Invoicing Software for Australian Businesses

BizFlare's invoicing is built around one idea: getting a correct, professional invoice out the door should take under a minute, and getting paid for it shouldn't take weeks of follow-up. Every invoice carries your branding, applies GST automatically, and shows your ABN exactly the way the ATO expects — so there's nothing to check or correct after the fact.

  • Automatic GST (inclusive or exclusive) with ABN display
  • Quotes that convert to invoices in one click

Checking a GST tax invoice created in BizFlare invoicing software

Behind the scenes, invoicing is connected to the rest of your business. Send an invoice and stock updates automatically. Send a recurring invoice and it goes out on schedule without you touching it. None of this needs an accounting background to set up.

ATO-Compliant Tax Invoices with GST and ABN

An Australian tax invoice has specific requirements — your ABN, a clear description of what's being sold, the GST amount, and the total. Get any of these wrong or missing and it can cause real problems for your customer's own tax reporting, not just yours. Our free Australian tax invoice template lists every field the ATO expects.

BizFlare handles this automatically. Every invoice displays your ABN, calculates GST at 10% on either a GST-inclusive or GST-exclusive basis depending on how you price your products, and breaks the GST component out clearly on the document your customer receives. Come BAS time, there's nothing to add up by hand — see it summarised in your reports.

GST inclusive vs GST exclusive pricing

If you price your products with GST already built into the number your customer sees, BizFlare calculates the GST that's included in that total. If you price before GST and add it on top, BizFlare does that instead. (Need to check a figure by hand? Use the free GST calculator.) You set this once per product, and every invoice follows it automatically from then on.

Quotes That Convert to Invoices in One Click

Send a professional quote, and once your customer accepts it, turn it into an invoice without re-entering a single line item. The pricing, the description, the GST — all of it carries across exactly as quoted, so there's no risk of the invoice not matching what was agreed. See how quotes and estimates work in BizFlare.

You can track whether a quote has been viewed, and follow up on outstanding quotes before they go cold.

Recurring Invoices for Retainers and Subscriptions

If you bill the same customer on a regular schedule — a monthly retainer, a service contract, a subscription — set it up once and BizFlare generates and sends the invoice automatically on that schedule from then on. GST is applied the same way it would be on a one-off invoice, and you can pause, edit or cancel a recurring schedule at any time. See how recurring invoice schedules work for the full details.

Credit and Debit Notes with Full Audit History

Refunds, corrections and adjustments happen. When they do, BizFlare keeps a complete record — every credit note and debit note is linked back to the original invoice, so there's a clear audit trail showing exactly what was changed, when, and why. This matters at tax time and matters just as much if a customer ever queries a past invoice.

Get Paid Faster with Payment Tracking

Record each payment against its invoice as it arrives — in full or in part — and the balance updates straight away. Customers can also see every invoice in their own customer portal. BizFlare tracks the status of every invoice automatically — paid, partially paid, or overdue — so you always know where you stand without chasing up manually.

The customer payment portal

On the Business plan and above, you can let customers check their own balance through a secure portal login — their full invoice history, what's paid and what's outstanding, with every invoice shown in your own template. It gives customers a reference point instead of hunting through email for an old invoice.

Invoicing Software Pricing

Invoicing is included on every BizFlare plan, starting at $16/mo AUD inc. GST (billed yearly) for the Starter plan. There are no separate charges to unlock GST calculation or recurring invoices — they're part of the base product. The customer payment portal is included from the Business plan. See the full pricing page for a complete breakdown by plan.
