THE REAL PROBLEM
The work is done. The money is still out there.
Most contractors aren't losing money because they price badly — they're losing it because follow-up is chaos. A job wraps up on a Friday and the invoice gets sent when you remember, chased when you get a quiet moment, and written off when chasing starts to feel pointless.
Across WhatsApp threads, handwritten notes, and mental tallies, there's no clear picture of who owes what, which jobs are at risk, or how much cash is actually incoming. That gap between finishing the work and getting paid is where thousands of rands quietly disappear.
Follow-ups slip through the cracks
A reminder you meant to send three weeks ago is still sitting in your head.
Money talk feels awkward
So invoices go quiet, and quiet invoices don't get paid.
No single source of truth
Quotes, invoices and “he said he’d pay Friday” live in five different places.

EVERYTHING IN ONE PLACE
From finished job to money in the bank
CollectFlow handles the whole collection cycle — invoice tracking, WhatsApp follow-ups, reminder schedules, and document management — so you spend less time chasing and more time quoting the next job.
Every unpaid invoice in one list
A single live dashboard shows exactly who owes you money, how much, and for how long. Invoices sort automatically by urgency — the most overdue jobs rise to the top with risk flags so nothing slips through the cracks.

Follow-ups written for you
CollectFlow drafts a professional WhatsApp message for every overdue invoice — in a tone you choose — with your banking details and the correct reference number already filled in. Review it, edit if you want, then send straight from your own number.
Reminders that respect a promise
Set a reminder cadence once and CollectFlow handles every follow-up on schedule. When a customer says they'll pay on Friday, log a promise-to-pay and the nudges pause automatically — then resume if the money doesn't arrive.

Quotes and invoices that chase themselves
Send a professional quote, get it accepted, and convert it to an invoice in a single tap. The moment the due date arrives, CollectFlow turns it into a tracked payment request and starts the collection process automatically.
How It Works
Up and running before your next site visit
Three steps to stop chasing invoices manually — no new apps for your customers, no complicated setup for you.
01
Connect WhatsApp & add your customers
Link your existing WhatsApp number and import the people you invoice. No new app for them to install.
02
Log jobs, send quotes & invoices
Capture each job, send a branded quote, and turn it into an invoice the moment the work is signed off.
03
CollectFlow chases the money
Due dates are tracked automatically and every follow-up arrives pre-written, so you just review and send.
Most crews send their first reminder within 4 minutes of signing up.
From the Trades
Crews that stopped leaving money on site
South African contractors share what changed when WhatsApp became their collection engine.
“I had R 40 000 sitting in outstanding invoices across three solar jobs in Durban North. Two customers kept saying they'd pay — same story every week. I sent one WhatsApp reminder through CollectFlow on a Thursday afternoon. Both paid by Friday morning. I'd been chasing those accounts for six weeks on my own. The message looked professional, not desperate, and that made all the difference.”
Sibusiso Mthembu
Solar installer — Durban
“Customers in Pretoria would ghost my calls after the job was done. With CollectFlow they get a WhatsApp with the invoice and a payment link straight away. Most pay within 48 hours now. My average collection time dropped from 21 days to 5.”
Tshepo Maleka
Electrician — Pretoria
“I hate asking for money face-to-face — it always feels awkward after you've just fixed someone's burst geyser at 10 pm. CollectFlow sends the reminder for me and it reads like a friendly nudge, not a demand. I haven't had one difficult conversation about payment since I started using it.”
Ridwaan Patel
Plumber — Cape Town
“Running a building crew in Polokwane means juggling five jobs at once. I used to have my admin lady call clients every Friday — half the time she'd reach voicemail. Now the system chases them automatically. We recovered R 28 000 in the first month just from reminders that were going out at the right time. My admin lady now focuses on quoting new work instead.”
