How to set up partnerships and co-selling: step-by-step tutorial for marketing and creative agencies

This edition is written for agency owners and heads of new business. In marketing and creative agencies, agencies sell their own outcome — the playbook has to be one they would proudly resell, so the way you install partnerships and co-selling has to reflect that reality from day one.

This is the exact sequence we use to install partnerships and co-selling when a client says "we want this live by Monday". Partnerships and co-selling is using another company's distribution to reach buyers you cannot cost-effectively reach yourself, and everything below is designed so a single operator can run it end to end.

Step one: write down the account list. If you cannot name 200 companies, you do not yet have a target — you have a demographic. Refine until every account passes a "would we take their money?" gut check.

Step two: define the trigger. What has to be true in the world for you to touch this account this week? For partnerships and co-selling, that trigger connects directly to sourced and influenced pipeline from partners.

The binding constraint we see in marketing and creative agencies is almost always owner-time bottleneck on the sales function. Partnerships and co-selling is only useful in this vertical when it is pointed at that constraint — not at a generic growth number borrowed from another category.

Steps three to five: pick the tools, wire the data, and dry-run against ten accounts. Do not scale until a human has read every artefact and would send it themselves.

Steps six and seven: go live at 20% of intended volume for one week. Track sourced and influenced pipeline from partners daily, not weekly. Kill anything that misses the bar.

Steps eight to ten: ramp to full volume, publish a Friday review, and set the next 30-day target. Do not chase new tools until the current setup has run for a full month.

The most common tutorial failure is signing MOUs no one operationalises — usually in step six, when volume feels safe and copy quality slips. Guard step six with a checklist and a second pair of eyes.

Concretely for marketing and creative agencies: agencies that install this stop trading time for pipeline and start productising it. That is the reason it is worth installing partnerships and co-selling properly rather than half-heartedly across three vendors.
