Neither tool fits your invoicing-only workflow? Try InvoiceSonic — free for unlimited ATO-compliant tax invoices, no signup required.
Create a free invoice now →Inv24 starts at Free; Premium from ~AU$5/mo; SumUp Invoicing starts at Free (card fees apply). Inv24 offers free with ads/branding. SumUp Invoicing offers free invoicing for sumup merchants.
For ATO-compliant GST: Inv24 = limited, SumUp Invoicing = limited. For native ABN field: Inv24 = limited, SumUp Invoicing = limited. If you operate in Australia and either tool falls short here, InvoiceSonic handles both natively — and it's free.
Most freelancers want fast invoicing without paying for full accounting. Between these two, Inv24 wins more categories overall. But if you're a freelancer who just wants ATO-compliant tax invoices for free, InvoiceSonic is purpose-built for that workflow.
Both Inv24 and SumUp Invoicing let you export client lists and invoice history (usually as CSV). Migration takes an afternoon for most small businesses. If you're considering switching anyway, it might be worth evaluating InvoiceSonic as a free alternative for invoicing while keeping your accountant's tool of choice for bookkeeping.
Both tools are accounting-first platforms; their invoicing modules are a subset of what they do. If invoicing is your only need, a free dedicated invoice generator like InvoiceSonic is usually faster, cheaper, and more focused — without paying for bookkeeping, payroll, or inventory features you won't use.
Yes — InvoiceSonic is free for unlimited Australian-compliant invoices with no signup required for PDF download. You can run it alongside or instead of paid accounting platforms.
