What should a customer portal actually do?
The useful test is which emails it removes. A portal earns its keep when it answers the questions your customers currently ask by email — where is my order, what did I agree to, can I have that document again, what do I owe. Everything beyond that is worth questioning. Portals fail more often from doing too much than from doing too little.
Is it safe to let customers see our data?
It is, provided access is designed rather than assumed. Every request has to check who is asking and what they are entitled to see, on the server, on every call — not merely hide the wrong buttons in the interface. We build the permission model first and test it against the case that matters: a real customer account trying to read another customer's record.
Can it connect to the systems we already use?
Yes, and it generally must, because the data a customer wants to see already lives somewhere — an accounting system, a CRM, an internal tracker. The portal reads from those rather than becoming a second copy that drifts. Where a system has no usable API, we can often work from exports, and we will be straight about the trade-off before you commit.
Do our customers need to install anything?
No. It runs in a browser on a phone or a laptop, behind a login. A native app only makes sense when you need something the browser cannot do — offline use, camera work, push notifications — and that is a separate conversation rather than an assumed part of a portal.
