Simpro integrations and custom connectors.
What Simpro connects to out of the box, what the Marketplace adds, and what to do when neither fits. We build the custom connectors: accounting and ERP systems the standard links do not cover, CRM, payroll, vehicle tracking, calendars and your own in-house software.

Three ways to connect Simpro, in the order you should try them.
Simpro holds your quotes, jobs, schedules, stock and invoices. The accounts, payroll, CRM, vehicle tracking and calendars usually live elsewhere, and the question is how to make them share data without someone re-typing it. There are three routes, and the right one is the cheapest that does the job.
First, Simpro's standard links. Simpro provides its own accounting links for Xero, QuickBooks Online and MYOB, set up inside your build. Second, the Simpro Marketplace, which lists more than 200 integrations from Simpro's partners, including payroll apps such as Employment Hero and Xero Payroll, supplier and wholesaler connections, safety and compliance tools, Power BI connectors and a Zapier app. Third, a custom connector built on the Simpro API and webhooks, for everything the first two do not cover.
We build the third kind, and we will tell you when you only need the first or second. Our Simpro experience is hands-on: we have built Simpro integrations and customisations as the development team behind a UK Simpro partner firm.
What connects to Simpro, and how.
A short guide by type of system. Standard connectors change over time, so confirm the details on Simpro's Marketplace or with Simpro support before you rely on one.
Accounting: Xero, QuickBooks and MYOB
Use Simpro's standard accounting link if you run Xero, QuickBooks Online or MYOB and your setup is conventional. Go custom when you have several entities or an unusual chart of accounts, when you use a package without a standard link, such as Sage, Microsoft Dynamics, NetSuite or Odoo, or when finance needs rules and checks the standard link does not offer.
Payroll and timesheets
Check the Marketplace for your payroll provider first. A custom connector is worth it when your pay, allowance and overtime rules are applied by hand today, when payroll runs in a system with no listing, or when timesheets should be checked against vehicle tracking before they are paid.
CRM, website forms and calendars
Website enquiries and CRM deals can create Simpro leads, customers and quotes, with status sent back as the job progresses. Calendar sync with Google Calendar or Outlook is available through third-party connectors; a custom build makes sense when you need rules about which bookings appear, for whom, and what happens when either side changes.
In-house systems, suppliers and reporting
Your own ERP or database, supplier price files, customer portals and data warehouses have no off-the-shelf connector by definition. These are built on the Simpro API, with webhooks to react to changes, and a reporting database if you want Power BI or dashboards across several systems.
How we decide and build a Simpro connector.
Four steps. The first one often ends with us telling you a standard connector is enough.
Check the standard routes
We look at what you need to move and whether Simpro's own link or a Marketplace app already does it. If one does, we say so and you can stop here.
Map the data and the owner
For a custom build we list every field that moves, decide which system is the source of truth for each record, and write down what happens when the two disagree.
Build and run in parallel
We build against a test company and the other system's test environment, then run the connector alongside your current process and reconcile its output before switching over.
Hand over with monitoring
You get the running connector, alerts, a failure review queue, field mapping documentation and a runbook. Support and changes are available on an agreed scope.
Custom Simpro connectors we build.
Each one is built through the Simpro REST API and webhooks, against your own build and your own rules.
Accounting and ERP
Invoices, credit notes, supplier invoices, payments and cost centres synced with packages the standard links do not cover, or with entity and account structures they cannot map.
Payroll and timesheets
Simpro timesheets into payroll with your pay rules applied, including a check against vehicle tracking before hours are paid.
CRM and lead capture
Website forms and CRM deals turned into Simpro leads, customers, sites and quotes, matched against existing records first.
Vehicle tracking
Arrival and departure times from your tracking system compared with Simpro timesheets and schedules, with differences flagged for a manager.
Suppliers and catalogues
Supplier price files loaded into your Simpro catalogue on a schedule, and purchase orders sent to suppliers that can receive them.
Reporting and data warehouse
Simpro data loaded into a database you own, alongside accounting and CRM data, ready for Power BI or custom dashboards.
AI assistants
An MCP server that lets an AI assistant answer questions from your Simpro data, read-only by default, scoped to the access you choose.
Why Simpro businesses and partners work with Moweb.
An offshore team is a fair thing to question. Here is what you get and how we protect your data.
Real Simpro work behind us
Our developers have shipped Simpro integrations for a UK Simpro partner firm's end clients, so per-build API hosts, company-level resources and the shared rate limit are familiar ground.
The cheapest route that works
If a standard link or a Marketplace app does what you need, we will tell you and point you to it. A subscription costs less than a build, and we would sooner say so on the first call.
Certified security and process
Moweb is ISO 27001:2022 certified and CMMI Level 3 appraised. API credentials are stored encrypted, scoped to what the integration needs, and never shared outside the project.
Careful with your API limit
Simpro allows 10 API requests per second per build, shared by every integration on it. Our connectors queue, batch and back off, so a busy sync does not disturb your other connected apps.
Systems we are asked to connect to Simpro.
Signs a standard connector is not enough.
You are probably fine on a standard connector if records flow one way, your setup is typical for your accounting or payroll package, and nobody is fixing the output by hand afterwards. Most Simpro businesses start here, and many never need more.
The signs that you have outgrown it are practical ones: someone exports a spreadsheet every week to correct what the connector did; records duplicate or fail and nobody is told; you need data to flow both ways with rules about which system wins; you run several entities or companies; or the other system simply has no connector. Those are the cases a custom connector is built for.
Built with the right tools.

Questions about Simpro Integrations.
What teams ask before they start.
Simpro provides its own standard accounting links for Xero, QuickBooks Online and MYOB, which you set up inside your Simpro build to pass invoices, payments and related records to your accounts. For most businesses with a conventional setup that link is the right choice. A custom connector is for cases it does not fit, such as several entities, an unusual chart of accounts or extra checks finance needs.
