Every CE practice has a version of the same story.

The proposal goes out. Scope is defined. The data migration is in there: extract, transform, load, validate. Duplicate detection is in there too, at least implicitly. The client assumes clean data on day one. The practice assumes the standard workaround will hold.

Go-live week arrives. The workaround takes longer than estimated. A plugin needs adjusting for a custom entity nobody scoped. The bulk cleanup job hits the 5,000-record ceiling and has to be batched manually. The consultant who built the original workaround is now splitting time between this project and the next one.

The project closes. The client signs off. The duplicate workstream absorbed six hours more than estimated. On a fixed-fee engagement, those six hours came out of margin.

Multiply that across a year of migrations, and the duplicate workstream stops being a project inconvenience and starts being a line item that nobody is tracking.

What “a year of migrations” looks like for a boutique CE practice

Disclaimer: The figures below are illustrative estimates based on typical boutique CE profiles. Your numbers will vary depending on project size, team composition, and how your practice scopes data migration work.

A boutique CE practice running five to eight migrations per year isn’t unusual. Mid-market clients, D365 CE implementations, full delivery cycle, including data migration. Each project scoped at a fixed fee, delivered by a team of two or three consultants.

On each of those projects, the duplicate workstream involves some combination of:

• Configuring or extending a custom plugin for the entities in scope
• Setting detection headers on one or more integration connectors
• Running and batching a post-migration bulk detection job
• Investigating and merging duplicates that got through
• Handling go-live escalations when the client finds duplicates in the first week

Conservatively, that’s eight to twelve hours per project when the workaround behaves as expected. When it doesn’t, a new integration connector, a custom entity that wasn’t in the plugin scope, a larger-than-expected dataset, the hours climb.

At eight projects per year, the low end is 64 hours. The high end, on projects where something unexpected surfaces, is closer to 120.

The hours that don’t make it onto the timesheet

The 64-to-120-hour range only captures the work that gets logged. There’s a second category that doesn’t.

Tribal knowledge transfer. The consultant who built the workaround on project one has context that isn’t documented anywhere. When a new consultant joins Project Four, someone has to get them up to speed. That handoff takes time, and it happens informally: a Slack message, a call, a quick walkthrough. It doesn’t go on a timesheet. It comes out of someone’s afternoon.

Go-live firefighting. When duplicates surface at go-live, the response is rarely calm and methodical. It’s the consultant who owns the data workstream, on a call with the client, pulling up the environment and diagnosing in real time. That hour or two isn’t pre-scoped. It’s absorbed.

Post go-live cleanup requests. Clients find duplicates after sign-off. They raise a support ticket, or they call the practice lead directly. The practice decides whether to treat it as a warranty item or bill for it. Either way, someone is doing the work.

Add those categories together, and the annual cost of the dedupe workaround starts to look less like a rounding error and more like a mid-level consultant’s monthly capacity.

The fixed-fee problem

Time-and-materials engagements can absorb overruns. Fixed-fee engagements can’t, at least not without a conversation about scope.

Most boutique CE practices run fixed fees. It’s what clients want, and it’s what differentiates a practice that knows its delivery well from one that doesn’t. The risk of a fixed-fee model is that every unscoped hour comes directly off the bottom line.

The duplicate workstream is almost always underscoped. Not because practice leads are careless, but because the workaround behaves differently on every project. The entity model is different. The integration connectors are different. The dataset size is different. The same workaround that took four hours on the last project takes ten on this one, and there’s no reliable way to predict which it’ll be at proposal time.

The result is a cost that gets absorbed rather than billed, repeated across every engagement, and never quite large enough on any single project to force a conversation about it.

What the cumulative number looks like

Using a conservative billing rate of $100 per hour, low for a senior consultant at a boutique practice, and a mid-range estimate of 10 unscoped hours per project:

• 5 projects per year: $5,000 absorbed annually in unscoped duplicate work
• 8 projects per year: $8,000
• 10 projects per year: $10,000

These aren’t dramatic numbers in isolation. But they represent margin that was earned and then given back on work that doesn’t differentiate the practice, doesn’t build client relationships, and doesn’t make the next project any easier.

The number also compounds. A practice running eight migrations per year for three years has absorbed somewhere between $20,000 and $30,000 in duplicate workstream overruns, conservatively, without a single internal conversation about whether there’s a better way to handle it.

The opportunity cost nobody calculates

The hours absorbed by the dedupe workaround have a second cost that doesn’t show up in any margin analysis: what those hours could have been used for instead.

A senior consultant spending ten hours on duplicate cleanup is ten hours not spent on configuration work, business process design, or client-facing delivery that the client notices and remembers. It’s ten hours not spent on the next project, or on internal practice development, or on the kind of work that generates referrals.

The dedupe workaround is infrastructure work. Infrastructure should be invisible, configured once, running in the background, not requiring a consultant’s attention on every engagement. When infrastructure work consumes senior consulting hours on every project, the practice is subsidizing a problem that has a solved alternative.

What changes when you treat it as infrastructure

The practices that have moved away from the per-project workaround typically describe the same shift: the duplicate workstream goes from a variable cost to a fixed, predictable one.

A native Dataverse deduplication layer, installed from Microsoft Marketplace, configured once per client environment, covers all entry points without per-integration setup. Standard and custom tables are included. There’s no 5,000-record ceiling on bulk jobs. The configuration is consistent across engagements rather than being rebuilt from scratch each time.

Plauti Deduplicate for Dynamics 365 CE works that way. It installs inside the client’s Dataverse environment, runs without external dependencies, and handles duplicates at every entry point from day one of go-live. For a practice running five or more migrations per year, the annual licensing cost is typically recovered within the first one or two projects where the workaround would otherwise have overrun.

The margin doesn’t disappear; it stays where it was earned.

A useful question for the next project kickoff

Before the next migration gets scoped, it’s worth asking one question internally: how many hours did we absorb on the duplicate workstream on the last three projects, and what did we estimate?

If the answer is “we don’t track that separately,” that’s the first thing worth changing. The cost is there; it’s just not visible yet.

If you want to see how other CE practices have restructured this part of their delivery stack, book a 20-minute walkthrough with the Plauti team. The conversation is worth having before the next proposal goes out.
