Piloxa Rule: Bill Certified Mail as a Pass-Through Line Item, Not Retainer Work

Should an agency adopt Piloxa as a billable service line, and which client engagements justify wiring it into delivery? Adopt Piloxa only when the client's certified-mail volume and per-notice billing model let you pass the $12.97 to $24.21 per-letter cost through with a margin, and skip it when you need subscription MRR from the engagement.

“Should an agency adopt Piloxa as a billable service line, and which client engagements justify wiring it into delivery?”

Adopt Piloxa only when the client's certified-mail volume and per-notice billing model let you pass the $12.97 to $24.21 per-letter cost through with a margin, and skip it when you need subscription MRR from the engagement.

Common Mistake

Agencies pitch Piloxa as a monthly managed service and then discover there is no subscription tier to anchor a retainer against, leaving them to invoice per letter while carrying the setup cost (about 16 hours) and the human review checkpoint on every send. The fix is to price the engagement as per-notice pass-through plus a fixed setup fee, not as recurring MRR.

Why This Works

Piloxa charges per mailing with no subscription or account fees, so there is no recurring platform revenue for the agency to resell; the Certified Mail tier at $12.97 and the Evidence Pack at $24.21 are one-time costs that must be marked up or billed back to the client. The verdict is explicit that this model suits agencies billing clients per notice rather than seeking recurring retainer revenue, and that resale potential exists in property management, legal support, and compliance-heavy verticals. The MCP connector and OpenAPI require no key, OAuth, or account to connect, which lowers integration friction but does not change the transactional economics.

Apply When
  • •The client sends at least 20 certified notices per month (demand letters, lease terminations, compliance correspondence) where a $12.97 Certified Mail send or a $15.97 Certified Mail + Electronic Return Receipt send is cheaper than staff time spent at the post office.
  • •The engagement is transactional by nature: property management, legal support, or compliance-heavy verticals where the client already pays per notice rather than a flat monthly fee.
  • •The agency already runs an AI agent or document workflow (Claude, ChatGPT, Gemini, or an internal tool) that can pass a finished letter as text or PDF bytes into the Piloxa MCP connector at https://piloxa.com/mcp or the OpenAPI description at https://piloxa.com/openapi.json.
  • •The client needs an auditable record: Piloxa returns the approved document with its SHA-256 fingerprint, the mailing record, and USPS tracking scans, retained for 1 year.
  • •The agency can absorb a medium-complexity setup (roughly 16 hours for a first workflow) before the first live letter goes out.
