| Implementation and onboarding | Look into the setup process and support materials. Are there tutorials, templates, or user guides to help your team get started quickly? Poor onboarding can delay the benefits you expect from the tool. |
| Cost | Compare the pricing against your budget. Are there hidden fees or additional costs for certain features? Consider the total cost of ownership, including any support or maintenance fees. |
