The verdict in three sentences
Connecting an app to SAP is budgeted in 2026 at 30,000 to 120,000 EUR, a spread that is not arbitrary: it comes from the number of IDocs/BAPIs, the choice of middleware layer vs point-to-point, and the number of environments to deliver. Plan for 8 to 16 weeks and 18%/year maintenance. An SAP quote reads per flow: that is the only honest way to compare two proposals.
Why quotes range from 30,000 to 120,000 EUR
An integrator does not price SAP as a flat fee but per flow. Cost per flow depends on the object type (IDoc, BAPI, OData), data transformation and error handling.
| Line | Detail | Indicative 2026 cost (EUR) |
|---|---|---|
| Simple flow (1 IDoc) | Read or write, little mapping | 4,000 - 8,000 |
| Complex flow (BAPI + transform) | Business rules, validations | 8,000 - 18,000 |
| Middleware layer (setup) | ESB / iPaaS, orchestration | 12,000 - 30,000 |
| Dev/staging/prod environments | 3 environments + CI | 6,000 - 15,000 |
| Interface acceptance testing | Test sets, sign-off records | 5,000 - 12,000 |
| Reversibility / documentation | Knowledge transfer | 3,000 - 8,000 |
A 30,000 EUR project = 3-4 simple point-to-point flows; a 120,000 EUR project = 8-10 complex flows on middleware, three environments and formal acceptance. These are not the same deliverables.
Middleware or point-to-point: the structural call
Point-to-point is cheaper upfront but becomes unmanageable as flows multiply. Middleware costs more to set up but absorbs growth.
| Criterion | Point-to-point | Middleware layer (ESB) |
|---|---|---|
| Upfront cost | 30,000 - 60,000 EUR | 60,000 - 120,000 EUR |
| Timeline | 8 - 12 weeks | 12 - 16 weeks |
| Adding a later flow | Costly (rewiring) | Low (reuse) |
| Monitoring | Fragmented | Centralized |
| SLA penalties | Hard to enforce | Framed and measurable |
| Reversibility | Low | Documented |
| Tipping point | < 4 flows | > 5 flows |
On SLAs, a serious contract sets availability (e.g. 99.5%), a recovery time and penalties (often 2 to 5% of the monthly fee per major incident). Also require a reversibility clause: the right to recover code, mappings and documentation.

Mini case study
Thomas, IT director of a 900-employee industrial mid-cap in Berlin, must connect a new production management app to SAP. He gets two quotes: 42,000 EUR point-to-point (4 flows) and 95,000 EUR with middleware (7 flows, 3 environments, formal acceptance, 99.5% SLA). Knowing he plans 4 more flows within 18 months, point-to-point would cost ~35,000 EUR in extra rewiring. Middleware, 53,000 EUR more upfront, becomes the rational choice: adding future flows at 3,000-5,000 EUR each instead of 8,000-12,000 EUR. Maintenance at 18% = 17,100 EUR/year.
FAQ
Why such a spread between quotes? Because they do not cover the same scope: number of flows, architecture (point-to-point vs middleware), number of environments and testing depth. Always ask for per-flow pricing.
What are IDocs and BAPIs? They are SAP's standard exchange mechanisms. An IDoc carries a document (order, invoice), a BAPI calls a business function. Their number largely sets the price.
How long for an SAP project? From 8 weeks (point-to-point, few flows) to 16 weeks (middleware, formal acceptance, three environments).
Which SLA penalties should I require? A quantified availability (99.5% or more), a recovery time, and penalties of 2 to 5% of the monthly fee per major incident. Without a written SLA, there is no recourse.
Does reversibility matter? Essential. Require handover of source code, mappings and documentation so you are not locked to the integrator.
