~ A high-efficiency customer attraction strategy where homebuyers come in saying "I saw it on ○○!" and a product/design strategy that is specifically requested with "I want to build with Harbor!" ~ In an era where simply creating a "good house" is not enough to survive, the environment surrounding local construction companies is becoming more challenging than ever due to rising material costs, labor shortages, and intensified competition with major companies. In this context, Harbor House, which has been established for 19 years in the fiercely competitive Niigata Prefecture, has achieved an annual completion of 450 houses and is now ranked number one in the number of construction starts in Niigata Prefecture. Its strength lies not in a single charismatic leader, but in a thoroughly refined "system." Customers who say, "I came after seeing your website" are reliably guided to contracts through a highly efficient sales flow based on "batting average management." In this online seminar, we will generously share the know-how of customer attraction, product, and management practices that Harbor House implements with business owners. We will present the shortest route to becoming a "construction company that continues to be chosen" in your business area. ◇ Detailed information and application https://x.gd/pUe2b ◇ Phone inquiries TEL: 025-383-8881
