[Please introduce this to the management and general affairs department] Update on the expense reimbursement system implementation case! We have successfully standardized the tasks that were concentrated at the end and beginning of the month. It's hard to believe we used to operate on paper.

  • NEW
  • OTHER

An article has been published about the case of introducing the expense reimbursement system "Rakuraku Seisan" at CTC First Contact, Inc. ~In the case of CTC First Contact~ To prevent situations where one might wonder "I thought I submitted it" or "Where are the documents?", they considered systematization. They were also managing payments to business partners using Excel, but there was a challenge to reduce and improve that workload. After the introduction, the integration with the transfer search significantly reduced the workload. They were able to change the payment site, which was impossible with paper operations. [Case Overview] ■Challenges before implementation - Uncertainty about the location of application documents ■Key points of implementation - Can be operated at a low cost - Flexible customization of settings *For more details, please refer to the related links or feel free to contact us.

Under the floor and in the attic... the "invisible spaces" are being re-evaluated now.

In an era of material shortages and rising material costs, what should we prioritize and protect?

  • NEW
  • PRODUCT

Under the floor and in the attic... "Invisible spaces" are being reconsidered now The environment surrounding the housing industry has changed significantly in recent years. Rising timber prices, increased costs of equipment, a shortage of skilled workers, and prolonged delivery times are not temporary changes but are becoming entrenched as structural changes in the entire housing industry. Furthermore, in recent years, the global surge in resource prices, the depreciation of the yen, and rising logistics costs have compounded the situation, leading to a generally unstable environment for housing-related materials. What was once taken for granted—that "necessary materials can be obtained immediately when needed"—is no longer a given. Additionally, the construction and equipment industries continue to face a serious labor shortage. In particular, the aging of veteran craftsmen who support the field is progressing year by year, while securing young talent is not easy. As a result, situations such as difficulty in scheduling construction dates, longer waiting periods until construction, and limited availability of contractors in certain regions are increasingly common nationwide. In the housing industry, there is a growing sentiment that "construction plans cannot be made with the same sense as before," whether for new builds or renovations, which is becoming the norm across the country. For more details, please be sure to read the 【related materials】【related links】 below. ↓ ↓ ↓

Please be sure to introduce this to the management and general affairs department. The first step towards improving operational efficiency and reforming work styles that every company needs! The basics of attendance management.

  • NEW
  • CATALOG

Attendance management is something that is expected of every company and should be addressed. When asked, "Are you doing it?" it might be more concerning to hear, "Are you doing it correctly?" which could make some responsible parties feel anxious. You may be using time cards for clocking in, but are unsure about overtime calculations. You might be having employees input data into Excel, but how does that stand in terms of legal compliance? You may be managing paid leave on paper, but there’s no room for double-checking. Employee resignations may be ongoing, but could this be due to overwork...? Why not review the various pros and cons of different attendance management methods and revisit the important aspects of attendance management from the "basics"?

We have released the materials on 'Attendance issues pointed out by the Labor Standards Inspection Office, and this was the common point!'

  • NEW
  • CATALOG

We have released a white paper titled "The Common Points of Attendance Issues Highlighted by the Labor Standards Inspection Office." This document provides a clear explanation of the challenges in attendance management that are likely to be pointed out by the Labor Standards Inspection Office, using specific examples. It addresses operational risks commonly seen in many companies, such as attendance aggregation in Excel, timekeeping management through self-reporting, insufficient management of paid leave, and rounding of overtime hours. Additionally, it introduces points that are often highlighted in inspections by the Labor Standards Inspection Office, such as "objective understanding of working hours," "unpaid overtime," "management of the 36 Agreement limits," and "compliance with the obligation to take 5 days of annual leave." This content can serve as an opportunity for companies that think "there have been no problems so far, so it's fine" to review their operations. Companies considering improving the efficiency of attendance management and strengthening compliance are encouraged to take a look. If you have any additional questions, please feel free to let us know.
