e-INVOICE & SALES · SALES

Issue the sale, the invoice comes GİB-ready

Issue the invoice by hand or from an accepted proforma; VAT splits included or excluded and on a foreign currency the live central-bank rate drops onto the line. The system checks the customer's taxpayer status and builds the document as e-Invoice or e-Archive — but it doesn't send to GİB until you approve. On approval the ETTN forms, a credit is used, and the payment link goes to the customer.

THE MODULE'S UNITS

Five units, one file: from sale to GİB

The e-invoice module is more than an issuing screen — from the invoice file to VAT and currency, from the GİB e-document engine to credit management, from A4 output to collection, an end-to-end accounting desk. Each of the five units closes one job.

Invoice File

Every invoice from draft to collection in one list — status, amount and customer at a glance.

Open the File

VAT & Currency

VAT included or excluded, multiple rates, USD/EUR/GBP at the live central-bank rate.

GİB e-Invoice & e-Archive

The system checks the taxpayer and prepares the document; you approve, it goes to GİB.

e-Invoice Credits

Each send is one credit; balance, run-out estimate — the platform tops it up.

See Credits

A4 & Collection

Brand-coloured A4 print plus a payment link; you issue the invoice and start collection.

01 · INVOICE ENGINE

Issue the sale, let the invoice pull itself together

By hand, from an accepted proforma or a sales channel — however the invoice starts, the same discipline: VAT splits, the rate is applied, the taxpayer is checked, the document comes GİB-ready; the approval stays with you.

BY HAND OR FROM A PROFORMA

Issue an Invoice

Customer, lines, VAT; or turn an accepted proforma into an invoice in one click — the products drop in themselves.

VAT & RATE AUTOMATIC

No Maths on You

VAT splits included or excluded, and on a foreign currency the live central-bank rate drops onto the line — the base never slips.

READY FOR GİB

e-Document

e-Invoice or e-Archive — the system checks the taxpayer; you approve, and only then does it go to GİB.

INVOICE LIFECYCLE

The invoice's stop-by-stop flow

The sale is issued, VAT and rate split, the taxpayer is checked, the ETTN forms, it goes to GİB, collection starts — every stop posts to the file. The document goes with your approval, the credit is used on send.

Explore Invoicing
The system prepares, you approve. Every document to GİB goes with your approval — no automatic sending. The taxpayer check, e-Invoice/e-Archive choice and ETTN generation happen by themselves; the "Send" button is yours.

02 · GİB & e-DOCUMENT

You don't carry the document to GİB: the system prepares, you approve

The system checks the taxpayer and builds the document as e-Invoice or e-Archive; it won't reach GİB until you hit "Send". For a real person the first and last name go separately, for a legal entity the title and VKN — all to the rule.

e-Invoice e-Archive ETTN Name Split

Taxpayer Auto-Check

Is the customer an e-invoice taxpayer? The system checks by VKN/TCKN and builds the document as e-Invoice or e-Archive.

  • Check by VKN/TCKN
  • e-Invoice / e-Archive automatic
  • The right document type is built
See the Engine

Draft → Approve → Send

The invoice is a draft first; it doesn't reach GİB until you approve. The ETTN forms on send, a credit is used.

  • Draft first, then send
  • ETTN forms on send
  • No GİB without your approval
See the Flow

Real-Person Split

For an 11-digit TCKN the first and last name go separately; for a legal entity the title and VKN.

  • First + last name split (TCKN)
  • Title + VKN for entities
  • Built to the document rule
See the Split
No automatic sending — the final word is yours. The system checks the taxpayer, prepares the document, generates the ETTN; but every invoice to GİB goes with your approval. Save a draft first if you like, review, then send.
03 · A4 OUTPUT STUDIO

The invoice print is yours too: brand-⁠coloured A4, logo, ready template

The invoice output isn't a blank sheet: A4 in your brand colour, your logo, a status badge — one-click print or PDF. Pick from ready GİB templates (standard, signed, single-page); the output should look like your company too.

Brand & logo Modern A4 Ready template One-click print
04 · COLLECTION CHANNEL

The invoice is issued: the payment link is with the customer, let collection start

The moment the invoice is issued, a collection link goes to the customer — by SMS and e-mail. The customer pays from the link; the invoice posts to the account balance, and the payment status — draft, sent, paid — is watched live.

Payment link SMS + e-mail Posts to the account balance Payment status tracked
05 · CREDITS & INBOUND

The invoice file runs itself: credits, inbound document, account — all on record

Each send is a credit; the balance and a run-out estimate sit on the panel. Approve or reject an inbound supplier invoice; on approval the account balance updates — the file runs itself.

Credit Management

Each e-document send is a credit; the balance and a run-out estimate sit on the panel, the platform tops it up.

  • A credit per send
  • Balance + run-out estimate
  • Tracked from the panel
See Credits

Inbound Invoice Approval

A supplier document arrives; approve or reject. On approval the supplier account balance updates.

  • Inbound document box
  • Approve / reject
  • Account balance updates

Account & Status Tracking

The invoice posts to the account balance; draft, sent, paid — the status is watched live.
