WooCommerce Wholesale & Make an Offer

A custom WordPress/WooCommerce plugin that adds:

1. Role-based registration — a styled front-end login/registration page with a Customer / Wholesale Customer dropdown. Retail accounts activate instantly; wholesale accounts are held for admin approval.
2. Role-based pricing — approved wholesale customers see a separate wholesale price per product (and per variation).
3. "Make an Offer" negotiation — approved wholesale customers propose a price on a product; the admin can accept / counter / reject, and the customer can accept / reject / counter back (bounded rounds). Accepted prices are applied securely at checkout.
4. Admin dashboard — pending approvals and an offers list table (sortable, filterable by status).
5. Live color customizer — change the plugin's brand colors from the settings screen; nothing is hard-coded.

Installation

1. Copy the wc-wholesale-offers folder into wp-content/plugins/.
2. In Plugins, activate WooCommerce Wholesale & Make an Offer (WooCommerce must already be active).
3. On activation the plugin:
   • creates two database tables ({prefix}_wwo_offers, {prefix}_wwo_offer_history),
   • registers the Wholesale Customer role,
   • creates a page named Account Access containing the [wwo_login_register] shortcode,
   • schedules an hourly cron to expire accepted prices.

Pages & shortcode

Put the login/registration form on any page with:

[wwo_login_register]

(The activation step already creates an Account Access page with this shortcode.)

The wholesale "My Offers" tab is added automatically to the WooCommerce My Account area.

Configuration

Wholesale & Offers → Settings

• Brand colors — Primary / Secondary / Light / Accent. Uses the WordPress color picker with a live preview (updates CSS variables instantly); Save to apply site-wide.
• Maximum negotiation rounds — total proposals before only accept/reject remain (default 3).
• Accepted price expiry (hours) — how long an accepted price stays redeemable (default 48; 0 = never).
• Offer rate limit — N offers per time window per customer (default 5 per hour; 0 disables).
• Auto-approve wholesale — skip manual review (off by default).
• Notifications email — where new-offer / approval emails are sent.

Setting a wholesale price: edit a product → Product data → General → Wholesale price. For variable products, set it per variation under each variation's pricing section.

How it works

Registration & approval

• Registering as Customer → role customer, logged in immediately.
• Registering as Wholesale Customer → role wholesale_customer, status pending, shows "Your account is waiting for admin approval."
• Admin approves/rejects under Wholesale & Offers → Approvals. On approval the customer is emailed and wholesale pricing/offers unlock.

Negotiation flow (example)

Wholesale price $10 → customer offers $8 → admin counters $9 → customer accepts → agreed price $9 is applied to that product for that customer at checkout, and expires after 48 hours (one-time use).

Default decisions (as implemented)

Security

• Nonces on every form and AJAX request (wwo_login, wwo_register, wwo_public, wwo_admin).
• Capability checks on all admin/AJAX actions (manage_wwo_offers, wwo_make_offer).
• Server-side validation & sanitisation of all inputs; all output escaped.
• Prepared statements for every custom query; table names built only from $wpdb->prefix.
• ABSPATH guard at the top of every PHP file.
• Rate limiting on offer submissions.
• Pricing is never trusted from the client — the wholesale base price and the agreed price are recomputed/re-validated against the database on every cart recalculation and at checkout.

Template overrides

Copy any file from templates/ to your-theme/wc-wholesale-offers/<file>.php to customise it.

Notes & limitations

• Login page design: the included login/registration layout is a clean, palette-driven baseline. It is built to be fine-tuned to the supplied design image — the markup is in templates/login-register.php and all visuals use the brand CSS variables.
• "Make an Offer" on variable products is tracked at the parent-product level; set a parent-level wholesale price for the best experience. Simple products are fully supported out of the box.
• Real-time updates use AJAX polling (default every 15s) plus email on every status change. The poll interval is filterable via wwo_poll_interval_ms.
• Requires WooCommerce 7.0+, WordPress 6.0+, PHP 7.4+. HPOS-compatible.

Developer hooks (selection)

• wwo_offer_created, wwo_offer_countered ($offer, $actor), wwo_offer_accepted ($offer, $accepted_by), wwo_offer_rejected, wwo_offer_expired
• wwo_wholesale_registered ($user_id, $auto), wwo_wholesale_approved, wwo_wholesale_rejected
• wwo_email_html (filter outgoing email HTML), wwo_poll_interval_ms
