Possible disadvantages

• Limited Features
  Compared to other advanced invoicing software, Simple Invoices may lack some features like advanced reporting, automated reminders, and integrations with other business tools.
• Self-Hosting Requirements
  Users need to host the software themselves, requiring some technical knowledge and resources for server management and maintenance.
• Inconsistent Updates
  As it is a community-driven project, updates and fixes may not be as frequent or reliable compared to commercial software.
• Security Concerns
  Hosting your own invoicing system can pose security risks if proper measures are not taken, unlike cloud services which often have dedicated security teams.

• No Installation Required

Possible disadvantages

• Uncertain Reliability
  Third-party GPT wrapper websites often depend on underlying API access that can be unstable, rate-limited, or discontinued without notice, affecting consistent availability.
• Data Privacy Concerns
  Using an unofficial third-party service to process conversations raises questions about how user data and conversation history are stored, used, or shared.
• Limited Transparency
  It may be unclear which underlying AI model version is being used, how up-to-date it is, or what modifications have been made to the base model's behavior.
• Potential Hidden Costs or Ads
  Free-to-use AI wrapper sites often monetize through ads, premium upsells, or data collection, which may not be clearly disclosed to users upfront.
• Lack of Official Support
  Unlike official AI platforms, unofficial wrapper sites may lack dedicated customer support, regular updates, or accountability if issues arise.
