How Intuit Manages 10 Million Lines of Code 304

CowboyRobot writes "Intuit launched QuickBooks in 1992, and it has grown into the best-selling retail software for small-business accounting worldwide. QuickBooks is available on multiple platforms with different feature sets (Pro, Premier, Enterprise), in specialized editions (accounting, contracting, etc.), is available on CD or via subscription, and is offered in localized versions for the U.S., Canada, and the U.K. How they manage so many builds is a case-study for large scale programming. 'The Windows version is about 80,000 source files, 10+ million lines of C++ code plus a little C# for the .NET parts. Plus help files, tax tables, files defining local accounting rules, tax and other government reporting forms, upgrade offers — a lot of files. Every customer gets the full version. Specific feature sets are turned on and off with the license key.' And the lessons are not just technical. 'One surprising lesson is that small teams work, even for very large codebases — especially, Burt says, in sustaining an entrepreneurial, creative culture.'"

    Quicken and Quickbooks is the only application I know of to have survived a full-on Microsoft assault on their business. Microsoft Money has folded. It's something to be proud of, I guess - for now.

    The last time that I tried to contact Intuit about Quicken on Linux was a mess:

    I certainly hope that they handle their code better than they handle their customers.

    Quickbooks and Quicken are similar only in that they are owned by the same company. They are not related in any other way. It sounds like you're giving too much weight to the "Quick" part of the names.

    Sage Peachtree is the main competitor in the self hosted small business accounting realm. To be honest if my dad wasn't so opposed to a hosted solution I would have had him go that way as even with 5 users the cost difference once you add up the server and licenses wasn't that great over five years.

    As far as QB goes, it seems to finally be ok. Up until 2007 it still couldn't run as a limited rights user and required short printer names both of which caused me serious pain as I was the IT department for a midsized accounting firm and getting QB running in Citrix was NOT fun. We had premier enterprise support and their answer to the LRU issue was to grant Everyone full rights to HK_Classes_Root (NOT a good idea). I eventually figured out what keys the user needed access to and published the solution online to help others but their spaghetti code was so bad even then that nobody could actually tell what it was doing to give me the right answer.

    They probably do owe their continued existence to Microsoft since their 1997 deal ($150 million investment).

    Bologna. I've been using Gnucash for years on a sizable business with no problem. I'm also very familiar with QuickBooks (I worked as a staff accountant for several years). Sure, there's a lot that quickbooks can do that Gnucash can't, but there's nothing fundamentally missing from Gnucash to prevent someone from using it for business purposes. If FOSS means anything to you, Gnucash is the only way to go.

    I disagree. As long as your books are kept correctly, the accountant only needs three things:

    1) Profit and Loss 2) Balance Sheet 3) Depreciation Schedule

    Gnucash does all of those. Print them out. Hand it to your account. And you're done.

    As a small business owner using GnuCash, it's not quite that simple. Accountants like using tools like QuickBooks that they are very familiar with, and they don't want to have to re-enter all the data. So printing out the information is useless for them. You really need to export it to a format that both support.

    Sadly, GnuCash does not support exporting Quicken/QuickBooks formats. It will important them with some extra file filters, but no export capability. My solution is to export to CVS which QuickBooks can import as well. Haven't tried it yet, but my accountant & I will be working through it when the time comes.
