SKL Invoicing + AI Tax Agent

Invoicing for builders, with an AI tax agent that actually knows HMRC's rules.

A PHP invoicing tool for a construction company, with a built-in AI Tax Agent that helps users make sense of their tax position.

Rather than letting the model improvise, the agent answers with retrieval-augmented generation over a knowledge base scraped from HMRC's VAT and CIS (Construction Industry Scheme) guidance — so responses are grounded in real source material, not guesswork.
