In any business it is imperative that proper Accounts Receivable ledgers be maintained, and this is especially important for community associations.   It should be a simple task as every month, quarter, or year an amount is due and when its paid the ledger goes down to zero.  Not too much math involved here, and when a unit owner is paying on time it’s quite simple.  Yet, what happens when a unit goes delinquent, or when payments come in on an irregular basis and the ledger is not kept properly?  That I can answer in one word, and that would be “trouble.”
