1. A computer implemented method for attaching a file to an electronic record of an insurance claim or insurance policy, the method comprising: receiving, via a computer network, at a backend server associated with a first entity, a first file originating from a client device associated with a second entity, wherein the first file is in a first format and the first file corresponds to an insurance claim; determining, at one or more processors of the backend server associated with the first entity, whether the first file meets a supported threshold value; wherein, if it is determined that the first file format does not meet the threshold value, converting, at the one or more processors of the backend server associated with the first entity, the first file to a converted file, wherein the converted file meets the supported threshold value; transmitting, from the backend server associated with the first entity, over the computer network, the converted file to the client device associated with the second entity, for a confirmation from the client device associated with the second entity, that the converted file is appropriate for attachment and that the converted file has a sufficient level of detail for processing of the insurance claim; receiving, at the backend server associated with the first entity, the confirmation that the converted file is appropriate for attachment and that the converted file has the sufficient level of detail for processing of the insurance claim, wherein the confirmation is received in response to the confirmation transmission and the confirmation originates from the client device associated with the second entity; attaching, at the one or more processors of the backend server associated with the first entity, the converted file to the electronic record of the insurance claim or insurance policy; and storing the converted file on a storage medium.
