How Pump consolidated its AR workflow and built a real-time source of truth with Monk

“At Pump, we manage $25M in volume across 1,500+ customers, and before Monk, a huge part of collections was still manual. The product is extremely customizable and has already helped us collect over $10M in just the last couple of months. What really sets Monk apart, though, is the team. There are plenty of collections tools on the market, but the level of care and commitment from Monk has stood out from day one.”

Overview

Pump, the leading platform for cloud cost optimization, partnered with Monk to bring its entire billing and collections operation under one roof as the business scaled from $1M to $25M ARR in 18-months.

Pump now has collections infrastructure that can keep pace with its growth. Follow-ups are consistent, collections are more effective, and the manual overhead that came with managing each customer individually has been replaced by automated workflows that scale without adding operational burden.

Challenge

The challenges were clear for Pump:

  • Pump is growing rapidly and expanding its customer base faster than its existing billing and collections infrastructure was built to support.
  • Follow-ups, payment tracking, and reconciliation had accumulated organically over time, shaped around individual customers rather than a coherent workflow.
  • As volume grew, inconsistent processes and the absence of a single source of record meant the team was spending meaningful time on manual work that should have been automated.
  • As Pump's ARR scaled, nailing its collections workflow was critical. The team needed infrastructure that could grow with the business, rather than a set of workarounds that demanded more manual effort with every new customer added.

Our Solution

Pump chose Monk for its intelligent collections design, integration depth, and the responsiveness of its team.

Scalable collections infrastructure. Monk gave Pump a single platform capable of handling collections at scale - consistent automated follow-ups, centralized account visibility, and workflows that don't break down as customer volume increases. The customer-by-customer inconsistency that had built up over time was replaced with a repeatable, auditable process.

Clean integration with existing tools. Monk connected directly to the accounting, banking, and CRM tools Pump already used. Payment activity and invoice status stay synchronized across the stack without manual reconciliation.

A team that moves quickly. Monk's team engaged closely throughout advising on process design, responding to feedback, and shipping improvements in real time. When workflow gaps came up, they were addressed fast. Pump went live quickly and saw tangible results within the first billing cycle.

The broader impact has been both operational and financial. For the first time, the team has a reliable, real-time picture of AR, DSO, and cash flow all in one place, giving leadership the visibility it needs to forecast with confidence and make decisions as the business continues to scale.

Manual AR is death by a thousand cuts
