The Best Software Stack for a Small Business (2026)

The right SMB software stack costs $300–$800/month total and pays for itself by month two. Here's what we'd put on the company card today.

The default stack

• Payroll: Gusto for the US, Deel for global contractors.
• CRM: HubSpot Free until you have a sales motion, then Pipedrive or Attio.
• Accounting: QuickBooks if you work with a US accountant, Xero otherwise.
• Marketing: Customer.io for product-led, ActiveCampaign for service businesses.
• Project mgmt: Linear for product, Asana for cross-functional ops.

How to decide what to buy

Run every tool through the SaaS ROI Calculator. If payback is under 6 months, buy it. Between 6–12, consider it. Over 12 — pass unless it's strategic.
