Project: WordPress marketplace theme customization (RFQ workflow) Description: We are using a WordPress freelance theme and need a logic-focused customization (not a full redesign). Scope of work: Rework the project / tender creation workflow into a step-based process. Step 1: Create lot item positions (min 1, max 25 per tender). Each position includes: Manufacturer (autocomplete, ~50 predefined + free text), Equipment model (text), Serial number (optional), Part number (optional), Part description (short title, max 20 chars), Quantity (default unit: pcs). Step 2: Project-level options (keep existing ones) + add mandatory checkboxes for Terms & Conditions (AGB) and Export control / sanctions compliance. Implement Incoterms-based delivery logic (EXW, FCA, FOB, CIF, CPT, CIP, DAP, DDP) with dynamic destination fields (no maps, no regions, country + city only where required). Rename “Budget” to Target price, make it optional, reference-only (no price filtering). Add an Accepted condition block (multi-select: New OEM, New Equivalent, Repair / alternative). Keep Description and Attachments logic unchanged. Update Preview step to show all new data in a compact, readable summary. Final step: one-click Finalize & redirect (no extra confirmation screen). Assign a unique tender ID on finalization. Important notes: Remove legacy fields (Categories, Skills, old Location) from forms, display, and filters. In search/listings, only Manufacturer should be indexed from item positions. UI/visual fine-tuning is out of scope for this phase (logic first). Work must be done via child theme (no core theme edits). Deliverables: Fully working tender creation flow Updated preview and project card data handling Clean, maintainable PHP/JS implementation
