaflets before quoting thresholds. Its examples include a 2026 amount test for a described population; this research does not publish a universal zero-threshold rule from an older future-date statement. B2G recipient arrangements, exports and special sectors need their own applicable provisions. [GİB: current e-Arşiv infographic](https://cdn.gib.gov.tr/api/gibportal-file/file/getFileResources?objectKey=arsiv%2Fyardim-kaynaklar%2Finfografikler%2Fpdfs%2Fe_arsiv_fatura.pdf).

### Invoice lifecycle and data

Confirm issuer enrollment, recipient enrollment, permitted portal/integration arrangement and the current document schema. Preserve party identifiers, invoice identity, relevant scenario, original content and returned outcomes. Determine the permitted rejection/cancellation/corrective document route before changing an already issued invoice.

e-İrsaliye dispatch documents and e-Defter electronic ledgers are separate obligations. Producing an e-invoice does not establish goods-movement or electronic-bookkeeping completion. GİB's e-Defter communiqué provides an independent legal framework and current categories. [GİB: e-Defter communiqué](https://gib.gov.tr/mevzuat/kanun/434/teblig/8161).

### ERP implications

Maintain effective-dated taxpayer and recipient statuses and map e-Fatura/e-Arşiv selection explicitly. Identify the fields needed for export or sector-specific treatment rather than placing all invoices into one default scenario. Test the actual deployed integrator and release; do not infer native support from a general country-localization label.

Reconcile commercial documents, tax-platform results, dispatch records and ledger outputs by their own purposes. A retry must not create another sale or overwrite the issued original. Confirm retention and readable retrieval, including the responsibilities retained by the taxpayer when an integrator stores documents.

### Sources and evidence limits

Checked **17 October 2026** through indexed official guidance. Complete consolidated threshold amendments, public-sector special cases, production schemas, correction deadlines and retention details were not exhaustively reviewed. No universal 2026 threshold or one deadline covering every taxpayer is asserted.

**Limitations:** Current April 2026 guidance used; complete consolidated threshold changes and special cases not audited. No universal 2026 threshold asserted from older leaflets.

## Localisation via local partner

| ERP | Flag | Note | Source |
|---|---|---|---|
| Business Central | local partner | No Microsoft localization; Microsoft documents that partners localize Business Central here with apps on Microsoft Marketplace (W1 base). | verified [[1]](https://learn.microsoft.com/en-us/dynamics365/business-central/dev-itpro/compliance/apptest-countries-and-translations) checked 2026-10-16 |
| NetSuite | limited native / partner | Oracle lists no country-specific NetSuite help topics; localisation usually through partner SuiteApps or add-ons (region-specific SuiteApps may still apply). | verified [[1]](https://docs.oracle.com/en/cloud/saas/netsuite/ns-online-help/book_4198429264.html) checked 2026-10-16 |
| SAP S/4HANA Cloud | local partner / add-on | No SAP-delivered country version listed; usually localised through a partner add-on. (SAP list of S/4HANA Cloud public edition country versions, v02_2024.) | verified [[1]](https://www.sap.com/documents/sap-s4hana-cloud-available-country-versions-1044293) checked 2026-10-16 |

Flags are derived from vendor country lists only (Microsoft Business Central availability table, Odoo fiscal localizations, Oracle NetSuite country help, SAP S/4HANA Cloud country versions). SAP S/4HANA Cloud flags use the SAP country-version list (v02_2024). Sage Intacct, Workday, Unit4 and IFS are not flagged yet.
