GoHighLevel integration connects your CRM to the rest of your stack — website, payment platform, calendars, WhatsApp, accounting, and any system with an API — with error handling, retry logic and alerting built in rather than added later.
Standard integrations start at £795 and take three to five days. Custom API development starts at £1,995, excluding VAT.
Most businesses running GoHighLevel also run a website, a payment platform, an accounting system and two or three other tools. When those do not talk to each other, someone ends up re-keying data — and the moment that happens, the CRM stops being the single source of truth.
The integrations that cause the most damage are not the ones that never worked. They are the ones that worked for eight months and then quietly stopped, with nothing alerting anyone and no error surfacing anywhere visible.
An integration is not finished when it passes once. It is finished when it handles failure predictably and tells someone when it does.
Integration suits businesses re-keying data between systems, or depending on connections nobody has documented or tested.
Your website forms are not reaching the CRM reliably
Payments happen in Stripe but nothing updates in GoHighLevel
Someone is re-entering the same data into two systems by hand
You need two-way sync rather than a one-off push
You have custom or internal software that needs to talk to the CRM
Your existing Zapier or Make setup is undocumented and fragile
If a connection existed and has broken, start with integration repair from £395. We diagnose the cause first. Occasionally an undocumented chain costs more to untangle than to rebuild — if so, we will tell you before spending your money on either.
Most projects combine two or three of these. Scope and method are confirmed after mapping the data flow.
WordPress, WooCommerce, Shopify and custom sites. Form capture, order events, customer records, membership and subscription status.
Stripe, PayPal and GoCardless payment events, subscription status and failed payment handling, plus Xero, QuickBooks and FreeAgent.
Google Calendar, Outlook and Microsoft 365 two-way sync, availability handling and connections to external booking systems.
WhatsApp Business, SMS providers, live chat widgets, and Slack or Teams for routing internal notifications to the right people.
Zapier, Make and n8n, built properly with documentation, error handling and alerting rather than a chain that fails quietly.
REST API integrations, inbound and outbound webhooks, custom middleware, database connections and bespoke internal systems.
GA4, Google Ads and Meta conversion tracking, call tracking, Microsoft Clarity, and reporting into Looker Studio or Databox.
We recommend based on your volume, budget and whether you have technical capacity in-house. We do not build a custom integration to look clever when a native connection works.
| Criterion | Zapier | Make | n8n |
|---|---|---|---|
| Ease of use | Easiest | Moderate | Technical |
| Cost at low volume | Reasonable | Cheaper | Cheapest |
| Cost at high volume | Expensive | Moderate | Lowest |
| Complex logic | Limited | Strong | Strong |
| Hosting required | No | No | Yes |
| Maintenance burden | Lowest | Low | Yours |
| Best for | Simple, low-volume connections | Complex logic at sensible cost | High volume with in-house capacity |
Native connections come first. Where GoHighLevel has a built-in integration that does the job, we use it — fewer moving parts, no third-party subscription and nothing extra to maintain. Custom API work is for when reliability genuinely requires it.
Five stages. Failure handling is designed in from the start rather than added after something breaks.
What moves, in which direction, triggered by what, and what happens when the two systems disagree about the same record.
Native connection where one exists, no-code where it is genuinely sufficient, custom API where reliability at volume demands it.
Error handling, retry logic, deduplication rules and alerting, so a broken sync tells someone rather than disappearing silently.
Including the edge cases: duplicates, partial data, rate limits, and what happens when one of the two systems is down.
A written data flow diagram, so the next person to touch it knows what it does without reverse-engineering it.
Integration moves the data. These services decide what happens to it once it arrives.
Clear answers on cost, platform choice, two-way sync, duplicate handling, security and who owns the work.
Standard integrations are £795, multi-system builds £1,495, and custom API work starts at £1,995. Repairs to existing integrations start at £395. All prices exclude VAT.
If it has an API or supports webhooks, almost certainly. If it has neither, options are limited and we will tell you early rather than after you have paid for discovery.
Zapier is easiest and most expensive at volume. Make is cheaper and more capable for complex logic. n8n is cheapest at scale but needs hosting and maintenance. We recommend based on your volume and in-house capacity.
Where both platforms support it, yes. Two-way sync needs clear conflict rules deciding which system wins when both change the same record, and we agree those during mapping rather than in production.
Everything we build includes error handling, retry logic and alerting so failures surface rather than disappearing. Repairs are covered under monthly management, or billed at £395 as a one-off.
Yes. Repair starts at £395. In some cases rebuilding is cheaper than untangling an undocumented chain, and we will tell you which before starting.
Yes, a documented REST API plus inbound and outbound webhooks. It is capable but has rate limits and some gaps, which we design within rather than pretend do not exist.
Yes, through WhatsApp Business. Message templates require approval from Meta, which usually takes a few days and occasionally longer, and that affects the project timeline.
Connections use encrypted transmission and authenticated credentials held in an encrypted store, never in plain text. Where an integration moves personal data outside the UK, that sits under the safeguards on our data processing page.
Yes. On full payment you own the configuration and any custom code written for you. Documentation is handed over so you are not dependent on us to maintain it.
We design for it — batching, queuing and retry logic rather than firing every event immediately. If your volume genuinely exceeds what the platform supports, we will say so before building.
Yes. Xero, QuickBooks and FreeAgent are common, usually connecting payment and invoice status rather than full ledger sync, which is rarely what businesses actually need.
Tell us which platforms need connecting and what should happen when data moves between them. We will recommend the right method and give you a fixed price.
