The two sites are similar at first glance. Both allow you to upload bank information, sync bills for utilities and credit cards, add payment-due alerts, and even view travel miles and investment statements. Unlike the very popular Mint.com, they don’t break down your expenses, but both services do organize your bills so that it’s easier to see what you spend over a long period of time.
Although both services have mobile apps and a Web version, the PageOnce mobile companion is available on a wider range of operating systems. And you might appreciate the fact that PageOnce has never had a security breach since launching in 2008. Manilla, which also promises bank-level security, hasn't experienced a breach, either; but since that site is brand-new, it’s too early to compare track records.
Manilla allows customers of companies such as Citibank the option of eliminating some physical junk mail and getting offers through Manilla's online mailbox instead. Also, the site stores copies of all your bills indefinitely (unless you delete them) and allows you to download copies of bills to your hard drive.
Ultimately, you’ll want to choose between the two sites by visiting each and seeing which services and sites can sync with them. Major services and institutions such as AT&T, Chase, and Netflix are available on both platforms, but Manilla offers Groupon and magazine-subscription syncing, whereas PageOnce can sync with the U.S. Department of Education loan office.
If you’re the type of person who always gets lost in bills, Manilla or Pageonce will help you take a critical look at everything you’re spending money on each month, and will remind you of any rewards you may have earned through loyalty programs (such as airline mileage from credit cards). Either site offers a great way to keep on top of your expenses.
