Hello and welcome to JustAnswer. I am here to help you. I am reviewing your question and will respond to you shortly.
Thank you for your question..
You need to relate purchases for sales..
Please advise what is your gross margin/mark up on average?
Thank you for your reply
Based on information provided by you, it appears your gross margin is 66.8%
If one were to apply the same percentage then the gross profit will be c. £8,864 and cost of sales £4,406.
You have stated your cost of sales including opening stock is £103,506 and for last year it was £104,490.
These are too high numbers for modest sales figures you have shown.
Please check your numbers and come back .
Thank you for your reply.
