Hang Invoice

Run your invoicing workflow from your Android device—even when you are offline.

Hang Invoice helps freelancers and small businesses create invoices, estimates and quotes, keep customer details organized, and produce clear business documents without creating an account. Your core business records stay on your device, with cloud backup and device transfer disabled.

CREATE PROFESSIONAL DOCUMENTS

• Build invoices, estimates and quotes with automatic numbering

• Add line items, quantities, prices, percentage discounts and taxes

• Include a reference or PO number, notes and terms

• Add your business contact details and logo

• Choose from Minimal, Classic and Bold document templates

• Generate multi-page PDFs, then share, save or print them

MOVE FROM QUOTE TO INVOICE

Create an estimate or quote, mark it as sent, record whether it was accepted or declined, and keep track of expired documents. When a customer accepts, convert the document into a new invoice without entering the customer, items, discounts, taxes, notes or terms again.

TRACK INVOICES AND PAYMENTS

See draft, unpaid, partial, paid, overdue and cancelled invoice statuses. Record cash, card, bank transfer, local bank or other payments manually, and view the remaining balance. Home summaries show open invoices, overdue invoices and outstanding amounts at a glance.

KEEP CUSTOMER DETAILS TOGETHER

Create searchable customer profiles with company, phone, email, address, tax ID and notes. Open a customer to review invoice history, invoiced totals, recorded payments and outstanding balances.

WORK THE WAY YOUR BUSINESS WORKS

• Set your business currency and tax rate

• Configure estimate and quote prefixes and default validity

• Reuse recent line items

• Search and filter documents by customer, number, type or status

• Use light, dark or system appearance

• Use the app in English, Khmer, French or Spanish

DESIGNED FOR ON-DEVICE WORK

Core document creation, numbering, calculations, customer management and PDF generation work without an account or a server connection. Business, customer, document, payment and logo data is stored locally on your device.
