OPUSS is an online business management software product from PROSOFT, designed for French micro-businesses, TPE/PME, and self-employed professionals. Its core use cases include managing quotes, invoices, e-invoices, and business declarations. The page clearly emphasizes that no installation is required, and that it can be accessed from PC, Mac, Linux, tablets, iPhone, and Android devices, making it suitable for small organizations that want to get started quickly.
The product covers day-to-day business workflows for small and micro enterprises: creating and sending quotes or invoices by email, managing time records, tracking fees and expenses, and calculating quarterly turnover declarations for URSSAF. For construction and craft users, it supports detailed quotes with photo-based descriptions and can automatically insert general terms and conditions. On collaboration, the official site mentions that companies can quickly deploy a small business network for remote collaboration or working with independent sales representatives, but it does not disclose details such as role permissions, approvals, or audit logs.
OPUSS is described as offering flexible per-user pricing, βall-inclusive and with no commitment,β but it does not publicly list specific prices, plan differences, or payment methods. The page provides access to a free trial and an online demo, which is useful for evaluating the product before making a decision. Deployment is clearly cloud-based SaaS, accessed through a secure login area with no local installation required; no self-hosted option is mentioned.
The official site emphasizes security, confidentiality, backups, and maintenance, and states that its e-invoices comply with EN 16931 / PDF-A3 France, indicating a strong focus on French e-invoicing and local regulatory requirements. However, the text does not explain GDPR details, encryption mechanisms, data center locations, permission models, security certifications, third-party integrations, or API developer support, so businesses should verify these points before purchasing.
Its strengths are that it is lightweight, easy to adopt, accessible across devices, covers the core workflows of small and micro businesses, and can be customized based on needs. Its weaknesses are the limited amount of public information, especially around pricing, integrations, APIs, and advanced permission capabilities. It is best suited to French self-employed professionals, construction tradespeople, small service providers, and businesses that need assistance with URSSAF declarations.
Access from mainland China is unknown. Since the productβs language, tax declarations, and e-invoicing standards are primarily designed for France, its direct business fit for Chinese companies is limited. For local Chinese finance, tax, inventory, and sales management needs, alternatives such as η¨ε, ιθΆ, and η ζ·ι may be more appropriate.
