Interpretation:
Expected steps from students:
Answers should reflect professional, respectful communication and alignment with a written collection policy.
Customer Setup: Correct completion of names, addresses, terms, and credit limits; identification of missing tax or resale certificates.
Invoice Preparation: Accurate calculations of quantities, unit prices, taxes, and totals; correct due dates based on terms.
Cash Receipts Journal: Proper debit to Cash and credit to AR – specific customers; correct application to invoice balances.
AR Aging: Correct aging of balances and reasonable explanation of which accounts should be prioritized for follow-up.
Accurate and timely invoicing is essential because it starts the collection process and ensures customers know exactly what they owe and when it is due. Poor AR management leads to delayed collections, increased write-offs, cash shortages, and strained customer relationships. It also makes cash flow forecasting unreliable and can prevent the business from paying its own obligations on time.
By the end of Week 7, students should be able to set up customer accounts, create accurate invoices, record and apply customer payments, prepare AR aging reports, and understand the foundations of collections. Strong AR practices protect cash flow and support healthy customer relationships.
In later weeks, these concepts can be extended to bad debt, allowances, and more advanced revenue recognition topics.
