About the Opportunity:

Market Once is hiring a Lead Revenue Accountant to own revenue accounting and customer invoicing across Market Once and its companies, eAccountable and ROI Rocket. This senior individual contributor leads accounting for a high-volume, multi-entity billing operation that processes hundreds of invoices each month, including for key enterprise clients who expect exceptional accuracy and professionalism.

This is a hands-on, build-and-fix role. You will process and post invoices yourself while redesigning a manual, multi-step billing workflow that spans five contributors and moves data from our ERP/project management system into Great Plains. You will determine the correct revenue treatment for our agency and research engagements, including pass-through costs, and turn those conclusions into clear, documented processes.

Working with minimal supervision, you will partner with senior executives and team leads across the business to understand how billing inputs are created, resolve problems at the source, and give finance leadership accurate revenue data, reconciliations and projections. The ideal candidate thrives in ambiguity, enjoys untangling messy processes, and takes full ownership of getting revenue right.

Process Improvement and Documentation (~25%)

• Assess the current invoicing workflow, which involves five contributors, by meeting with team leads to understand their roles, inputs and pain points
