We are a small business producing natural olive oil and regional soaps. Up until now, we've only been selling to friends and family or through social media DMs via wire transfer. We now want to build a fully compliant registered e-commerce site that issues proper invoices. We have about 35 different product SKUs ready to sell. The total seed money we have set aside for this is around 60,000 TL.
Researching this online I've run into two completely different schools of thought. Some people I know claim I can easily launch my own site within a week using open-source platforms. Others insist I absolutely must work with an e-commerce agency, warning that I'll hit a brick wall dealing with virtual POS, automated invoicing, and shipping integrations on my own. Our company entity and tax registration certificate are all set and ready.
What are the step-by-step technical and administrative requirements for building an e-commerce website from buying a domain to shipping the first order? Can I manage this entire workflow solo with a 60,000 TL budget, or is hiring an agency non-negotiable?
