What the awards don't tell you about CSSI, LLC
23 awards tell you CSSI, LLC has won work. They do not tell you whether the company is solvent, who controls it, whether a lender holds a charge over its assets, or whether it has been sued by the people it delivered to. The report checks each of those and names every source it checked, including the ones that came back clean — for CSSI, LLC that means corporate affiliates, competitors in architecture & engineering and financial footprint, itemized with the filing behind each fact.

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.
