Erply, the POS payments startup, has quietly racketed up its pricing for retail chains.

Erply was charging a base free of $200 per month per retail chain, and $200 per additional retail store. But Erply has raised that base fee to $500 per month in recent weeks.

Erply has also extended telephone customer service to its “small” store clients, where previously it offered none. Those clients pay a base of $100 per month and $70 per month per store.

Based in Estonia, Erply offers a POS produce, which allows for online and offline retail payments. The POS software also works from an iPad. The company claims more than 20,000 users globally. 

Just this week Erply introduced a new version of its system. Among the upgrades was a retooled dashboard.

Erply has received slightly more than $2 million of venture funding today, according to CrunchBase.
