Me and my partner share a household and a business. We track shared household expenses (groceries, utilities, etc.) in YNAB. This is working fine.
As for the business, I have invested in a few enterprises with the agreement that my partner will pay me back with 5% interest. We've also agreed on a beginning (monthly) repayment amount which will increase over time. My investments have been paid out in seven installments (buying equipment, paying for services, etc.) over the course of three months. We want to begin repayments this month.
How do you folks deal with personal loans repayment tracking? It'd be nice to not need to figure out the APR, remaining balance, etc. and to have these details somewhere that we can both see. We're both android users and neither one of us are spreadsheet wizards. Right now I'm using a Google doc, but I don't want to figure out APR accrual for seven different origination dates.
Any good websites/apps you've run across for this?
