Every small business ends up needing roughly the same stack of software eventually: something to track projects, something to track customers, something to send email, a way to get paid, a way to store files safely, and a way to keep passwords from becoming a liability. This directory covers the major categories one at a time, with the same approach as our AI tools directory: honest tradeoffs over hype, and a clear sense of who each recommendation actually fits.
How we picked these tools
The same three criteria from our AI tools directory apply here: active, mainstream adoption rather than obscure niche software; a genuinely usable free tier or trial wherever one exists; and a clear sense of who each tool is actually built for, since business software in particular tends to scale badly in either direction, a solo freelancer drowning in enterprise features, or a growing team stuck on a tool built for one person.
Project management
Tools like Asana, Trello, and ClickUp organize tasks, deadlines, and team coordination, replacing the shared spreadsheet or group chat that inevitably breaks down once a team passes a handful of people. The right pick depends heavily on how your team actually thinks about work: visually, in boards; hierarchically, in lists and subtasks; or around specific deadlines and timelines. Read our full guide to best project management software for the specific differences.
Customer relationship management (CRM)
A CRM replaces tracking customers and leads in a spreadsheet once that spreadsheet stops being enough, which happens sooner than most new businesses expect. Options like HubSpot, Salesforce, and Pipedrive range from genuinely free entry points to full enterprise sales platforms. Our full guide to best CRM software for small business covers where to actually start.
Email marketing
Despite social media’s dominance, email remains one of the highest-return channels for reaching customers directly, and tools like Mailchimp, ConvertKit, and ActiveCampaign handle the list management, automation, and deliverability concerns that make email marketing actually work at scale rather than looking like spam. See our guide to best email marketing software for the specific differences between them.
Website builders
No-code website builders like Wix, Squarespace, and Webflow let a business get a professional-looking site live without hiring a developer, though they differ significantly in how much design flexibility they trade for ease of use. Our guide to best website builders breaks down which fits which kind of site.
Accounting software
QuickBooks, FreshBooks, and Wave cover invoicing, expense tracking, and tax preparation for freelancers and small businesses, at a fraction of the cost of a dedicated bookkeeper for straightforward cases. Our guide to best accounting software covers which fits a true solo freelancer versus a business with employees and more complex books.
Password managers
A password manager is one of the highest-leverage, lowest-effort security upgrades available to anyone, individual or business, generating and storing unique, strong passwords instead of reusing the same few across every account. Tools like 1Password and Bitwarden differ mainly in convenience features and whether you want an open-source option. See our guide to best password managers for the full comparison.
Cloud storage and backup
Google Drive, Dropbox, and dedicated backup services like Backblaze solve two related but distinct problems: everyday file access and sharing, and true disaster-recovery backup in case a device is lost, stolen, or destroyed. Our guide to best cloud storage and backup services explains why you may genuinely need both.
E-commerce platforms
Shopify, WooCommerce, and BigCommerce power the large majority of online stores, and picking between them mainly comes down to how much technical control you want versus how much you want handled for you. Our guide to best e-commerce platforms compares them directly for a business actually trying to sell online.

The pattern across every category on this list
Nearly every category above follows the same underlying shape: a genuinely free or low-cost entry point built for individuals or very small teams, a mid-tier built for a growing small business, and an enterprise tier built for large organizations with dedicated administrators and budgets. Reading past the marketing on any specific tool’s pricing page to figure out which of those three tiers a product actually targets tells you more about fit than most feature comparisons do. A small business evaluating Salesforce against HubSpot’s free CRM, for instance, is really comparing an enterprise tool against a tool built specifically for the tier that business is actually in.
Integration matters more than any single tool’s feature list
Business software rarely operates in isolation; a CRM that doesn’t connect cleanly to your email marketing tool, or an accounting platform that can’t talk to your e-commerce store, creates manual, error-prone busywork moving data between systems by hand. Before committing to a tool in any category, check its actual integration options with tools you already use or plan to adopt in adjacent categories, this is often a bigger practical factor in day-to-day friction than any single feature within one tool.
How we’ll keep this directory updated
Business software categories move slower than the AI tools covered elsewhere on this site, feature sets and pricing shift, but the fundamental tradeoffs between, say, Shopify’s managed convenience and WooCommerce’s self-hosted flexibility, tend to hold for years rather than months. That said, specific pricing and feature details in the guides linked throughout this page should be treated as a snapshot at the time of writing rather than a permanent, unchanging fact, always confirm current pricing and features directly on a tool’s site before committing.
How to prioritize if you can only add one tool right now
If budget or bandwidth only allows adopting one new tool at a time, prioritize whichever category is causing actual, felt pain today, missed follow-ups because customer tracking lives in someone’s memory, invoices going out late because there’s no system, rather than the category that seems most “professional” to have in place. A password manager is the one near-universal exception: it’s low-effort to adopt, has essentially no downside, and meaningfully reduces real security risk regardless of what else is going on in the business.
A note on switching costs
Business software is stickier than personal tools once real data lives inside it, customer records in a CRM, a year of transactions in accounting software, a live website’s content in a builder. Migrating later is possible but rarely trivial, so it’s worth spending a bit more time evaluating fit before committing to a tool for anything that will accumulate significant data over time, even if that means a slower start.
Frequently asked questions
Do I need all of these categories from day one?
No. Most solo businesses start with just accounting software and maybe a simple website, adding a CRM, email marketing, and formal project management as the business and team actually grow into needing them.
Are free tiers of business software actually usable, or just trials?
It varies by category and is called out specifically in each guide linked above. Several categories, notably CRM and cloud storage, have genuinely permanent free tiers; others, like most website builders and e-commerce platforms, are closer to a trial that requires payment for a real, publicly usable result.
Should a very small business use enterprise-grade software?
Generally no. Enterprise tools carry complexity, and often cost, that a small team won’t use and will actively find frustrating. Each guide in this directory specifically calls out which tools scale down well to small-team use versus which are built primarily for larger organizations.
