Getting paid on time is hard enough without also having to write the follow-up email yourself. This free agency follow-up — retainer invoice template is built specifically for agencies and small studios following up on retainers or project invoices without sounding like a collections agency. Instead of starting from a blank page or reusing a generic payment reminder email that doesn't quite match how late the invoice is, you get a professional-toned, ready-to-send draft matched to this exact stage: overdue. Copy the subject and body as-is, swap in your invoice details, and send it from Gmail, Outlook, or Apple Mail — no account, no signup, and no software to install. It's one of 28 free invoice follow-up templates and payment reminder emails on docstoc, covering everything from a friendly nudge before an invoice is even due through a formal final notice. If you'd rather have the wording generated fresh for your exact invoice, amount, and client, docstoc's AI tool drafts that automatically — this template stays free either way, with or without an account.

FAQ
Is this agency follow-up — retainer invoice template really free?
Yes — every template in docstoc's library is free to view, copy, and edit with no account or signup required. docstoc never emails your clients on your behalf; you copy this draft into your own inbox and send it yourself, so there's nothing to sign up for just to use the wording.
Can I edit the wording to match my own voice?
Absolutely. Copy the subject and body, then adjust the tone, swap in your invoice details, or rewrite any part of it — it's a starting point, not a rigid script. The placeholders like [Client name] and [Invoice #] make it quick to personalize before sending.
When should I actually send this — is "Overdue" the right moment?
This template is written for invoices at the "Overdue" stage specifically. Sending the right tone at the right time matters — too firm too early can feel aggressive, too soft too late can read as not serious. If your situation doesn't quite match, browse the full library for the closest stage.
Does docstoc's AI tool improve on this template?
Yes. This page gives you the wording for free with no signup. docstoc's AI tool goes further on Pro and Business plans — it drafts a version matched to your exact invoice amount, client name, and how many days overdue it is, and can soften, firm up, or shorten a draft on request.
What if the client still doesn't pay after I send this?
If this reminder doesn't get a response, the next step is usually a firmer follow-up or a formal notice, depending on how late the invoice becomes. docstoc's free library includes templates for every stage, from a gentle first nudge through a final notice before collections.
