Why teams switch
Collections is where cash gets stuck
Most finance teams spend the majority of their AR time chasing a small fraction of invoices. Monk automates the follow-up, portal submissions, and dispute routing. Your team works on the exceptions, not the routine.
Every AP portal your customers use, handled
When a customer requires Coupa, Ariba, or a proprietary portal, your invoice does not get paid until it is submitted correctly. Monk handles 600+ portals automatically. Every day of portal delay is a day your cash does not move.
Running in days, not 6 months
Most AR platforms require dedicated implementation teams and multi-month timelines. Monk connects to your existing ERP and CRM and runs first collections in days. No IT project. No waiting until next quarter.

What sets Monk apart from Tesorio
Tesorio is built to predict cash flow: when customers will pay, which accounts are at risk. But 39% of cashflow delays come from edge cases prediction does not touch: invoices stuck in AP portals, PO mismatches, unresolved disputes. Monk was built for those cases. Tesorio was built around the forecast. Monk was built around the relationship — execution, not prediction.

Tesorio predicts what will happen. Monk does the work.
Prediction does not move cash. Execution does.
A dashboard that surfaces risk is not an agent that resolves it. Monk works the invoice — the portal, the PO, the reply — without a human in the loop. And your forecast sharpens, because the data underneath it is action, not estimates.
39% of delays live in portals and edge cases
Monk handles 600+ AP portals automatically. Portal submission, PO mismatches, and unresolved disputes account for nearly 40% of cashflow delays. That is not Tesorio's problem to solve. It is Monk's entire product.
Live in days vs. months
Monk connects your ERP and CRM and runs first collections in 1–3 days; Tesorio implementations typically run 2 to 3 months. And Monk ships a public API, so your AR data stays programmable — never locked in a dashboard.

What switching looks like
Teams ask the same question: how long before Monk is actually running? Here is what the first 90 days look like.
Week 1
ERP and CRM connected
NetSuite, QuickBooks, or SAP connected. Invoice data imported. Salesforce or HubSpot synced. Customer contacts and AR aging mapped. Monk handles the integration. Your team does not touch it.
Day 7-30
First collections running. DSO baselineset
First automated outreach sequences live. AP portals identified and queued for automation. AR aging baseline established. You have a real-time view of what is outstanding and why for the first time.
Day 60
Portals automated. Aging improving
All AP portals configured and submitting automatically. Dispute playbooks tuned to your customer base. First measurable DSO reduction visible. Your team is working exceptions, not the queue
Day 90
DSO improvement confirmed. Teamfully off manual
Full collections running autonomously. DSO improvement quantified and reportable to leadership. Most teams have recovered more than the annual investment by this point.
Reviews
What our customers are saying
F&B
"As we scaled to hundreds of school districts, it became clear that our revenue operations needed the same rigor we apply to product and outcomes. Monk gave us immediate visibility into unbilled revenue, tightened our collections process, and became a true AR system of record – all without adding headcount. It allowed our lean finance team to operate with the discipline of a much larger organization."
Nico Serventi

“We evaluated a range of vendors as part of a thorough deep dive, in which Monk stood out above the rest with its unique collections tech, flexibility, and ease of use. That decision has continuously been re-affirmed.”

"We've used other contract-to-cash tools before, and Monk is in a different league. It's faster, and more importantly, it handles the edge cases that used to eat up our team's time, like AP portal submissions that we no longer have to think about. Monk's agents have already saved us hours every week by managing follow-ups on outstanding invoices, so we're not chasing down clients anymore. On top of that, the analytics and reporting have made life so much easier when it's time to report to leadership. What used to be a manual build is now a quick export. Beyond the product, the Monk team has been a great partner. They're incredibly responsive when it comes to feature requests and troubleshooting, and that level of support makes a real difference."

“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.”
Lucas Czajka

“We chose Monk to help automate our collections, a process previously demanding several hours a week of manual, one-off outreach. Today, our Monk agent is always running in the background and I have a single dashboard to manage AR from. George and the team provide exceptional service, are eager for feedback and ship insanely fast.”

Monk integrated with my systems in less than a week. They took over all invoicing and ensured I got paid on time. The platform handled the complexity of my wholesaler business and the team is available for support with same day response times.
