For agencies, developers, and vibe coders

Ship client sites without building a backend.

Lead forms, content your client edits in a Google Sheet, document uploads that land in their Drive, online payments, and service-area maps — all working on the first site you connect, and every one after it. No server to stand up, no CMS to license, nothing new to maintain when the project ships.

Google Sheets · the inbox · Google Drive · Stripe · on-brand maps — one connection per client site

every one of these runs through s7a
Five services

What your client sites get.

Each service replaces a backend you would otherwise build, host, and babysit per project. Point the site at s7a and the outcome is just there.

Sheet CMS

Your client edits a Google Sheet. Their site updates itself.

No CMS logins, no training calls. Per-tab resilience and a fallback ladder keep the site up even when the sheet breaks, health alerts tell you before the client notices, and an edit-to-revalidate webhook makes changes show up on their own.

Works with Google Sheets

Leads

Every form submission lands in the inbox and the Sheet. Spam never does.

Honeypot filtering and rate limits are built in, BCC keeps whoever needs a copy in the loop, and a staging-to-production flip means you test the whole pipeline before a single real lead flows.

Delivers to the inbox + Google Sheets

Intake

Client documents go straight into the client’s own Google Drive.

Uploads land in their Drive, organized by session — not on your servers, not in your inbox, never forwarded by hand. No middleman storage means no liability sitting in your stack.

Files into Google Drive

Billpay

Patients pay their balance online.

For healthcare providers (DME/HME): NikoHealth-integrated bill lookup plus Stripe payment, on the provider’s own site. Balances get found and paid without a phone call or a mailed statement.

Runs on Stripe + NikoHealth

Maps

A service-area map that matches the brand.

Clean SVG coverage maps rendered from the API — styled to the site, not to Google. No Google Maps iframe, no embed widgets, no per-load map fees on a page that exists to convert.

Rendered as on-brand SVG

Wire it once per client site. The next build starts at the design, not at the form handler, the CMS, or the uploads bucket.

The gateway

Safe to hand to a client site.

Every client site gets its own key, bound to its own domain. Usage is visible per domain and any key dies in one click — so a key leaking out of a client build is an inconvenience, not an incident.

Keys bound to the client’s domain

Browser pk_ keys only work from the domains you register for that client. Copied off their site, the key returns 403 — not your data. Server sk_ keys never leave the server.

Client secrets in an encrypted vault

Sheets, Stripe, NikoHealth credentials live in a write-only vault, encrypted with AES-256-GCM. Stored once, read by services, never returned to a browser or a dashboard again.

See usage per domain. Revoke in one click.

The dashboard shows exactly which client site is making which requests. If anything looks wrong, kill that key from the dashboard and it dies on the next request — without touching any other client.
