A customer or supplier extranet gives partners secure access to what concerns them: orders, invoices, documents, case tracking. Done well, it cuts repetitive calls and emails.

Customer extranet

Order and delivery tracking, downloadable invoices and online payment, ordering with customer-specific prices, documents, support tickets.

Supplier extranet

PO confirmation, invoice upload and payment tracking, lead-time and price updates, quality documents.

Security and rights

Strong authentication (2FA, SSO), fine-grained rights per company and role, access logs, GDPR compliance.

The core: ERP connection

An extranet is only useful if its data is right and current — see build or buy connectors.

A successful extranet is a customer who finds the answer before thinking of calling.

Why Symfony

Built-in security and permissions, API Platform, robustness and LTS longevity — see why Symfony. Budget: custom web application cost.

Symfony extranet: FAQ

A first scope (orders and invoices) usually takes a few weeks if the ERP exposes its data.
