Client Onboarding & Implementation Project Manager

Rentvine, LLC.; Estero (FL); On-site; USD 95,000 - 125,000; Full time

Job summary

Rentvine is seeking a seasoned Project Manager to lead client implementations for our SaaS platform. You’ll own the plan, manage data migration and configuration, and ensure on-time delivery from kickoff to handoff. You’ll write SOWs, determine scope, and coordinate with Sales for complex deals while guiding teams to successful go-lives.

Strong writing and stakeholder communication are essential. You’ll be deeply involved in data validation, budgeting, and keeping plans current for multiple

Qualifications

• 4+ years running customer-facing implementation, onboarding, or professional services projects — B2B SaaS ideally
• Real experience scoping work and writing SOWs. We’ll ask how you estimate, and what you learned the time you got it badly wrong
• Comfort walking into a conversation cold. You’ll be scoping accounts where you don’t know anyone, sometimes before there’s a signed deal, and you need to build enough trust in one call to get straight answers about their data and their operation
• Experience carrying a full portfolio at once. Be ready to talk specifics: how many, how long they ran, how often you hit your dates
• Solid project management fundamentals — scope, dependencies, critical path, risk tracking, change control, status reporting
• You keep your project tool current. Not most weeks. Always
• You can get people to deliver without managing them
• Good judgment on scope and commercial tradeoffs, the backbone to hold a position with a client, and the sense to know when to escalate
• Strong writing. SOWs, change orders, and status updates all fall apart when they’re vague
• Clear, calm communication out loud too, especially when the news isn’t good
• Comfortable in Excel and Sheets — lookups, conditional logic, cleaning up messy legacy exports — enough to build a migration file when you need to
• Enough financial literacy to poke at a migration and know when something’s off. You don’t need to be an accountant; we have those

Responsibilities

• Own the project: run client implementations end to end from kickoff to go-live and post-launch weeks
• Build robust project plans covering discovery, data migration, configuration, training, and cut-over
• Define scope at kickoff and align client expectations on timelines and deliverables
• Manage scope changes with impact analysis and client agreement
• Keep project status clear so a teammate could take over at any time
• Scope work and write SOWs for internal teams or partners as needed
• Write change orders with timelines and effort impacts, client sign-off required
• Collaborate with Sales on complex deals to scope before signing
• Help build templates and estimation standards for consistency
• Run risk reviews and ensure go-live readiness against exit criteria
• Lead client communications as the single point of accountability throughout
