Retainer Management & Billing

Q: Can the automation handle different billing rates for different projects?

Yes. The automation pulls project codes and rates from the time tracking system and applies the correct rate to each line item based on the client contract and project assignment.

Q: What if a timesheet is incomplete or missing data?

The automation flags incomplete or missing timesheets and notifies the project manager so corrections can be made before invoicing. Invoices are not generated until all required data is present.

Q: Does the automation work with our existing accounting software?

The automation integrates with mainstream accounting platforms like Xero, QuickBooks Online, and FreshBooks. It syncs invoice data directly, so no manual re-entry is needed.

Q: How does the automation handle client communication?

Invoices are sent automatically to the client contact email address on file, and delivery is logged in the accounting system. Your team can customize the email template and timing.

Keep retainer clients invoiced on time, every month, without the manual reconciliation scramble.

About This Automation

Retainer billing for PR agencies requires collecting timesheets, validating hours against contract caps, and generating invoices monthly. Manual reconciliation between time tracking, retainer terms, and accounting software creates delays, errors, and repeated data entry.

Automation validates timesheets against retainer contracts, flags overages and unused hours, and generates invoices automatically. Invoices are sent the same day billing closes, reducing manual work and catching discrepancies before they reach clients.

Key features:

Validate timesheets against retainer caps and contract terms automatically

Flag overages, unused hours, and billing adjustments in real time

Generate and send invoices directly from validated timesheet data

Sync invoice records to accounting software and CRM without manual entry

Catch data discrepancies before invoices are sent to clients

The issues teams report most often with this process

#	Friction point	Companies Report This
1	Manual data entry across systems Hours are copied from time tracking into spreadsheets and then re-entered into accounting software, creating duplicate work and transcription errors.	80%
2	Retainer cap reconciliation delays Comparing logged hours to contract terms is done manually in spreadsheets, making it slow to identify overages or unused hours.	67%
3	Invoice accuracy review burden Finance staff must manually verify client details, line items, and totals before sending, catching errors that should have been prevented earlier.	53%
4	Billing cycle delays Invoices are sent 2-3 days after the billing period closes because of the time required for manual steps.	40%

How The Automation Works

The full workflow, from trigger to completion.

1. Billing Date Arrivestrigger

The automation runs on the first business day of the month or on the agreed retainer billing date. It pulls the list of active retainer clients and their contract terms.

2. Fetch Timesheet Data

The automation connects and extracts all billable hours logged in the previous month, grouped by client and project.

3. Validate Hours Against Retainer Terms

The automation compares logged hours to each client's retainer cap, contract terms, and any special billing rules. It flags overages, unused hours, and applies adjustments.

4. Hours Valid and Within Terms?

If hours match the retainer agreement, the flow continues to invoice generation. If there are discrepancies or overages, a manual review step is triggered.

5. Create Invoice

The automation generates a new invoice with the correct client, line items, hours, rates, and any adjustments. It sets the invoice date to the billing date.

6. Send Invoice via Email

The automation sends the invoice to the client contact email address and logs the send date and time.

7. Notify Team

A summary message is posted confirming that invoices have been sent, showing client names, amounts, and any flagged items for follow-up.
