Invoices and Receipts for Content Agencies

Content agencies bill monthly retainers, article packages and one-off campaign pieces, often for several clients at once. Clear invoices separate the retainer from anything extra so clients approve them quickly. Receipt Caker builds each document in your browser with totals that calculate themselves.

How do content agencies invoice clients?
Receipt Caker lets content agencies build itemized invoices in the browser with no signup. Add your agency details, list the monthly retainer, article packages or extra pieces, and the subtotal, tax and total calculate automatically. A live preview shows the finished invoice as you work, then you export a free PNG or a watermark-free PDF with your own logo and send it to the client from your own account.

Retainers as the baseline

Most content agencies run on monthly retainers. Each month you issue a fresh invoice for that agreed package, keeping the record clean and predictable for the client.

Stating what the retainer includes, such as four articles and eight social posts, on the invoice reminds the client of the value they receive each cycle.

Receipt Caker does not send invoices on a schedule, so you control when each month goes out and reuse the same structure to keep it fast.

Handling work beyond the retainer

Clients often ask for extra pieces mid-month. Charging these as separate lines, or a separate invoice, keeps the retainer clean and the extra work clearly accounted for.

A short description on each additional line, such as launch announcement article, explains the charge and prevents it looking like scope creep.

The totals recalculate as you add lines, so a busy month with several extras still adds up correctly.

Consistency across a client roster

With many clients on retainers, a consistent invoice format saves time and makes your records easy to search. Every document follows the same clean layout.

Receipt Caker renders each invoice on your own device, so your full client list and pricing never sit on a third-party server.

Export a PDF for anything you want to archive, keeping a tidy monthly folder of everything the agency has billed.

Frequently asked questions

How do I bill a monthly retainer plus extra pieces?
Put the retainer on its own line with the agreed monthly amount and a short description of what it includes, such as monthly content retainer, four articles and eight social posts. Then add a separate line for each extra piece the client requested that month, with its own description and rate. Receipt Caker adds everything into the subtotal, applies tax and shows a grand total, so the retainer and the extras are clearly distinguished on one document. This structure reassures the client that they are paying the agreed retainer plus only the additional work they specifically asked for. If you prefer, you can even issue the extras on a second invoice to keep the retainer figure identical every month, which some agencies find makes their records easier to reconcile at year end.
Does Receipt Caker send retainer invoices automatically each month?
No. Receipt Caker is a document generator, not a billing system, so it does not send invoices on a schedule or run recurring billing. Each month you open the tool and create the retainer invoice yourself. This is quick in practice: reuse the same line structure from the previous month, update the billing period and any figures, and the totals recalculate as you go. You then export a PNG or a watermark-free PDF and send it to the client from your own email. Many agencies prefer this because it keeps them in full control of timing and lets them add any extra pieces before the invoice goes out. Since all rendering happens client-side, your client roster and pricing stay on your own device rather than on a third-party server.
What should a content agency invoice include?
A content agency invoice should include your agency name and contact details, the client name, an invoice number, the issue date, the billing period and payment terms. In the body, list the retainer and any additional pieces as separate lines with clear descriptions, quantities and rates so the client can follow each figure. Add a subtotal, any tax, a clear grand total and your payment instructions. Receipt Caker prompts for each field and calculates the totals automatically while showing a live preview, so you can confirm client names and figures before sending. Once the invoice looks right, export a free PNG for a quick send or a watermark-free PDF with your logo for your archive, then send it to the client from your own account.
