GST invoice PDFs

GST-aware invoice PDF app for iPhone

InvBAS helps Australian small businesses preview and share invoice PDFs with business details, customer details, payment details, line items, and GST-aware wording.

Professional invoice PDFs from iPhone

InvBAS turns the details already entered in the app into a simple invoice PDF. The PDF can include the business profile, customer information, invoice number, line items, totals, due date, and payment details.

The workflow is designed for a small operator who wants to create and send a readable invoice from iPhone without setting up a full accounting platform.

GST registration setting controls the wording

InvBAS uses the user's GST registration setting to guide invoice wording. If the business is marked as GST registered, the app can present GST-related totals from the entered information. If the business is not marked as GST registered, the invoice can show that no GST has been charged.

This makes the invoice PDF clearer for customers because the wording follows the business setting in the app.

Details the PDF can show

Business name and details from the user profile.
Customer details saved in the app.
Invoice number, dates, paid status, and line items.
Totals and GST-related wording from the user's settings and entries.
Payment details such as PayID or bank details from the profile.

Local records after sharing

The invoice PDF is part of a wider local record workflow. Current InvBAS records are stored on the user's device unless the user exports, backs up, emails, or shares them through system services.

Not tax or GST advice

InvBAS does not decide whether a business should register for GST, does not lodge BAS, does not submit tax returns, and does not provide tax, BAS, GST, accounting, legal, financial, business, or superannuation advice. Users remain responsible for checking their own obligations.

Common questions

Can InvBAS show GST details on invoice PDFs?

InvBAS uses the user's GST registration setting and entered invoice amounts to show GST-related invoice wording and totals in the generated PDF.

What happens if the business is not registered for GST?

When a business is not marked as GST registered, InvBAS can show wording that the business is not registered for GST and no GST has been charged.

Does InvBAS send invoices for me?

InvBAS lets users preview and share invoice PDFs through iOS. It does not operate as an email service, payment processor, or accounting platform.
