Grow Your Estate Sale Business: How IESP Training & the CESF Certification Turn Beginners Into Trusted Pros
Whether you're thinking about starting an estate sale company, just opened your doors, or you've been at it a few years and feel stuck, the Institute for Estate Sale Professionals (IESP) gives you the training, systems, and credentials to grow with confidence. And as IESP's industry partner, EstateSaleFinder gives every IESP student 3 months of Pro Plus free.

Running an estate sale company is one of the most rewarding small businesses you can build. You help families through some of their hardest moments, you turn a lifetime of belongings into real money for the people who need it, and you get to work with history, beauty, and treasure every single day. But almost nobody hands you a playbook for *how* to do it well — so most operators learn the expensive way, one painful mistake at a time.
That's exactly the gap the Institute for Estate Sale Professionals (IESP) was built to close. Founded by Jenna Pecor — the estate sale pro behind Jennarocity Estate Sales, with 12+ years in the field — IESP is the umbrella organization that turns hard-won, real-world experience into clear, repeatable training and a respected industry credential. And here's the part we're genuinely excited about: EstateSaleFinder has partnered with IESP, and every IESP student gets 3 months of Pro Plus free on our platform. More on that below.

Who this is for
IESP was designed for estate sale company owners at every stage of the journey:
- Thinking about starting one — You love the hunt, you're great with people, and you've wondered if you could turn it into a business. IESP shows you how to start the right way instead of guessing.
- Just launched — You've run a few sales, but pricing, contracts, and sale-day chaos still keep you up at night. IESP gives you the systems to stop reinventing the wheel.
- A few years in and stuck — You're good at the work, but growth feels like pushing a boulder uphill. IESP helps you professionalize, raise your rates with confidence, and finally scale.
No matter where you are, the lesson is the same one Jenna learned: you were never not good enough — you were just missing the training and the tools.
Meet Jenna and the IESP mission
Jenna Pecor spent over a decade building a thriving estate sale company from the ground up, making every mistake so you don't have to. She founded IESP in 2026 to give the industry something it never had: real, structured education from someone who's actually done the job — not theory, not fluff, but the exact systems that work on the ground.
IESP organizes its training around three learning paths, so you can jump in wherever you are:
- Foundations — for new and aspiring operators who need to learn the business from the ground up.
- Professional Development — for established companies refining their craft or working through the things that aren't quite clicking.
- Business Scaling — for owners ready to grow revenue, hire, and build a company that runs without burning them out.
The training: Estate Sale Project Management
IESP's flagship live course is Estate Sale Project Management ($199) — eight modules with six months of access that walk you through an entire sale from the first client call to the final payout. It tackles the exact things operators struggle with: pricing with confidence, writing contracts that protect you and the family, staging a home so it sells, running a smooth sale day, and handling the money side professionally. More courses are on the way as IESP expands its curriculum.
The credential: Certified Estate Sale Fiduciary™ (CESF)

Trust is everything in this business. Families hand you the keys to a loved one's home, their heirlooms, and their finances — and they need to know you'll honor that. The Certified Estate Sale Fiduciary™ (CESF) certification ($149) is your proof. Over six months of access, it trains you in ethics, fiduciary duty, handling client funds the right way, confidentiality, documentation, and risk management. Earn it, and the designation is valid for 24 months — and you get to display the CESF badge on your website, your marketing, your email signature, and your EstateSaleFinder profile.
That badge isn't decoration. It tells every grieving family who's interviewing companies that *you take this responsibility seriously.* In an industry that's largely unlicensed and unregulated, a real credential is one of the fastest ways to win trust and the job.
