Run Your Locksmith Business Without Complicated Software

When you’re running a locksmith business, you’re not always sitting behind a desk. You might be answering calls between jobs, scheduling technicians, or finishing invoices after hours.

Cinderblock makes the office work easier, whether you’re a solo locksmith or managing a small crew.

Easy to Learn, Fast to Use

You shouldn’t need weeks of training to check a schedule or send an invoice. Cinderblock keeps the everyday tools simple, so you and your crew can focus on getting jobs done.

Know Where Your Technicians Need to Be

An emergency call comes in while your crew is already booked. Check the calendar, assign a technician, and move appointments when needed. No more guessing who’s available.

Quote Jobs and Invoice Customers on Site

Send an estimate for a master-key installation or invoice an automotive lockout before leaving. List labor, hardware, and service charges separately so the customer knows exactly what they’re paying for.

Remember the Work You Did Last Time

A customer calls about a deadbolt you replaced three months ago. Pull up the job, check your notes and photos, and see what was installed. No digging through old texts or paperwork.

Keep Accounting From Becoming Another Job

Connect Cinderblock to QuickBooks Online and sync supported accounting records. Handle your invoices in Cinderblock without having to maintain separate copies of the same billing information.

It Keeps My Schedule Sorted, Even on Busy Days

Beyond lockouts, I take on recurring work and installs for complexes. Cinderblock lets me break the work into steps and track what’s been finished without mixing it up with other jobs.

From One Service Call to a Multi-Day Installation

A lockout can be finished in one visit. A commercial master-key job might involve dozens of doors, new hardware, and several trips back to the property.

Cinderblock gives you one place to handle the work, no matter how many visits it takes.

Emergency Lockouts: Assign, Complete, Invoice

A driver calls because the keys are locked inside the car.

Create the work order, add the location and service details, and assign a technician. They can check the appointment on their phone, record what they did, and send the invoice before heading to the next call.

The completed job stays in the customer’s history if they need service again.

Commercial Installations: Keep Every Visit Accounted For

An office building needs a new master-key system. Some doors need replacement cylinders. Others need new hardware.

Build the estimate, schedule the installation visits, and assign tasks to your crew. Keep door schedules, keying instructions, hardware details, and photos with the job.

When a technician returns, they can see what was finished and what still needs work. No need to piece together updates from different people.

Some locksmith businesses also install electronic locks, card readers, and keypad systems. If that’s part of your work, see how Cinderblock supports access control contractors.

For jobs where costs matter as much as the schedule, the Build plan adds time tracking, purchase orders, and job costing.

The Tools You Need to Run a Locksmith Business

From answering the first call to collecting the final payment, Cinderblock handles the paperwork and scheduling that come with running a locksmith shop.

Job Management

Keep work orders, service notes, hardware details, photos, and invoices together. Find what you need without searching through different apps.

Scheduling and Technician Assignment

See who’s booked, assign new calls, and move appointments when an emergency changes the day’s plans.

Look up previous lock changes, rekeys, and service visits. Know what your crew worked on before you return.

Tasks and Follow-Ups

Estimates and Invoices

Purchase Orders

Keep hardware purchases and vendor records tied to installation jobs. Included in the Build plan.

Mobile App

Check schedules, update work orders, take photos, and invoice customers from your phone. Some tasks also work when you’re offline.

Team Communication

Leave notes and tag coworkers on jobs so the next technician knows what happened on the last visit.

Create Locksmith Invoices Before You Leave the Job

Send an Estimate

For planned work, put the labor, hardware, and service charges into an estimate.

Send it to the customer for review and electronic signature. You have an agreed scope and price before your crew gets started.

For a standalone estimate, you can also use the free contractor estimate generator to itemize labor, hardware, and service charges.

Create the Invoice

Turn an accepted estimate into an invoice, or create one directly after a service call.

For longer installations, progress billing lets you bill for completed work without waiting until the entire job is finished.

Collect Payment

Send the invoice and let the customer pay online by card or ACH.

You can check which invoices have been paid and which still need attention, without sorting through paper receipts at the end of the day.

Create Locksmith Invoices Before You Leave the Job

A service call might involve more than one charge. Maybe you replaced a deadbolt, rekeyed three cylinders, and charged for the trip.

Cinderblock lets you put each item on the invoice so the customer can see the cost of the work. Add taxes or discounts, send it from your phone, and give the customer a way to pay online.

For example, a residential lock-replacement invoice could look like this:

Example locksmith invoice

Service call: $75
Rekey three cylinders: $105
Replacement deadbolt: $85
Installation labor: $60
Subtotal: $325

Before applicable taxes or other charges.Illustrative prices only. Actual locksmith rates vary.
