Solo Locksmith Operators
Invoice from your phone between every call. No office, no laptop, no end-of-day paperwork. Send and get paid before the next job starts.
Locksmith invoicing software built for the field
Invoice software built for locksmith businesses.
Most locksmith calls end with a card payment. KoPay is locksmith billing software that lets you invoice on-site from your phone, pass the processing fee to the customer, and get paid before you leave — without any paperwork or end-of-day admin.

The card fee problem for locksmiths
Small tickets, high volume, and a 3.4% leak on every card payment.
Locksmiths deal with a math problem that most invoicing software ignores. You're running high call volume — lockouts, re-keys, installs — with average tickets in the $100–$300 range. And almost every customer wants to pay by card.
At 2.9% plus $0.30 per transaction, a $150 lockout call costs you $4.65 in processing fees. That sounds manageable until you do it 10 times a day. Five days a week, 50 weeks a year — you're handing over roughly $11,625 annually to payment processors, and most locksmith billing software just accepts that as a cost of doing business.
KoPay doesn't. KoPay automatically calculates the processing cost and adds it to every invoice as a disclosed line item. They see it before they pay. You collect your full rate on every call, every time.
We built KoPay for businesses like yours — where the work is fast, the payments need to happen on the spot, and software that requires you to go back to a desk is software that doesn't actually work. We're a US-based team, and we update the product based on real feedback from real service businesses.

Who it's for
Locksmith invoicing software for every type of locksmith operation
Whether you're a solo locksmith running emergency calls or a multi-tech locksmith company with commercial accounts, KoPay handles mobile invoicing, payment collection, and customer records the same way across every locksmith business model.
Emergency Lockout Services
Fast invoicing for high-urgency calls. Customer gets an invoice immediately after service with a pay link — no waiting for a mailed invoice.
Automotive Locksmiths
Invoice per service — key cuts, programming, lockouts — and pass the card fee so every job pays your full flat rate without processing deductions.
Residential Locksmiths
Re-keys, lock replacements, and installs — create professional invoices with line items for parts and labor. Send for payment before you pack your tools.
Commercial Locksmiths
Larger jobs for businesses and property managers. Send signed estimates before major installs, then convert to invoices when work is complete.
Multi-Tech Locksmith Companies
Add multiple technicians with their own access. Each tech invoices their own calls; the office sees everything in one dashboard and tracks what's paid.
The real math for a busy locksmith
What fee pass-through means for a locksmith doing 200 calls a month
Let's run the numbers. A locksmith averaging 200 service calls per month with an average ticket of $165 and 80% paid by card is running approximately $26,400 in monthly card transactions — about $316,800 annually.
At standard Stripe processing rates (2.9% + $0.30 per transaction, 2,400 card transactions per year), that's roughly $10,007 in annual processing fees disappearing before the money hits your account.
With KoPay, that $10,007 is added to customer totals instead of subtracted from your revenue. Over three years, that's $30,000+ back in your pocket — enough to buy a new vehicle, upgrade equipment, or hire additional help.
For solo operators and small locksmith companies, this isn't a minor optimization. It's a meaningful shift in how profitable the business actually is. Customers are generally accepting of disclosed fees — especially for emergency services they needed immediately. Transparency before payment beats a surprise charge on their statement every time.
