# Best LOS with FIS Core Integration > An independent, ranked guide to the best loan origination systems that integrate with FIS cores (Horizon, IBS, Modern Banking Platform) for banks in 2026. Source: https://thelosdirectory.com/best/los-fis-integration --- 2026 Guide By The LOS Directory Editorial Team · Published June 8, 2026 · Last verified August 9, 2026 · Next review November 9, 2026 For a bank on an FIS core, FIS Commercial Loan Origination is the most native fit, integrating Horizon, IBS, and the Modern Banking Platform inside the FIS ecosystem. Best-of-breed alternatives that integrate with FIS include Fuse for AI-native origination on flat-fee pricing, Baker Hill for value, nCino for multi-product breadth, Encompass for mortgage volume, and Abrigo for credit-led commercial. The FIS skew is enterprise, so community banks usually weigh a best-of-breed platform that connects to FIS against the native FIS suite. An FIS core has a different gravity than Fiserv or Jack Henry: FIS runs several enterprise cores (Horizon, IBS, and the Modern Banking Platform), and its installed base leans toward larger banks. So the loan origination system (LOS) question on an FIS core often starts with whether the native FIS Commercial Loan Origination suite fits, then asks which best-of-breed platforms connect cleanly enough to justify leaving the FIS stack. No single LOS wins every FIS shop. FIS Commercial is the native enterprise option; nCino and Abrigo integrate with FIS but bring breadth or credit-risk depth; Encompass owns mortgage. We ranked these for institutions standardized on FIS, weighting how native the integration is to your specific core line, the lending breadth covered, and the fit for the larger banks FIS tends to serve. For the connection mechanics across all three cores, see /guides/core-banking-integration-guide.

It looks at the depth and proof of the FIS integration path across Horizon, IBS, and the Modern Banking Platform including native versus third-party connection, the lending breadth that integration covers, the credit and compliance work the platform removes, and fit for the mid-to-large banks FIS typically serves against cost. Drawn from vendor documentation, published customer results, third-party reviews on G2 and Capterra, and our own evaluation. Scores are our editorial read on a 5-point scale. The Overall score tracks each platform’s placement in this guide; Features, Ease, and Value are scored independently and do not always follow that order. ## Quick Comparison | # | Platform | Overall | Features | Ease | Value | Best For | | --- | --- | --- | --- | --- | --- | --- | | #1 | [FIS Commercial Loan Origination](https://thelosdirectory.com/platforms/fis-commercial) Best Native Integration | 4.3 | 4.4 | 3.6 | 3.7 | Mid-to-large banks ($5B+) already in the FIS ecosystem that want the deepest native core connection | | #2 | [Fuse](https://thelosdirectory.com/platforms/fuse) Best AI-Native Option on an FIS Core | 4.2 | — | — | — | Credit unions and community banks on FIS wanting AI automation | | #3 | [Baker Hill UN/FY (formerly NextGen)](https://thelosdirectory.com/platforms/baker-hill) Best Value Multi-Product | 4.1 | 4.2 | 4.1 | 4.5 | FIS banks wanting commercial, consumer, and SBA in one platform without enterprise pricing | | #4 | [nCino](https://thelosdirectory.com/platforms/ncino) Best for Multi-Product Breadth | 4.0 | 4.7 | 3.6 | 3.6 | FIS banks that want commercial, consumer, and mortgage in one CRM-backed platform | | #5 | [Encompass](https://thelosdirectory.com/platforms/encompass) Best for Mortgage Volume | 3.9 | 4.5 | 3.5 | 3.4 | FIS banks running real residential mortgage volume | | #6 | [Abrigo](https://thelosdirectory.com/platforms/abrigo) Best for Credit-Led Commercial | 3.8 | 4.4 | 4.0 | 4.3 | FIS banks, especially under $10B, underwriting commercial inside a credit-risk platform | #1 ![FIS Commercial Loan Origination logo](https://thelosdirectory.com/logos/fis-commercial.png) ## [FIS Commercial Loan Origination](https://thelosdirectory.com/platforms/fis-commercial) Best Native Integration 4.3/5 Our score Features4.4 Ease3.6 Value3.7 FIS Commercial Loan Origination is the native commercial LOS inside the FIS Commercial Lending Suite, integrating Horizon, IBS, and the Modern Banking Platform. It is highly configurable for complex commercial, CRE, and equipment lending, with a digital borrower experience, risk analysis, and relationship-profitability tools. For a bank already on an FIS core, it is the connection that needs no third-party bridge. Standout: Integrates FIS Horizon, IBS, and the Modern Banking Platform inside the FIS Commercial Lending Suite, with risk analysis and relationship profitability built in. FIS Commercial leads on native integration, which is what this page is about. Nothing connects to Horizon, IBS, or the Modern Banking Platform as directly as FIS's own suite, and its configurability suits the complex commercial shops FIS tends to serve. The trade-offs are scope and cost: enterprise pricing makes it impractical for community banks, the value is concentrated inside the FIS ecosystem, and innovation can lag purpose-built commercial vendors. For a mid-to-large FIS bank, the native fit and configurability are the draw. #### Key Strengths - ✓ Highly configurable for complex commercial lending requirements - ✓ Digital borrower experience for commercial loan applications - ✓ Risk analysis and profitability tools built into the platform #### Key Limitations - ✗ Enterprise pricing makes it impractical for community banks - ✗ Best value within FIS ecosystem, limited appeal outside it - ✗ Innovation pace can lag behind purpose-built commercial LOS vendors Best for: Mid-to-large banks ($5B+) already in the FIS ecosystem that want the deepest native core connection Pricing: Enterprise licensing; typically bundled with broader FIS banking relationship Deployment: cloud [Full review](https://thelosdirectory.com/platforms/fis-commercial) [Alternatives](https://thelosdirectory.com/alternatives/fis-commercial) #2 ![Fuse logo](https://thelosdirectory.com/logos/fuse.png) ## [Fuse](https://thelosdirectory.com/platforms/fuse) Best AI-Native Option on an FIS Core 4.2/5 Our score An AI-native origination and account opening platform built on large language models, listing FIS among its core integrations and aimed at credit unions and community banks replacing legacy origination. Standout: Flat annual pricing with no per-loan transaction fees, and 71% reported automation within a year. FIS skews enterprise, and Fuse is the opposite end of that range: a smaller institution on an FIS core that wants AI-driven document review, fraud detection, and decisioning without enterprise pricing or an enterprise timeline. Flat $50K-$100K annual pricing helps the math. Weigh the Series A risk, the absence of full residential mortgage, and the thin independent review record, and confirm the integration on your specific FIS line. #### Key Strengths - ✓ AI-native architecture delivers measurable automation — 71% average within one year - ✓ Flat annual pricing ($50K–$100K) with no per-loan transaction fees - ✓ $5M rescue fund subsidizes switching costs for credit unions on legacy contracts #### Key Limitations - ✗ Series A startup (founded 2020) competing against deeply entrenched, publicly traded incumbents - ✗ No mortgage origination — supports HELOC but not full residential mortgage with TRID/RESPA compliance - ✗ No G2, Capterra, or third-party review presence yet — limited independent validation Best for: Credit unions and community banks on FIS wanting AI automation Pricing: Flat annual subscription with performance guarantees Deployment: cloud [Full review](https://thelosdirectory.com/platforms/fuse) [Alternatives](https://thelosdirectory.com/alternatives/fuse) #3 ![Baker Hill UN/FY (formerly NextGen) logo](https://thelosdirectory.com/logos/baker-hill.png) ## [Baker Hill UN/FY (formerly NextGen)](https://thelosdirectory.com/platforms/baker-hill) Best Value Multi-Product 4.1/5 Our score Features4.2 Ease4.1 Value4.5 A unified origination platform covering commercial, consumer, small business, and SBA, with FIS, Fiserv, and Jack Henry listed as core integrations. Baker Hill NextGen gives an FIS bank multi-product lending and analytics in one cloud system without the Salesforce layer nCino carries or the enterprise pricing the native FIS suite commands, keeping officers in one platform across products. Standout: Names FIS among its three core integrations and reports 45% fewer input errors after rollout, without a Salesforce dependency. Baker Hill is the value option for FIS banks in the $500M to $10B range that find FIS Commercial too enterprise and nCino too Salesforce-heavy. It integrates with FIS rather than running native, so you add a connection, but you gain SBA-strong, multi-product workflows at a lower total cost. It carries no mortgage module and full deployments run 6 to 9 months. For a smaller FIS bank that wants breadth without the enterprise bill, it is the practical middle. #### Key Strengths - ✓ True multi-product platform without Salesforce dependency - ✓ Baker Hill says more than 20,000 bankers use its loan origination products (as of September 2026) - ✓ Baker Hill says UN/FY can reduce origination costs by up to 60 percent #### Key Limitations - ✗ No mortgage origination, need a separate system for mortgage - ✗ Smaller vendor, less name recognition than nCino or Encompass - ✗ Implementation timeline can extend to 6-9 months for full deployment Best for: FIS banks wanting commercial, consumer, and SBA in one platform without enterprise pricing Pricing: SaaS subscription based on asset size and module selection Deployment: cloud [Full review](https://thelosdirectory.com/platforms/baker-hill) [Alternatives](https://thelosdirectory.com/alternatives/baker-hill) #4 ![nCino logo](https://thelosdirectory.com/logos/ncino.png) ## [nCino](https://thelosdirectory.com/platforms/ncino) Best for Multi-Product Breadth 4.0/5 Our score Features4.7 Ease3.6 Value3.6 The broadest cloud lending platform, built on Salesforce, with FIS among its named core integrations alongside Fiserv, Jack Henry, Temenos, and Finastra. nCino unifies commercial, consumer, and mortgage origination with spreads, credit memos, and a real CRM, then boards to the core. For an FIS bank that wants best-of-breed breadth across products rather than commercial-only, nCino is the step beyond the native FIS suite. Standout: Names FIS among five core integrations and reports commercial loans originate 54% faster once boarding runs through one system. nCino integrates with FIS rather than being native to it, so you take on a connection the FIS suite gives you directly. What you buy is reach: commercial, consumer, and mortgage in one platform with a Salesforce CRM, where FIS Commercial is commercial-focused. The cost is the Salesforce license stack and 6-to-12-month deployments. Confirm the integration on your FIS line, whether Horizon, IBS, or the Modern Banking Platform, rather than assuming the generic logo covers all three. #### Key Strengths - ✓ True multi-product platform, one system for all loan types - ✓ Salesforce ecosystem benefits (AppExchange, reporting, AI) - ✓ Strong commercial lending workflows with automated spreading #### Key Limitations - ✗ Salesforce dependency, adds licensing complexity and cost - ✗ Implementation can be lengthy (6-12 months for full deployment) - ✗ Borrower-facing portal feels secondary to the bank-staff interface Best for: FIS banks that want commercial, consumer, and mortgage in one CRM-backed platform Pricing: Subscription (per-user, tiered by modules) Deployment: cloud G2: 4.2/5 (14 reviews) [Full review](https://thelosdirectory.com/platforms/ncino) [Alternatives](https://thelosdirectory.com/alternatives/ncino) #5 ![Encompass logo](https://thelosdirectory.com/logos/encompass.svg) ## [Encompass](https://thelosdirectory.com/platforms/encompass) Best for Mortgage Volume 3.9/5 Our score Features4.5 Ease3.5 Value3.4 The dominant U.S. mortgage LOS, owned by ICE, with FIS among its named core integrations alongside Black Knight and Optimal Blue. Encompass handles end-to-end residential origination with the deepest compliance automation in the category and a 300-plus partner network. For an FIS bank whose mortgage book is large enough to need a dedicated engine, it is the mortgage-side connection, since the native FIS suite is commercial. Standout: Roughly half of U.S. mortgage lenders run Encompass, and FIS sits inside its 300-plus integrated partner ecosystem. Encompass is mortgage only, so on an FIS core it solves one product, not the lending stack. Where it fits it fits deeply: industry-standard, easiest to staff, strongest compliance. The cost is the highest in the category, implementations run 6 to 12 months, and the SDK transition with a December 2026 deadline adds uncertainty. An FIS mortgage shop should treat it as the default for that book and pair it with FIS Commercial or Abrigo for commercial lending. #### Key Strengths - ✓ Industry-standard platform — easiest to find trained staff - ✓ Deepest compliance automation in the market - ✓ Massive partner ecosystem reduces integration headaches #### Key Limitations - ✗ Expensive — total cost of ownership is the highest in the category - ✗ Complex implementation (6-12 months typical) - ✗ Can feel bloated for smaller shops that don't need every feature Best for: FIS banks running real residential mortgage volume Pricing: Subscription (per-seat + per-loan transaction fees) Deployment: cloud, hybrid G2: 4.2/5 (61 reviews) [Full review](https://thelosdirectory.com/platforms/encompass) [Alternatives](https://thelosdirectory.com/alternatives/encompass) #6 ![Abrigo logo](https://thelosdirectory.com/logos/abrigo.png) ## [Abrigo](https://thelosdirectory.com/platforms/abrigo) Best for Credit-Led Commercial 3.8/5 Our score Features4.4 Ease4.0 Value4.3 The credit-and-risk platform with Sageworks roots, listing FIS among its core integrations alongside Fiserv and Jack Henry. Abrigo runs commercial and SBA origination inside the same system a bank uses for spreading, risk rating, CECL, and BSA/AML. On an FIS core, the credit decision and the boarded loan share a data set rather than living in separate tools. Standout: Names FIS among its core integrations and ties the commercial decision to risk rating, CECL, and BSA/AML on one data set. Abrigo fits FIS banks where credit risk and examiner scrutiny lead the commercial decision, particularly community and lower-mid-size institutions that find the native FIS suite oversized. Connecting origination to CECL and portfolio monitoring is something FIS Commercial and the pure origination engines do not do, and Abrigo's 2,400-plus base sits in this segment. It is commercial and SBA only, with no mortgage, and the interface trails newer cloud tools. For credit-led FIS shops, the integration is the point. #### Key Strengths - ✓ Unmatched integration between origination and credit risk analytics - ✓ Purpose-built for community bank commercial lending workflows - ✓ Strong regulatory and compliance toolkit (CECL, CRE concentration, BSA) #### Key Limitations - ✗ No mortgage origination module, commercial/small business only - ✗ User interface lags behind newer cloud-native competitors - ✗ Integration between legacy product lines (Sageworks, Banker's Toolbox) still evolving Best for: FIS banks, especially under $10B, underwriting commercial inside a credit-risk platform Pricing: Subscription (modular, LOS, credit risk, compliance sold separately or bundled) Deployment: cloud G2: 4.6/5 (74 reviews) [Full review](https://thelosdirectory.com/platforms/abrigo) [Alternatives](https://thelosdirectory.com/alternatives/abrigo) ## Native FIS suite or best-of-breed on an FIS core? FIS sells its own commercial LOS inside the FIS Commercial Lending Suite, integrating Horizon, IBS, and the Modern Banking Platform. For a larger bank already in the FIS ecosystem, that native connection and the suite's configurability are a strong default. The question is whether commercial-only coverage and enterprise pricing fit, because the moment you need consumer, mortgage, or deeper credit-risk integration, you are weighing a best-of-breed LOS that connects to FIS against the native suite. Because FIS skews toward larger banks, the calculus differs from Fiserv and Jack Henry. A community bank on an FIS core often finds the native suite oversized and lands on Abrigo or Baker Hill for credit-led or value-focused commercial lending; a multi-product bank reaches for nCino. The connection mechanics behind any of these paths, certification, maintenance, and what breaks when each side updates, are covered once in /guides/core-banking-integration-guide rather than repeated here. ## How to validate an FIS integration in a demo FIS is several enterprise cores, and a stated integration may have been certified on a line you do not run. Push past the logo before you sign. - Name your FIS core line and confirm a production integration on it: Horizon, IBS, or the Modern Banking Platform, not just "FIS." - Make the vendor demonstrate loan boarding and GL posting to the core on test data, and confirm the LOS sees existing core relationships at application. - If you are a community bank, pressure-test whether the native FIS suite is more platform than you need before defaulting to it on integration alone. - Get the maintenance story: enterprise cores update on their own cadence, so ask who keeps the connection certified and what it costs annually. - Separate the products. The FIS suite is commercial; mortgage and consumer needs point to Encompass or a best-of-breed multi-product platform. ## How to Choose an LOS for an FIS Core ### 1. Weigh the native FIS suite against best-of-breed FIS Commercial Loan Origination integrates Horizon, IBS, and the Modern Banking Platform natively and suits complex, larger commercial shops. A best-of-breed LOS like nCino or Abrigo connects to FIS but adds breadth or credit-risk depth the native suite does not. Decide whether a native commercial connection or wider capability matters more before shortlisting. ### 2. Match the integration to your FIS core line FIS runs Horizon, IBS, and the Modern Banking Platform. Confirm the LOS has a production integration on the specific line your bank uses, and ask for a reference customer on it. A generic "integrates with FIS" claim may have been certified on a core you do not run. ### 3. Size the platform to your institution FIS leans enterprise, and so does its native suite, which makes it impractical for community banks on cost. If you are under $10B on an FIS core, Abrigo and Baker Hill are usually the better-sized commercial options. Match the platform to your asset size, not just the core logo. ### 4. Buy for your lending mix The connection only matters for what you originate. FIS Commercial and Abrigo cover commercial; Baker Hill adds consumer and SBA; nCino adds mortgage; Encompass owns mortgage; Numerated digitizes business-banking intake. Pick the platform whose breadth fits your book, then verify the FIS path for those products. ### 5. Price the connection and its upkeep On an FIS core, integration is a project and a recurring cost. Get implementation timelines (nCino and Encompass run 6 to 12 months), price the Salesforce layer under nCino separately, and ask who maintains the certified connection as both FIS and the LOS update. The native FIS suite avoids the third-party connection but commands enterprise pricing. ## Frequently Asked Questions What is the best LOS with FIS core integration? For the deepest native connection, FIS Commercial Loan Origination integrates Horizon, IBS, and the Modern Banking Platform inside the FIS ecosystem and suits larger commercial banks. Best-of-breed alternatives that integrate with FIS include Fuse for AI-native origination on flat-fee pricing, Baker Hill for value, nCino for multi-product breadth, Encompass for mortgage, and Abrigo for credit-led commercial. Confirm the vendor has a production integration on your specific FIS core line. Which FIS core lines do these LOS platforms integrate with? FIS runs several enterprise cores, including Horizon, IBS, and the Modern Banking Platform. The native FIS Commercial suite integrates all three. Third parties like nCino, Abrigo, Baker Hill, Encompass, and Numerated list "FIS" generically rather than naming the line, so confirm the vendor has a production integration on your specific FIS core and a reference customer on it. Should a community bank on FIS use the native FIS suite? Often not. FIS Commercial Loan Origination is enterprise-priced and configured for the larger, complex commercial shops FIS tends to serve, which makes it impractical for many community banks. If you are under $10B on an FIS core, Abrigo for credit-led commercial or Baker Hill for value-focused multi-product lending usually fits better, both integrate with FIS, and you avoid paying for enterprise scale you will not use. I run mortgage on an FIS core. Which LOS fits? The native FIS commercial suite does not cover mortgage, so for real residential volume you want a dedicated engine. Encompass is the dominant U.S. mortgage LOS and lists FIS among its core integrations. It is mortgage only and the most expensive option in the category, so FIS banks that also originate commercial typically pair it with FIS Commercial or a platform like Abrigo rather than expecting one system to cover both. How long does an FIS LOS integration take to stand up? It depends on the platform. Full deployments of nCino or Encompass commonly run 6 to 12 months, with the core integration one workstream inside that, and the native FIS suite carries the implementation complexity typical of enterprise platforms. Digital layers like Numerated deploy faster. Ask each vendor for a timeline that includes the certified FIS connection on your specific core line, not just software configuration. Is core integration the same across FIS, Fiserv, and Jack Henry? The mechanics rhyme but each core, and each line within it, certifies integrations separately, so strength on one does not transfer. FIS is distinctive in skewing toward larger banks and offering a native commercial suite as the default. We cover the shared connection mechanics in /guides/core-banking-integration-guide and rank the Fiserv and Jack Henry options on their own pages. Verify the integration against the exact core you run. Researched and maintained by The LOS Directory Editorial Team.
