The chemical sales cycle is a laboratory cycle wearing a commercial coat
Nothing in this business is bought on a quote alone. A buyer wants a grade that performs in their process, so the real sequence is enquiry, specification, sample, plant trial, trial result, commercial negotiation, first order, and only then a repeat rhythm. The commercial team controls perhaps three of those steps. The rest happen inside somebody else's factory, on somebody else's schedule.
That is precisely why the pipeline needs to be tracked more carefully here than in most industries. When the critical stage happens where you cannot see it, the only protection is a record of what was sent, when, to whom, and what was promised in return.
