Additionally, factor in lead times for shipping and customs to avoid delays in product availability.
What steps should I take if I encounter disputes with a supplier?
In case of disputes with a supplier, maintain clear and documented communication regarding the issue. Refer to your contract for guidance on resolution processes. Start with informal discussions to seek an amicable solution; if that fails, consider mediation or arbitration as per the agreement. It’s also wise to engage legal counsel experienced in international trade disputes to navigate the complexities of different jurisdictions.
