Every business leader knows that an Enterprise Resource Planning, or ERP, system functions as the brain of an organization. It connects workflows across departments, from accounting to marketing to warehousing, while also collecting, storing, and managing business data. 

Beyond helping teams operate smoothly day to day, an ERP system gives executives access to critical data so they can make sharper, informed business decisions. 

Because an ERP system plays a central role in business operations, implementing one is never simple. The challenge grows for large organizations with multiple subsidiaries, complex processes, or many external systems to integrate. 

But complex challenges are exactly where Bluebik does its best work. 

In this article, Warat Laithong (Prame), ERP Advisory Director at Bluebik Group, shares 3 secrets behind implementing SAP S/4HANA Public Cloud for a company with annual revenue of THB 1 billion. 

The project came with every major challenge mentioned. 

First, the system had to consolidate data from 3 subsidiaries, each operating under a different business model. 

Second, it had to connect data from more than 15 storefronts. 

Third, it required integration with over 27 interfaces, including e-Tax systems, e-marketplaces, banking systems, warehouse management, and more. 

As if that were not challenging enough, there was one final condition: the entire system had to be completed and fully operational within 5 months. 

No matter how tough the challenge, Bluebik’s ERP Advisory team didn’t flinch. The team cracked every requirement on the list and delivered right on schedule, without a single day’s delay. 

So how did they pull it off? Prame is ready to share the full story. 

Secret #1: Nail Down Requirements With Total Clarity 

In the world of digital solutions development, everyone knows that requirements gathering matters more than almost anything else. 

“The main reason many SAP projects fall behind schedule is a lack of true understanding of the business process. Teams spend too long designing a workflow that fits the client’s needs. The worst case I’ve seen is when a finished system is tested with the client, only to discover it wasn’t what they wanted, forcing multiple rounds of rework before it’s usable. Also, missing requirements or hidden constraints often surface later because the system was designed without grasping the underlying business process,” says Prame, drawing on more than 20 years of experience in the industry. 

That is why the Bluebik team invested significant time in discussing and validating requirements with the client. 

“We combined the experience of team members with expertise in different areas. Instead of accepting every requirement as given, we asked the client where each came from, whether it was necessary, and what impact it would have if implemented.” 

“Through this process, we designed business processes and system functions covering almost 90% of the client’s needs during the design phase. When we moved to implementation, there was little rework. Everything progressed according to our plan.” 

Just as a business strategist must win the battle on paper before stepping onto the field, a systems developer must win at the system design stage before writing any code. 

Secret #2: Work Closely With Senior Executives 

A determined Bluebik team alone isn’t enough. The client’s senior leadership has to be just as willing to get in the boat and row alongside the team. 

For this project, Prame was upfront with the client from day one. Given the limited timeline, he explained the client would need to support the team with fast, decisive calls whenever a decision or direction was needed, so the project could keep moving without delays. 

“The client responded by sending C-level executives to join our requirements and system design sessions directly, making key decisions with us in real time. In some sessions, the CEO showed up in person. That level of involvement let us move fast, and it was a major reason the project came together on schedule. We weren’t working on this alone. It took real collaboration with the client, and in this case, the client’s cooperation was outstanding.” 

That shared commitment, everyone rowing in the same direction, is exactly what got the project across the finish line on time. 

Secret #3: Customize With Precision, Exactly Where It Counts 

A bit of context first. Our ERP Advisory team aims to implement as much of the software’s standard functionality as possible. This helps clients get full value and efficiency while keeping customization minimal. But some customization is almost always unavoidable. Every business has needs off-the-shelf software can’t cover. So the team customizes the points that matter most to the client’s business, tailored precisely to their needs. That’s why writing supplementary programs is standard in nearly every project. 

What made this project unusual was one particular interface the client relied on heavily, one that didn’t exist even in the base version of the software. So the team built that interface entirely from scratch, writing every line of code from the very first one. 

“As developers, once we’ve made a commitment to the client, we find a way to make it happen,” Prame says, describing the team’s mindset. 

That level of dedication didn’t just win the client over. It also became a reusable foundation for future projects that need a similar type of interface. 

Give every project everything you’ve got, and the results will follow, whether in the short term or the long run. 

More Than Successful Delivery: Building a System That Creates Real Business Impact 

More important than solving a difficult puzzle or meeting a tight deadline is seeing the systems the team implements actually work and create a clear, measurable impact for the client’s business. 

After this client’s new SAP system went live, the organization began seeing noticeable improvements across several areas of its operations. 

• Previously, the monthly financial closing process took dozens of days. With the new system, it was reduced to only a few days. 

• Previously, downloading and consolidating sales data from every e-marketplace took approximately two to three days. Today, the team can access daily sales summaries in real time directly through a dashboard. 

• Previously, information from each subsidiary had to be reviewed separately. The organization can now view data from all subsidiaries through a single dashboard, significantly improving overall visibility across the group. 

• Previously, manually counting inventory took almost an entire week. Today, the information can be accessed directly through the dashboard. 

Following the project’s success, Prame, the Project Director, shared how proud he was of every member of the ERP Advisory team. 

“Our team implemented a system this complex under an extremely tight deadline, with zero delays. And this wasn’t just a standard SAP rollout. We built highly complex custom integrations across 27 different interfaces. I genuinely believe that if it wasn’t our team, no one else could have pulled this off. That’s what I’m most proud of.”
