While there is no harm in hiring a Bubble developer from UpWork, directly approaching a bubble.io developers agency can be beneficial. The main benefit is that an agency will provide guidance and set goals that will successfully meet your project. With a thorough discussion with the experts, you can meet the planned goals and their deadlines.
An agency can offer you a better price for hiring a developer and offer different engagement models. A freelance Bubble developer might charge you more and have a hard time maintaining conversations and giving updates. An agency comes with a dedicated project manager that will cater to all your needs.
