Retainer clients are the backbone of a stable agency. They're predictable, they compound, and they free you from constantly selling the next project. But too many agencies still bill retainers manually — and a forgotten invoice is forgotten revenue.
Why manual retainer billing costs you money
When you invoice by hand each month, three things happen: invoices go out late, amounts drift, and occasionally one slips through entirely. Late invoices mean late payments, and late payments wreck your cash flow.
What recurring invoicing should do for you
- Generate on a schedule — monthly, quarterly, or annual, without you remembering
- Keep your terms consistent — same line items, same amount, every cycle
- Stay in your control — a draft you review and send, not a surprise charge to your client
How recurring invoices work in BuyerSuite
- Create an invoice and toggle "Make this recurring," then pick a frequency
- Send it and collect payment via Stripe like any other invoice
- Once it's paid, BuyerSuite automatically drafts the next invoice on schedule
- You review the draft and send it — the cycle continues as long as the client keeps paying
Because the next invoice only generates after the current one is paid, a client who lapses simply pauses the series — you're never billing into a void.
Pair retainers with a portal
Recurring invoices are even more powerful inside a client portal, where your retainer client sees ongoing updates, deliverables, and their invoice history in one branded place. It makes the ongoing relationship feel like the premium service it is.
