Retainer
A recurring payment arrangement where a client pays a fixed monthly fee for ongoing access to a service or a defined scope of work.
A retainer is a service contract where the client pays a fixed amount each month in exchange for ongoing work, availability, or a predefined scope of services. It converts project-based income (unpredictable) into recurring income (predictable).
Retainer vs project work: - Project: You build a chatbot for $1,000. Payment is one-time. After delivery, the relationship ends. - Retainer: You build the chatbot for $500 setup, then charge $150/mo to monitor it, fix issues, and add one new flow per month. The relationship — and income — continues indefinitely.
Why retainers are valuable for service businesses: - Predictable income makes it easier to plan and grow - Clients stay longer because switching has friction - The ongoing relationship surfaces upsell opportunities naturally
Common retainer services in AI/automation: - Zapier or Make.com automation maintenance - AI chatbot monitoring and updates - LinkedIn ghostwriting (monthly content calendar) - AI content writing (X pieces per month)
Pricing retainers: Charge based on the value delivered, not the hours worked. A retainer that saves a client 10 hours/mo is worth far more than the hourly rate of 2 maintenance hours.
Example
You build a lead-routing automation for a real estate agency for a $400 setup fee. You offer a $150/mo retainer to monitor the Zaps, fix breaks, and add one new workflow per month. With 6 retainer clients, that's $900/mo in recurring income requiring ~3 hours of work.
