Our Commitment

Fixed date. Fixed fee. Customer-signed acceptance.

These aren't marketing promises. They're the standards we hold ourselves accountable to on every engagement. Our reputation depends on it.

01

Production-Grade or Nothing

Every line of code we write is built to run in production. We don't do throwaway prototypes or proof-of-concepts that can't scale.
  • Infrastructure as Code from day one
  • Comprehensive testing and observability
  • Security and compliance built-in
  • Documentation that enables your team

02

Deadlines Are Sacred

When we commit to a date, we deliver. Our track record speaks for itself: 94% of projects delivered on or ahead of schedule.
  • Realistic scoping and estimation
  • Proactive risk identification
  • Transparent progress reporting
  • Scope management, not scope creep

03

Your Team Gets Stronger

We succeed when you no longer need us. Knowledge transfer and capability building are embedded in every engagement.
  • Pair programming and code reviews
  • Architecture decision records
  • Runbooks and operational documentation
  • Training and enablement sessions

04

Honest Counsel Always

We'll tell you when your approach won't work, when the timeline is unrealistic, or when there's a better path. Even if it means less work for us.
  • No-BS technical assessments
  • Clear trade-off analysis
  • Challenge assumptions constructively
  • Recommend alternatives when appropriate

Let's talk about what you need and how we can deliver it : with these commitments as our contract.

Our Commitment: Fixed Date, Fixed Fee, Signed Acceptance

  • Ship date in the contract
  • Fee fixed before build
  • Overage absorbed on our delay
  • Legacy retired as a deliverable
  • Five signed phase exits

Four things go into the statement of work before any build starts: the scope, the ship date, the total fee, and who carries the cost if that date moves. This page is what each of them says, and what happens when one of them is tested.

The terms below are the standard ones. They are shared in full during commercial discussions, and the signed statement of work governs in every case.

Read it before you scope it

The clause that carries the date is available before any conversation about scope.

Thirty minutes with the forward-deployed engineer who would sign for your engagement.

What Does Mactores Actually Commit To?

Four terms, all four written down before build begins. Each one is stated below in the form it takes in the statement of work, along with what it means for the person who has to plan around it.

  1. 01

    The ship date is named in the contract

    A single date, not a range and not a target quarter revisited at each steering committee. Scoping produces the date, and the date goes into the signed statement of work alongside the scope it belongs to.

    What that means for you

    A date your finance team can budget against and your board can be told.

  2. 02

    The fee is fixed before the build starts

    The total is set once scope is confirmed at the end of phase 01, and it is fixed against that scope. A later change to the scope is a change order with its own price and its own signature, so the fee never drifts quietly. We will not seek further revenue from the scope of work already defined in the contract.

    What that means for you

    An invoice that matches the number you approved, or a change order you approved separately.

  3. 03

    Overage on our delay is absorbed by us

    Where the cause of a delay past the committed date sits inside Mactores' control, Mactores carries the cost of the additional work. Delays caused on your side convert to time and materials at the rate disclosed upfront in the same document.

    What that means for you

    The commitment has a consequence attached, and the consequence is ours.

  4. 04

    The legacy estate is retired as a deliverable

    Decommissioning the system you are replacing is written into the scope, along with the licences and infrastructure attached to it. An engagement that leaves the old system running has moved a cost rather than removed one.

    What that means for you

    The saving shows up in next year's run rate, not just in the architecture diagram.

Check the wording against your own

Ask whoever else is bidding to show you the same four terms in writing.

Fixed fee means different things in different proposals. The difference is usually in the delay clause.

Why Can Mactores Afford to Sign That?

A fixed date is only honest if the delivery model can carry it. Three properties make these terms affordable to offer, and all three are structural rather than a matter of effort.

01

Automation absorbs scale

Roughly 60 to 70 percent of the hours a traditional consulting proposal of the same size would staff for.

Share of hours on a comparable proposal

Discovery, dependency mapping, schema analysis, harness generation and documentation run as machine work. Those hours are not removed from the estimate by optimism; they are not in the estimate at all.

02

Engineers absorb judgment

Every engagement is staffed with senior forward-deployed engineers rather than a pyramid.

Architecture, sequencing, exception handling and the cutover decision stay with named people who are in your environment for the duration. The engineer who scopes the work signs for the date, which removes the gap between the team that sells and the team that delivers.

03

The contract absorbs risk

The delay clause moves the commercial risk of our own slippage onto us.

That is only possible on top of the first two properties. A firm billing by the hour has no reason to carry it, and a firm without senior staffing on every engagement has no way to price it.

What Do You Sign, Phase by Phase?

Five phases, each closing on a named exit that needs your signature before the next one opens. A phase that cannot close is visible while there is still budget and schedule left to respond to it, which is the point of gating the work this way rather than reporting on it monthly.

  1. 01

    Assess

    Current state analysed across the applications, data and dependencies in scope. A roadmap is delivered that names what moves, what is replaced, what is retired, and what we recommend you leave where it is.

    Exit

    Roadmap signed

  2. 02

    Design

    Target architecture chosen and the trade-offs documented in writing. Commercials are locked here, which is the point at which the date and the fee become contract terms rather than estimates.

    Exit

    Statement of work countersigned

  3. 03

    Build

    Implementation against the approved architecture, with regression tests generated continuously as the code changes rather than written once at the end.

    Exit

    Build complete

  4. 04

    Test

    Validation runs in parallel with the legacy system, and where regulators require it the audit evidence is captured by the validation work itself.

    Exit

    Acceptance gate passed

  5. 05

    Deploy and operate

    Production cutover, rehearsed before it is executed, with rollback criteria agreed in advance. The legacy environment is decommissioned.

    Exit

    Acceptance signed

What Backs the Commitment After Delivery?

Three standing terms sit behind the signature, and all three run past the moment the system goes live. A commitment that stops at handover asks the customer to carry everything that happens next.

Satisfaction guarantee, first thirty days

Raise it early and we correct the work at our cost or credit the period.

The window sits at the start of an engagement on purpose, so a concern about the standard of the work is raised while there is still time and budget to act on it.

Fixed price on a defined scope

Available on any scope defined well enough to price.

It moves the timeline and budget risk on that scope onto us. Scoping is a phase with a signed exit rather than a pre-sales exercise, which is what makes the price possible to hold.

Ninety-day warranty on what we built

Defects found in production inside ninety days of acceptance, fixed at no cost.

Handover is inside the scope for the same reason: runbooks, architecture decision records and enablement sessions ship with the system, because a warranty matters less than a team that can operate what it was given.

Your signed statement of work governs in every case, and its wording prevails over this page.

The guarantee is in the document

Ask to see the delay clause and the warranty wording before you scope anything.

Both are standard terms, and both are shared in full during commercial discussions.

What Evidence Does the Work Leave for Your Auditor?

Each of the five phase exits produces a document, and in a regulated environment those documents are the evidence set your reviewer asks to see. They are generated by the delivery work rather than compiled afterwards, so there is no separate compliance workstream to fund. Designing against a framework is not the same as certifying you to it, and the certification stays yours and your auditor's.

  • U.S. Securities and Exchange Commission, a framework Mactores designs delivery work against
  • HIPAA, a framework Mactores designs delivery work against
  • FFIEC, a framework Mactores designs delivery work against
  • GDPR, a framework Mactores designs delivery work against

Which phase exit produces which artefact

Artefact Produced at What a reviewer uses it for
Signed roadmap and scope Phase 01 Establishing what was in scope and who agreed to it, which is where a scope question usually starts
Customer-signed acceptance record Every phase Showing that changes were authorised by someone with the authority to authorise them
Reconciliation output with variances explained Phase 04 Tracing an output in the new system back to the system of record it came from
Cutover runbook and rehearsal results Phase 05 Demonstrating that the change was planned, rehearsed and reversible
Decommission record Phase 05 Confirming what was switched off and where the data on it went

Marks appear as published by each body and are not recoloured. PCI DSS and SOC 2 are named in type across this site: PCI SSC issues no compliance logo and prohibits marks implying compliance, and the AICPA licenses its mark only to organisations holding their own unqualified report. Naming a standard indicates what the delivery work is designed against, and not endorsement or certification by that body.

Frequently Asked Questions

What happens if Mactores misses the committed date?

Mactores carries the cost of the extra work needed to land it. There is no argument after the event about whose fault it was, because control is defined at signature and each phase exit records what was agreed on the way through. You see the wording before you sign, not after.

What counts as a customer-caused delay?

The categories are named in the statement of work rather than left to interpretation: access to environments and data, availability of your named approvers at a phase exit, and decisions that sit with your side. Each one converts to time and materials at a rate disclosed in the same document, so the commercial effect is visible before you sign.

Is the fee genuinely fixed, or does a scope change reprice it?

Fixed against the scope confirmed at the end of phase 01. Work outside that scope is a change order with its own price and its own signature, which means the original number cannot quietly absorb new work and the total cannot move without you agreeing to it in writing.

How does the satisfaction guarantee work?

It runs for the first thirty days. Raise a concern about the standard of the work inside that window and we either correct it at our cost or credit the period. The window is deliberately at the start, while there is still schedule and budget left to act on what you raise.

What does the ninety-day warranty cover?

Defects in what we built, found in production within ninety days of acceptance, fixed at no cost to you. It sits alongside handover rather than instead of it, because runbooks, architecture decision records and enablement sessions ship with the system so your team can operate it without us.
