Your friend, Wendy Geiger, owns a small retail store that sells candies and nuts. Geiger acquires her goods from a few select vendors. She generally makes purchase orders by phone and on credit. Sales are primarily for cash. Geiger keeps her own manual accounting system using a general journal and a general ledger. At the end of each business day, she records one summary entry for cash sales. Geiger recently began offering items in creative gift packages. This has increased sales and substantially, and she is now receiving orders from corporate and other clients who order larger quantities and prefer to buy on credit. As a result of increased credit transactions in both purchases and sales, keeping the accounting records has become extremely time consuming. Geiger wants to continue to maintain her own manual system and calls for your advice.

Required: prepare a memo to her advising how she might modify her current manual accounting system to accomodate the expanded business activities. Geiger is accustomed to checking her ledger by using a trial balance. Your memo should describe the advantages of what you propose and of any other verification techniques you recommend.
