Invoicing Software

One place to create, send and chase every invoice.

Invoicing software is the system a business uses to create invoices, send them, record what has been paid and follow up what hasn't. InvoiceSonic keeps clients, invoice numbers, due dates and payment status together, so small businesses stop rebuilding the same document in Word and stop guessing which invoices are outstanding. Start with an online invoice in the browser, carry on from the iPhone app, and let automatic payment reminders handle the follow-up.

Saved clients and invoice history · Payment reminders · iPhone app and web · No percentage of your payments

A billing system, not a bigger ledger — It looks after the money coming in. Keep payroll, bank reconciliation and tax returns in the accounting process your bookkeeper already uses, and hand over clean records at month-end.

What you get

Professional invoices in a few clicks

Pick a saved client, add line items from your price list, and totals, tax and the due date calculate before anything leaves the business. Your logo, business details and payment terms appear on every invoice without retyping.

Numbering and records kept in order

Every invoice takes the next number in the sequence and stays in one searchable history with its issue date, due date, amount and status — no duplicate numbers, no PDFs lost in a downloads folder.

Send it and see when it's opened

Email the invoice or share a secure link from the account. Open tracking shows when a client has viewed it, which removes the 'I never received it' delay.

Reminders that chase late payments

Late payments are the most common cash flow problem for small businesses. Reminders go out on a schedule once an invoice passes its due date, so follow-up happens even in a busy week.

Repeat billing on a schedule

Retainers, maintenance agreements and weekly work can run as recurring invoices, each prepared on schedule and ready to review and send.

Online payments your way

Add bank transfer, PayID, PayPal or your own payment link. With a card link from a provider such as Stripe, clients may pay by credit card, Apple Pay or Google Pay through that provider. InvoiceSonic shows the instructions and never takes a percentage.

On the job and at the desk

Create an invoice on a mobile device with the iPhone and iPad app, then review it on a laptop later — same account, same clients, same history.

How it works

  1. 1

    Check the limits

    Look at how many invoices, clients and reminders each plan allows before you move your billing onto it, and whether credit cards or other online payments add fees.

  2. 2

    Test a real invoice

    Create one with your usual line items, tax and payment details, open it on your phone and check what the client sees.

  3. 3

    Set up follow-up

    Turn on reminders and recurring invoices for regular clients, then upgrade only when the volume justifies it.

Invoicing software vs accounting software

Both can send an invoice, but they are built for different jobs.

Accounting software
Xero, MYOB and QuickBooks are built around a general ledger: bank feeds, reconciliation, payroll, BAS or tax reports and financial statements. Invoicing is one module inside a larger subscription.
A dedicated invoicing tool
Focuses on billing and receivables — quotes, invoices, reminders and knowing who owes what. It is quicker to set up and cheaper to run.
Using both
Many small business owners bill day to day in a focused tool and give their accountant clean invoice records for the ledger. InvoiceSonic is designed for that handoff.

Takeaway: If you need to get paid before you need a full set of books, start with invoicing and add a ledger later.

Frequently asked questions

What is invoicing software?

An app that creates, sends and tracks invoices. Compared with a template it stores clients, numbers invoices automatically, calculates tax and totals, and follows up overdue invoices.

Is invoicing software the same as accounting software?

No. It handles billing and payment follow-up; a ledger product adds reconciliation, payroll and tax reporting. Many small businesses use both.

Is there a free version?

Yes. Your first invoice needs no account, and the free plan saves up to three invoices a month with one tracked send and one reminder. See free invoicing software Australia for how free tiers compare.

Can clients pay by card?

InvoiceSonic does not process payments. Add bank transfer or PayID details, or a payment link from a provider such as Stripe or PayPal; that provider handles card payments and charges its own fees.

Is there a mobile app?

Yes, a native app for iPhone and iPad. On Android, use the web app in your browser.

What does Pro cost?

A$19 a month for unlimited invoices, recurring billing, automatic payment reminders, open tracking and custom branding, with a 7-day trial (card required).
