A Complete Sales Tool Stack for Under $100/Month

You don't need a sales team's budget to run a sales process

When I first started selling on my own, I assumed I needed whatever tools the big sales teams used. Then I looked at the price tags and realized most of that software is built for teams of twenty, not a team of one.

The good news: you can put together a sales tool stack under 100 dollars a month that covers everything you actually need. Not a stripped-down version either. A setup that handles your pipeline, your emails, your calendar, your meeting notes, and your writing, without you manually stitching things together at 9pm.

Here's how I'd build it category by category, with a free option and a paid option for each.

1. CRM: where your deals actually live

If you're tracking leads in a notebook or a messy spreadsheet, this is the first thing to fix. A CRM doesn't need to be complicated. It just needs to tell you who you're talking to, what stage they're at, and what happens next.

• Free pick: HubSpot's free CRM tier. It covers contacts, basic deal tracking, and email logging. It gets clunky once you want automation or more views, but for someone just starting out, it's a real CRM at no cost. If you're weighing this against paid tools, our Ungrind vs HubSpot comparison breaks down where the free tier stops being enough.
• Paid pick: Ungrind, starting at $29/month. It's built specifically for solopreneurs and freelancers rather than sales teams, and the pipeline updates itself after calls instead of you typing notes in after the fact. There's a 30-day free trial and no credit card required to start.

The difference between free and paid CRMs usually comes down to how much manual upkeep you're willing to do. Free tiers work fine if you enjoy data entry. If you'd rather spend that time talking to prospects, a paid tool earns its keep fast.

2. Email: writing and sending without losing track

Your inbox is probably already doing double duty as a sales tool, whether you meant it to or not. The question is whether you're tracking opens, using templates, or just retyping the same pitch every week.

• Free pick: Gmail with basic templates (Canned Responses in settings) and follow-up reminders. It's not fancy, but it's free and it works if your volume is low.
• Paid pick: Google Workspace, which starts cheap per user and gives you a professional email address, more storage, and better calendar integration than a personal Gmail account. It's less about "sales features" and more about looking legitimate when a prospect checks who they're emailing.

You don't need a dedicated sales engagement platform at this budget. Save that spend for later once your email volume actually justifies it.

3. Calendar and scheduling: stop the back-and-forth

Nothing kills momentum with a prospect like five emails just to find a meeting time. This is one of the easiest wins in your whole stack.

• Free pick: Google Calendar's built-in appointment scheduling (Appointment Schedule feature). You set your availability, share a link, and people book directly. No separate account needed if you're already on Google Calendar.
• Paid pick: Calendly's paid tier, if you need multiple event types, reminders, or integrations beyond what Google offers. Check their website for current pricing since it varies by plan.

Honestly, most solopreneurs can stay on the free option here indefinitely. Save the paid upgrade for when you're running multiple types of calls (discovery, demo, onboarding) and need separate booking pages for each.

4. Meeting recorder: because you can't sell and take notes at the same time

This is the category people skip and then regret. Trying to run a good sales conversation while typing notes means you're doing both badly. You either miss what the prospect said or you miss the chance to actually listen and respond.

• Free pick: Google Meet's built-in recording (available on some Workspace plans) or just recording yourself with your laptop's screen recorder and reviewing it later. It's manual and you'll spend time re-watching calls, but it costs nothing extra.
• Paid pick: Ungrind's meeting bot joins your Google Meet or Microsoft Teams calls automatically, transcribes the conversation, and updates your CRM pipeline based on what was said. It also creates follow-up tasks and a summary after the call, so you're not the one writing recap notes at 6pm. Zoom and Outlook support are coming soon.

This is the one place I'd actually recommend spending money over staying free. The time you get back from not manually transcribing or summarizing calls adds up, and the follow-up tasks mean fewer leads quietly going cold because you forgot to send that one email.

5. Writing assistant: for proposals, follow-ups, and the emails you keep putting off

Every solo seller has that one email that sits in drafts for three days because you can't find the right tone. A writing assistant won't replace your voice, but it helps you get past the blank page.

• Free pick: ChatGPT's free tier. Good enough for drafting follow-up emails, tightening up a proposal, or rewording something that sounds too stiff.
• Paid pick: ChatGPT Plus or Claude Pro, both of which run in the range of $20/month. Worth it if you're writing proposals, long-form content, or need longer context windows for bigger documents.

Treat this as an editor, not a ghostwriter. The best use is taking your rough draft and asking it to tighten the structure, not asking it to invent your pitch from scratch.

Putting the sales tool stack under $100 together

Here's what a realistic month looks like if you mix free and paid smartly:

• CRM (Ungrind): $29/month
• Email (Google Workspace): roughly $6-12/month depending on plan
• Calendar: free (Google Calendar)
• Meeting recorder: included with Ungrind
• Writing assistant: $20/month (ChatGPT Plus)

That lands you somewhere around $55-60 a month for a stack that used to require separate tools costing far more when bought individually as "sales enablement" software. Even if you went fully paid on every category, you'd still land comfortably within a sales tool stack under 100 dollars.

If you want to go entirely free first, that's a reasonable starting point too. Use HubSpot's free CRM, Gmail, Google Calendar scheduling, manual call recording, and free ChatGPT. It'll cost you time instead of money, which might be the right trade when you're just testing whether your offer works at all.

A few things worth knowing before you commit

Free tiers often have limits that aren't obvious until you hit them, like contact caps or losing access to automation. Read the fine print before you build your whole process around a free plan, or you'll be migrating data mid-quarter.

Also worth noting: some CRMs and meeting tools handle recording and data storage differently depending on where their servers are located. Ungrind, for example, is GDPR compliant with data stored on EU servers in Frankfurt, and it's operated by Cowrite AB out of Stockholm. If data residency matters to your clients (this comes up a lot with European B2B buyers), it's worth checking where any tool you're considering actually stores information. This isn't legal advice, just something to factor in and confirm with your own due diligence if compliance is a hard requirement for your business.

When to upgrade from free to paid

A good rule of thumb: upgrade the tool that's costing you the most time first, not the one that looks the most impressive. For most solopreneurs, that's the meeting recorder and CRM combo, since manually updating a pipeline after every call is the task most likely to get skipped when you're busy.

If you're deciding between CRMs specifically, it's worth comparing a couple of options side by side rather than picking based on brand recognition. We put together an Ungrind vs Pipedrive comparison if you're weighing that decision, and there's more on general setup over on the Ungrind blog.

You don't need every tool on day one. Start with a CRM and a calendar link, and add the meeting recorder once you notice you're losing track of what was said on calls. Add a writing assistant once you're sending enough emails that drafting them feels like a bottleneck.

Try it before you commit to anything

If you want to see how the CRM and meeting recorder work together instead of piecing together five separate tools, you can start a 30-day free trial of Ungrind with no credit card required. Head to the Ungrind homepage to get set up in a few minutes.
