    Frequently Asked Questions

    Why switch from Wave to Invoicemonk in the UK?

    Wave lacks UK-specific compliance features: no MTD VAT support, no CIS reverse charge invoicing, no automatic 20% VAT for GBP, and no VAT number fields. Invoicemonk includes all of these on its Pro plan ($15/month), plus multi-currency invoicing for UK businesses billing internationally.

    Is Wave free in the UK?

    Wave's invoicing is free, but payment processing charges fees (2.9% + 20p for cards). Wave also lacks UK tax compliance features, meaning you'd need additional software for MTD compliance — adding hidden costs.

    Can I import my Wave data into Invoicemonk?

    Yes. Export your client list and invoice history from Wave as CSV, then import into Invoicemonk. Your invoice numbering can continue from where Wave left off.
