Best Invoice Guru Use Cases & Applications
On-Site Job Completion
A plumber finishes a job at a client's home and immediately creates a professional invoice on their phone while still on-site. They add photos of any additional parts purchased, apply their VAT rate, and email the invoice before leaving. The client receives it instantly and can pay via the included payment link.
Monthly Retainer Services
