Day 35 - lowkey continuing where I left off I've built a feature where you can not only generate and send invoices, but also receive them (via a dedicated email for utility bills or anything else). You can review them, mark them as paid, and view attached PDF invoices. Does this sound useful?

Day 34 of building I got burnt out trying to document my journey here on X while also building a reputation on Reddit and PH, working a full-time job, and raising small children. Realistically, I should focus on one thing at a time.

Day 33 of building in public My plan to cold call restaurant businesses went pretty well 🍺 Planned to call 1 businesses Called 3 2 Were interested, need to follow up by end of week to show a demo. 2/3 warm lead, not too bad :/ Are these good stats? (might consider changing the topic to cold calling/marketing in public)

Day 31 of building Starting fresh from next week, taking it slow for the next week, as I don't want to burn out. Plan for Invoxio.app launch on ProductHunt (0$ MRR) Plan for my restaurant business, do a single cold call, even though I hate doing them. (70$ MRR currently)

@bymarcoperez Thanks man, I think It will take far longer than I originally thought, with a full time job the focus is hard to achieve, but the vision is there

Day 30 of building Invoxio My original goal of 30 days of building in public is nearing. I was interesting, it took some energy to get used to sharing thoghts in public. Gone from 0 - 100 followers, I can probably do a lot better if I continue. Hard to focus on just one project Invoxio - figure out how to reach customers Digital Menu business - relies on cold calling (cold calling and demoing), but is sort of profitable atm.

Before I quit freelancing I was trying to get a few of my bigger clients on a retainer so that I could have a more stable income, but it backfired and most of them dropped eventually, and I couldn't really balance that many of them.. Still I feel that for me it would be better if I build a single product I could focus on, rather than many projects.
