5 Open Source Tools I'm Using For My Business In 2024
Almost every business today is hooked on pricey apps for basic operations, but what if you could get the same functionality without the hefty price tag and data

Almost every business needs these five tools:
- Team Communication (Slack, $8.75/month/user)
- Project Management (Trello, $6/month/user)
- Invoicing (FreshBooks, $24/month)
- Shared Inbox (HelpScout, $20/month/user)
- Sales Pipeline (Pipedrive, $50/month/user)
Not only are these apps expensive, they remove your data from your control. For example, as Austen Allred (BloomTech CEO) found out, it would cost $78K just to export his company data off of Slack.
This is completely unnecessary. These tools are now commodities, and there are dozens if not hundreds of viable replacements. Many of them are available nearly for free if you bring your own hosting.
Here are the replacements for these apps that I'm utilizing for my team in 2024.
Mattermost (Slack Alternative)
I was excited for 37Signals & Once.com to unveil their first product, but when they did... and it was Campfire... I was underwhelmed.
Yes, Slack is an overpriced and not as great these days. But we already have an amazing alternative and it's free.
Enter Mattermost. Mattermost is everything I want from a Slack style tool. The UI is great. When you visit the Mattermost site, you might get turned off. Their site is pretty terrible. This is common for open source tools.
Despite being billed as 'for technical teams', I've thrown VAs from the Philippines into our Mattermost with a simple link to sign up and no one has struggled to operate the tool (from designers to assistants).
There are more tricks up Mattermost sleeve, as they also have a feature called Playbooks which is basically a bot that can walk your staff through an SOP. Totally amazing.
Focalboard (Trello Replacement)
Focalboard is actually available as a plug-in for Mattermost, and that's how we're using it at Client Amp, but you can self-host it as a standalone tool or even just run it as a desktop app.
In its most basic form, you can just leave it in Kanban board mode. But much like Notion or Airtable, there are alternative views like lists (spreadsheet) and calendars.
Invoice Ninja
If you're sending out quotes or invoices, you could just use Stripe, but they're going to force you to upgrade and you'll end up paying even more in fees.
Did you know that if you're using Stripe for subscriptions, they charge you more per transaction than a regular transaction? Madness.
Invoice Ninja is wonderful. It has a desktop and mobile app (if those are your thing) or you can use it on the web. We chose to white label Invoice Ninja as it's only $30 a year, but otherwise the app is totally free to self host.
FreeScout (HelpScout Alternative)
A shared inbox or helpdesk is critical if you are a team of more than one. FreeScout is a very mature platform. The core tool is totally free, and they have paid add-ons that you can choose to pimp out your installation with features that make sense to your business.
I ended up spending about $130 on modules for our Client Amp FreeScout instance. This allowed us to add features like canned replies, a web-based front-end for client submissions, and satisfaction ratings.
It's running perfectly and our clients love being able to email us support tasks vs. having to log-in to a portal.

EspoCRM (Pipedrive Alternative)
Using a dedicated sales pipeline can transform how you manage leads. As we know, what gets measured gets managed, and if you're dealing with prospects via your email inbox, chances are you aren't measuring much.
EspoCRM is a wonderful alternative to the sea of expensive (and difficult to manage) SaaS Sales CRMs. As with all of the apps in this list, it is completely free to get started. You may have to use some of their paid add-ons to get everything you need, like Gmail support or automations. We use regular SMTP for email and don't need to automate just yet, so we aren't paying a dime.
Not Just About Money
We're running all of these tools on a single server. Nothing is being hit by tons of traffic at once, so everything is lightening fast. This is undoubtedly saving us hundreds of dollars a month. For a bigger team it could easily be in the tens of thousands.
But it's not just about the money. It's about the fact that our data is ours and we aren't being held hostage by a SaaS provider. We have backups on different providers so we don't have to be worried about losing access to some of the most valuable data in our company.
This is just the tip of the iceberg for why I'm going deep into FOSS (Free & Open Source Software) in 2024.
What Is Most Interesting To You?
Give me your feedback on this list. Which ones would you like to add to your business? Which ones did I miss that you're already using?
I plan to create training material around many of these tools, because I think they are under utilized. Your feedback helps me decide where to devote my time.
And, as I mentioned before, I'm also available to set it up and manage software like this for you. Just hit reply for details.
