Vendus POS & Invoicing

Ask Claude about your Vendus sales: invoices, totals per store or payment method, clients and products.

Read-only access to a Vendus (Cegid Vendus) account through its official API v1.1. Lists invoices, simplified invoices, invoice-receipts and credit notes with totals, opens any document with its lines, VAT breakdown and payment methods, and aggregates sales per day, month, store, payment method or document type over any period. Also lists clients, products with prices and stock, and stores. Nothing is ever written to Vendus.

FAQ

Can Claude issue or change invoices?

No. Every tool is read-only; the connector only performs GET requests against the Vendus API.

What does the API key give access to?

Exactly what the Vendus user who owns the key can see. Create a dedicated user with limited permissions if you want to restrict Claude to one store or area.

How are sales totals computed?

FT, FS, FR and FG documents are added, NC credit notes subtracted and canceled documents ignored. Documents paid with several methods are split proportionally. Invoices settled later by a separate receipt show no payment method on the invoice itself.

Are there limits?

Vendus pages collections at up to 1000 items and applies per-account rate limits (reported in Rate-Limit-* headers). A sales summary walks every document of the period, up to 5000 per document type, so narrow the period for very large accounts.
