Expanding the business into new territories brings you new customers, with their new money, - sadly sometimes together some new challenges. While you were only serving your initial target audience, your operations were most likely designed in a "quick and dirty" fashion, which is absolutely reasonable for the initial business establishment phase. Or, you might have even designed your business operations, systems and processes in a very clear (and probably even documented!) manner – you just did it for your initial purpose, rarely with potential expansion in mind, simply because it was not justified at the time when you were starting the business.

But when you want to invest – or asking someone else to invest – additional resources into your business expansion it might be useful to look into
(1) your business operations and check
(2) how scalable they are.
Check (3) if order placement process is automated enough to sustain your expected increase in customers,
(4) if your processes are logical enough for all these new employees you are about to bring onboard, and
(5) if they ensure the segregation of duties requested by authorities. Convince yourself – and your potential investors – that your business operations are essentially mature enough to get to the next level with controllable risks.
