SAP Certified Integration Vs Simple SAP Connector – Which One Do You Need?
Mateusz
This guide will help vendors decide if they need the official SAP badge (for sales) or just a Standard SAP API (for functionality).
There is a question that comes up in almost every conversation we have with SaaS vendors trying to break into the enterprise market: do we actually need the SAP certification badge, or can we just build a connector and get on with it?
It is a fair question, and the honest answer is: it depends. Which is not a cop-out. It genuinely depends on what you are building, who you are selling to, and how serious you are about going after large enterprise accounts.
What we have noticed, working with vendors at different stages of this journey, is that most teams either over-invest in certification before the business is ready for it, or they under-invest and find themselves locked out of procurement processes. Neither situation is particularly fun to be in.
So this guide is an attempt to lay out the actual decision clearly. No push in either direction. Just analyse the factors that tend to matter, and a framework you can use to work out where you sit.
First, What Are We Actually Talking About?
Before making any decision, let me be precise about what “SAP integration” even means, because the term gets used loosely in a way that conflates two very different things. Simple SAP Connectivity means your application communicates with an SAP system through standard interfaces. This could be REST APIs, OData services, BAPIs (Business Application Programming Interfaces), IDocs, or going through SAP Business Technology Platform (BTP) services. You are connecting to SAP the way any developer connects to an external system. There is no third-party validation involved. You built it, you maintain it, and it works until something changes on either end.
While SAP Certified Integration means your connector has gone through SAP’s Integration and Certification Center (SAP ICC) validation process. SAP’s testing team runs your integration through a defined ICC test catalogue (there is a dedicated catalogue for certified connectors – not necessarily build partners) covering functionality, security, error handling, and compatibility against a specific SAP product version. The certification is tied to a specific product version and requires renewal as SAP releases new versions.

And if you want to get listed on the SAP store, it requires ARC + SAP Build Partnership.
The SAP Cloud Connector: A Specific Tool Worth Understanding Before You Build Anything
If you are selling to companies running SAP on-premise or S/4HANA cloud, you will encounter the SAP Cloud Connector.
The SAP Cloud Connector is a lightweight agent installed in the customer’s network. It creates an encrypted tunnel between the customer’s internal SAP system and SAP BTP in the cloud, without requiring the customer to open inbound firewall ports. Your SaaS application, running in the cloud, talks to SAP BTP, which routes requests through that tunnel to the on-premise system.
This matters for your integration architecture decision. If your target customers are running on-premise SAP systems, you need to build on BTP. The SAP Cloud Connector is a technical layer that sits in the customer’s on-premise network and connects exclusively to BTP. It is not something you architect around; it is something that works automatically once your application is on the platform. Your SaaS application connects to BTP, BTP routes through the Cloud Connector tunnel to the on-premise SAP system, and the customer’s IT team never has to open inbound firewall ports.
Two Technical Paths, Two Very Different Outcomes
For the CTO, the choice of integration method involves a deep dive into the underlying protocols and the associated maintenance burden. Modern SAP environments, particularly S/4HANA Cloud, offer a variety of connectivity options, each with unique performance and stability characteristics.
Path A: The Custom/Independent API Connector
This approach makes sense when you need to support highly specific business logic, legacy SAP versions like ECC 6.0, or integration scenarios where your team has strong existing expertise in a particular connectivity stack, and the use case does not justify the overhead of a full BTP-based architecture. BTP can act as middleware across all of these scenarios; the choice to build independently is a design and resourcing decision, not a technical limitation.
The catch is that independent connectors are notoriously brittle. Because they tend to break during SAP’s quarterly update cycles and may require constant engineering attention to restore functionality.
Building a custom connector from scratch is also resource-intensive. You need people who can bridge web protocols and deep SAP business logic: OData, IDocs, BAPIs, ABAP. The Initial SAP Connector development cost runs between €60,000 and €150,000 (depending on complexity, endpoints, and custom logic), with ongoing maintenance of up to €5,000 per month. However, a standard Pre-built connector costs much less than a custom one.

Path B: The SAP Certified Integration (ICC-Validated)
The certified route means building within the SAP ICC framework, typically leveraging SAP Integration Suite or SAP BTP. Certified connectors use officially released and supported APIs that SAP guarantees remain stable through system upgrades. That upgrade resilience is a primary selling point for enterprise IT departments that are worried that third-party integrations will block their migration or disrupt critical financial close processes.
The certification process is rigorous. It involves scenario-based testing that proves your SaaS can handle real-world production workloads, with proper error handling, retry logic, and security protocols like OAuth 2.0 or SAML. The real cost involved in direct certification is the engineering time required to meet ICC’s Clean Core standards.
| Metric | Independent Connector | Certified Integration |
|---|---|---|
| Initial Dev Cost | €60,000 – €150,000+ | €10,000 – €50,000 (if prebuilt) |
| Talent Requirement | High (SAP Experts at €150/hr) | Vendor-managed or Middleware-led |
| Time to Market | 3 – 6 Months | 2 – 4 Weeks (if using adapters) |
| Maintenance Burden | High (Internal Team) | Low (Vendor/Update Guaranteed) |
| Upgrade Resilience | Low (Often Breaks) | High (Guaranteed Stability) |
The Business Case for Certified Integration
For SaaS executives, certification is a sales efficiency investment as much as a technical one.
In the enterprise segment, the “SAP Certified” logo acts as a binary filter during procurement. CIOs and procurement officers at Global 2000 companies recognise that an uncertified product introduces governance risks, often requiring months of discovery workshops and technical audits before they will even shortlist you.
On sales cycles: Carrying a certified SAP connector on your product sheet can cut enterprise sales cycles by 40% to 60%. When the “fear, uncertainty, and doubt” around integration stability is removed, your sales team stops getting bogged down in technical objections and can focus on business value.
On retention: Integration depth is one of the strongest retention drivers in the enterprise SaaS market. Tools that become part of the daily SAP workflow, automating invoice postings in S/4HANA Finance or syncing employee data in SuccessFactors, become part of the enterprise’s operational DNA. The cost of switching away from a deeply embedded tool is prohibitive, which means predictable, long-term revenue for you.
On total cost of ownership: Custom-built integrations create a web of complexity that grows increasingly difficult and expensive to maintain as the system scales. Technical debt in the SAP environment is essentially the implied cost of future rework. Adhering to Clean Core standards early means avoiding the massive refactoring projects that plague legacy ISVs.

What Is the Cost of SAP Certification
SAP certification through the ICC is not free. There are direct fees for the certification test, which vary depending on the product type and how many test scenarios are in scope. Beyond those fees, you need to budget for:
- Developer time to build to SAP’s technical specifications
- Time to set up and manage the test environment SAP requires
- Ongoing recertification costs when SAP releases a new product version
Certified integrations should be built on stable APIs. SAP promises not to break them in newer versions. The part most teams miss is that sometimes you need to recertify if the certification expires, OR if the integration needs to be updated and a new version is to be released.
When Simple Connectivity Is Enough
You can get away with an uncertified integration when your customer profile is mid-market or smaller enterprise where procurement processes are less rigorous, your integration is read-only or handles non-critical data flows, you are in early stages and validating product-market fit with a handful of design partners, the integration is customer-managed (their IT team owns it, not yours), and no one in the sales process has asked for certification.
In these situations, spending €15,000 to €40,000 and three to six months on SAP certification before you have ten paying customers is premature optimisation, not strategic investment.
When SAP Certification Becomes the Right Call
The calculus changes fast in a few specific scenarios.
Enterprise procurement requires it. Large enterprise procurement teams, particularly in DACH, treat SAP certification as a baseline. It shows up on vendor qualification checklists. Without it, you often do not make the shortlist, regardless of how strong your product is.
You want to sell through the SAP Store. The SAP Store is a meaningful distribution channel for customers who have SAP as a preferred vendor. To list there, certification is required. If SAP is part of your channel strategy, certification is not optional.
Your integration handles financial or compliance-critical data. If your connector is touching financial postings, procurement workflows, HR data, or anything feeding into auditable business processes, enterprise customers will want evidence that the integration has been independently validated.
You are competing against certified solutions. When a competitor in your space carries the badge, and you do not, the objection surfaces at the worst possible moment, usually right before contract signing.
You are building a product, not a project. If you are selling a repeatable SaaS product deployed across many customers, you are building an asset. Certifying that asset makes it defensible, marketable, and commercially differentiated.
A Quick Decision Matrix
Use this as a starting point. No single row makes the decision for you, but if you are checking four or more boxes in the “Get Certified” column, the business case is probably already there.
| Criteria | Simple Connectivity | Get SAP Certified |
|---|---|---|
| Target customer size | Mid-market, SMB, or sectors where SAP penetration is low | Large enterprise (5,000+ employees). Global 2000 buyers in manufacturing, logistics, and utilities, SAP penetration is close to 100% |
| Sales stage | Pre-PMF, early design partners, fewer than ten enterprise customers | Scaling into enterprise accounts, certification shortens sales cycles, not lengthens them |
| SAP Store strategy | Not part of your current distribution plan | Ecosystem-led growth is part of your strategy. SAP Store access and co-marketing at Sapphire or TechEd are strictly gated by certification |
| Data sensitivity | Operational, non-critical data flows | Financial postings, HR, procurement, and compliance workflows. Lack of certification can be a binary deal-killer |
| Procurement process | No formal vendor qualification required | RFPs, IT security reviews, and approved vendor lists, without the badge, you often do not make the shortlist |
| Technical capacity | SAP expertise in-house or not yet needed | If no SAP background internally, partnering with an authorised SAP firm or using prebuilt certified connectors is more cost-effective than building from scratch |
| Product stability | Still iterating on core architecture | PMF established, and integration requirements are consistent, certifying a moving target wastes capital |
| Integration ownership | Customer’s IT team owns and manages it | Your product is the integration, deployed across many customers |
| Deal size | Under $50K ACV | $100K+ ACV, multi-year contracts |
| Timeline pressure | Need to ship fast, validate first | Enterprise deals in the pipeline now require it |
Run through these questions before you commit either way:
- Are your target enterprise customers requiring certification during procurement? If yes, get certified.
- Are you planning to list on the SAP Store as part of your distribution strategy? If yes, you need it.
- Are you handling financial, compliance, or audit-critical data flows? If yes, you should strongly consider it.
- Are you still validating product-market fit with fewer than ten enterprise customers? If yes, hold off and invest in a well-built connector first.
- Is your integration one-directional, read-only, or handling non-sensitive operational data? If yes, simple connectivity may serve you well for longer than you expect.
The Bottom Line
The mistake most SaaS teams make is treating certification as an engineering question. It is a go-to-market question. If you are targeting Global 2000 buyers in regulated industries, going after DACH enterprise accounts, or building a repeatable product that needs to scale across many enterprise customers, certification pays for itself faster than most teams expect.
If you are still validating product-market fit with early design partners, a well-architected connector gets you moving without unnecessary overhead.
Get the business question right first. The technical path follows from there.
Most SAP consultancies will either push you toward full certification immediately (because it is a bigger project) or tell you a basic connector is fine (because it is faster to deliver). Neither answer serves you well without understanding your actual situation.
At AvoTechs, we do both. We build integration connectors designed to work correctly from day one against SAP’s technical standards, and we support the full SAP certification process for clients who need it. We have been through the SAP ICC process (See Velocitor Solutions Case Study). We know what actually gets tested, what gets flagged, and where projects typically stall.
We’ll guide you on when to hold off on SAP certification until the business case justifies it.
If you are a SaaS company deciding to pursue SAP certification or you just need a reliable, well-architected connector, AvoTechs can help.
