Invoice Butler runs the entire collections workflow for B2B companies using AI and human operations: chasing unpaid invoices, managing AR inboxes, handling supplier portals, and resolving payment issues so finance teams collect cash faster without adding headcount.
We combine AI automation with human operations to run the entire collections workflow for companies from Series A startups to $100M+ revenue businesses.
Our platform and operations team:
• Manage collections end-to-end
• Run AR inboxes
• Handle supplier portal uploads (Coupa, Ariba, etc.)
• Parse remittances and apply payments
• Escalate disputes and unblock invoices
• Drive real cash movement
Today, Invoice Butler manages over $1B in accounts receivable across our customers.
We work with some of the fastest growing companies in software and AI — and demand is growing faster than we can onboard customers.
We're now hiring a Customer Success Manager to help us scale the next phase of the company.
This is not a traditional CSM role.
You won’t just “manage relationships.”
You will own outcomes.
What This Role Actually Is
Every customer hires Invoice Butler for one reason:
They want invoices paid faster.
Your job is to make that happen.
You will own a portfolio of customers and be directly responsible for:
• Delivering ROI within the first 90 days
• Ensuring customers see real cash acceleration
• Preventing churn before it happens
• Expanding accounts as customers grow
You will operate more like a revenue owner than a traditional CSM.
If you enjoy driving results, pushing teams forward, and solving operational problems, you’ll thrive here.
If you want a comfortable “check-in call” job — this isn’t it.
What You’ll Do
1️⃣ Close the Second Sale (Post-Sale Success)
Every customer has a 90-day success window.
You will:
• Define clear success metrics (cash collected, DSO improvement, hours saved)
• Run a structured onboarding plan with milestones at Week 2 / 4 / 8 / 12
• Identify risks early and address them head-on
• Ask hard questions early:
“If renewal were today, would you renew?”
If something isn’t working, you will not wait until month three to discover it.
2️⃣ Run Accounts Like a Business
You will own a book of customers and treat it like your own portfolio.
That means:
• Monitoring invoice aging and collections progress
• Working with our operations team to unblock payments
• Ensuring AI automation and workflows are working correctly
• Helping customers improve how they run AR
You are responsible for making sure customers actually feel the impact.
3️⃣ Expand Accounts
When customers see results, they expand.
You will:
• Identify expansion opportunities
• Introduce new capabilities (supplier portal automation, inbox management, etc.)
• Help customers roll Invoice Butler out to more of their finance workflows
The best CSMs here operate like consultative salespeople.
4️⃣ Push Internally to Solve Problems
You will work closely with:
• Operations (collections execution)
• Engineering (automation + integrations)
• The founders (strategic accounts)
If something is blocking a customer, you escalate and get it fixed.
You are not passive.
You move things forward.
Who Thrives In This Role
You likely have 3–8 years of experience and come from one of these backgrounds:
• Former SDR or AE who likes owning outcomes more than chasing quotas
• RevOps or Finance Ops operator who understands how revenue actually moves
• Customer Success leader who prefers impact over relationship management
You are:
• Competitive
• Analytical
• Direct
• Comfortable with intensity
• Comfortable having difficult conversations
• Obsessed with execution
You are not:
• A “smile and wave” relationship manager
• Someone who waits for instructions
• Someone who avoids pushing customers or teammates
