FileThis is an excellent service that I use all the time. You can connect the service to all of your bank accounts, insurance, and many other accounts. FileThis will then periodically check for new documents and download them automatically to either your computer or a cloud service. They will each be saved in their separate folders for easy organization.
I know some websites will only provide so many back statements. If you want older reports over a year, then you may need to send a special request. I like to have copies of all my statements readily available. I used to try and download them myself every month or scan statements sent to me by mail. Often, I would forget and become complacent. Now I do not have to worry as FileThis will do it for me.
