I’ve been researching ways to consolidate bank account information into a single, automatically updating view. There are a couple of new web-based options - most notably Wesabe and Mint - but those have a consumer focus. I’m more interested in viewing trends in our business - a real-time financial dashboard.
Open Financial Exchange (OFX) Standard
In January of 2007, the Open Financial Exchange standard was announced by Microsoft and Intuit. Many financial institutions provide support for a portion of the standard, namely the portion used by Quicken.
Retrieving OFX data
Once you obtain the OFX connection details for a financial institution, you can then connect to it to retrieve financial transactions. Getting to this point often isn’t straight forward. For many banks, the online login information isn’t the same as the data needed for the OFX connection. Some banks, like Wells Fargo, charge a monthly fee for OFX access. Finally, chances are your bank’s customer support line won’t know anything about OFX. Your best bet is to ask how to enable Quicken access (which uses the same OFX standard).
There are a couple of libraries available for retrieving OFX data:
OFX for Ruby is similar to LibOfx, but obviously in Ruby. There are a couple of examples included in the library download.
In general, retrieving this data isn’t a straight forward process. OFX connection details are scattered, some banks haven’t made it easy to enable OFX, and there isn’t much information available on building an OFX client. It’s definitely primitive.
Additionally, OFX transactions can be cryptic - a large part of Wesabe’s value is in its ability to provide better transaction formatting.
How are others doing it?
With Wesabe, you record a Firefox browser session, walking through the download process. You can then re-run the session and Wesabe then updates your account data using the script.
Mint provides the most seamless experience. You simply provide your bank details (even PayPal works) and it grabs your transactions. Mint uses “Yodlee” to actually connect with financial institutions. Yodlee has been doing this for a while - they have a service called MoneyCenter that is remarkably similar to Mint - it actually has more features but lacks Mint’s visual appeal. My guess is Yodlee charges a pretty hefty licensing fee.
I wouldn’t bet on banks making it any easier to automate data retrieval. Erick Schonfeld of Techcrunch recently wrote a post that covered the API landscape very well - which types of companies are most likely to offer APIs and why companies that push APIs are very careful with what they are actually opening up. Opening up a core component of your business can spur some pretty dramatic changes - it will take a younger, upstart bank to spur progress.
While it’s not here yet, I’d pay for a service that:
Made connecting to financial institutions as easy as Mint (just a user name and password - no OFX connection details needed)
Scrubbed transactions like Wesabe
Published an API for retrieving this data that didn’t require a customer account (in other words, the ability to query for bank account transactions from an account not directly setup through the provider)
