SUCCESS STORIES OF COMPANIES THAT HAVE ACHIEVED RESULTS WITH UPWARD
CRM refers to a management approach and system that centrally manages customer information and relationships to simultaneously increase sales and customer satisfaction.
Many people may think that “CRM” is simply “customer management software,” but in reality, it encompasses two distinct aspects: the system itself and business strategy. Understanding both of these aspects is crucial for making the most of the tool .
Basic Definition of CRM
CRM stands for Customer Relationship Management.
This refers to a system that consolidates customer basic information, purchase history, inquiry response logs, and communications with sales representatives in a single location for use across the entire organization.
As a strategy, CRM is based on the concept of “maximizing LTV (lifetime value) by nurturing long-term relationships with each individual customer.” The tools are merely a means to execute that strategy; no matter how advanced the system you implement, it will not be effective if your implementation plan remains vague.
Differences from SFA and MA

The Differences Between CRM, SFA, and MA
SFA focuses on managing sales progress and sales activities, streamlining the sales process prior to order placement. MA nurtures leads through advertising, email, and content, handling the stage before handing them off to the sales team.
The following article provides a detailed overview of the roles and responsibilities of SFA, MA, and CRM.
The diversification of customer touchpoints is the direct reason behind the growing interest in CRM.
Customers now interact with companies through multiple channels—including the web, social media, phone, email, and in-person visits—and managing each of these touchpoints separately results in a fragmented customer experience. Furthermore, as "data-driven decision-making" has become essential in the context of digital transformation, CRM is gaining increasing attention as the foundation for moving away from sales approaches reliant solely on intuition and rule of thumb.
The following article provides a detailed overview of the diversification customer touchpoint and strategies for addressing them.
The CRM market is expanding not only domestically but also on a global scale, with technological innovations such as the use of AI driving adoption. Domestically, the range of companies adopting CRM has expanded from large corporations to mid-sized and small businesses.
The adoption rate of cloud services among businesses has reached 80.6%. However, many companies are still in the process of migrating to systems specialized in customer management, such as CRM and SFA, and as a result, customer data remains scattered even though they are using the cloud.
Globally, several major platforms—including Salesforce, HubSpot CRM, Microsoft Dynamics 365, Zoho CRM, and Odoo—are driving the market.
In Japan as well, in addition to these global SaaS solutions, there is a growing selection of tools optimized for Japanese sales practices.
This approach is particularly widespread in the B2B sector, where companies have a large customer base and sales representatives spend much of their time on the road.
In industries such as manufacturing, food and beverage, and medical devices and pharmaceuticals, field sales serve as the primary sales channel, and centralized management of visit histories and sales meeting information directly contributes to increased revenue.
In these industries, sales representatives visit multiple clients each day, so there is log growing log for mobile-friendly CRM systems that allow them to quickly log while on the go or after a visit.
CRM Trends for 2026: AI, IoT, and Self-Service
According to an IPA survey, the percentage of companies undertaking digital transformation is expected to reach 77.8% in fiscal year 2024, and nearly half of these companies are enthusiastic about adopting generative AI.
In light of these developments, there are three trends in CRM usage that deserve particular attention in 2026.
AI Applications: There are an increasing number of scenarios where AI assists sales representatives in making decisions, such as analyzing sales meetings, suggesting optimal next steps, and detecting customer churn risks.
IoT Integration: We are beginning to see examples of companies linking operational data from manufacturing equipment and vehicles with their CRM systems to automate predictive maintenance services and service call triggers.
Self-service CRM: There is a growing trend toward integrating systems that allow customers to access a portal to check their order history and inquiry status with the CRM data infrastructure.
CRM is a multifunctional system that supports every stage of sales activities, from customer management to analysis. While the areas of strength vary by product, here we outline four representative functional categories.
Customer Information and Sales Opportunity Management
In addition to basic customer information (company name, contact person, contact details, industry, and company size), we consolidate transaction history, contract details, and billing information into a single record. By setting the status (proposal in progress, quote submitted, or scheduled to close) and likelihood of success for each sales opportunity, managers can gain a comprehensive overview of the entire sales pipeline and make informed decisions regarding resource allocation.
Activity log and Visit History
log contact history—including visits, phone calls, emails, and online meetings—in chronological order and links them to the next action and the assigned representative. UPWARD is designed to allow users to complete log directly from their smartphones immediately after a visit, log location data and log.
Reporting and Analysis Features
The KPI dashboard visualizes the number of visits, the number of sales meetings, the conversion rate, and sales forecasts in real time, enabling managers to detect anomalies in the data early on.
You can also segment customers using RFM analysis (last purchase date, frequency, and amount) to design a targeted approach for high-priority customers.
Integration with External Tools
CRM systems demonstrate their true value when integrated with other systems rather than operating in isolation. Major CRM platforms have ecosystems that include marketing automation tools such as Marketo, as well as email, calendar, and accounting systems, serving as a foundation for integration with external tools.
Advantages and Disadvantages of CRM
While CRM offers significant benefits, it is important to make an informed decision that takes into account both the advantages and the challenges involved in ensuring its successful adoption.
While there is plenty of information suggesting that “implementing a CRM system makes work easier,” many companies have failed in their implementation efforts. Making a decision after accurately assessing the pros and cons is what determines whether the implementation will be a success or a failure.
Eliminates the reliance on individual employees for customer information
A situation where “only [Name] knows everything about Company A” continues to create risks associated with employee turnover and high handover costs. By consolidating information in a CRM system, anyone can understand a customer’s current situation and respond accordingly, thereby boosting the team’s overall sales performance.
Cost savings through customer retention
Using CRM to strengthen relationships with existing customers and prevent churn is a critical business priority on par with acquiring new customers. Retaining existing customers is more cost-effective than acquiring new ones and directly contributes to maximizing LTV (lifetime value) through ongoing transactions.
Enables data-driven decision-making
By leveraging CRM, you can make decisions that aren’t based solely on experience or intuition. A CRM system that stores behavioral logs and results data is essential for analyzing factors such as “the behavior patterns of top-performing sales reps” and “customer segments with high churn rates.”
Common challenges and examples of failures that can lead to disadvantages
The most common reason for implementation failure is that the system “failed to take root on the front lines.” Staff stop using it for reasons such as too many data entry fields, having to return to the office to enter data, or feeling that the data they enter doesn’t actually benefit their work.
Initial costs are also a factor that cannot be overlooked. In addition to licensing fees, costs may arise for customization, data migration, and employee training.

It is important to set clear goals for using the CRM system after implementation
If you implement a CRM system simply because you expect it to boost sales, you’re likely to fail. This is because a CRM is, at its core, merely an information platform—it requires a strategic operational plan that defines “what data to input” and “how to utilize it.” The true essence of CRM implementation lies not in simply adopting the tool, but in how you use it to transform your relationships with customers.
Characteristics of Companies Suited for CRM
The following are the characteristics of companies that are able to achieve results by leveraging CRM.
There are hundreds of companies to manage
The sales cycle takes more than a month
Field sales is the primary channel
There are multiple sales representatives, and a system for sharing information is needed.
Characteristics of Companies for Which CRM Is Not Suitable
On the other hand, companies with the following characteristics are often not the best candidates for CRM implementation.
With fewer than a few dozen customers, Excel is sufficient for management
Transactions are primarily one-time, so there is no need to build ongoing relationships
There are one or two sales representatives, and communication is effective
A small customer base and short sales cycles
Comparison of CRM and Excel Management
The difference between CRM and Excel-based management depends on the scale of the operation and the specific challenges involved. Many companies still manage their customer data using Excel, and there is nothing inherently wrong with that.
However, as the organization grows and the number of customers, sales staff, and sales meetings increases, there will come a point where Excel is no longer sufficient to handle the workload.
Real-time editing and sharing are not available
Update oversights have become a chronic problem
The analysis is time-consuming
If data isn’t put to use, people lose motivation to enter it; however, aggregating data in Excel requires knowledge of functions and pivot tables. Manual work is required every time the data is updated, increasing the manager’s workload. As a result, a vicious cycle ensues in which sales staff stop entering data.
For case studies on migrating from Excel to CRM and specific points of comparison, please refer to the following article.
Guidelines for determining the right time to transition to CRM
Specifically, if any of the following situations apply, it’s a sign that you should consider migrating your CRM.
The number of clients we manage has exceeded 200
The number of sales representatives has increased to five or more
The number of sales meetings per month exceeded 100
Every time an employee leaves or is transferred, it takes more than a week to hand over customer information
Managers cannot see in real time which manager is handling which customer
While these values are merely guidelines, if several of them apply to you, it’s time to start considering a transition.
How to Choose and Implement a CRM System
If you choose a CRM based on the wrong criteria, it won’t take root, so it’s important to identify the one that’s right for your company by evaluating it from five key perspectives.
There are dozens of CRM systems on the market, offering a wide range of options from both domestic and international vendors.
That’s precisely why, if you start comparing options without first clarifying what your company actually needs, you’ll be overwhelmed by the features and end up making the wrong decision.
5 Key Points to Consider
We’ve summarized five key points to check.
Compatibility with Industry and Sales Style
Companies with a field sales focus—mobile usability and visit management features are essential
Companies focused on inside sales—integration of phone and email systems and lead scoring are crucial
It is important to choose a tool that fits your company’s sales style rather than one that is merely “average.”
Mobile-friendly
For sales teams that spend a lot of time in the field, the quality app directly determines whether the implementation is a success or a failure. Be sure to verify that it offers the same functionality as the desktop version, works in offline environments, and requires minimal input steps.
Integration with other systems
Check in advance to what extent the system can integrate with the SFA, MA, email, and accounting tools you are already using. Whether API integration is available and whether customization fees apply are also important points to verify.
Cost Structure
We will compare not only the monthly license fees but also the total cost of ownership (TCO), which includes initial setup costs, customization fees, support costs, and additional storage fees.
While the typical price range for SaaS-based CRM systems is generally between 2,000 and 15,000 yen per user per month, it is important to verify the costs of the plan that includes the necessary features and any additional options.
Support System
Check whether Japanese language support is available, the methods for contacting support (phone, chat, email), and whether implementation support or training programs are provided. In particular, the quality of initial setup support and follow-up assistance to ensure successful adoption on-site significantly impacts long-term usage. Costs also tend to vary by vendor, so be sure to verify them.

We will proceed with the CRM implementation in the following five steps.
Issue Identification: Identify specific current problems (such as reliance on individual expertise, the burden of data entry, and difficulties in analysis) and prioritize them based on the need for resolution.
Requirements Definition: Identify essential features, desirable features, and unnecessary features, and determine the mobile-to-PC ratio and external systems that need to be integrated
Vendor Comparison: Narrow the field down to 3–5 companies, request proposals, and watch demos. During the demos, ask them to simulate “typical sales scenarios at your company.”
Trial: Be sure to conduct a free trial or a pilot test with a limited number of users. Be sure to check the feedback from end users.
Phased rollout: Start by implementing only the basic features, and add more once you’ve confirmed they’ve been adopted. Trying to use all features at once will overwhelm the team.
Pitfalls to Watch Out for When Comparing
When comparing options, it’s important to evaluate them from multiple perspectives. Even if one aspect is excellent, if other aspects don’t align with your company’s needs, you won’t be able to make use of it.
It has too many features, so it isn't used on the job site
Even a high-performance CRM that made a good impression during a demo is useless if the front-line staff can’t make full use of it. It’s important to compare options while constantly asking yourself, “Does our sales team really need this feature?”
Choose based solely on price
Even if the initial costs are low, unexpected expenses can arise from customization or additional options. Furthermore, if a low-cost tool lacks necessary features, you’ll need to implement additional systems, which will ultimately drive up costs.
Selecting based solely on the administrator's perspective
A classic recipe for failure is when the IT department or managers select a system on their own and roll it out without having field sales representatives verify its usability.
The key to successful adoption is to involve end users from the selection phase and make “whether I would want to use this” one of the evaluation criteria.
CRM Case Studies
By reviewing case studies of companies that have actually implemented CRM, you can get a clearer picture of how your own company could utilize the system. Let’s use these case studies to see if the system is actually being used after implementation and to visualize what your own implementation might look like.
Case Study —Achieving the "Assetization" of Activity Data digital transformation | TS Tokyo Co., Ltd. (Interior and Exterior Construction)
TS Tokyo Co., Ltd., which specializes in interior and exterior renovation work for office buildings (including restoration to original condition, cleaning, and coating), operates under a system where technical staff handle the actual construction work separately from the sales staff.
The challenges we faced were that customer information was tied to specific sales representatives, requiring us to rebuild relationships from scratch every time staff members changed, and that conversation histories between sales staff and customers, office floor plans, and instructions for construction crews were not managed in a centralized system.
The implementation of UPWARD not only streamlined collaboration between sales and technical staff but also led to the creation of a new inside sales role. By centralizing and consolidating customer information, we were able to ensure seamless collaboration across departments and among staff members, even with separate sales processes.
In addition, the dashboard feature makes it easier to visualize sales leads and revenue progress, which is useful for planning future sales strategies and training new staff members.
Summary—An Overview of CRM and Why You Should Get Started Right Away
CRM is essential to leveraging customer assets in business. Here, we’ll summarize the key points discussed in this article into four main categories.
CRM involves both strategy and tools: simply implementing a system isn’t enough. It must be accompanied by a clear strategy for how to nurture customer relationships.
Don’t miss the right time to migrate from Excel: Once you exceed thresholds such as 200 clients , 5 sales representatives, or 100 monthly deals, it’s time to consider migrating.
The top priority in selection is whether the tool is practical for field use: We base our decision on whether it fits our company’s sales style and mobile environment, rather than on the sheer number of features .
Increase Adoption Rates Through Phased Implementation: Start with basic functions first , then move on to the analysis and AI utilization phase once data has been accumulated
Once you start considering implementation, begin by listing the current challenges in your customer management system. Identifying which of the following issues—information being tied to specific individuals, the burden of data entry, or delays in sharing information—is the most serious for your company is the starting point for selecting a CRM system.
Frequently Asked Questions
We’ve compiled a list of common basic questions about CRM.
What is the difference between CRM and SFA?
The purpose of CRM is to manage relationships with all customers, including existing ones, with the primary performance metrics being LTV improvement and customer retention.
SFA focuses primarily on tracking the progress of prospects in the sales pipeline, with the goal of improving conversion rates and streamlining sales processes.
Many companies use CRM and SFA in conjunction with one another, and there are platforms, such as Salesforce, that offer both functions as a single integrated solution.
How much does it cost to implement a CRM system?
For cloud-based (SaaS) CRM systems, the typical price range is 2,000 to 15,000 yen per user per month.
However, please note that this figure covers only the license fee; costs for initial setup, data migration, training, and customization may be charged separately. We recommend comparing the "total cost for the first year" before implementation.
Do small and medium-sized businesses need CRM?
The decision depends on the number of customers, the frequency of sales interactions, and the size of the sales team. If you have fewer than a few dozen customers and Excel is working well for you, there may be little need to switch to a CRM system.
On the other hand, if your customer base is growing rapidly during a growth phase, or if you’re facing handover costs due to reliance on specific individuals, implementing the system early can help prevent future disruptions.
Should CRM and MA be implemented at the same time?
We generally do not recommend implementing both systems at the same time. The priority should be to establish centralized management of customer data and log within the CRM. Once data has been accumulated and the sales team is using the CRM on a daily basis, integrating it with MA to automate lead nurturing will increase your chances of success.
Launching two systems simultaneously carries the risk of causing confusion on-site and increasing the workload for training.
What are some tips for successfully implementing CRM with a field sales team?
The key lies in the three pillars of "input, utilization, and team-driven implementation."
Minimize input: Create a system that makes it easy to create logusing templates , voice input, location-based check-ins, and more
The experience of seeing your data come back to you: By offering features such as visit priority suggestions, route optimization, and reminders for next steps, our CRM provides a tangible sense of how it makes your work easier.
Managers put it to use: When managers use CRM data for feedback and coaching, frontline staff begin to feel that their data entry is worthwhile.
