Electricians often need to make lightning-fast technical decisions in the field to provide the best and most efficient service while keeping their customers safe.
There are numerous electrician apps that streamline these processes for you and replace having to rely on reference books and manuals to look up electrical formulas and do on-the-spot calculations.
Choosing the right app depends on several factors:
The size of your team
Your business size and scaling goals
The features that you actually need and will use
The software’s ease of use
Your budget
If you have a small business with one or two electricians and don't plan to scale, free or low-cost apps may suffice. However, if you're looking to grow your electrical business while maintaining customer satisfaction and operational efficiency, an all-in-one field service management solution (like ServiceTitan) that streamlines workflows such as call booking and dispatching, and provides your techs with everything they need via mobile device, might be more suitable.
We’ve compiled the 20 best apps for electricians, starting with a walk-through of ServiceTitan.
Our list features apps for calculating voltage drop and cable sizes, along with tools for reference guides, invoicing, and route planning.

1. ServiceTitan: Best All-in-One Electrician App
ServiceTitan is a cloud-based software platform that helps home services companies — including electrical contractors — run their business more efficiently, improve customer service, and increase sales. Our mobile app gives electrical contractors (and other field services businesses such as plumbers and HVAC) the agility to work from any location and sync entire workflows with other team members (like CSRs and dispatchers) and electrical business owners based in the office.
ServiceTitan Mobile replaces a whole range of paper-based processes because all customer documents — invoices, estimates, memberships, contracts, etc. — are uploaded to the cloud. It's intuitive and user-friendly for techs (and the main office) to keep track of these important documents and access them on any device in real-time.
By using our mobile electrician app, ServiceTitan makes it easy for your electricians to:
Access all customer information collected by CSRs (job histories, equipment information, call recordings, and more).
Build instant digital estimates with accurate pricing and product information that customers can approve on the spot.
Offer financing options so that jobs can be closed more quickly.
Maximize upselling opportunities such as maintenance contracts that bring in more revenue.
Create invoices and take payments directly from customers so you get paid faster.
Sign-off timesheets remotely in real-time so payroll is accurate and prompt.
We’ll walk through these features next.
Access Vital Customer Information
With the ServiceTitan Mobile app, electricians can access all the details your CSRs collected during the call booking process from anywhere (contact details, job history, outstanding estimates, prior invoices, notes, and more). No more paper with scribbled information, no more repeated calls between CSRs and techs for job details, and a more efficient way to organize work orders and customer information.
Out in the field, electricians can even listen to a recording of the call without ever having to call the CSR who made the booking. This provides them with a record of exactly what information the customer has already provided about their electrical issue. This reduces communication problems and gives electricians a detailed insight into the problems the customer is facing before they arrive at the appointment.
In addition, recorded calls provide management (and business owners) with a record of how your CSRs deal with calls and where they can improve their approach to increase sales.
Build Digital Estimates on The Spot
With ServiceTitan, electrical businesses can set up a dynamic flat-rate pricebook that’s updated across all devices and systems so you and your team can build accurate estimates that bring in profit.
Pricebook Pro, available on both ServiceTitan Mobile and in the office, comes loaded with curated content, detailed descriptions and vivid images already built in. Your electricians can create Good-Better-Best proposals that show customers a picture and description of the products they recommend on their mobile app, making it easier for them to explain services and products and helping them close more sales.
Once a customer selects their option, ServiceTitan connects the estimate to the rest of the electrical workflow, including scheduling, dispatching, and billing.
Offer Flexible Financing
ServiceTitan’s integrated financing feature helps your techs win more customers by offering flexible financing options while they’re out on a service call.
You control which plans you offer and set the rules to suit your electrical business. Once you’ve built your estimate, ServiceTitan automatically calculates the options, based on your choices, so that financing can be offered directly from your mobile device.
The ability to offer flexible financing options on the spot gives customers instant access to funds and increases the likelihood of techs closing bigger jobs and boosting sales.

Maximize Upselling Opportunities
The ServiceTitan Mobile app gives your electricians the tools to upsell additional services or close an outstanding estimate on all service calls.
Because the complete job history, equipment details, and customer information is stored within the software, electricians can see, at a glance, when wiring might need updating, for example, or an outstanding estimate should be followed up.
Without this in-app information, figuring out which customers would benefit from additional services is challenging, and techs can easily forget or ignore upselling opportunities. When the tech has access to all of the customer information we outlined above, they can follow up on any open estimates and close more jobs.
Collect Check or Credit Card Payments via Your Mobile Device
Making it as easy as possible to pay for a service saves your team the time and effort of following up on invoices and calling customers about outstanding payments.
With ServiceTitan’s free Invoice Generator tool, techs can generate invoices while they’re on site. They can also take payments as soon as the work is completed by capturing check and credit card payments via the tablet’s inbuilt camera (and card payments by swiper). You don’t need to wait days for payments to clear, or chase customers down for payment after the tech has left the job site.
Note: If you already use accounting software, ServiceTitan’s invoicing software can be integrated with QuickBooks to ensure your financials are accurate, up-to-date, and easily accessible. We cover this below in our QuickBooks app section.
Sign Off TimeSheets Remotely
Instead of using a stand-alone timesheet app, ServiceTitan’s payroll software has been designed to help you track staff (via timesheets), and pay them on time.
Our timesheet feature helps you manage productivity by monitoring time spent on specific activities, such as driving and collecting materials, as well as time spent on actual electrical work.
Because ServiceTitan features are fully integrated, techs can access their timesheets for sign-off via their mobile device, so there’s no need to drive in to the head office each payroll period. You can even configure the software to apply confidential commission and bonus structures so that complex performance pay is all automated.
These systems not only streamline your payroll procedure, but your staff will be confident that they will always be paid correctly and promptly.
ServiceTitan Mobile syncs seamlessly with all the operational processes typically done in the office. All features can be viewed in real-time by team members whether they are office-based or out in the field.
ServiceTitan electrical software’s core features include:
