The verdict in three sentences
A custom CPQ (Configure, Price, Quote) turns the options of a complex product into an automatic priced quote and bill of materials, with no calculation error. Budget 40,000 to 100,000 EUR (excl. VAT) over 14 to 24 weeks, with most of the budget going to modelling your business rules. The return: quoting time divided by five and a near-zero pricing error rate.
SaaS CPQ vs custom: which for a complex manufacturer?
SaaS CPQs (Salesforce CPQ, Tacton) shine on standardised catalogues but stumble on deep industrial rules (technical constraints, dynamic BOMs). 2026 orders of magnitude.
| Criterion | SaaS CPQ | Custom CPQ |
|---|---|---|
| Setup | 30,000 - 120,000 EUR | 40,000 - 100,000 EUR |
| Subscription | 100 - 250 EUR/user/mo | 0 EUR (hosting) |
| Complex technical rules | Limited / add-ons | Unlimited |
| BOM generation | Often optional | Native |
| ERP/production link | Paid connectors | Custom |
| Code ownership | No | Yes |
For 20 sales reps at 150 EUR/month, SaaS costs 36,000 EUR/year, i.e. 180,000 EUR over 5 years: once the rules are truly domain-specific, custom prevails.
The real cost: modelling business rules
A CPQ's value lies in the depth of its rules (compatibilities, constraints, pricing, manufacturing time). This is the central budget item.
| Rule type | Example | Effort (days) | Cost (2026) |
|---|---|---|---|
| Option compatibility | Option A excludes B | 8 - 14 | 6,000 - 11,000 EUR |
| Parametric pricing | Price = f(dimensions, material) | 10 - 16 | 7,500 - 13,000 EUR |
| Dynamic BOM | BOM generated by config | 12 - 20 | 9,000 - 15,000 EUR |
| Technical constraints | Physical/standard limits | 8 - 14 | 6,000 - 11,000 EUR |
| PDF quote + terms | Auto sales document | 5 - 9 | 4,000 - 7,000 EUR |
Modelling often represents 30,000 to 55,000 EUR: this is where configurator quality is decided.

Mini case study
Thomas, sales director of an industrial joinery manufacturer in Strasbourg, receives 160 quote requests/month. Each takes on average 3 h of an account manager's time (option capture, calculation, BOM), i.e. 480 h/month. The CPQ cuts this to 35 minutes per quote, freeing about 387 h/month, the equivalent of 2.5 FTE redeployed to sales follow-up. At a loaded cost of 38 EUR/h, that is 14,700 EUR/month of capacity recovered. His configurator costs 75,000 EUR plus 12,000 EUR/year: payback in about 6 months, before counting the +20% conversion.
FAQ
Can the configurator be customer-facing online? Yes: you can expose a front-end version so the customer configures themselves and gets an instant quote, while keeping a fuller internal version for complex cases.
Does it generate the production BOM? Yes, a major benefit of custom: each configuration produces its BOM and can feed the ERP or MES, eliminating double entry.
How long for a first useful configurator? Expect 14 to 20 weeks for a priority range. You model the best-selling product family first, then extend.
What if our rules change? Rules are editable; plan maintenance of 12 to 18% of the build per year to incorporate new options, materials and price grids.
Can the CPQ connect to our ERP? Yes, via API: the validated quote becomes an order and BOM in the ERP, making the whole flow reliable through to production.
