The verdict in three sentences
For a mid-sized company managing 1,800 active contracts, a custom contract management app costs between USD 33,000 and 71,000 one-off, while an off-the-shelf CLM charges USD 27,000 to 55,000 per year in licenses. The investment usually pays back within 12 to 24 months, especially if the app prevents 3 to 5 unwanted automatic renewals each year. The real challenge is not the tool but the migration of the 1,800 contracts and the quality of the metadata (dates, notice periods, amounts) captured at the start.
Custom build or off-the-shelf CLM: the 2026 numbers
CLM vendors primarily target large enterprises. For a legal team of 3 to 6 lawyers in New York, per-seat licensing and add-on modules quickly inflate the bill. A custom build flips the model: a build cost, then predictable maintenance.
| Criterion | Off-the-shelf CLM (SaaS) | Custom application |
|---|---|---|
| Upfront cost | USD 5,500 to 16,500 for configuration | USD 33,000 to 71,000 |
| Annual cost | USD 27,000 to 55,000 in licenses | USD 5,000 to 10,000 for maintenance and hosting |
| 3-year cumulative cost | USD 88,000 to 181,500 | USD 48,000 to 101,000 |
| Users | Billed per seat (USD 65 to 165/month) | Unlimited (legal, procurement, operations) |
| Fit with internal workflows | Limited to available settings | Approval flows specific to the company |
| Data ownership | Vendor hosting, export sometimes charged | Dedicated database, US hosting |
| Go-live time | 2 to 3 months | 4 to 6 months |
2026 order of magnitude: beyond 10 regular users, custom becomes cheaper from the second year.
What the app should cover, module by module
Scope is built around the contract lifecycle: request, drafting, approval, signature, execution, expiry. Each module has an indicative cost.
| Module | Function | Indicative cost |
|---|---|---|
| Contract repository | Contract record, parties, amounts, attachments, full-text search | USD 7,700 to 13,000 |
| Version control | Amendment history, version comparison, locking | USD 4,400 to 8,800 |
| Expiry alerts | Reminders at D-120, D-90 and D-30 before notice deadline, escalation to manager | USD 3,800 to 7,700 |
| Approval workflow | Lawyer, CFO, CEO depending on amount threshold | USD 5,500 to 11,000 |
| E-signature | DocuSign or Adobe Sign connector, compliant with the ESIGN Act | USD 3,300 to 6,600 |
| Legacy migration | Import and qualification of the 1,800 contracts | USD 4,400 to 13,000 |
| Dashboards | Commitments by supplier, contracts to renegotiate, risks | USD 3,800 to 11,000 |
Legacy migration is often underestimated. Extracting notice dates from a 40-page PDF contract takes a lawyer 10 to 20 minutes. AI-assisted extraction with human validation cuts that time by three.
Typical timeline and watch points
A 4 to 6 month project breaks down into four stages: scoping (3 to 4 weeks), development in increments (10 to 16 weeks), data migration in parallel, and user acceptance testing with the legal team (3 weeks). Three points deserve special attention:
- Access rights: an employment agreement or shareholders' agreement must not be visible to operations staff. Plan rights by contract type and by entity.
- Privacy and security: contracts contain personal data. US hosting, access logs, configurable retention periods and SOC 2 aligned practices.
- Integrations: link with the procurement ERP to attach invoices to contracts, and with the corporate directory for single sign-on.
Mini case study
Claire, general counsel of a food manufacturing company in New York, manages 1,800 contracts with a team of four lawyers. Last year, five maintenance and leasing contracts renewed automatically for lack of an alert, at a combined extra cost of USD 68,000. She compares two options over three years:

- Off-the-shelf CLM: USD 8,800 configuration + 3 x USD 42,000 licenses = USD 134,800.
- Custom application: USD 57,000 development + 3 x USD 7,700 maintenance = USD 80,100.
The gap is USD 54,700. If the app prevents just three unwanted renewals per year, at USD 13,000 on average, the annual gain reaches USD 39,000. The custom project pays back in about 18 months, not counting time saved by lawyers on document searches (estimated at 4 hours per week per lawyer).
FAQ
How much does a custom contract management app cost in New York in 2026?
Expect USD 33,000 to 71,000 depending on the number of modules and the volume of contracts to migrate. A core build with repository, alerts and e-signature starts around USD 33,000.
How long does it take to go live?
Between 4 and 6 months, including data migration. A first version with repository and alerts can be used from week 10.
How does the app prevent automatic renewals?
Each contract carries its expiry date and notice period, and the app calculates the termination deadline. Reminders go out at D-120, D-90 and D-30, with escalation if nobody handles the alert.
Is an e-signature as valid as a handwritten one?
Yes, under the ESIGN Act and New York's Electronic Signatures and Records Act, e-signatures are legally binding for most commercial contracts. Cost per signature is typically USD 1 to 3.
What happens to contracts already signed?
They are imported during migration, with key dates extracted and validated by a lawyer. For 1,800 contracts, plan USD 4,400 to 13,000 depending on the level of automation.
