Invio

Invio reimagines invoicing by stripping away the complexity and subscription costs of traditional invoicing platforms while maintaining professional functionality. As freelancers and small businesses grow tired of paying monthly fees for bloated CRM systems when they only need simple invoicing, Invio provides a focused alternative that prioritizes speed, privacy, and self-hosting. The minimalist design philosophy ensures the application remains fast and intuitive, eliminating the learning curve associated with enterprise invoicing software while providing all essential features for professional billing.

Common Use Cases

Small consulting firms deploy Invio to handle client billing without paying per-user subscription fees, sharing password-free invoice links via email that clients can view and download without creating accounts. Creative agencies leverage Invio's multilingual support to bill international clients in their preferred language, while the self-hosted architecture ensures sensitive financial data remains under agency control rather than stored on third-party servers.

Why deploy Invio on Hostinger VPS

Deploying Invio on Hostinger VPS eliminates recurring subscription costs while maintaining professional invoicing capabilities under your complete control. The VPS environment provides reliable access to invoice generation and client links from anywhere, ensuring you can create and share invoices during client meetings or while traveling without dependency on third-party service availability. With persistent storage, years of invoice history and product catalogs are preserved as valuable business records for tax purposes, client disputes, and financial planning. Self-hosting on VPS infrastructure allows customizing the application, implementing backup strategies matching business requirements, and avoiding the privacy implications of storing sensitive financial data on third-party platforms. The lightweight design ensures Invio runs efficiently even on entry-level VPS plans, while the single-container deployment simplifies updates and maintenance compared to complex multi-service invoicing platforms.
