Admin add-ons rarely look exciting and often pay back fastest. Look for the job your team repeats every week.
| Weekly job | Add-on | Result |
|---|---|---|
| Changing prices and stock | Spreadsheet Bulk Product Editor | Spreadsheet grid with preview, change log and undo |
| Supplier updates | Scheduled Supplier Feed Import | CSV, XML and JSON feeds from URL, FTP or SFTP on a schedule, with price rules |
| Moving categories | Category Import & Export | Category tree as CSV with paths, SEO names and images |
| Finding catalog gaps | Catalog Quality Audit | Missing images, prices, features, SEO, duplicates |
| Working through orders | Orders Admin Pro | Your columns, SKU and phone search, tags, notes, bulk actions |
| Reordering stock | Purchase Orders & Suppliers | Reorder suggestions, purchase orders, partial receiving |
| Issuing documents | Invoices & Credit Notes, EU e-Invoicing | Gapless numbers, credit notes, EN 16931 e-invoices |
Paid channels only work as well as the data you send them. Product Feed Pro for Google Merchant Center builds Google Shopping feeds per country, currency and language, with category mapping, variants, custom labels and a validation report. Multichannel Product Feeds covers Meta, TikTok, Pinterest, Microsoft Shopping, Snapchat, Criteo, idealo and custom files.
Browser tags miss sales when blockers or consent choices get in the way, so add server-side events. Ecommerce Tracking Pro sends GA4 ecommerce events with Consent Mode v2, plus server-side purchases and refunds. Server-Side Tracking for Meta pairs the Pixel with the Conversions API using shared event IDs. Marketing Pixels Pack adds seven more ad platforms.
Revenue tells you little if margin varies by product. Product Cost & Profit Reports stores cost prices and reports gross profit per order, product, category and period. Sales Reports Pro adds comparison, product funnels, RFM segments, cohorts and customer lifetime value.
For accountability, Admin Activity Log & Audit Trail records who changed what with before and after values, and Email Log & Background Sending logs every e-mail with its SMTP status, which helps with "I never got the e-mail" tickets. Telegram & WhatsApp Order Notifications tells staff and vendors about orders where they already are.
| Job | Best tool |
|---|---|
| Change 500 prices once | Bulk Product Editor |
| Take a supplier price list every night | Scheduled Supplier Feed Import |
| First import of a new catalog | Core product import |
| Move a category tree between stores | Category Import & Export |
| Send products to Google or Meta | Product Feed Pro, Multichannel Product Feeds |
A rule of thumb: if a person decides the change, use the editor. If a file decides it, schedule an import. Either way, keep a database backup before the first large run.
Order teams gain most from Orders Admin Pro, which also works for vendors. Both the order list and the customer panel show what would otherwise take several clicks: past orders, refund rate, tags and notes.
