The short version

  • Each has a real cost: BlackLine it sits on top of the ERP rather than replacing anything, so it is an additional annual platform cost against a general ledger you are already paying for, and the return has to come from reduced close effort and audit findings rather than from retiring another system.; Modern Treasury you must already have or be able to obtain your own bank accounts with the right connectivity, so early stage companies without a banking relationship cannot use it and are pushed towards a sponsor bank model instead.
  • They diverge on capability: BlackLine covers Account reconciliation, Modern Treasury covers Multi-rail payment initiation.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

BlackLine

  • It sits on top of the ERP rather than replacing anything, so it is an additional annual platform cost against a general ledger you are already paying for, and the return has to come from reduced close effort and audit findings rather than from retiring another system.
  • The capability is split across separately licensed modules, so a reconciliation deployment that later needs journal entry, transaction matching and intercompany turns into three more commercial conversations rather than a configuration change.
  • Implementation runs for months and is normally partner led, because the value depends on how the account inventory, risk ratings, matching rules and ERP data feeds are configured, and a rushed configuration produces a system that certifies bad reconciliations on schedule.
  • The ERP data feeds have to be built and then maintained, so a chart of accounts change, an entity addition or an ERP upgrade turns into remediation work in BlackLine as well, and a broken feed stops the close rather than degrading it.
  • Licensing has a per user element and the close involves preparers, reviewers, controllers and auditors, so a finance function with many occasional reviewers pays for seats belonging to people who touch the system for a few days each month.

Modern Treasury

  • You must already have or be able to obtain your own bank accounts with the right connectivity, so early stage companies without a banking relationship cannot use it and are pushed towards a sponsor bank model instead.
  • Pricing rests on an annual minimum commitment, and companies that miss their volume forecast pay the minimum regardless, which makes the headline per-transaction rate close to irrelevant in year one.
  • Supported bank connectivity is a finite list, so if your bank is not on it you are either waiting for an integration or changing banks, which is a far larger project than adopting the software.
  • It is software over banking, not banking, so it does not solve card issuing, deposit accounts or the licensing questions that a company embedding financial products still has to answer elsewhere.
  • The ledger is genuinely good but adopting it properly means making it the source of truth for balances in your product, which is a significant application change rather than a payments integration and is where implementations run long.

Answered from the vendors’ own pages

BlackLine: Does BlackLine replace our ERP or general ledger?

No. It reads from the ledger and writes approved journals back. You keep the ERP and pay for BlackLine on top of it.

Modern Treasury: Is Modern Treasury a bank or a banking as a service provider?

Neither. You hold your own bank accounts and it is software over them. That avoids sponsor bank concentration risk but means you need the bank relationship yourself.

BlackLine: At what size does it make sense?

The case is usually driven by control requirements and entity count rather than revenue. Companies under a control regime like Sarbanes Oxley, or groups with many entities and a long close, get the return. A single entity business with a short close will not.

Modern Treasury: What does it cost?

Not published. A platform access fee plus usage fees across rails, on an annual term with a single minimum commitment. Negotiate the minimum, not the per-transaction rate.

BlackLine: How long does implementation take?

Months rather than weeks for the first module, longer for multi entity rollouts across several modules. The elapsed time is dominated by agreeing the account inventory and building the data feeds, not by installing software.

Modern Treasury: Which rails are supported?

ACH, wires, RTP, FedNow, push to card, cheques and stablecoin payments, subject to what your bank supports.

BlackLine: Will it shorten our close on its own?

No. It makes the close visible and controlled, which is what exposes where the time goes. Shortening it still requires changing the underlying processes, and companies that skip that step get better documentation of the same slow close.

Modern Treasury: Do we still need our own compliance programme?

Yes. KYB, KYC and transaction monitoring are included in the platform, but you are the one holding the accounts and the regulatory obligation sits with you and your bank.

BlackLine: Can our auditors use it directly?

Yes, giving auditors read access to sample reconciliations and approvals is a common deployment pattern and one of the clearer sources of saved effort during the audit.

BlackLine: What happens if our chart of accounts changes?

The account inventory, risk ratings and feed mappings need updating to match. Treat any significant ERP or chart of accounts change as a BlackLine work package in the same project plan.
