What should I do when I meet a customer who doesn't pay for a good photo album when doing digital design?

According to the staff of the post-design studio of Tianyi Studio, a studio in Beijing felt a little dissatisfied after seeing the photo albums they designed and asked for redone. Later, Hunan Tianyi Studio was asked to design several other photo albums, but no payment was made after all the photo albums were designed. No matter who is right or wrong in fact, the resulting problems can not be ignored. With the development of wedding photography industry, photo studios pay more and more attention to and rely on digital post-production. However, because many places have off-season and peak season, which has a certain impact on the stability of designers in digital post-production, many photo studios and photo studios choose to outsource post-production design. Of course, outsourcing saves a lot of energy and cost for photo studios and photography studios, and also gives excellent digital post-designers more room for development. However, there are also many problems. The following small series collected some common questions and suggestions from netizens for everyone to share. First, because the post-design is not a physical transaction, the cooperation process is generally to communicate with customers. Customers send > customers pay > reply, mainly through the network and telephone communication. It is suggested that when cooperating, we must sign a contract and explain the breach of contract and the corresponding responsibilities to ensure the rights and interests of both parties. Second, after designing the work, the post-design company of the studio cannot contact the photographer directly. If the studio unilaterally denies the quality of the design works, it will be difficult to safeguard the rights and interests of the design company in the later stage of the studio. It is suggested that post-design companies take some necessary measures to protect their rights and interests from infringement, such as showing some finished products to cooperative customers or compressing files and encrypting transmitted files.
