A contractor posted this: "Lost $4k this month on unbilled extra work. The GC said 'just do it' — now he says we never agreed." If your jobs run on verbal OKs, that's you eventually.
Founding members lock in special pricing forever. No spam.
One voice note. That's all it takes to turn forgotten extras into paid change orders.
Rotten wood behind a shower. A code violation someone else left. The homeowner wants an extra outlet. It happens every job.
Talk into WhatsApp like you already do. Describe the work, the materials, the time. Take a photo if you want.
Labor, materials, markup — priced and formatted into a professional document. You review it and hit send.
Forward it to whoever pays — GC or homeowner. They see what the work is, why it's needed, what it costs. One tap to approve. Timestamped, on the record.
No more "I thought that was included." No more eating $500 in extras because you forgot to ask. Every change order documented, approved, and ready to invoice.
Forgotten hours, unbilled materials, change orders that never made it to the invoice. You're doing the work — you're just not getting paid for all of it.
You paid for software. They still text you blurry photos. JobHammers works in WhatsApp — the app they already use 50 times a day.
Sunday night piecing together what everyone did from memory and scattered texts. That's 5 hours you'll never get back.
Procore starts around $500 a month on an annual contract. JobHammers is $49 a month, month to month — built for a 5-person crew, not a 500-person corporation.
ChargeHammer gets you paid. The rest — daily logs, code answers, safety docs — come in the same box. You don't think in modules. You just talk.
