Thirdly, scale all aspects of your business as you grow. What might be reasonable and practical for a small seller, may be impossible for a big seller to do. As sellers sell more, often their time, resources and attention becomes split between more and more brands, products and tasks. Accounting, auditing, procedure and policy need to grow in their breadth, depth and intricacy as a seller gets bigger – but far too often they are not scaled at the same rate as the marketing or warehouse staff. To maintain growth, you can’t cut corners, but need to build sustainably.
