Separating business cash from household money
Cash in hand is not profit. Set yourself a pay and take it out of the till as a declared expense.
Braids in Bandal: collecting 40,000 CDF does not mean 40,000 CDF to spend at home.
Recording a deposit without double-counting revenue
The sale is counted once. The deposit and the balance are two payments linked to the same sale.
40,000 CDF agreed, 10,000 CDF deposit: the client still owes 30,000 CDF. The balance is not a new sale.
CDF, USD and EUR: three separate tills
Never add different currencies together. An exchange rate is only indicative.
B2B consulting in Lubumbashi: a 1,500 USD assignment stays in USD, next to your CDF sales.
Contribution margin of a service
Margin = agreed price − direct costs. Before fixed costs and paying yourself.
40,000 CDF − 9,000 CDF (5,000 transport + 4,000 hair extensions) = 31,000 CDF margin.
Gross margin of a shop
Only the cost of items sold is deducted. Remaining stock keeps its purchase value.
Wax prints: 3 sold at 8,000 CDF = 24,000 CDF; cost 15,000 CDF; margin 9,000 CDF; 7 in stock (35,000 CDF).
Receivable
What the client still owes: agreed price minus what was collected. Never negative.
Fitness coaching in Gombe: 350 USD, 175 USD deposit, 175 USD receivable.
Cost of goods sold (COGS)
The cost of what is sold, recorded at the time of sale, not purchase.
Mikate: batch of 10 for 6,000 CDF, 600 CDF each; 4 sold, COGS 2,400 CDF.
