Cross-selling is how financial institutions grow revenue from existing customers. A checking account holder who receives a deep link to a pre-approved savings account offer is far more likely to convert than one who sees a generic banner ad. The deep link removes friction: one tap opens the right product page, pre-filled with information the app already knows.<\/p>\n\n\n\n

This guide covers how to use deep links for cross-selling financial products. For fintech deep linking broadly, see deep linking for fintech and banking apps<\/a>. For product recommendations, see product recommendation deep links<\/a>.<\/p>\n\n\n\n

Why Deep Links Improve Cross-Sell Conversion<\/h2>\n\n\n\n

Without deep links, a cross-sell email or notification says "check out our new savings account" and opens the app's home screen. The user then has to navigate to products, find savings accounts, and figure out how to apply. Most do not bother.<\/p>\n\n\n\n

With deep links, the same message opens the specific product page, often pre-filled with the user's information and showing a personalized rate. The path from interest to action is one tap.<\/p>\n\n\n\n

Cross-Sell Scenarios<\/h2>\n\n\n\n
Checking to Savings<\/h3>\n\n\n\n
A user with a checking account but no savings account:<\/p>\n\n\n\n
{\n  "title": "Earn 4.5% APY on your savings",\n  "body": "Open a high-yield savings account and start earning on your balance",\n  "deep_link": "https:\/\/links.finapp.com\/products\/savings\/HY-SAVINGS",\n  "category": "cross_sell"\n}\n<\/code><\/pre>\n\n\n\n
Card Upgrade<\/h3>\n\n\n\n
A user with a basic card who qualifies for a rewards card:<\/p>\n\n\n\n
<p>Based on your spending, you could earn $480\/year in cash back\nwith the Platinum Rewards Card.<\/p>\n<a href="https:\/\/links.finapp.com\/products\/cards\/PLATINUM\/apply">\n  See Your Offer\n<\/a>\n<\/code><\/pre>\n\n\n\n
Loan Offer After Deposit History<\/h3>\n\n\n\n
A user with consistent direct deposits who may need a personal loan:<\/p>\n\n\n\n
{\n  "title": "Personal loan pre-approved",\n  "body": "You're pre-approved for up to $25,000 at 8.99% APR",\n  "deep_link": "https:\/\/links.finapp.com\/products\/loans\/PERSONAL-LOAN",\n  "category": "cross_sell"\n}\n<\/code><\/pre>\n\n\n\n
Insurance After Major Purchase<\/h3>\n\n\n\n
A user who just made a large purchase (car, electronics) might benefit from insurance:<\/p>\n\n\n\n
{\n  "title": "Protect your purchase",\n  "body": "Add purchase protection for your recent $1,200 transaction",\n  "deep_link": "https:\/\/links.finapp.com\/products\/insurance\/PURCHASE-PROTECT",\n  "category": "cross_sell"\n}\n<\/code><\/pre>\n\n\n\n
Timing Cross-Sell Deep Links<\/h2>\n\n\n\n
The timing of a cross-sell message matters as much as the content. Send recommendations when the user's behavior signals relevance:<\/p>\n\n\n\n

Implementation<\/h2>\n\n\n\n
Recommendation Engine Integration<\/h3>\n\n\n\n
The deep link itself is simple. The complexity is in deciding which product to recommend and when:<\/p>\n\n\n\n
func handleRecommendationDeepLink(_ url: URL) {\n    guard authManager.isAuthenticated else {\n        pendingDeepLink = url\n        showLogin()\n        return\n    }\n\n    let segments = url.pathComponents\n\n    \/\/ \/recommendations\/{rec-id}\n    if segments.count >= 3, let recId = segments.last {\n        let recommendation = recommendationManager.getRecommendation(recId)\n\n        guard let rec = recommendation else {\n            \/\/ Recommendation expired or already acted on\n            showRecommendations()\n            return\n        }\n\n        showProductDetail(rec.product, context: rec.personalizationContext)\n    }\n    \/\/ \/products\/{type}\/{product-id}\/apply\n    else if segments.contains("apply") {\n        let productId = segments[safe: 3]\n        let product = productManager.getProduct(productId)\n\n        guard let product = product else {\n            showError("This product is no longer available.")\n            return\n        }\n\n        \/\/ Pre-fill application with known user data\n        let prefill = userManager.getApplicationPrefill()\n        showApplication(for: product, prefill: prefill)\n    }\n    \/\/ \/products\/{type}\/{product-id}\n    else if segments.count >= 4 {\n        let productId = segments[3]\n        showProductDetail(productId)\n    }\n    \/\/ \/products\/{type}\n    else if segments.count >= 3 {\n        let productType = segments[2]\n        showProductCategory(productType)\n    }\n    else {\n        showRecommendations()\n    }\n}\n<\/code><\/pre>\n\n\n\n
Pre-Filling Applications<\/h3>\n\n\n\n
When a cross-sell deep link opens an application, pre-fill everything the app already knows:<\/p>\n\n\n\n
func getApplicationPrefill() -> ApplicationPrefill {\n    let user = currentUser\n\n    return ApplicationPrefill(\n        fullName: user.fullName,\n        email: user.email,\n        phone: user.phone,\n        address: user.address,\n        dateOfBirth: user.dateOfBirth,\n        ssn: nil, \/\/ Never pre-fill SSN, always re-enter\n        income: user.reportedIncome,\n        employmentStatus: user.employmentStatus,\n        existingProducts: user.activeProducts.map { $0.id }\n    )\n}\n<\/code><\/pre>\n\n\n\n
Pre-filling reduces application time from 5-10 minutes to 1-2 minutes, which significantly improves conversion.<\/p>\n\n\n\n

Cross-selling financial products is subject to regulatory scrutiny. The CFPB<\/a> has taken enforcement action against institutions that cross-sold products without clear consent. Every cross-sell deep link should:<\/p>\n\n\n\n
