Legacy System Integration

You don't need to rip out your existing systems. You need a layer that reads them, connects them, and surfaces what matters — without another implementation project.

A Spaid engineer connects to your existing FSM and telephony systems via API, builds a unified intelligence layer on top, and delivers operational insight without a migration, a new platform, or an IT project.

The Legacy System Problem

What legacy systems cost you — and why replacing them isn't the answer.

Most field service operators considering a system replacement are solving the wrong problem. The issue isn't that their FSM is too old — it's that their FSM data has never been analyzed in a way that produces actionable insight. The fix is a connection layer, not a replacement project.

ServiceTitan migration costs typically run $150K–$400K and take 6–12 months — not including retraining and productivity loss during the switch. Operators moving from Service Fusion, FieldEdge, or older on-premise systems face the same tradeoff: pay for a platform upgrade that doesn’t guarantee the data gets analyzed, or add an intelligence layer to the system you already have. Most field service software modernization projects solve the platform problem. They don’t solve the data problem. For operators dealing with disconnected tools across the stack, see also: connecting your existing systems without a migration.

Migration Risk and Cost

A full FSM migration typically costs $150K–$400K in implementation fees, 6–12 months of operational disruption, and a significant productivity loss during transition. For operators who choose to stay on their current system, the data problem remains unsolved. For those who migrate, the same data problem reappears in the new system.

Average FSM migration costs $150K–$400K and 6–12 months

The Data That Never Gets Used

ServiceTitan, FieldEdge, Jobber, and Service Fusion all contain years of job records, invoice history, dispatch data, and pricebook information. Almost none of it has ever been analyzed in a structured way. The value is in the data, not the platform — and the data to find revenue leaks is already in your existing system.

Less than 10% of FSM historical data is actively analyzed

Integration as a Never-Ending Project

Every time you add a tool — call tracking, CRM, membership platform — someone needs to connect it to the FSM. Each connection is a manual export, a webhook configuration, or an IT project. The integration backlog grows, the data gaps persist.

Why Existing Solutions Fail

Replacement project vs. a connection layer.

A replacement project solves the wrong problem. A connection layer reads your existing systems, connects them, and surfaces what matters — without disrupting the workflow your team has built around your current tools.

What you've tried before

FSM migration to modern platform

6–12 months of disruption, $150K–$400K in fees, retraining your entire team. Solves the platform problem. Doesn't guarantee your data gets analyzed.

Custom integration development

IT project, developer hours, ongoing maintenance. Takes 3–6 months to build and breaks when the source system updates.

Manual exports and spreadsheet analysis

Monthly at best. Already stale. Requires an analyst to interpret. Misses in-month patterns.

Point tools that read one system

Each tool connects to the FSM alone. None of them connect to each other. The silo problem multiplies.

VS
What forward-deployed looks like

FSM API connector works with your existing system — no migration required

Reads ServiceTitan, HCP, FieldEdge, Jobber, or Service Fusion via API. No replacement, no migration, no retraining. Connection established in 72 hours.

Call recording integration connects to existing telephony

Connects to CallRail, RingCentral, ServiceTitan Phones Pro via API. No new telephony system required.

Intelligence layer built on top of legacy systems

Unified operational view sits on top of your existing stack — no migration, no training, no change to existing workflows.

Engineer on-site handles integration setup

No IT project, no vendor coordination. The Spaid engineer establishes all API connections and validates data flow during the first week of the engagement.

Engineer + Software

How the engineer and software connect your existing systems.

Connection established in 72 hours. No migration. No IT project.

FSM API Connector

Reads your existing system without replacing it

Connects to ServiceTitan, HCP, FieldEdge, Jobber, or Service Fusion via API. Reads job records, invoice history, dispatch data, pricebook, and membership information. No migration, no re-implementation. Connection established in the first 72 hours. Your team keeps using the same FSM they know.

Call Recording Integration

Telephony connected to your existing FSM data

Integrates with CallRail, RingCentral, ServiceTitan Phones Pro, or other telephony systems via API. Maps call outcomes — answered, booked, objection handled, follow-up triggered — to job records in your FSM. Cross-system patterns surfaced without any change to your current call system.

Unified Intelligence Layer

Operational insight on top of legacy systems

A unified view built from all connected data sources — no migration, no new platform, no training required. Patterns that require cross-system context are surfaced automatically. The intelligence layer works with your existing stack, not instead of it.

On-Site Engineer Integration Setup

No IT project, no vendor coordination

The Spaid engineer establishes all API connections, validates data flow, and resolves integration issues during the first week of the engagement. No IT ticket, no vendor call, no months-long integration project. Connection to full operational data is live before Week 1 ends.

The Measured Pilot Guarantee

If we don't identify $200K, you pay nothing.

Our Full-Operation Audit (Days 1–30) maps every revenue leak — field and back of house. If we don't identify at least $200,000 in recoverable annual revenue, we refund Phase 1 in full. You keep all audit deliverables.

After kickoff, we ask for about 30 minutes a week of your ops leader's time.

Zero risk. Full-operation visibility. Founding customer pricing: 40% below standard rates.
Start Here

45 minutes. Your data.
No commitment.

We'll start with a recent export or sample call data from your FSM and call system, show you the biggest leaks, and scope the engagement. Full access happens only if you proceed to the audit.
