Spendassay vs. Amberflo
Amberflo meters what you sell. Spendassay audits what you spend.
Amberflo is metering and billing infrastructure for companies that sell AI products. It tracks usage events precisely and turns them into accurate usage-based invoices. That is real engineering, and teams that monetize AI usage rely on it. Spendassay does a different job. It sits on the buyer side and audits every dollar you spend on AI across vendors, tying that spend to what your engineers ship. One is built to help you bill your customers; the other is built to tell your CFO what your AI spend bought.
The one-line difference
Amberflo meters and bills the AI usage you sell; Spendassay audits the AI spend you buy against shipped output.

Side by side
Built for different questions
| Dimension | Amberflo | Spendassay |
|---|---|---|
| Primary job | Meter usage and bill your customers for the AI you sell | Audit the AI you buy and tie it to shipped output |
| What it measures | Usage events and metered cost for invoicing and usage-based billing | Spend across every AI vendor mapped to team-level output |
| Connects spend to shipped output | Not the goal; it prices and bills usage | Yes; every dollar links to what teams shipped, team-level, never individual rankings |
| Independence | Instruments the products you build and sell | Independent cross-vendor auditor; scores no vendor and no engineer |
| Evidence on every number | Metered event counts feeding billing | Each dollar carries a proof level (Counted, Compared, Estimated) and shows its formula |
| How you buy | Self-serve signup and a free trial; pricing on their site, enterprise is contact-sales | Free self-serve Snapshot; Observe $16/eng-mo, Control $40/eng-mo, all published |
| Pricing | Public and usage-based, with a free-forever tier (the first 10,000 meter events a month), then per-unit pricing. Enterprise is quoted. | Published and self-serve: a free Snapshot, then $16 per covered engineer per month (Observe) and $40 (Control). Priced per engineer, never as a percentage of your AI spend. |

Common questions
Spendassay and Amberflo
- Is Amberflo a competitor to Spendassay?
- Not really. Amberflo is metering and billing infrastructure for companies that sell AI products, so it runs on the revenue side. Spendassay is a buyer-side auditor of the AI you purchase. Different altitude, different buyer, and many teams have reason to run both.
- Can I use both?
- Yes. If you sell an AI product, Amberflo meters usage and bills your customers. Spendassay separately audits what you spend on AI vendors and ties it to shipped output for your CFO. They touch different sides of the ledger and do not overlap.
- Does Spendassay do what Amberflo does?
- No. Spendassay does not meter usage events or generate invoices, and the audit never writes to your systems. It reads spend metadata across vendors, attaches a proof level and formula to each dollar, and produces a neutral AI cost report. If you need to bill customers for usage, that is Amberflo's job, not ours.
