Heres what you need to take into consideration when researching the best way to invoice an international client: Establish the terms of sale beforehand. The terms should clearly cover the cost of all goods or services, the method of delivery, the shipping and billing address, and a payment schedule. Analyze the payment methods available to you and your client. Billing international clients can be tricky: make sure to do your research before committing to one specific method. Take international taxes and fees into consideration. When setting prices, remember to factor in all of the various taxes, customs fees, and shipping costs. These will all depend on the country where your client is located. Keeping your expectations clear and all terms negotiated will help your business mitigate risk and keep cash flow steady.
