Neither tool fits your invoicing-only workflow? Try InvoiceSonic — free for unlimited ATO-compliant tax invoices, no signup required.
Create a free invoice now →Billdu starts at Free; Premium from ~AU$7/mo; Clear Books starts at From ~AU$15/mo. Billdu offers free with limits; premium unlimited. Clear Books offers 30-day trial.
For ATO-compliant GST: Billdu = limited, Clear Books = limited. For native ABN field: Billdu = limited, Clear Books = 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, Billdu 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 Billdu and Clear Books 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.
