What is CoinSimple ?
CoinSimple allows consultants and online merchants to easily accept bitcoins either through a bitcoin payment processor (BitPay, Coinbase, GoCoin) or directly to their deterministic wallet (Electrum, Armory, Trezor) or to any non-deterministic bitcoin wallet. One can use the CoinSimple web app to issue invoices directly, Wordpress eCommerce (see demo site or plugin page), WooCommerce (see demo site or plugin page), Magento (see demo site or plugin page), to sell products through their store.
