WHY WE'RE HIRING FOR THIS ROLE
We bill on consumption. Customers sign commitments, prepay balances they draw down against, ramp their spend each quarter, and go over — and contracts get amended mid-term. An invoice is only correct if someone understands both the contract and the usage data behind it, and revenue is only correct if someone understands what was actually delivered. Today nobody owns that end to end. We're hiring someone to own all of it: the billing run, the cash, the collections, the disputes, and the ASC 606 underneath. This is an operating job as much as an accounting one — some weeks you'll close the month, and other weeks you'll be the person getting a quiet six-figure account back on the phone.
WHAT YOU'LL DO
First 30 Days: Learning & Foundational Setup
Review our current ASC 606 processes and flag what doesn't hold up on a consumption model
Get into our metering and invoicing tools and find the first thing that's wrong — there will be one
Run daily invoicing and cash application, and tie the billing run back to contract terms
Answer billing inquiries and follow up on collection emails
Tell us what our DSO actually is, what's driving it
60 Days: Process Optimization & Operational Ownership
Take full ownership of order-to-cash — billing, AR, collections, and cash application
Own the conversation with the customers
Partner with FP&A, deal desk, Sales, and Customer Success so unusual deals bill correctly the first time
Work the aging deliberately: decide what gets chased, what gets escalated, and what isn't coming back
Take real work off the month-end close
90 Days: Process Improvement & Strategic Support
Lead revenue month-end close independently, from schedules to journal entries and support
Ship the billing improvements you identified in month one
Optimize usage-based rating so invoices are right before anyone has to check them
Build revenue and AR schedules an auditor can follow without you in the room
Tell us what to build, buy, or automate next, and why
WHO YOU ARE
This role needs both halves — order-to-cash operations and revenue accounting.
There is no one here to hand either of them to.
3–6 years across billing, AR and collections, and revenue accounting, ideally at a SaaS or usage-based company, including at least two years hands-on in order-to-cash
You have personally owned a receivables portfolio. Not supported one. You can tell us roughly what it was worth, what DSO looked like when you inherited it, what it looked like when you left, and what you did in between
You have run collections yourself — written the dunning sequence, made the calls, and decided when to escalate and when to write something off
You have configured a usage-based billing system setting up rating, plans and invoicing rather than only reading what the system produced
You have handled billing disputes directly with customers, including the ones where we turned out to be wrong
You have applied ASC 606 to consumption revenue: prepaid drawdown, overage, unused commitments, breakage and cutoff
You have owned or materially contributed to month-end close, and supported an external audit
You chase the discrepancy. When usage says one thing and the invoice says another, you find out why instead of filing it under immaterial
You are comfortable asking for money, and you hold your position when Sales asks you to pause a dunning notice during a renewal — without becoming someone they stop bringing deals to
You say what you don't know. When something needs a controller, a customer conversation, you flag it rather than quietly deciding alone
Bonus points for a CPA, comfort with SQL, or having built a billing process from scratch or migrated one system to another.
