The verdict in three sentences
A custom multi-role CRM web app in Singapore costs between 40,000 and 95,000 USD in 2026, with permission management and reporting as standard. Expect 12 to 18 weeks of delivery time, managed hosting of about 700 USD/month and maintenance of 15% of the build per year. It centralizes flows between teams and subcontractors and eliminates email back-and-forth.
What a custom CRM web app funds
For a group coordinating several teams and subcontractors, a custom CRM becomes the single point where records, documents and approvals flow. Each actor sees only what concerns them. The budget follows the number of modules.
| Functional module | Indicative 2026 cost (USD) | Timeline |
|---|---|---|
| Multi-role core + granular permissions | 9,000 - 16,500 | 3 wks |
| Flow management (records, requests) | 8,000 - 18,000 | 3-4 wks |
| Document space + versioning | 6,500 - 13,500 | 2 wks |
| Reporting + dashboards + exports | 5,500 - 12,000 | 2 wks |
| Audit log + traceability | 4,500 - 9,000 | 1-2 wks |
| Internal-tools integration (API) | 6,500 - 20,000 | 3-4 wks |
The low end (40,000 USD) covers the multi-role core, flow management and document space. The high end (95,000 USD) adds advanced reporting, full traceability and integrations.
Custom vs licensed SaaS over 3 years
| Item | Custom build | Licensed SaaS |
|---|---|---|
| Upfront investment | 62,000 USD | 0 - 9,000 USD (setup) |
| Monthly subscription | 0 | 1,800 - 4,000 USD |
| Hosting + maintenance | 17,000 USD/year | included |
| Permission customization | included | 6,500 - 15,000 USD |
| Total cost over 36 months | ~113,000 USD | ~70,000 - 160,000 USD |
| Code ownership | yes | no |
As soon as the SaaS subscription exceeds ~2,700 USD/month, custom build becomes competitive over 3 years, with code ownership and unlimited customization as bonuses.
Mini case study
Mr. Belkacem, operations director of a group in Singapore (construction, 5 teams, 30 subcontractors), coordinates via email and phone. Back-and-forth and lost information generate on average 12 incidents/month (delays, duplicates), each costing about 550 USD, i.e. 6,600 USD/month.
He invests 57,000 USD in a CRM web app (permissions, flow management, reporting, traceability). Incidents drop by 70%, saving 4,600 USD/month (55,000 USD/year). Return on investment in a little over one year, with an owned tool that durably smooths coordination.

FAQ
What is the difference between an extranet and an intranet?
An intranet serves your internal employees; an extranet/CRM opens secure access to external partners (teams, subcontractors) with granular rights. The build costs 40,000 to 95,000 USD depending on modules.
Is integration with our internal tools worthwhile?
Yes, to avoid double entry. Budget 6,500 to 20,000 USD depending on your tools' API quality and the number of flows to synchronize.
How long to deliver?
Between 12 and 18 weeks depending on the number of modules and permission granularity. The multi-role + flows core ships in 12 weeks; adding integrations pushes it to 16-18 weeks.
Custom or licensed SaaS?
For a standard need, SaaS is enough. But as soon as permission rules or workflows are specific, custom build avoids costly workarounds. Above ~2,700 USD/month in subscription, custom build is often more cost-effective.
What maintenance budget?
Plan on 15% of the build per year, i.e. around 8,500 USD/year for a 57,000 USD build, plus managed hosting (~700 USD/month).
