The World's Simplest Accounting Software

basic accounting software cash book software simple accounting software

LedgerLite is an accounting system for any organization that needs a general ledger or cashbook.  Because it is incredibly easy to download and use, it will also appeal to students of double-entry bookkeeping.

LedgerLite provides unparalleled flexibility.  All account balances are calculated dynamically so that the standard accounting reports can be created for any arbitrary date or period without the need for a period close or roll-over.

Simply download the LedgerLite EXE file to your computer's hard drive or USB stick and run.  The database gets created automatically.  You can keep both program and data on a USB flash drive making it easy to backup or share with your accountant.  To access simply plug into any USB port on any Windows computer and run.  It doesn't get much easier than that!

Ledger (the precursor to LedgerLite) received more than half a million downloads when it was first made available in December 2004 without A SINGLE BUG REPORT!  For more information about LedgerLite please see the LedgerLite Facebook page or go directly to the LedgerLite website.

Important Note For New Users

Other popular accounting systems try to conceal the true nature of accounting but not ours.  Although LedgerLite makes it easy to work like an accountant you still need to understand double-entry bookkeeping and the function of a general ledger.  However once you've grasped these basic principles (it's not that hard) you'll find LedgerLite simpler, easier, better, faster, cheaper, more reliable, more flexible, more stable and more secure than any other accounting system.  You'll also come to appreciate the Divinely-inspired insight of a fifteenth century Italian monk who saw with clarity how God meant it to work some 500 years ago!

How Is LedgerLite Different From Other Accounting Systems?

LedgerLite keeps you in control of your data (unlike SaaS that keeps it somewhere in the cloud.)

LedgerLite is easy to use by anyone new to double-entry bookkeeping.

LedgerLite is upwardly scalable to enterprise-level when your business grows.

LedgerLite is traditional software that runs on any Windows computer.

LedgerLite requires no installation and can be run directly from a USB stick.

Customized Business Software - Without Limits!

LedgerLite is based on a revolutionary architecture that allows for an unlimited number of users via TCP/IP.  Using our uniquely designed application Framework a competent programmer can build a secure reliable customized enterprise-level system that runs over the Internet faster and more cheaply than anyone ever thought possible!

SANITY CHECK - Why would anyone in their right mind waste hundreds of thousands or even millions of dollars on a computer system that's built on a kludge and riddled with bugs and security holes when by using our Framework they can build one that's robust and secure at a fraction of the cost?

If you're about to commit significant resources to customized software and still want to sleep at night you need to check if what we're saying is correct.  Ask yourself today . . . do you really want to wake up tomorrow to find the Web 2.0 pundits have led you down a blind alley?

A Message From Our Architect

I've been developing computer software for more than 21 years.  When I first started we were using BASIC to perform the actuarial calculations in a consultancy firm.  Because I found computer programming so enjoyable I decided to take a position with an insurance company in Edinburgh, Scotland.  While I was there we used Pascal to develop policy and pension systems that were widely used throughout the United Kingdom.

After that I worked for a number of years in the retail industry in New Zealand where we made extensive use of C, C++ and RPG to develop customized business systems.  From there I went to work for a startup software company where we used Delphi to develop a successful retail and pharmacy package that is now used by the majority of pharmacies in New Zealand.

In February 1998 I became an independent contractor and started Responsive Software as a limited liability company.  Since then I've gained significant experience developing and maintaining software in many different contexts and in a variety of languages.  Our superior software service has been utilised by large and small organisations both inside and outside the computer industry.

More recently our lightweight Framework has allowed us to offer a whole new approach to the development of business software on the Windows platform.  Using our Framework a computer programmer (or team of programmers) can build a secure enterprise-level system as a single program that acts as both a client and a server.  This breakthrough in software architecture will radically alter the way customized software is done in the future once our infatuation with the Internet has subsided.

If the analysis of industry experts is correct and customized software is no longer an option programmers will be forced to abandon their craft or take one of the few remaining job vacancies still available at a SaaS datacentre.  But I'm delighted to tell you that this time the experts have got it quite wrong.  History is on our side - COMPUTER PROGRAMMERS OF THE WORLD UNITE - we have nothing to lose but our jobs!
