The commercial structure of a technology implementation engagement is typically one of two models — or a hybrid of both. Under time and materials (T&M), the client pays for the implementation partner’s actual time consumed and resources deployed, at agreed day rates or resource rates. The total cost is variable: if the engagement takes longer than estimated, the client pays more. Under fixed price, the client pays a defined amount for a defined scope of deliverables, regardless of how much effort the partner must invest to deliver them. The scope is fixed; the cost is fixed; the partner bears the risk if the engagement takes longer than estimated. The choice between these models determines where the delivery risk sits — with the client (T&M) or with the partner (fixed price) — and the implications of that risk allocation run through every aspect of programme governance.
Why This Matters in GCC and Egyptian Enterprise Programmes
The balance between T&M and fixed price is a particularly important decision in GCC implementations where scope definition at programme initiation is genuinely difficult. In group structures where the consolidation perimeter is not fully defined at programme start, where subsidiary data quality is unknown, or where regulatory requirements in multiple jurisdictions may change during implementation, a fixed-price contract locks the scope at a point when the scope is not fully known. The partner prices for the worst-case scenario; the client pays the worst-case price for a best-case outcome. In these environments, a T&M model — with robust scope management and strong governance — frequently produces a better commercial outcome than a fixed-price model that prices in uncertainty the client ends up not encountering.
What Good Looks Like
Commercial model selection should be driven by scope certainty, not by commercial preference. Where requirements are fully defined, business processes are stable, and the organisation has the governance to control scope: fixed price is appropriate. Where requirements are partially defined, data quality is unknown, or the implementation involves genuine technical risk that the scope cannot fully capture at the outset: T&M with governance is a more honest commercial arrangement. A hybrid approach — fixed price for defined deliverables, T&M for residual advisory and support work — is often the most practical model for complex implementations.
What Organisations Get Wrong
The failure that most frequently converts a fixed-price engagement into a disputed contract is the client seeking fixed-price certainty before the scope is sufficiently defined to support fixed-price pricing. The partner provides a fixed price based on assumptions about scope and data quality that are specified in the contract. When the scope is larger or the data quality worse than assumed, the partner invokes the scope boundary to decline additional work. The client is surprised, because the sales conversation implied the contract covered what they needed. The gap between what was assumed and what was contracted is the source of the dispute — and it was created by the pressure to get to a fixed price before the scope was genuinely fixed.
How Loop Wise Solutions Approaches This
We advise clients on commercial model selection as part of the RFP design process — recommending the model that reflects the scope certainty at the point of contracting. Where scope is not yet fully defined, we recommend a T&M or hybrid model with defined governance, rather than a fixed-price model that prices an underdefined scope and creates contractual risk for both parties. We also review the scope assumptions embedded in fixed-price proposals — identifying assumptions that are likely to be breached and the contract terms that govern what happens when they are.
