I'm looking for a software solution that allows me to store information about clients of my service business such as personal details, contact details, related documents etc. It also needs export options (pdf documents or Excel spreadsheets) and backup options. Now instead of doing an unwieldy spreadsheet (Excel) and related folders of files, I would like something that is multi-user, hosted locally and has a beginner-friendly interface. Ideally it's completely free and open-source (I realize of course that this can't include any service). To that end, I have installed SuiteCRM on a local VM to test out, but I don't have the experience to know if it's right for my business/needs or if it's too feature-full and unnecessary. Your input would be appreciated.
