What to do with this
The estimated 5-year TCO uses public list prices. The real project price always comes from a partner quote. Email yourself the breakdown, or book 30 minutes to walk through next steps.
Every number, with formula and source
No black box. List prices, multipliers and assumptions are all spelled out. When you change a default in the calculator above, the math updates live.
1. SAP Business One cloud
5-yr licence = €/user/mo × users × 60. Default midpoint of the published €47–€91 band: €69.
SAP B1 cloud is sold via the partner channel, mostly within the €47–€91/user/mo band. The calculator defaults to the €69 midpoint but accepts your partner quote. If you choose on-prem (perpetual licence), we add 18% of Y1 implementation as annual maintenance for years 2–5; cloud subscriptions already include maintenance.
Implementation band of €40k–€150k for a 50-user mid-market project is the published industry research figure; overwrite with your partner quote when you have one.
2. Oracle NetSuite
5-yr = base $999×60 + full users × $/user × 60 + self-service users × $/user × 60 + implementation. Cloud subscription includes maintenance.
NetSuite is the only vendor with a separate platform fee: $999/month entry. User licensing is two-tier — full-access users at $99–$199/mo (default $149) and self-service / employee-only users at $10–$25/mo (default $17). Many companies put warehouse, field or seasonal staff on self-service, which the calculator models as a separate line.
Implementation industry band $50k–$200k for a 50-user mid-market project; overwrite with your partner quote.
3. Microsoft Dynamics 365
5-yr = app × $/user × 60 + (premium connectors × $40 × users × 60) + (Power Platform env × $100 × 60) + implementation.
Dynamics 365 list prices are app-level: Sales Professional $65, Sales Enterprise $105, Finance $210 per user per month. Some add-on apps have cheaper Attach licences when a base app is already in place, but full-stack modeling is the safer default. Premium third-party connectors add $40/user/month. Power Platform non-prod environments are $100/month each — many companies run two or three (dev / UAT / staging).
Implementation industry band $50k–$200k for a 50-user mid-market project; your partner quote replaces this.
4. AppForge custom ERP / CRM
5-yr = Y1 build × industry factor × timeline factor + 5 × annual maintenance + (Hungarian NAV line, optional).
Custom bands come from our public pricing.md: CRM 12–30 M HUF Y1 (default midpoint 21 M HUF) + 0.5–1.5 M HUF/yr maintenance; ERP 15–35 M HUF Y1 (default midpoint 25 M HUF) + 2.5–6 M HUF/yr maintenance. Industry factor (manufacturing 1.15, retail 1.0, services 0.95, logistics 1.10) reflects recurring delivery experience — manufacturing carries more MRP and integration scope.
Timeline factor: aggressive (3–4 mo) 1.20×, standard (6–9 mo) 1.0×, careful (12 mo) 0.95×. Aggressive covers parallel-team and overtime rates.

5. FX assumptions
HUF / EUR ≈ 390, HUF / USD ≈ 360. Conservative, rounded snapshot for May 2026. The final TCO contract should pin the exchange rate explicitly.
Most SaaS contracts are billed by the vendor in USD or EUR but invoiced in HUF by a Hungarian Kft partner. Over 5 years that produces 3–8% drift — we recommend a 5% buffer on top of the modeled TCO. The calculator uses one fixed rate so the output is directly comparable across vendors.

6. What the TCO does not include
Training, change management, data migration, integration partner hours, contingency reserve (5–8%), baseline infrastructure (VPN, SSO, monitoring).
The calculator deliberately answers one clean question: what does the vendor cost? Total project budget is typically 5–15% above TCO. We walk through the missing lines and your specific number set on a 30-minute scoping call.
What the result means
If custom is cheapest
Common when standard SaaS modules are largely unused, or when a local jurisdiction requirement would push SaaS into deep customization. Next step: 30-minute scoping call covering business processes, module list and a real project quote.
If a SaaS vendor is cheapest
The SaaS advantage is real when your processes are standard and the industry best practice is acceptable. AppForge can still help with integrations, custom reports, NAV connections or process automation in fixed-price 4–8 week packages.
Within 10–20%
The most common outcome at 50–250 users. Decision becomes strategic, not financial: how unique are your processes, how important is vendor-independent data ownership, how fast must you go live. We score these on a 30-minute scoping call.
If TCO climbs above ~$500k
Enterprise scale. SAP S/4HANA Cloud, Oracle Fusion Cloud ERP or large Dynamics 365 footprints become the right comparison set, and they are not list-priced. Email or call us — at this size more factors apply (consolidation, multi-entity, multi-currency).
