Roadmaps and public changelogs for product teamsChennai · since 2023

A roadmap worth
publishing.

Cartographer holds the next four quarters of a product and sets them like a printed schedule — owners, confidence, and the date each thing actually shipped. One page your team edits and anyone can read.

Every entry keeps its own history. When work ships, the entry is struck through, the changelog gets a dated note, and the people who asked for it hear about it that morning.

Payanam publishes this page every Tuesday

payanam.in/roadmap — 14 initiatives, four quarters, read 41,200 times last month

Payanam builds fleet-operations software in Coimbatore for transport companies running 20 to 400 lorries. This is their roadmap as their customers see it, with nothing removed — the same page their four product people edit, published to their own domain. Confidence is what the owner will stand behind, not what sales would like to promise.

Nine ways of asking the same thing become one entry. Everyone behind it stays attached and keeps being told what happens next.

“Can we see what a trip costs before we quote it?”
“Diesel and toll should be on the quote screen, not the trip sheet.”

The entry takes a quarter, an owner and a confidence, and goes onto the page customers read. Confidence is edited in public — it moved twice.

Our sales team used to promise things off a slide. Now they send the roadmap link and let a customer read the confidence for themselves. We have lost one deal over it and saved a dozen renewals.

Trip cost forecasting

Quote a load knowing what it costs to run, and see the variance when the trip closes.

Before you quote a trip, Payanam estimates what it will cost to run: diesel at the rate you last paid, tolls from the route’s FASTag history, driver allowance from the roster, and a share of maintenance based on the vehicle’s last twelve months.

Quote against the forecast and the variance lands on the trip sheet when the trip closes. On the 214 trips run against a forecast during the beta, the estimate came within ₹900 of the real cost four times out of five.

Asked for by 152 accounts, first raised by Bharathi Transports in Tiruppur in November 2025. Everyone who asked had this note in their inbox before the office opened.
