Most invoicing apps were not designed for a plumber quoting a boiler replacement from the van. Some are UK-only, which matters if you ever cross the Irish Sea. Some have no knowledge of trade VAT rates. Here is an honest assessment of what actually works.

Standard rate is 20% on most plumbing work. The 5% reduced rate applies to certain domestic energy-saving installations - heat pump fitouts, qualifying insulation work. Generic apps make you enter the rate manually. Trade-specific apps pre-set the right rate for the job type.
A plumber quoting a bathroom installation on site needs to produce a professional, itemised quote fast - before the customer calls someone else. If your app takes 20 minutes to fill in a form, you are losing jobs. If it generates a complete quote from a plain English description in 30 seconds, you are winning them.
A boiler replacement or bathroom fit can run to thousands of pounds. Late payment on a job like that damages your cash flow badly. An app that helps you send a professional, polite but firm payment reminder - without it feeling personal - makes a real difference to how quickly you get paid.
