Post Merger Integration Checklist for a Text(255) Field

Post Merger Integration Checklist for a Text(255) Field

On a multi-location healthcare marketing client, the mapping was right. The field was Text(255). Six answered calls created no Lead. That miss belongs on a post merger integration checklist.

What belongs on a post merger integration checklist for CRM and attribution data? A post merger integration checklist for CRM and attribution data is basically 4 things. Check field lengths against real ad URLs, not samples. Keep Text(255) off the mapping until the field is Long Text. Drop only the line the CRM rejects. Backfill calls that created no Lead, and skip one that already matches a quote lead marked New Patient.

A post merger integration checklist is the ordered list of systems, data, access, and validation checks a buyer runs so two companies can operate as one platform.

This check belongs on a technology due diligence consulting file. The hub above this page is post-merger integration for mid-market PE portcos. The two pages beside it are post merger integration challenges in the first 100 days and application rationalization during M&A.

What was the mapping for?

Last Click mapping was saved to stop call leads showing as "Unknown". Ad landing pages carry click IDs and UTMs, so many are longer than 255 characters.

What did the CRM reject?

Starting 4:51 PM CT on 4 Nov, the CRM rejected answered calls with "Last Click Landing Page: data value too large (max length=255)". Six answered calls created no Lead.

The mapping was right. The field was Text(255). Our call tracker had the answered calls. The CRM did not create the Lead.

What was the same-day fix?

Same-day fix: remove only the landing_page_url mapping line, keep the other Last Click fields, and widen the landing-page fields to Long Text before putting the line back.

When did calls create Leads again?

By evening 5 Nov, calls were creating Leads again. Lead Source lands as "Website - Phone Call".

What did we backfill?

The seven calls lost while the line was live were backfilled. Six as the call tracker would have. One was skipped because it matched an existing quote lead already marked New Patient.

Was this a merger?

No. This was a CRM mapping change, not an acquisition. I am not going to dress a field fix up as a close.

The failure is still the one that shows up when an acquirer folds a portfolio company's call tracking and attribution into the platform CRM. The landing page URL does not get shorter because the mapping was written after a signing. A post merger integration checklist that skips field lengths and validation rules, and tests them on sample URLs, will miss it the same way.

What does a post merger integration checklist check, and when?

1. Before you map. Check field lengths against real ad URLs, not sample ones. Ad landing pages carry click IDs and UTMs, so many are longer than 255 characters. A Text(255) field will not hold them. Map attribution fields in production only after that check.
2. When the CRM rejects the row. If the error is "Last Click Landing Page: data value too large (max length=255)", remove only the landing_page_url mapping line. Keep the other Last Click fields.
3. Before you restore the line. Widen the landing-page fields to Long Text. Then put the landing_page_url line back.
4. After calls create Leads again. Confirm Lead Source lands as "Website - Phone Call". Backfill the calls lost while the line was live. On this file, seven calls were backfilled, six as the call tracker would have, and one was skipped because it matched an existing quote lead already marked New Patient.

What did we decide?

After the fire drill, the decision was plain. Map attribution fields in production only after checking field lengths against real ad URLs, not sample ones.

Why does a buyer ask about call volume?

Call attribution is becoming a diligence question, not just a marketing one.

There is no secret. Here is what we actually ran. We took one mapping line off the same day. We kept the other Last Click fields. We widened the landing-page fields to Long Text before that line went back. By evening 5 Nov, calls were creating Leads again.

A PE-backed multi-location operator will ask why call volume in the CRM does not match the call tracker. The answer can be a validation error. The row never became a Lead, so the CRM looks quiet while the call tracker looks fine.

That question belongs on the technology due diligence consulting read, in the same file as whether the data model can hold the plan. The operating model for the combination stays on the post-merger integration hub. Sequencing the first 100 days stays on post merger integration challenges. Which system survives stays on application rationalization during M&A.

Don't trust a mapping that looks right on a sample URL. Check the field length against a real ad URL before that line goes to production.

If call tracking is about to land in the platform CRM, which attribution field is still Text(255), and which real ad URL did you try to write into it?

If that line is missing from the post merger integration checklist, talk to us.
