Why glass shops switch
Why Glass & Window Companies Choose Claver
Residential glass is a same-day, cash-flow business with brutal competition. The big chains have the brand recognition. The independent shops that win compete on speed (same-day dispatch with the right IGU in the truck) and on the upsells the chains miss (the custom shower glass installation that requires precise measuring and hardware compatibility).
The shops that win two things differently: they dispatch with the correct IGU already in the truck (so the call doesn't become a two-trip job), and they capture the custom glass revenue that 30% of competitors forget to quote for.
Correct IGU truck stock is the engine. Custom glass installation is the missed revenue.
When the 9:14am storm-damaged window call hits, your dispatch board pulls the specs from the customer's intake (24x36 double-hung, 28mm spacer) and identifies the correct IGU (Pilkington with argon fill and warm-edge spacer). Claver checks truck stock. David has 3 of this IGU in his van. Closest tech, right IGU, all the vacuum lifters loaded. Customer gets an automatic text: "David's on his way. ETA 38 minutes. Bringing your correct IGU and lifters. Total estimated $450 (IGU and labor), due at completion." The customer stops worrying about the chain's 5pm appointment slot.
Direct billing is what makes the customer's quick payment experience work. Claver pulls the customer's quote info during intake (scope, dimensions, labor). Files the job through Claver's job management or directly with the homeowner. Generates the invoice (materials, labor, disposal fees). Bills the homeowner directly. Customer pays her $450 via link at job completion. You collect the $450 in 2 days, not 60. Your A/R aging on residential work drops from 47 days to 2.
Custom shower glass installation is the upsell that separates the independent shops from the chains. Every shower door requires precise measuring (width and height to 1/16 inch) and hardware compatibility (frameless vs semi-frameless). The manufacturers require it. The homeowners pay for it. But 30% of competing shops skip it (or don't know to charge for it). Claver flags the requirement based on the job specs and dimensions, schedules the custom fabrication (3-10 day lead time), and adds the $800 line item to the invoice. That's $115/job in additional revenue you're now capturing, and the customer's shower door actually fits after the install.
Per-job material history is what catches the next repair before it fails. 2018 Kitchen Window, dimensions 24x36, IGU replacement March 2024 (Pilkington with argon, $450), prior seal failure November 2023 ($120 patch), customer preferences (mobile service at home, prefers Saturday morning). When she calls back in 2026 about a new crack on the highway, your tech pulls up the job and sees the IGU is 18 months old (within the warranty), the prior failures, the right IGU part to order if this one cracks. Honest conversation, fast service, repeat customer.
And mixed-route density is what turns the window-only Tuesday into a higher-revenue mixed Tuesday. Claver groups jobs by zip code regardless of type. Your old Tuesday: 8 window replacements scattered across Charlotte with 90 minutes of cross-town driving — 7.5 hours, $4,680 revenue. Your Claver Tuesday: 8 window replacements + 4 shower glass installs (custom frameless, $1,200 each) + 2 storefront repairs grouped by Dilworth and South End and NoDa with 22 minutes total drive time — 8 hours, $7,485 revenue. Same truck. Same tech. Revenue up 60%.
