Guillermo LizasoainPayments Delivery Executive & Operator

Services

Outcome-based engagements, not open-ended consulting.

I structure engagements around clear findings, practical fixes, and tools your team can keep using after I leave.

Payments Delivery Diagnostic

I trace how transactions, integrations, processor dependencies, settlement, reporting, and support escalations actually move through the business, then turn the findings into practical outputs your team can use.

Example outputs

  • Delivery friction points
  • Payment lifecycle map
  • Processor and integration dependencies
  • Reporting and visibility gaps
  • Fix-first action plan
  • Executive readout

Roadmap Execution Support

I help leadership and delivery teams decide what to fix first, who owns it, and how progress will be measured.

Example outputs

  • First-priority fixes
  • Roadmap sequencing
  • Decision and ownership map
  • Delivery review cadence
  • Progress checkpoints
  • Leadership readout

Sales Engineering Enablement

I help sales, product, implementation, and engineering teams understand what a payment solution actually requires before it is promised to a customer.

Example outputs

  • Discovery checklist
  • Scoping model
  • Payment flow training
  • Technical objection guide
  • Requirements handoff template
  • Implementation readiness checklist

Operating Model Implementation

I help clarify who owns what, where work gets handed off, and how issues move from sales through implementation, support, risk, operations, product, and engineering.

Example outputs

  • Ownership map
  • Handoff map
  • Escalation path
  • Feedback loops between teams
  • Team playbooks
  • Role clarity notes

AI-Assisted Delivery Enablement

I help teams use AI tools in real delivery work without losing review discipline, ownership, or production quality.

Example outputs

  • AI usage rules
  • Coding agent and LLM workflow
  • Review checklist
  • Team training
  • Risk controls
  • Pilot plan

Advisory Continuity

I stay close to the roadmap after the initial work, helping leadership review progress, make tradeoffs, and handle new constraints.

Example outputs

  • Monthly progress review
  • Roadmap review
  • Leadership guidance
  • Architecture decision support
  • Team-shape guidance
  • Support for important client or partner opportunities

Engagement path

Start with clarity. Stay through execution.

Most engagements begin with a focused diagnostic because payment delivery problems rarely break in only one place. I map the real flow, identify the constraint, and define the practical path forward. From there, I can help your team execute the roadmap, strengthen the operating model, enable the people responsible for delivery, and sustain the change as the business scales.

  1. Diagnose

    Map the payment delivery system, surface the hidden handoffs, and identify the real constraint.

  2. Blueprint

    Define the roadmap, source-of-truth model, observability gaps, implementation standards, and operating priorities.

  3. Execute

    I help your team turn the roadmap into working change, focusing first on the fixes that reduce rework, delays, and recurring escalations.

  4. Enable

    Equip sales, product, implementation, support, and engineering teams to scope, communicate, and operate from the same delivery model.

  5. Sustain

    Provide advisory continuity, operating reviews, and leadership guidance as the roadmap matures and new constraints appear.

Engagement phases in detail

The diagnostic is the front door. These phases show how I can help once the team knows what needs to change first.

Payments Delivery Diagnostic

4 weeks

Find the real constraint and define the path forward.

I map how payment work moves through the company, identify where delivery is breaking down, and turn that into a practical roadmap.

Best for: Companies that need clarity before committing to a larger change effort.

  • Where delivery is breaking
  • Transaction lifecycle map
  • Reporting and visibility gaps
  • Integration and implementation gaps
  • Fix-first roadmap
  • Executive readout

Roadmap Execution Support

Move from diagnosis to execution without losing the thread.

I help your team turn the roadmap into real improvements, starting with the fixes that remove the most friction.

  • Implementation priorities
  • Work ownership
  • Architecture and delivery plan review
  • Review cadence
  • Progress checkpoints
  • Leadership readout

Operating Model Implementation

Clarify ownership, handoffs, and feedback loops so the platform can scale.

For companies where the real bottleneck is not the technology alone, but who owns the work and how it moves between teams.

  • Ownership map across sales, product, engineering, operations, risk, implementation, and support
  • Sales engineering workflows
  • Requirements handoff standards
  • Implementation readiness standards
  • Escalation paths and feedback loops
  • Team playbooks

Sales Engineering and Team Enablement

I help teams scope payment work clearly before it becomes delivery risk.

I help the people selling, scoping, and delivering complex payment work set clearer expectations and reduce handoff friction.

  • Payment flow training
  • Merchant discovery and scoping workshops
  • Technical objection handling
  • Integration architecture reviews
  • Sales-to-product requirements templates
  • Implementation readiness checklists

Advisory Continuity

Keep momentum as the team works through the roadmap.

I stay involved in a limited advisory role to help leadership review progress, adjust priorities, and handle new constraints.

  • Monthly progress review
  • Roadmap progress review
  • Leadership guidance
  • Architecture and ownership guidance
  • Support for key client or partner opportunities
  • Hiring and team-shape guidance

Fit

Where I add the most value — and where I don't.

Good engagements start with being honest about fit. Here's where I'm most useful — and the situations where I'm probably not the right call, so there's no wasted time on either side.

Good fit

  • Payments companies, fintech platforms, and payment hardware companies
  • ISOs, PSPs, PayFacs, and software platforms adding payments
  • Merchants with complex payment needs — multi-processor, cross-border, or high-volume
  • Teams where sales is outpacing implementation capacity
  • Companies with recurring integration escalations
  • Leadership that needs clarity before a larger transformation commitment

Usually not a fit

  • Generic interim CTO coverage without mandate
  • Engineering staff augmentation or open-ended hourly work
  • Roles that want senior credibility without diagnosis or change
  • Buyers looking for placeholder executive coverage

Frequently asked questions

What does a Payments Delivery Diagnostic include?
A focused review of how payment work actually moves: transaction flow, integrations, processor and hardware dependencies, settlement, reporting, support escalations, and the handoffs that slow delivery. It ends with a fix-first action plan.
Is the diagnostic the whole engagement?
No. The diagnostic is usually the starting point. Once the roadmap is clear, I can help your team execute the first fixes, clarify ownership, improve handoffs, enable sales and delivery teams, or stay involved as an advisor.
Who is this for?
Payments companies, fintech platforms, payment hardware companies, ISOs, PSPs, PayFacs, and software platforms whose payment delivery systems have become difficult to scale.
Is this staff augmentation?
No. I structure the work around a clear problem, a defined set of outputs, and practical tools your team can keep using. It is not open-ended hourly staff augmentation.
How is this different from fractional CTO work?
Fractional CTO work often implies ongoing leadership coverage. My work is more focused: I diagnose where delivery is breaking, define what to fix first, help the team execute, and leave behind clearer ownership and better ways of working.
Do you work only in payments?
I work primarily in payments, but the operating model also applies to complex platform, integration, data, workflow, and delivery problems.
Can you help with AI-assisted engineering adoption?
Yes. I can help teams adopt AI-assisted workflows using clear rules, developer accountability, review discipline, and production-quality controls — grounded in live practice, not experimentation theater.
