3. Payments & Invoicing

You need to get paid quickly and easily, whether you’re selling a product, course, or service.

What works best:

  • Stripe – Simple checkout links, subscriptions, and invoicing.
  • PayPal – Still good for one-off payments, especially internationally.
  • Bonsai – Great for freelancers. Send contracts, invoices, and even track time.

Bonus: Use Revenued if you need fast funding for your business based on revenue, not credit score.

 

4. Content Creation

Your content builds trust. Whether it’s YouTube, Instagram, or TikTok, you’ll need tools to make short-form video and graphics that stop the scroll.

Easy tools for creators:

  • CapCut – Free mobile and desktop video editor with templates, subtitles, and TikTok-style effects.
  • Canva – Design anything in minutes: thumbnails, social posts, eBooks, pitch decks.
  • Descript – Record, edit, and caption podcasts or screen recordings like a doc.

 

Use ChatGPT to help you write captions, hooks, or even full scripts, then plug it into your visuals.

 

5. Scheduling & Productivity

Time is your most valuable asset. Use tools to plan your week, schedule posts, and stay on top of goals, especially if you’re doing this outside of your 9–5.

Top options:

  • Notion – All-in-one workspace. Plan content, track goals, and store business ideas.
  • Google Calendar – Simple but powerful for time-blocking and setting reminders.

Keep it simple. Start with one system and grow from there.

 

6. Communication & Support

As your business grows, so will your messages. Make it easy to connect with your audience and stay organized.

Recommended tools:

  • Tidio – Live chat and automated messages for your website. Great for answering FAQs fast.

 

  • Gmail + Google Workspace – Set up a custom business email (like yourname@yourdomain.com).
  • ManyChat – Build Instagram or Facebook DM automation to collect leads or answer common questions.

You don’t need a full team, just a smart setup.

 

7. File Storage & Sharing

You’ll need to share files with clients, store your designs, or back up your content.

Best bets:

  • Google Drive – Free, reliable, and easy to organize. Share folders or documents in one click.
  • Dropbox – Good for larger file transfers, especially for creatives or video editors.

Don’t underestimate how fast digital clutter can slow you down. Keep it organized from day one.

 

8. Learning & Skill Building

If you’re not improving, you’re falling behind. The best online business owners are always learning, from other creators, communities, and platforms.

Best places to grow:

  • YouTube – Free tutorials for every skill: marketing, SEO, ads, branding, and more.
  • Podcasts – Search for shows on entrepreneurship, side hustles, and digital marketing.
  • Skool groups – Join paid communities with live calls, resources, and accountability.
  • Udemy / Coursera – Cheap courses to learn new platforms or tools fast.

Invest time in skill-building. It compounds just like money.

 

9. Bonus: Automation & AI

The secret weapon in 2025 is automation. Tools that save you time by handling repetitive tasks or helping you get more done with less.

Use these:

  • Zapier – Automate tasks between apps (ex: new customer → add to email list).
  • ChatGPT – Brainstorm ideas, write scripts, generate content outlines, or handle customer support responses.
  • Loom – Record videos to explain ideas, onboard freelancers, or send personal replies to clients.

Even with a small side hustle, automation can help you scale.
