Before Certi vs. After Certi

Your current process is costing you jobs.

The Problem

Stop sending amateur PDF quotes.

Your competitors are sending branded, itemised proposals that make yours look like a text message. Clients judge your work by your presentation before you ever pick up a tool.

With Certi → Certi's Quoting Engine generates high-fidelity A4 digital documents with your branding, line items, and terms — sent in one tap.

Scope Creep

End scope creep. Forever.

"I thought that was included" — the five most expensive words in any trade. Without timestamped evidence and signed agreements, you eat the cost every time.

With Certi → The Evidence Vault captures every photo, every change, every conversation — timestamped and audit-ready. CYA: Cover Your Ass.

Closing Deals

The Golden Handshake.

You send a quote, the client says "yeah sounds good" over WhatsApp, and you start work. Three weeks later, they claim they never agreed to half the scope.

With Certi → One-click digital contract signing. Typed signature, IP-logged, timestamped. Both parties get confirmation. Legally binding. Done.

One Platform. Everything You Need.

Project management. Employee tracking. All in one app.

Stop juggling WhatsApp, spreadsheets, Xero, and a notepad. Certi replaces all of it with one platform built specifically for how contractors actually work.

0hrs
per month

The average contractor with 2 employees saves 14 hours every month.

That's nearly two full working days back — every single month. No more chasing paperwork, re-sending quotes, or tracking down who did what. Certi handles the admin so you can handle the work.

Project Management

Create jobs, track progress through every stage, manage scope, and keep every detail in one place. From first enquiry to final sign-off.

Employee Tracking

Assign team members to jobs, track who's on-site, and give your crew direct access to upload evidence and update job status from the field.

Evidence & Compliance

Time-stamped photos, SHA-256 certificates, and a full audit trail — your bulletproof evidence vault that protects you in every dispute.

Quoting, Contracts & Invoicing

Professional quotes, legally-binding digital contracts, auto-generated invoices, and overdue reminders. The full financial lifecycle, handled.

Scheduling & Booking

Book start dates, manage your calendar across multiple jobs, and send automatic client confirmations. No more double-bookings or crossed wires.

Pipeline & Reporting

See your total pipeline value, track payment status across all jobs, and understand where your money is at a glance. Your command center.

Replaces: WhatsApp · Spreadsheets · Xero · Paper invoices · Shared drives · Your notepad

Your Daily Operating System

Not just paperwork. The whole operation.

Quotes and contracts are just the start. Certi runs your entire business — from the first lead to the final margin report.

Pipeline Tracking

Lead & Sales Pipeline

Never lose a £30K prospect to a forgotten follow-up.

Track every enquiry from first contact to signed contract. Visual pipeline stages, automatic follow-up reminders, and conversion tracking. You'll know exactly which deals need attention and which are about to close.

Command Center

Premium Project Management

Your entire operation. One Command Center.

Track every job stage from a single dashboard — quoted, contracted, in-progress, certified, invoiced, paid. No more digging through texts to find out where a job stands. One glance. Full clarity.

Team Scheduling & Dispatch

Live Scheduling

No more 6am phone calls asking 'where am I today?'

Your crew always knows exactly which job they're on, the address, the scope of work, and the client details. Assign, reassign, and schedule from your phone. Morning confusion is over.

Field Evidence & Work Logs

Mobile Upload

Your guys upload proof. You save hours of site visits.

Field workers upload timestamped photos and work logs directly from their phones — during the job, not three days later from memory. This builds your evidence vault in real-time and stops client disputes dead in their tracks.

Real-Time Margin Tracking

Live P&L

Know your profit on every job. Not at year-end. Right now.

See exactly where your margin stands on every active job. Track costs against quoted value in real-time. Spot problems before they eat your profit — not when the accountant calls in January.

The Killer Feature

Compliance Certificates no one can dispute.

Every completed job generates a cryptographically secured certificate — your unfalsifiable proof that the work was done, when it was done, and what was done. No other trade platform offers this.

Beta Feedback

What our early testers are already saying.

Real feedback from contractors in our closed beta programme.

"During testing, a client tried to dispute a £4,200 rewiring job. I pulled up the Certi certificate with SHA-256 proof. Paid in full the next day. This software is an insurance policy."

"Even in beta, the quotes look incredible. My clients already tell me I look more professional than companies ten times my size. I've started quoting 20% higher."

"Certi paid for itself in the first week of testing. One disputed invoice — resolved instantly because I had the signed contract and certificate. Can't wait for the full launch."

"The evidence trail is incredible even in early access. Clients love the before-and-after documentation. I've already had three referrals just from the compliance certificates."
