5 Best Virtual Accounting Software in 2026 for Banks Holding Municipality Deposits

Public funds are the only specialty deposit where the price of holding the money depends on how healthy your bank is. In Florida, a Qualified Public Depository pledges collateral in tiers of 25%, 50%, 110% or 150%, keyed to its own financial condition rating. In Ohio, the standard is 102% of uninsured public deposits, though the Treasurer may approve a rate as low as 50% for a well-run institution. Same deposit, same depositor, up to six times the collateral, depending on who's holding it.

That's the structural fact that makes this vertical different, and why "we'll beat their rate" is usually the wrong opening. The bank that wins a municipal relationship in 2026 is the one that makes collateral reporting, fund-level accounting and bond-proceeds tracking disappear as a problem for a finance director with a GASB deadline and no staff.

The market is large and moving. State and local governments held $773.0 billion in currency and deposits as of Q1 2026 (Federal Reserve Z.1). There are 91,438 local governments as of 2025, with all net growth coming from special districts, up 644 to 40,199, the hardest sub-accounting case there is. Municipal bond issuance set a 2025 record at $579.9 billion, new money up 19.3% to $430.1 billion, meaning record construction draw balances are sitting in banks right now. With the fed funds rate at 3.63% in August 2026, those balances are worth competing for.

Below are the five platforms that do this work for a bank, two adjacent product categories worth knowing about, and what it costs to keep doing it by hand.

What the software has to do

Integration with the entity's own accounting system. Municipal relationship managers name this as the single strongest signal: what lands is the bank's system talking directly to the government's own ERP, Tyler, Springbrook, Caselle, OpenGov, or a direct pattern like Sage or Munis. Ask any vendor which ERPs actually live today.

Fund- and department-level sub-accounting, at the entity count public bodies actually have. A single county can carry general fund, debt service, capital projects, enterprise, grant, and trust and agency funds, each its own legal entity, before special districts, the fastest-growing category, add dozens more.

Interest allocation across funds and bond issues. Each fund owns its own earnings; each bond issue owns its own earnings, separately, for arbitrage rebate purposes.

Compliance monitoring and audit-ready reporting. Three things the software has to track: collateral value against balances daily, not just the monthly filing, since a rate move can create a shortfall with no deposit activity at all; permitted investments, enforced against both the state list and the entity's own stricter policy; and the GASB 40 disclosures a finance director needs every year, ideally as a standing report instead of a fire drill.

How we evaluated

1. ERP integration. Which municipal general ledgers are live today — Tyler, Springbrook, Caselle, OpenGov, CentralSquare, Workday, or a direct pattern like Sage or Munis — and for which named bank, versus which are pattern-only.

2. Fund- and issue-level sub-accounting. Sub-accounting at the entity counts public bodies actually have: general fund, debt service, capital projects, enterprise, grant, and trust and agency, plus special districts, and a separate sub-account per bond issue where a capital programme requires it.

3. Interest allocation, per fund and per issue. Each fund's earnings tracked to that fund, each issue's earnings to that issue. And the operational half of the same requirement: a dated draw ledger mapped to the §148 milestones, with disbursement gated on the indenture's own certifications, since per-issue earnings are only provable against a per-issue spend history.

4. Compliance monitoring and reporting. Collateral watched on both legs — balances and pledged-securities market value, daily, not just against the filing calendar; permitted-investment enforcement against both the state list and the entity's own stricter policy; GASB 40 outputs produced on a schedule rather than on request.

We’re also looking into whether money moves from a sub-account on the bank's own rails or needs a second platform. Pricing didn't factor in, since almost nobody in this category publishes it.

Comparison at a glance

Bottom line. Hudson when the book has real fund depth, active bond issues, and disbursement that has to happen without a second platform. ZSuite is the safest buy on deployed footprint. Infinant names the vertical and has the strongest published rails, with nothing published on funds or collateral. Agiletics is close to free on an existing Jack Henry contract, though municipal isn't documented and it doesn't move money. A DDA per fund still works.

The five platforms

1. Hudson

Best for banks with real fund depth, multiple districts, or an active bond issue in draw.

Founded 2020, New York. Sells a virtual account and specialty deposit platform to US banks, white-labeled under the bank's brand, across six modules: Virtual Account Management, Contract Intelligence, Payment Processing, a Rules Engine, Approval Workflows and Client Portals.

The structural fit is the multi-tier sub-ledger: one master per public body, a sub-account per fund, and, where a capital programme requires it, a sub-account per bond issue. Sub-accounts are routable, so a tax remittance or grant drawdown posts against the right fund instead of landing in the master. Each sub is independently tracked with its own interest allocation, worth pressing every vendor on, since it's what a per-issue arbitrage rebate calculation actually requires and almost nobody publishes. Reconciliation between sub-ledger and core runs near-real-time, producing a dated, per-issue draw history that ties to the milestones without anyone reconstructing it from statements. Money moves from a sub-account on the bank's own rails: ACH, wire, RTP, FedNow and check.

What to check: which municipal ERP integrations are live today, for which named bank, versus which are pattern-only. And footprint: ZSuite has 150+ live institutions and published municipal results; Hudson's live base is smaller.

2. ZSuite Technologies (ZEscrow)

Spun out of Leader Bank in 2019. 150+ financial institutions, NPS of 88, both SOC 2 Type II and SOC 1 Type II. Named deployments: Kearny Bank, Coastal Community Bank, Core Bank. A May 2026 post gives the category's two most useful public numbers: average municipal deposit of $280,000 against a $191,000 platform average, and a $10 billion New Jersey bank growing municipal deposits to $86 million in twelve months. Sub-accounts carry unique numbers.

What to check: the municipal material doesn't mention ERP integration, fund-level interest allocation, or collateral at all, the vertical's defining constraint. Structurally it's a holding-account model, with disbursement routed through its Onbe partnership rather than the bank's own rails.

3. Infinant

Best for public funds inside a broader platform strategy.

Charlotte, NC; the Interlace platform sits above a legacy core. $15M Series A, December 2024. Named customers: Valley Bank, Live Oak Bank, Legend Bank. Municipalities are a named vertical, and the rails are direct: ACH, wire, FedNow straight to the Fed.

What to check: an immutable ledger with no fund-level methodology published. No ERP integration named, no interest allocation detail, no collateral reporting, no quantitative municipal metrics anywhere. No check disbursement either, a real omission for vendor AP. A virtual account gets its own account number but not its own routing number.

4. Jack Henry (Agiletics Escrow System)

Best for banks already on a Jack Henry contract.

Founded 1987, JH-owned since 2018. Core-agnostic, supports interest accrual and sharing, and state-specific processing.

What to check: it's an accounting system, not a money-movement system, so draws, payroll and AP happen in a separate cash management platform. No documented ERP integration, no single sign-on from digital banking, and municipal handling specifically is undocumented. JH's September 2025 Victor Technologies acquisition doesn't mention public funds or municipal in its named capabilities, and no sunset for Agiletics has been announced either way.

Your other competitor is the software the city already runs

Tyler Technologies, the incumbent government ERP, is moving into payment processing directly. Q4 2025 revenue was $575.2 million, up 6.3%, with transaction revenue of $196.7 million, up 12.1%. In January 2026, Tyler became the sole payment processor for Chesterfield County, VA (roughly 400,000 residents), unifying payments across county departments including treasury operations. When the ERP owns processing and reconciliation, the bank's remittance and lockbox economics are directly exposed, which is exactly why ERP integration ranks ahead of the sub-ledger itself.

Paymentus (fiscal 2025 revenue $1.2B, up 37.3%) sells to banks and competes with them in the same breath through a dedicated banking offering. On the ERP side, OpenGov (Cox Enterprises investment, $1.8B valuation) serves ~1,900 agencies; Springbrook serves 2,800+, and its own 2026 survey found 54% of local governments still run "Frankensuites" of stitched-together systems, a fair description of what a banker walks into.

Your data has to land in one of those general ledgers, and increasingly the ERP would rather own the payment leg than hand it to you.

Before you buy: what running it by hand actually costs

Most banks today run a DDA per fund, a collateral spreadsheet maintained by one person, and a scramble every time the state report is due. That's genuinely adequate for two or three small districts, one state, no active bond issues.

FAQ

Bottom line

Public funds reward banks that treat the reporting as the product. The deposit is won on rate and lost on a missed collateral filing, an unanswerable GASB question, a spend-down percentage nobody can produce, or a finance director's ERP that still doesn't talk to the bank.

If the book has fund depth and live bond issues, AP, and construction draws all have to leave from the same ledger, that's Hudson's territory. ZSuite has published municipal results, Infinant names the vertical and has direct Fed rails. Agiletics if you're already on Jack Henry.
