Client Support Retainer Proposal Pack With AI (Post-Project Playbook)

You closed hypercare. The client liked the work. Now the pings continue: “Can you tweak this?” “Something broke.” “We have a new idea.” If you answer for free, you rebuild the same margin leak you fixed during 30-day hypercare. If you say no without a path, they feel dropped.

This guide is the commercial bridge: a client support retainer proposal pack with AI you can ship in one afternoon. You will define what ongoing support includes, put it in a one-page Google Doc, and send a Gmail proposal the client can approve in writing. Tools: ChatGPT, Google Docs, and Gmail. You review every number and click send yourself.

Why a retainer proposal is not “just hourly”

Hourly without a written scope invites the same arguments as scope creep mid-project. A retainer works when it names:

• Included work (bug fixes on delivered build, small content swaps, office hours)
• Capacity (hours per month or response-only tier)
• SLA (business-day response, not 24/7 unless paid)
• Overflow (what happens when the bucket is empty)
• Exit (how either side ends the plan)

This is not your weekly status email cadence during active delivery, and not a change request—though CR rules still apply when they ask for new outcomes.

You will leave with:

• A Retainer Scope one-pager in Google Docs
• Three tier options (light / standard / priority) drafted with ChatGPT
• A Gmail proposal with start date and approval line
• A simple triage rule for inbound requests

What you need before drafting

• Hypercare closure summary or handoff doc
• Your real hourly rate and minimum monthly fee
• List of systems you will (and will not) touch
• Whether you want prepaid hours or fixed fee

Retainer flow (at a glance)

Step 1 — Mine reality from recent support traffic

Export or paste the last month of client emails (anonymize if needed). Note: bugs vs how-to vs new features.

ChatGPT prompt:

You are a freelance ops assistant. I want to propose a monthly support retainer after a completed project.

Paste of recent client requests (30 days):
[PASTE]

Deliver:
1) Group requests: Defect / How-to / Small tweak in scope / New feature
2) Estimated hours per month if I answered everything (range)
3) Three retainer tiers: Light (X hrs), Standard (Y hrs), Priority (Z hrs + faster SLA)
4) What should NEVER be included in any tier (bullets)
5) One paragraph positioning: why retainer beats ad-hoc hourly for this client

Plain English. No invented prices—I will add fees.

Pick one tier you would actually honor. Do not sell 20 hours if you only have 5 available.

Step 2 — Build the Retainer Scope Google Doc

Title: [Client] – Support Retainer – [Tier name]. One page:

Section A — Purpose
Support for [deliverable] delivered on [date], starting [retainer start date].

Section B — Included
Bullets: defect fixes, security patches you host, minor copy/image swaps, monthly 30-min call (optional).

Section C — Excluded
New pages, integrations, rebrands, third-party outages—link mentally to change request pack.

Section D — Capacity & SLA

Item	Value
Included hours	X/month
Response target	1 business day
Rollover	none / 1 month max (pick one)
Overage	$/hour after bucket empty

Section E — Approval
Client name, date, “Approved to start [date].”

Ask ChatGPT to tighten wording:

Turn these retainer bullets into client-friendly language for a one-page Google Doc. Firm but warm. No legal threats.
[paste your outline]

Step 3 — Send the Gmail proposal

Subject: [Client] – Proposed support retainer (reply to approve)

Hi [Name],

Now that hypercare has closed, I want a clear path for ongoing help without surprise invoices.

Please review this one-page retainer scope:
[Google Doc link]

Summary:
- Tier: [Light/Standard/Priority]
- Included: [X] hours/month for [short list]
- Monthly fee: [$ amount]
- Starts: [date] after written approval

Reply “approved” on this thread or sign the bottom of the Doc by [date]. If this is not a fit, I am happy to support ad-hoc at [$ hourly] with 48h notice.

Thanks,
[You]

Do not start retainer work until approval is in the Gmail thread or Doc.

Step 4 — Triage every inbound request

Use the same Bug / How-to / Change mental model from hypercare:

Signal	Route
Defect in delivered work	Retainer if hours remain
How-to on delivered feature	Retainer
New outcome	Change request or new SOW
Emergency “site down”	Handle once; then clarify if monitoring belongs in a higher tier

Triage prompt:

Given this retainer scope excerpt and client message, classify: Retainer-included, Retainer-overage, or New-project/CR. One recommended next sentence for the client email. No draft reply yet.

Scope:
[paste]

Message:
[paste]

Log hours in the same Doc or a simple sheet—consistency beats fancy tooling at first.

Step 5 — Month-end: reset without awkwardness

Three days before renewal, send a five-bullet summary: hours used, tickets closed, overflow (if any), renewal date, option to change tier.

If they churn, close professionally—archive the Doc and point to your hypercare closure tone: no guilt, clear end date.

Common mistakes

• Reopening hypercare under retainer pricing without saying so
• Unlimited “quick questions” with no hour cap
• No overage line—you eat every surprise
• Starting work before written yes

Quick checklist

• Tiers grounded in real request history
• Included vs excluded explicit
• Fee and start date in Gmail
• Approval captured in writing
• CR path linked for new scope
