National Carwash Solutions (NCS)’s finance team was spending more time navigating customer AP portals than collecting payments. With Monto, they cut DSO by 25 days and got 90% of the invoice-to-payment process running on its own, without adding any headcount.
ABOUT OUR CUSTOMER
The backbone of the carwash industry
For five decades, National Carwash Solutions (NCS) has kept the industry running. Home to brands like Armor All, Rain-X, Vacutech, TSS, and PurClean, NCS runs the most extensive service network in the business, giving operators everything they need to run efficiently and grow.
THEIR CHALLENGE
Buried under 60,000 invoices and 15 portals
NCS’s finance team had a volume problem: more than 60,000 invoices a year, spread across more than 15 customer AP portals, until getting paid had turned into a full-time operational job.
And every portal worked differently, with its own formats, its own approval chains, and its own rules for what an invoice needed to look like, so what should have been straightforward billing and collection became a maze, and DSO crept up to 71 days.
The problem wasn’t NCS’s customers. It was a growing pile of portals with no system holding it together, and a team that couldn’t keep up with the scaling.
USING MONTO
Cleaning up the mess, one portal at a time
NCS found Monto during a structured vendor evaluation, where three things stood out: high automation rates, ease of implementation, and the quality of customer support. They handed over their portal credentials and customer master data, and Monto did the rest.
Within 30 days, Smart Connections were live across their entire portal network: AI agents working inside each portal on NCS’s behalf. From there, Monto owned the full invoice-to-payment cycle, capturing invoices from NCS’s ERP, then enriching, validating, and submitting them to each portal in its required format. Issues got caught before they became rejections and were resolved mostly on their own.
For the first time, NCS could see every invoice, PO, and payment in one place, freeing the team from the portal grind so they could focus on cash flow and growth.
THE RESULTS
💰 DSO down from 71 to 45 days (25 days faster!)
By handling the full payment journey, from invoice delivery to exception resolution, Monto gave NCS a reliable, predictable collections cycle. Cash comes in sooner, working capital improves, and the finance team isn’t chasing payments across dozens of portals.
⚡ 90% end-to-end process automated
NCS went from 0% to 90% portal automation with Monto. Invoices are submitted, tracked, and resolved without manual effort across the vast majority of portal customers – finally freeing the team from repetitive tasks that used to consume their days.
✋ 84% not overdue, up from 58%.
More of NCS’s invoices are now paid within the agreed terms, rather than slipping past the due date. Monto catches errors and missing details before an invoice goes in, so it clears on the first pass instead of bouncing back and stalling the payment.
💪 Full visibility across all 15+ portals.
The NCS team now has a single dashboard that shows every invoice, every PO, and every payment, all normalized across all portals and updated in real time. No more logging in and out of different systems to understand where things stand.
Customer AP portals work well for the companies that use them. For a supplier like NCS, they mean another portal to learn with every new customer. Monto closes that gap, so NCS can get paid however its customers want, without the AR team carrying the load.
