We run an e-commerce store selling custom ceramics in the US market. Our monthly ad spend is around $4,500. Over the past six months, conversion data inside ad platform dashboards has started drifting significantly; the order counts in the dashboards don't match the actual orders in our store admin. They're telling us we're losing nearly a third of our order data due to browser privacy updates and ad blockers.
Our digital marketing agency says we need to switch to a server-side tracking setup to stop this data loss. However, they quoted us a $1,500 one-time setup fee, plus roughly $120 to $150 per month in ongoing cloud server and middleware maintenance costs.
Are these kinds of infrastructure costs really necessary for a small business doing $20,000 in monthly revenue? What tools or approaches can we use to set up server-side data tracking on a reasonable budget that still covers the essentials?
