CAS Software Alternatives: Best CRM & CPQ Replacements in 2026
Not the CAS You're Thinking Of
If you searched "CAS software alternatives" expecting math tools, wrong article. CAS Software AG is a German CRM and CPQ vendor founded in 1986 in Karlsruhe - not a computer algebra system. Their two flagship products, CAS genesisWorld (CRM) and CAS Merlin CPQ, are widely used by SMEs in German-speaking markets. This article covers the best replacements for both.
Our Picks at a Glance
| Need | Pick | Why |
|---|---|---|
| Scaling EU teams | Pipedrive (EUR14/user/mo) | Clean UX, Frankfurt hosting, transparent pricing |
| Free CRM to start | HubSpot CRM (free) | Massive ecosystem, paid plans from ~EUR41/month |
| Clean data before migrating | Prospeo (free tier) | 98% email accuracy, 50+ data points per contact |
| CPQ simplicity | PandaDoc ($19/user/mo) | Quotes + proposals + e-sign in one tool |
Why Teams Leave CAS Software AG
CAS genesisWorld earns praise for flexibility and strong project management modules. But the cracks show when teams try to scale or modernize. With just 4 G2 reviews and 2 on Capterra, the user community is remarkably small - which signals limited peer validation outside DACH markets.
The JavaScript shift in newer versions is a common complaint. Starting with X9, customizing dynamic fields in Smart Design requires JavaScript knowledge, a frustration flagged on G2 by users who loved the old no-code approach. Those same reviews call out the collaborative portal as underdeveloped.
On the CPQ side, CAS Merlin CPQ doesn't publish pricing publicly - it's "contact vendor" on Capterra. That's a problem for teams trying to budget. And because CAS relies on a partner ecosystem for implementation and interfaces, support quality varies a lot by country.
Here's the thing: CAS genesisWorld is a perfectly fine CRM if your team is happy with the current setup and your requirements aren't changing fast. The moment you need a more modern stack, faster rollout, or broader ecosystem coverage, you'll feel the friction.
Migrating from CAS genesisWorld means moving thousands of contacts - and stale data kills your new CRM from day one. Prospeo enriches your entire contact list with 50+ data points per record at a 92% match rate, so your new pipeline starts clean.
Enrich your CRM export before you migrate. 98% email accuracy, $0.01 per lead.
Best CRM Alternatives to CAS genesisWorld
CAS genesisWorld starts at EUR17.9/month with a 3.5/5 G2 rating. For European SMEs, the replacement needs to check three boxes above all else: GDPR compliance, EU data residency, and multi-language/multi-currency support.
Pipedrive
Use this if you want a CRM your reps will actually adopt. Pricing runs EUR14-99/user/month, published publicly. EU customers get AWS Frankfurt hosting, and no-code automation covers most workflow needs without a developer.
Skip this if you need deep marketing automation or a built-in helpdesk. Pipedrive is a sales CRM and nothing else - it doesn't try to be your marketing platform, your support desk, or your content management system. For teams under 100 reps who want to stop fighting their software, it's an obvious pick. We've seen teams go from signed contract to live pipeline in under a week, which is roughly a tenth of the time a typical CAS genesisWorld deployment takes through a partner.

HubSpot CRM
HubSpot's free CRM is genuinely usable - contact management, deal tracking, and basic reporting at zero cost. When you're ready to upgrade, paid plans start around EUR41/month, with higher tiers unlocking more automation, sequences, and forecasting.
The catch is cost at scale. HubSpot's higher tiers get expensive quickly, and the jump between tiers is steep. But as a CAS genesisWorld replacement for growth-stage teams, the ecosystem - marketing, service, CMS all under one roof - is hard to beat. We've recommended it to teams making their first CRM switch, and the onboarding experience is consistently smooth.
If your team relies heavily on outreach sequences, consider pairing your CRM with an SDR tool.
Salesforce Starter Suite
Salesforce enters at EUR25/user/month, scaling to EUR165/user/month at Enterprise. EU data centers are available, including Germany. The platform is massively capable, but complexity and cost scale together. If you don't have a dedicated Salesforce admin or plan to hire one, look elsewhere.
To estimate the real all-in cost, it helps to understand your cost to acquire customer and how tooling changes it.
weclapp
A German ERP+CRM combo at EUR15/user/month with servers in Frankfurt. If you're a German SME that wants CRM, invoicing, and inventory in one tool with guaranteed local hosting, weclapp is purpose-built for you. It won't win design awards, but it checks every compliance box and handles multi-currency natively - something many CRM teams care about once they expand beyond a single country.
CentralStationCRM
Free for 3 users, EUR18/month after that. Servers in Germany. A budget pick for micro-teams that need contact management without the overhead. Don't expect reporting depth or automation. This is a digital Rolodex with a clean interface.
Zoho CRM
Free tier available, paid from ~EUR14/user/month. Broad feature set at aggressive pricing. Zoho is the Swiss Army knife of CRMs: it does everything adequately and nothing spectacularly. If data residency is a hard requirement, confirm your hosting region before committing - it's configurable but not automatic.
CRM Comparison Table
| Tool | Starting Price | EU Hosting | Free Tier | Best For |
|---|---|---|---|---|
| CAS genesisWorld | EUR17.9/mo | Not public | No | DACH SMEs (status quo) |
| Pipedrive | EUR14/user/mo | Yes (Frankfurt) | No | Sales teams wanting fast adoption |
| HubSpot CRM | Free | Yes (EU option) | Yes | Growth-stage teams building a stack |
| Salesforce | EUR25/user/mo | Yes | No | Enterprise with admin resources |
| weclapp | EUR15/user/mo | Yes (Frankfurt) | No | German all-in-one ERP+CRM |
| CentralStationCRM | Free (3 users) | Yes (Germany) | Yes | Micro-teams on a budget |
| Zoho CRM | ~EUR14/user/mo | Configurable | Yes | Cost-conscious generalists |
One warning: hidden costs - implementation, add-ons, integrations - typically inflate CRM spend by 20-40% above sticker price. Budget accordingly.
If you’re trying to forecast pipeline impact during the switch, use these sales pipeline benchmarks as a sanity check.
Best CPQ Alternatives to CAS Merlin CPQ
CAS Merlin CPQ holds a 4.0/5 on Capterra from 3 reviews, and its "contact vendor" pricing makes comparison shopping painful. CPQ tools reduce pricing errors by roughly 45%, so the category is worth investing in. Prioritize deployment speed, integration depth with your CRM, and whether a free trial lets you test before committing.
PandaDoc
At $19/user/month, PandaDoc handles quotes, proposals, and e-signatures in a single tool. It's CPQ-lite: perfect for teams that need fast, professional quoting without enterprise-grade product configuration. Free trial available. If your "configuration" needs amount to picking line items and adjusting quantities, PandaDoc is all you need - and it's the tool we'd recommend to most teams leaving CAS Merlin CPQ.
QuoteWerks
Starting at $15/user/month, QuoteWerks is a dedicated quoting engine with strong ERP and CRM integrations. Best for manufacturing or distribution teams that need granular line-item control. Not flashy, but reliable.
Salesforce CPQ
At $75/user/month, this only makes sense if you're already on Salesforce CRM. Deep ecosystem integration and an enterprise-grade rules engine, but the learning curve and cost are real. For teams that aren't already in the Salesforce orbit, the onboarding alone will eat months.
DealHub
Custom pricing, typically $50-100/user/month for mid-market. Best for complex B2B deal rooms with guided selling workflows. DealHub shines when your sales process involves multiple stakeholders, approval chains, and dynamic pricing rules. Demo required.
If you’re standardizing how reps move deals forward, align CPQ with your sales activities so quoting doesn’t become a bottleneck.
CPQ Comparison Table
| Tool | Starting Price | Free Trial | Best For |
|---|---|---|---|
| CAS Merlin CPQ | ~EUR40-80/user/mo (est.) | Yes | DACH manufacturing |
| PandaDoc | $19/user/mo | Yes | Most teams leaving CAS CPQ |
| QuoteWerks | $15/user/mo | Yes | Line-item quoting in manufacturing |
| Salesforce CPQ | $75/user/mo | Varies | Teams already on Salesforce |
| DealHub | ~$50-100/user/mo | Demo | Complex multi-stakeholder deals |
Clean Your Data Before You Migrate
Your contacts are the first casualty when switching CRMs. CAS genesisWorld exports often include stale emails, outdated job titles, missing phone numbers, and duplicates. Import that mess into Pipedrive or HubSpot and you're starting on a broken foundation.
New CRM, same bad data? That's the #1 migration mistake. Prospeo's 7-day data refresh cycle means every email and phone number you import is current - not 6 weeks stale like competitors. 15,000+ companies trust it to keep their pipelines accurate.
Start your new CRM with verified contacts, not bounced emails.
If you’re evaluating vendors for this step, compare data enrichment services and prioritize match rate + refresh cadence.
How to Choose the Right Replacement
Before you sign anything, run through this checklist:
- EU data residency. For European SMEs, this isn't optional. Confirm where your data physically lives - "GDPR compliant" and "hosted in the EU" aren't the same thing.
- Localization. Multi-language interfaces, local currencies, and region-specific sales workflows matter more than most vendors admit. Test with your actual team, not a demo account set to English.
- Integration ecosystem. Does the new CRM connect to your email, ERP, and marketing tools without custom middleware?
- Total cost, not sticker price. Add 20-40% to the listed per-user price for implementation, training, and add-ons. That's the real number.
- Migration path. Can you export cleanly from CAS genesisWorld? Most CRMs accept CSV imports, but field mapping takes work. Enrich your contacts before importing so reps aren't chasing dead leads from day one.
If you’re building a repeatable outbound motion after the switch, these sales prospecting techniques help keep pipeline consistent.
Let's be honest about the decision itself: choosing among CAS software alternatives comes down to where your team is headed, not where it's been. Pick the tool that fits your next stage of growth, not the one that mirrors what you already have.
