I've been doing this for many years, I went to each supplier personally for personal contact, agreed on all the conditions personally, of course, brought presents so as not to be forgotten. And ordered in advance with a margin of time, and of course checked all the terms, called myself.

Things I found helpful are 1. Have a monthly requirement and material delivery schedule 2. Have an open and transparent discussion with suppliers with material delivery schedule 3. Understand the challenges of suppliers and if they are genuine try to accommodate them with solutions 4. Negotiate for larger or overall quantity requirement to get best quote and make the suppliers agree for phase wise delivery.

Weather forecasting can be difficult but a little common sense and good communication with suppliers is essential. If you are building in a location that weather can be an issue then you must open up your schedule and allow for potential weather delays in the shipping process. It’s not rocket science, that’s why they call it construction.

To negotiate flexible delivery schedules with suppliers due to weather delays, start by acknowledging the situation and showing empathy. Clearly communicate your revised delivery needs, specifying achievable new deadlines or flexible windows. Propose solutions like staggered or partial deliveries to make the situation manageable. Explain the impact on your project timelines and stress the importance of adjusting the schedule. Be open to alternative solutions and discuss financial adjustments if needed. Finally, document the new agreement in writing to avoid misunderstandings and ensure alignment.
