The most reliable way is to work under a contract. If the client and the freelancer do not have a record of all agreements and terms, resolving potential conflicts may be especially difficult. Each party will insist their understanding is the most accyrate, but it's impossible to prove one's case without written confirmation. Therefore, it's worth concluding a service agreement that records:
• Subject matter;
• General conditions;
• Rights and obligations of the parties;
• Cost, deadlines, and payment procedures;
• Liability;
• Dispute resolution procedures;
• Other conditions.
In addition, a technical brief, which specifies the goals, tasks, and requirements, should be attached to the contract. With its help, it will be much easier to determine the quality of the freelancer's work.
Different specialists have different results, and these need to be accepted with consideration for the specifics. For example, a client pays an SEO specialist for the process of promoting a website or social network. It's impossible to get a quick result; this requires months or years. And even after this time, it can be difficult to determine how good the work was. For the performer, a good result might be getting a website into the top 10, while for the client, it might be the top 3. To avoid conflict, it's important to have a TS that clearly specifies the results that the business expects from the remote specialist.
The situation is different with the services of a programmer. Their work involves obtaining a tangible product - a website. In this case, workplace conflicts may arise if the client is dissatisfied with, for example, the loading speed, interface, usability, and other quality characteristics. To avoid disputes, it's worth defining detailed requirements for the product and then checking how well it meets them.
