How to set up retention and expansion: step-by-step tutorial for fintech in Latin America

This edition of the Growth Broker playbook is written for heads of growth and revenue at regulated fintech companies operating in Latin America. In this market, LATAM buyers reward hands-on partnership, local presence, and clear commercial terms, so the way you install retention and expansion has to be shaped to that reality from day one.

This is the exact sequence we use to install retention and expansion when a client says "we want this live by Monday". Retention and expansion is keeping and growing the customers you already paid to acquire, 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 retention and expansion, that trigger connects directly to gross and net revenue retention.

Inside fintech, the binding constraint is almost always access to buyers gated by compliance, not lack of demand, and in Latin America it is compounded by the fact that local partnership depth, not marketing spend is what actually gates growth. Retention and expansion is only useful here when it is pointed at both constraints at once.

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 gross and net revenue retention 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 treating CS as a support cost centre — 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 fintech in Latin America: one qualified fintech opportunity typically justifies a full quarter of program spend, and one properly-installed LATAM account becomes a reference across the region. That is the reason it is worth installing retention and expansion deliberately for this market rather than importing a playbook designed for somewhere else.
