Both are external IT firms you pay monthly, and German-speaking buyers search for both as a Dienstleister, so they land in the same shortlist constantly. They sell different things. One is measured on whether existing systems stay up. The other is measured on whether something that did not exist now ships. This page separates them so you brief the right category. Illustrative buyer scenario, not a customer quotation If the deliverable is software that did not exist before, you are buying delivery. If the deliverable is keeping existing systems running, you are buying availability. No vendor is excellent at both. TL;DR Building new software versus keeping existing IT running. Two different businesses, two different contracts, and the reason briefs land in the wrong category. // 01 ## Decision snapshot VerdictIf the deliverable is software that did not exist before, hire a software agency on a Werkvertrag. If the deliverable is keeping existing systems running, hire an IT service provider on a service contract with an SLA. Most companies need both, from two different vendors. ### Wavect is best when - A new product, or a custom internal system, that has to exist and reach production - A codebase that needs taking over from a previous provider and moving forward again - Product decisions and senior engineering in the same conversation, before you can hire for either ### The alternative is best when - Networks, workstations, servers, identity, backups and patching kept running - A helpdesk your staff can call, with contractual response times - Vendor licensing, hardware procurement and infrastructure operations under one roof ### Questions to ask before you choose 1. What is the deliverable: something new that ships, or something existing that stays up? 2. Am I buying an obligation of result (Werkvertrag) or an obligation of effort with an availability promise (Dienstvertrag or Rahmenvertrag)? 3. If a vendor offers both, who exactly staffs the software side, and is that team its core business or a side line? 4. Who owns the source code and the intellectual property when the engagement ends? 5. Who operates the software after handover, and is that written down before the build starts? ### Commercial risk to watch - Sending one RFP to both categories produces proposals that cannot be compared: one prices availability per seat, the other prices a scope - Buying a product build from an operations-first vendor usually means hourly billing and a team optimised for stability rather than for reaching product-market fit - Buying managed IT from a product agency means no helpdesk, no 24/7 desk and no operational SLA, which is a real gap if that is what the business needed ### Evidence notes - This is a comparison of two service categories, not of named firms. No specific provider is assessed here. - Wavect does not offer managed IT, helpdesk, network or workstation operations. That statement is a scope boundary, not a criticism of vendors who do. // 02 ## Project fit: not limited to small builds Project size and provider headcount are separate decisions. Wavect’s delivery unit is a named senior core, but that does not limit the work to MVPs or short startup projects. Larger projects are split into phases with separate budgets and acceptance criteria. We also build internal systems and process automations inside a client’s existing repositories, tooling and workflows. A vetted bench supports continuity and scope-specific capacity. A larger provider may still be the better choice when the main requirement is several parallel teams, an incumbent framework agreement or certifications Wavect does not currently hold. // 03 ## How they actually differ Compared on the dimensions that actually differ. Both categories contain excellent firms and weak ones; this is about which category fits which brief. | WAVECT | DIMENSION | ALTERNATIVE | | --- | --- | --- | | Delivery: software that did not exist before, working in production | What you are buying | Availability: existing systems, networks and devices kept running | | Werkvertrag, an obligation of result, or a monthly retainer | Natural contract type | Dienstvertrag or framework agreement, an obligation of effort plus an SLA | | The product shipped and did what the business needed | How success is measured | Uptime, response times and tickets resolved inside the SLA | | Both founders, senior by construction, the people who scoped it | Who is on your project | A named account team plus a shared support pool, sized to the seat count | | You do. It transfers, with no lock-in | Who owns the code and IP | Usually not applicable: the work is operations, not authored software | | Neither. No vendor certifications, no round-the-clock support desk | Certifications and 24/7 desk | Typically both: vendor certifications for what they resell, plus contractual out-of-hours cover | | Fixed-scope build, or weekly billing that is cancellable any week | Typical commercial model | Monthly fee per seat or per device, on a multi-year term | | Anything to do with running IT: we decline it and say so | Where the other one is better | Anything that requires product judgement and a new codebase | // 04 ## The real difference, in practice The two categories share a shelf in the buyer’s mind and almost nothing else. Read any procurement shortlist in the DACH region and you will find a Systemhaus sitting next to a product studio, because both answered a brief that said “we need software people”. The word Dienstleister covers both in German, which is exactly why the shortlist forms. Start from the deliverable, because everything else follows from it. An IT service provider is paid to make sure things that already exist keep working: the network, the laptops, the file server, the cloud tenancy, the identity provider, the backups. Success is measured in uptime and response time. A software agency, also searched for as a software service provider or Softwaredienstleister, is paid to make something that does not exist yet work in production. Success is measured in whether the thing shipped, and whether it did what the business needed. That difference propagates straight into the contract. Managed IT naturally sits on a Dienstvertrag or a framework agreement: an obligation of effort, with an availability promise bolted on. Custom software delivery naturally sits on a Werkvertrag: an obligation of result. Once you notice that, comparing day rates across the two stops making sense, because you are not buying the same kind of promise. A cheaper hourly rate attached to an effort obligation is not cheaper than a higher rate attached to a result obligation. It also propagates into who is in the room. Operations organisations are staffed and rewarded for stability: predictable process, low change rate, clear escalation paths. Product organisations are staffed and rewarded for judgement under uncertainty: deciding what not to build, changing direction when evidence arrives. Both are legitimate engineering cultures. Neither converts easily into the other, which is why a vendor that genuinely does both usually runs them as two separate businesses with two separate hiring bars. So when a firm from either category offers the other as a service line, the question is not whether they are honest. It is who staffs it. Ask how many people work on that line, whether they are the same people who handle the core business, and what they shipped most recently. The answer is usually informative and easy to get. The healthy end state for most companies past a certain size is both, from two different vendors, with a clear handover boundary written down before the build starts. We have worked in exactly that arrangement: on the IKB engagement our work sat inside the utility’s own build, on infrastructure, devices and codecs, with a complete handover after year one. We were never the operator of the surrounding systems and never claimed to be. Where does that leave Wavect? On one side of the line, deliberately. We build and hand over custom software. We do not run IT operations: no helpdesk, no workstation or network management, no 24/7 on-site desk, no operational SLA. If your actual problem is that nobody is keeping the lights on, we are the wrong call and an IT service provider is the right one. If your actual problem is that something needs to exist and reach production, that is our work, and the code transfers to you. // 05 ## When each is the better call // 01 ### When a software agency is the better call - Something has to exist that does not exist yet, and it has to reach production - You inherited a codebase from a previous provider and need it assessed and moved forward - Product decisions and engineering trade-offs need to happen in the same conversation - You want the code and the intellectual property to end up yours // 02 ### When an IT service provider is the better call - The real problem is that networks, devices, servers or identity need someone accountable for uptime - Your staff need a helpdesk to call, with contractual response times - You need vendor licensing, hardware procurement and infrastructure operations handled together - You need out-of-hours or 24/7 cover, which we do not offer Most companies eventually need both. If your brief is really an operations brief, we will tell you that on the first call instead of quoting for it. // 06 ## Relevant Wavect work - [SERVICE Custom Software Development](/services/software-development/) - [SERVICE Software Takeover](/services/software-takeover/) - [CASE STUDY IKB: engineering inside a municipal utility's build](/case-studies/ikb/) - [GUIDE How to choose a software development agency](/software-development-guide/how-to-choose-a-software-agency/) // 07 ## FAQs ### What is the difference between a software agency and an IT service provider? A software agency builds software that did not exist before and is measured on delivery. An IT service provider, Systemhaus or MSP runs and supports your existing IT under an SLA and is measured on availability. The contracts differ for the same reason: an obligation of result versus an obligation of effort. Most companies need both, from two different vendors. ### Is a Softwaredienstleister the same as an IT-Dienstleister? No, and this is where the German vocabulary misleads people. Softwaredienstleister is a synonym for Softwareagentur: a firm you hire to build software. IT-Dienstleister points at the operations business: Systemhaus, managed services, helpdesk. The shared word Dienstleister is why both end up in the same shortlist, and why briefs get sent to the wrong category. ### Can one vendor do both? Some do, and the question to ask is who staffs the smaller of the two lines. Operations and product delivery reward different behaviour and hire to different bars, so a firm that genuinely does both usually runs them as separate businesses. Ask how many people are on the line you care about, whether they also cover the core business, and what they shipped most recently. ### Does Wavect offer managed IT, a helpdesk or 24/7 support? No. We build custom software and hand it over. No helpdesk, no network or workstation management, no round-the-clock desk, no operational SLA. If that is the requirement, hire an IT service provider for it. We are happy to build alongside the provider you already have and hand the running system over cleanly. ### How do I compare quotes from both categories? You cannot compare them directly, and trying to is the most common procurement mistake here. One quote prices availability per seat over a multi-year term; the other prices a defined scope once. Decide which deliverable you are buying first, then shortlist inside that single category and compare like with like.
