Multimax
A delivery integration for Multimax, syncing checkout orders straight into a fulfilment provider that had no WooCommerce presence of its own.
Multimax was another WooCommerce store where I worked as the sole freelance developer, the same shape of engagement as the rest of that three-year stretch: gather the requirement, choose the approach, deploy it, then support it.
Why the integration had to be written at all
The store's fulfilment ran through a delivery provider whose systems had no WooCommerce presence, so orders had to reach it straight from the checkout without someone retyping them into another window every morning. WooCommerce had no plugin for this specific provider, so I built the sync myself: a custom integration that pushed each order out automatically as it came in.
An integration like this is the unglamorous category of work that decides whether an online store functions as a business rather than as a catalog. Orders that do not reach fulfilment automatically are a person doing data entry until they make a mistake.
The part that generalizes
Same lesson as everywhere else in that freelance stretch: everything I shipped, I was going to be the one supporting it, which is a fast way to learn that clever is expensive and boring is cheap.
A note on detail
The integration code belongs to the client, so there is no repository to link. If you want the specifics of how the delivery sync handled failures, ask me and I will walk you through it properly.
