Simply list the ERP systems and any financial tools you' have used. A list of common Financial ERP systems are: QuickBooks, Quicken, Peachtree, SAP, Infor, Visual, Xero, Microsoft Dynamics, Sage, Oracle JD Edwards, Epicor, Yardi, etc. Don't forget to mention your Excel skills, Google Spreadsheets, and being familiar with CSV files and uploading into different systems.
If you have no experience with any of these platforms than the suggestion would be to download free versions online and practice on a few by creating journal entries and chart of accounts. Then you can answer this question in the hypothetical rather than having no experience.
"I have worked with Quickbooks and XERO and my excel skills are advanced to say I can run macros and formulas. If you use a different platform I am a quick study and learn on my feet so I can master any platform with a little bit of training."
"I just graduated, so professionally I haven't worked with any of those platforms, but in college I had an entire Quickbooks class. We used Quickbooks and Waze accounting software as well as a dummy program of XERO. I like Quickbooks the best because of its ease of access."
"I' have worked with several over the years to include Quickbooks, XERO, Blackline and Peoplesoft financials. I liked Peoplesoft the best because it can be integrated into the HR process to track when people get promoted or terminated easier. It is able to work parallel with various other platforms as well. What program does your company utilize?"
