Best Free Tools for Freelancers and Side Hustlers

When you’re starting a freelance business or side hustle, spending $100+/month on software tools before you’ve earned $100/month is a bad trade. The good news is that most of what you need in the early stages is available for free, and genuinely good enough to run a professional, client-ready operation.

Here’s what to use and why.

Invoicing and Getting Paid: Wave

Wave is the best free invoicing tool for freelancers and small business owners. You can create professional invoices, track which ones are paid or overdue, and accept credit card or bank transfer payments. The invoicing, accounting, and receipt scanning are completely free. Payment processing fees apply only when clients pay by card (2.9% + $0.60 per transaction for credit cards, 1% for bank transfers).

Wave also handles basic bookkeeping automatically: income and expenses are tracked, categorized, and can be exported for tax preparation. For most freelancers, it eliminates the need for a separate accounting tool entirely.

Contracts: Docusign or HelloSign (free tier)

Always have a signed contract before starting work. Both Docusign and HelloSign (now Dropbox Sign) offer limited free plans that allow you to send a handful of documents for electronic signature each month.

For simple freelance contracts, the free tiers are usually sufficient. Alternatively, AND.CO (now Fiverr Workspace) includes contracts, proposals, and invoicing in a free plan, a good all-in-one option if you want everything in one place.

Free contract templates for freelancers: Bonsai, NOLO, and the Freelancers Union all offer starter templates you can customize without a lawyer.

Client Communication: Notion or Google Workspace

Google Workspace (Gmail, Drive, Docs, Sheets, Meet) is free and handles most client communication and document needs for freelancers. A Gmail address at your domain (yourname@yourdomain.com) looks professional and costs nothing if you use Google’s free tier.

For keeping client projects organized, Notion’s free plan is excellent: create a client dashboard with project status, deadlines, deliverables, and notes. It’s flexible enough to serve as a lightweight CRM for tracking active and potential clients without paying for dedicated CRM software.

Project Management: Trello or ClickUp

Trello’s free plan gives you unlimited cards and up to 10 boards, more than enough for most freelancers managing 3 to 10 concurrent clients. Its visual Kanban-style boards make it easy to see what’s in progress, what’s blocked, and what’s done.

ClickUp’s free plan is more feature-rich (unlimited tasks, multiple views, time tracking) and suits freelancers who want more structure. The free tier is genuinely capable, ClickUp’s limitations on the free plan are primarily around advanced automation and storage, not core functionality.

Video Calls: Zoom or Google Meet

Both are free for most freelance use cases. Zoom’s free plan allows 40-minute meetings (unlimited with 1-on-1 calls). Google Meet is unlimited for 1-on-1 and up to 60 minutes for group calls with a Google account. For client discovery calls and project check-ins, either works fine without paying.

Design and Visual Content: Canva

Canva’s free plan covers most design needs for freelancers: social media graphics, presentation templates, simple logos, invoices, and content mockups. The free library includes thousands of templates across every format.

Canva Pro ($15/month) unlocks brand kits, background removal, and premium assets, worth it once you have consistent client work that requires branded materials. Until then, the free plan handles a lot.

Time Tracking: Toggl Track

Toggl Track’s free plan supports unlimited time tracking for up to 5 users. You can log time by client or project, and the reports show exactly how many hours you’ve spent on each account. Useful for hourly billing, for understanding if a fixed-rate project is profitable, and for tax documentation of business hours.

Password and Account Management: Bitwarden

Freelancers accumulate a lot of accounts: client platforms, software tools, social media accounts, ad accounts. Bitwarden is a completely free, open-source password manager that stores unlimited passwords and syncs across devices. More secure than reusing passwords or using browser-saved credentials, and genuinely free (not free-with-heavy-limitations like many competitors).

Proposals: Canva or Nusii Lite

For freelancers who need polished proposals, a well-designed Canva template handles the presentation layer. Add your scope, timeline, and pricing, export as PDF, and it looks as professional as anything generated by paid proposal software.

If you need an interactive web-based proposal with acceptance tracking, Nusii Lite and Proposify have free trials, useful to evaluate if you want to convert to paid tools later.

The Right Stack for a New Freelancer

Starting out: Wave (invoicing), a Google Workspace account (email + Drive), Trello (project management), Toggl (time tracking), and Canva (design). Total cost: $0/month.

That stack handles everything you need to run a professional freelance operation through your first $5,000 to $10,000 in revenue. Add paid tools only when a specific free tool is genuinely limiting your ability to work or win clients, which for most freelancers is later than they think.
