What is the best hardware or software to use when making cold calls to companies?

[Talkst]

Hello there! I am planning to make some cold calls to businesses and I am seeking advice on what products have been proven to sell well. While there are plenty of items I could potentially sell, I am interested in something that has a high chance of success. For instance, basic office supplies like regular pens and paper may not be the best option. I am looking for products that can offer a solution to a problem or a need that the business may not be aware of, or something that can improve upon what they currently use. Any suggestions would be greatly appreciated. If you have experience with cold calling businesses and know of a product that consistently sells well, please do share!

Items that are primarily service rather than material. As long as your work aids their company in some way, it doesn't matter if it's design, advertising, or administration-related.
For instance:
Rebranding an established eatery's logo
Managing Google Ads for a Publishing Firm
Hourly administrative work for a flourishing financial institution.
