1. How Does the Agency Learn Your Business Processes?
Why This Question Comes First
A good CRM or ERP system doesn't model generic processes. It models yours. An agency that jumps into development without understanding how your business runs is setting the project up to fail. Ask directly: what does your discovery phase look like?
The answer should include workshops with key stakeholders, workflow mapping, identifying pain points and a careful review of your current tools and integrations. If the agency's first move is a demo of an off-the-shelf product without a single question about your business, treat that as a red flag.
What to Look For
Does the agency ask about your business goals, not just technical requirements?
Do they assign a dedicated business analyst to your project?
Is the outcome of the discovery phase written down and approved before development starts?
2. What Technologies Do They Use, and Why?
The Tech Stack Shows How the Agency Thinks
Asking about technology isn't a pop quiz. It tests the agency's reasoning. Do they recommend a technology because it fits your problem, or because it's the one they know best? A strong partner can justify every technical choice in plain business language: "We chose this stack because it will scale with your transaction volume without a full rewrite when you triple in size."
Also check whether the proposed technologies are actively maintained by a healthy open-source community. This directly affects long-term security, performance and how easy it will be to find people to maintain your system.
Follow-Up Questions
Will this technology let us extend the system in 3 to 5 years without starting from scratch?
Who will be able to maintain the system after delivery: only you, or other vendors too?
How do you approach data security and compliance with regulations such as GDPR?
3. Who Will Actually Work on Your Project?
The Trap of the Senior in the Pitch and the Junior in the Project
One of the most common disappointments with IT agencies is finding out that the experts you met during the sales process have nothing to do with the delivery team. Ask directly: who exactly will be the project manager, the system architect and the lead developer on my project?
Ask for CVs or LinkedIn profiles of the key people. Ask whether you will have direct access to them throughout the project. A good boutique agency won't avoid this kind of openness. It will treat it as an advantage.
Warning Signs
The agency talks about "the team" without naming anyone
You can't speak with the future team lead before signing
High staff turnover or vague information about the team's experience
4. How Do They Manage the Project and Communicate?
Transparency Is the Foundation
Building a CRM or ERP system typically takes 3 to 12 months. Your business doesn't pause in that time, so you need an agency that acts as a real partner, not a black box. Ask about the method: Agile, Scrum, Kanban? How often are status meetings held? Where can you follow progress in real time?
According to PMI (Project Management Institute), projects run with agile methods have a 28% higher success rate than those managed in the traditional waterfall way. For you, that means regular chances to correct course and avoid expensive surprises at the end.
Signs of a Good Process
Sprint reviews with working demos: you see real software, not just status reports
A shared project management tool with live visibility of the backlog and task status
A single point of contact on the agency's side, so you don't chase several people for answers
Regular retrospectives, where the team looks back, adapts and improves
5. How Does the Agency Price Projects, and What Exactly Is Included?
Price Versus Value
Getting a quote for a CRM or ERP is one of the trickiest parts of choosing a vendor. Differences of 100 to 200% between proposals from different agencies are not unusual. A higher price doesn't always mean better quality, and a lower one isn't always a bargain. What matters is knowing precisely what you are paying for.
Ask for a detailed cost breakdown: how many hours go into analysis, design, development, testing and deployment? What is included and what costs extra (training, data migration, support after launch)? How does the agency handle scope changes during the project?
Engagement Models and What to Expect
Fixed Price works well for a clearly defined scope. The risk sits with the agency, but it can lead to corner-cutting if the project was underestimated.
Time & Material gives more flexibility and transparency, but needs mutual trust and solid communication.
A hybrid model puts discovery and design in T&M and development in Fixed Price. It is often the best balance.
6. What Experience Does the Agency Have in Your Industry or With Similar Processes?
Domain Knowledge Saves Time and Cuts Risk
An agency that has built systems for businesses with a similar model already knows the typical challenges and pitfalls of your industry. You don't have to explain what a sales pipeline looks like in a SaaS company or which reporting requirements matter in logistics. They bring that knowledge from day one.
Ask not only for case studies but also about the problems they ran into on similar projects and how they solved them. An honest talk about difficulties is a sign of maturity and professionalism.
Good Questions to Ask
Have you built systems for companies with a similar sales or operations structure?
What integration challenges do you usually meet in projects like this?
Which solutions worked best in your earlier CRM and ERP projects?
7. How Do They Handle Integrations With Your Existing Systems?
No System Lives in Isolation
CRM and ERP platforms rarely stand alone. In most companies they must talk to invoicing software, online shops, marketing tools, warehouse systems and the APIs of external partners. Integrations are often the most complex and costly part of an IT project.
Ask about the integration approach: do they have hands-on experience with the platforms you already use? What do they do when a third-party API is poorly documented or unreliable? Do they recommend a middleware layer or a data bus for more complex environments?
Companies that have integrated their business systems successfully report an average improvement in operational efficiency of 20 to 35%, but only when integrations are designed as part of the overall architecture from the start, not added later as an afterthought.
8. What Does Support After Launch Look Like, and on What Terms?
The Real Relationship Starts After Go-Live
Going live is not the end of the project. It is the start of the system's life inside your organization. Ask the agency directly: what happens after the official launch? What does the warranty cover? What is the SLA for critical bugs? Is there a support retainer, and what does it include?
A good agency treats support after launch as a long-term investment in the relationship, not a cost center. It should offer a support model that adapts to your needs, from basic monitoring and bug fixes to new features and modules.
Support Terms to Review
Response time for critical issues (for example, a maximum of 4 hours on business days)
Warranty scope: what is covered and for how long
Support pricing model (hourly, monthly retainer, bundled packages)
Escalation process for major incidents
9. How Do They Approach Testing and Code Quality?
Quality You Don't See, Until You Do
Testing is easy to gloss over when talking to an agency, and it is what hurts most six months after launch. Ask about the testing strategy: do they use unit tests, integration tests and end-to-end tests? Is there an automated CI/CD pipeline (Continuous Integration and Continuous Deployment)? How do they measure and report test coverage?
Companies that invest in test automation report up to 40% fewer production bugs and noticeably lower maintenance costs over time. An agency that takes testing seriously saves you stress and money later.
10. How Will the Agency Transfer Knowledge and Train Your Team?
A System Without a Trained Team Is Wasted Money
Even a very well designed CRM or ERP won't deliver its expected return if your employees don't know how to use it. Ask about the training plan: who delivers it, in what format (workshops, video recordings, written documentation) and how it is tailored to different user groups (sales team, management, IT).
Technical knowledge transfer to your internal IT team or a designated system administrator matters just as much. A good agency delivers documentation that lets your team handle basic configuration alone, without calling the vendor every time.
11. Who Owns the Code and the Data?
It's Your System, So Make Sure It Really Is
Too few clients ask this question, and overlooking it can have serious consequences. Who owns the source code when the project is complete? Do you have full access to the repository? What happens to your data if the cooperation ends?
Make sure the contract clearly states:
full transfer of intellectual property rights to you when the project is complete,
access to the Git repository throughout the project,
the right to export your data in a standard format at any time,
no vendor lock-in, meaning you can move to another IT partner without losing access to your system.
12. What Does Success Look Like, and How Will It Be Measured?
KPIs Instead of Promises
The last question, and perhaps the most important, is about measurable results. A strong agency shouldn't just talk about "delivering a system". It should help you define what success means for your business and how to measure it. Do you expect a 30% cut in customer service response time? A sales cycle cut in half? Ten hours less of manual reporting every week?
Setting KPIs (Key Performance Indicators) before the project starts does two things: it forces the agency to understand your business objectives, and it gives you an objective measure of whether the investment paid off.
Companies that track the ROI of their CRM and ERP projects usually report higher satisfaction with them, because they can put a number on the value instead of relying on gut feeling.
Your Checklist Before Signing
Choosing an agency to build your CRM or ERP is a strategic decision that will shape how your business works for years. No article replaces in-depth conversations with potential partners, but these 12 questions give you a solid framework for comparing every agency on equal terms.
Principles to keep in mind:
An agency that asks about your business before talking about technology is a partner, not just a vendor
Openness about the team, the process and the pricing should be the norm, not the exception
Support after launch and code ownership belong in the contract, not in the fine print
KPIs and success measures should be set before the project starts, not after it ends
The best technology is the one that solves your problem, not the one the agency knows best
If the agency gives clear, well-reasoned answers to 10 out of 12 questions, you have found a strong candidate. If things get vague around code ownership, team composition or success measures, treat that as a warning.
