W2 Inc. (Headquarters: Chuo-ku, Tokyo; CEO: Hiroki Yamada; hereinafter "W2"), a provider of the B2B e-commerce platform "W2 BtoB," has launched an integration with "NP Kakebarai," a B2B payment service provided by Net Protections, Inc. (Location: Chiyoda-ku, Tokyo; President: Shin Shibata; hereinafter "Net Protections").
Background: Expanding Market vs. Analog Billing Challenges
The B2B e-commerce market is rapidly growing, with the domestic market size in 2024 reaching 514.4 trillion yen (a 10.6% increase YoY) and an e-commerce penetration rate of 43.1% (Ministry of Economy, Trade and Industry, "Report on Market Research on Electronic Commerce for FY2024").
However, invoice-based payments (Kakebarai) remain the mainstream in B2B transactions, leaving analog processes for credit screening and billing in place. As the need for comprehensive outsourcing of operational efficiency grows, W2 and Net Protections have reached this integration to further support the growth of B2B e-commerce transactions.
Details: Outsourcing Post-Payment Invoicing for E-commerce Sites
Through this integration, e-commerce businesses using "W2 BtoB" can implement post-payment invoicing for their B2B sites, achieving the following:
- Comprehensive outsourcing of credit screening, invoice issuance, and payment collection.
- Reduction of uncollected payment risks.
This supports the efficiency of B2B transactions, which previously relied on offline operations, and aids in expanding e-commerce sales.
