I would separate quoted supply from estimated work and unknown work. Same carton range, presentation task and handover scope for each offer. Otherwise the cheapest column may simply contain the most blank cells.
Who's doing the presentation work in the lower offer? A supplier can legitimately leave work to you, but it still takes somebody's time and fixtures. I'd want that visible before asking them to sharpen an arm price.
Fiona's point can change running cost as well as installation cost. Keep the work frequency beside it. A customer-supplied fixture is not the same exclusion as a person continuously feeding prepared cartons.
Priya, does training cover your actual operators and changeovers, or a single demonstration for whoever attends? I've had to budget another session once we named the evening staff who would use the equipment.
Do not label that guarding line included until the assessed arrangement and supplying party agree. A provisional allowance can be visible without pretending it is a quote.
Has the ranking changed, Priya? Interested whether the original price gap survived the added work. Even an incomplete comparison should now explain why one total remains less certain than another.
