Sales rep at a small company doing mostly b2b sales

Hey everyone,

I am the only sales rep at a small company doing mostly b2b sales, both inside and outside sales. I have a huge list of prospects/clients that I keep on a google sheets, and it’s been working pretty well for me. However, I need to organize these prospects and clients better, because I do a lot of cold calls and it’s hard to keep track of everyone on google sheets.

What’s a good customer relation management solution that I can use, so that I can save time organizing my prospects and keep track of them better / more efficiently. If it helps- my company is considering for a long-term use and investment. We have already contacted a few of the https://www.mydock365.com/contract-management-system vendors after filtering from the numerous that we found on the internet. But, I’d like explore my options here.

I’m fairly new to sales , so any advice is appreciated!

Thanks in advance!
