Anonymized Client Case Study
By Jack Ring |
I was introduced to this project by the NetSuite implementation partner itself. The implementation had stalled, and the client needed more hands-on help connecting its people, processes, and technical requirements. What began as client-side assistance eventually became a much broader effort to get the business across the finish line.
The situation at a glance
- The business: A multi-location equipment sales, rental, and service organization with serialized assets and complex service requirements.
- The challenge: Limited cross-functional ownership, extensive third-party customization, and a rental invoicing process that could not be trusted.
- The response: Reassess the approach, replace the unsuccessful rental and service components with focused NetSuite customizations, and prepare the operating teams for cutover.
- The outcome: A successful go-live and an ongoing consulting relationship.
An Implementation Without Enough Business Ownership
The company sold, rented, serviced, and calibrated specialized equipment across several locations. Its equipment could move through sales, rentals, returns, inspection, calibration, certification, and maintenance. These were not processes that could be designed in isolation.
The implementation partner had experienced senior consultants involved, and the client had invested substantial time and money. Yet the internal project team was stretched thin. The CFO participated as much as possible, while one technical employee carried an outsized share of the day-to-day coordination. Department representatives joined meetings when their particular subject came up, but few people had visibility into the complete operating model. Sales was especially underrepresented.
That is a difficult environment for any implementation team. Decisions that affect multiple departments cannot be made effectively when each department sees only its own portion of the process. The project needed consistent business participation, clear decision-making authority, and someone willing to connect the details from beginning to end.
When Customization Becomes the Plan
Leadership understandably wanted the new system to work for its employees. But accommodating nearly every requested behavior had become a substitute for deciding which requirements truly justified customization. A third-party rental and service application was extensively modified as the project progressed.
The issue was not that rental and service processes were simple. They were not. Serialized equipment, contract billing, returns, calibration, and certification create legitimate requirements. The issue was that the project had moved too far from a disciplined question: what can NetSuite already do, what must the business change, and what genuinely needs to be built?
The Breaking Point Was Billing
The most consequential problem surfaced in rental invoicing. The heavily customized billing process repeatedly produced amounts that did not match the business's expectations. The team spent additional time explaining scenarios, testing adjustments, and working through defects. Yet the numbers remained unreliable.
For a rental business, invoicing is not a peripheral feature. It is where contracts, equipment movements, dates, rates, exceptions, and accounting all meet. If the billing engine cannot be trusted, the organization cannot responsibly treat the implementation as ready.
Eventually the client made a difficult but necessary decision to discontinue that portion of the third-party solution. The decision acknowledged that further investment in the existing approach was not necessarily the safest path forward. It created room to solve the problem differently.
Replacing Complexity With a Focused Solution
By then I had spent enough time with the business to understand the requirements firsthand. Instead of attempting to recreate an entire commercial application, I developed a smaller solution centered on the workflows the company actually needed.
The design used NetSuite custom records to represent rental contracts and contract equipment, with additional records supporting service operations. Native NetSuite capabilities remained part of the solution wherever they fit. For the rental and service teams, I developed an embedded interface that gave employees a more practical, responsive way to work within NetSuite than the standard forms could provide for these particular workflows.
The most important piece was a purpose-built recurring rental billing engine. It did not simply assume the last invoice always represented a perfect billing history. If an invoice was deleted, corrected, or otherwise left a missing period, the system could recognize the gap and support billing the appropriate interval. Generated invoices remained available for review and approval rather than being treated as unquestionable output.
This was customization with a specific purpose: to make the operational and accounting process reliable, understandable, and maintainable.
Getting People Ready for Go-Live
Technical development alone was not enough. The business had multiple locations and employees whose daily work would change at cutover. We worked directly with the people who would operate the system, including front-counter managers whose sales activities had not been adequately represented earlier in the project.
Training meant visiting locations, walking through real transactions, and helping employees understand the process they would be responsible for after go-live. The goal was not to declare the software complete. It was to make sure the business could actually use it.
The company successfully went live following the recovery effort. That outcome was the result of changing direction when necessary, taking the billing problem seriously, and staying involved through the operational transition.
What This Rescue Demonstrated
Not every troubled NetSuite implementation needs to be restarted. Some need stronger internal leadership. Some need better coordination with the implementation partner. Others require a hard look at customizations that have become more complicated than the problems they were meant to solve.
In this case, the original partner recognized that additional help was needed and made the introduction. My role evolved from client-side support into hands-on coordination, architecture, development, training, and cutover assistance. The important change was not who attended the meetings. It was that the business gained a workable path from unresolved requirements to dependable daily operations.
The relationship did not end at go-live. The company continues to call when it wants to improve a process or introduce something new. One of the most useful questions I hear from its finance team today is simple: "What's the NetSuite way to do this?"
That is the lasting result I value most: not a system customized to imitate every old habit, but a business that trusts its ERP platform and knows when to use native capabilities and when to extend them.
Confidentiality note: This case study intentionally omits the client's identity, the implementation partner, the third-party software provider, precise financial figures, and identifying dates. Operational details are presented at a level intended to preserve the implementation lessons without identifying the organizations involved.
