Sole trader invoice app
Sole trader invoice app for Australia
InvBAS helps Australian sole traders create invoice PDFs, save customers, track paid and unpaid invoices, and keep invoice records locally on iPhone.
Built for small operator invoicing
A sole trader often needs a faster invoice workflow than a full accounting system. InvBAS keeps the path simple: add the customer, enter the work or item, preview the invoice PDF, then share it from iOS.
The app is useful for repeat customers, small jobs, contract work, mobile services, and simple service invoices where the main requirement is a clear PDF and a record that can be reviewed later.
What the invoice record can include
- Customer name and contact details.
- Invoice number, issue date, due date, and paid status.
- Line items, quantities, unit prices, and totals.
- Business details and payment details from your profile.
- GST-aware wording based on your app setting.
Local-first record keeping
Current InvBAS records stay on your device unless you export, back up, email, or share them through system services. That makes the app a practical fit for users who want invoice records on iPhone without creating another cloud login.
Useful next to BAS preparation
Invoice records can help you review sales and paid status before preparing your own BAS or talking with an accountant. InvBAS does not lodge BAS, submit tax returns, connect to the Australian Taxation Office, or provide tax, BAS, accounting, legal, financial, or superannuation advice.
