Software Stack for Marketing Agency

Hi everyone,

I am running a small online marketing agency and I am looking to upgrade some things. I've been looking at different products, comparing reviews and searching for deals on Appsumo.

I was just wondering what kind of software stack everyone else is using, especially those who are also running an agency.

For example, estimate/invoice software, CRM, any streamline processes, etc.

Thanks in advance!

you can get cheap lifetime deals if you camp around appsumo, pitchground etc frequently... I got most of my stuffs there and managed to snag some very good products there. Sometimes stacksocial also have very good deals for VPNs and password managers. Would be also interested in what other people use for running their agencies.
