GreenHouse Interior：正確的權限分配，讓企業運營更順暢、更安全

Mr. Nguyễn Hoàng Long (38 tuổi) – founder of GreenHouse Interior, a small interior design and construction company in Ho Chi Minh City – once believed that “giving everyone authority would be faster.” But after three years of operation, he realized that it was precisely this approach that slowed down his business.

Each employee had access to all customer data, projects, and quotes. A single accidental action could delete contract information. Once, a marketing employee mistakenly deleted a project landing page worth hundreds of millions, causing an advertising campaign to be halted mid-way. “As the team grew, I realized I couldn’t rely on trust – I needed a control system,” Mr. Long shared.

When Access Control Becomes a Matter of Survival

At GreenHouse, each interior design project typically involved three teams: marketing responsible for finding clients, sales for consulting and quoting, and technical staff for implementation. However, because everyone worked on a shared file, no one knew who was editing or deleting what. “One person would adjust material prices without others knowing, leading to incorrect quotes sent to clients. Each such mistake cost us our reputation,” he recounted.

Moreover, without permission levels, new employees could still access old customer data, copy lists, and take them elsewhere. GreenHouse began to lose internal trust – and that’s when Mr. Long turned to GTG CRM.

Solution: Access Level Control – Clear Roles, Clear Responsibilities

Immediately after implementation, GTG CRM helped Mr. Long restructure the entire permission system within the company.

He chose three default permission groups:

• Administrator for himself and the department heads, with full system access.
• Marketing Manager for the marketing department, allowed only to create and edit campaigns, landing pages, and posts.
• Sales Staff for the sales team, allowed only to view and update contacts, unable to edit marketing data.

After that, Mr. Long used Custom Roles to further refine permissions for each individual. For example, the design team leader only had permission to view customer information for projects they were responsible for; customer service staff were only allowed to send emails and respond to messages, unable to view quotes.

“Initially, I feared that strict permission settings would slow down work,” he shared. “But the reality was the complete opposite. When everyone did only their part, processing speed increased, responsibilities were clear, and disputes disappeared.”

Closed-Loop Process – Secure Data

Thanks to Access Level Control, customer and project data at GreenHouse is strictly controlled. Every action is logged: who made the change, when, and what was changed.

Accidental deletions, overwrites, and incorrect updates have virtually disappeared.

The marketing department can now focus solely on creativity and monitoring advertising effectiveness, while sales teams can concentrate on customer care and closing deals. Monthly reports have also become more accurate, as data is no longer overlapping.

When a Small Business Operates Like a Large Corporation

Before, Mr. Long thought permission settings were only necessary for large companies. But after operating for a few months with GTG CRM, he realized it is the foundation for sustainable growth of a small business.

“We only have 15 people, but thanks to GTG CRM, everything runs as smoothly as a team of 50. No one encroaches on another’s responsibilities, and I no longer have to worry about data loss,” he said.

Besides Access Level Control, Mr. Long also utilized the CRM Module to manage contacts, Invoices to track project payments, and Automations to send thank-you emails to clients after project handover. However, he emphasized: “Without permission controls, all these other things would easily fall apart.”

Results After 4 Months

Just four months after implementing the new system:

• The number of operational errors in internal data decreased by nearly 90%.
• Project processing speed increased by 40% due to the elimination of overlapping permissions.
• New employees integrate faster thanks to clearly defined roles and responsibilities.
• The business operates transparently, with customer data being absolutely protected.

Conclusion

Access Level Control of GTG CRM is not just a feature, but the “backbone” that allows GreenHouse Interior to operate more efficiently, securely, and professionally.

With proper permission settings, Mr. Long no longer worries about “who does what,” but focuses on what matters most: developing services and customer experience.

“Before, I managed people. Now, the system helps me manage by principles – and everyone feels more comfortable.”
