In my own shop (garage 😄 ), I'd finish a job, look at the invoice, and still not really know if I actually made money on it once you factor in ink, the substrate, machine time, and my own hours. Spreadsheets helped but were a pain to keep up. For context, I'm using Eufymake E1.

I looked at the paid options out there and they were either overkill for a small shop or more than I wanted to pay every month just to price my own jobs — so I built what my studio actually needed, and I've decided to give it away free to the community.

Meet InkTracker. What it does:

• 🧮 Costs out a job properly — ink per channel (C/M/Y/K/W/Gloss/Flex White), materials, machine depreciation, labor, and overhead — then suggests a price and shows your margin (🟢 Strong / 🟡 Target / 🔴 Loss)
• 🩸 Tracks ink — what each color actually costs you and how much is left in each cartridge
• 📦 Inventory — materials and cartridge stock so you're not caught short mid-run
• 📈 Analytics — revenue, profit, and monthly ink usage so you can spot trends and plan reorders
• 🛠️ Service log — head cleans, cartridge swaps, maintenance history
• 🖨️ Printable job worksheets for the shop floor, plus CSV/PDF export

It runs on your own computer — free, no subscription, no account, your numbers stay yours — and you can even install it like an app on your phone or tablet.

I'd love to hear what features would help your shop, or if anything's unclear. Happy to help anyone get it running. 🙌

I've been working on this for a while and finally decided to open-source it as my contribution to the community.

InkTracker answers the question I kept asking after every job: is this actually profitable?

It calculates true cost per job — ink (per channel: C/M/Y/K/W/Gloss/Flex White), materials, machine depreciation, labor, and overhead — then gives you a recommended price and a live margin badge (Strong / Target / Minimum / Loss). Also, supports mobile (Android or IOS).

Features:

• 🧮 Job-costing wizard with full COGS breakdown
• 🩸 Ink & cartridge tracking (cost + remaining per color)
• 📦 Inventory for materials and cartridge stock
• 📈 Analytics — revenue, profit, monthly ink-usage trends
• 🛠️ Service/maintenance log
• 🖨️ Printable worksheets, CSV/PDF export, installable PWA (works offline)

Why self-hosted: it's GPL-3.0, runs in Docker, and your data never leaves your machine — no accounts, no subscription, no tracking.

I built it for my own studio and it changed how I price work. Would love feedback, feature requests, or bug reports — and a ⭐ helps if you find it useful. Happy to answer anything in the comments.
