# Quarterline

> At quarterline.forevenza.com an Austin restaurant or multi-location operator lists each location's trap type and size, address or area, current pump-out frequency, last pump-out, current hauler, what they pay per service now (optional) and preferred service windows, sees them on a 12-month board against the City's 90-day ceiling, and sends it as a request. The request gets a reference number; a person reviews it, sources service from liquid waste haulers holding a City of Austin permit, and replies by email with a proposed calendar, how one invoice and per-location manifests would work, and a firm price. Nothing is scheduled, ordered or committed until the buyer agrees terms. Contact details are deleted after 180 days.

- [Quarterline: Austin grease trap pumping for restaurant groups, on one 90-day calendar](https://quarterline.forevenza.com/index.md): Put every grease trap your Austin restaurant group runs on one 12-month board against the City's 90-day ceiling, then send it to have every location arranged on one calendar, one invoice and manifests filed per location.
- [Austin grease trap rules, by section number | Quarterline](https://quarterline.forevenza.com/austin-rules/index.md): The City of Austin's grease trap requirements in plain words: the 90-day ceiling and the 50% wetted-height rule (§ 15-10-197), permitted haulers, three years of manifests on site (§ 15-10-165).
- [One calendar, one invoice, manifests per location | Quarterline](https://quarterline.forevenza.com/records/index.md): What an Austin restaurant group asks Quarterline to set up: every location on one calendar, one invoice for the group, and each pump-out's manifest filed against its location for three years.
- [How a Quarterline request works](https://quarterline.forevenza.com/how-requests-work/index.md): From the board you send to a proposed calendar by email: reference number, review by a person, service sourced from City-permitted haulers, nothing committed until you agree terms.

## What you can do

- Send a requirement: POST https://quarterline.forevenza.com/_c/request with the envelope in https://quarterline.forevenza.com/openapi.json (or the MCP tool submit_request). Your board is recorded as a request and given a reference number, shown on screen when you send it. A person reviews the locations, trap sizes, frequencies, last pump-outs, current haulers and service windows you gave, and sources service from liquid waste haulers holding a City of Austin permit. The reply comes by email to the address you leave, with a proposed calendar for all your locations, how one invoice and per-location manifests would work, and a firm price for you to accept or decline. Nothing is scheduled, ordered or committed until you agree terms. Contact details are deleted after 180 days.

- Resume a requirement with request_status using its receipt id and token. Send additional requirements with continuation: {id, token}. Linked authorized offers appear in request_status; inspect_offer, accept_offer, decline_offer and release_payment use the same customer HTTP operations. Keep private credentials for later visits. Payment links lead to the processor; inspect_offer reports verified payment state.
