03 / MIDDLEWARE & CUSTOM INTEGRATIONS
Make the systems behind your business work together.
Design, build, and maintain middleware that connects your business tools to your field service software, with defined ownership, permitted access, and clear recovery steps.
THE WORK IN PRACTICE
Define the outcome.
Account for the details.
Middleware is the software that coordinates a handoff between systems. It can receive a booking request, match a customer and location, validate the required fields, and send the agreed action through a supported API. We map those steps around your office process, then build and maintain the agreed connection. Feasibility depends on each vendor’s capabilities, account entitlements, and required approvals.
Where this fits
Useful when a specific handoff requires custom logic and your organization can provide an accountable system owner, supported access, and staff for acceptance testing.
A CONCRETE HANDOFF
What you get.
Deliverables are selected and confirmed in a written scope of work.
Our integration model- A workflow and feasibility assessment identifying source records, destinations, supported interfaces, permissions, vendor dependencies, and exceptions.
- Developer portal registration guidance where the vendor supports it; the client registers and manages the application and credentials.
- A client-managed access inventory covering app ownership, permissions, credential storage location, rotation, and revocation—without copying secret values into project documentation.
- A field map and scoped middleware build in the agreed hosting environment, including customer and location matching where supported, validation, duplicate handling, and failure recovery.
- Acceptance scenarios covering successful transfers, incomplete records, retries, access failures, and manual recovery.
- Written IP, hosting, and configuration handoff terms, plus operating instructions identifying ownership and ongoing responsibilities.
- An optional monitoring and maintenance scope defining alerts, support hours, response targets, vendor-change review, and separately scoped additions.
PLANNING THE ENGAGEMENT
A typical project shape.
Vendor approvals, multiple systems, limited test environments, or complex record matching can extend the schedule. Implementation begins after the required access path is confirmed.
Discover and confirm access
Map the workflow, check supported capabilities and account requirements, and agree on acceptance criteria. Vendor approvals may introduce additional waiting time.
Build and review
Configure the agreed runtime, implement field mapping and exception handling, and review sample transfers with the client system owner.
Validate and hand over
Complete client acceptance testing, document hosting and configuration, and confirm the launch and any optional support scope.
These are illustrative planning ranges, not delivery commitments or claims about past engagements. We confirm timing after reviewing scope, access, vendor requirements, data quality, and testing dependencies.
PRACTICAL QUESTIONS
Before we start.
An app registration identifies an application and its permitted access. Middleware is the running software behind the connection: it receives requests, applies mapping and validation rules, calls supported interfaces, and handles the outcome. Registering an app alone does not provide that runtime or establish permission for every downstream connection.
The client creates, stores, rotates, and revokes credentials. Tack does not hold client credentials. Access configuration and the credential lifecycle are documented within the agreed client-controlled environment.
The project agreement identifies ownership of the code, hosting account, configuration, documentation, and handoff rights. Hosting may be client-managed or provided under a separate hosting arrangement where vendor requirements permit. We record who administers the runtime, how access is revoked, and how the agreed work can be transferred.
Only when monitoring is included in a defined support scope. That scope identifies alert recipients, support hours, response targets, and exclusions. A completed build does not imply continuous supervision or guaranteed uptime.
No. The actual application, runtime, access path, and data recipients must meet vendor requirements. Registering an app in a customer’s name does not permit uncontrolled third-party access or use across other customers. We confirm the supported path before implementation.
