Retention and expansion: a case study playbook for professional services firms in Latin America

This edition of the Growth Broker playbook is written for managing partners and heads of business development at consultancies and agencies 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.

Names removed, numbers preserved. This is a real retention and expansion engagement, reproduced as a playbook. Client had product-market fit, a rev team of eleven, and a stalled pipeline.

Week one: diagnosis. The stated problem was "not enough leads". The actual problem was treating CS as a support cost centre, which had been masked by inbound velocity that peaked two quarters earlier.

Weeks two to three: rebuild the target list from scratch and re-cut the trigger. Retention and expansion works when one point of NRR is worth more than five points of new logo growth; the client had drifted away from that first principle.

Inside professional services firms, the binding constraint is almost always senior partner time, not lead volume, 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.

Weeks four to six: live at 20% of previous volume, quality bar raised. Gross and net revenue retention moved every week, though absolute numbers stayed modest.

Weeks seven to twelve: ramp. By week ten the number was ahead of the pre-stall baseline. By week twelve it was 40% ahead. Cost per outcome was roughly halved.

What we would repeat: the diagnosis step, the quality bar, and the weekly review. What we would kill sooner: two tools we bought in month one that added noise instead of leverage.

The client's own summary at the end of quarter one: "we thought we needed more of everything; we actually needed less of the wrong things." That is usually the lesson.

Concretely for professional services firms in Latin America: one signed retainer typically funds the entire growth program for a year, 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.
