Why this matters in South Africa
South African construction firms manage multi-site projects with subcontractors, materials orders, progress billing, and retention schedules across spreadsheets and WhatsApp groups. Progress billing disputes and retention holdbacks cost the average SME contractor R200,000+ in annual cash flow strain.
Compliance note: Contractors must be registered with the CIDB at the appropriate grading designation. Electrical and plumbing subcontractors require ECSA or Master Plumbers certification. Construction projects require approved building plans under the National Building Regulations and Building Standards Act.
South African construction firms often lose R200,000 annually to fragmented billing cycles, where progress claims are trapped in WhatsApp threads and manual spreadsheet updates. By connecting Typeform to PayFast, you replace these error-prone manual logs with a structured data pipeline. When a subcontractor or client submits a progress claim or material order via Typeform, the data is captured in a POPIA-compliant format that triggers a payment request. This setup allows you to automate the generation of payment links for ZAR-denominated transactions, ensuring that retention holdbacks and progress billing are tracked systematically before funds leave your account. Instead of chasing paper trails, your project managers receive automated notifications the moment a payment is initiated, providing a clear audit trail for CIDB compliance and SARS reporting. This integration turns your payment process into a predictable, automated workflow that protects your cash flow and reduces administrative overhead.

How to add PayFast to Typeform
- 1
1. Create a Typeform survey that captures essential project data, including the CIDB registration number of the subcontractor, the specific site location, and the net progress claim amount. Ensure the form includes a mandatory field for the subcontractor to acknowledge the project’s specific retention schedule and terms.
- 2
Set up a Make or Zapier account to act as the middleware, as PayFast requires a secure signature generation process rather than a direct API key input within the form itself. This middleware will securely receive the form submission and prepare the transaction data for the PayFast API.
- 3
Configure your PayFast Merchant ID and Passphrase within your chosen middleware to enable the generation of secure payment tokens. You must ensure these credentials are stored in a secure vault to maintain POPIA compliance regarding your subcontractors' financial data.
- 4
Use the middleware to map the Typeform submission data to a PayFast "Ad-hoc" payment request, which generates a unique, secure URL for the specific ZAR amount. This URL is then sent back to the user via an automated email or redirected on the form’s "Thank You" page.
- 5
Direct the user to the PayFast portal via the generated link, as the actual payment processing must occur on the secure PayFast gateway to maintain PCI-DSS compliance. Do not attempt to process credit card details directly within the Typeform interface.
- 6
Implement logic within your middleware to calculate the retention deduction before the payment link is generated, as Typeform’s native logic is insufficient for complex construction accounting. The middleware must subtract the retention percentage from the gross claim to ensure the final ZAR amount requested matches your project’s contractual obligations.
- 7
Ensure that your automated receipt system generates a valid tax invoice that meets the requirements of the VAT Act, including your company’s VAT number and the subcontractor’s details. Automated receipts from PayFast are often insufficient for SARS input VAT claims, so your middleware should trigger a secondary document generation tool like Xero or Sage to issue a compliant invoice.
- 8
Set up a final automated step in your middleware to log the successful transaction status back into your project management spreadsheet or ERP. This ensures that your site managers have real-time visibility into which progress claims have been paid, preventing duplicate payments and disputes over retention holdbacks.

Frequently asked questions
Is PayFast compatible with Typeform?
Yes. PayFast and Typeform can be connected via their APIs or through automation tools like Zapier. This guide covers the exact process for South African construction & engineering businesses.
How long does the setup take?
Most businesses complete the initial setup in 1–3 hours. If you already have active accounts on both platforms, you can have a basic automation running in under an hour.
Do I need a developer?
Not for basic Zapier-based integrations. Custom API integrations will need development support. Melamu Tech Ventures builds these — get in touch if you need a tailored solution.
