The verdict in three sentences
The real work of real estate agency software is not the CRM but integration: accounting API, listing portals, e-signature and property management must talk to each other. Each custom connector costs 12 000 to 25 000 EUR and removes manual reconciliation valued at 9 h/week. The whole set deploys in 8 to 14 weeks, compliant hosting included.
The network's integration matrix
Before pricing, map who exchanges what with whom. A clear matrix avoids useless connectors and prioritises those that save time immediately.
| Source system | Target system | Exchanged flow | Priority |
|---|---|---|---|
| Transaction software | Accounting ERP | sales/commission entries | high |
| Transaction software | Listing portals | mandate publishing | high |
| E-signature | Transaction software | signed contracts | high |
| Property management | Accounting ERP | receipts/rents | medium |
| Accounting ERP | Dashboard | consolidated KPIs | medium |
| CRM | Emailing | prospect follow-ups | low |

Cost per connector and associated gain
Each connector is a mini-project with its own cost, lead time and gain. Prioritising by ROI avoids building everything at once and spreads the investment.
| Connector | Custom cost | Measured gain |
|---|---|---|
| Accounting API (auto entries) | 15 000 - 25 000 EUR | -9 h/wk reconciliation |
| Multi-portal listing publishing | 12 000 - 18 000 EUR | mandates online in 1 click |
| E-signature | 8 000 - 14 000 EUR | -3 days on signed mandates |
| Property-management connector | 12 000 - 20 000 EUR | automated receipts |
| Consolidated 4-branch dashboard | 10 000 - 16 000 EUR | real-time network steering |
| Annual maintenance (15 %) | variable | keeping connectors alive |

Mini case study
Julien is the finance director of a 4-branch real estate network in Montreal. He prioritises three connectors: accounting API (20 000 EUR), e-signature (11 000 EUR) and multi-portal publishing (15 000 EUR), i.e. 46 000 EUR one-off plus 6 900 EUR/yr maintenance. The 9 h/week reconciliation saving, valued at 40 EUR/loaded hour over 45 weeks, is 16 200 EUR/yr. Adding the 3 days saved per signed mandate (faster transaction turnover) and the end of cross-branch re-keying, net gain exceeds 22 000 EUR/yr. Payback on the 46 000 EUR lands in just over 24 months, while making the 4 branches' consolidated accounting reliable.
FAQ
How much is an integration connector? Around 12 000 to 25 000 EUR per custom connector depending on the target API's complexity and the volume of flows to synchronise.
Which connector should come first? The one with the best ROI: the accounting API, which alone removes the 9 h/week of manual reconciliation between transaction and ERP.
What is the deployment timeline? A core of 2-3 connectors delivers in 8 to 14 weeks, including tests and acceptance with the branch teams.
Does e-signature really save time? Yes: it cuts the delay between agreement and signed mandate by 3 days, accelerating transaction turnover.
Is the hosting compliant? Yes: the software and its connectors run on regional infrastructure with encryption at rest and an access log for client data.
