The verdict in three sentences
For a Dublin manufacturer managing 600 suppliers, a custom supplier portal connected to SAP costs 70,000 to 154,000 EUR with an Irish agency billing 100 to 140 EUR per hour, or 45,000 to 120,000 EUR with a nearshore team, deployed in 4 to 7 months. Source-to-pay suites such as Ivalua or Coupa cover a broader scope, but charge 25,000 to 80,000 EUR a year in licenses, plus integration that often costs as much as a custom build. With 1,200 hours of supplier chasing saved per year and better competitive tendering, payback is measured in months, not years.
The modules of a manufacturing supplier portal
A manufacturer's procurement team spends a large share of its time chasing documents: tax clearance certificates, ISO 9001 and ISO 13485 certificates, REACH and RoHS declarations, insurance certificates, order acknowledgements. A portal centralizes these exchanges and makes them traceable. Here are 2026 ballpark figures for a nearshore team; an Irish agency typically quotes 30 to 55 % more for the same scope.
| Module | Function | Cost (EUR) | Duration |
|---|---|---|---|
| Supplier onboarding | Supplier profile, CRO number, bank details, tax clearance, internal approval | 6,000 to 15,000 | 3 to 4 weeks |
| Certificate management | ISO, REACH, insurance uploads, expiry alerts at 60 and 30 days | 5,000 to 12,000 | 2 to 3 weeks |
| Tenders and RFQs | Online RFQ, comparison grid, bid history | 10,000 to 28,000 | 4 to 6 weeks |
| SAP-connected order tracking | Purchase order publishing, acknowledgements, confirmed dates | 12,000 to 32,000 | 5 to 8 weeks |
| Invoices and payments | Processing status, expected payment date, disputes | 5,000 to 13,000 | 2 to 3 weeks |
| Supplier performance | On-time delivery, non-conformities, annual scoring | 4,000 to 10,000 | 2 weeks |
| Security and acceptance | Strong authentication, per-site permissions, load testing | 3,000 to 10,000 | 2 weeks |
The SAP connector carries most of the risk. With SAP S/4HANA, standard OData APIs simplify the exchange of orders and acknowledgements; with an older ECC system, IDocs or intermediate files are often needed, adding 30 to 40 % to that module. The internal or external SAP integrator must be involved from scoping.
One point on e-invoicing: Ireland already requires Peppol-compatible e-invoices for public sector suppliers, and the EU ViDA package will extend structured e-invoicing to cross-border B2B trade by 2030. The portal does not replace an access point, it displays processing and payment status, which removes most anxious supplier calls.
Custom build or SaaS suite: the five-year math
Source-to-pay suites are designed for large groups that want to cover the full procurement cycle, from contracts to spend analytics. For a mid-sized manufacturer that mainly needs smoother supplier collaboration, the comparison should run over five years.
| Criterion | SaaS suite (Ivalua, Coupa, equivalents) | Custom portal (nearshore) |
|---|---|---|
| Annual licenses | 25,000 to 80,000 EUR | 0 EUR |
| Initial integration and configuration | 20,000 to 60,000 EUR | Included in 45,000 to 120,000 EUR |
| Hosting and maintenance per year | Included | 7,000 to 15,000 EUR |
| Five-year total cost | 145,000 to 460,000 EUR | 80,000 to 195,000 EUR |
| Implementation time | 6 to 12 months | 4 to 7 months |
| Functional coverage | Very broad: contracts, spend, catalogs | Focused on your real processes |
| Adoption by SME suppliers | Standard interface, sometimes seen as heavy | Simplified journeys |
The SaaS suite remains the right choice for a multi-country group needing consolidated spend analytics. Custom wins when suppliers are mostly regional SMEs, when processes are specific (subcontracting, tooling, made-to-drawing parts) and when IT wants to keep control of the data.
The conditions for a successful rollout
A portal is only worth its adoption rate. Three rules recur in projects that work. First, onboard the 50 suppliers who account for 80 % of volume before opening to the other 550. Second, make the portal mandatory for one specific flow, for example order acknowledgements, from month three. Third, track every month the share of up-to-date documents and the average RFQ response time, so leadership sees the gains.

Siobhán Murphy, procurement director at a medical device manufacturer in west Dublin, manages 600 suppliers and 40 million euros of annual spend. Her team spends 1,200 hours a year chasing certificates and acknowledgements, at a 45 EUR fully loaded hourly cost, or 54,000 EUR.
She chooses a nearshore custom portal at 85,000 EUR, with 11,000 EUR a year of maintenance. By routing 8 million euros of spend through better-run online tenders, she targets a cautious 1 % saving, or 80,000 EUR a year. Total annual gain: 54,000 plus 80,000 minus 11,000, or 123,000 EUR. The project pays back in 8.3 months. Over five years, compared with a SaaS suite at 50,000 EUR of annual licenses and 40,000 EUR of integration, the gap exceeds 150,000 EUR.
FAQ
Can the portal connect to an older SAP version?
Yes, through IDocs, BAPIs or scheduled exchange files. Expect 30 to 40 % more on the order tracking module, so 16,000 to 45,000 EUR instead of 12,000 to 32,000 EUR with S/4HANA.
Does the portal replace a Peppol access point?
No. Structured e-invoices travel through a certified access point. The portal displays processing status and cuts supplier calls about payments by 50 to 70 %.
How long until it is operational?
Plan on 4 to 7 months: 4 weeks of scoping with procurement and IT, 12 to 20 weeks of development, then a 4-week pilot with 50 suppliers before general rollout.
How do we get suppliers to use it?
By making one flow mandatory and keeping access simple: secure link login, no installation, clear journeys. Well-run projects reach 80 % active suppliers within 6 months.
What maintenance budget should we plan?
Between 8 and 12 % of the initial budget per year, so 7,000 to 15,000 EUR, including EU hosting, backups and minor enhancements.
