When do I need custom code instead of ready automation tools? — answered by Engineer Saeed Baatiah
Custom code is needed in four cases: when one of your systems has no ready connector for the tool, when volume grows past the point where per-step pricing makes sense, when the logic requires branching decisions that are awkward to express visually, and when the nature of the data requires it to stay inside your own infrastructure. Outside those cases, a ready tool is faster to implement and easier for your team to adjust later without you.
