I'm Rejiane Bryant, founder of One Stop Sourcing Group, helping growing B2B companies improve their customer lifecycle.
Most billing and collections problems start upstream, long before an invoice goes out.
My career has centered on customer lifecycle operations, from sales handoffs through billing and collections, and the teams behind them.
Again and again, I've seen billing problems start earlier: in an incomplete handoff, an unclear owner, or a record no one updated.
Today I pair that with clear, stable, documented processes, automation, and AI skills to cut the manual work.
Through One Stop Sourcing Group, I've brought my operations experience to organizations in technology, private industry, higher education, and government.
Leading customer and accounting operations teams, including domestic, international, and offshore.
Sales handoffs, onboarding, customer success, billing, AR, and collections.
Process development, controls, documentation, and cross-functional workflows.
Hands-on with CRM, billing, and accounting platforms, documentation tools, and AI-assisted automation.
Billing migrations, collections processes, and lifecycle cleanup. I've done the work I now help teams fix.
