How this differs from a credit report
They get bought for each other and answer different questions. If yours is the first one below, buy the credit report — it does that better than we do.
| The question | A traditional credit report | A MiMi dossier |
|---|---|---|
| Will they pay my invoice in 30 days? | Yes | No |
| Payment behaviour & trade references | Yes | No |
| A credit score and recommended limit | Yes | No |
| Registered identity & address | Yes | Yes |
| Insolvency, liquidation, strike-off | Yes | Yes |
| Secured charges & liens, by lender | Sometimes | Yes |
| Litigation, each case linked to its docket | No | Yes |
| Debarment, exclusion, termination for default | No | Yes |
| Public-contract award history & who bought | No | Yes |
| Owner graph — what else the principals control | Sometimes | Yes |
| A written assessment framed to your decision | No | Yes |
| Every claim traceable to the filing behind it | No | Yes |
A credit report tells you whether to extend terms. A dossier tells you whether to enter the relationship at all — and what to verify first. We publish no score, because a rating is our judgement to defend and a filing is simply true.
