You can sell IT services worth several million dollars on Instagram too. Many see Instagram only as a channel for cheap, mass products — that view is limiting.
The process decides, not the ticket
The idea that an expensive IT service can't be sold on Instagram is the fault of the process, not the channel. With a well-built funnel (substantive video, trust, qualified leads, the right sales process), Instagram carries big tickets too.
The key is adapting the audience and offer to the ticket: a million-dollar service isn't sold with a 15-second creative — it needs its own content and process.
Conclusion
Don't limit the channel — build the process right. Instagram works both for a cheap product and for a million-dollar IT service; only the approach differs.
