Custom Application & API Engineering

Server-side development in PHP and Laravel that connects secure payments, licensing forms and OPRA records requests to your systems.

Connect with us today

Public sector applications carry obligations most commercial software doesn't: payment data has to be PCI-scoped, licensing submissions need an audit trail, and records requests have to be fulfilled correctly under OPRA. We build custom applications and APIs on PHP and Laravel specifically for that environment, integrating secure payment processing, licensing and permit workflows, and records-request handling into systems your staff can operate confidently.

What this covers

Custom Laravel applications and REST APIs, secure payment integrations (Stripe and similar PCI-scoped providers), licensing and permit form engineering, and OPRA records-request workflows with a documented audit trail.

Integrations that hold up under reconciliation

An integration is not finished when the happy path works. Payments get declined, third-party services time out, and a resident closes the browser halfway through a submission. We build for those cases explicitly: idempotent requests so a retry never charges twice, queued jobs with retry and failure handling, and reconciliation records that let your finance team match what the application says against what the provider settled. When something does fail, it fails loudly into a log rather than silently into a gap.

Audit trails designed in, not added after

Traceability is a structural decision, not a feature you can retrofit once a question has already been asked. Submissions, payment events, permission changes, and record access are logged as they happen, with the actor, the timestamp, and the before-and-after state preserved. That means a compliance review, a records request, or a disputed transaction can be answered from the system itself rather than from someone's memory of what probably happened.

PCI-scoped payment integrations

Payment tooling integrated the way it needs to be for public funds: scoped, logged, and reconciled, not bolted on as an afterthought.

Licensing and permit form engineering

Multi-step licensing and permit workflows with validation, document upload, and status tracking, built around how your department actually processes applications.

OPRA-ready records workflows

Structured records handling with a full audit trail, so records requests can be located, reviewed, and fulfilled without a manual search.

Integrations built for the unhappy path

Idempotent requests, queued retries, and reconciliation records, so a timeout or a declined payment leaves a traceable state rather than a gap someone has to reconstruct by hand.

Custom Laravel Applications

Server-side applications built on PHP and Laravel, engineered for maintainability and a clear audit trail.

Secure API Integrations

REST APIs and third-party integrations built with authentication, rate limiting, and logging from day one.

PCI-Scoped Payment Tools

Payment processing integrated through providers like Stripe, scoped to keep sensitive card data off your servers.

Licensing & Permit Forms

Multi-step licensing and permit workflows with document upload, validation, and status tracking.

OPRA Records Handling

Structured records storage and retrieval workflows built to support public records request obligations.

Audit Trail By Default

Every submission, payment, and record access is logged, so accountability isn't something added after an incident.

Every integration is built with an audit trail: who submitted what, when a payment cleared, and what record was released under an OPRA request. That traceability matters as much to us as the feature working on day one.

Custom Application Api Engineering FAQs

Can you integrate a PCI-compliant payment system into our existing licensing portal?

Yes. We integrate PCI-scoped providers like Stripe so card data never touches your servers directly, while keeping full transaction records for reconciliation.

Do you build custom workflows for permit and licensing approvals?

Yes, this is a core part of the work: multi-step forms with validation, document upload, and status tracking, matched to your department's existing approval process.

How do you support OPRA records requests in a custom application?

We structure records storage with metadata and audit history built in, so a records request can be located, reviewed for exemptions, and fulfilled without a manual search.

What happens if our procurement requirements change mid-project?

Laravel applications are built modularly, so new requirements typically extend the existing structure rather than requiring a rebuild.

Do you provide documentation and an audit trail for compliance reviews?

Yes. Every application we build logs submissions, payments, and record access by default, and we provide documentation suitable for a compliance review.

Can you build an API for systems we already run, without replacing them?

Yes, and this is often the lower-risk path. We regularly put a documented, authenticated API in front of an existing system so new applications can integrate with it cleanly, leaving the system of record where it is until there is a real reason to move it.

What happens if a payment provider or third-party service goes down mid-transaction?

Requests are built to be idempotent and are queued with retry handling, so a provider outage delays a transaction rather than losing or duplicating it. The application records the attempt either way, which means the state is recoverable and reconcilable once the service returns.
