Senior Functional Consultant

The Senior Functional Consultant serves as the critical bridge between e-invoicing regulatory mandates, business processes, and technical implementation teams. You will translate complex global e-invoicing and transaction control (CTC) requirements into structured, applicable designs that ensure successful implementation across Avalara's E-Invoicing and

Live Reporting (ELR) ecosystem.

Working closely with mandate subject matter experts, engineering teams, ERP connector teams, implementation consultants, AI partners, and strategic technology partners, the Senior Functional Consultant ensures regulatory requirements are consistently interpreted, documented, and implemented. You will combine knowledge of Procure-to-Pay (P2P) and Order-to-Cash (O2C) processes with technical consulting and solution design capabilities.

The Senior Functional Consultant is both a trusted advisor and implementation lead, helping accelerate customer onboarding, reduce deployment friction, improve implementation consistency, and promote successful customer outcomes
