Professional
contractor and
project management
app.
The platform we built for our own trade businesses — quote, manage the job, get paid, all in one place.
Now yours.
YOUR TOOLS
WEREN'T BUILT
FOR THIS.
Field service software is stuck in 2015. Built by holding companies, sold by sales reps, used by people who've never held a paint roller.
OLD SOFTWARE,
OLD PRICES.
Kickserv and Jobber charge $99–$200/mo for software that looks like it was designed on an iPad mini in 2014. You deserve better.
QUOTES TAKE
30 MINUTES.
Measure, calculate, type, format, send. By the time you've finished writing the proposal, the lead is cold and the homeowner already called the next guy.
NOTHING TALKS
TO ANYTHING.
Quote in one app. Schedule in another. Invoice in QuickBooks. Track payments in your head. Five tools, four logins, zero clarity.
WHY ONE PLATFORM
INSTEAD OF FIVE?
QUOTE IN 5 MINUTES,
NOT 50.
Quiz-based intake captures the job. AI drafts the proposal. Client reviews and e-signs from their phone. Deposit hits Stripe before they close the tab.
- →Quiz funnel that pre-qualifies the lead
- →AI-generated line items, scope, and copy
- →One-tap e-sign + Stripe deposit
RUN THE DAY FROM
ONE SCREEN.
Live crew map. Today's jobs. Who's clocked in, who's on the road, who's at the dropoff. The first thing you check with your coffee, the last thing you check before bed.
- →Real-time GPS pings from the crew app
- →Clock in / clock out with one tap
- →Customizable by trade — paint, landscape, move, concrete
GET PAID BEFORE
YOU LEAVE THE
DRIVEWAY.
Stripe deposits when the contract is signed. Final payment collected on-site or via text link. Mark-as-paid in one tap. Auto-reminders for the slow ones.
- →Stripe + cash logging in the same flow
- →Automated SMS payment nudges
- →QuickBooks export for your bookkeeper
SOUTH JERSEY
“I'M BP. I RUN PERFECT FINISH PAINTERS IN SOUTH JERSEY. I BUILT SENKU BECAUSE NO SOFTWARE DID WHAT I NEEDED.”
Started as a painter. Bilingual marketing, zero ad spend, twenty-five Google reviews from scratch. Tried every CRM out there. None of them fit how the work actually runs.
So I built my own. Quote-to-paid in one place. Crew app that doesn't make my guys hate me. AI that drafts proposals while I'm driving to the next estimate.
Other contractors saw it and wanted in. That's what Senku is.

WHAT IS SENKU?
Senku is a complete estimate, payment, and project-management platform built specifically for trade contractors — painters, landscapers, roofers, HVAC, electricians, remodelers, and similar trades.
WHO IS SENKU FOR?
Solo contractors and small crews who want professional estimates, online payments, a customer portal, and revenue tracking without juggling five different tools.
HOW LONG DOES IT TAKE TO SEND MY FIRST ESTIMATE?
Under five minutes. Sign up, type a job description (or use the AI line-item generator), and email or text the customer a link to a clean, branded estimate.
CAN MY CUSTOMERS PAY ONLINE?
Yes — connect your own Stripe account and customers can pay with a card straight from the estimate. You can also record cash, check, Zelle, and Venmo manually.
IS THERE A FREE VERSION?
Yes. The Free plan covers basic estimating with no credit card required. Paid plans start at $15/mo for additional features like the customer portal, AI estimates, and revenue analytics.
DO I NEED TO INSTALL ANYTHING?
No. Senku runs entirely in your browser on desktop or mobile. You can also add it to your phone home screen for an app-like experience.
WHO BUILT SENKU?
Senku is a product of SJ Tech Solutions. We run trade businesses ourselves and built Senku to solve the problems we kept hitting in the field.
