designing for multi-country, multi-currency from day one

if you build a single-country storefront and try to bolt on multi-country later, you'll regret it. here's the data model decisions that scale.

introduction

this is a sample blog post in the Okommerce content system. The actual content will be written by the Royex content team and replaces this placeholder.

each post follows the same structure: a hook, the problem we're addressing, the approach we took, what worked, what didn't, and what we'd do differently. concrete code, concrete numbers, no marketing fluff.

the problem

describe the specific challenge being addressed. what made it hard? what made existing solutions inadequate? quantify wherever possible.

our approach

walk through the solution step by step. include code samples where relevant:

// Example: scope-aware query
public IQueryable<Order> GetOrdersInScope(User user)
{
    return _db.Orders.Where(o => o.BranchId == user.BranchId);
}

what we learned

be honest. include the things that didn't work. include the surprises. include the second-order effects you didn't anticipate.

what's next

where this thread continues. what we're working on next. what we'd love to hear from readers.
