Mark43New York, New York, United States · Posted 2 months agoDescription
Applicants must be authorized to work for any employer in the country in which the role is being hired. We are unable to sponsor or take over sponsorship of an employment visa at this time.
Mark43's mission is to empower communities and their governments with new technologies that improve the safety and quality of life for all. We build powerful, scalable, and elegant software that sets a new standard for the tools upon which our first responders rely. Our users are diverse, and we are committed to embracing diversity of thought and experience within our team.
Mark43 partners exclusively with U.S. government agencies across federal, state, county, and local jurisdictions, as well as government agencies in the United Kingdom. Our customers operate in complex procurement, budgeting, appropriation and invoicing environments. We are looking for a Senior Collections Specialist with public sector experience to improve cash collections, reduce days sales outstanding, and strengthen our public-sector order-to-cash process.
Role Summary
Mark43 is seeking a highly motivated Senior Collections Specialist, Public Sector to support collections and accounts receivable activities for our government customers. This is a hands-on role for someone who understands that collecting from government customers requires more than sending invoice reminders.
The ideal candidate has experience working with or collecting from public-sector entities, including cities, counties, states, federal agencies, law enforcement agencies, public safety departments, school districts, transit authorities, or other government organizations. You understand how government payment processes work, including annual appropriations, purchase orders, encumbrances, invoice approvals, auditor or controller review, council or board approvals, milestone acceptance, and supporting documentation requirements.
In this role, you will partner closely with Revenue Accounting, Customer Success, Sales, Deal Desk, and Professional Services Implementation teams to identify and resolve payment blockers. You will help ensure invoices are submitted with the right documentation, purchase order details, billing references, and customer approvals so that Mark43 can reduce avoidable delays and improve cash predictability.
What You’ll Do
- Support collections activities for Mark43’s public-sector customer portfolio, with a focus on reducing DSO and accelerating cash collections.
- Identify, document, and resolve payment blockers related to missing purchase orders, insufficient PO balances, annual appropriations, invoice approval workflows, customer acceptance, contract references, and supporting documentation.
- Help create and maintain customer-specific payment profiles, including fiscal year, budget cycle, PO requirements, AP portal instructions, approval contacts, payment run cadence, council or board approval thresholds, and escalation paths.
- Proactively follow up on upcoming annual renewals, recurring invoices, and milestone billings to confirm that required POs, funding, and customer approvals are in place.
- Partner with Revenue Accounting to ensure invoices include required PO numbers, contract references, billing periods, milestone support, tax-exempt treatment, remit-to details, and agency-specific invoice requirements.
- Escalate payment issues professionally and appropriately when customer payment blockers require support from other stakeholders.
- Help improve internal playbooks and processes for government collections, including common public-sector payment scenarios such as non-appropriation, council or board approvals, auditor review, grant-funded invoices, and advance-payment restrictions.
- Assist with collections reporting, cash forecasting inputs, AR aging reviews, and support month-end close activities by providing timely status updates on outstanding receivables, expected cash collections, and high-risk invoices.
What You’ll Need
- 6+ years of experience in collections, accounts receivable, credit and collections, billing, revenue operations, public-sector finance, government contracting, or a related finance function.
- Experience collecting from or working directly with government entities, including federal, state, county, municipal, public safety, or other public-sector customers.
- Understanding of government payment processes, including purchase orders, encumbrances, annual appropriations, invoice approval workflows, auditor/controller review, governing body approvals, and prompt-payment expectations.
- Ability to read and interpret contracts, order forms, statements of work, purchase orders, billing schedules, invoice terms, and customer payment requirements.
- Strong customer-facing communication skills, including the ability to follow up on past-due invoices while maintaining positive customer relationships.
- Strong cross-functional collaboration skills, with the ability to work effectively with across stakeholders and executive leadership.
- High attention to detail and strong organizational skills.
- Ability to manage multiple customer accounts, payment issues, deadlines, and escalation paths at the same time.
- Experience using NetSuite, Salesforce, billing systems, collections tools, customer portals, or similar systems.
- Strong analytical skills and ability to identify trends in aging, DSO, payment delays, and collections root causes.
- Comfort operating in a fast-paced environment where processes are still being improved, documented, and scaled.
What Success Looks Like
Within the first 90 days, you will have become familiar with Mark43’s government customer portfolio, collections process, billing structure, and highest-risk receivables. You will have built relationships with internal stakeholders and begun identifying the primary drivers of delayed payment across assigned accounts.
