We decided to launch a digital sales channel for our family business, which focuses on home textiles and custom-made curtains. A local digital agency we met with quoted us a project and setup fee of 140,000 TL, saying they would develop "custom e-commerce software" for us. Looking online, though, I see ready-made e-commerce packages or open-source systems going for 15,000 to 25,000 TL a year.
What exactly does "e-commerce software" in this quote entail, and how does it differ from turnkey rented cloud platforms? They claim they'll write custom code from scratch, but does building a system from the ground up make sense for such a standard need? If we stop working with this agency down the road, will we be left stranded? Would off-the-shelf platforms fall short because we have our own fabric and measurement options, or are we paying a huge premium for nothing?
