Which is more effective when trying to sell B2B services; Cold calls,cold emails, or onsite visit to clients office?

I've found that a working demo will filter out users who are just curious. The only inquires I get are clients that are genuinely interested in proceeding.

My experience shows that onsite visits are more likely to close the sale. When you are through email, they can't sense your tone of voice or excitement about the sale. When on the phone, they can't see your expressions or body language, which is most of what's communicated. If you can't do onsite, then do a video call.

For me, it would really depend on the product.

Cold calling folks for a low touch, low priced B2B product is not the approach (in most cases) unless you are doing customer research or trying to spin up a new product with some initial customers. That's usually reserved for high-priced products. The same extends out to onsite visits for me.

Maybe you could tell us a bit more about your product and it's pricing?

I'm assuming because you're talking about cold calls you're specifically trying to solve the top of the funnel problem. If you have networks, work your networks. Use LinkedIn and ask for intros. That's going to be the best for getting you your first customers. If you have a super niche industry and go to a small conference and can get a list in advance, cold emails and phone calls also won't be cold anymore. Read "New Sales. Simplified." and "Predictable Prospecting" -- if you do have to just call off a sheet, make sure to do you research in advance, give hyper-personalized emails, follow up with phone calls.

Hi Ibrahim, you can start creating a community around your product.

Initially, it doesn't matter if your product is getting sold or not, however, you can join with people who can spread about your product and can create a brand awareness channel.

This way you can create brand awareness for a long-term.

I have been using community channels like slack, LinkedIn (along with aeroleads.com) etc. and created own pool of people who share the insight about our product and services.

I think emails would work best, at least it would give them time to consider and thoroughly read your offer. If you call someone when they are busy they'll quickly dismiss it like "Oh, Google Forms is good enough for us" and will have a negative opinion of your brand.

It depends.

What are you trying to sell? To whom? And at what price?

How far along are you? Do you already know exactly what problem your product solves for your customers? Do you have paying customers already?
