QuickBooks

QuickBooks is online accounting software from Intuit that has long been the standard for small and medium businesses in the US and the UK. It is built for sole traders, small companies, and their accountants who need income, expenses, and invoices in one place instead of scattered spreadsheets and paperwork. You work in it through a browser and a mobile app, so you can reach your numbers from anywhere.

It works by connecting QuickBooks to your business bank account and cards, from which it automatically pulls transactions. You then sort them into the right categories, match them to invoices, and the software continuously shows how the business is doing - its cash flow, profit, and where the money goes. It tracks the invoices you issue and alerts you when a client hasn't paid.
