_Cost per business unit_

## Cost per order, per user, per request.

Tell ZopNight what your business counts (monthly users, orders, API calls, sign-ups) and the cost report gains a second line: infrastructure spend per unit. The number your CFO actually asks about.

- 3 — ways to send your numbers
- 5 — ready-made metrics
- Daily — pull from your own endpoint
- Per team — or per tag, not just org-wide

Free to start. No card. The playground just needs your work email.

## Your metric, our cost, one line.

The denominator lives in your systems. The numerator lives in ours.

- 01. Define the unit — Pick from five common metrics (monthly and daily active users, requests, transactions and sign-ups) or name your own.
- 02. Send the numbers — Push them from your pipeline by API, upload a CSV for a backfill, or register an endpoint and ZopNight pulls it daily. All three land in the same place.
- 03. Read cost per unit — The cost trend gains a second axis: spend divided by your metric, daily, weekly or monthly. Periods with no metric value are skipped, not counted as zero.
- 04. Slice it — Scope it to a team or a tag and the cost side follows. Send per-team values too and the unit side follows.

## Your numbers stay yours.

Built for the metric you would not put in a cloud account.

- The metric: Business counts live in your systems, not your cloud, so you supply them. ZopNight supplies the cost.
- Ingest: Push API, a CSV upload of up to 5,000 rows, or a daily pull from an HTTPS endpoint you register. A test fetch runs the full pull before the schedule starts.
- Credentials: Pull credentials are encrypted with AES-256-GCM in the same vault as cloud credentials. Every pull passes a network guard that refuses private and internal addresses.
- Honest maths: Cost per unit is total cost over total units for each period. A period with no units is skipped rather than drawn as a spike.

## Give the board a number it can use.

Connect an account, add one business metric, and cost per unit appears on the next report.
