HM Co commenced business on 1 October 2022, to provide specialist contract cleaning services to industrial customers. All sales are on credit. More favourable credit terms are offered to larger customers (class A) than to smaller customers (class B). All sales are invoiced at the end of the month in which the sale occurs. Class A customers will be given credit terms requiring payment within 60 days of invoicing, while class B customers will be required to pay within 30 days of invoicing. Since it is recognised, however, that not all customers comply with the credit terms they are allowed, receipts from customers have prudently been estimated as follows: Customer Within 30 Type days Class A Class B 60% 31 to 60 days 61 to 90 days 91 to 120 Bad days debts 50% 25% 30% 15% 5% 10% 5% The above table shows that customers are expected either to pay within 60 days of the end of the credit period, or not at all. Bad debts will therefore be written off 60 days after the end of the credit period. Budgeted credit sales for each class of customer in the first 4 months of trading are as follows: Customer Type October ($000) November ($000) December ($000) January ($000) Class A Class B Required: 100 60 150 80 200 40 300 50 (a) Complete the following budgeted cash inflows to be received by HM Co. from customers in each of the three months of November 2022, December 2022 and January 2023, based upon the prudently estimated receipts from customers.
