Embedded Integration Layer Retainer Build (10-18 days)
A productized engagement that stands up a white-labeled, multi-tenant integration layer inside a client's product or back office, then hands it over as a managed retainer. The offer turns one-off connector work into recurring middleware revenue for the agency.
- A signed scope naming the systems in play and the data objects that must move between them; read access to each source system's API documentation or sandbox; a named client-side technical owner who can approve schema changes; a decision on whether the integration layer is embedded in the client's product or run as an internal back-office hub; a written data-handling note covering credentials, PII fields, and retention.
- 1.Inventory every system in scope and label each as source, destination, or both
- 2.Map the three highest-volume data objects and their current manual handoffs
- 3.Confirm the client-side approver for schema and credential changes
- 1.Score each system by API maturity, auth model, and rate limits
- 2.Flag systems with no native API and note the webhook or file-drop fallback
- 3.Rank integration candidates by hours saved per week
- 1.Draft the canonical field mapping for the first data object
- 2.Define conflict rules for records edited in two systems at once
- 3.Agree on sync direction and cadence with the client owner
- 1.Stand up the chosen platform workspace and separate client environments
- 2.Connect the first two systems in a sandbox tenant
- 3.Log every credential in the client's vault, not the agency's
- 1.Build the first end-to-end flow and run a single-record test
- 2.Capture the raw payload on both sides for comparison
- 3.Fix field-type mismatches before scaling volume
- 1.Add error handling and a retry path for failed records
- 2.Route failures to a shared alert channel the client can see
- 3.Document the rollback step for each flow
- 1.Run a backfill of historical records into the destination system
- 2.Reconcile counts and spot-check twenty records by hand
- 3.Record the reconciliation result in the project log
- 1.Apply the client's brand to the embedded or shared interface
- 2.Restrict end-user permissions by role
- 3.Test the experience as a client-side end user, not an admin
- 1.Load-test the flow at twice expected peak volume
- 2.Measure sync latency and record the baseline number
- 3.Tune batch sizes where latency exceeds the agreed threshold
- 1.Write the runbook covering every flow, owner, and failure mode
- 2.Record a short walkthrough video for the client's team
- 3.Hand over admin access and confirm the client can log in
- 1.Run a live monitoring window with the client watching
- 2.Resolve any alerts raised during the window
- 3.Agree the monthly health-check cadence for the retainer
- 1.Present the hours-saved baseline and the retainer scope
- 2.Confirm the support boundary: what is covered and what is billed separately
- 3.Schedule the first monthly review before the kickoff call ends
The build fee covers discovery, mapping, and the first two or three flows, but the real margin sits in the retainer: monitoring, schema drift, and new connector requests recur every month and are priced against the client's cost of a full-time integration hire. Because the agency owns the mapping logic and the runbook, switching costs stay high, and the client rarely has an internal team that can absorb the work. Margin erodes only when the agency lets the client's product team take over connector maintenance, so the retainer should always include a named owner on the agency side.
- System inventory with API maturity scores and integration priority ranking
- Canonical field mapping document for each in-scope data object
- Configured integration workspace with branded end-user interface and role permissions
- Operations runbook covering flows, owners, failure modes, and rollback steps
- Monthly health-check template with latency, error-rate, and hours-saved tracking
The client's team runs the integration layer for five consecutive business days without agency intervention, and the monthly health-check report shows zero unresolved sync failures.
