The Essential Software in Your Business’s Technology Stack


Different businesses require different, industry-specific tools. A barber shop isn’t going to need real estate software for instance. But what we are going to cover here are the core applications that all businesses need. Let’s get started…

The high-level view of your tech stack can be broken down into these 5 broad categories:

  • Communication
  • Collaboration
  • Marketing
  • Accounting
  • Operations

We will now dive deeper into each one:


Your employees need to be able to communicate with each other: sometimes in real-time and sometimes asynchronous. You have various mediums such as video, audio, and textual. 


Email is the most widely used communication tool for businesses. E-mail is not designed for fast discussions or decisions, it is your asynchronous form of communication with internal or external stakeholders.

Team Messaging

This is your real-time one-to-one and one-to-many form of communication. Team messaging is one of the primary means of communication for your businesses, allowing information, ideas, files and more to be sent and received in real time.

Video Conferencing

Video conferencing allows your team to communicate from almost anywhere–from home, office or workplace–to all devices. Screen sharing, screen recording, and video streaming capabilities that can facilitate virtual meetings remotely.


Collaborative tools and software drive your business. Particularly for small, remote-teamed companies. New collaboration software enables teams to work faster anywhere.

Project Management

The main goal of project management software is to track collaboration and optimize productivity. Small companies rely on project management tools and resources to ensure that teams have a healthy workload and complete tasks on time.

Knowledgeable and Note-taking Software

These tools ensure that your team is fully engaged on the same page in the end. Digital note-taking apps work across a wide range of digital formats and are the most resourceful way to keep all relevant information together and useful. Add messages or emails to your party, or switch to tasks or backups.

Document and File Management and Storage

Data management and file-sharing systems are essential for small business and team collaboration. File sharing software supports and syncs all of your important files and documents in the cloud across all of your devices–all while maintaining file records that are unique and shared across your company. Backup software keeps your data safe from unforeseen events and protects you from data loss.


Your employees need to be able to schedule appointments and meetings both internally and externally with clients and prospects.


Nobody is going to buy your product or service if they don’t even know it exists. Marketing is essential to every business and so is marketing software.

Customer Relationship Management (CRM)

CRM applications and services manage all of the company’s contact points with current and potential clients, and more.

Social Media Marketing

Social media marketing software is usually used for tracking, controlling, analyzing and automating your social media presence and interactions on Facebook, Twitter, Instagram, and other social media platforms.

Email Marketing

Email marketing systems are used for the production and coordination of product and service advertising campaigns. Marketing teams also use these resources to maintain customer relationships. Email Marketing offers a wide range of digital marketing tools and complements social media and content marketing strategies.


Every business needs accounting software. Period. Accounting software keeps track of the money going in and out of your company.


Money is the lifeblood of your company and you need a tool to track and manage it.  Track income and expenses, profit and losses.  Maintain your financial records throughout the year, helping you to foresee and prevent critical errors and problems in the future.

Payment Processing

Your business needs to be able to process payments from customers right? You need to be able to accept credit cards, Paypal, and any other forms of payment.


You need tools to manage the complex components that make up the system that is your business. 

Customer Service

A Helpdesk is a key business tool for handling and monitoring customer service requests using real-time reporting and response times. Some of the current customer service software solutions include a ticketing system or a chatbot to streamline contact and process management workflows to solve problems.

Electronic Signature

Legal documents, including contracts and formal business applications with your clients, partners, and vendors require signatures.

Human Resource

Your business is made up of employees and you need tools to hire, fire, train and manage them. Human resource software lets you track performance, help direct corporate decision-making from mental health to career creation and compensation. Performance reviews build clear expectations and steer workers in the right direction by providing feedback on individual, team and company-wide goals. Education and investment in employee development and growth are also essential.


So we covered the fundamental building blocks of your business technology stack. It was more of a high-level, broad overview. In later articles, we will be doing more of a deep dive into the specifics. Stay tuned…
