Wholesail builds custom B2B ordering portals for plumbing and HVAC supply distributors. Plumbers and HVAC contractors check live inventory by part number, place orders, and schedule will-call or delivery — per-contractor pricing, job site address book, and net-30 billing included. Live in under 2 weeks.
A plumber or HVAC tech without the right part is costing their customer $150+ per hour. They need confirmation fast.
Contractors call before every order to ask if you have the part in stock — and your counter staff spends the first half of every day on availability calls.
Emergency jobs mean contractors need parts immediately, but after-hours phone orders don't reach your team until the morning and the job sits.
Every contractor has negotiated pricing and your counter staff is manually checking rates and fixing invoices after every phone order.
Delivery to job sites requires a phone call to give the address, and addresses have to be re-provided on every single order.
Live inventory by part number and spec is visible in the portal around the clock. Contractors confirm availability in seconds and place the order without a call.
Orders placed after hours queue automatically and are prioritized at first fulfillment. Contractors get confirmation immediately and know their part is coming.
Per-contractor pricing is configured in every account. The rate shown at checkout is the rate on the invoice — no rate checks, no corrections.
Contractors maintain a job site address book in the portal. Selecting a delivery address at checkout takes five seconds.

I was on a rooftop replacing an HVAC unit and realized I needed a specific part. I checked inventory on my phone, saw it was in stock, placed the order, and scheduled a pickup for when I got down. By the time I was back on the ground, the order was being pulled. That would have been a 20-minute phone call before.
