Map the client’s month
Think through what a typical client does in a month. They might raise invoices, enter or approve bills, check whether customers have paid, answer a question from your team and read a monthly report. Write those steps down in order, then note which tool or channel each one currently uses.
Most firms find the answer is scattered: some tasks happen in software, some over email, some through file-sharing links. Every switch between channels adds friction and a chance for something to go missing. The goal of a portal experience is to bring as many of those steps as possible into one place.
