You don't need a $500/month software stack to launch a business. Every tool below is genuinely free — not a 14-day trial, not a "free with asterisk" plan that locks core features. These are real tools used by real startups that charge $0 until you outgrow them.
This guide covers the complete startup toolkit: accounting, CRM, design, website, email marketing, project management, and payments. Each category names the best free option, what it includes, and when you'll realistically need to upgrade.

Accounting & Invoicing
Best free option: Wave
Unlimited invoicing, receipt scanning, double-entry accounting, and financial reports. No user limits. No monthly cap. Genuinely free — Wave monetizes through payment processing (2.9% + 30¢ per card transaction) and optional payroll ($20/month).
Also worth considering: Zoho Invoice (5 clients free, better templates), GnuCash (desktop-only, full accounting, open source), Akaunting (self-hosted, unlimited everything if you have a server).
When to upgrade: When you need payroll, inventory tracking, or your accountant asks for QuickBooks-compatible files. Typically at $3K–$5K/month revenue.
CRM & Sales Tracking
Best free option: HubSpot CRM
Up to 1,000,000 contacts (yes, really). Deal pipelines, email tracking, meeting scheduling, live chat widget, and a basic reporting dashboard. Free forever — HubSpot makes money when you upgrade to Marketing Hub or Sales Hub ($20+/month).
Also worth considering: Bigin by Zoho (pipeline-first, simpler than HubSpot, free for 1 user), Folk (relationship-focused, good for services), Notion (DIY CRM with templates — no automation but fully customizable).
When to upgrade: When you need automated email sequences, custom reporting, or more than 5 email templates. Usually around 50+ active leads per month.
Design & Brand
Best free option: Canva
Logo maker, social media posts, business cards, flyers, presentations, and video editing. 250,000+ free templates. The free tier is generous enough that most small businesses never need to upgrade. Canva Pro ($13/month) adds background remover, brand kit, and premium stock photos.
Also worth considering: Figma (free for 3 projects — better for web/app design), Photopea (free Photoshop alternative in the browser), GIMP (desktop, powerful but steep learning curve), Unsplash/Pexels (free stock photos, no attribution required).
Website & Online Presence
Best free option: Carrd (single-page) or WordPress.com (multi-page)
Carrd builds a clean one-page site in under an hour — free with a carrd.co subdomain. WordPress.com free tier gives you a blog-style site with basic customization. For a proper multi-page business site, Google Sites is surprisingly capable and completely free with a Google account.
Also worth considering: Google Business Profile (free "website" within Google Search — essential for local businesses regardless of your main site), Notion (publishable pages with notion.site subdomain), Linktree (link-in-bio page for social-first businesses).
When to upgrade: When you need a custom domain ($10–$15/year for the domain, then $4–$12/month for hosting) or e-commerce features. A custom domain builds credibility — worth the investment once you're earning.
Email Marketing
Best free option: Brevo (formerly Sendinblue)
300 emails/day (about 9,000/month) with unlimited contacts. Includes automation workflows, signup forms, and transactional emails. Brevo's free tier is more generous than Mailchimp's current free plan, which dropped to 500 contacts and 1,000 sends/month in 2023.
Also worth considering: MailerLite (1,000 subscribers, 12,000 emails/month free — better templates), Mailchimp (500 contacts free — still good for very small lists), Buttondown (100 subscribers free — best for simple newsletters).
Project Management & Productivity
Best free option: Notion
Unlimited pages, databases, kanban boards, calendars, and wikis for individual use. Notion is both a project management tool and a knowledge base — one tool replacing Trello + Google Docs + Evernote. The free plan limits block storage for teams but is unrestricted for personal use.
Also worth considering: Trello (unlimited boards, 10 boards per workspace — simpler, pure kanban), Asana (15 users free, great for task assignments), ClickUp (100MB storage free — most features of any free PM tool), Google Tasks (dead simple, built into Gmail).
Communication & Meetings
Best free option: Google Workspace (personal) + Zoom
Gmail, Google Meet (60-minute group calls), Google Drive (15GB), Docs, Sheets, and Calendar — all free with a Google account. For longer meetings or webinars, Zoom free tier gives 40-minute group meetings with 100 participants. Between the two, you have email, video calls, file storage, and scheduling covered.
Also worth considering: Slack (free for small teams — 90-day message history), Discord (unlimited history, originally for gaming but increasingly used by businesses), Calendly (1 event type free — essential for service businesses that book appointments).
Payment Processing
Best option: Square (in-person) + Stripe (online)
Neither is technically "free" — both charge per transaction (Square: 2.6% + 10¢, Stripe: 2.9% + 30¢). But there's no monthly fee, no setup cost, and no minimum. You pay only when you earn. Square includes a free POS app and ships a free card reader. Stripe handles online payments, subscriptions, and invoicing.
Also worth considering: PayPal (3.49% + 49¢ — higher fees but more buyer trust for new businesses), Venmo for Business (1.9% + 10¢ — good for casual/local services), Cash App for Business (2.75% — simplest setup).
Legal & Compliance
Free resources you should know about
The IRS EIN application is free at irs.gov (ignore paid services charging $50–$100 for the same form). Most states let you register a business name and file an LLC online — fees vary ($40–$500) but the filing portals are free to use. SCORE.org offers free business mentoring from retired executives.
Free legal document tools: Termly (free privacy policy and terms of service generators), HelloSign (3 documents/month free for contracts), SBA.gov (free business plan templates and local resource directories).
For more on formation costs: LLC Costs by State and Business License Costs.
Social Media Management
Best free option: Buffer
3 social channels, 10 scheduled posts per channel, and basic analytics. Enough for a startup managing Instagram, Facebook, and one other platform. The interface is the simplest in the category — no learning curve.
Also worth considering: Later (5 posts/month per profile free — better for visual planning), Hootsuite (limited free — 2 accounts, 5 scheduled posts), Meta Business Suite (free, unlimited — but only for Facebook/Instagram).
The Complete $0 Startup Stack
Here's the full toolkit combined — ten tools that cover everything a new business needs:
| Category | Tool | Free Limit | First Paid Tier |
|---|---|---|---|
| Accounting | Wave | Unlimited | Payroll $20/mo |
| CRM | HubSpot | 1M contacts | $20/mo |
| Design | Canva | 250K templates | $13/mo |
| Website | Carrd | 3 sites | $9/yr |
| Brevo | 300/day | $9/mo | |
| Project mgmt | Notion | Unlimited (solo) | $10/mo |
| Communication | Google + Zoom | 15GB / 40min | $7/mo |
| Payments | Square | 2.6% + 10¢/tx | Pay-per-use |
| Legal | IRS + SBA | Fully free | n/a |
| Social media | Buffer | 3 channels | $6/mo |
Total monthly cost: $0. Total annual cost: $0. You'll pay transaction fees when you process payments (2.6–2.9% per sale) — but that only happens when money comes in.
The first tool most startups upgrade is accounting — usually 6–12 months in when revenue justifies the $15–$20/month for QuickBooks or Xero. Everything else stays free longer than you'd expect.
