Chapter 1 — What This Guide Is For
You're a B2B buyer. This guide walks you through ordering products from your supplier's online catalog. Browse, add to cart, check out — same as any e-commerce site, just for business orders.
Quick context
Your supplier (the warehouse / 3PL operator) has set up a catalog of products you can order. The portal works like a B2B online store:
- Browse products with prices.
- Add what you want to your cart.
- Pick a delivery address.
- Submit the order.
- Track it.
- Pay the invoice.
You won't see any of the warehouse's internal workflow. That's all on their side.
Chapter 2 — Logging In For the First Time
Before you start
- You've received an invite email from your supplier.
- The portal URL is in the email — looks like
www.trenvar.com/yoursupplier/login. - Use a current browser (Chrome, Edge, Firefox, Safari).
Walkthrough
- Open the invite email. Click Accept invitation.
- Pick a password — at least 12 characters with letters, numbers, and symbols. Type it twice. Click Set password & continue.
- You're sent to the login page. Enter your email and password. Click Sign In.
- You land on the catalog — your home screen as a B2B buyer.
If the email never arrives
Check spam. Still missing? Email info@trenvar.com or contact your supplier.
Chapter 3 — Finding Your Way Around
The screen layout
- Top bar — your supplier's logo on the left. On the right: search, your cart icon (with a count badge if you have items), your initials. Click your initials for Profile, Sign out.
- Sidebar (left) — Catalog (default), Orders, Invoices.
- Main area — whatever you clicked. Catalog shows products as a grid; Orders and Invoices show lists.
How the catalog works
The catalog is filtered to what your supplier has made available to you. You won't see products outside what they've set up. Prices may be your specific contracted prices (if your supplier has set custom prices for your account), or the public catalog price.
Chapter 4 — Browsing the Catalog
Walkthrough
- Click Catalog in the sidebar (or it's your home screen by default).
- Browse the product grid. Each card shows: product image (if available), name, price, stock indicator ("In stock" / "Out of stock"), estimated lead time.
- Use the search bar at the top to find specific products by name or SKU.
- Use the category filter on the left to narrow down.
- Click any product card to see detail: full description, dimensions, full price, available quantity, minimum order quantity (if any).
What "Available" means
Each product shows a stock indicator:
- In stock — ready to ship. The number shown is current available quantity.
- Limited stock — running low. You may want to order soon.
- Out of stock — none available right now. The product card is greyed out; you can't add it to cart.
Why is a product missing?
Either it's out of stock, or your supplier hasn't made it available to your account. If you expect a product to be there and it's not, message your supplier.
Chapter 5 — Adding Items to Your Cart
Walkthrough
- Click on a product card to open detail.
- Type the quantity you want (must be at least the minimum order quantity if one is set).
- Click Add to Cart.
- A small toast confirms: "Added — N × [Product Name]". The cart icon at the top right shows a count badge.
- Keep browsing or click the cart icon to review.
Reviewing your cart
- Click the cart icon (top right).
- The cart page shows every item: product, quantity, unit price, line total.
- Edit quantities directly in the cart, or click the trash icon to remove a line.
- The total updates automatically.
- When you're ready, click Proceed to Checkout.
Save your cart for later
Items you add to your cart stay there until you check out — even if you sign out and come back later. Useful for building up an order over a few days.
Chapter 6 — Checking Out — Placing the Order
Walkthrough
- From your cart, click Proceed to Checkout.
- Fill the checkout form:
- Ship-To Address — your default delivery address is pre-filled. Click Edit to change it or pick another saved address.

- Estimated shipping.
- Estimated tax.

What happens after

- You see all your orders with status pills.
- Click any order for detail:

Chapter 9 — Common Problems and How to Fix Them
"I can't sign in"
- Try password reset: on the login page click Forgot password?, enter your email, follow the link.
- Still stuck? Email info@trenvar.com.
"A product I want isn't in the catalog"
- Either out of stock, or your supplier hasn't made it available to your account.
- Message your supplier — they can add it.
"My cart says 'quantity exceeds available'"
- The supplier doesn't have enough stock right now. Reduce the quantity, or wait and check back.
- Message your supplier if you need a larger quantity restocked.
"I can't add to cart — minimum order quantity"
Some products have a minimum order quantity (e.g., must order at least 10). The minimum is shown on the product detail page. Increase your quantity to at least the minimum.
"My order is stuck at 'open'"
The supplier hasn't started picking yet. Most pick same-day; during peak times it can take longer. Contact your supplier if it's been more than 24 hours.
"The price seems wrong"
- Your contracted prices may differ from public prices. Check the supplier's contract or ask them.
- If you suspect a mistake, take a screenshot and message your supplier.
"I created the wrong order"
- Open the order. If status is still open, click Cancel.
- If picking has started, contact the supplier fast — they may be able to stop it.
Chapter 10 — Getting Help
Inside the portal
- The Orders and Invoices tabs are the fastest reference for "what did I do?"
- Hover over any field's ? icon for inline help.
Outside the portal
- Your supplier — for product availability, pricing, order changes, billing. They have full visibility into your activity.
- Trenvar support — for platform issues that aren't account-specific.
- Carrier websites — for tracking after dispatch.
