We helped a 14-person sales team migrate off HubSpot last quarter. The total cost we initially estimated: about $4,000 in implementation time. The actual cost: closer to $11,000. Here is where the gap was.
This is not a hit piece on HubSpot. It is a fair product. The point of writing this is that when a vendor or a switching-guide blog quotes you a number for migrating, they are usually quoting you the cost of importing the data, which is the smallest line item. The real costs are downstream.
The four line items nobody tells you about
1. Workflow rebuild: 30-60 hours of operator time
HubSpot workflows are a big part of the product's value. They are also nearly impossible to export to another system cleanly. The migration tool will bring contacts, deals, and notes. It will not bring the 23 workflows your previous ops person built three years ago.
In our case, we spent about 35 hours documenting what each workflow did, deciding which ones were still relevant, and rebuilding them. We discovered that about 40% were redundant, dead, or solving a problem we had since solved differently. That part was useful. The other 60% needed proper rebuilding.
Budget: $80-150 per hour of an internal ops person, or $150-250 per hour of an outside consultant. For 35 hours that is $2,800-8,750.
2. Sequence and template re-creation: 10-20 hours
Email sequences, snippets, and templates do not migrate. They live in HubSpot's format and the new tool wants its own format. In practice this means a copy-paste exercise plus regression-testing each sequence to make sure tokens work.
We had 11 active sequences and 40-odd templates. Two reps spent two and a half days each on this. About 35 hours total.
3. Reporting re-builds: easy to underestimate
Every saved dashboard and report needs to be rebuilt in the new tool. The migration brings the underlying data. It does not bring the reports.
In our case we had 17 reports that someone looked at weekly. Six of them turned out to be duplicates of each other. The remaining 11 took roughly 30 minutes each to rebuild and validate against historical numbers, which is necessary because if the new report disagrees with the old one, the sales team will not trust it.
Budget: 5-10 hours.
4. Re-training: the cost nobody quotes
People are slower in any new tool for 4-8 weeks. They click in the wrong places. They cannot find the export button. They build deals incorrectly and have to redo them.
If you have a 14-person team and each person loses 30 minutes per day to slower workflows for 6 weeks, that is 105 hours. At a notional internal cost of $50/hour, $5,250. This is the line item that does not appear in any switching guide.
The good news: people adjust. By week 8 the time loss has flattened. By week 12 you usually have measurable productivity gains over the old system because you removed the workflows you were no longer using.
What we should have done differently
Three things, in priority order.
Run both systems in parallel for 30 days
We did a hard cutover. Tuesday on the old system, Wednesday on the new. The reason: the data export was clean and we did not want sync conflicts. The cost: when we found gaps in the migration on day 5, we had to scramble to fix them in production.
Next time: run parallel for 30 days, even at double cost. Decommission only after a full month of clean reporting on the new system.
Document workflows before importing data
We started rebuilding workflows after the data was in. This meant reps were using the new system without the automations they were used to. Sales activity dropped about 15% in the first two weeks because the safety net was not there.
Next time: spend a week documenting every active workflow before touching the data. Rebuild the top 10 by usage in the new system on a sandbox before cutover.
Budget 2.5x what the vendor quotes
If a vendor or a migration partner tells you the project is X dollars, budget 2.5X. Some of it is genuine scope creep. Some of it is the time costs above. The companies that switch CRMs and are happy 12 months later are the ones who budgeted realistically and did not start cutting corners halfway through.
Why we still recommended the switch
Despite all of the above, the team has been on the new CRM for 6 months and would not go back. The monthly bill dropped from $1,850/month (HubSpot Sales Hub Pro for 14 seats with Marketing Hub Starter) to under $600/month. At that delta, the switching cost paid back in roughly 9 months.
The point of writing this is not to scare you off switching. It is to budget honestly. If the math still works at 2.5x the vendor's quoted cost, you should probably switch. If it does not, you should stay.
The actual question to ask: "What does this cost me, fully loaded, over 18 months including disruption?" If that number is below your current annual spend by a meaningful margin, switch. If it is borderline, stay and revisit when your contract renews.
