CRM Requirements Document: What to Include Before You Talk to a Developer

Large IT projects typically go over budget by 45% and miss deadlines by 7%. In the case of CRM development, this often happens due to not careful CRM requirements gathering. So, instead of overpaying for fixing architectural errors and making constant changes, it is important to create a clear and detailed requirements document from the start.

Why "We Need a CRM" Isn't a Requirement

Saying something like "we need a convenient CRM for sales" often leads to IT project failures. If founders ask software developers for help without understanding what needs to be optimized with a new system, they face these common CRM project risks:

Inflated estimates.

Due to CRM scoping mistakes from the client’s side, contractors give wide budget and timeline ranges that usually end up growing even more.

Extrapolation.

Developers guess what is missing and use their own assumptions, which often do not match company's actual business processes.

Too expensive change requests.

New features often come up in the middle of the project, turning into urgent changes that require overtime.

Wishlists instead of requirements.

‍Employees often give vague requirements of what they want, which is different from a real requirements document where every item is justified both economically and operationally.

For example, a Swiss car brand with a branch in Luxembourg asked us to digitize their dealership processes. Because they did not have a unified system, they had to manage catalogs manually. We turned their request into a custom, multilingual CRM platform that automated workflows and created digital brochures. Sixteen dealerships started using it in the first month. This experience helped us avoid common architectural issues and deliver an effective solution for a complex industry.

We also developed a custom CRM for a network of 16 Harley-Davidson dealerships in Switzerland.

We had to manage several challenges, including supporting four languages, defining dealership rights, and handling large amounts of technical data. Without clear technical specifications at the start, the project could have become chaotic. However, we built a solid architecture that let us automate interactive brochure creation and scale the system for both the US and German markets.

These examples show that developing a successful CRM starts with digitizing existing business problems, like manual catalog management or the need for multilingual support for a dealer network. Thorough analysis of operational challenges and clear requirements from the beginning set the rules for building the architecture and influence the project's success.

1. Document Your Current Process, Not Just the Desired One

To perform a CRM discovery, start with workflow documentation, even if these workflows rely on manual operations. Here’s how you can do it:

• Perform a current state process mapping by describing each step in the sales cycle, starting with the first interaction with the customer and ending with post-sales service;
• Conduct an audit of different data sources, review where all customer information is stored;
• Make a list of roles and access rights, recording which employees are involved at each stage, what data they enter, and what information they need to see to complete their tasks.

2. Define the Entities and the Relationships Between Them

If you are unsure about which objects the system should track and how they connect, the developers will use a standard CRM data model. To avoid this, you should define the following:

• Business objects: decide what exactly the system should record (leads, accounts, companies, deals, support tickets, physical assets, contracts or shipments);
• Relationship architecture: define how these objects interact with each other (relationships are one-to-many or many-to-many);
• Niche specifics: identify any unique industry entities that out-of-the-box CRMs don't cover in enough detail.

Here’s a custom CRM checklist to help make CRM entity mapping easier:

• Main entities (leads, contacts, companies, deals);

• Financial objects (invoices, payments, deal-closing documents);

• Operational objects (tasks, projects, tickets);

• Custom CRM objects (equipment, contracts, logistics points);

• Relationship types and restrictions (cascade delete, required fields).

3. Specify Roles, Permissions, and Who Sees What

When you separate permissions, you help protect your trade secrets and make your employees’ jobs easier. Start by defining access levels so developers can take into account all role-based access CRM requirements. Here’s how:

• Set different permissions for regular sales managers, department heads, system administrators, external partners, franchisees, and others;
• Describe CRM data visibility restrictions, such as whether managers should only see their own deals or if regional teams can have access to information from other branches;
• Specify audit rules for CRM roles and permissions so that the system could record every action, including status changes or database exports.

4. List Every System the CRM Must Integrate With

A CRM on its own does not provide much value, so you need to compile a list of CRM integrations – programs with which it needs to connect with. Most often, these are email services, calendars, marketing tools, ERP and accounting systems, online stores, and technical support tools. You also need to decide on the following:

• The direction of data flow: whether it is a one-way transfer (like sending leads) or a two-way exchange (updating statuses);
• Technical limitations: this refers to the availability of a ready-made API for third-party system sync and the presence of old systems in your list, as this expands the list of CRM API requirements.

Why does this matter? We began building a Swiss HR platform using WordPress. As the client's business expanded, we ran into the limits of this setup. Moving to Laravel and Vue.js, adding AI features, and automating tasks helped the platform grow the client base by 182% and increase interviews by 900%. 

If the client had considered future growth from the start, these architectural features could have been taken into account right away. 

5. Set Reporting and Data Requirements Upfront

Reports are essential for making good management decisions. Explain CRM reporting requirements, including:

• CRM analytics needs: what metrics should senior management review, like funnel conversion, sales plans, or employee performance, and how often should these be reported;
• CRM data compliance: personal data storage requirements, export rules, and meeting industry or regional standards.

6. Clarify Non-Functional Requirements Most Teams Forget

Platform stability relies on more than just standard features:

• CRM scalability requirements include database size and the number of users who can access the system at the same time, both right after launch and in the following 1-2 years;
• Accessibility and CRM data migration cover uptime requirements, moving old database tables, mobile/offline access, and other CRM non-functional requirements. 

Next, we will look more closely at both functional and non-functional requirements.

What a Developer Actually Needs From You to Give an Accurate Estimate

A clear and detailed brief helps your contractor give an accurate development estimate. This means that if you include all entities, roles, integrations, and non-functional requirements, the cost range will be predictable, and help developers meet deadlines. 

On the other hand, skipping the CRM project scoping stage can cause:

• Scope creep, where new details are added to the project while coding is already underway;
• Unplanned business processes or conflicts with integration software identified only during the development discovery phase;
• Higher editing costs because of architectural mistakes discovered  in the middle of the project.

Final Thoughts

If you take the time to clearly describe your workflow and data models before building a CRM, you can lower your project costs and avoid repeated changes. A trusted technology partner, rather than a group of freelancers, can help you improve your plans and turn them into a reliable solution.
