Managing multiple client portals can cost vendors a full workday a week

Adding one new client portal doesn't just add one more login. It adds a login on top of every other one already slowing a vendor down, and the time cost of that stack isn't additive. It's closer to compounding.

The escalation, in numbers

Vendors managing zero client portals mostly get away with a light admin load: only 10.4% of them spend 6 or more hours a week on portal work. That share doesn't creep up gradually as portals get added. It jumps.

Vendors juggling 1 to 2 portals already see that heavy-admin share triple, to 33.7%. At 3 to 5 portals, it nearly doubles again, to 59.5%, meaning most vendors in that bracket are now losing most of a workday every week just to logins, uploads, and status checks. By 6 to 10 portals, 80.0% of vendors are in that heavy-admin group. Past 10 portals, it's close to universal. (The two largest brackets, 11 to 20 portals and more than 20, are based on small samples of 9 respondents each, so treat those endpoints as directional rather than precise.)

Why "just a couple portals" is already a lot

Most vendors aren't managing a sprawling stack. 46% log into just 1 or 2 portals a month, and on paper that sounds manageable. But a third of that same group is already spending 6 or more hours a week on portal admin, which means the jump from zero portals to a handful is where most of the damage happens, long before a vendor is anywhere close to what most people would call "a lot" of portals.

What actually eats the time

None of this hour count comes from doing the job. It comes from logging into a separate system for every client, checking on invoice status that isn't visible anywhere else, and resubmitting whatever a portal rejected the first time. Each portal is a small task on its own. The problem is that none of them go away, and every new client adds one more that has to be checked on a recurring basis, forever, not just once during onboarding.

The same growth penalty, a different shape

This tracks with something else in this data. Larger vendors already wait longer to get paid, largely because bigger clients route payments through more layers of approval. Portal count tells a similar story from a different angle: growth doesn't just mean more approvals to wait through, it means more separate systems to maintain. Vendors don't get a break from admin as they scale. They get a second, compounding cost stacked on top of the first.

Portal admin time is one piece of a bigger picture. The 2026 Vendor Payment & Portal Report covers how 417 vendors handle payments, compliance, and tooling overall, and the summary: 2026 vendor payment report rounds up what else stood out.
