1. Understanding Your Customer

Before selling anything, understand who you are talking to and what keeps them up at night. Most contractors share the same frustrations:

❌ The Pain: "I spend my evenings typing invoices on my phone, chasing clients for payment, and I still have no idea if I made money this month."

The Contractor's Daily Reality

The Three Types of Contractor You Will Meet

Type Description Best Approach
The Hustler Solo operator, busy, no time for admin. Uses WhatsApp for everything. Lead with the WhatsApp bot. "New invoice" command demo lands in 60 seconds.
The Grower Has a small team or subcontractors. Wants to look more professional. Lead with branding, contracts, and client portal. Show the invoice PDF link.
The Established Pro Busy, has clients, but admin is messy. Losing money on unpaid invoices. Lead with overdue tracking and payment reminders. Show the pipeline numbers.

2. Your Unique Selling Points

WhatsApp reminders 14–90 days before anything expires. AI Trade Check lists what you may be missing for your trade. Never lapse a compliance document again.

Reviews & Follow-ups NEW Automated WhatsApp review requests after job completion. Clients rate 1–5 stars. Optional redirect to Google Business review page for satisfied clients. Ratings aggregate on the public contractor profile. More 5-star reviews = more leads. Google redirect turns happy clients into public proof. Ratings feed into SOS dispatch priority — better reviews = more jobs.

Google Drive Integration NEW Connect Google Drive to browse, upload, and manage files without leaving the portal. Link Drive files to specific job records. Site photos, compliance certificates, and signed contracts all in one accessible place — without switching between apps.

3. The WhatsApp Bot — Full Command Reference & Natural Language Guide

This is one of the most powerful selling points. Contractors live on WhatsApp. Finance OS meets them there. Every command below is available from their own WhatsApp number — no app switching required.

📡 How it works — Shared WhatsApp Instance:

Finance OS runs on a single shared WhatsApp number for the whole platform. The platform owner sets up one GreenAPI account once. Each contractor only saves their own cell number in Settings — the system recognises them by their number when they message the bot. No contractor needs their own WhatsApp API account, no separate setup, no extra cost per user.

What each contractor does: Go to Settings → Integrations, enter their WhatsApp number, enable the bot toggle, and send a test message to confirm it's working. That's it — fully connected in under 60 seconds.

4. Pricing & Offer

Free Trial — 30 Days

R0 / 30 days

Full access. No credit card. No catch.

Full Access — After Trial

R399 / month

Cancel any time. No lock-in.

Less than R13/day for a complete finance + business system

How to Position the Price

R399/month is easy to justify once you reframe it:

Trial Close Script

"Finance OS is free to try for 30 days — the full Contractor Hub, invoicing, quotes, GPS, contracts, bookings, payroll, analytics, everything. No credit card. After 30 days it's R399 a month, and that's when the WhatsApp Bot unlocks — so you can create a full invoice by typing on your phone in 60 seconds. Most contractors who try it don't go back to doing it manually. Want me to get you set up today?"

Setup is Always Free

"Setup is completely free — I'll personally get your account configured, your business details loaded, and walk you through the app. Takes about 10 minutes. The 30-day trial starts from there, and at the end of the trial, it's R399 a month to continue. You've got nothing to lose — let me get you set up now."

5. Sales Channels — Where to Find Contractors

📱 WhatsApp Groups

Join or create local contractor and tradesperson WhatsApp groups. Post a short message with your booking link or a screen recording of the WhatsApp bot creating an invoice. These groups spread by word of mouth extremely fast.

Example post: "Hey guys — built a tool specifically for contractors. Invoices, quotes, contracts, job bookings, overdue reminders, payroll — all in one place. Free 30-day trial, no credit card. R399/month after that — which also unlocks the WhatsApp Bot so you can create a full invoice from your phone in 60 seconds. Setup is free. DM me for a quick look."

📘 Facebook Groups

Target groups like "Plumbers South Africa", "SA Contractors", "Freelancers SA", "Handyman Services Johannesburg". Post a short video demo or flyer. Boost posts with R50–R100 Facebook ads to reach tradespeople in specific areas.

🎵 TikTok / Instagram Reels

Short 30–60 second videos perform extremely well. Show the WhatsApp bot — type "new invoice", walk through the flow, show the shareable link being created in under 2 minutes. Show a client accepting a quote on their phone. Organic reach in this niche is very high.

🤝 Referral Programme UPGRADED

Every contractor has a unique referral link built into their dashboard (Contractor Hub → Referrals). When someone signs up using that link, both the referrer and the new signup get 1 month free — applied instantly and automatically. No manual approval, no admin work. The referring contractor can copy their link or share it directly to WhatsApp with one tap. This is your most powerful growth channel — contractors talk to other contractors every day on-site and in trade groups.

🏗️ Hardware Stores & Suppliers

Partner with local hardware stores, paint shops, and building suppliers. Leave flyers at the counter or offer the store owner a commission per referral. Contractors visit these stores weekly.

💼 LinkedIn

Target self-employed professionals, IT contractors, designers, and consultants. LinkedIn works well for the professional/freelancer segment rather than tradespeople.

📧 Cold SMS Outreach

Source contractor contact numbers from Gumtree, Facebook Marketplace, or local business directories. Send a short personalised SMS: "Hi [Name], saw your listing for electrical work. Built a tool that creates invoices and quotes via WhatsApp in 2 minutes. Free setup right now — reply YES for a link."

6. The Sales Conversation

Step 1 — Open with a Question, Not a Pitch

"How are you currently sending invoices to your clients?"

— or —

"If a client hasn't paid, what do you do right now to follow up?"

Let them describe the pain. The more they talk, the easier your pitch becomes.

Step 2 — Reflect the Pain Back

"So you're doing your admin at night after a full day on-site, typing invoices manually in WhatsApp or Word — and even then some clients still take weeks to pay. Is that right?"

Step 3 — Introduce Finance OS

"What if you could create a professional invoice with multiple line items, the client's details, and a payment link — from WhatsApp, in under 2 minutes, while you're still at the job? And when someone goes overdue, one tap sends them a reminder? Your clients could also book jobs directly from your WhatsApp bio — no phone calls needed."

Step 4 — Live Demo (3 minutes is enough)

Show these three things in order — they always land:

  1. WhatsApp "new invoice" — walk through the bot flow live. Add two line items. Show the shareable link that comes out. This is the show-stopper.
  2. Type "jobs" — show the bot replying with the live job list. Fast, clean.
  3. Booking page — "this link goes in your WhatsApp bio, clients fill in a form, you approve and it becomes a job. No more missed leads."

Step 5 — Handle the Price

"Finance OS is free to try for 30 days — no credit card, full access to everything except the WhatsApp Bot: the Contractor Hub with all 19 tabs, invoicing, quotes, GPS trips, contracts, bookings, subcontractors, inventory, retainers, payroll, compliance, safety, warranty, reviews, Google Drive — the whole thing. After 30 days it's R399 a month, and that also unlocks the WhatsApp Bot. Less than R13 a day for a complete business system. Setup is always free — I handle it personally."

Step 6 — Close with the Next Step

"I can get you set up in about 10 minutes — just your business name, logo if you have one, and your WhatsApp number. Want to do it now while I'm here, or should I send you the signup link?"

7. Handling Objections

Objection: "I already use Excel / WhatsApp / a free app."
Response: "Those tools aren't built for contractors. You can't create an invoice from a WhatsApp message, you can't have clients accept quotes online, and they don't remind clients automatically when they're overdue. The time you spend doing that manually is time you could be on-site earning."
Objection: "R399 is too expensive."
Response: "You've had 30 days to use it for free — you already know what it does. At R399 a month that's R13 a day for something that handles your invoicing, chases your overdue clients, and lets you create a full invoice from your phone in 60 seconds. One recovered overdue payment covers the entire month. Is there a specific feature that hasn't delivered value? Let's fix that first."
Objection: "I'm not good with technology."
Response: "It's built around WhatsApp — which you already use every day. Most of what you'll do daily is just type a word like 'new invoice' and answer a few questions. I've had contractors in their 50s fully set up in 10 minutes."
Objection: "Let me think about it."
Response: "Of course. Just keep in mind setup is free and I'll personally get you going — takes about 10 minutes. Can I check back in two days?"
Objection: "I don't have many clients yet."
Response: "That's actually the best time to start — you build professional habits from day one. When clients receive a branded invoice with a payment link and a contract to sign, they trust you immediately and you win bigger jobs faster."
Objection: "What happens if I cancel?"
Response: "You can cancel any time from within the app — no phone calls, no forms. You keep access until the end of your billing period, and your data is kept for 90 days in case you want to come back."

8. Onboarding a New Contractor (10-Minute Setup)

The easier and faster onboarding feels, the less likely they are to cancel. Walk every new customer through these steps:

# Step What to Do
1 Register & Log In Create account via invite link, verify email, accept Terms & Privacy Policy
2 Business Profile Add business name, logo, accent colour, contact details, banking info
3 Invoice Prefix Set prefix (e.g. INV, JOB, ELEC) — personalises every invoice number
4 Payment Methods Add SnapScan QR / EFT details / Cash — shown on every invoice automatically
5 WhatsApp Integration Connect GreenAPI instance — takes 5 minutes, free tier available. Enable Commands in Settings → Integrations.
6 Test WhatsApp Bot Send "help" to the WhatsApp number — confirm the bot responds with the full command list
7 Create First Invoice via WA Type "new invoice" on WhatsApp, walk through the flow, copy the link and open it — show them how it looks to a client
8 Add a Client Type "new client" on WhatsApp — add their first real client. Now that client is ready to use on next invoice.
9 Booking Link Go to Contractor Hub → Bookings, copy their booking link, paste it into their WhatsApp bio or website
10 WA Command Toggles Go to Settings → Integrations → WA Command Toggles — turn off any commands they don't need to keep things clean
11 Menu Layout Go to Settings → Appearance → Menu Layout — drag to hide sections they won't use (e.g. hide Bond Simulator, UIF, etc.) so the sidebar stays clean

Pro tip: Do steps 6, 7, 8, and 9 with the client watching. Seeing it work in real time with their own data removes all doubt and sets the habit immediately.

Where to Find Contractor Contact Numbers

Daily Activity Targets

To sign 5 new contractors per week, you need:

The 5-Touch Follow-Up Sequence

Most sales happen on the 3rd to 5th contact. Stop after the first message and you leave money on the table. Work every lead through this sequence before marking them as dead.

Day 1
First contact — Send the cold WhatsApp or SMS (see Section 11). Keep it short and end with one question. Do not pitch everything at once.
Day 3
First follow-up — If no reply: "Hi [Name] — just checking if you saw my message. I can show you a quick 3-minute demo over WhatsApp if that's easier — just let me know."
Day 7
Second follow-up — add value — Send a short screen recording of the "new invoice" WhatsApp flow in action. No pitch. Just: "Thought you'd find this useful — this is how the invoice gets created from WhatsApp in under 2 minutes 👇"
Day 14
Third follow-up — pain angle"Hi [Name] — quick question: do you currently have a way to see which clients owe you money at a glance? That's one of the things Finance OS handles automatically — just curious if that's ever an issue." Engage with their answer before pitching.
Day 30
Final touch — soft close"Hey [Name] — last message from me, I promise. If the timing isn't right, no stress. When you're ready to sort out your invoicing and get overdue clients paying faster, just reply and I'll get you going. Setup is free and takes 10 minutes." Then leave them unless they reach out.

Cold Call Script (Phone)

Phone calls convert faster than WhatsApp when you can reach them. Use this framework:

[OPEN — 10 seconds]
"Hi [Name], my name's Justin. I found your number on Gumtree — I hope that's okay. Do you have 30 seconds?"

[BRIDGE — 20 seconds, wait for their answer]
"I've built a tool specifically for contractors called Finance OS. Quick question — how are you currently creating invoices and quotes for your clients?"
(Shut up. Let them talk. The more they describe their current frustration, the warmer they become.)

[CONNECT PAIN — 20 seconds]
"Yeah, a lot of contractors tell me the same thing — typing invoices on the phone at night, clients that take weeks to pay, no way to know what's overdue. Is any of that relevant for you?"

[ONE-LINE PITCH — 15 seconds]
"What Finance OS does is let you create a full professional invoice — with line items, payment details, and a link you can send the client — directly from WhatsApp in under 2 minutes. No laptop, no app, just WhatsApp."

[ASK FOR THE DEMO — 10 seconds]
"Would it be worth 5 minutes for me to show you how it works? I can do it over a WhatsApp call right now, or whenever suits you this week."

Cold WhatsApp Voice Note Strategy

A 30-second voice note outperforms a text message in SA because it feels personal and stands out. Most people will listen out of curiosity. Use this structure:

[Voice note — 25–35 seconds]

"Hey [Name] — my name's Justin, I found your number on Gumtree. I've built a tool for contractors called Finance OS. Basically you can create a full invoice with line items and a payment link directly from WhatsApp in about 2 minutes — no app needed. Also handles overdue reminders, contracts, and job bookings. Setup is free. If you want me to show you a quick demo, just reply and I'll send you a 3-minute video or we can chat. No pressure 👌"

Cold Email Template

Use for contractors with a listed email (Google Maps, their website). Keep it short — 5 sentences maximum.

Subject: Invoices & quotes from WhatsApp in 2 minutes — Finance OS

Hi [Name],

Saw your listing online — I've built a tool called Finance OS specifically for contractors like yourself.

It handles invoices, quotes, overdue reminders, online quote acceptance, signed contracts, and job bookings — all in one place.

There's also an optional WhatsApp bot add-on: type "new invoice" on WhatsApp, answer a few questions, and a professional invoice with your logo, line items, and a payment link is ready in under 2 minutes. No app, no laptop.

Free for 30 days — full app access, no credit card required (WhatsApp Bot not included in the trial). After the trial it's R399/month, which unlocks the WhatsApp Bot and gives unlimited access. Setup is always free and I do it personally.

Worth a quick 5-minute demo? I can show you over WhatsApp video.

What to Invest Revenue Into at Each Stage

16. Converting Trial Users to Paying Subscribers

The 30-day free trial is your best sales tool. By day 30, the contractor has used it, seen the value, and knows exactly what they're paying for. Your job in the trial period is to maximise usage — because a contractor who has sent 5 invoices and chased 2 overdue payments through Finance OS will not cancel. Here's how to run the trial month.

The 30-Day Conversion Timeline

Why You Must Not Extend the Trial

The Value Stack — Use This at Day 21

"At R399 a month — R13 a day — let's put that in context. A bookkeeper costs R1,500 to R3,000 a month and doesn't take WhatsApp commands. One recovered overdue invoice covers the entire subscription. You've had 30 days to see what this does for your business. R399 is not a risk — it's a continuation of something you already know works."

When They Say "Can You Do R500?"

"The price is R399 for everyone — that's what makes it fair. What I can do is make sure your setup is maximised so the moment you go onto the full plan, everything works immediately — your templates, booking page, and WhatsApp Bot all live from day one. That way the first month pays for itself. Does that work?"

Anchoring — Before You Mention the Price

Always establish value before quoting the number:

  1. Ask "how many invoices did you raise this month through the app?"
  2. Ask "how many hours do you think that saved you?"
  3. Let them say a rand value for their time
  4. Then: "Finance OS is R399 a month — R13 a day."

When they've already told you it saved them R1,200 this month, R399 is obviously cheap. Let them do the maths.

The Day-30 Close

"Your free trial ends in a few days. Based on everything you've used this month — invoices, your booking page, contracts, compliance — do you want to keep it running? I'll activate the full plan now at R399 a month, that turns on the WhatsApp Bot so you can create invoices straight from your phone, and your referral link goes live so sharing it with a colleague earns you both a free month. Cancel any time."
