Polite Retainer.

Polite Retainer · $19/mo

Hours bank. Month-end invoice.

A browser kit for freelancers with a retainer: included hours, used, remaining — then a month-end invoice with your own pay link. Print or PDF. Thinner than a portal.

Get Polite Retainer — $19/mo Open the kit How it works

Polar is merchant of record for the kit. Client invoice pay uses YOUR_CLIENT_PAY_LINK — your Stripe, PayPal, or ACH. Not a portal. Not collections.

What it is

Track the bank. Invoice the month.

01

Hours bank

Included, used, remaining, period, rate. One sheet the client can read. Firm. Short. Adult.

02

Month-end invoice

Line items from used hours plus optional extras. Total and due date. Print or Save as PDF.

03

Your pay link

A button: “Pay invoice — $X.” Href is your own checkout — YOUR_CLIENT_PAY_LINK. Polar sells the kit only ($19/mo).

Who it is for

People who sell hours, not portals.

Freelancers and tiny studios with a monthly retainer or hours bank who need a clear remaining-hours page and a clean month-end invoice — without another SaaS login wall.

Hard edges

  • Not a portal. No multi-project dashboard, no messaging, no SaaS app.
  • Not collections. No late-notice chase, no day 1–7–14 pack.
  • Not legal advice. Not an MSA, not a demand letter.
  • Not Polar for client pay. Invoice button is your Stripe / PayPal / ACH.

How it works

Fill the bank. Switch to invoice. Print.

  1. Open the kit.

    Browser-only page. Northline Studio → Harbor & Birch, 10 hr/mo @ $150, 7 used, loads so you are not staring at empty fields.

  2. Edit hours, extras, due date, pay link.

    Hours bank and invoice views update live. Paste YOUR_CLIENT_PAY_LINK — your own checkout URL.

  3. Print / PDF and send.

    US Letter. Editor chrome hides. Buy the kit for $19/month on Polar — use the Get Polite Retainer buttons (https://buy.polar.sh/polar_cl_1Zq15tbq87XESKvAYKKkgwOsRtdrpE2Db0xxe471OJS).

Privacy

Retainer data stays in the browser.

No Retainer backend. No API key. Edits live in localStorage on the computer you opened. Clearing site data deletes them. Keep the PDFs you print. Polar is only how you buy Polite Retainer from Trutara ($19/mo) — not a client billing host.

Tone

Firm, short, adult.

States the bank, the used hours, and the amount due. Does not sell. Does not apologize. Does not threaten.
