Start-up costs were $1,000: sewing machine ($500), decorative supplies ($300), professional grade glue gun ($100), and 100 pairs of plain flip flops ($1/pair).

Due to the seasonal nature of demand, Sophia likes to have approximately 20 decorated pairs in inventory, in order to meet rush orders.

FFs are customized flip-flops, sold online. They have been relatively popular with $10,000 sales last past year.

Sophia estimates sales will grow by 8% this year.

The average selling price per pair is $10. The low frill pairs sell for $8 (Number of units is approximately 25% of pairs sold). Highly decorated pairs sell for $20 (number of units is also approximately 25% of pairs sold).

Cost of materials for embellishing and customizing the flip-flops range from $2.50 - $8.00 per pair.

Sophia estimates it takes her 30-90 minutes (.5 - 1.5 hours) to decorate one pair, depending on the complexity of the design. She isn't sure what value to assign to an hour of her labor.

Shipping is paid for by the customer, if needed.

Transactions are PayPal only.

The website and PayPal fees are $100 per month.

Taxes have not been filed since Sophia started this as a hobby.
