A client document upload portal exists for one reason: to end the situation where the work is blocked because somebody has not sent something. Judged that way, most of the feature list is irrelevant. What matters is how many documents arrive, how quickly, and how few reminders it took. Four things move that number, and the upload limit, the drag and drop animation and the storage quota are not among them. This page is about the four, in the order they change the outcome.
Ask for named things, not for documents in general
An empty upload box asks the client to remember what you wanted. A named request does not: last year's return, the bank statements for March, a copy of the lease. Clients complete named requests at a far higher rate because there is no thinking involved, and your team gets a list of outstanding items instead of an inbox to reconcile. If a product cannot model the request itself, it is a folder with a login.
The phone is where the document actually is
Most of what you are asking for is either already a photograph on somebody's phone or is a piece of paper within reach of one. If taking a picture and sending it takes more than a few taps, the client waits until they are at a computer, and waiting until later is the same as not doing it. Test the whole path from your reminder message to a photographed document landing against the right client.
Reminders that stop when the thing arrives
Chasing is the cost you are trying to remove, so the reminders have to be automatic and they have to know when to stop. A client who has already sent something and gets reminded anyway stops reading your messages, which costs you every future reminder too. That means the reminder must be attached to the individual request, not to the client, and must be cancelled the moment the request is satisfied.
Questions people ask about client document upload portal
Is an upload portal safer than email attachments?
It is easier to control, which is most of the benefit: access can be removed, documents land against the right client, and nothing sits in an inbox indefinitely. Whatever your practice is required to do about client information is a matter for your regulator and your own adviser.
What file types should we accept?
Whatever your clients actually have, which in practice means photographs as well as documents. Refusing an image format is a good way to convert an upload into an email.
Should clients be able to see what they uploaded?
Yes. It prevents the most common support message, which is a client asking whether the thing they sent arrived, and it lets them notice themselves when they have sent the wrong year.
