Integrating your ecommerce with your ERP: where to start
Most failed integrations don't fail because of the technology — they fail because they start from the wrong side of the problem.

As an online store grows, at some point manually updating stock and prices stops being enough. That's when the idea of "integrating the ecommerce with the ERP" shows up, as if it were a single project with a single scope. In practice, it isn't: there are several possible integrations, and each one solves a different problem.
The first question isn't technical, it's about the business: what breaks most often today? For some companies it's stock (selling something they no longer have), for others it's pricing (the store shows an outdated list), and for others it's invoicing (everything gets entered twice). Starting there, instead of "integrating everything," defines a scoped project that can be finished in weeks, not months.
Once the scope is defined, it's worth deciding the direction of the data: does the ERP hold the source of truth and the ecommerce just reflects it, or are there cases where the ecommerce also writes back? Getting this confused causes the hardest bugs to diagnose: two systems arguing over who's right about the same piece of data.
Only once scope and direction are clear does it make sense to talk about the technical side: the ERP's API, the ecommerce's webhooks, sync frequency, error handling when something fails halfway through. The technology to solve this already exists and is fairly standard — what decides whether the project goes well is having first understood which real process is actually being connected.
