How we make this list: we compare pricing pages, product documentation and public user reviews. Rankite is independent; if a vendor ever pays for a featured spot, that listing is clearly labeled Partner.
Key takeaways
- Independent RIAs that want one platform for accounting, reporting, billing and trading usually land on Orion or Envestnet Tamarac.
- Family offices and UHNW advisors with complex entity structures fit Addepar, Masttro, Archway or FundCount, where accounting depth matters more than breadth of advisor tools.
- SS&C Black Diamond Wealth Solutions (formerly the Black Diamond Wealth Platform) suits firms that want portfolio accounting inside a wider SS&C technology stack.
- SS&C Advent and Croesus serve institutional and Canadian advisor markets respectively, with long track records in performance accounting.
- Every tool here sells on quote with implementation projects, so budget for onboarding time, not just the license.
Portfolio accounting software is the system of record for an advisory firm or family office. It ingests positions and transactions from custodians, reconciles them, calculates performance, generates client reports and often handles billing. Pick the wrong one and your operations team spends every morning fixing breaks. Pick the right one and reconciliation happens before the market opens.
This category splits by audience. Advisor platforms like Orion, Envestnet Tamarac and SS&C Black Diamond Wealth Solutions bundle accounting with reporting, billing, trading and client portals for RIAs and broker-dealers. Family office platforms like Addepar, Masttro, Archway (the former SEI Archway) and FundCount go deeper on complex ownership structures, partnerships and alternative assets. Institutional tools like SS&C Advent serve asset managers with fund-level accounting needs.

The best portfolio accounting software
Starting priceSee website
Free planNo
Addepar built its name on a hard problem: representing a family's entire financial picture, from listed securities to private funds, real estate and direct investments, in one consistent data model. For family offices and advisors to ultra-high-net-worth clients, that unified view is the product. The platform aggregates portfolio, market and client data and layers performance reporting and AI-assisted analysis on top.
The tradeoff is that Addepar is not a small-firm tool. Pricing is custom, onboarding takes months, and firms below a certain asset scale will find the cost hard to justify. For the complex end of the market, though, few platforms model ownership structures as completely.
What we like- Handles complex portfolios across public and private assets in one view
- Large integration ecosystem
- Strong data aggregation
Watch out for- Pricing is quote-based and aimed at larger firms
- Implementation is a serious project

The Black Diamond Wealth Platform is now SS&C Black Diamond Wealth Solutions, after SS&C unified its wealth offerings under that brand. The product itself remains a portfolio accounting and reporting platform aimed at RIAs and wealth managers, with an emphasis on clean client reporting and integrations across the SS&C ecosystem, including Advent products and other SS&C tools.
Firms already running SS&C software get the most from it, since data flows between the pieces without custom integration work. Standalone, it competes with Orion and Tamarac on reporting quality and ease of use. Pricing is quote-based, as with everything in this category.
What we like- Modern reporting and client experience
- Integrates with the wider SS&C stack
- Large advisor user base
Watch out for- Best value comes with other SS&C products
- Customization has limits compared to bespoke platforms
#3
Orion
Best for: Independent RIAs wanting an all-in-one stack
Visit orion.com
Starting priceSee website
Free planNo
Orion holds the top market share for portfolio accounting and reporting in the advisor channel, and the reason is completeness. Beyond accounting and performance reporting, the platform includes fee billing, household-level rebalancing and trading, a client portal, and data warehousing. It connects directly to major US custodians and reconciles positions overnight so reports are ready before the market opens.
That depth makes Orion the default shortlist entry for independent RIAs from solo practices to large enterprises. The honest catch is that adopting the full stack is a multi-month project, and firms that only need accounting may pay for modules they never open. Orion also stacks up well against Black Diamond on integration depth and against Addepar on breadth of advisor-channel fit.
What we like- Number one market share in advisor portfolio accounting
- Reconciles custodian data overnight
- Deep stack including CRM, trading and compliance
Watch out for- The breadth of the stack can mean a long rollout
- Pricing reflects the enterprise positioning
#4
Envestnet Tamarac
Best for: RIAs needing deep portfolio accounting plus rebalancing
Visit envestnet.com
Starting priceSee website
Free planNo
Tamarac is Envestnet's portfolio accounting and rebalancing suite for RIAs. The accounting engine covers billing, performance reporting and data warehousing, while the trading and rebalancing tools are among the strongest in the advisor channel. Tax management features like wash sale detection matter at tax time for taxable accounts.
Firms already using Envestnet products get natural integration benefits. Evaluated standalone, Tamarac's edge over Orion is rebalancing depth; its weakness is that parts of the interface show their age. Pricing is quote-based and typically tied to assets or users.
What we like- Strong rebalancing and trading alongside accounting
- Part of the large Envestnet ecosystem
- Good tax management tools
Watch out for- Interface feels dated in places
- Best as part of a broader Envestnet relationship
#5
SS&C Advent
Best for: Institutional asset and wealth managers
Visit advent.com
Starting priceSee website
Free planNo
SS&C Advent is the veteran of this list. Products like Advent Portfolio Exchange (APX) and Geneva have handled portfolio management and accounting for institutional asset managers and hedge funds for decades. The accounting is exact, the reporting is flexible, and the installed base is enormous.
That history is also the weakness. Some Advent products carry legacy architecture, and implementations are measured in quarters, not weeks. Firms choose Advent when they need proven institutional-grade accounting and plan to stay for a decade. Faster-moving RIAs usually prefer Orion or Black Diamond.
What we like- Decades-long track record in institutional accounting
- APX and Geneva cover a wide range of firm types
- Deep SS&C support resources
Watch out for- Legacy architecture in places
- Implementations are long and expensive

Croesus has served Canadian wealth management firms since 1987, and that specialization is the point. The platform covers portfolio management, performance reporting, rebalancing and compliance with the specifics of the Canadian market built in. Its acquisition of rebalancing software iBalance strengthened the trading side.
US firms can use Croesus but will find the data feeds and compliance content tilted north of the border. For Canadian advisors, that same tilt is the reason to choose it over a US platform with a Canada afterthought. Pricing is quote-based.
What we like- Deep expertise in Canadian advisor workflows
- Portfolio management plus rebalancing
- Strong compliance tooling
Watch out for- US-focused firms will find the coverage thinner
- Smaller partner ecosystem than US leaders
#7
FundCount
Best for: Family offices needing true general-ledger accounting
Visit fundcount.com
Starting priceSee website
Free planNo
FundCount takes an accountant's approach to portfolio software: every transaction posts to a true double-entry general ledger, so performance and holdings reports always tie to the books. That matters for family offices, fund administrators and investment partnerships that need financial statements, capital accounts and tax forms like K-1s alongside investment reporting.
The product is less polished than Addepar or Masttro on the client-experience side, and the company is smaller, which shows in the integration catalog. Firms that prioritize accounting precision over presentation usually accept that tradeoff gladly. Pricing is quote-based.
What we like- Real double-entry general ledger under the portfolio views
- Strong partnership accounting and K-1 support
- Multi-currency and multi-entity depth
Watch out for- Interface is utilitarian
- Smaller company with a narrower integration list
#8
Masttro
Best for: UHNW families with complex global balance sheets
Visit masttro.com
Starting priceSee website
Free planNo
Masttro is built for the complexity of ultra-high-net-worth estates: multiple entities, currencies and countries, plus private markets, real estate and collectibles alongside traditional holdings. The platform connects directly to hundreds of global custodians rather than relying on screen scraping, which matters for data reliability and security.
The audience is narrow by design. This is wealth technology for families and the professionals who serve them, not a general advisor platform. Firms in that segment get a purpose-built balance-sheet view; everyone else will find better value in the advisor-focused tools above.
What we like- Consolidates liquid and illiquid holdings, liabilities and passion assets in one view
- Direct custodian connections
- Strong privacy and security posture
Watch out for- Aimed squarely at the ultra-wealthy segment
- Pricing reflects that positioning

Archway is the new name for what was SEI Archway, after Aquiline acquired SEI's Family Office Services business in mid-2025 and spun it out as an independent company. The Archway Platform itself is unchanged in concept: integrated accounting built around a centralized general ledger, covering partnership, portfolio and corporate accounting with performance reporting, bill payment and a client portal.
The differentiator is the services option. Family offices that do not want to run accounting operations in-house can outsource them to Archway's team on the same platform. With the ownership change still fresh, prospective clients should ask about the product roadmap during evaluation, but the installed base and asset scale speak to the platform's staying power.
What we like- Proven general-ledger-based accounting engine
- Optional outsourced accounting services
- Long history with large family offices
Watch out for- Recent ownership change to evaluate
- Enterprise onboarding timelines
How we chose
We verified each vendor's current name and website first, because this category has seen real consolidation: Black Diamond is now SS&C Black Diamond Wealth Solutions, SEI Archway is now the independent Archway Group, and Backstop Solutions was absorbed into ION Analytics, so we replaced it with Croesus. We checked product pages and recent company announcements for what each platform actually covers today. Pricing is quote-based across the category, so all entries show "See website" rather than third-party estimates. We weighted accounting depth, reconciliation quality, reporting flexibility and fit for the stated audience of each product.
What to verify before you sign
Reconciliation is the first thing to test. Ask which custodians connect directly, how breaks are surfaced, and what time reconciled data is available each morning. A demo with your own accounts, not sample data, answers this in a week.
Second, map your entity structures. If you run partnerships, trusts or multi-entity families, confirm the platform models them natively rather than through workarounds. FundCount and Archway lead here; advisor platforms vary.
Third, price the whole project. Licenses are only part of the cost. Implementation, data conversion, training and ongoing support can match the first year's license fees. Get all of it in writing, including what happens to your data if you leave.
Common mistakes in this purchase
The classic error is buying for reporting screenshots and discovering the accounting underneath cannot handle your structures. Pretty client reports mean nothing if the operations team reconciles by hand every morning. Evaluate the ledger first, the reports second.
Another is underestimating conversion. Moving years of transaction history from a legacy system is the longest phase of most implementations. Start the data conversation in the first demo, not after signing.
A third is ignoring the services question. Some firms want software they run themselves; others want the vendor to run the back office. Archway, Orion and several others offer managed options. Decide which model you want before comparing vendors, because it changes the shortlist.
Frequently asked questions
How much does portfolio accounting software cost?
Vendors in this category sell on custom quotes, usually tied to assets under administration, account counts or users. Expect five to six figures annually for advisor platforms and more for institutional or family office systems, plus implementation fees.
What is the difference between portfolio accounting and portfolio management software?
Portfolio accounting is the system of record: positions, transactions, reconciliation, performance calculation and reporting. Portfolio management adds decision tools like rebalancing, trading and modeling. Most products on this list do both, but their accounting depth varies.
Can small RIAs use these platforms?
Yes. Orion, Envestnet Tamarac and SS&C Black Diamond Wealth Solutions all serve firms from solo practices upward. The family office and institutional tools are generally priced for larger operations.
How long does implementation take?
Anywhere from a few weeks for a simple RIA setup to six months or more for complex family offices with data conversion. Ask for a reference client with a similar profile and timeline.
Do these platforms handle alternative investments?
Most do, with varying depth. Addepar, Masttro, Archway and FundCount are strongest on private funds, real estate and complex ownership structures. Confirm your specific asset types during evaluation.
What happened to SEI Archway and Black Diamond?
SEI's Family Office Services business, including the Archway Platform, was acquired by Aquiline in 2025 and now operates independently as Archway. Separately, SS&C unified its wealth offerings, including the Black Diamond Wealth Platform, under the SS&C Black Diamond Wealth Solutions brand.
