Salesforce Integration Services
Salesforce integration connects your CRM to the systems that run the rest of the business — ERP, ecommerce, accounting, and marketing automation. We build these as an independent consultancy: we don't resell MuleSoft or any single connector, so we recommend the approach that actually fits your requirement and your Salesforce edition.
What Is Salesforce Integration?
Salesforce integration is the process of exchanging data automatically between Salesforce and the other applications your business runs on, so records like accounts, contacts, opportunities, orders, and invoices stay consistent everywhere without manual re-entry. It's how a closed-won opportunity becomes a NetSuite sales order, how a QuickBooks payment lands back on the Salesforce account, and how a Shopify customer appears in your CRM the moment they buy.
Most Salesforce customers run an ERP, an accounting package, an ecommerce store, and a marketing platform alongside the CRM. Every one of those is a potential silo. Integration turns that stack into a single operating picture: sales sees fulfillment and payment status, finance sees the pipeline, and nobody re-keys the same customer into four systems. Done well, it removes hours of manual work each week and eliminates the copy-paste errors that quietly corrupt your reporting.
What Can You Integrate with Salesforce?
You can integrate Salesforce with almost any modern system that exposes an API. The categories we work with most are ERP, accounting, ecommerce, marketing automation, and data warehouses — usually with orders and invoices flowing in both directions.
Marketing Automation
Marketo, HubSpot, Pardot
Leads, campaigns, scoring, attribution, lifecycle status
Order-to-Cash
ERP + billing + payments
Quote-to-order, invoicing, payment status, revenue reporting
Data & Analytics
Snowflake, BigQuery, Power BI
Bulk extracts, warehouse sync, BI dashboards, AI automation
If your system isn't listed, it's almost certainly still integrable — if it has an API, Salesforce can talk to it. We scope against your actual requirement and your Salesforce edition, not a connector catalogue.
How Do You Integrate Salesforce with Other Systems?
Salesforce exposes one of the richest API surfaces of any platform: the REST API for real-time record operations, the SOAP API for contract-based enterprise tooling, Bulk API 2.0 for millions of records asynchronously, Platform Events and the Streaming API for real-time change notifications, and Apex for server-side logic and callouts. On top of these sit MuleSoft and other iPaaS connectors that wrap the APIs in pre-built templates. The right choice depends on your edition, data volumes, API limits, and how standard your requirement is.
| Approach | What it is | Best for | Watch out for |
|---|---|---|---|
| REST API | JSON API for real-time, record-level create/read/update | Web integrations, single-record sync, modern custom builds | Daily API call limits by edition; design for efficiency |
| Bulk API 2.0 | Asynchronous batch loading and extraction of large data sets | Migrations, nightly syncs, millions of records | Not real-time; jobs are queued and processed asynchronously |
| Platform Events | Event-driven pub/sub over the Streaming API | Real-time triggers, event-driven architectures, low-latency sync | Event allocations and delivery limits; needs a subscriber |
| MuleSoft / iPaaS | Pre-built connectors on MuleSoft, Boomi, Celigo, or Workato | Standard flows (ERP, accounting, ecommerce) going live fast | Licence cost forever; MuleSoft especially is enterprise-priced |
| Custom middleware | Purpose-built orchestration (Make, n8n, or code) using the APIs above | Non-standard requirements, 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 — even if that means MuleSoft or Celigo — and only build custom middleware when your requirement demands it.
How Much Does Salesforce Integration Cost?
A typical Salesforce integration costs between $3,000 and $30,000 to implement, depending on the approach. Templated iPaaS connectors sit at the low end plus a monthly platform subscription; fully custom API builds sit at the high end with no recurring platform fee.
| Approach | Implementation | Ongoing |
|---|---|---|
| Templated iPaaS connector (Celigo, Workato) | $3,000 – $9,000 | $100 – $800/month platform subscription |
| iPaaS orchestration (Make, n8n) | $5,000 – $15,000 | $50 – $400/month platform + support retainer |
| Custom REST / Bulk / Platform Events build | $10,000 – $30,000+ | Support retainer only, no platform fee |
Three factors move the number most: how many objects you sync (accounts, contacts, opportunities, orders, invoices), whether flows are one-way or bi-directional, and how much transformation and dedupe logic sits between the systems. Salesforce API limits also matter — a high-volume sync may need Bulk API 2.0 rather than per-record REST calls. We quote fixed prices after a scoping call, so you know the cost before we write a line of code.
How Long Does It Take?
The single biggest schedule risk isn't development — it's duplicate and unclean records in Salesforce, which is why data review is the first step of our process.
Templated integrations
Standard object sets on a pre-built connector or iPaaS template, live fast.
Custom builds
Bespoke REST / Bulk API / Platform Events work, scaled to object count 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 field-mapping sheet you sign off before we build.
Discover
We map your systems, objects, volumes, API limits, 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 Salesforce sandbox first.
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.
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 Salesforce and everything else — and keep us on to look after it.
Vendor-Neutral by Design
We don't resell MuleSoft or any single 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 CRM and the systems on both sides of the sync, not just one half.
Proven Across Four Countries
We build and run integrations for businesses in the US, UK, Australia, and India, spanning sales, ecommerce, and B2B distribution.
Rescue & Take-Over Specialists
A large share of our work is fixing abandoned custom builds and broken connectors — including integrations that hit Salesforce API limits. If your last one 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 Salesforce records — natural-language reporting, automated opportunity updates, and smart lead 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.
The Team on Both Sides of the Sync
We build and run Salesforce integrations for companies across the US, UK, Australia, and India. Our team pairs deep Salesforce API experience — REST, Bulk API 2.0, Platform Events, and Apex callouts — with hands-on knowledge of the systems on the other side 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.
Because we run a full integration practice, the same team also handles the connected system. We connect Salesforce to ERP with our SAP Business One and NetSuite integrations, to accounting with QuickBooks, and to storefronts with Shopify — so one partner owns the whole flow, not just the CRM half.
Frequently Asked Questions
Yes. Salesforce exposes a rich set of APIs including the REST API, SOAP API, Bulk API 2.0, Streaming API with Platform Events, and Apex for server-side logic. Most modern integrations are built on the REST and Bulk APIs.
The REST API is the default for real-time record-level operations and web integrations. The SOAP API is the older, contract-based interface still used by many enterprise tools. Bulk API 2.0 is built for loading or extracting millions of records asynchronously in batches.
Yes. Syncing Salesforce with an ERP or accounting system — NetSuite, SAP Business One, QuickBooks, or Xero — is one of our most common projects, keeping accounts, orders, invoices, and payment status aligned across both systems.
Yes. Platform Events and the Streaming API let Salesforce publish changes the moment they happen, so downstream systems react in near real time. Large data loads still run better on scheduled Bulk API jobs.
We work with MuleSoft and other iPaaS platforms when they fit, but we don't require them. For many requirements a lighter iPaaS or a custom middleware build is faster and far cheaper than a full MuleSoft licence.
Yes. Shopify, WooCommerce, Magento, and BigCommerce all integrate with Salesforce, syncing customers, orders, and fulfillment status so sales and service teams see the full commerce picture.
Most projects land between $3,000 and $30,000 depending on approach, object count, and whether flows are one-way or bi-directional. See the cost table above for a full breakdown by method.
Yes. Rescue work is a large share of our practice: failed connectors, abandoned custom builds, hitting API limits, and integrations that no longer match the business process.
Yes. We build AI agents on the Claude API that query and act on Salesforce data: natural-language reporting, automated opportunity updates, intelligent lead routing, and case triage.
