what you should beware of when invoicing in uk

Keep an eye on late payments - in the UK, businesses are entitled to charge interest on late payments. The interest rate is set by the government and is currently 8% plus the Bank of England base rate. All invoices should be issued in pounds sterling (GBP) unless otherwise agreed with the customer.

Invoices should be issued promptly after the goods or services have been provided, or as otherwise agreed with the customer. It's highly important to take into consideration protecting personal data. Businesses should comply with the General Data Protection Regulation (GDPR) when handling and storing customer information, including names, addresses, and payment details.

Best business app I’ve ever used!!! I tried many others. Nothing compared with how easy it is to send estimates and receive digital signatures from customers. It tells you every time a customer just looks at/opens the estimate and 1 button tap to turn an estimate to an invoice keeping track of every document you create. Wonderful!!!!! A must for small business and estimating purposes!!!
