3S Invoice is invoicing for small businesses, without the accounting. Issue an invoice in a few taps, see who owes you money, remind them politely, and know whether you are making a profit. It works offline, needs no account, and keeps your data on your phone. In English, Arabic and French, with Arabic fully right to left.

FREE, WITH NO LIMIT ON INVOICES OR CUSTOMERS
- Invoices: draft, issue, edit, duplicate and cancel. A number is given when you issue, and never reused.
- Payments: record a full or partial payment in a few taps, post-dated cheques included. Paid, partially paid and overdue are worked out for you.
- Reminders: send a friendly, firm or final reminder by WhatsApp, SMS or email, in your customer's language.
- Customers: see what each customer owes you, with a statement of their invoices and payments.
- PDF: share invoices and statements as PDF, or print them on A4 or Letter through your phone's printing.
- Home: what you are owed, what is overdue, and what you invoiced and collected this month.
- Tax: add VAT to your lines, or turn tax off.
- Backups: back up whenever you want, save the file on your phone or send it anywhere (Drive, email, WhatsApp), and restore it on this phone or a new one.

PRO
- Quotations: send a quote, then turn it into an invoice.
- Expenses: record what you spend, by category.
- Projects: see what each project earned, what it cost, and what is still to collect.
- Reports: profit and loss, sales, expenses, projects, and money owed by age, on what you invoiced or what you collected, each with a PDF.
- Receipt printing (Android): print invoices, quotations and statements on a 58 mm or 80 mm Bluetooth receipt printer paired with your phone.

Pro is sold two ways, and both unlock the same features: Lifetime, one payment with no renewals, or Yearly, a subscription you can cancel any time. The app shows the prices in your currency. If Pro ends, nothing is taken from you: your quotations, expenses and projects stay readable, and quotation PDFs can still be shared and printed.

OFFLINE AND PRIVATE
- No account, no sign-up.
- Your business data stays on your phone. We don't collect it, and the app has no ads and no analytics.
- The app goes online only through Google Play, for purchases and prices.

MADE FOR ARABIC, ENGLISH AND FRENCH
The whole app and every PDF read correctly in Arabic, right to left, even with Arabic and English names on the same invoice. Arabic dates can use the Levantine month names (آب، أيلول), the standard ones (أغسطس، سبتمبر) or numbers. One currency per business, three-decimal currencies such as the Kuwaiti and Jordanian dinar included.

E-INVOICING
In Saudi Arabia, Egypt, Jordan and the UAE, some businesses must issue e-invoices through the government's system. A PDF from 3S Invoice is not an e-invoice, so check whether this applies to you.
