Is a Chamber of Commerce or Business Group Worth Joining?
A business group pays off when you attend regularly, meet owners who share your customers and count what comes from it; the dues are the smaller cost, and a short test tells you whether a group fits.
A chamber of commerce or business group is usually worth joining if you can attend at least monthly, if its members serve the same customers you do at nearby moments and if you track the referrals and partnerships it produces for a year. The strongest evidence comes from a randomized experiment in the Quarterly Journal of Economics, in which firms whose managers met in small groups every month for a year increased revenue by 8.1% compared with firms that did not meet, and regular meetings produced more partnerships than one-time ones.
Six questions to ask before you join
| Question | A good sign | A warning sign |
|---|---|---|
| Who are the members? | Owners whose customers overlap with yours, such as agents, trades, salons and practices | Mostly large employers, banks and vendors selling to members |
| How often does it meet? | A recurring small-group or industry meeting each month | One large mixer a quarter |
| What do members get besides events? | A directory listing, referral introductions, a newsletter that reaches local residents | A plaque and a logo for your window |
| What does a year cost in money and hours? | Dues and time you can name, below the value of a few new regular customers | Dues plus required sponsorships and paid event tickets |
| Can you visit first? | One or two free guest visits | Payment before you see a meeting |
| Will you show up? | A meeting time that fits your slowest hours | A time you would have to close or lose bookings to attend |
A one-year break-even test
| Annual dues (Assumption) | $500 |
|---|---|
| Hours a month at meetings (Assumption) | 2 |
| Value of an owner hour (Assumption) | $50 |
| Cost of time per year (Calculated (2 × 12 × $50)) | $1,200 |
| Total annual cost (Calculated ($500 + $1,200)) | $1,700 |
| Annual spend of a regular customer (Assumption) | $600 |
| New regulars needed to break even (Calculated ($1,700 ÷ $600)) | 2.8, about 3 |
Illustrative example; replace every assumption with your own numbers.
Add a line for the group to your "How did you hear about us?" question on the day you join, and look at the count at month six and month twelve. If a group has not produced the break-even number of customers or one working partnership by then, try a smaller group, such as an industry association, a neighborhood business association or a referral circle that meets weekly, before giving up on groups altogether.
Free options are worth trying first. Small Business Development Centers and SCORE mentors offer advising at no cost through the SBA, and some neighborhood business associations charge modest dues, so compare a few before paying for the largest.
Why it works
The experiment randomly assigned about 2,800 young firms either to small groups of managers who met monthly for a year or to no meetings, so the 8.1% revenue gain reflects the meetings themselves rather than the kind of owner who likes to join groups. The firms also gained business partners, and the researchers found that regular meetings created more partnerships than one-time meetings did, which is why attendance matters more than membership.
