Your current process is costing you jobs.
Send quotes that win jobs.
A profession branded quote builds trust before you have lifted a tool. Clients are more likely to sign when it looks like you run a proper business.
With Certi → Certi generates professional A4 quotes with your branding, line items, and terms — sent from your phone in under a minute.
Stop eating the cost of extra work.
You have heard it — I thought that was included. Every photo, every change, every conversation needs to be logged or you are the one who pays.
With Certi → Certi timestamps every photo, change, and conversation automatically. If a client disputerk, you have the proof.
Get it signed before you start.
A WhatsApp yes is not a contract. Three weeks in, clients forget what they agreed to and you end up doing extra work for free.
With Certi → Certi sends a digital contract in one tap. Client signs on their phone. IP-logged, timestamped, legally binding. No arguments.
Bulletproof your jobs. Never get screwed on payday again.
