Technicians open work orders, pull truck stock, and log hours in concrete mechanical rooms with zero cell signal. Field updates save locally on the phone and sync to the office once when signal returns—and every part pulled off a truck goes onto the job at the actual price you paid for it.

Every purchase receipt, van transfer, stock count, and labor hour ties directly to the work order it belongs to and the person who recorded it.

A spreadsheet loses the thread between a stock count, a work order, and a supplier cost. Korblok holds the three together across service calls and multi-week retrofits, so margin variance is a number you can act on before the job closes.
| Job | Work | Estimate | Actual | Variance |
|---|---|---|---|---|
| WO-4471 | Rooftop unit replacement | $18,400 | $17,960 | +$440 2.4% |

Whether a crew is running two-hour service calls in the morning or a six-month commercial retrofit in the afternoon, work orders, truck stock, job costing, and audit history stay on one connected record.
Materials, labor, subcontract, and overhead roll up to the job as the work happens, against the estimate on the work order. Margin is visible while the job is open and after it bills, and when a job runs over, the breakdown shows which category moved before closeout.
Track stock across the warehouse, aisle, bin, and individual service van. Counts reconcile against purchase receipts and job usage in the order stock arrived, so missing parts point to a specific job or transfer instead of guesswork.
Dispatch same-day service calls and track multi-week commercial jobs on the same schedule. Preventive maintenance and recurring service generate automatically on the cycle you set.
Every technician, apprentice, dispatcher, and bookkeeper gets their own login—no shared accounts that destroy accountability. Every change records who made it, when, and against which job.
Eight operational questions to ask any software vendor before you switch.
| Topic | Ask any vendor | Korblok |
|---|---|---|
| Getting started | Does onboarding require months of paid consultant hours? | Import your existing customer, item, and equipment spreadsheets directly—no consultant required. |
| Work with no signal | What happens when a technician is in a basement with zero cell signal? | Assigned work orders open offline. Hours, parts, and notes save on the phone and sync to the office once. |
| Cost of a part | Does each part drawn off a truck carry the exact cost it arrived at? | Parts go onto the job at the actual price paid for that batch, in the order stock arrived. |
| Van stock | Does the system track inventory down to each individual service van and bin? | Every warehouse aisle, shelf, and service van is a tracked stock location. |
| Team logins | Do per-user seat fees force your technicians to share logins? | Every technician, apprentice, dispatcher, and bookkeeper gets their own verified login and audit trail. |
| Supplier increase | Can a supply-house price increase update your price sheet on a scheduled date? | Flag items whose cost rose, select the affected parts, and schedule a percentage raise across all tiers. |
| Data ownership | Can you export your full operational history without paying a release fee? | Your jobs, customer history, attachments, and cost records export cleanly at any time with zero exit fees. |
| Card payments | Are you forced to run payments through the software vendor's marked-up processor? | Reconcile checks and ACH straight from your bank export. Korblok takes 0% of your payments. |
Costs attach to the work order as they are incurred. Nothing waits for a month-end close, and nothing gets allocated by guesswork. When a job runs over estimate, the rollup shows immediately which category moved.
When a van count does not reconcile, or a commercial client disputes an invoice line, the record has to stand on its own. Korblok keeps the chain from purchase order to the work order that consumed the part, with the exact quantity and purchase cost at every step.
Getting started should not require a nine-month implementation or paid consultant hours. The import path takes the spreadsheets you already keep and maps them once.
Import customers, items, and site equipment straight from the spreadsheets you already maintain.
Match your columns once and preview every row to catch formatting mistakes before finalizing the import.
Open work orders against live warehouse and van stock. From the first job, materials and labor land where they belong.
Predictable monthly tiers with unlimited user logins. Add every technician, apprentice, dispatcher, and bookkeeper with zero per-seat fees.
Full operational history, photos, and job-cost exports are built into every account with zero release or exit fees.
