We want to build a B2B ordering and dealer management platform for wholesalers selling industrial spare parts. We received proposals from two software agencies. One claimed the entire project could be built on a PHP stack, while the other insisted on using Python and the Django web app framework, citing complex database relationships and security.
The second agency quoted 380,000 TL with a 4-month delivery timeline. They mentioned their team is very confident in Python's architecture and data security. However since my technical background is limited, I have some doubts. How widespread is Django in Turkey?
If down the road we choose not to renew our maintenance retainer with this agency or have to part ways, will it be hard to find a freelance Django developer or another agency? What delivery terms should I put in the contract so we don't end up locked in?
