Integration Services for Any Two Systems
System integration connects the applications your business already runs — ERP, CRM, PIM, HRIS, ecommerce, no-code tools, and analytics platforms — so data moves automatically instead of by hand. We're an independent consultancy: we don't sell a connector, so we recommend the approach that actually fits your stack.
What Are Integration Services?
Integration services connect two or more applications so records — customers, orders, items, invoices, service jobs, candidates — stay consistent across systems without manual re-entry. It's how a Pipedrive deal becomes a Sage invoice, or a Google Workspace form response becomes a task in Monday.com, in minutes instead of days.
Most growing businesses run five, ten, sometimes twenty different systems across finance, sales, operations, and product. Every one of them is a potential silo. Integration turns that stack into a single operating picture, cuts data entry, and removes the errors that come with copying records by hand.
What Can You Integrate?
We integrate almost any modern system that exposes an API, a webhook, or a scheduled export. The categories below cover the majority of our active work.
ERP & Finance
Sage, Cegid, Workday, SAP Business One, NetSuite, QuickBooks
Accounts, invoices, payroll, cost centres, tax
PIM & Supply Chain
Akeneo, Frepple, OCA (Odoo)
Product data, planning, demand forecasts, stock
CRM & Sales
Pipedrive, Monday.com, Salesforce, Zoho, HubSpot
Deals, pipelines, tasks, quotes, order status
No-Code & Automation
Softr, Bubble, Xano, n8n
App back-ends, workflow orchestration, internal tools
Data & Analytics
Chartmetric, OpenPlay, Luminate
Performance data, engagement metrics, reporting feeds
Productivity
Google Workspace, Airtable, EDI
Forms, sheets, docs, calendars, B2B document exchange
If your system isn't listed, it's almost certainly still integrable. We scope against your actual requirement, not a connector catalogue.
Systems We Integrate
A working list of the platforms currently in our integration practice. Every pairing is scoped to your specific workflow rather than a fixed template.

How Do We Integrate Different Systems?
Most integrations are built one of four ways: direct REST/API connections, webhooks for real-time events, scheduled file or batch transfers, and third-party iPaaS platforms that wrap these into pre-built connectors. The right choice depends on your systems, transaction volume, and how standard your requirement is.
| Approach | What it is | Best for | Watch out for |
|---|---|---|---|
| Direct API | Custom code calling each system's REST/GraphQL API | Non-standard workflows, high volumes, real-time needs | Requires ongoing maintenance as APIs change |
| Webhooks | Event-driven triggers pushed from one system to another | Instant sync on create/update events | Needs retry & failure handling built in |
| Scheduled batch | File exports or bulk API pulls on a timer | Large master-data syncs, legacy systems, EDI | Not real-time; timing conflicts need planning |
| iPaaS connectors | Pre-built templates on platforms like Make, n8n, or Celigo | Standard flows going live fast | Subscription cost forever; templates bend only so far |
| Custom middleware | Purpose-built orchestration using the methods above | Multi-system workflows, AI automation | Needs a partner who can maintain it (that's us) |
The truth most vendors won't tell you: a pre-built connector is genuinely the right answer for many standard requirements. We'll tell you when it is, help you choose and configure it, and only build custom when your requirement demands it.
How Much Does Integration Cost?
A typical integration costs between $2,500 and $25,000 to implement, depending on the approach. Templated iPaaS connectors sit at the low end plus a monthly platform subscription; fully custom builds sit at the high end with no recurring platform fee.
| Approach | Implementation | Ongoing |
|---|---|---|
| Templated iPaaS connector | $2,500 – $8,000 | $99 – $600/month platform subscription |
| iPaaS orchestration (Make, n8n) | $4,000 – $12,000 | $50 – $300/month platform + support retainer |
| Custom API build | $8,000 – $25,000+ | Support retainer only, no platform fee |
Three factors move the number most: how many entities you sync (customers, items, orders, invoices), whether flows are one-way or bi-directional, and how much transformation logic sits between the systems. We quote fixed prices after a scoping call, so you know the cost before we write a line of configuration.
How Long Does It Take?
The single biggest schedule risk isn't development — it's unclean master data in your source system, which is why data review is the first step of our process.
Templated integrations
Standard entity sets on a pre-built connector or iPaaS template, live fast.
Custom builds
Bespoke API work, scaled to entity count, systems involved, and testing depth.
What Does Our Integration Process Look Like?
Every engagement follows the same five stages — you get a fixed-price scope and a mapping sheet you sign off before we build.
Discover
We map your systems, entities, volumes, and the business outcome you need.
Map
We document every field, direction, transformation, and error rule before building.
Build
We implement on the chosen platform or codebase, in a sandbox against test data.
Test
We run real transaction scenarios end to end — failure cases, retries, duplicate handling.
Support
We monitor after go-live, with alerting, logging, and a named contact.
Consultant vs. Buying a Connector
A connector vendor can only sell you their connector. An independent consultant starts from your requirement and picks the tool afterwards — which matters most when your workflow doesn't match the template.
| Connector vendor | RethinkingWeb | |
|---|---|---|
| Recommends | Their product | Whatever fits, including their product |
| Non-standard requirements | Change requests or workarounds | Custom logic is the core offering |
| Pricing | Subscription, per-connector | Fixed-price project + optional retainer |
| When it breaks | Support ticket queue | Named engineer who built it |
| Multiple systems | One connector per pair | One orchestrated architecture |
One Team, Every System
We build and run integrations for companies across the US, UK, Australia, and India. Our team combines integration engineering with deep roots in the platforms on both sides of the sync: we're a WordPress and WooCommerce development agency, an official Twenty CRM partner, and we build AI automation on the Claude API.

Why Integrate with RethinkingWeb
Integration only pays off if it keeps running after go-live. These are the reasons companies hand us the connection between their systems — and keep us on to look after it.
Vendor-Neutral by Design
We don't sell a connector, so we have no reason to push one. We recommend the approach that fits your requirement — even when that means a product we don't earn a cent from.
Fixed Price Before We Build
You approve a signed mapping sheet and a fixed quote before a single field is configured. No open-ended hourly meters, no scope surprises mid-project.
A Named Engineer, Not a Queue
The person who built your integration is the person who answers when something changes. No ticket lottery, no re-explaining your setup to a new agent each time.
Official Twenty CRM Partner
We're a recognized Twenty CRM partner and a WordPress & WooCommerce development agency — so we know both sides of most syncs we build.
Proven Across Four Countries
We build and run integrations for businesses in the US, UK, Australia, and India, spanning ERP, ecommerce, no-code, and B2B distribution.
Rescue & Take-Over Specialists
A large share of our work is fixing abandoned custom builds and broken connectors. If your last integration failed, we've almost certainly seen your exact situation.
AI Automation on the Claude API
Beyond moving data, we build AI agents on the Claude API that act on your records — natural-language reporting, automated order handling, and smart routing.
Monitored After Go-Live
Every integration ships with logging, alerting, and retry handling, so a failed sync surfaces to us before it becomes a problem you have to chase down.

No. The list above reflects our current active work, not a fixed catalogue. If your system has an API or exports data, it's almost certainly integrable.
Yes, using webhooks or event triggers where the connected systems support them. Some flows, like large master-data syncs, run better on a schedule instead.
Most projects land between $2,500 and $25,000 depending on approach and entity count. See the cost table above for a full breakdown by method.
Templated integrations typically go live in 2 to 4 weeks. Custom, multi-system builds usually take 6 to 12 weeks depending on complexity and testing depth.
Yes. Rescue work is a large share of our practice: broken connectors, abandoned custom builds, and integrations that no longer match the business process.
Yes. We build AI agents on the Claude API that query and act on synced data: natural-language reporting, automated order handling, and intelligent routing.
