Category: Oil & Gas Companies Published: September 13, 2026 Source: https://www.vendoreye.ae/blog/setting-oil-and-gas-supplier-delivery-milestones Supplier milestones should reflect meaningful progress toward an accepted oil and gas package, not only calendar dates or invoice events. Technical submissions, manufacture, mobilisation and final records may each have different review conditions. Build the milestone schedule with competent project teams so commercial reporting does not imply readiness that engineering, quality or the operator has not confirmed. ## Define the evidence for each milestone State the deliverable, responsible reviewer, required record and acceptance condition. Distinguish submission from approval, dispatch from receipt and task completion from final acceptance. These events may occur at different times and should not be merged simply to make the schedule shorter. For example, a drawing sent for review is not necessarily permission to manufacture. The project should identify the agreed gate and its owner. Procurement can track the status, but qualified technical personnel determine whether the submission satisfies the relevant requirement. ## Make buyer dependencies visible Identify information, access and decisions the buyer or operator must provide. Agree how late or changed inputs affect the schedule and how the supplier reports the consequence. Preserve the original baseline and approved revisions rather than moving dates informally after a delay. For a service package, clarify resource readiness and mobilisation conditions through the appropriate site process. A supplier should not be marked fully ready solely because personnel are available if other operator-controlled requirements remain unresolved. ## Control deviations and recovery plans Ask the supplier to report a missed milestone with cause, affected dependencies and a credible proposed plan. Have qualified teams review technical or safety implications. Commercial urgency should not encourage unapproved substitutions or bypassed inspection and authorisation stages. Review upstream commitments where the supplier relies on another manufacturer or specialist. A recovery statement should explain what the responsible source has confirmed, not merely repeat the distributor's intention to expedite. ## Use milestones for decisions, not decoration Link the project review to accepted evidence, open conditions and authorised commercial consequences. Have appropriate advisers assess payment and remedy terms for the agreement. Analyse recurring issues in documentation, source control or buyer inputs and correct the process. A good milestone system gives the project an honest readiness picture while preserving the distinction between a reported activity and an equipment or service package that has actually met its required acceptance conditions. ## Related buying guides - [Testing an oil and gas supplier before wider mobilisation](/blog/testing-an-oil-and-gas-supplier-before-wider-mobilisation)- [Budgeting oil and gas procurement beyond purchase price](/blog/budgeting-oil-and-gas-procurement-beyond-purchase-price)- [How to choose oil and gas suppliers in the UAE](/blog/how-to-choose-oil-and-gas-suppliers-in-the-uae)[Browse all Oil & Gas Companies guides](/blog?category=Oil%20%26%20Gas%20Companies).
