5 SaaS Tools Every Small Business Should Know in 2025
You don't need an IT department — you need the right tools.
When you start a business, you do everything yourself. You invoice in Excel, send emails from Gmail, and your "logistics system" is a sticky note on your desk. That works for a while. Then it doesn't.
The good news is that today there are software-as-a-service (SaaS) tools that solve real problems at a reasonable monthly cost. These aren't big-company luxuries — they're necessities for any small business that wants to scale without falling apart.
What Is SaaS and Why Should You Care?
SaaS means you pay a monthly subscription to use cloud-based software. You don't install anything, you don't maintain servers, you don't need a sysadmin. If the service doesn't work for you, you cancel and move on.
The beauty of it is that you get access to technology that only large companies could afford before. And you pay proportionally to your size.
The 5 Tools I Recommend
-
Electronic Invoicing — In Chile, issuing electronic tax documents (DTE) is mandatory. Tools like Bsale or Haulmer connect you directly to the Chilean tax authority (SII) without you having to deal with the XML behind it.
-
Shipping Management — If you sell online and ship orders, you need something better than copy-pasting tracking numbers. Despacha centralizes your shipments with multiple carriers in one place.
-
Email Marketing — Mailchimp, Brevo, or Klaviyo. It doesn't matter which one you pick — what matters is that you stop sending emails one by one. Automate welcome sequences, abandoned carts, and promotions.
-
Cloud Accounting — Nubox, Buk, or Fintoc. Keeping your books up to date isn't optional, and doing it in spreadsheets is a ticking time bomb.
-
Project Management — Notion, Trello, or Linear. If you work with a team (even just two people), you need a place where tasks live. Not in WhatsApp.
How Much Does All of This Cost?
Most of these tools have plans starting from $5 to $20 USD per month. Some have free tiers to get started. The total cost can be less than what you spend on a team lunch.
The most expensive mistake isn't paying for tools — it's wasting time doing manually what software solves in seconds.
The important thing is not to try to implement everything at once. Start with your biggest pain point (usually invoicing or logistics) and add tools as you grow.
