WHMCS Installation & Core Setup

Job ID: 39632236

Budget: $30 – $250 USD

Scope of Work

WHMCS Installation & Core Setup

Optimise cron, security settings, email templates, language packs.

Configure products / addons that map 1‑to‑1 to our software licences.

Licence‑Server Integration

Activate and fine‑tune the WHMCS Licensing Addon (or a custom module if you prefer).

Expose the verification endpoint (callback / check‑in) and embed the licence check in our app (curl / Guzzle, whichever is cleaner).

Implement graceful fail‑over logic (e.g. cached token, retry, lockout light).

Payment Gateway Configuration

Hook up Stripe + PayPal (SCA‑ready) in the WHMCS client portal.

End‑to‑end test: order → invoice → payment → licence auto‑provisioning.

Optional: EU VAT handling & webhooks for refunds/cancellations.

Single‑Sign‑On (nice‑to‑have)

If time allows: implement OAuth2 / JWT SSO between our main site and the WHMCS client area so users don’t juggle two logins.
