AutoRek vs Duco for cash, securities, CASS and regulatory reconciliation software

The verdict workload by workload

AutoRek vs Duco for cash and bank to ledger reconciliation

AutoRek is usually the better fit. Cash is where it started, and its own scale claims are cash claims: a largest deployment of 2.4 billion transactions and, by its account, a quarter of all cash transactions at UK banks. Bank statement to ledger matching with many to one grouping, charges, timing rules and sign-off is its daily work, and the control framework around the match is what its customers buy.

Duco reconciles cash well and many of its clients run cash next to positions. It reads any delimited or structured file, so MT940, camt.053 and BAI2 statements are not a problem. The question is proportion. If cash and bank to ledger is the whole brief, you are buying a general data automation platform to do one well understood job, and you should price it against dedicated cash reconciliation software and bank reconciliation software first. If nostro accounts dominate, add nostro reconciliation software to that comparison.

AutoRek vs Duco for securities reconciliation

Duco is usually the stronger choice for securities. Trade, position and holdings data arrive from custodians, prime brokers, administrators and internal books in formats that never quite agree, and Duco was designed so an operations analyst can load two unfamiliar files, describe the match in plain language and have a working reconciliation the same day. Its client list is weighted to firms where that is the daily problem.

AutoRek has moved into the same ground. It won the Waters award for best buy-side reconciliation platform in 2025, the year after Duco won it, and it opened a Miami office in June 2026 to sell to hedge funds and alternative managers. It fits best where the securities reconciliation feeds a regulatory or fund accounting control and the audit trail matters as much as onboarding speed.

AutoRek vs Duco for derivatives reconciliation

Duco usually wins. OTC derivative records are wide, with dozens of economic fields that differ by product, and they change whenever a counterparty or a regulator changes a template. A platform with no fixed schema absorbs that with a rule edit. AutoRek can reconcile derivatives data and will show you how, but its published references are in cash, client money and regulatory reconciliations, so ask for a derivatives reference at a firm your size before you treat it as equal. Gresham belongs on this shortlist too, for the reasons set out in Gresham vs AutoRek.

AutoRek vs Duco for CASS compliance

AutoRek is the clear choice for UK client money and client assets. The internal and external client money reconciliations, the resource and requirement calculation and the evidence a CASS auditor asks for are delivered as product, and safeguarding for payments and e-money firms follows the same pattern. This is the work AutoRek is hardest to displace from.

Duco can run CASS reconciliations as well, because the matching itself is ordinary. The difference is who owns the rulebook. In Duco your team builds and maintains the client money logic on a general platform. In AutoRek the logic arrives with the product and the vendor maintains it as rules change. US buyers should note that neither markets an equivalent for SEC customer protection or for a depository institution's own settlement accounts.

AutoRek vs Duco for regulatory reporting and controls

The two come at regulatory work from opposite ends. AutoRek sells regulatory reporting as a product line (RegToolKit) on top of its reconciliation engine, so the report, the reconciliation behind it and the sign-off sit in one place. Duco is used upstream of the report: it proves that trade and transaction data agree across systems before submission and catches breaks in the pairing and matching fields regulators check.

For controls, look at how each one records a decision. AutoRek is built around a control framework with defined approval steps. Duco gives every rule change and exception an audit trail and, since May 2026, markets an agent layer that prepares data and triages exceptions, with ten firms reported live at launch. If an auditor will ask who approved a rule and when, ask both vendors to show that screen with your own example.

Build speed, agents and who does the work

This is Duco's main argument and it is a fair one. Its Natural Rule Language lets a business user write a matching rule in near plain English, and the Agentic Rule Builder it launched at Sibos in September 2025 proposes rules from the data. A new reconciliation does not need a vendor project. For a firm with hundreds of small, changing reconciliations, that changes the economics.

AutoRek is more often delivered as an implementation. Third-party reviews mention a steep learning curve and a substantial setup project, and in exchange you get a tightly governed result. Neither model is wrong. A firm with five very large, stable, regulated reconciliations is well served by AutoRek. A firm with five hundred small ones is better served by Duco. The matching concepts both rely on are described on transaction matching software.

Deployment, security review and ownership

Duco is multi-tenant cloud and nothing else. That keeps upgrades simple and is a blocker for any institution with a policy that reconciliation data stays in an environment it controls. AutoRek offers private cloud, a SaaS product called Grath and an embedded product called Topa for firms that want its engine inside their own service.

Either way your third-party risk team will ask for the vendor's audit reports, penetration test summary and subprocessor list before a contract is signed. If your own institution keeps its SOC 2 evidence in a compliance tool, add the vendor review there as a control, so the renewal does not restart the questionnaire from nothing. On ownership, AutoRek has been an independent Glasgow company for more than 30 years with its US headquarters in New York, and Duco is London based and has been majority owned by the private equity firm Nordic Capital since 2021.

Pricing for AutoRek, Duco and a bank-side option

Neither vendor publishes a price list. Both quote on volume, number of reconciliations or processes, modules and deployment, and AutoRek scopes implementation separately. The only fair comparison is two written quotes on your own volumes, for the same term and the same list of reconciliations, with license and services on separate lines. Ask Duco what happens to the price when daily record volume doubles, and ask AutoRek for the day rate and the number of days.

BankAutomation publishes its plans. Operations is $1,200 a month for 250,000 matched items and three sources. Platform is $3,900 a month for 2,000,000 items, unlimited sources, SSO and maker-checker approvals. Institution is $9,500 a month, and Enterprise is $14,900 a month for private or VPC deployment. Annual billing halves each monthly rate, and every limit is on the pricing page. It does not replace either product for securities, derivatives or client money. It is the cheaper home for daily cash settlement at a bank.

Where a US bank or credit union fits

A US community or regional bank that asks this question usually has a small securities workload and a large daily settlement one: ACH against FedACH windows, card and ATM networks, FedNow and RTP, the Fed account, correspondents and suspense. AutoRek and Duco can each be configured for that work. Neither arrives knowing it, and both are priced for something harder.

The arrangement that costs least is a split. Use AutoRek or Duco for securities, client money or regulatory data if you have it, and run settlement accounts on a platform built around US rails: ACH reconciliation software, instant payments reconciliation software and Federal Reserve account reconciliation software describe that work account by account.

How to choose in four steps

Questions buyers ask

Is AutoRek or Duco better for financial institutions?

Neither is better for every institution. AutoRek is usually stronger for cash, bank to ledger, CASS, safeguarding and regulatory reconciliations, and it offers private cloud. Duco is usually stronger for securities, derivatives and firms that want operations staff to build reconciliations themselves, and it is cloud only. Choose by your largest group of reconciliations and confirm with a reference in your segment.

How does AutoRek compare with Duco for bank to ledger reconciliation?

AutoRek is usually the stronger fit for bank to ledger work. It was built around financial control and high volume cash matching, with sign-off inside a control framework. Duco reconciles bank statements against a ledger competently but is a general data automation platform, so a buyer whose whole requirement is bank to ledger should also price dedicated bank reconciliation software.

Is Duco or AutoRek better for cash reconciliation?

AutoRek is usually better for cash reconciliation at volume, and its largest published deployment is 2.4 billion transactions. Duco is a good choice when cash is one of many reconciliations a team wants on a single self-service platform. For a US bank's ACH, card and Fed settlement cash, neither publishes references, and a bank-side platform is usually cheaper.

How much do AutoRek and Duco cost?

Both are quote only, with no published price list. Quotes depend on volume, the number of reconciliations or processes, modules and deployment, and AutoRek implementation is scoped separately. Get both quotes on the same reconciliation list and term. For daily bank settlement work, BankAutomation publishes plans from $1,200 a month.

What are the alternatives to both?

Gresham and SmartStream for trade and securities data, Xceptor where documents sit beside reconciliation, FIS Data Integrity Manager for very large estates, and ReconArt, Trintech and BankAutomation for bank-side settlement and close work. Each vendor has its own page, AutoRek alternatives, Duco alternatives and Xceptor alternatives, and our reconciliation software comparison for banks lists 16 options with prices.
