Existing SaaS
Potential speed and operational simplicity, provided the selected vendor supports your workflow, API and data constraints.

customer portal?
Build or buy a B2B customer portal? Compare SaaS, hybrid ERP integration and custom development using practical procurement questions. Then use the free six-question tool for an initial recommendation and a three-part PDF, without creating an account.
Three competing paths.
A real decision depends on workflows, integrations, delivery windows, ownership and regulation. None is automatically superior.
Hybrid architecture
Reuse a product for the standard functions while adding custom integration or processes around it.
Explore ERP integrationCustom application
Maximum design flexibility may introduce greater delivery, security and long-term maintenance responsibilities.
See custom engineeringWhat the checks actually show.
Explore the assumptions behind the model. These examples test specific behaviors, not real vendors.
Role-based accessHow permissions behave across different accounts.
Positive, negative and cross-tenant authorization examples. Demonstrates expected policy behavior, not a security certification.
ERP failure handlingWhat happens when an integration request fails.
Deterministic retry outcomes for transient, invalid and exhausted responses. No real network or ERP integration was measured.
Audit trail integrityWhether a changed audit record can be detected.
Small append-only hash-chain examples with a tamper detection case. This is not a production-grade authenticated audit log.
Deterministic assertions executed on policy functions; not a SaaS-vs-custom performance benchmark. The examples do not demonstrate that any commercial SaaS, ERP or custom vendor is faster, cheaper or more secure.
Reproducible
by design.
The decision engine exposes every adjustment. The behavioral checks are deterministic and executable again without customer data, API tokens, or paid AI models.
Source-controlled assumptions and test fixtures.
Repeatable local assertions, recording both successes and failures.
Inspectable, machine-readable JSON output.
Before you choose a portal.
Practical answers about SaaS, custom development and ERP integration. The results depend on the actual systems and contracts.
Should I build or buy a B2B customer portal?
Start by checking whether an existing product supports your actual workflows, permissions and ERP integrations. Standard account access and document sharing may favor configuring SaaS. Unusual approval rules or multi-system dependencies may justify hybrid or custom development. This tool provides a directional assessment, not a vendor selection.
When does a hybrid customer portal make sense?
A hybrid approach can keep standard features in an established SaaS or business platform while a custom integration or interface supports your unique processes. Confirm which system owns each data field, which team maintains each integration and what happens when the ERP is unavailable.
How do I compare SaaS and custom customer portal costs?
Compare the full cost of ownership rather than an initial quote alone: licensing, implementation, integration, hosting, maintenance, security reviews and ongoing changes. This pilot does not estimate prices or validate vendor quotations.
What should I test before connecting a customer portal to an ERP?
Define authorization boundaries, ERP API permissions, data ownership, retry limits and the handling of rejected or duplicated requests. The accompanying open tests illustrate synthetic RBAC, retry and audit-log behavior; they are not tests of a real ERP or a certified security system.
What costs do B2B SaaS portal subscriptions leave out?
Check licenses, API and integration tiers, ERP connector maintenance, staff training, customer-specific changes, support, security reviews and eventual data export. Compare the full cost of ownership over the same period, not a subscription against a one-time development quote.
Can a B2B dealer portal connect to SAP, Logo or Mikro?
Compatibility depends on the specific ERP version, modules, available APIs, licensing and network permissions. Require documentation and a realistic sandbox test before assuming any SaaS connector or custom interface will work. Mihenk does not claim a certified connector to these systems.
What does a multi-branch B2B order portal need?
Define separate buyer and approver roles, branch-specific pricing, purchase limits, order visibility, credit rules and the ERP system of record. Test cross-branch isolation and rejected or duplicated orders; a shared catalog alone is not enough.
Go deeper into the constraints.
Separate buying decisions need separate evidence. Start with the issue that can block your project.
