The verdict in three sentences
In 2026, a Dublin accounting firm pays 15 to 50 EUR per user per month for a SaaS document management system, or 25,000 to 60,000 EUR for a custom build with automated collection. OCR and auto-collection add 8,000 to 18,000 EUR but remove up to 60 % of collection time and cut the close by 8 days. On a firm of over 10 people, the investment pays back in under two financial years.
DMS functions and 2026 prices
An accounting DMS is not just storage: it collects, indexes, archives legally and automates client chasing. Here are the blocks and their 2026 costs.
| 2026 function | SaaS DMS | Custom |
|---|---|---|
| Storage + indexing | included | 10,000-20,000 EUR |
| Auto-collection + OCR | +5-15 EUR/user/mo | +8,000-18,000 EUR |
| Automated client reminders | option | +4,000-9,000 EUR |
| 10-year legal archiving | included | +5,000-12,000 EUR |
| Secure upload portal | option | +6,000-14,000 EUR |
| Overall price | 15-50 EUR/user/mo | 25,000-60,000 EUR |
Probative-value legal archiving over 10 years is a non-negotiable requirement: check it is native, not a mere backup.
Quantified gains: DMS ROI in 2026
A DMS's value is measured in recovered hours and days shaved off the close. 2026 order of magnitude for a 12-staff firm.
| Indicator | Before DMS | After DMS |
|---|---|---|
| Document collection time | 100 % | -60 % |
| Average close time | 22 days | 14 days |
| Manual reminder emails/mo | 340 | 80 |
| Admin hours/week | 18 h | 7 h |
| Annual cost of lost time | 45,000 EUR | 17,500 EUR |
That is roughly 27,500 EUR/year of recovered capacity, against the 40,000-60,000 EUR of a custom build paid back over two financial years.

Mini case study
Sophie, partner of a 12-staff accounting firm in Dublin's Docklands, lost 11 hours/week on collection and document chasing. We delivered a custom DMS at 48,000 EUR with OCR and an upload portal. Result: collection cut by 60 %, close reduced from 22 to 14 days, and 11 hours/week freed, i.e. about 520 hours/year at 55 EUR/loaded hour = 28,600 EUR/year. The DMS pays back in 20 months, not counting higher client satisfaction.
FAQ
How much does a custom DMS cost in 2026? From 25,000 to 60,000 EUR depending on modules. With OCR and an upload portal, expect 45,000-55,000 EUR for a mid-sized firm.
Is a SaaS DMS enough? For a small firm yes, at 15-50 EUR/user/month. Past 10 staff, custom offers finer auto-collection and better close-time gains.
What ROI to expect from OCR? A 40 to 60 % cut in collection time, often 20,000 to 30,000 EUR/year of regained capacity on a 12-person firm.
Is 10-year legal archiving included? In SaaS often yes, verify it. In custom, plan 5,000 to 12,000 EUR for compliant probative-value archiving.
What are the rollout timelines? 2 to 4 weeks for a SaaS DMS, 2 to 4 months for custom with document migration and OCR setup.
