How can I use this model to secure recurring revenue?

You achieve this by bundling your service tiers into a predictable monthly fee, which effectively removes purchasing friction. For example, you can structure a monthly offer where a client makes a base commitment for your premium human and turn-key MTPE work. On top of that, you can pitch an “unlimited MT” add-on, protected by a “reasonable use” clause. By committing, they also get a big discount across all “a la carte” services, and you can manage your own risk by starting them on a three-month trial contract. The easiest place to start selling this is through a “reactivation play” aimed at clients whose volume has dropped over the last one to two years. Set the retainer close to their historical average monthly spend. This is a brilliant pitch because they do not need new budget approval, but they instantly receive amazing new value.
