The verdict in three sentences
A custom AI-assisted quoting engine costs EUR 15,000 to 45,000 net for 6 to 10 weeks of development and cuts the time to draft a quote by a factor of 3. LLM inference stays marginal — roughly EUR 0.01 to 0.03 per quote — compared to the sales-productivity gain. For a Berlin SME producing 30 to 60 quotes a month, payback typically lands under 9 months, with conversion up 8 to 12 %.
What an AI quoting engine actually does
The principle: the AI extracts the requirement (client email, call notes, spec sheet), matches it to your price catalogue and margin rules, then generates a ready-to-send PDF quote. The salesperson reviews and approves instead of typing everything. The technical building blocks vary with the maturity you target.
| Functional block | Role | 2026 complexity |
|---|---|---|
| Requirement extraction (LLM) | Turn an email into quote lines | Medium |
| Price catalogue + margin rules | Consistent, up-to-date pricing | Low to medium |
| Custom PDF generation | Quote in your branding, legal notices | Low |
| CRM / ERP connection | Client history, follow-ups | Medium to high |
| Learning from approved quotes | Refine pricing over time | High |
Most SMEs start with the first three blocks, then add CRM and learning in phase 2.
What it really costs in 2026
The ranges below reflect a vendor day rate of EUR 500 to 700 net in the Berlin region, excluding premium studios. LLM API cost is usage-based and negligible next to the rest.
| Line item | 2026 range (EUR net) | Note |
|---|---|---|
| Scoping + flow mockup | 2,000 – 4,500 | 1 to 2 weeks |
| Engine development (v1) | 10,000 – 28,000 | Extraction + pricing + PDF |
| CRM / ERP integration | 3,000 – 9,000 | Optional in v1 |
| LLM API cost | 0.01 – 0.03 / quote | ~EUR 1.50 for 60 quotes/month |
| Monthly maintenance | 400 – 900 / month | Tune prompts + catalogue |
Realistic entry budget: EUR 15,000 net for a solid connector-free v1, EUR 30,000 to 45,000 net with CRM integration and learning.

Mini case study
Thomas runs an 18-employee carpentry SME in Berlin. His two account managers each spend 7 hours a week on quotes — 14 weekly hours at a loaded cost of EUR 38/h, about EUR 532 per week, or EUR 25,500 a year. With the AI engine, quoting time drops to 2.3 hours per person (factor of 3), freeing ~9.4 hours a week, or EUR 17,800 saved yearly. Add a conversion rate rising from 24 % to 27 % on 50 monthly quotes at a EUR 3,200 average basket: that is ~EUR 57,600 in extra annual revenue. For a EUR 32,000 net investment plus EUR 700/month maintenance, break-even lands in about 6 months.
FAQ
Can the AI get the pricing wrong? Yes, which is why pricing relies on your catalogue and margin rules, not on the model's invention. The salesperson always validates; the observed error rate after tuning stays below 2 % on standard lines.
Do we have to send our prices to a US AI provider? Not necessarily. Sensitive data can stay server-side, sending the LLM only the requirement text, or you can use a Europe-hosted model. GDPR and your confidentiality clauses are respected by design.
How long until it goes live? Expect 6 to 10 weeks for a v1, including 1 to 2 weeks of scoping. A first batch of test quotes runs from week 4 or 5.
What does the LLM API cost each month? For 30 to 60 monthly quotes, the 2026 order of magnitude is EUR 1 to 3/month. The dominant cost stays human maintenance, not inference.
What if our catalogue changes often? Maintenance (EUR 400 to 900/month) exists precisely to keep catalogue, margins and prompts current. A living catalogue is the norm, not the exception.
