What determines WordPress migration cost and timeline?
Pages are only one variable. Integrations, content quality and approval speed matter just as much.
A five-page site can be harder to migrate than a fifty-page blog if those five pages contain custom calculators, membership logic or complex forms.
The real scope drivers
Useful estimates consider page families, content volume, design change, third-party integrations, forms, SEO risk, languages and stakeholder review.
Why discovery saves money
A short audit reveals hidden dependencies before a fixed scope is signed. It also separates must-preserve behavior from features that no longer serve the business.
Use milestones
Inventory, design system, representative templates, content migration, verification and launch create clearer approval points than a single long build.
Count page families, not pages
Cost grows with the number of distinct templates, content structures and behaviours. A thousand consistent posts can be simpler than twenty pages built individually. Media cleanup, multilingual relationships, author data, taxonomies and malformed legacy markup add migration work even when the visual design remains modest.
Dependencies create uncertainty
Forms, payments, membership, search, CRM connections, gated downloads and custom plugin behaviour must be discovered and accepted separately. Access delays and slow approvals also affect the calendar. A responsible proposal identifies assumptions and exclusions instead of hiding uncertainty inside a single optimistic date.
- Audit first and price against an inventory.
- Approve representative templates before bulk migration.
- Assign one decision-maker and response window.
- Separate defect correction from new scope.
Use starting prices as filters, not promises
At BBWP, a focused migration with a straightforward structure starts from €2,500. A conversion-led business site, multilingual content or connected systems typically starts from €5,000. These are useful qualification points, not quotes: the audit still determines what must be preserved, redesigned, integrated and verified. Bespoke AI and operational systems are priced after the workflow and risk boundaries are mapped.
Read a proposal for risk
Look for milestones, acceptance criteria, redirect ownership, content responsibilities, launch and rollback plans, payment schedule and post-launch support. The cheapest headline price is not necessarily the lowest project cost if essential migration work appears later as change requests.
A useful proposal should also say what is not included. Content rewriting, brand work, paid third-party licenses, historic data cleanup and new business logic are common sources of accidental scope. Clear exclusions make comparisons fairer and protect both sides from a low headline estimate that cannot survive discovery.
