According to Forrester Research forecasts, more than 50% of large cross-border transactions will be completed directly through manufacturers' own websites or self-service portals by 2025—this trend is already happening. The key is not whether buyers have someone accompanying them, but whether the system can provide sufficient "certainty." Quotation conditions must be clear, versions recorded, and confirmations documented. If inquiries, quotations, POs, and PIs can all be managed in one place, with diff views for each modification and version records for each submission, procurement managers won't need sales help to "confirm," and even large orders can be placed online with confidence. This isn't a tech gimmick; it's practical engineering to reduce friction and build trust.
