SUBLAKE runs the front office 24/7 for field and home service businesses — an AI Receptionist that answers every call, text and web chat and takes the job down, flagging urgent ones to your phone, and an AI Office Manager that handles reminders, confirmations and no-show follow-up. It includes online booking, payments, a unified contact record and analytics.

How much does SUBLAKE cost?

SUBLAKE has two plans, and both include the full AI Front Office — online booking, payments, and a unified customer record. Pro is $99/month with 300 voice minutes, 1,000 texts, 1,000 emails, 5,000 contacts and 3 team seats. Business is $299/month for busier shops: 1,000 voice minutes, 5,000 texts, 5,000 emails, unlimited contacts and seats, and priority support. Both have hard caps — never overage. Every account starts with a 14-day free trial — no credit card required.

What does the AI actually do?

The AI Receptionist answers every inbound call, text and web chat 24/7, answers questions about your services and prices, takes the job down — who, where, what is wrong and when suits them — and pushes urgent jobs to your phone. It never books a time itself: you call back and confirm it, or customers book themselves through your booking link. The AI Office Manager then sends the confirmation and reminders and follows up after a no-show.

Which industries is SUBLAKE built for?

SUBLAKE is built for field, home and commercial service businesses: plumbing, HVAC, electrical, roofing, landscaping, cleaning, pest control, appliance repair and the other trades where you are on a job and cannot pick up the phone.

Is there a free trial?

Yes. SUBLAKE includes a 14-day free trial on every account. No credit card is required to start, and you can cancel before day fifteen for $0.

Developers: API & API keys

SUBLAKE has a REST API for your own software, signed webhooks for everything that happens, and an MCP server for AI assistants. Everything is in Settings → Developers (business owner only).

Base URL

https://backend.sublake.com/api/public/v1

The full description is at https://backend.sublake.com/api/public/v1/openapi.json (OpenAPI 3.1 — import it into Postman or any client generator).

API keys

Create a key in Settings → Developers → API keys: name it and choose what it may do (its scopes). The key (sk_live_…) is shown once — store it in a secret manager. You can roll a key (the old one keeps working for the time you choose, so nothing breaks while you swap it) or revoke it at once.

curl https://backend.sublake.com/api/public/v1/me \
  -H "Authorization: Bearer sk_live_…"

GET /me answers your business's name and the key's scopes.

Scopes

customers:read — see your customers · customers:write — add and update them
requests:read — see your requests · requests:write — add requests
quotes:read, jobs:read, visits:read, invoices:read, payments:read — see those records
webhooks — be told when something happens

What you can read and write

GET /customers, /requests, /quotes, /jobs, /visits, /invoices, /payments — a page of records, newest first — and GET /<records>/{id} for one
GET /customers/find?email=… or ?phone=… — the customer with that email or phone
POST /customers — add a customer (refused, naming the existing one, when the email or phone is already on file) · PATCH /customers/{id} — change one
POST /requests — file a request for work, numbered and marked as made by your app
GET /events — what happened, read after the fact (Webhooks)

Money is in integer cents and times are ISO 8601 UTC.

Paging and filters

Lists take limit (1–100, default 25) and starting_after (the id of the last record you have), and answer has_more and next_starting_after. Most lists filter by created_after, created_before, updated_after, and by their customer, job or status — the OpenAPI description lists each one.

Retrying writes safely

Send an Idempotency-Key header with any write. Sent again within 24 hours with the same key, the first answer is given again and nothing is done twice.

Errors and limits

Errors are JSON: {"error": {"type", "code", "message", "param"}}, with an HTTP status that matches the type (400, 401, 403, 404, 409, 429). Every answer carries RateLimit-Policy and RateLimit headers; past the limit you get 429 with Retry-After.

Apps that act for other businesses (OAuth)

An app used by many SUBLAKE businesses signs each one in with OAuth 2.1: authorization code with PKCE (S256), at https://backend.sublake.com/oauth/authorize and /oauth/token, with discovery at /.well-known/oauth-authorization-server and client registration at /oauth/register. The owner sees your app's name and exactly what it asks for, and can disconnect it any time.
