Expanding to international markets is not that simple just as it sounds. There are a lot of factors to be considered. Over expansion of your business often leads to lose business into old and the existing markets itself. The markets should be categorized into four. 

1. Beachhead twins 

1. Community-powered markets 

1. Tech-savvy markets 

1. Complex markets 

When expanding to the international markets, the direct sales entrepreneurs should set practical expectations on your ROI. 
Expected-to ROI =  
(Expected Contribution in dollars × Survival curve) − (Run-rate OpEx + One-time setup) /(One-time setup + Working capital step-up) 
Expected contribution: Revenue minus the variable costs 
Survival curve: Number of customer/distributor segments you are planning to retain into the second year. 
Run-rate OpEx: Operational expenses paying for local managers, agencies, compliance, translations, privacy tools, and logistics services. 
One-time setup: Localization, payment gateway onboarding, tax IDs, product registrations, and legal checks. 
Step-up capex: Extra inventory, warehouse setup, returns station, or POS material
