The 2025 Agency Tech Stack: How You Can Replace 5+ Tools With HighLevel

Marketers are only utilizing 42% of their martech stack capabilities.

This underutilization is attributed to overlapping tools, talent shortages, and the complexity of the martech ecosystem.

In 2025, agencies are recognizing that such complexity hinders scalability and efficiency. Clients demand faster turnarounds, personalized campaigns, and real-time follow-up. A fragmented tech stack with multiple logins and disconnected data impedes even the most skilled teams.

To address this, agencies are consolidating their tools. HighLevel CRM has emerged as the go-to all-in-one CRM for agencies, integrating sales, support, and automation into a single platform.

Let's explore how HighLevel can streamline your agency's operations.

Why Agencies Are Ditching Fragmented Tools for Unified Platforms

Running a modern agency means managing a long list of systems: ClickFunnels, Calendly, Mailchimp, Twilio, HubSpot, Zapier… the list goes on!

The more tools you add, the more you:

• Pay in monthly subscriptions.

• Lose time switching between dashboards.

• Miss leads due to gaps in automation.

• Create reporting headaches across platforms.

What agencies want in 2025 is simple: fewer tools, more automation, better insights, and one central place to run everything.

That’s exactly what HighLevel CRM delivers: a single, scalable, AI-powered platform that handles funnels, email, SMS, appointment booking, pipelines, reviews, and AI tools for agencies without needing five different logins or a full-time Zapier expert.

Tool 1: Funnel Builder (Goodbye ClickFunnels or Leadpages)

Building landing pages, lead magnets, and opt-in funnels used to require specialized software like ClickFunnels or Leadpages, as well as hours of copywriting.

HighLevel includes a powerful funnel builder for agencies that:

• Uses Funnel AI to generate pages instantly based on prompts.

• Includes drag-and-drop builders for full design control.

• Embeds forms, calendars, and dynamic content with ease.

• Offers A/B testing and analytics out of the box.

Most importantly, all funnels live inside your CRM, so every click, form, and conversion ties back to a contact’s record automatically.

Result? Faster launches, better tracking, and no more duct-taping ClickFunnels to your CRM or Zapier.

Tool 2: Email & SMS Marketing (Replace Mailchimp, Klaviyo, Twilio)

Email, SMS, and voice outreach are core to client retention and lead nurturing. But juggling Mailchimp for email, Twilio for SMS, and another system for voice drops is both expensive and inefficient.

HighLevel unifies all messaging channels:

• Create multi-step email/SMS campaigns with Workflow AI Assistant.

• Personalize messages using contact tags and behavior triggers.

• Use Content AI to write emails or SMS with the right tone and purpose.

• Send ringless voicemails and dynamic replies — all from one place.

Unlike platforms like Mailchimp or Klaviyo, HighLevel is built for sales and marketing automation tools to work together, not separately.

Tool 3: Appointment Scheduling (No More Calendly or Acuity)

Calendly is great, to be fair. 

That is, until your agency outgrows the free plan and you’re paying per user just to let clients book time.

HighLevel includes a full appointment scheduling system that:

• Offers custom calendar links for your team or clients.

• Embeds in landing pages or websites.

• Connects directly to workflows for automatic confirmations, reminders, and follow-ups.

• Integrates with your Google or Outlook calendar to avoid conflicts.

Plus, you can use 24/7 AI sales agents to book calls automatically through live chat, SMS, or phone.

This turns your calendar into an engine for conversions, not just a place to find a time slot.

Tool 4: Pipeline & Lead Management (Replace HubSpot or Pipedrive)

Managing leads across a pipeline is crucial. But HubSpot’s CRM gets expensive fast, and tools like Pipedrive often lack integrated marketing automation.

HighLevel gives you:

• A visual drag-and-drop pipeline view.

• Lead scoring, tasks, and reminders.

• Contact activity timelines with email, SMS, call, and form data.

• Native integrations with forms, funnels, and conversations.

• CRM with AI Features like auto-tagging, AI summaries, and smart filters.

You can set up separate pipelines for different services or teams, all within a single platform.

This is what makes HighLevel a standout marketing platform for agencies that need visibility and control across the entire sales journey.

Tool 5: AI Agents & Automation (Ditch Zapier & Third-Party Bots)

One of the biggest headaches for agencies is stitching together automation with third-party tools like Zapier, ManyChat, or Make.

HighLevel includes:

• Voice AI that answers and handles calls around the clock.

• Conversation AI for SMS, chat, Facebook, and Instagram DMs.

• Workflow AI Assistant to guide your automations visually.

• Reviews AI to respond to Google and Facebook reviews in your tone.

• Ask AI inside your dashboard to help you build anything, anytime.

These are not widgets. They are AI tools for agencies that turn your CRM into an intelligent system that helps you follow up, qualify, and close leads faster, without needing another tool or plugin.

Bonus: White-Label SaaS Mode for Scaling Revenue

Most CRMs are designed to support your agency. HighLevel goes further by giving you tools to monetize it.

You can:

• White-label the platform under your own brand.

• Offer client logins and automate deliverables.

• Mark up AI Employee access as a revenue stream.

• Launch full client portals with pre-built snapshots and systems.

It’s more than a tool. It’s a business model in a box, and the key reason why HighLevel tops so many HighLevel reviews from agencies who have scaled from client work into SaaS resellers.
