Process approved payments from Bill.com or set them up directly in the bank. Weekly Update the weekly cash forecast for expected vendor payments. Prepare AP aging for review. Month-End Close Reconcile all bank and credit card accounts (checking, PayPal, Stripe, AMEX, etc.). Reconcile AP between QBO and Bill.com ; calculate revaluation entries.
