Addepar and SEI Archway both serve family offices that need consolidated reporting, investment data aggregation, performance visibility, and secure stakeholder reporting. The right choice depends on whether your office needs an analytics-first reporting platform or an accounting-first family office operating platform.

One naming note matters. Buyers still search for “SEI Archway,” but SEI announced on July 1, 2025 that Aquiline completed its acquisition of SEI’s Family Office Services business. Effective June 30, 2025, the business operates under the name Archway and provides integrated technology and outsourced services for accounting, investment management, and reporting needs. This article uses “SEI Archway” for search clarity and “Archway” for the current product name.

Addepar is stronger when your office needs multi-asset analytics, complex ownership reporting, real-time custom reports, alternatives document workflows, flexible APIs, and stakeholder-friendly portfolio views. Its family office page emphasizes a complete view across accounts, asset classes, legal entities, and currencies, plus analysis across complex ownership structures and multi-currency scenarios.

Archway is stronger when your office needs core general ledger, investment data aggregation, partnership accounting, bill pay, entity-level accounting workflows, report packages, a client portal, and optional outsourced services. Archway’s family office page positions the platform around accounting, investment data aggregation, reporting, partnership accounting, bill payment, and outsourced services for single and multi-family offices.

One more point belongs near the top: add FundCount to the shortlist when the buying requirement is accounting-grade reporting plus portal publishing from the same workflow. FundCount positions its family office solution around portfolio accounting, partnership accounting, general ledger, reporting, investor portal, and data aggregation. Its Single Family Office pricing starts from $34,099 per year, with digital transformation and hosting fees applying separately.

Key takeaways

Quick comparison table

*Sources for this table include current Addepar family office, alternatives, and integrations pages, current Archway family office and client portal pages, and SEI’s 2025 acquisition announcement.

Bottom line

Addepar is the better option for family offices that need analytics-led portfolio reporting. It is a stronger fit when the hard problem is consolidating portfolio data across asset classes, entities, currencies, managers, and alternatives, then turning that data into custom reports and stakeholder views.

Archway is the better option for family offices that need accounting and reporting operations in one platform. It is a stronger fit when the office needs general ledger, partnership accounting, bill pay, nested ownership, report packages, client portal delivery, and the option to outsource part of the back office.

FundCount belongs on the shortlist when reporting must reconcile to the books and portal delivery must come from the same workflow. FundCount is not an Addepar clone or an Archway clone. It is the third option to evaluate when portfolio accounting, partnership accounting, general ledger, reporting, and investor portal delivery need to sit in one accounting-backed environment.

Detailed comparison

1) Core positioning

Addepar

Addepar positions itself as a data and AI platform for investment professionals. Its family office page says it centralizes financial information and provides a complete view of accounts and assets across asset class, legal entity, and currency.

That makes Addepar a strong fit when the office needs analytics, reporting, alternatives workflows, and a modern stakeholder experience. It is less centered on running entity books.

SEI Archway, now Archway

Archway positions itself around accounting, investment data aggregation, reporting, and services for family offices and financial institutions. Its homepage says the platform brings together accounting detail and investment data to deliver comprehensive financial reporting, with integrated GL, partnership accounting, account aggregation, and investment performance.

That makes Archway a stronger fit when accounting operations and reporting operations need to live together.

Practical takeaway

Choose Addepar when portfolio analytics and reporting are the primary problem. Choose Archway when accounting, reporting, and back-office operating workflows are the primary problem.

2) Accounting depth and general ledger

Addepar

Addepar is not positioned as a family office general ledger on the public pages reviewed here. Its public family office positioning focuses on data centralization, portfolio analysis, custom reporting, alternatives document workflows, scenario modeling, billing, security, portal access, and mobile apps.

That does not make Addepar weak. It means buyers should confirm where entity books, journal entries, reconciliations, and formal financial statements will live.

Archway

Archway is built around accounting depth. Its family office page says the platform bridges accounting and investment teams, provides a single source of reporting data, supports a custom multi-currency chart of accounts, automates close processes, and creates journal entries for investment activity, cash management, treasury, bill payment, and partnership tracking.

Archway also supports complex capital movements, intercompany activity, securities transfers, equity transfers, bill pay, expense reporting, approval structures, and multi-level budgets.

Practical takeaway

Archway is the stronger accounting platform. Addepar is the stronger analytics and reporting platform. If you already have a trusted accounting core, Addepar may fit well. If the platform must run the books, Archway deserves more weight.

3) Data aggregation and multi-entity reporting

Addepar

Addepar gives users a complete view of accounts and assets across asset class, legal entity, and currency. It also says users can analyze complex ownership structures, multi-asset classes, and multi-currency scenarios down to transaction-level detail.

This fits family offices that need reporting flexibility across entities, branches, managers, currencies, and asset classes.

Archway

Archway emphasizes direct data integrations with custodians, brokerage firms, banks, and enrichment sources, plus flexible APIs. It also supports sophisticated family office ownership structures, including master-feeder, fund-of-funds, and nested entities, with look-through reporting across individuals, households, and generations.

Archway also consolidates data across entities, asset classes, custodians, managers, currencies, and geographies.

Practical takeaway

Both platforms support complex data aggregation and reporting. Addepar is stronger when the reporting layer needs flexible analytics. Archway is stronger when aggregation needs to feed accounting, GL, bill pay, partnership tracking, and scheduled family reporting.

4) Alternatives and private assets

Addepar

Addepar’s Alts Data Management product automates alternative investment document collection, processing, validation, storage, and reporting workflows. Addepar says documents can be uploaded manually or collected from fund administration portals and inboxes, and processed documents are saved in the file center.

This matters for family offices with private equity, venture capital, hedge funds, real estate, direct deals, and capital-call-heavy workflows.

Archway

Archway tracks complex investment types, including equities, bonds, cash, hedge funds, private equity, and personal assets. Its client portal page also says the document manager can deliver partnership agreements, account records, and alternative investment statements.

Archway’s outsourced services also include partnership accounting and administration, including income and expense allocations, capital transactions, partner book values, tax values, disparity account values, and reporting.

Practical takeaway

Addepar is stronger if the main alternatives bottleneck is document-to-data workflow for reporting and analytics. Archway is stronger if the alternatives workflow must connect to partnership accounting, capital transactions, and formal family office accounting.

5) Reporting and report-pack workflows

Addepar

Addepar’s family office page says users can create customized multigenerational reports that update in real time. It also offers custom reports and stakeholder access through a portal and mobile apps.

This is valuable for offices that need report variations for principals, trustees, advisors, children, investment committees, and accountants.

Archway

Archway offers a highly configurable report library with 200+ report templates, including financial statements, asset allocation, investment activity, performance, and risk reports. It also supports recurring and ad hoc report packages for internal staff and family members.

Archway can measure investment, portfolio, and manager performance for individuals, households, and user-defined groups using time-weighted or money-weighted returns, benchmarks, and user-defined allocation models.

Practical takeaway

Addepar fits analytics-driven reporting teams that need flexibility and real-time views. Archway fits operations teams that need repeatable report packages tied to accounting, performance, and family office workflows.

6) Client portal and stakeholder experience

Addepar

Addepar’s family office page says it offers a customizable portal for lawyers, accountants, and other stakeholders, plus mobile and iPad apps for family members to access portfolios securely.

This fits offices that want modern stakeholder access around portfolio reporting.

Archway

Archway’s client portal gives clients on-demand access to financial information across devices. It includes interactive dashboards, customizable data views, organized document storage, net worth, performance, allocation, account balance, expense, and cash summary views.

The portal also supports document storage for report packages, partnership agreements, account records, and alternative investment statements. It includes custom branding and client-specific layouts.

Practical takeaway

Addepar’s portal fits analytics-led portfolio reporting. Archway’s portal fits family office reporting delivery that includes dashboards, consolidated net worth, documents, and report packages.

7) Services model and operating support

Addepar

Addepar offers onboarding support, a help center, online training, and implementation expertise. Its family office page references nearly a decade of client implementations and on-demand training resources.

Addepar is best evaluated as software plus implementation support, not as a back-office outsourcing model.

Archway

Archway is built around a flexible technology and services model. Its client portal page says clients can use the platform in-house, outsource back-office work to Archway Family Office Services, or use a hybrid model.

Archway’s family office page also lists outsourced services for portfolio reconciliation and consolidated reporting, bill payment and expense reporting, and partnership accounting and administration.

Practical takeaway

Choose Archway if the office wants technology plus operational support. Choose Addepar if the office has internal operations and wants a stronger analytics and reporting layer.

8) Integrations and API posture

Addepar

Addepar’s integrations page says direct data feeds aggregate portfolio, market, and client data across liquid and illiquid assets. It also offers pre-built partner integrations and flexible APIs for custom integrations with in-house or third-party systems.

This fits family offices with internal data teams, warehouses, custom reporting workflows, or a broader wealthtech stack.

Archway

Archway supports automated direct feeds with custodians, brokerage firms, banks, and enrichment sources, plus flexible APIs. Its platform also consolidates financial data across entities, asset classes, custodians, managers, currencies, and geographies.

Archway’s integration story should be tested against accounting workflows, bill pay, partnership administration, portal delivery, and outsourced services.

Practical takeaway

Addepar is stronger for open analytics and custom data workflows. Archway is stronger when integrations need to feed a GL-centered family office operating model.

9) Security and controls

Addepar

Addepar’s family office page says the platform uses a multifaceted data security program and protects family office data. The same page references role-based access control and encryption at rest and in transit in its page imagery, and the platform includes stakeholder portal access.

Buyers should request SOC reports, penetration testing summaries, data retention policies, access-control documentation, and incident response materials during diligence.

Archway

Archway’s client portal describes itself as a bank-grade reporting tool for sharing consolidated wealth information securely. It also supports secure document storage and configurable client access.

Buyers should ask Archway to show user permissions, approval workflows, portal access controls, data export controls, audit logs, and service-team access governance.

Practical takeaway

Both vendors require a formal security review. The product demo should show permissions by entity, household, advisor, accountant, and internal user role.

10) Pricing and implementation

Addepar

Addepar does not publish standard pricing on the pages reviewed here. Expect pricing to reflect users, data complexity, assets and accounts, alternatives workflows, integrations, reporting scope, portal needs, and implementation requirements.

Implementation effort depends on custodial feeds, entity modeling, account mappings, alternatives workflows, report design, portal setup, permissions, and integrations.

Archway

Archway does not publish standard pricing on the pages reviewed here. Expect pricing to reflect platform scope, data complexity, entity count, report packages, portal setup, service model, bill pay, partnership administration, and outsourcing needs.

Implementation effort depends on chart of accounts, entity structures, historical data, data feeds, report library configuration, bill pay rules, partnership accounting setup, client portal rollout, and service model design.

Practical takeaway

Compare total cost with the same operating scope. Include software, implementation, historical migration, data feeds, report design, portal setup, training, services, ongoing support, and internal staff time.

FundCount as a third option

FundCount’s family office pricing page positions the product as an all-in-one solution for single family offices that need to consolidate, monitor, and report investment information across family entities. It also lists support for data feeds from custodians, brokers, banks, and alternative managers, plus full financials, reconciliations, and financial statements.

Choose FundCount when final reports must reconcile back to accounting records and when portal delivery needs to stay close to the books.
