# Invoices and estimates that leave with you.

WinnerInvoice is a mobile invoicing app from ICI Tech Teknoloji A.Ş. It is built for the minutes after a job: draft on a phone, preview a branded PDF, and send it before you drive away.

## Field work is fast. Paperwork should not wait for the office.

Spreadsheets, paper notes and desktop accounting suites slow people down on site. WinnerInvoice is built around one action: create a professional invoice or estimate and put it in the customer’s hands from the job—even when the signal is weak.

## Built for the mobile moment, not the back office.

### Customer-facing PDFs

Invoices and estimates with logo and brand colour, so the document looks like your business rather than a generic template.

### Offline drafts

Keep working on sites with poor coverage. Preview locally, then share when the connection returns.

### Share where work already happens

Send by WhatsApp or email, or export a PDF. Reuse clients, line items and drafts so repeat jobs do not start from a blank form.

## Trades, repairs and small teams who bill from a van, not a desk.

If you quote on site and need a document the customer can trust, WinnerInvoice is meant for that loop—not for payroll or VAT returns.

- Repair technicians who invoice before leaving the property
- Plumbers who send an estimate first, then convert it after approval
- Electricians who need a clean PDF for residential and commercial jobs
- Freelancers who want client-ready invoices without a full accounting suite
- Small field crews who reuse customers and services across jobs

## Create, preview, share, track, reuse.

1. **Create:** Add items, quantities and customer details—minimum fields first.
2. **Preview:** Check totals, layout and branding before anything leaves your phone.
3. **Share:** Send by WhatsApp, email or PDF export.
4. **Track:** See open, paid and draft documents without turning the app into a ledger.
5. **Repeat:** Reuse saved clients and services on the next job.

## Clear about what WinnerInvoice is—and is not.

### It is

- A mobile invoicing and estimate app
- A way to draft branded PDFs offline
- Quote-to-invoice conversion for approved jobs
- WhatsApp, email and PDF sharing
- Multilingual and multi-currency documents for mixed client lists

### It is not

- Accounting or bookkeeping software
- Tax filing or payroll
- Legal e-invoicing or government invoice rails
- Financial, legal or tax advice
- A replacement for your accountant

You remain responsible for invoicing rules in your market. Confirm local compliance with a qualified adviser.
