On 4/1, our company entered into a contract to provide services to another company for $100,000. We received $10,000 deposit that was recorded in deferred revenue. By 12/31, we had completed 50% of the work and paid an additional $30,000 in cash, which was also recorded as deferred revenue. What is the adjusting entry on 12/31? Do I debit revenue $$40 or 50K and credit deferred revenue $40 or $50K? Or do I debit receivable $50K, credit revenue $50K?
