Take Control of Your Business Finances

Double-entry accounting for sole traders, landlords & the self-employed

DEB puts you in command of the general ledger — with full integration across the Sales and Purchase ledgers. End-of-period adjustments flow straight through to accurate financial statements. No duplicated effort, no fighting the software.

Why DEB is Different

Most accounting software treats record-keeping as an afterthought. DEB treats it as the foundation — because accurate books are what keep you compliant, informed, and in control.

True Double-Entry Control

Unrivalled control over the general ledger, fully integrated with the Sales and Purchase ledgers.

Timely, Accurate Statements

Make all end-of-period adjustments and produce financial statements in minutes, not hours.

Know Where You Stand

Know precisely what you owe, what you are owed, and your timescales for receipts and payments — with better estimates of pending Income Tax liability.

Built for Independence

Tools that serve you, not the other way around — designed for professionals who value their independence.

Real-time view of integrated ledgers: Bank, Sales, Purchases, VAT and receivables/accounts payable — all balanced automatically.

Stay Compliant with Making Tax Digital

Record relevant financial transaction data, smartly and accurately throughout the year, in the most consistent and organised way. Extract accurate revenue and expense account data for timely reporting to HMRC.

Avoid late filing penalties, unnecessary legal costs, and excessive professional fees.

For Bookkeepers & Independent Practitioners

DEB gives you the tools to provide top-quality financial accounting services — independently, on your terms — giving your clients total confidence in you, your practice and your dedication to maintaining the highest professional and ethical standards.
