## The challenge

Fit-out and construction quoting typically moves through disconnected stages, from drawing takeoff to procurement to final quotation, with language barriers adding friction across teams.

## What we built

A 5-stage connected workflow platform taking a project from drawing through to quotation, supporting both English and Chinese-speaking teams throughout. It was built as a SaaS product: Stripe handles payments, OpenRouter orchestrates requests across AI models, and Langfuse traces every model call so quality and cost can be monitored.

## The result

The workflow now runs as a single connected system rather than five disconnected handoffs, in both languages.

## Built with. The SaaS and AI infrastructure behind the platform.

### Stripe

Payment integration for the SaaS product.

### OpenRouter

Model orchestration: one interface for routing requests across AI models.

### Langfuse

LLM observability: tracing model calls to monitor quality and cost.

## What the client says.

AI SaaS for construction

> “We needed a platform that could handle complex construction workflows without breaking down every week. Avinya Labs delivered exactly that. What stood out even more was their commitment after launch: when a critical issue came up, the team stayed up until midnight to make sure we weren't left hanging.”
