The verdict in three sentences
An AI quote generation assistant for a Dublin construction contractor costs EUR 8,000 to 25,000 excl. VAT, with EUR 50 to 300 a month in usage. It does not replace the estimator: it turns a site visit, voice notes and photos into a structured quote built from your own price library, which the owner reviews and approves. The realistic gain is going from 2 hours to 20 minutes per quote, with margin checked line by line.
What an AI quoting assistant costs in 2026
| Item | Simple version | Connected version | Advanced version |
|---|---|---|---|
| Structuring the price library | EUR 2,000 | EUR 3,500 | EUR 5,000 |
| Note input (text, voice, photos) | text | text + voice | text + voice + annotated photos |
| Line item and quantity generation | EUR 3,000 | EUR 4,500 | EUR 7,000 |
| Margin check per line | EUR 1,500 | EUR 2,500 | EUR 4,000 |
| Software link (Xero, Sage, estimating tools) | PDF export | export + import | full sync |
| Legal terms and VAT (13.5%, 23%, RCT) | EUR 1,500 | EUR 2,000 | EUR 3,000 |
| Total project excl. VAT (2026 estimate) | EUR 8,000 | EUR 15,000 | EUR 25,000 |
| Monthly usage cost (API, hosting) | EUR 50 | EUR 120 | EUR 300 |
Plan for 6 to 10 weeks, two of which are spent testing on 30 to 50 real signed quotes to measure the gap between the AI and the human quote.
Reliability: where AI helps and where it gets things wrong
| Task | Observed reliability (estimate) | Role of human review |
|---|---|---|
| Picking items from the library | 85 to 92% | check finish variants |
| Quantities from entered measurements | 90 to 95% | check units (m², linear m, each) |
| Quantities estimated from photos | 60 to 75% | manual take-off required |
| VAT rate by type of work | 95% with coded rules | confirm with accountant |
| Forgotten items (skip hire, protection) | cut by 40 to 60% | checklist per job type |
| Unit prices | 100% if taken from the library | quarterly price update |
The rule is simple: the AI never sets a price, it selects items you have already priced. That is what makes the output reliable and the margin verifiable.
Prerequisites before starting
Your price library must be current: 300 to 800 clearly named items, with cost, markup and selling price. If it is scattered across Word or Excel quotes, structuring takes 2 to 3 weeks and is a large share of the budget. You also need to define the mandatory terms: insurance, payment terms, deposit and validity period.

Mini case study
Ciarán, owner of a 12-person renovation firm in Dublin, produces 25 quotes a month and spends 10 hours a week on them, about 43 hours a month. He picks the connected version at EUR 15,000, with EUR 120 a month in usage. After two months, each quote takes 25 minutes including review: 10.5 hours a month instead of 43. Valued at EUR 55 an hour, the 32 hours freed are worth EUR 1,760 a month, or EUR 1,640 net. The margin check also uncovers 3 items sold below cost, corrected in the library. The project pays back in 9 months, and Ciarán answers enquiries in 48 hours instead of a week, which lifts his win rate.
FAQ
Can the AI produce a quote without review? No. Human review remains mandatory, especially for estimated quantities and finish variants. It takes 10 to 15 minutes per quote.
Which quoting software is compatible? Xero, Sage and most estimating tools used in Ireland support import by file or API. Full sync adds EUR 3,000 to 5,000.
How much does monthly usage cost? Between EUR 50 and 300 a month depending on quote volume and use of voice or photo recognition. At 25 quotes a month, API cost stays under EUR 60.
Is our pricing data confidential? Yes, if the API excludes training on your data and hosting is in Europe, in line with GDPR. Your library remains your property.
Do we need a complete price library? You need at least 300 items covering 80% of your jobs. The rest can be added over time.
