Frequently asked questions
What are fixed and variable costs?
Fixed costs stay the same regardless of sales (rent, salaries, software). Variable costs rise with each unit sold (materials, delivery, payment fees).
Should I include GST?
Use prices and costs excluding GST, because GST you collect is paid to the government (net of input credits).
