ParchiPay: Channeling Your Inner Sloth with Gemma & LangGraph to Turn Messy Scribbled "Parchis" into Instant Paid Invoices

Description and use

ParchiPay leverages Gemma and LangGraph to automate contractor quoting, cutting time from 45 minutes to 15 seconds and preventing revenue leakage.

Problem

Independent trade contractors lose hours to manual estimating and quoting, deciphering messy handwritten slips (“parchis”) and voice notes, checking inventory, calculating GST, and often forgetting billable labor, leading to severe revenue leakage.

Outcome

ParchiPay reduces quoting time from up to 45 minutes to about 15 seconds, eliminates math hallucinations by separating cognition and arithmetic, and prevents revenue leakage by auditing missing labor and auto‑generating purchase orders.

Workflow

• Snap & Speak: capture photo of parchi and/or record voice note
• Multimodal Cognition with Gemma: parse handwriting, reconcile audio, map to catalog SKUs
• Deterministic Inventory & GST Engine: check 3‑tier stock, compute line‑item GST
• Cognitive Revenue Guard: audit quoted materials, suggest missing labor/add‑ons
• Autonomous Supplier Purchase Orders: draft restock orders for out‑of‑stock items
• Human‑in‑the‑Loop Approval & Dispatch: contractor reviews dashboard, toggles suggestions, approves, system generates invoice link, sends Brevo email and WhatsApp wa.me link

Evidence

Every day, contractors lose hours to the single most dreaded, brain‑draining task in their business: manual estimating and quoting.

The contractor glances at the dashboard, toggles the suggestions with one tap, and approves. ParchiPay immediately generates a customer portal link, sends a Brevo transactional email, and prepares a WhatsApp wa.me instant invoice link.
