Choosing help to integrate payments, WhatsApp or a CRM

You're running your business on separate tools: a payment processor, WhatsApp for customer chat, maybe a spreadsheet doing CRM work. Right now, they don't talk to each other. Data lives in silos. You're tempted to hire someone to wire them together, but you're unsure whether you actually need custom development or if a simpler bolt-on tool might be enough. The real question underneath is: which path avoids waste and gets you moving fastest?

The choice between hiring a developer to build a custom integration and buying an off-the-shelf connector (or doing nothing and accepting manual work) hinges on three things: how much manual labour your current setup costs, how unique your workflow is, and whether your tools even *can* talk to each other without custom code.

When a ready-made connector works better

If your payment processor and CRM already have a native Zapier, Make, or similar integration available, and that automation covers your exact need, a developer is unnecessary. You pay a subscription—usually modest—connect two apps in an afternoon, and you're done. No ongoing code maintenance, no version conflicts, no risk of a platform update breaking your link.

This works if you're using mainstream tools: Stripe to Shopify, Square to HubSpot, PayPal webhooks to a standard invoicing app. These connectors are battle-tested by thousands of businesses. The cost of picking this path is low; the cost of picking it *wrong*—when it doesn't actually do what you thought—is just lost subscription money and a few hours of your time.

When custom integration makes financial sense

Hire a developer when the off-the-shelf connector doesn't exist, or when it covers only 60% of what you need and the remaining work has to be manual anyway. For example: you need WhatsApp messages to automatically log into your CRM *and* trigger a payment request *and* update your inventory, but the available connectors only handle the first two. Or your payment system is older, rarely supported by third-party automation.

Calculate the cost of the problem first. If one person spends two hours a week wrestling spreadsheets or re-entering data, that's roughly 100 hours a year. If their time is worth R250 to R400 per hour (even as a rough internal shadow cost), you're looking at R25,000 to R40,000 in annual waste. A developer building and deploying a custom integration typically costs R5,000 to R15,000 in freelancer rates, plus maybe R500–R2,000 a month for ongoing support if anything breaks. Over a year, custom development usually pays for itself if the manual work is real and frequent.

The hidden cost of picking wrong

Choosing a connector that almost works, then trying to patch the gaps with manual workarounds, often costs more than either pure option. You pay the subscription, you still pay the person-hours, and you've now got two systems to manage. Similarly, choosing custom development when a connector exists means you're paying for maintenance and complexity you don't need—and if the developer moves on, you own the code.

The most expensive mistake is underestimating how much your tools drift apart. If your payment system updates its API and your custom integration breaks, you're back to manual work while waiting for a fix. Off-the-shelf connectors are usually updated by the vendor at no cost to you.

Framing the decision with your developer

If you do hire someone, be explicit: "Does a standard connector solve this, or do we need custom code?" A competent freelancer will tell you honestly. Ask them how they'd test it, what they'll do if a payment platform updates, and whether they'll hand you documentation so someone else can maintain it.

On Strove, you can find developers who specialise in integration work and have track records showing what they've built. Check their reviews for mentions of similar payment or CRM work, and ask in your initial quote request whether they'd recommend a connector or custom code for your specific setup. The right answer often isn't the fancier one—it's the one that solves the problem with the least moving parts.
