We quote prices in two stages. Stage 1 is tentative while stage 2 is final.
Stage 1 : Preliminary - At this stage - you get a tentative range based on the limited information you provide. This stage occurs when you are yet to complete your product development process.
Preliminary costs are ALWAYS tentative - they give you a range or a ballpark idea of how the product costing will play out so that you can manage your production quantities vis-a-vis your allocated budget.
Once your product development is complete, we proceed to stage 2 where you get the exact product costing.
Stage 2 : If you provide all the information that is required to provide exact quotation, you skip Stage 1 above and we directly give you pricing corresponding to the products you are looking to manufacture.
If you are not sure whether you should go for Stage 2 directly, please read the answer to the question - What does a brand need to provide before you are ready to start manufacturing.
