Pricing

Business/Profile app access is bundled across SaaS web, iOS, and Android after a two-week free trial. Letter execution remains quote-before-send: the number you see at the quote step is the number you pay. VAT included where applicable.

Pick the pricing path for your motion

SMB app users: start the Business/Profile bundle trial. API/agent buyers: quote letters through API, MCP, GPT Actions, SDKs, x402, or UCAN. Legal/Clio buyers: use the Clio/Royal Mail path. Switcher buyers: upload a Stamps.com, franking, or postage-meter invoice when the switcher flow opens and qualify for configurable rewards such as 200 PostBridge points.

Public/private offer matrix

The public price list stays quote-before-send. Private packaging gives qualified API, legal, and enterprise buyers a predictable monthly platform commitment layered on top of per-letter execution.

Questions you might have

Is there a free tier?

Installing PostBridge is free — on Clio, ChatGPT, or via API key. You're only charged when you send a letter.

Do prices change?

Postage rates are set by the national carrier (Royal Mail, USPS, etc.) and can shift annually. When they do, we update this page and the quote engine in lockstep. The price you see at the quote step is always the price you pay for that letter.

What about volume pricing?

For firms or platforms sending 500+ letters per month, contact nora@agents.postbridge.ai for volume terms.

Can I get a VAT invoice?

Yes — Stripe receipts include VAT line items for UK destinations. For consolidated monthly invoicing, email ops@agents.postbridge.ai.
