Most businesses don't need another tool — they need the tools they already pay for to talk to each other. We design robust APIs and integrations that move data reliably between your systems, with monitoring and error handling built in.
Built by engineers who work inside your business — learning how your team works and delivering results in weeks.
How it worksSecure, versioned REST APIs with authentication, rate limiting and documentation your partners can build on.
Connect payment gateways, accounting platforms, CRMs, e-commerce, logistics and messaging services.
Two-way sync between systems with conflict handling, so records stay consistent without manual reconciliation.
Event-driven processes that react the moment something happens — an order placed, a payment received, a status changed.
Bridge older systems with no modern API through database integrations, file exchange or middleware.
Logging, retries and alerts so failed transfers are caught and resolved before anyone notices.
Our engineers start by spending time with the people who'll use what we build. You see your first improvement working early, and it gets better every week after. Once it's live, the same people stay to support it — or hand it over cleanly.
Day-to-day work was spread across Excel files and chat groups, making it hard to see what was happening or who was responsible. We built one system around the way the firm actually works, with key updates sent straight to WhatsApp.
From scattered Excel sheets and WhatsApp chaos to one clear system. Portabill's custom ERP — with WhatsApp insights — gave us real control over our operations.
Straight answers about how we work. If yours isn't here, ask us directly.
Any system with an API, and many without one. We regularly work with payment gateways, accounting platforms, CRMs, e-commerce platforms, messaging APIs and custom internal systems.
We design for failure: retries with back-off, dead-letter queues for problem records, alerts to the right people and dashboards showing sync health.
Yes. We design versioned, documented APIs with authentication and rate limiting, plus sandbox environments and developer documentation for your partners.
Absolutely. We often build integrations alongside internal teams, following your standards, repositories and review process.
