Somewhere in your inbox, between a meeting invitation and a newsletter you'll never read, there's an invoice that was supposed to be approved last week. You forwarded it. Someone replied. But the thread has forked into three conversations and one attachment might be the updated version - or might be the original.
This is what happens when email gets pressed into service as an approval system, a document repository, and an audit trail. It can't do any of those jobs reliably. But by the time you realize that, your entire AP process is buried in threads nobody can untangle.
A consultancy processing around 400 AP invoices a month described it clearly:
"It's very much a case of emails, email approvals. And it's so easy for data and information to get lost in the ether."
When your audit trail is someone's inbox, it exists only as long as they don't archive, delete, or simply miss the message.
The real damage shows up in the time it eats. At the same firm, the impact on one team member was staggering: "A good 50% of his day is spent processing invoices, chasing approvals, trying to find the trail of when they last chased them." Half a working day, every day, spent navigating email threads.
A manufacturing business with multiple departments saw the security angle too: "Operational expenses are typically done by email. From a security point of view and traceability, it's terrible." Anyone can forward an invoice. Anyone can reply "approved." There's no verification that the right person approved the right version of the right document.
At a construction company, the burden fell on one person: "We haven't been able to enforce anything because Amy's managed it through her emails. Quite a bit of a burden on Amy having to chase everyone all the time." When one person holds the process together through sheer force of memory and follow-up, you don't have a system. You have a single point of failure named Amy.
And for some businesses, the reckoning comes from outside. A KPMG auditor told one securities firm directly that automated approvals would be in scope for their next review. At that point it was no longer optional.
