The verdict in three sentences
When 1,600 active contracts live in Excel, every missed notice period auto-renews a contract for a year that nobody wanted to keep. A custom application costs, as a 2026 order of magnitude, USD 33,000 to 66,000 (EUR 30,000 to 60,000), delivered in 3 months, while an off-the-shelf CLM platform runs USD 16,500 to 44,000 per year. By targeting on-time terminations and renegotiations, a finance team can avoid up to 5% of the supplier spend concerned, which pays back the project within a fiscal year.
Custom build or CLM software: compare over three years
A port services group, whether in Marseille or at PortMiami, manages very mixed contracts: crane maintenance, equipment rental, security services, energy, telecoms, cargo handling subcontracting. Market CLM tools are built for legal departments and often bill per user. A custom app fits your procurement process and your ERP.
| Criterion | Shared Excel | Market CLM software | Custom application |
|---|---|---|---|
| Upfront cost | USD 0 | USD 5,500 to 16,500 setup | USD 33,000 to 66,000 |
| Annual cost | Internal time | USD 16,500 to 44,000 licences | USD 3,300 to 9,900 (hosting + maintenance) |
| 3-year cost | Hidden but real | USD 55,000 to 148,500 | USD 43,000 to 96,000 |
| Notice and expiry alerts | Manual | Yes | Yes, rules per contract type |
| ERP link (commitments, invoices) | No | Generic connectors | Custom, automatic matching |
| Time to go live | Immediate | 1 to 3 months | 3 months |
| Data and code ownership | Yes | No | Yes |
Custom becomes cost-effective once you pass about twenty users (buyers, controllers, site managers) or when your notice rules are specific.
The features that actually generate savings
Not all budget lines are equal. The modules below are ranked by financial impact observed on comparable portfolios.
| Module | Indicative cost | Expected impact |
|---|---|---|
| Contract repository + Excel import | USD 6,600 to 11,000 | Single source, no more duplicates |
| Notice alerts D-120 / D-90 / D-30 | USD 4,400 to 7,700 | On-time terminations, 2 to 3% of spend |
| Renewal workflow with approval | USD 5,500 to 11,000 | Traced decision before every renewal |
| E-signature (DocuSign, Yousign) | USD 3,300 to 6,600 + USD 1 to 3 per envelope | Signing cycle from 10 days to 2 |
| ERP commitment / invoice matching | USD 8,800 to 20,000 | Price drift detection, 1 to 2% |
| CFO dashboard | USD 4,400 to 9,900 | View of commitments at 12 and 24 months |
A simple electronic signature is enough for most supplier contracts. Keep advanced or qualified signatures for high-stakes contracts, where unit cost rises to about USD 3.
A 3-month plan and watch points
Month 1: scoping, cleaning and importing the 1,600 contracts, defining notice rules by category. Month 2: alerts, workflow and signature. Month 3: ERP connection, dashboard, acceptance testing with two pilot sites. The hard part is almost always the quality of the starting Excel file: missing end dates, blank notice periods, duplicate suppliers. Plan 10 to 15 days of procurement team work to clean the data.

Nadia, CFO of a port services group, oversees 1,600 contracts representing EUR 42 million (about USD 46 million) of annual spend. About 30% of these contracts, or EUR 12.6 million, auto-renew. By terminating or renegotiating 4% of that scope on time, the group avoids EUR 504,000 a year. The project costs EUR 48,000, plus EUR 6,000 a year for maintenance and hosting, and EUR 2,400 of e-signature for 1,200 envelopes. Even counting only a quarter of the estimated savings, EUR 126,000, payback comes in under five months.
