Produce for restaurants is still a phone-first supply chain. Most guides forget that.

Most independents run a blended model. Broadliners (Sysco, US Foods, Performance Food Group) cover pack produce where consistency matters more than peak flavor: commodity tomatoes, iceberg, potatoes, onions, pre-portioned packs. Specialty produce houses (Baldor on the East Coast, FreshPoint, Greenleaf and Veritable Vegetable on the West Coast, regional players like Paragon, Ratto Bros, Four Seasons) handle heirlooms, local stone fruit, chef-grade herbs, mushrooms, and anything that needs a discerning buyer at 4am at the market. Cash-and-carry (Restaurant Depot, GFS Marketplace) fills same-day gaps. Farmers markets and direct-farm CSAs supply menu-driven kitchens that print a chalkboard. The typical full-service independent uses two to four of these at once.

Because produce is priced and allocated in real time. A specialty house's buyer walks the terminal market at 4am and commits to what's available that morning. By 6am the rep is on the phone with restaurant kitchens offering what's short, what's in, and what the new delivered price is. Portals like Choco, BlueCart, and Xtrachef exist and handle the standing orders well, but the interrupt traffic (substitution calls, weather-driven outages, short-dated deals) still comes by voice because the rep has to hear the chef say 'yes, swap romaine for little gems, I'll take eight cases' in the next 30 seconds. The lead time that forces it onto the phone is also the reason the calls land during service hours.

Four buckets. Availability and substitution ('the strawberries you asked for are 24 dollars a flat today, but I have a beautiful Driscoll half-pint pack for seventeen, want to flex?'). Delivery window changes ('my truck is running 45 minutes late, is that workable or do you want me to drop and go?'). Short-dated or damaged goods that got through receiving ('the case of greens you flagged this morning, I'll credit four pounds, keep the rest?'). And the weekly order-take for operators who still do standing POs by phone. All four are time-sensitive, all four happen during service, and all four fail silently if the call rings out or gets mistaken for a customer order.

On a case-by-case basis, often yes, because you are paying no delivery cost and no rep overhead. But the total cost to the restaurant includes a person driving, a truck wearing down, a labor hour lost from the kitchen, and the risk of arriving to find the exact SKU out. Most operators use cash-and-carry as a gap-fill (forgot to put it on the PO, need two cases tonight, the broadliner already cut the truck) rather than as a primary produce channel. If you run the math across a full week including the owner-hour cost, a specialty produce house that delivers at 6am usually wins on total landed cost for anything you use every day.

For a full-service independent, produce typically runs 5-12 percent of revenue depending on menu (a salad-forward concept runs higher, a red-sauce Italian runs lower). Total food cost for a healthy operator sits at 28-35 percent of revenue, and produce is one of the more volatile pieces because weather and terminal-market pricing swing it week to week. That volatility is why so much of the category is still phone-based: prices move faster than a portal can reprint.

PieLine recognizes that it is not a customer trying to order food. The feature is called Smart call transfer and is defined in the PieLine public site at src/app/page.tsx lines 537 to 540. The AI gathers the context ('I am calling from Greenleaf, we are short a case of little gems for tomorrow, can we swap in butter lettuce?'), writes a conversation summary, and hands the call to whoever you have designated as the operations contact. It does not post the rep's message into Toast, Square, Clover, NCR Aloha, or Revel as a customer cart. The POS round-trip that fires on a customer order (visible in the Denny's demo at 89.12 to 91.52 seconds of public/audio/dennys-order.mp3) is not triggered on a vendor call, because no cart exists.

Not in practice. Standing orders move onto the portal, but real-time events (substitution, weather cancellations, delivery-window shifts, quality credits) still come by voice because those decisions have to be made inside a two-to-three minute window and the rep needs a verbal confirmation. The sensible setup is portal for the baseline PO, phone for the exceptions, and a system like PieLine on the main line so the exceptions do not compete with a customer calling to place a pickup order during the same 30-minute window.

Spend two weeks running them alongside your current supplier, not replacing them. Order five to ten items you know well. Check: are arrivals within the promised delivery window, are case counts honest, are subs communicated before the truck arrives (not on the invoice), is the rep reachable by phone during service, are credit pickups handled without an argument, is the pricing sheet sent weekly without being asked. The rep being reachable by phone during service hours is the one non-negotiable for specialty produce. If they only respond by email and you can only swap things after the truck has already left the yard, they are effectively a broadliner without the broadliner's price leverage.

PieLine is on the phone line. That is a front-of-house and operations problem in most restaurants, but the cost is borne everywhere. When the owner is on the phone with the produce rep at 5:47am and a customer calls to order pickup for 6:30am, somebody loses. When a rep calls mid-service to flag a substitution and the manager does not hear the ring, the substitution hits the invoice and the operator finds out three days later. PieLine takes the 20 simultaneous customer calls off the main line and hands the vendor call to the right human with context. The kitchen feels that as fewer interrupts and fewer surprise subs.

Clone mediar-ai/pieline-phones from GitHub and open src/app/page.tsx. At lines 537 to 540 the feature is defined with the title Smart call transfer and the description: Customer has a complaint or complex catering request? PieLine transfers to your staff with a full summary of the conversation so far. The same behavior is restated in the FAQ at line 959: PieLine uses smart call transfer. If a customer needs to speak to a human, PieLine hands the call to your staff with a full summary of the conversation so far. No context lost.

Open an account with one broadliner and one regional specialty house, and keep a Restaurant Depot membership as backup. Use the broadliner for pack commodities and cold-chain basics. Use the specialty house for anything that sells the menu. Use cash-and-carry for the misses. Do not try to run a farm-to-table direct-source program on day one. The logistics (multiple windows, multiple invoices, multiple credit lines) eat more owner-hours than the menu lift is worth until you have baseline ops dialed.
