Expansion revenue is the cheapest growth an agency has, but heavy-handed upsells cost trust. The trick is to upsell from results, not quotas.
Earn the right first
Upsell after you have delivered, not before. A win is the best setup for “here is what is next.”
Tie it to their goals
Frame the add-on as the next step toward an outcome they already want — not a new line on the invoice.
Make the margin work
Confirm the margin on the added service before you pitch it, so expansion does not erode profit.
Bill it cleanly
Add-ons should flow into recurring billing immediately. HubWho handles plan changes without manual reconciliation.
