Custom Integrations Between Systems
Need an integration between systems? CRM Connector builds custom API integrations between CRMs, finance tools, booking systems, databases, portals, and other API-connected platforms.
Projects can be scoped as one-way syncs, two-way syncs, migrations, middleware, hosted API bridges, or internal tooling, with feasibility-first scoping, contract delivery, and static pricing where scope is clear.
Delivered by a full-time engineer
Built by CRM Connector with recent hands-on delivery across CRM, finance, booking, and operations systems.
Feasibility first, then scope
First confirm the workflow, API access, and delivery shape, then scope the project with contract terms and pricing where it is estimable.
Hosting and handover options
Projects can be hosted on our side, with handover or source code delivery planned into the scope when needed.

Integration patterns
One-way syncs, two-way syncs, and deeper system work
One-way syncs
Move data from one system into another cleanly and reliably.
Two-way syncs
Keep records aligned in both directions when the systems allow it.
Hosted and database-backed workflows
Some projects need middleware, databases, hosting, or internal tooling around the integration.
Project process
How a custom integration project usually runs
A serious integration project usually needs feasibility, scope, implementation, testing, and a clean launch path.
Discovery and feasibility
Start with the systems involved, the workflow problem, and whether the APIs, webhooks, or data model support the result you want.
Scope and pricing
Define the sync direction, fields, edge cases, ownership, and delivery scope so the work can be quoted clearly.
Build and test
Implement the integration, test the important flows, and make sure the data moves reliably before launch.
Launch and continuity
Go live with hosting, handover, source-code delivery, or follow-up support planned into the agreement where needed.
Good fit
Projects usually work best when these pieces are clear
API-connected systems
Best fit for platforms with APIs, webhooks, or structured exports that can support reliable integration work.
Clear business workflow
Strongest projects start with a defined problem like syncing customers, invoices, jobs, bookings, or admin data.
Need reliable delivery
Good fit when you want scoped implementation, testing, and a cleaner result than manual CSV or no-code patchwork.
Need hosting or handover
Projects can be hosted, handed over, or documented for continuity depending on how your business wants to own the result.
What can be built
Common custom project scopes
CRM syncing
Connect CRMs and internal systems with the right field mapping and sync rules.
Finance integrations
Connect billing, payment, and finance tools when transaction data needs to move.
Operational integrations
Keep booking, quoting, job, and back-office systems aligned.
Migrations
Move data between platforms with cleaner structure than manual CSV workflows.
Middleware and portals
Build the glue between APIs, databases, dashboards, and business apps.
Example systems
Clean examples of custom integration work
Example project scopes can be built around systems like Jobber, QuickBooks, Square, and Xero, but the same approach can be scoped for almost any API-connected platform.
Jobber
Sync leads, customer updates, and completed-job signals into CRM follow-up, reporting, or internal workflows.
QuickBooks
Move invoice and payment data into CRM automations, sales dashboards, or finance visibility workflows.
Square
Route customer, order, and payment events into marketing, support, or downstream operations systems.
Xero
Connect accounting and contact records with sales systems, admin portals, or database-backed business processes.
ServiceM8
Sync job, customer, and workflow data into CRM follow-up, scheduling, or internal reporting systems.
Housecall Pro
Route customers, bookings, and field-service updates into sales pipelines, support workflows, or admin tooling.
Vagaro
Connect appointment and customer activity with marketing automations, reporting, or back-office systems.
Dentally
Move patient, booking, or operational data into CRM workflows, admin dashboards, or connected internal processes.
Not limited to these logos
If your stack is different, the same integration process can be scoped for almost any system with an API.
