Vyfakturuj Invoices for OpenCart — Vyfakturuj.cz invoices from orders

Vyfakturuj Invoices issues an invoice in the Czech service Vyfakturuj.cz from an OpenCart order: the buyer (a private person or a company with IČO and DIČ), the lines, shipping, VAT and the currency. In Pro the invoice is issued on a status and sent to the buyer, and a refund creates a correction document. The partner list in the Vyfakturuj public API names Toret for WooCommerce, PSModuly for PrestaShop, Upgates and Forga; OpenCart is not among them.

What the free version does

A panel on the order page with the Create invoice button. The checkout gets IČO and DIČ fields (a button in the settings creates them); an empty field means a private buyer. A second click does not create a second invoice, a Vyfakturuj outage puts the entry into a queue with a retry, and an answer lost after the write gives no duplicate.

What Pro adds

An invoice on the chosen status and an e-mail to the buyer through Vyfakturuj, and a correction document on the refund status (once).

Under the hood
