Making The Most of Your Plumbing Trade Show and Conference Experience

Build your wish-list

Before you go, make sure you create your list of key questions you're facing right now in your business, industry, or team. These can be your talking points while meeting with peers or during Q&A time at the end of speaker presentations. It can also help keep you focused in the exhibitor area, knowing who you should spend your time talking to.

Is there a conference app?

Find out if there is a conference app. Download it before you see the latest announcements and potential peers, mentors you can meet up with. The best relationships are built outside the Plumbing conference. Find out where the after parties and peer dinner groups are meeting. WiFi is not always a sure thing at the venue.  Make sure you download the app before you go.

Get your Twitter account ready

A lot of the conference chatter happens via a Twitter hashtag thread. Find out what the conference hashtag will be, and save it in your search preferences in your Twitter mobile app. Engage. These events are much better when you can share what you've learned, insights, and tips with other plumbing professionals. Great way to see who else is attending and who you may want to follow on Twitter for post-event conversations and networking.

Block out time for meetings

The relationships you make will be better than the presenter's message (sorry speakers! I know you agree, though :) ). Find time in the conference schedule to have one-on-one coffee connections or lunch meetings. Get to know other professionals. So many people take the time to build support groups or masterminds with other Plumbing professionals. Allows them to have a trusted community of contacts to share ideas and grow alongside.

Take advantage of the early-bird sessions

The more well-known speakers are scheduled during the meat & potatoes time slots of the conference.  However, some of my favorite sessions during professional conferences have happened during the pre-conference time slots. The 'up and comers' are speaking and put a TON into their presentations. Don't overlook the newbies to the speaking scene.

Set a Goal and Strategy

Before you visit any event, remember why you're taking time out of your valuable schedule to attend. You have probably already had to answer this question once before deciding to register but take the time to identify the purpose.

  • Out of all the trade shows, why did you choose to attend this one?
  • What is the primary objective you want to achieve at this plumbing expo?

Having a clear plan will help you stay focused, and you will save time and money.

Most business owners attend trade shows because they have pain points that need to be solved. From the time you register until the conference day, you will want to keep specific notes of what pain points you are looking to ease.

It's good to look at all the different exhibitors at the conference to get a head start on finding business solutions. When you list the vendors you want to visit, make sure you write down the exact place they will be at the show so you don't waste time looking for them up and down the aisles.

Set Up Meeting Before the Conference

If you took the time to identify the pain points of your business, it should be reasonably easy to locate some vendors where you can set up meetings beforehand. It is always better to have one-on-one meetings, and you can guarantee this goal by setting up meetings before the expo. Trade shows are always full of distractions, and it's hard to lock someone down if you haven't done it before the expo.

Balance Your Time

There are three ways to spend time at a trade show:

  • Seeking out vendors on your list.
  • Attending seminars and info sessions.
  • Wandering to see what you discover.

Identify and target the sessions or speakers you must see and schedule them in your itinerary first. It's always a good idea to visit the vendors on the second day if you want to get some quality time with them. The first day of any trade show is crazy, but if you want to make sure you get freebies, you may want to give the floor a gander.

Reconnect

It is always fun to visit and meet with vendors and associates to cultivate ongoing relationships. Take some time to meet with other business colleagues to find out what they have been doing to resolve some common pain points.

A small conversation can yield significant results and potentially save you valuable time and money. Even though you are there for business intentions, plumbing trade shows are an exceptional place to network. Social events are ideal for collecting recommendations and learning more about the people within the plumbing industry.
