Supplier inventory upload
Read the inventory upload instructions online, then upload by manual file, FTP/SFTP, or email. First files are reviewed before buyer-visible publishing.
Upload options
Read the instructions on this page, then choose the route that fits the supplier: manual upload, FTP/SFTP feed, or email upload. PDF and templates are optional downloads.
Read online first: this page is the live instruction page. The PDF guide is only an optional download for suppliers who want an offline checklist.
Where to upload
verified suppliers use the Supplier inventory upload page after login. The upload page contains the manual file form, upload/download history, supplier instructions, and password/profile links.
Manual stock upload: use the Supplier inventory upload page when you want to send a CSV, XLS, XLSX, XML, JSON, or TXT stock file from the browser. This is suitable for first files, one-off updates, supplier tests, and support uploads by Siemme team members.
FTP/SFTP upload (Recommended)
regular suppliers should ask Siemme to activate a private FTP/SFTP route. This is the recommended route for repeated inventory updates because it supports scheduled refresh, cleaner audit history, and fewer manual mistakes.
Email upload
if portal or FTP/SFTP upload is not convenient, email the file to info@siemme.com with the supplier name, update frequency, source currency, locations, media links, hold terms, return terms, and any special brand/mark notes.
When stock becomes visible: the first supplier file is reviewed and mapped before it appears in buyer search. A clean first file is normally reviewed within one business day during soft launch; missing fields, new column mapping, pricing issues, media gaps, or FTP/SFTP setup can take longer.
Repeat updates: after a supplier format or feed is approved, scheduled FTP/SFTP feeds are checked on the agreed refresh cycle. Configured automated feeds can be checked hourly, but buyer-visible inventory is updated only after validation and live publish are complete.
Upload/download history: suppliers can review their own submissions and download stored source files where available. Siemme team/support users can see recent submissions for testing, supplier support, and audit.
Templates and formats: CSV/XLSX templates remain available as optional downloads. A supplier may also send common market formats; Siemme maps fields where possible and reports missing or inconsistent data.
Quality control
before goods are shown to buyers, Siemme checks certificate numbers, internal stock references, shape, carat, color, clarity, lab, measurements, price per carat, total price, currency, media links, availability, duplicate stones, stale feeds, zero prices, and price math mismatches.
Password and profile settings: registered users can use Profile > Password settings to change/reset password. Sensitive account changes require channel verification.
