Estimate a B2B supplier portal for onboarding, certificates, tendering, purchase orders and ASN.
Supplier portal costs
The Supplier Portal cost calculator provides an immediate, non-binding cost range without requiring an email address or registration. It combines your project inputs with documented calculation rules and experience from more than 250 software projects.
Use the calculator right below for an instant first estimate – no sign-up and no fixed-price commitment. We align scope, risks, and assumptions in a conversation before a binding quote.
The calculation follows six visible stages. All figures remain planning values until scope and assumptions have been reviewed.
1. Capture inputs
The calculator records the visible project, volume, complexity and operating parameters selected on this page.
2. Add fixed components
Fixed base modules and selected add-ons are added without mixing them with recurring charges.
3. Apply multipliers
Quantity, complexity and scope factors multiply only the cost components identified for them in the calculator model.
4. Create the range
The calculator applies its documented lower and upper uncertainty factors to the base result; ROI views keep investment and savings visible separately.
5. Round and calibrate
Monetary result fields are rounded to the nearest whole euro. Public project-cost components are calibrated with the centrally maintained display factor.
6. Classify the result
The result is shown as non-binding guidance. A binding quote requires scope, data, integrations, risks and acceptance criteria to be reviewed.
Efficiency or discount factor: A central display factor of 0.7 is applied to public project-cost components to keep all calculators aligned with the currently reviewed pricing basis. It is not a customer-specific discount; customer-entered wages, revenues and existing operating costs are not reduced.
Why this is not a binding quote: The calculator cannot verify complete requirements, third-party dependencies, data quality, legal constraints or acceptance criteria.
Supplier portal costs depend on onboarding, certificates, procurement workflows, and ERP integration.
A staged rollout protects procurement operations and gives less digital suppliers a clear transition path.

FAQ
A focused onboarding and document portal commonly starts in the mid five-figure range.
Tendering, purchase orders, ASN and deep procurement ERP integration raise the scope. The figure stays a non-binding planning range.
A supplier portal serves procurement: qualification, certificates, tenders, order confirmations and advance shipping notices.
A customer portal serves sales, service and buyer-side ordering instead.
A practical MVP covers supplier onboarding, roles, master data, certificate workflows and secure document exchange.
Orders, ASN and tendering follow later. Add them once the effect on purchasing is measurable.
Digitise supplier collaboration
We align the portal with procurement, ERP and your supplier structure.
APIs or an integration layer synchronise supplier records, orders, line items, delivery dates and status.
ASN and order confirmations need explicit field mappings. They also need error queues and a named owner for each process.
The portal records validity, mandatory documents and approval status per supplier.
Automated reminders and blocking rules cut spreadsheet work. The purchasing team still reviews and approves every certificate.
Start with a pilot group of strategic suppliers to confirm workflows and data.
Then invite the rest in segments with short guidance. Suppliers that are not fully digital yet get a clear transition path.
| Model | When it fits | Budget & flexibility | Typical risks |
|---|---|---|---|
| Fixed price (fixed scope) | Clearly defined scope, stable requirements, repeatable delivery. | Predictable total cost; little room for change without a change order. | Scope creep leads to change orders or quality trade-offs. |
| Time & Material | Discovery, legacy, evolving requirements, or close collaboration. | Maximum flexibility; budget transparent via hourly or daily rates. | Without prioritisation, effort can grow—backlog and reviews matter. |
| Retainer / maintenance package | Ongoing operations, updates, small features, and support. | Agreed capacity per month; predictable follow-on cost. | Large changes may still need a separate estimate. |
| Hybrid (milestone + T&M) | MVP or phased releases with clear go-lives, then iterate. | Core delivery fixed price; extensions on a time-and-materials basis. | Define contractually what is in scope vs. extra work. |
Calculators on this page provide indicative ranges; we choose the right model with you based on risk, scope, and planning horizon.

What does digitising supplier collaboration cost?
Interactive estimate based on your inputs.
Non-binding project range from the software cost calculator: EUR 10,332 – 372,623 excl. VAT.
Methodology: The estimates are based on historical project data, complexity drivers and standard implementation assumptions. Results are a non-binding indication only; effort and price must be calculated individually.
If you are still deciding
If you are ready to implement
A transparent four-step process for validating the Supplier Portal indication with concrete requirements.
1. Confirm scope and target outcome
We clarify the business outcome, user groups, and boundaries relevant to Supplier Portal.
2. Review data, interfaces, and risks
We validate integrations, data quality, security, compliance, and operational dependencies.
3. Check the calculator assumptions
We compare the selected parameters with the real system landscape and document deviations.
4. Prepare the precise quote
You receive a scoped proposal with milestones, exclusions, price model, and next decision point.
