What we build.
Everything Hire WhatsApp API Developers includes — designed, built and shipped for you.
We have migrated live WhatsApp accounts off BSP platforms onto direct Cloud API access under the client own Business Manager, and we know precisely where that process breaks.
Written and categorised so they clear Meta review first time.
Keep the phone app on the same number as the API.
Partner-only fields that fail an entire call, manual-connect flows that skip registration, quality-rating recovery — the things that cost days if you have not hit them before.
Shared inbox, flows, CRM sync and reporting, not a bolted-on widget.
Catalogue, click-to-WhatsApp ads and in-thread payments where supported.

Questions answered.
Still unsure? Email contact@scaleus.in — a real human replies inside 4 hours.
Can you move our WhatsApp number off our current provider?
Yes. We have done exactly this on live accounts — moving off a BSP onto direct Meta Cloud API access under the client own Business Manager, keeping the number and the quality rating.
Why does it matter whose Business Manager it sits in?
Because if the account sits inside an agency or BSP account, the number, templates and quality rating are effectively theirs. Owning it means you can switch vendors without switching numbers.
Can we hire a developer full-time instead of a fixed-price project?
Yes. Dedicated engineers are available monthly, full-time or part-time, with a named developer and direct communication rather than an account manager relay. Most clients start with one fixed-scope build and move to a monthly team once they have seen the work.
How quickly can you start?
Onboarding takes under a day and a first working draft usually lands within two to three days. We keep overlap with US, UK and Australian business hours so you are not waiting a full day for each reply.
How much does this cost?
Most single-scope builds land between $2,500 and $4,000 as a fixed price. Multi-location or heavily integrated work runs $10,000 to $25,000, and a full platform build is $25,000 to $50,000. Once live, managed support is $900 to $1,500 a month. We quote fixed scope so you are not exposed to an open-ended hourly meter.
Who actually does the work?
Our own engineers, not a subcontracted chain. The team has delivered production apps as a Tier 1 delivery partner to a $1.3B-valuation UK app platform serving US and UK SMBs, plus our own products running in 60+ countries. You get named engineers and a direct line to them.
