Retainer Management & Billing

Q: How much manual review is still needed before an invoice goes out?

An internal approval step remains built in, so a team member still reviews and signs off before the invoice reaches the client.

Q: Can this work with the accounting and time tracking tools our agency already uses?

The automation is built around commonly used time tracking, spreadsheet, and accounting tools, so it fits most existing setups.

Q: What happens to our existing retainer tracker data?

Existing tracker records stay in place and the automation keeps updating them going forward instead of replacing them.

Q: How are unpaid invoices handled?

The automation monitors due dates, sends reminders when payment is late, and reconciles payment once it arrives.

Keep every client retainer reconciled and invoiced on time, without manual spreadsheet juggling.

About This Automation

Retainer billing requires pulling logged hours, checking them against contracted scope, and calculating any overage before an invoice can go out. Doing this by hand for every client each month invites errors, slow turnaround, and inconsistent scope explanations.

An automated version pulls hours, compares them to scope, drafts the invoice with adjustments applied, and routes it for approval and delivery. Payment tracking and reconciliation happen without manual follow-up, so invoices go out faster and stay accurate.

Key features:

Pulls logged hours automatically from the time tracking system for each billing period

Compares hours against contracted retainer scope and flags overage or underage

Drafts the invoice with the base fee and any scope adjustment already applied

Routes the draft for internal approval before it reaches the client

Delivers the approved invoice with a scope summary to the client

Tracks payment due dates and reconciles incoming payments automatically

How The Automation Works

The full workflow, from trigger to completion.

1. Time Tracking Data Closestrigger

Sends the closed billing period's logged hours to the automation platform for reconciliation.

2. Reconciliation Drafts Invoice

The Retainer Reconciliation compares logged hours to the client's scope, flags any overage, and creates a draft invoice.

3. Finance Manager Approves

Invoices that exceed the client's auto-send threshold are routed to the finance manager for a quick approve or reject.

4. Invoice Delivery Sends Invoice

Once approved or auto-cleared under threshold, the Invoice Delivery emails the invoice and logs it retainer tracker.

5. Payment Follow-up Sends Reminder

If the invoice is still unpaid after the due date, the Payment Follow-up sends a reminder email.

6. Reconcile Payment

Once payment lands, the automation platform marks the invoice paid and reconciles it against the bank feed.
