Part 1

What SIN 522310 covers

522310 Services include assisting agencies on cross-cutting issues, asset marketability, equity monitoring, originations, and addressing any other considerations regarding the acquisition, management and/or resolution of an asset; assisting agencies in servicing, monitoring and maintaining loan assets such as establishing loan database, remittance processing, processing loan cancellations and consolidations, billing services, and servicing troubled loans which may include borrower negotiations, restructuring, foreclosure and supervision of the sale of the collateral and workout agreements.

The official record maps this SIN to NAICS 522310 and PSC R704. Those codes are not the whole strategy, but they help explain how the offering is categorized for buyers and reviewers.

Part 2

How to prepare the offer story

For service-oriented SINs, keep the service description, labor categories, pricing support, and past-performance examples aligned. A reviewer should be able to see what work is being sold, who performs it, and why the rate story is defensible.

If the SIN is being added through eMod, write down what changes operationally: new scope, new pricing, new files, catalog impact, and who owns maintenance after approval.

Part 3

Buyer and SEO language to keep straight

Use the SIN number, title, category, and subcategory together: SIN 522310 - Financial Advising, Loan Servicing and Asset Management Services - Professional Services - Financial Services. That combination helps a buyer understand the lane quickly and helps the page avoid becoming a vague keyword page.

When writing capability language, explain the actual deliverables and evidence. Do not make the SIN carry the whole message by itself.

Examples

What this looks like in practice

Real-world checkHow to test SIN 522310 before building files

Start with the official title and description: Financial Advising, Loan Servicing and Asset Management Services sits under Professional Services > Financial Services. Then compare your actual commercial offering to that scope, not only to the NAICS code.

If the fit still looks strong, build the proof stack: offering description, pricing support, past performance or product support, and any SIN-specific files the current GSA instructions require.

  • Confirm scope language.
  • Check NAICS and PSC signals.
  • Match the pricing file to the offering type.
  • Keep the support package reviewer-friendly.

Frequently asked questions

Is SIN 522310 part of TDR?

The Refresh 32 workbook marks TDR as Y for this SIN. GSA states that TDR became mandatory across MAS SINs with Refresh 31, so contractors should still verify current contract reporting instructions in official GSA sources.

Can order-level materials be used with SIN 522310?

The workbook marks OLM as Y. OLM treatment should always be verified against the current MAS solicitation, mass modifications, and contract-specific instructions.

Should I pick a SIN only because the NAICS matches?

No. NAICS helps, but SIN selection should be based on the actual offering, official SIN description, category/subcategory, pricing files, and buyer acquisition path.
