Accounting software is a tool that records your business's money and turns it into invoices, VAT returns and reports, automatically. This guide explains what it does, who needs it, and why it has largely replaced spreadsheets.

Accounting software is a program that keeps track of the money coming into and going out of a business, and turns those records into useful things: invoices, a VAT return, a profit and loss statement, a view of who owes you money. Instead of typing figures into a spreadsheet or keeping paper receipts, you record transactions once and the software does the rest.
Good modern software is built so that you don't need to understand debits, credits or double-entry bookkeeping, it handles the accounting mechanics behind the scenes while you work in plain English.
The core jobs most small businesses use it for are: creating and sending invoices, recording expenses, connecting to your bank so transactions import automatically, reconciling those transactions against your records, calculating VAT, and producing reports like profit and loss and a cash-flow view. It also keeps the digital records required under Making Tax Digital.
Sole traders, freelancers, creators, e-commerce sellers, small companies and bookkeepers all use it. If you invoice customers, claim expenses, are (or will be) VAT registered, or simply want to know how your business is doing, accounting software makes that far easier than doing it by hand.
Spreadsheets work at the very start, but they don't connect to your bank, don't stop you making errors, and, crucially, don't meet Making Tax Digital's requirement to keep digital records and file through software. Accounting software automates the repetitive parts and keeps you compliant as the rules tighten.
No. Beginner-friendly software like Berified lets you describe transactions in plain English and does the bookkeeping for you, no training required.
Bookkeeping is the activity of recording transactions; accounting software is the tool that does most of that recording and turns it into reports.
No. It reduces the day-to-day work and gives your accountant clean records, which can lower their fees, but it isn't a substitute for professional advice.
