The verdict in three sentences
Wiring an LLM (Claude, GPT) onto your inbound emails to pre-draft quotes costs 10,000 to 22,000 EUR to build, then 300-500 EUR/month in API usage. Quote drafting time drops from 40 to 10 minutes, freeing 25 to 45 hours/month and lifting the win rate by around 12 points. With EU hosting and GDPR-compliant processing, the setup is deployable in an SMB without major legal risk.
Build vs usage cost: the 2026 pricing
| Item | 2026 range | Detail |
|---|---|---|
| LLM integration build | 10,000-22,000 EUR | Email parsing, business prompt, PDF generation, human validation |
| API cost (tokens) | 0.003-0.015 EUR/1k tokens | By model and context length |
| Typical monthly usage | 300-500 EUR/month | 400-800 quotes/month |
| EU hosting / GDPR | 40-90 EUR/month | Customer data in Europe |
| Annual maintenance | 10-15% of build | Prompt tuning, evolutions |
The build includes reading the email, extracting needs, building the quote from your catalogue and margin rules, then a human validation before sending. The AI proposes, the sales rep confirms.
Hours gained and commercial impact
| Metric | Before AI | After AI | Gain |
|---|---|---|---|
| Time per quote | 40 min | 10 min | -75% |
| Quotes/month handled | 120 | 200 | +67% |
| Drafting hours/month | 80 h | 33 h | -47 h |
| Average response time | 2 days | 3 hours | -90% |
| Win rate | 22% | 34% | +12 pts |
Response time cut several-fold is often the deciding factor: the first quote received wins a significant share of deals. On 200 quotes/month, +12 points of win rate means 24 extra deals won.
Concrete API cost by volume
| Quotes/month | Estimated tokens | API cost/month | Cost per quote |
|---|---|---|---|
| 200 quotes | ~3M tokens | ~150-300 EUR | 0.75-1.50 EUR |
| 400 quotes | ~6M tokens | ~300-450 EUR | 0.75-1.10 EUR |
| 800 quotes | ~12M tokens | ~450-700 EUR | 0.55-0.90 EUR |
The marginal cost per quote stays below 1.50 EUR, negligible against the 30 minutes of sales time saved (about 17-20 EUR of loaded time).

Mini case study
Julia runs a 25-employee technical services SMB in Berlin, 180 quotes/month. Her team spends 72 hours/month drafting quotes, average lead time 2 days. She invests 16,000 EUR in an LLM integration, 380 EUR/month API usage + hosting.
Monthly gain: 45 hours recovered x 38 EUR = 1,710 EUR, minus 380 EUR = 1,330 EUR net on time alone. Adding +12 points of win rate on 180 quotes (some twenty extra deals won), payback on the build falls to 4-6 months. Over 3 years, saved time alone exceeds 47,000 EUR.
