One price, one dropdown, one stock number
Every product forced into the same shape, regardless of how many real variants it actually has.
ECOMMERCE · CUSTOM CHECKOUT
Stock tracked per variant, not behind one shared number
A generic cart plugin assumes every product has the same shape: one price, maybe one dropdown. A custom checkout is built around what is actually being sold, so a fragrance with twelve size and concentration variants tracks stock per combination, not behind one shared count that can oversell.

Each size, concentration or colour combination carries its own count, so what is shown as available actually is.

Included in every build, not priced separately
Custom checkout is part of every ecommerce build in this category, not billed as an add-on discovered mid-project. Payment processing runs on Stripe by default. What is genuinely custom is the catalogue and cart logic around it, built for the products actually being sold.
