Hadrius cuts DSO from 82 days to 11 with Invoice Butler

Hadrius, the AI-native compliance platform for SEC- and FINRA-regulated financial firms, serves hundreds of institutions, and every one of them gets invoiced. Before Invoice Butler, collections was a manual process, and Austin Kim, Founding Operations Lead, was the person doing it: writing and sending payment follow-up emails himself, one at a time, while DSO sat at 82 days and earned revenue stayed stuck in accounts receivable.

‍

The stakes made it harder. Hadrius sells to top financial institutions, customers that are both extremely important and extremely sensitive. Speeding up cash collections and reducing DSO without affecting those relationships wasn't a nice-to-have. It was the whole requirement. 

‍

A clumsy automated dunning email to the wrong customer could undo months of goodwill.

When the team surveyed the market, nothing fit. On one side were billing tools with basic automation bolted on. 

‍

On the other, full AI tools with no judgment about when a human should step in. Nothing threaded the needle with an AI-native solution built for collections that still treated every customer interaction with care, until Invoice Butler came along.

Hadrius handed invoice collection to Invoice Butler, and the process Austin used to run by hand is now completely automated. Invoice Butler's AI handles the repetitive work of tracking invoices, following up, managing the AR/billing inbox and collecting payment, while a human in the loop reviews every customer-facing interaction so each one lands with the care Hadrius's customers expect.

‍

It's not a set-and-forget vendor relationship, either. 

The Invoice Butler team works closely with Hadrius on an ongoing basis, getting involved directly, tuning the collections motion, and handling the judgment calls that matter with sensitive accounts.
‍

The result is a full collections function with zero new hires, one that runs itself without ever feeling automated to the customer.

With Invoice Butler running collections, Hadrius cut DSO from 82 days to 11, with payments arriving 7x faster, and now collects 90% of invoices. They did it without hiring a single person internally, saving the cost of a collections function on top of the revenue pulled forward, and the customer relationships that make Hadrius's business work stayed intact.
‍

The results were worth celebrating, literally: Austin showed up at Invoice Butler HQ with a cake from the Paris Baguette nearby and did the math on the spot.

‍

Austin's time went back to the work that grows the company, and Thomas's advice to other finance leaders is simple: don't hesitate.
