OneReceipt is a hub for every receipt in your life, whether it's in your email account, saved as a PDF, or in paper form. It will ll help you track them all easily and with the minimal amount of effort, making it simple to both keep and analyse a comprehensive purchase history.
What Does It Do?
OneReceipt works by first connecting to your email accounts to pull any receipts it can find. (Currently only Gmail and Yahoo! are supported.) It'll take some time to process, but you can see the results as it builds them. You'll get an overview of all your purchases that you can browse in chronological order, filter on a variety of criteria, and search. OneReceipt also provides analytics so you can see your spending month-to-month and where that money went.
On top of all that, you can add paper receipts as well. OneReceipt provides you with a personal email address which you can use to forward electronic and paper receipts for processing. You can also use that email address when you provide your contact information to a company. This way you don't have to give out your real email address. OneReceipt will know the different between messages from you and messages from other people, and so those other messages will be stored in a special section of the site. All of this makes it a really handy online and offline shopping companion.
Wait, This Sounds Familiar...
If any of this sounds familiar, that's because OneReceipt is similar to previously mentioned Slice. Slice also pulls receipts from your email and creates a purchase history. OneReceipt is a better option in that department because it takes the concept a bit further, but Slice has one handy feature that OneReceipt doesn't: package tracking (though that's less useful for most Aussie readers). Slice also provides notifications for when a price drops and you are still within a price adjustment window from a particular merchant.
Since there's really no harm in using both, that's what I'm doing at the moment. OneReceipt is where I'll go for my receipts and spending analysis. (Turns out I did a good job of cutting back this year, woo hoo!) Slice is where I'll go for package tracking, since it pulls everything from my email so I don't even have to bother entertaining tracking numbers. It'd be great if both web apps were one and the same, but for now they're similarly useful in conjunction.
