Hermes Buildathon · Track 03 · AI as Agency

Tallyzen

A financial services firm, run by agents.

Three agents that work like a real finance team — a Financial Advisor who talks to the owner, a Financial Analyst who researches the outside world, and an Accountant who reads the books in TallyPrime. They coordinate to do the work and to answer the hard questions. Built on Hermes.

What we're judged on

Three things a mentor told us to prioritize

This is the effective rubric. Every design choice below serves one of these — nothing else.

1

An end-to-end workflow

A complete job, from the owner's request all the way to a real outcome — not a menu of features.

2

Agents coordinating

Multiple agents visibly handing off and combining their work toward one outcome.

3

Tools in action

The partner tools we identified doing real work inside the flow, not bolted on.

The firm

Three agents, one team

The Advisor is the face and the orchestrator. It never answers alone — it spawns the Analyst (the outside world) and the Accountant (the books), then synthesizes.

The face + orchestrator

Financial Advisor

Talks to the owner, frames the question, delegates to the Analyst and Accountant, fuses their inputs into one recommendation, and delivers it.

Tools: Hermes · ElevenLabs · Wispr Flow
The outward eye

Financial Analyst

Researches the outside world — demand, prices, interest rates, regulatory conditions, competitors — and reports what it means for the decision.

Tool: Linkup (live web research)
The inward eye

Accountant

Speaks with TallyPrime. Pulls the current reality — sales history, cash, receivables, payables — and posts new entries. Keeps a check on the situation.

Tool: TallyPrime XML :9000
Flow 1 · the opener

Upload an invoice → it lands in Tally

The #1 ask across a year of waitlist (40% of signups). Proves the plumbing — and it's a coordinated chain, not one agent.

01Advisor

Receives the invoice photo/PDF on WhatsApp or Telegram, opens a job, delegates.

Wispr FlowHermes
02Extraction agent · vision

Reads the image → structured fields: vendor, GSTIN, date, line items, taxable value, CGST/SGST/IGST, total.

GPT-5.5 vision
03Validation & Enrichment agent

Checks the tax math and whether the vendor exists as a ledger. Unknown vendor or missing GSTIN → verifies it live via Linkup. Flags anything unresolved.

Linkup
04Booking agent

Maps to the correct ledgers, builds the voucher, posts to Tally on confirm, returns the voucher number.

TallyPrime :9000Convex audit trail
05Advisor

"Booked INV-2231 from Bajaj Steel — ₹1,50,000 (₹1,27,119 + ₹22,881 GST) as Purchase voucher V-104. Vendor GSTIN verified via Linkup."

Flow 2 · the showpiece

A seafood trader decides where to sell next

The Advisor can't answer this alone. It needs the books (Accountant) and the market (Analyst) at once — which is exactly what makes the coordination real.

The persona

Meenakshi Marine Exports · Thoothukudi, Tamil Nadu · prawn exporter

"With the US–Iran war, my US orders are drying up. Look at my last six months of prawn sales and tell me — should I shift to China, Vietnam and Southeast Asia?"
01Advisor

Frames the decision, states the plan, spawns two requests in parallel.

Wispr FlowHermes
02Accountant → Tally

Pulls 6 months of prawn sales by destination + customer: "₹4.2 Cr total — 62% to the US, and US is down 30% over the last two months. Top US buyer Gulf Coast Seafood owes ₹38 L, 55 days overdue. China 16%, Vietnam 12%."

TallyPrime :9000
03Analyst → Linkup

Researches the outside world: "China vannamei demand is strong; Vietnam is a re-processing hub for Indian raw material; the US carries anti-dumping duties on Indian shrimp and freight/insurance is spiking. Selling to China needs GACC + MPEDA registration (~weeks)."

Linkup
04Advisor synthesizes → voice

Fuses internal + external into one recommendation, spoken back to the owner.

ElevenLabsConvex
The outcome

"Your books already confirm the US is softening and ₹38 L is stuck there. The market backs the pivot: prioritize China — but start the GACC/MPEDA registration now, it's the long pole. Keep Vietnam as a re-processing channel, hold a small US allocation for paying buyers only, and collect that ₹38 L before extending more US credit. Loop your CHA in on the China paperwork."

Grounded, not hallucinated

Indian shrimp leaning on the US — and the live debate about diversifying to China and Southeast Asia — is a real industry story. Point Linkup at the real destination-market and regulatory data; let the "US–Iran war" be the narrative shock that starts the question. The Analyst returns facts a judge can verify.

Dodo Payments doesn't fit an advisory flow cleanly — include it only as an "activate your plan" checkout, or leave it out. A natural tool story beats a forced one.

Grounding & build discipline

Real demand behind it, one happy path to build

40%
of a year of waitlist asked for invoice → Tally. That's Flow 1.
80%
of signups are ₹50 Lakh ARR and up — established SMBs, India-first.
67%
said yes to a founder call — 20 high-intent businesses to validate with.
Build discipline

Bound the Analyst's research to 2–3 concrete Linkup queries. Rehearse one happy path per flow. Make every handoff visible — each agent posts its own line so the judge sees the coordination. Flow 2 (advisory) is the demo showpiece; note it reaches beyond the bookkeeping the waitlist asked for.
