The short version

  • Each has a real cost: SAP S/4HANA implementation and integration costs routinely run to several times the software cost, and the subscription clock typically starts long before go live, so the first contract year buys much less usable production time than the headline suggests.; Unanet no pricing is published for any Unanet product; every line is quoted per user per month with separate implementation fees, so a small contractor cannot budget the first year without a full sales cycle.
  • They diverge on capability: SAP S/4HANA covers HANA in-memory database, Unanet covers DCAA-oriented timekeeping.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

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

SAP S/4HANA

  • Implementation and integration costs routinely run to several times the software cost, and the subscription clock typically starts long before go live, so the first contract year buys much less usable production time than the headline suggests.
  • Custom ABAP from an ECC installation must be assessed against the simplification list and either retired or rebuilt, and this remediation is normally the largest and most underestimated line in a brownfield conversion.
  • The public cloud edition constrains modification by design, so organisations that depend on non-standard processes are pushed either to change the process or to pay for the private edition, and that decision is often made after the contract is signed.
  • SAP intends extensions to live on the separately licensed Business Technology Platform, so the extensibility model that makes upgrades safe also adds a second subscription and a second set of skills to the total cost.
  • Exit is effectively impossible at reasonable cost, because the data model, the accumulated configuration and the trained staff around a large installation represent a switching cost that outweighs any competing vendor's discount, so the decision binds for a decade or more.

Unanet

  • No pricing is published for any Unanet product; every line is quoted per user per month with separate implementation fees, so a small contractor cannot budget the first year without a full sales cycle.
  • Implementation is a project rather than a signup, involving chart of accounts design, indirect pool structure and data migration, and third parties report implementation fees reaching five figures for mid-sized deployments, an amount easily missed when comparing per-user rates.
  • The interface is dated compared with modern SaaS finance products, which raises training time for staff who only touch it to enter a timesheet and increases the support burden on the finance team.
  • ERP and CRM are separate products with separate contracts, so a firm that wants pipeline, backlog and actuals in one place pays twice and still deals with an integration boundary between them.
  • Its value is concentrated in United States federal and state contracting compliance, so a firm that does no public-sector work is paying for indirect rate machinery and DCAA audit behaviour it will never use, and a non-US firm gets almost nothing from the product’s main differentiator.

Answered from the vendors’ own pages

SAP S/4HANA: What is the actual deadline for leaving ECC?

SAP has set mainstream maintenance for the older Business Suite to end in 2027, with paid extended maintenance available for a further period to 2030. Confirm the current dates and terms with SAP directly, because the commercial detail has been adjusted more than once and it determines your negotiating window.

Unanet: What does Unanet cost?

Nothing is published. Pricing is per user per month and quoted, with implementation fees charged separately on top of the subscription.

SAP S/4HANA: Greenfield or brownfield?

Brownfield carries your existing configuration and custom code forward, which is faster to start and slower to finish because everything must be remediated. Greenfield rebuilds on standard processes, which costs more in change management and leaves a cleaner system. The right answer depends mostly on how much of your existing configuration you would defend to a board.

Unanet: Does Unanet make you DCAA compliant?

No software does. Unanet provides the timekeeping controls, audit trail and indirect rate accounting that an adequacy review looks for; the policies and their enforcement are still yours.

SAP S/4HANA: Is the public cloud edition cheaper?

To run, generally yes. Whether it is cheaper overall depends on whether your processes fit within its extensibility limits. If they do not, the savings evaporate into workarounds or into a move to the private edition.

Unanet: Is Unanet CRM included with the ERP?

No. Unanet CRM, built on the acquired Cosential platform, is a separate product with its own contract.

SAP S/4HANA: How should I approach pricing negotiation?

Treat licence, infrastructure, BTP, the integrator and the internal backfill as one number and negotiate against it. Also settle indirect and digital access terms explicitly in writing, since usage from connected systems has been a recurring source of unbudgeted cost.

Unanet: How does it compare with Deltek?

Unanet typically targets smaller contractors than Deltek Costpoint and is quicker to implement, but has less depth for very large multi-segment organisations.
