Opalon - 2026 Pricing, Features, Reviews & Alternatives

Opalon is a quotation and invoicing management software designed for independent contractors and small businesses in the building and public works sector. The platform consolidates the complete quote-to-cash cycle including estimates, invoicing, automated payment reminders and collections management into a unified management tool. Opalon targets skilled tradespeople who require compliant financial documentation while prioritizing field activities over administrative tasks.

Opalon provides comprehensive quotation and invoicing functionality with professional document generation capabilities that include automatic sequential numbering, tax calculation, PDF output and integrated email distribution. Estimates can be created in minutes and converted directly into invoices with a single action. Automated reminder workflows trigger follow-up emails at configurable intervals after invoice due dates and a real-time treasury dashboard displays outstanding receivables. Native mobile applications for iOS and Android enable field data capture of materials, labor hours and job details with offline synchronization to support intermittent connectivity. A unified dashboard presents agenda scheduling, quotation pipeline, invoice status and payment collections in a centralized workspace.

Opalon offers subscription tiers that scale from essential functions to advanced capabilities. Basic features include unlimited quotes and a limited number of invoices per month alongside automated reminders. Higher tiers add client portal access, online payment processing, credit note management, recurring contract handling and multi-user access with granular permissions. Advanced tier features encompass catalog management for professional services, expense tracking, AI assistant support and compliance exports tailored to French fiscal requirements.

Opalon maintains data integrity through atomic sequential numbering by fiscal year to prevent duplicate invoice numbers under concurrent use. Immutable database records lock invoice numbers, dates and amounts once documents are issued to safeguard against modification. The underlying architecture enforces strict multi-tenancy isolation at the database level with row-level security and supports time-based one-time password authentication for enhanced account protection. GDPR compliance is assured through one-click data exports in standard formats, irreversible anonymization on request and documented retention policies. Continuous integration and deployment pipelines execute comprehensive automated tests to validate calculation logic, status transitions and fiscal regulations with each release. All customer data is hosted exclusively on French infrastructure to meet local audit and regulatory standards.
