Third-party services, engineered in.
A payment, a message, a synced record — each integration looks like a toggle and behaves like an engineering project. The work here includes the half the demos skip: webhooks that survive retries, reconciliation that agrees, failure paths a human hears about.
The honest framing, first. Integrations fail in predictable places — webhook handlers that crash on retries, syncs that duplicate quietly, rates that guess, embeds that tax page speed. Anybody can wire the happy path in an afternoon; the engagement here is the unhappy paths, tested before your customers find them. Fixed quotes, no invented numbers — scopes vary by an order of magnitude between "a payment link" and "a reconciled CRM sync", and the quote reflects which one you actually need. Direct contact if you already know what you need.
Pay and get paid
Stripe Integration
Stripe is the best-documented payment platform on the internet — and integrations still fail in predictable places: webhook handling, subscription state, and the gap between "money moved" and "system knows". Those are the places this work covers.
PayPal Integration
PayPal remains where whole customer segments live — and it integrates differently from every other gateway. Wired properly it lifts checkout conversion; wired lazily it adds a second payment system that disagrees with your orders.
Razorpay & India Rails
Selling to India means UPI-first checkout, netbanking long-tail, and settlement mechanics that differ from Western gateways. Razorpay bundles the rails; the integration makes them agree with your orders.
POS & Inventory Syncs
Hybrid retail dies by inventory drift: the website sells what the counter already sold, or the shelf sits on stock the site marked gone. The sync is unglamorous, exacting work — and it is the difference between one business and two quarrelling ones.
Talk to customers
Twilio: SMS & Voice
SMS is the channel people actually read — which is exactly why it is regulated, filtered and easy to get wrong. Twilio supplies the rails; the integration supplies the judgment.
WhatsApp Business API
In much of the world, WhatsApp is the inbox. The Business API turns it from a side channel into infrastructure — with template rules, conversation windows and consent mechanics that punish improvisation.
Email Stack & Deliverability
Transaction email is the nervous system of a site — receipts, resets, notifications — and the default WordPress send is why it dies in spam. The fix is architecture, not another plugin.
Slack & Teams Notifications
The cheapest operations upgrade most teams never buy: the site tells the channel when something happens — a lead lands, an order fails, an error spikes — instead of someone refreshing a dashboard to find out.
Data and operations
CRM Integrations
A CRM that depends on humans copy-pasting from contact forms is a spreadsheet with ambition. The integration is unglamorous field-mapping work — done with the rigor that keeps the database clean instead of polluted.
Accounting Syncs
The books close slowly when a human re-types the store's month into QuickBooks. The sync moves every invoice, payout and fee across automatically — and the hard part is the mapping, not the pipe.
Google Maps & Places
Every maps embed is a JavaScript tax on your page speed, and every review widget is an API relationship with billing surprises. Wired properly, locations enrich a page; wired lazily, they slow it and invoice you.
Booking & Scheduling
The booking question is never whether a scheduler should be custom-built — it is whether your booking rules are simple enough to buy or specific enough to build. The honest answer differs per business, and this page holds both.
Shipping & Fulfillment
Shipping is where ecommerce margins go to die quietly: guessed rates eat margin, manual labels eat afternoons, and "where is my order" emails eat the team. The integration fixes all three with the same pipe.
Airtable & Notion Backends
Airtable and Notion make astonishingly good small backends — and astonishingly bad medium ones. The skill is knowing which side of that line your project lives on, before the build, not after.
What this section deliberately does not do. "Connect anything to anything" promises — some integrations should not exist, and the consult says so when the honest answer is a better process instead of a pipe. Scraped data and API-term workarounds — the front door or nothing. Integration for its own sake — if a manual export genuinely costs less than maintaining a sync, the quote says keep the export. The stack-level view of which services a build needs lives in the integrations stack page; scoping chaos prevention, in the integration requirements template.
Not sure which integration you need — or whether you need one?
Describe what should happen when something happens ("when someone pays, grant access and tell Slack"). The reply is a scoped, fixed quote — or the honest note that a ten-minute tool beats an engagement.
