For businesses that need a procurement specialist in their corner when the decisions matter. Advise provides direct, independent advisory support with no supplier bias, no product agenda, and no obligation to any outcome other than yours.

Some purchasing decisions carry consequences that last for years. The facilities contract that locks you in for five years. The technology platform your business will depend on. The public procurement process that has to stand up to scrutiny from every direction. These are the decisions where instinct is not enough and where getting it wrong costs more than getting advice ever would. D1 Advisory's Advise services put procurement expertise alongside your decision-making at the point where it matters most. You bring the business context. We bring the procurement discipline. The result is a decision you can stand behind with confidence. Both Advise services are underpinned by our Continuous Client Capability Development (C3D) methodology. That means you do not just get an answer. You get the reasoning behind it, the frameworks that shaped it, and the confidence to apply that thinking to your next procurement decision without picking up the phone. Our goal is not to create a dependency. It is to make you a more capable buyer every time we work together.
On-call procurement expertise for the decisions that matter most. You have a question about a supplier, a contract, or a negotiation. You get in touch. We work it through together. No ongoing commitment beyond what your business activity requires.
Independent probity oversight for formal procurement processes. Probity planning, advisory, panel oversight, auditing, and reporting. Available as a standalone engagement or as part of a broader programme of work. Note: D1 Advisory cannot serve as both probity advisor and probity auditor on the same procurement activity.
When a buying decision is too large or too complex to handle alone, we step in and provide enterprise-level leadership or run the process for you. You keep control of the decision. We bring the structure, the rigour, and the supplier management so that nothing gets missed. Designed for businesses that do not need a full-time procurement function but need expert support for specific, purchases.
Every client engagement is structured around D1 Advisory's Continuous Client Capability Development (C3D) methodology. We don't just deliver procurement outcomes. We teach, partner, and hand over so your team finishes the engagement with more capability than they started with. That is the benchmark we hold ourselves to.

Quickly. The discovery call takes fifteen minutes. If the fit is right, scope and terms are agreed shortly after. The retainer is available to be activated from that point. If a specific purchasing decision is already in progress, that is a reasonable place to start the conversation.
Yes. The Advisory Retainer is particularly well suited to small and medium businesses that make significant purchasing decisions but do not have an internal procurement function to call on. Probity Services are more commonly required by government and large enterprise clients with formal public accountability obligations, but are available to any organisation that requires independent oversight of a formal procurement process.
Probity advisory involves working alongside a procurement process to ensure decisions are made fairly and in accordance with governance requirements. Probity auditing involves independently reviewing a completed process after the fact and producing a formal audit report. D1 Advisory can provide either service, but cannot serve as both probity advisor and probity auditor on the same procurement activity. This is a professional independence requirement.
An Advisory Retainer is tailored to your business activity and scaled to your engagement level. There is no one-size-fits-all arrangement because no two businesses buy the same way. The retainer gives you a direct line to procurement expertise across your buying cycle: supplier selection, negotiation positioning, contract review, and ad-hoc guidance as decisions arise. Scope and pricing are agreed at the discovery call.
