Before Certi vs. After Certi

Your current process is costing you jobs.

Quoting

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.

Disputes

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.

SHA-256 timestamped evidence trail
Contracts

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.

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

Pipeline Tracking

Lead & Sales Pipeline

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

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.

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.

8 things no competitor can do.

These aren't "nice-to-haves." These are the features that protect your money, save your time, and keep you out of court.

Payment Protection

7-Stage Invoice Escalation

Chases your money for you. Every stage. Every email. Timestamped.

When an invoice goes overdue, Certi starts a 7-stage escalation sequence — from gentle reminder to formal debt notice. Every email includes UK Late Payment Act statutory interest calculations and builds a legal evidence trail. If it goes to court, you walk in with certified proof of every chase, every date, every communication.

Saves 5–10 hours/month
