Partnership in LLC Expense Tracking

[Jimmyhee Quach]

Hello! 

I have recently created an LLC with a partner of mine to make our first investment. Wanted to gather the great minds in the BiggerPockets community for pointers to get us started on the right foot:

1) What is the best way to manage business expenses made via personal credit cards? Our initial thought is we're intending on making purchases with our personal cards and tracking them on a spreadsheet (including receipts) so that it may be reimbursable by the business when we open a business account under the LLC.

2) What is the best way you've used to manage business expenses for your properties? (i.e. repairs, subscriptions, LLC costs, etc.)
