Engagement models and project pricing

Choose a commercial structure that fits the scope, uncertainty and responsibilities of your engagement. Your proposal will explain the deliverables, pricing basis, assumptions, change process and handover terms.

How we can help

Choose a commercial structure that fits the scope, uncertainty and responsibilities of your engagement. Your proposal will explain the deliverables, pricing basis, assumptions, change process and handover terms.

Models

Five structures, chosen by how ownership actually sits.

The right model follows from who owns the outcome, how well the scope is understood, and how long the work runs — not from which structure carries the better margin for us.

01Time and materialsYou own the backlog and direction; we supply capability against it. Correct when the work is genuinely exploratory and a fixed scope would be a fiction. Priced by role and seniority, invoiced against recorded time.
  • Best when: direction will change and you want it to
  • Watch for: no natural pressure to finish — set review points
02Capped time and materialsTime and materials with an agreed ceiling and written assumptions. This can suit an initial engagement where the scope is understood but uncertainty remains. The proposal defines what the cap covers and how changes are handled.
  • Best when: scope is broadly clear but not fixed
  • Watch for: the cap must be agreed with assumptions written down
03Fixed scope, fixed priceA defined deliverable with defined acceptance criteria. Appropriate for assessments, discoveries and contained increments. Requires enough shared understanding up front to write acceptance criteria honestly.
  • Best when: the deliverable can be described precisely
  • Watch for: everything not written down becomes a change
04Outcome-linkedA portion of fee tied to an agreed, measurable result. Only offered where the measure is genuinely attributable to the work — we will decline this structure where too much of the outcome sits outside our control, because a metric neither party can influence honestly corrupts the delivery.
  • Best when: the measure is clean and both sides trust it
  • Watch for: attribution disputes — settle them before signing
05Retained capacityA named team at an agreed capacity over an agreed period, for continuous delivery or managed run. Predictable for planning; requires an honest utilisation conversation rather than a fiction that everyone is fully occupied.
  • Best when: the work is continuous rather than a project
  • Watch for: agree what happens to unused capacity
Estimating

What actually moves the number.

Your estimate reflects scope, required capability, system dependencies, access, delivery locations and the decisions needed from both teams. We document these assumptions so that any change can be discussed against the same starting point.

Agree decision turnaround and review points during scoping. If a dependency or assumption changes, assess its effect on cost, timing and scope before proceeding.

Scope

What is in the number, and what is not.

Stated explicitly because the gap between these two lists is where most commercial disputes actually originate.

Anything in the second list is either quoted separately or excluded by agreement. Neither is billed as a surprise.

  • Included: the named engagement lead's time on your engagement, at the stated commitment level.
  • Included: delivery work by the named team, governance participation, reporting, and the decision record.
  • Included: handover artefacts and knowledge transfer as defined at mobilisation.
  • Quoted separately: third-party software, cloud consumption, and licences — passed through at cost, never marked up.
  • Quoted separately: travel and on-site presence, agreed in advance rather than assumed.
  • Quoted separately: work outside agreed hours, and any support commitment beyond the stated coverage.
  • Excluded: anything not written down. This cuts both ways, and it is why we write more down than is comfortable.
Change

How change control works.

Change is normal and is not treated as a failure of planning. What matters is that it is visible and priced before it is worked, not discovered on an invoice.

  1. 01 Raised and logged

    Either party raises it. Logged with the reason and the date, whether or not it ultimately proceeds.

  2. 02 Assessed in writing

    We state the effect on cost, schedule, risk and any dependent work — including where the effect is nil, which is common and worth recording.

  3. 03 Accepted before work starts

    No work is performed against an unaccepted change. If it is urgent, we agree a bounded amount of investigative effort explicitly rather than proceeding on assumption.

  4. 04 Reflected in the plan

    The plan, the estimate and the acceptance criteria are updated together, so the current position is always one document rather than an original plus a pile of amendments.

Your protections

Terms that exist to limit your exposure to us.

These matter more than usual when a supplier is new and unproven. They are offered because we would want them if the positions were reversed.

Ask for each of these explicitly. A supplier's willingness to commit to them tells you a great deal about how the relationship will behave under strain.

  • A bounded first engagement, so the cost of being wrong about us is known in advance.
  • A cap on time-and-materials exposure, with the underlying assumptions written down alongside it.
  • Defined exit terms with a notice period and a specified handover package, agreed at the start.
  • Client ownership of deliverables, documentation and the decision record — during the engagement, not on final payment.
  • No deliberate lock-in: no undocumented dependency, no withheld credentials, no proprietary wrapper around your own systems.
  • Pass-through costs at cost, evidenced.
  • Written notice and a proposed named replacement if the engagement lead changes, subject to your acceptance.
Common questions

Questions worth settling before signing.

Why not publish a rate card?

Because a rate divorced from the work is not comparable between suppliers and is routinely used to win on price before recovering margin through scope disputes. Two firms quoting the same daily rate can differ by a factor of two in delivered cost.

You will receive rates itemised by role and seniority in your proposal, alongside the assumptions and the estimating basis, so the number can be interrogated rather than merely compared.

Are you cheaper than a large integrator?

Often on total delivered cost, because senior-weighted teams need fewer people and less rework, and because our overhead is a fraction of a global firm's. Not always on headline rate, since we are not staffing your programme with a junior pyramid.

If your evaluation is decided purely on lowest day rate, we will probably lose it, and that is a rational outcome for both of us.

What currency and contracting entity?

Contracting is through MENTARA GLOBAL TECHNOLOGIES PRIVATE LIMITED, registered in India. Invoicing currency, applicable taxes and any withholding obligations depend on your jurisdiction and are confirmed in the proposal rather than assumed.

For workforce engagements specifically, employment classification, right-to-work verification and any local statutory obligations are addressed per market — the arrangement that is correct in India is not the one that is correct in the UK or the US.

Do you require a minimum engagement size?

No. We would rather start with a two-week assessment that goes well than a two-quarter programme neither party has earned yet.
