The short version

  • Only Constant Contact has a free tier, so it costs nothing to try first.
  • 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.; Constant Contact core plan started at $9.99 per month and Plus plan at $45 per month, both scaling by contact list size rather than a flat rate (Internet Archive capture, 2022)
  • They diverge on capability: BlackLine covers Account reconciliation, Constant Contact covers Email marketing.
  • Prices and features above were last checked on 30 August 2026.

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.

Constant Contact

  • Core plan started at $9.99 per month and Plus plan at $45 per month, both scaling by contact list size rather than a flat rate (Internet Archive capture, 2022)

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.

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.

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.

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.

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.
