How to Choose a CRM for Your Business: A Brief That Prevents Costly Mistakes
Vendors offer dozens of off-the-shelf CRM systems. Any one of them can turn out to be useless for your business if you don't ask the right questions before you choose.
A CRM is usually chosen for years. Implementation takes time, the team gets used to working in it, and data piles up. That's why a wrong choice is expensive: a subscription you pay for but don't use, integrations that have to be rebuilt and leads that get lost along the way. The tool that prevents this is a brief — a structured requirements document you hand to a vendor or developer.
In this guide we'll explain:
- what a CRM is and which problems it solves;
- what types of CRM systems exist and in what order to implement them;
- why you need a brief before you choose;
- how to write a CRM brief, step by step;
- which integrations to check and which mistakes to avoid.
What a CRM is and why you need one
The term CRM (Customer Relationship Management) is like an umbrella brand: under one name it groups together very different technology solutions.
In one form or another, a CRM exists in almost every business. As soon as you have customers (in B2C) or business partners (in B2B), you need to keep track of your relationship with them: what the customer was interested in, what stage the deal is at, what they've already bought and how much. Building a database like that isn't hard at all. At worst, you keep it in Excel.
That solves the basic CRM task. A database like that can help customer service, but the technology has come a long way since. Today a CRM is a system that doesn't just collect information about customers but also lets you act on it: add a customer to a personal or general promotion, enroll them in a loyalty program, award points for purchases and let them redeem those points in store or online.
In that sense, a CRM is a complex technology system, and the people who implement it are developers and integrators, not marketers. But if the choice isn't based on marketing and sales requirements, the result can be disastrous. More than once, companies have bought an expensive system without a clear list of requirements, and in the end nobody used it. That's why it's important to understand what a CRM is made of.

What problems a CRM solves in marketing and sales
Broadly speaking, a CRM has one strategic task: retaining customers. It does this in two ways:
- it improves the product based on customers' real needs;
- it helps allocate the business's resources so that the most profitable customers remain the core of the business.
In the first case, the information that builds up in the CRM about contacts and deals lets you analyze what's happening with the product and what needs improving. The same information turns customer service into a predictable, managed process: every request is logged, and every reply and deadline gets a reminder.
The second way is a loyalty program. Loyalty is a mutual trade-off: the customer gives the business money and time, and the business gives up part of its profit by offering discounts or special service to certain customers. The problem is that if you give perks to everyone, there's no profit left.
In a competitive market you can't be the best quality, the cheapest and the fastest all at once. Customer loyalty isn't predictable either: some customers will move to competitors, and that's normal. What you can do is keep your most profitable customers with special terms, preferences and discounts. This is where a CRM plays an irreplaceable role: it helps you allocate perks correctly.
Small and mid-sized businesses often have an even more urgent task: not losing leads. Inquiries come in from the website, Facebook, Instagram and WhatsApp, and each one needs to reach a rep, move through the sales stages and get timely follow-up. A CRM organizes all of this into a single sales pipeline.
Types of CRM systems
CRM systems can be divided into three types:
- systems that collect and store customer information and run automated loyalty program scenarios;
- systems that analyze that information, segment customers by attributes and predict their behavior;
- systems that manage marketing communication with customers automatically.
Operational CRM
Most CRM systems on the market belong to the first type. They centralize customer information for your team. Choosing a system like this is easier, because the requirements come down mainly to a convenient, clear interface.
The system gets more expensive and complex when it doesn't just collect information but also runs marketing scenarios for specific customers. For example, when you want customers themselves to use the system: update their details in a personal account on your website or app, or activate a loyalty card that syncs their purchases in store and online.
Analytical CRM
The second type only loosely counts as CRM. These are systems for automating data analysis, and they have little in common with operational systems.
An analytical system groups the information the operational system has collected, matches marketing promotions to each customer segment, estimates their effect and predicts customer behavior. There are far fewer vendors of systems like these, and for years the field was dominated mainly by large global companies such as SAP, SAS and IBM.
Customer communication management systems
The third type, sometimes called a marketing automation platform, combines the capabilities of the previous two. To understand how it works, imagine using all the systems together. The operational CRM stores up-to-date data and loyalty program scenarios. The analytical CRM segments the database and calculates the effect of each scenario. The communication system orchestrates both: it takes segments from the analytical system and promotions from the operational system, and sends each customer the right message. For example, a weekly WhatsApp message to a specific customer segment as part of a loyalty program scenario.
In what order to implement them
These types are implemented one after another. Without an operational CRM it's hard to build up complete customer data, so it's essential at the start. Don't implement an analytical system before you understand what customer segments you have and what to do with the information. In the meantime, you can replace it with manual calculations in a spreadsheet or SQL queries — for example, the RFM segmentation we explained in our guide to end-to-end analytics.

Why you need a brief before choosing a CRM
If the basic task — collecting information about customers and deals — can be handled with simple tools, when do you need a structured list of requirements?
A CRM's complexity is determined by the marketing mechanisms it can run. It's not just a nice interface that displays customer data, but a system every bit as complicated as a bank's payment processing system.
At first glance, a system that gives a discount based on order value doesn't seem more complicated than one that records deposits and withdrawals. But it's harder to build than it looks, because the same promotion can be implemented in different ways for different audiences.
That's exactly what a brief is made of: a description of the marketing mechanisms your business needs. It's important to be as specific as possible. A CRM that can give 10% off orders over $100 can't necessarily give a discount on a specific product. If you don't put details like these in the brief, the vendor may deliver a system completely different from what you expected.
Because of competition, CRM vendors turn solutions they built for specific clients into standard products. That's why the market has a huge variety of architectures, capabilities and prices. What fits a B2B company with dozens of clients that needs to organize its processes perfectly won't fit a B2C company building a loyalty program for hundreds of thousands of members at all.
The bottom line: there's no universal CRM, and the choice should be based solely on your business's needs. Well-known systems like monday CRM, HubSpot, Salesforce, Zoho or Pipedrive are very different from one another, and the system's name matters less than how well it fits your brief.
How to write a CRM brief: step by step
Step 1: Define the tasks
First, define the tasks the system will perform automatically. A task can be:
- an action the customer or rep triggers, such as joining the loyalty program through a form on your website;
- a fixed or variable loyalty program rule, triggered manually or automatically when a certain threshold is reached. For example, a discount on a third item when you buy two;
- a feature of the system itself, such as daily data backups or different permissions for reps and managers.
Step 2: Group them into categories
Tasks are usually grouped into categories that match the system's capabilities:
- lead capture and data collection;
- deal and sales stage management;
- tasks, reminders and follow-up;
- customer communication: email, SMS and WhatsApp;
- loyalty program, points and perks;
- automations and scenarios;
- reports and dashboards;
- permissions, backup and data security;
- integrations with other systems.
Here's what a detailed category looks like — for example, "Loyalty program sign-up and data collection": sign-up at the checkout, through the call center, on a paper form, in the website's personal account, in the app, via a web form, by SMS and by email; consent to receive SMS and emails; custom fields in different formats (text, date, phone, email); card replacement through the call center or website; and a mechanism that detects and merges duplicates.
Step 3: Prioritize and write in detail
You must prioritize tasks and describe them in detail. Prioritizing helps you and the vendor choose the best configuration in terms of capabilities and budget. Precise wording prevents a game of "broken telephone."
For example, "discount support" is a vague requirement. "Discounts on individual products and product groups, with variable discount amounts depending on the time and day of the week" is a requirement that describes exactly what the system needs to do.
Step 4: Leave room for the vendor to respond
A brief doesn't have to be a closed list of requirements. It's better to let the vendor tell you what the system can and can't do. To do that, add a few columns to each line of the brief for the vendor to fill in:
- the capability exists in the system;
- it doesn't exist, but can be developed;
- it doesn't exist and can't be developed;
- development cost;
- development time.
You'll use these columns at the end to compare several vendors' proposals and choose the right configuration.
Step 5: Talk to the vendor's existing clients
The most effective step in the selection — and a good sign of vendor quality — is a call with, or a visit to, businesses already working with a similar configuration of the system. If the vendor agrees to connect you with existing clients, that's a sign they're confident in what they're selling. It's hard to hide problems in a conversation like that, especially if you know what to ask.

Integrations to check before you choose
A CRM doesn't work on its own. It's only worth something when it's connected to the places where your customers and money are. Before choosing a system, check that it connects to all of these:
- Your website and forms. An inquiry from your website should enter the system immediately, along with its traffic source and UTM parameters. Without that, you can't tell which ad brought in the deal.
- WhatsApp. In many markets a large share of inquiries arrive via WhatsApp. Check whether the system connects to the WhatsApp Business Platform and whether you can connect a chatbot that qualifies inquiries.
- Lead ads. Leads from Facebook, Instagram and Google ads should go straight into the system, with no manual copying.
- Telephony. Logging inbound and outbound calls, ideally with recording and linking to the contact.
- Invoicing and payments. A connection to your invoicing system and payment pages, so a closed deal is also updated on the financial side.
- Calendar and meetings. Scheduling meetings from within the system and syncing with Google Calendar or Outlook.
- Language support. An interface and message templates in your customers' languages, and correct right-to-left support if you work with RTL languages — including in SMS and email.
- API and webhooks. Even if there's no built-in connector, an open API lets you connect almost any system using Make, Zapier or n8n.
- Privacy and data security. A customer database is subject to data protection laws such as the GDPR. Check where the data is stored, how permissions are managed and how backups work.

Common mistakes when choosing a CRM
Choosing based on a pretty interface or what a competitor uses
A convenient interface matters, but it won't help if the system can't run the mechanisms your business needs. And a system that works great for a competitor won't necessarily fit your processes.
Writing generic requirements
"We need automations" and "we need reports" are requirements every vendor will answer "yes" to. Only a detailed requirement shows what the system can really do.
Implementing everything at once
Trying to launch sales, service, a loyalty program and automations on day one usually ends in confusion and a team that goes back to Excel. It's better to start with the most important process and add stages gradually.
Not involving the people who'll use the system
If your sales and service reps weren't involved in the choice, there's a good chance they won't use the system. Involve them in writing the brief and reviewing the demo.
Not checking data export and migration from the old system
Check upfront how contacts and history will be moved into the new system, and how duplicates will be merged. Also check how to export your data if you ever want to switch to another system.

Choosing a CRM: frequently asked questions
What's the best CRM for a small business?
There's no single best system for everyone. Small businesses usually start with cloud systems like monday CRM, HubSpot or Pipedrive, but the choice should be based on your brief: which processes matter to you, which integrations you need and how many users will work in the system.
Can I just use Excel?
At first, yes. Once several people are handling leads, inquiries are coming in from multiple channels and follow-ups start slipping through the cracks, it's time to move to a CRM.
How much does a CRM cost?
Cloud systems are usually sold as a monthly per-user subscription, and some have a free basic tier. On top of that come implementation, integration and training costs. Custom development of complex mechanisms, such as a loyalty program, is a separate project with its own pricing.
How long does CRM implementation take?
A simple system with a sales pipeline and a connection to your website forms can be up and running within a few days to a few weeks. A system with a loyalty program, automations and many integrations is a project of several months.
What's the difference between a CRM and a marketing automation system?
An operational CRM stores information about customers and deals and manages the sales process. A marketing automation system uses that information to send each customer segment the right message at the right time. Many systems today combine both capabilities.
