POinbox is Shopify purchase order automation for wholesale and B2B stores that still get orders as attachments. A buyer emails a PDF, Excel sheet, CSV or Word file, and POinbox reads the purchase order, matches the buyer to a Shopify customer, B2B company and company location, and matches each line to your catalog, including the buyer's own item codes. It builds a Shopify draft order at your catalog price, shows any price differences, and keeps lines that are not a confident match off the draft until you confirm them. The PO number is written to Shopify's purchase order field. POinbox handles customer POs coming into your store; it is not a supplier purchase order tool, not EDI and not a wholesale portal. Plans: Free covers 5 successful drafts (lifetime); paid plans start at $29/month.

Intercom is only as useful as the contact record. When a WordPress user changes role or signs up, that rarely reaches Intercom unless someone runs a CSV export, keeps a Zap alive or maintains a custom script. Sync Engine for Intercom keeps the contact current from WordPress. Connect with OAuth or an Intercom Access Token. New and updated users sync with email, name, phone and avatar, and WordPress roles become Intercom tags that change when the role does. Free includes basic user sync, role tags, 4 events (User Registered, Login, Logout, Profile Updated) and email support. Pro adds WooCommerce events, attribute mapping, bulk sync and priority support. WooCommerce features are Pro only. Sync runs in the background on your own site. It is not a chat widget, and Messenger stays optional. Free: $0 forever. Pro: $99/year.

Integration for Airtable is a WordPress plugin that moves data between WordPress and Airtable. Form submissions from WPForms, Gravity Forms, Contact Form 7, Ninja Forms, Fluent Forms, Formidable Forms and Elementor Pro Forms create records in the Airtable base and table you choose, with visual field mapping. In the other direction, Airtable records import as WordPress posts, pages, users, categories and tags, optionally scoped by an Airtable view or formula. Re-imports update the same item instead of creating duplicates, and a Sync History log shows successes and errors. It connects to Airtable with OAuth. The free plan covers one form connection, 300 form submissions synced and 300 records imported per month. Pro is $99/year and adds unlimited volume, custom post types, ACF fields, media and syncing as often as every 15 minutes. Not an Airtable product.

Content Publisher for Confluence keeps Confluence as the place you write and WordPress as the place people read. Pick a Confluence space and the pages you want, and each one becomes a WordPress page or post with parent/child order, internal links, images and attachments kept. Import as draft or private first, check it, then publish. After the next edit, Sync Now pulls the changes and skips unchanged pages. A shortcode can embed a single page inside an existing post. Readers see your theme and your URL, with no Atlassian account needed. It connects to Confluence with OAuth. The free plan covers up to 10 pages in 1 space, manual Sync Now and shortcode embed. Pro is $99/year and adds unlimited pages, multiple spaces, scheduled sync and role-based reader access. Not an Atlassian product.

SquareFloww is a Shopify app that connects Shopify and Square, which don't integrate on their own. It is a Shopify Square integration for retailers who sell online with Shopify and in store with Square POS. It syncs products and variants (title, description, price, image, SKU), inventory levels by location using Shopify-to-Square location pairs, and customers (name, email, phone), in the direction you choose. It does not sync orders. It suits small and mid-size shops that take payment on Square and sell the same products on Shopify. Plans: Starter $19/month (1,000 products, 500 customers, 1 location pair, manual sync); Growth $39/month (2,000 products, 2,000 customers, 3 location pairs, automatic sync); Pro $79/month (up to 10,000 products and customers, unlimited location pairs, automatic sync). Every plan includes a 7-day free trial. Installs from the Shopify App Store.
