Here we go B2B!

Right, that's definitely an advantage for you, so make sure to leverage it then.

How I would go about it will be something like this. Also as a remark this is usually hard work, but I can tell you if you stick to it long enough, you will get your opportunities.

1. First, must understand why they need to change the ERP, or to get your ERP system. So pretty much what problem you are solving.
2. Then, come up with a list of companies that are doing this service, if you could start on your region or country the better. Then get their information, at least email, and if you feel confident over the phone get their phone number too. You can find some of this info though their sites, or using email scrappers for LinkedIn and websites like hunter.io
3. Once you have a list of potential candidates, I will come up with an outreach strategy combining cold mail, in mail (LinkedIn) and phone calls, and even better go to visit them if possible. The strategy have to have no less than 5 touchpoints.
4. Once you have the strategy ready, then come up with a compiling copy, being nice, but stating that if they don't choose your solution, they will still suffering the Pain.
5. Make sure to keep up with the cadence you decide for the sequence, and keep contacting them, if you run out of leads in your country then move to the next one.

As stadted above this will take some time, but keep it up and eventually you will get infant of the right customer.

Also a remark, do not try to sell them on the outreach campaign, just make sure they give you a chance to have a meeting to discuss your solution. On that meeting you can discuss details and aim for the next steps like closing.

Let me know if any other question!
