.NET Development for Wealth Management Firms

Our financial analysis platform for a US wealth management SaaS delivered 100x faster data handling, winning interest from Franklin Templeton and Goldman Sachs. .NET development for wealth management firms is building FINRA-compliant, custodian-integrated software on .NET 8: API-first and auditable by design. Explore all industries we serve.

Why wealth management firms need custom .NET development right now

Wealth management firms face pressure from three directions at once: regulators, clients, and talent.

The SEC and FINRA have stepped up enforcement of electronic communications recordkeeping under Rule 17a-4. In 2022 and 2023, the SEC fined 16 broker-dealers a combined $1.8 billion for off-channel communications failures. Manual compliance workflows now carry real financial risk. Reg BI adds another layer: every client recommendation must include a documented best-interest determination at the time of advice. Paper trails and shared drives do not hold up under FINRA examination.

Client expectations have shifted. High-net-worth clients want portfolio dashboards that pull from Schwab Advisor Center, Orion, and Tamarac in real time. Manual reporting cycles that take three to five days frustrate clients and signal operational immaturity to prospects considering switching firms.

Advisors under 40 evaluate firms partly on the quality of internal tools. A firm running on disconnected spreadsheets and aging portals loses recruits to competitors who have invested in modern platforms.

Custom .NET development on .NET 8 addresses each problem: auditable data stores for compliance, unified dashboards for advisors, and documented APIs that connect Salesforce Financial Services Cloud, Orion, and Tamarac without brittle manual exports.

What we build for wealth management clients

QServices, a Microsoft Solutions Partner for Azure and Digital & App Innovation, builds five categories of .NET software for wealth management firms. Each addresses a specific operational or compliance problem:

• Client onboarding portals. Paper-heavy onboarding slows new accounts and frustrates advisors. We build .NET 8 portals that pull KYC data from Salesforce Financial Services Cloud, validate against compliance rules, and route approvals through a configurable workflow engine. Our Human-in-the-Loop (HITL) governance layer requires a compliance officer to approve any flagged application before it proceeds. No high-risk account moves forward on automation alone.
• Multi-custodian reporting engines. Consolidating positions across Schwab Advisor Center, Orion, and Tamarac is a data integration problem, not a display problem. We build ASP.NET Core APIs that pull from each custodian's API or file feed, normalize positions, and generate PDF or Excel reports with a single click. HITL checkpoints flag data mismatches for human review before reports reach clients.
• Communication archiving connectors. Under SEC Rule 17a-4 and FINRA recordkeeping rules, every advisor communication must be captured in non-rewritable storage. We build .NET microservices that archive email, SMS, and messaging-app communications and expose a compliance search API for examination readiness.
• Advisor productivity tools. We connect .NET APIs to Orion or Tamarac data to surface at-risk accounts, automate routine task reminders, and pre-populate meeting prep documents. Advisors make every client decision. The software surfaces the right information at the right time.
• Custom reporting APIs. For firms building their own front end, we deliver documented ASP.NET Core APIs with OpenAPI specs, SQL Server backends on Azure App Service, and CI/CD running from day one.

How a .NET development engagement actually works (step by step)

Most wealth management .NET projects run 8 to 24 weeks. Here is how our process works:

1. Discovery (Weeks 1-2). We interview your COO, Director of Operations, and Compliance Director. We document every system you integrate with (Salesforce, Orion, Tamarac, Schwab), every compliance constraint (Rule 17a-4, FINRA recordkeeping, Reg BI), and every workflow that is still manual. You receive a written scope document and a fixed-price or capped-time-and-materials estimate before development starts.
2. Architecture and database design (Weeks 2-3). Rohit Dabra, our CTO, reviews the data model before we write a single line of production code. This is where most wealth management software projects fail: mismatched account IDs across custodians, audit log gaps, and schema choices that require expensive migrations six months later. You approve the Entity Framework data model and the API contract before we build.
3. Core development (Weeks 3-16). We build in two-week sprints. Each sprint delivers working software, not mockups. Custodian API integrations (Salesforce, Orion, Schwab) come first because they carry the most delivery risk. HITL governance logic is wired into the workflow engine in sprint one, not added as an afterthought.
4. Compliance review and penetration test (Weeks 14-18). For SEC- or FINRA-regulated scope, we bring in a third-party compliance reviewer and penetration tester. This adds $5,000-$20,000 to the project budget and costs far less than a regulatory examination finding or a client data breach.
5. UAT and go-live (Weeks 16-22). Your team tests against real data in a staging environment. We resolve issues. We deploy to Azure App Service with a CI/CD pipeline that has been running since week one.
6. Maintenance retainer (ongoing). Most clients move to a $2,000-$4,000 per month retainer for security patches, bug fixes, and minor feature additions.

What this costs

A custom .NET project for a wealth management firm typically runs $25,000 to $130,000. Here is what moves the number:

Drives cost up:

• SEC Rule 17a-4 or FINRA compliance scope: add 15-25% to the base estimate
• Number of custodian integrations: each non-trivial connection (Schwab, Orion, Tamarac, Salesforce) adds $3,000-$12,000
• Third-party compliance review and penetration testing: $5,000-$20,000
• Custom multi-custodian data normalization engine
• HITL governance workflow with configurable approval routing

Keeps cost down:

• Limiting scope to one custodian in version one
• Using Azure App Service instead of custom infrastructure
• Phasing the project: onboarding portal first, reporting engine in phase two
• Reusing our pre-built .NET compliance middleware for FINRA recordkeeping

Our engineering rates run $35-$65 per hour depending on seniority. A medium-scope engagement (200-600 hours) lands between $8,000 and $30,000. A full platform build (600-2,000 hours) runs $30,000-$120,000.

Three things wealth management buyers usually get wrong

1. Treating reporting as a display problem. Most firms that come to us have tried fixing multi-custodian reporting by buying a better dashboard tool. The problem is almost always in the data layer: mismatched account identifiers across Schwab, Orion, and Tamarac; positions that do not reconcile because of timing differences; cost-basis data in three incompatible formats. A better UI just surfaces bad data faster. We spend the first sprint on the data model, not the front end.

2. Treating vendor portals as a technology strategy. Salesforce Financial Services Cloud, Orion, and Tamarac each offer their own client portal. Many firms bolt these together and call it a tech stack. Each portal has its own data model, its own permission system, and its own export format. When a client asks for a consolidated statement, someone manually re-enters data across three systems. A .NET API layer that sits behind all three eliminates that manual step permanently and creates a single audit trail that satisfies FINRA recordkeeping requirements.

3. Deferring compliance architecture to a later sprint. Every firm says it will add compliance logging later. Under SEC Rule 17a-4, records must be stored in non-rewritable, non-erasable format. Under Reg BI, a documented best-interest rationale is required at the time of advice, not reconstructed afterward. Retrofitting this costs three times what it costs to build it in from sprint one. We wire compliance middleware into the data access layer in the first sprint. It is not optional and it does not get deferred.

Recent work with wealth management and financial services clients

Our most relevant engagement is a US-based financial analysis SaaS (Analyst Intelligence) that needed to process large portfolio datasets in Excel and Google Sheets at enterprise scale. We delivered a 100x speed increase in data handling. The platform attracted interest from Franklin Templeton and Goldman Sachs against well-funded competitors. The data integration and performance challenges on that project directly mirror the custodian consolidation and reporting problems most wealth management firms face today.

We also built a cross-border payment reconciliation engine for Varipay (Jamaica), where .NET microservices cut transaction fees by 30% and reduced settlement times from 3-5 days to under 24 hours. The reconciliation architecture maps directly to multi-custodian position reconciliation in wealth management.

How long does .NET development take for a wealth management firm?

Most wealth management .NET projects run 8-16 weeks for a focused scope: a client onboarding portal, a single custodian API integration, or a compliance archiving connector. A full platform covering multi-custodian reporting, communication archiving, and advisor tooling typically runs 20-24 weeks. The main variable is integrations. Each custodian or CRM connection (Salesforce, Orion, Schwab Advisor Center) adds two to four weeks to the timeline.
