A lot of businesses that want to create such products do not have in-house development teams. In such a situation, there are two main solutions. For example, they can hire freelancers or a professional IT agency. Though the work of a freelance billing software developer can be cheaper, there can be issues with long-term cooperation with such a specialist, as well as other risks. Unfortunately, not all freelancers demonstrate a diligent level of responsibility. When you work with a reliable company, like Anadea, your rights are better protected. Plus, you can be sure to get a full cycle of development service following the set terms. Cooperation with freelancers can be a good choice for small urgent tasks. But for long-term projects, it's better to work with professional agencies.
