Why InfoTrack
Senior review on every change
Every change is reviewed by a senior engineer before it reaches production.
Predictable scope
Deliverables, exclusions and acceptance criteria are written down before work starts, so everyone knows what done means.
No hourly billing
You buy an outcome at a set price. Time we spend fixing our own estimation mistakes is our cost, not yours.
Controlled AI use
We use AI-assisted tools to move faster, only where your agreement allows, and a person signs off on every line that ships.
Michel Carrelo
Founder and lead engineer
Twenty years of engineering in systems and telecommunications, including fleet telematics, payment platforms and hotel software. Michel scopes every project, reviews every release and is the person you talk to from the first call to launch.
Questions buyers ask
Do you use AI to write code?
Yes. We use professional AI-assisted engineering tools where appropriate to speed up development, testing and documentation. Every production change is reviewed by an experienced engineer, and your code or confidential data is only processed with tools permitted by the project agreement.
Who owns the code?
You do. The repository sits in your account from day one, and full intellectual property transfers to you on final payment under the contract.
What happens if we want to change the scope?
Tell us early. We write up the change, price it and agree a new date with you before building it. If the agreed scope stays the same, the price stays the same.
What does the 30-day warranty cover?
Any defect in the agreed scope, meaning behaviour that does not match the statement of work or its acceptance criteria. New features and changes to a workflow are change requests, priced separately or handled through the subscription.
Can you host and maintain the software?
Yes. We can deploy to your own cloud account or manage infrastructure for you as part of the subscription. Hosting and other third-party usage are billed separately from development.
How do payments work?
Smaller projects are paid 50% at the start and 50% before final delivery. Larger projects are paid 40% at the start, 30% at an agreed milestone and 30% on delivery. Long projects can be split into monthly milestones.
Do you work with agencies?
Yes. Design agencies, consultancies and integrators bring us in as their engineering partner for fixed-scope projects, under their brand or ours.
Discuss your project
Tell us what you need in a few lines. We will reply by email to set up a 20-minute fit call, and you will speak with the engineer who would lead the work.
