The stack you already run, made to produce cleaner files.
Apsis Line takes a deliberate position: no new calculation engines, no shadow systems of record, no rip-and-replace. It is an intelligent middleware layer above the LOS — its job is to maximize what your existing LOS investment produces upstream of underwriting.
LOS-agnostic by architecture. The platform speaks MISMO 3.4 — the industry-standard interchange — and every vendor connection is an adapter seam, so Apsis Line can wire to any LOS. The integration is deepest today on ICE Encompass(application push, Partner Connect service orders, disclosure generation); running something else is an integration conversation, not a dead end — bring your LOS to the walkthrough.
The Integration Surface
| Layer | Connects to | What it does |
|---|---|---|
| LOS — system of record | Any MISMO 3.4-capable LOS · deepest today: Encompass (ICE Mortgage Technology) | MISMO 3.4 ULAD application push — the industry-standard interchange every major LOS accepts — with field-level write-back and receipts, disclosure generation and tracking. Your LOS remains the single source of record. |
| Vendor services | LOS-native service channels · e.g. Encompass Partner Connect (EPC) | One governed connection powers the service orders a file needs before disclosure: credit, flood determination, closing fees, address verification, and the automated compliance review. On Encompass these ride EPC; on other platforms, the same seams wire to that LOS’s service channels or direct vendor APIs. |
| Credit | Your credit provider — direct bureau APIs or your LOS’s credit channel (e.g. Encompass Partner Connect) | Soft pulls for the borrower journey (no score impact), hard pulls in the workspace — each behind per-person authorization, never without it. |
| Compliance review | Your compliance engine — e.g. via Encompass Partner Connect, or the review service you run today | Every file is reviewed before disclosures can launch; the platform holds the file unless the review affirmatively clears. Fail-closed. |
| Closing fees | Your fee service — e.g. via Encompass Partner Connect, or your current fee vendor | Real fee data on the file ahead of disclosure — the Loan Estimate reflects ordered fees, not placeholders. |
| Flood | Your flood-determination vendor — e.g. via Encompass Partner Connect | Ordered and attached before disclosure; a required member of the services gate. |
| Product & pricing | Pricing engine connectivity | Product and pricing quotes (par and rate-stack options) once your pricing engine is connected; the borrower’s chosen product — rate, points, term — carries through the math and onto the LOS file exactly as selected. |
| AUS | Fannie Mae DU · Freddie Mac LPA | Dual-AUS submission architecture with normalized findings, so underwriting posture is visible upstream. |
| Home valuation | Your AVM provider — e.g. RentCast | Per-property value estimates in the borrower journey — licensed for consumer display, clearly labeled as an estimate, never a substitute for the appraisal. |
| E-signature & delivery | LOS-native disclosure delivery | Generated packages delivered for borrower e-signature with send dates recorded to disclosure tracking. |
| CRM | Consumer-direct and retail CRM connectors | Inbound lead prefill and outbound milestone status for the CRM your teams already run. |
| Lead partners | Adapter-based intake | Signed-token redirects and webhook lead models normalize into one attribution spine; adding a partner is configuration, not code. |
Vendor and product names describe technical interoperability only and do not imply endorsement, sponsorship, or partnership. Specific vendor availability is confirmed per deployment against your licensing.
Integration honesty, as an architecture
Every vendor connection in the platform is a governed seam: credentials live server-side only, the platform decides simulated-versus-live on the server, and every result is labeled with its source. In a sandbox the platform demonstrates the full flow honestly; in production the same seams run live — the experience, the math, and the gates are identical either way. Your integration test tells you the truth.
Service orders carry durable transaction references, so a billable service is never accidentally double-ordered, and every order is reconcilable against the vendor invoice. More on the credential and data posture →
