I was a member about 2 years ago, was a member for 2-3 years.
The leads were interesting, some were just pure fiction, the person had no interest at all in what you did, and was passed just because they needed a referral.
Others were repeat referrals... as in, a customer ordered a reprint, so they'd pass another referral, yet it was originally passed, and should have only required a thank you for the business card. No biggie, except if members see you receiving handfuls of referrals each week, they assume you're doing OK and there's no need to find you one.
The business passed figure is stretching the imagination, if you've 3 members of 10+ years, they're still putting TYFTB cards in for recurring work from year 1. It's not actual turnover for the year, so when they say this year we've passed £1m between us, it actually isn't, some of that is years old.
We got mostly internal referrals, it was OK when we started out, but we wanted to grow our customer base, and get external leads. We got very few, so seemed pointless paying to renew, we kept some of the members as customers.
All the traffic light systems, and statistics, I couldn't care less about... it's about making money. Getting roped into committee, or visitor host roles, it all took too much time, for very little reward.
Same with them organising stacker days, sending letters inviting people, then follow up calls... I'd have been much better doing it for my own business... the only guaranteed winner in BNI is the person you're paying your money to.
Yes it has it's benefits, but if you join, keep you mind on your own business, and you own ROI.
