How do companies choose between using outside services to enable dropshipping and bringing logistics in house?

I eventually ran out of resources managing packing, labeling, and returns when I owned my own online store. At that point, I came across repackingplus and realized that using a 3PL dropship strategy might reduce logistical complexity without compromising customer satisfaction. According to the experiences I've observed, outsourcing turns from a convenience to a strategic tool when growing SKUs and geographic reach make in house fulfillment a bottleneck.
