I credit bullet journaling with changing my entire life. Whether you follow that particular system or not, a journal is the first and least expensive tool to help find your focus -- in business or in life.
Essentialism by Greg McKeown really makes you ask what is important to you and why, and then encourages you to set boundaries and start saying No to everything else.
My Current Week Trello Board keeps me on task with my predetermined priorities. Planning this out before the start of each week gets me centered and feeling in control.
Trello is hands-down my favorite organizational/productivity tool (I even helped beta-test it!). It is also what I use to document all my business SOPs, oversee delegated work, AND it's free!
I use David Allen's Getting Things Done system but it's important to make sure you've thought through your Focus first so you're getting the right things done, not just #allthethings.
Calendly is a simple calendar scheduling tool makes me smile every time I get a new appointment email and realize I completely bypassed all that back-and-forth about does this time work or this day etc.
MailerLite is the email service I use for my coaching business. They are free for up to 1,000 subscribers and include automation workflows.
I used Constant Contact for 15+ years for my bookstore before switching to MailerLite. ABA members can get a rebate back each year on one month's fees.
Zoom is the primary way I deliver my coaching services as it's so important to be able to put a face to the voice and see the 55% of communication encoded in body language.
Before you work on your business finances, make sure your personal ones are in order. There are many, many systems out there. Find the one that works for you. For me it was All Your Worth.
YNAB (You Need a Budget) is my favorite budgeting app, especially if your bank and credit cards sync. I can charge things to credit cards to get cash back yet it's just as easy to check the app to see if you can afford something as it would be to check your wallet (or envelopes) in a cash-based system. Win-win.
Profit First by Mike Michalowicz is the best business budgeting system I've come across and what I am implementing in both my businesses.
