A SaaS solution based on the intersection of CRM and SPM. Combined with a perfect usability and modern design, conceived for the requirements of small and medium-sized teams: Sales hierarchies, dashboards, and all sales related tools in one place. The sales of successful companies are becoming more and more complex due to the growing complexity of modern markets. Even small and medium-sized enterprises often have multi-level sales structures. However, we realized that many SMBs still manage their customer data in simple Excel spreadsheets, making comprehensive control of multi-level structured sales impossible. In the market for enterprise solutions, there are individual software products for customer management and sales control. Although these tools are networked, they require the provision of large financial and human resources. Our software 1sales is designed to meet this need for SMEs and offers an inexpensive solution that combines customer management and, based on this, easy-to-use sales control in one product.
