You can even create scenario-specific combinations, such as matching "lightweight battery + solar charging panel" sets for small yacht customers.
Cost Control: Reducing Costs and Increasing Efficiency from Supply Chain to Operations
Compress costs upstream by optimizing procurement and inventory. Establish long-term direct supply cooperation with core manufacturers to extend the payment term to 60-90 days, reducing capital turnover pressure. Lock in preferential procurement prices through annual purchase volume commitments, cutting costs by 10%-15% compared to scattered purchases.
Precision Promotion: Stimulating Sales While Ensuring Profit
Design promotional activities based on market cycles and customer needs. For seasonal promotions, launch "pre-order discounts" before the peak sailing seasons in spring and autumn-for example, a 10% discount on the total battery price with a 20% advance deposit to lock in orders in advance. During off-seasons, launch "trade-in" programs for inventory products, allowing old batteries to be discounted by 10%-20% to offset the cost of new ones, activating idle demand.
In customer-tiered promotions, offer an 85% discount on the first order for small maintenance shops cooperating for the first time, and provide annual rebates for long-term cooperative large shipping companies. You can also leverage policy dividends-for instance, converting new energy ship subsidies into "post-subsidy special prices", which is both compliant and enhances price attractiveness.
Channel Deepening: Building Differentiated Competitive Barriers
Wholesalers need to strengthen the advantages of "regional exclusivity" or "category exclusivity". Sign agreements with manufacturers to obtain exclusive distribution rights for a series of high-end batteries in specific regions, maintain pricing initiative through scarcity, and provide exclusive supply support to downstream retailers to bind cooperative relationships.
Retailers should focus on localized service capabilities-for example, setting up professional installation teams to provide one-stop services of "battery purchase + free installation + on-site debugging". Embed service costs into pricing to improve customer experience while avoiding pure price competition.
In terms of online-offline integration, wholesalers can build B2B ordering platforms and launch "free shipping for full-value online orders".
Retailers can post battery maintenance tutorials on short-video platforms to attract traffic, while offline stores provide experience and after-sales services, forming a profitable closed loop of "content customer acquisition + physical conversion".
