Part Time Business Development Manager Jobs in Pennsylvania

Location: Philadelphia, PA / South Jersey / Delaware

Job Type: Hybrid

Compensation: $60,000–$80,000 base + uncapped commission (OTE $200,000-$250,000/year - W-2)

Do you love the thrill of opening new doors, building real relationships, and closing deals, but you're tired of selling something you don't believe in? This one's different.

We are partnered with a well-established public accounting and advisory firm with a rock-solid reputation across New Jersey, Southeast Pennsylvania, and Delaware. They provide tax planning and preparation, audit and assurance, bookkeeping and controller services, and CFO advisory support for manufacturers, property managers, professional services firms, and privately held businesses. The work is precise, deadline-driven, and built on trust. Clients stick around because the firm does it right and they care about the relationships.

Here's the thing: they've grown almost entirely on referrals and reputation. That's a great problem to have, and it also means there's wide-open room for the right Business Development Manager to build something real. They are not looking to invest in just anyone for the Business Development Manager role. We want someone who's excited to build that engine, not someone walking into a fully-formed machine. We are looking for someone reliable, trustworthy, experienced, an expert in the field, disciplined, charismatic, and eager.

What you'd actually be doing: You'll own the front end of our sales process by prospecting, discovery, and opportunity development. You'll work directly with the President/Owner to scope engagements and get deals across the line. No layers of bureaucracy. No waiting weeks for a decision. Just you, a real target list, and a leadership team that moves fast.

• Prospect new business through calls, email, LinkedIn, networking, and partner referrals
  
• Build relationships with business owners, CFOs, controllers, and operations leaders
  
• Run discovery calls, coordinate in-person meetings, and qualify opportunities
  
• Manage a real pipeline from stages, next steps, close dates, and clean CRM notes
  

• Partner on proposals and present solutions directly to decision-makers

• Work alongside referral partners (attorneys, bankers, and financial advisors) on co-selling
  
• Track your own activity and results, and help shape the process as it's being built
  

What we're looking for:

• 2+ years of B2B sales or business development experience (professional services, accounting, financial services, or consulting backgrounds are a great fit, but not required)
  
• Experience in professional services sales, accounting/advisory business development, or marketing is ideal
  
• A real track record of prospecting through cold calling, cold email, and the follow-up discipline to make it work
  
• Confidence speaking with owners and executives just as easily as finance or operations staff
  
• Self-direction - you can set and hit your own weekly activity goals without someone looking over your shoulder
  

• Valid driver's license and the ability to travel locally for client meetings

Why this role is worth a serious look:

• Direct access to ownership, your ideas get heard, and decisions happen fast
  
• A genuinely strong practice and reputation to sell, with a loyal repeat-client base
  
• Real differentiation in the market: experienced advisors, deep industry knowledge, and a client-first approach
  
• A base of $60,000–$80,000 plus uncapped commission, structured around deal specifics
  
• Flexibility for the right person. Full-time is preferred, but we'll consider a strong part-time or contract arrangement
• Where you'll work: This is a hybrid, field-based role covering Philadelphia and the nearby NJ/DE area. You'll be on the road for client meetings, with flexibility to work remotely otherwise.

If you're a self-starter who knows how to open doors and build trust, and you want a seat at the table while we continue to build, we'd love to talk.
