Side-by-side comparison

The key difference
Invoice Simple will create an invoice. But it knows nothing about how tradesmen work, what VAT rates apply, or how a plumber charges for labour versus materials.
PayReady
Describe the job the way you would explain it to a client. PayReady AI builds a professional quote in 30 seconds - with the correct VAT for your trade, your rates, your logo, your currency. Send it via WhatsApp in one tap. PayReady AI writes the payment chaser when a client goes quiet.
Invoice Simple
Invoice Simple lets you fill in an invoice form on your phone. There is no AI quoting, no trade-specific VAT, no WhatsApp send, no payment reminder system, and no understanding of how tradesmen in Ireland or the UK actually work. It is built for anyone who needs to send an invoice - not for tradesmen specifically.

The VAT problem
In Ireland, a plumber charges 13.5% VAT on labour and installation work, and 23% VAT on materials supplied separately. Getting this wrong on an invoice can cause problems with Revenue and leave you short.
PayReady knows this distinction. Set your trade type once during setup and the correct VAT rate is applied automatically on every quote and invoice. Invoice Simple requires you to manually enter a VAT rate on every single invoice.
