The platform we built for our own trade businesses — quote, manage the job, get paid, all in one place. Now yours.
Field service software is stuck in 2015. Built by holding companies, sold by sales reps, used by people who've never written an estimate on a tailgate.
Kickserv, Jobber, and Housecall charge $60–$80/mo for tools that look like they were designed in 2014. Senku starts at $0 and Pro is $45.
Measure, calculate, type, format, send. By the time you've finished writing the proposal, the lead is cold. AI-drafted line items get you to a clean estimate in five.
Quote in one app. Schedule in another. Invoice in QuickBooks. Track payments in your head. Five tools, four logins, zero clarity.
Quiz funnel captures the lead. AI drafts the line items from a job description. Customer reviews and e-signs from their phone. Branded PDF generated automatically.
Stripe deposit when the contract is signed. Final payment collected in the portal. Cash, check, Venmo, and Zelle logged in the same flow.
Revenue dashboard with collected, outstanding, and lifetime balances. Materials catalog priced your way. Receipt OCR pulls vendor and totals straight off the photo.
BUILT BY CONTRACTORS, FOR CONTRACTORS. EVERY FEATURE EXISTS BECAUSE WE NEEDED IT.
Senku is a product of SJ Tech Solutions. We build it because we run trade businesses ourselves, and the tools we kept reaching for were either too generic, too expensive, or too clunky to actually use on a job site.
Fast itemized estimates. A customer portal that doesn't require an account. Online payments that go straight to your own bank. A revenue page that finally answers “how much did I actually make this month?”
We're a small team. You can email us anytime at hello@senkulab.com and a human responds.
We won't lie about features we don't have. Here's a real, side-by-side look at what you get for your money.
