Upselling Complementary Products & Services
Complementary products — items customers buy separately but use together — are an easy way to grow revenue. The play: remind customers of a recent purchase, offer a small incentive, and recommend the natural pairing (think cereal and milk, or a harness and a car tether).
Franpos recommends SMS and email for this, with free, industry-specific templates. Keep it fair — pair genuinely complementary items rather than artificially splitting a product — and you’ll grow sales while keeping customer trust.
