A single counterpart model does not pile every task onto one person. The people who ship the page, connect the form and run the ads read the same priority list. A managing director stops explaining one fault in three briefs.
The leak sits between the tables
The page is live, the click is bought, the CRM field is still “later”. Each supplier looks finished. The enquiry closes at nobody’s table. One counterpart keeps page, integration and campaign on one record. Without the record the title is only a title.
The decision stays in the company
The sequence needs the internal decision-maker’s approval. The partner prepares the list, marks collisions and writes what is out of the written scope. If that person rewrites the brief every week, the model breaks. The missing piece is the sequence, not a grander job title.
Accounts are not opened in the partner’s name
Code ownership stays with the company. The ads account, the domain and the repository sit in the company’s name. Account ownership stays with the company. The counterpart has access and is not the owner. Handover day is not a password hunt. The list is an annex to the written scope.
One table, not three realities
HED Creative is the accountable partner in Berlin and Ankara. Web, software and Google Ads share the month’s sequence. Separate invoices are fine. Separate versions of the truth are not. Measurement counts the enquiry once.
The written model starts at IT partner. What happens when three suppliers point at each other: agency stack.
