The Replacement Map
35% of teams have already replaced at least one SaaS tool with a custom build. 78% plan to do more this year. But the first question everyone asks is: where do I start?
Not all SaaS categories are equally ripe for replacement. Some are bloated, overpriced, and barely used. Others are genuinely complex and worth paying for — at least for now.
This is the map. Seven categories, ranked by replacement pressure, with real cost data, build timelines, and ROI examples. Use it to decide which subscriptions to cancel first and which to leave alone.
If you want the broader strategy behind the replace-vs-buy decision, start with our Complete Guide to SaaS Replacement. This post is the tactical companion — category by category, dollar by dollar.
How to Read This Guide
For each category, we cover:
Let's start with the most expensive offender.
1. CRM & Sales Tools
Replacement Pressure: 25%
What You're Paying
Salesforce dominates this category, and the pricing tells the story:
A 200-person sales organization on Enterprise tier pays $396,000/year. On Unlimited+, that's $1.2 million/year. For a CRM.
HubSpot looks cheaper upfront but the Enterprise tier runs $150/user/month once you add the features that actually matter. Pipedrive and Zoho are more reasonable at $50-$80/seat, but they come with their own limitations around customization and integration.
Why Teams Replace CRM
The dirty secret of Salesforce: most companies use about 15% of its features. You bought a Swiss Army knife. You needed a scalpel.
The specific pain points that drive replacement:
What a Custom CRM Includes
A replacement CRM built for your workflow typically covers:
That's it. No Einstein AI. No AppExchange marketplace. No features you'll never configure.
Build Cost & Timeline
ROI Example: 100-Seat Sales Team
| Salesforce Enterprise (3 yr) | Custom CRM (3 yr) | |
|---|---|---|
| Year 1 | $198,000 | $40,000 (build + maintenance) |
| Year 2 | $220,000 (11.4% increase) | $8,000 (maintenance) |
| Year 3 | $245,000 (11.4% increase) | $8,000 (maintenance) |
| Admin costs | $285,000 (3 yr) | $0 |
| Total | $948,000 | $56,000 |
| 3-Year Savings | $892,000 |
That's not a rounding error. That's a 94% reduction. Even if the custom build costs twice our estimate, you're still saving over $800K.

2. BI & Analytics Dashboards
Replacement Pressure: 29%
What You're Paying
Tableau for a 50-person analytics team costs $57,000/year at the Creator tier. Looker for the same team runs $75K-$150K/year depending on your negotiation skills.
Why Teams Replace BI Tools
The 29% replacement pressure is driven by a brutal mismatch: most people who access BI dashboards look at 3-5 reports. They don't build visualizations. They don't write DAX queries. They check a dashboard once a day — maybe once a week — and that's it.
You're paying per-seat prices for a product most seats use as a read-only web page.
Additional pain points:
What a Custom BI Dashboard Includes
Build Cost & Timeline
ROI Example: 50 Dashboard Users
| Tableau (3 yr) | Custom Dashboards (3 yr) | |
|---|---|---|
| Year 1 | $57,000 | $30,000 (build + maintenance) |
| Year 2 | $63,500 (11.4% increase) | $6,000 (maintenance) |
| Year 3 | $70,700 (11.4% increase) | $6,000 (maintenance) |
| Total | $191,200 | $42,000 |
| 3-Year Savings | $149,200 (78%) |

3. Workflow Automation
Replacement Pressure: 35% (highest)
What You're Paying
The per-task pricing model is a time bomb. A growing company that runs 50,000 automations per month on Zapier pays $600+/month. Workato at enterprise scale runs $100K/year for what amounts to moving data between systems.
Why This Category Leads Replacement
35% replacement pressure — the highest of any category. The reason is structural: workflow automation tools charge you per operation for logic that, once built, costs almost nothing to run.
A cron job that moves data from your CRM to your billing system runs on a $5/month server. Zapier charges you per execution for the same thing.
Other pain points:
What a Custom Automation Layer Includes
Build Cost & Timeline
ROI Example: Replacing Zapier at Scale
| Zapier + Workato (3 yr) | Custom Workflows (3 yr) | |
|---|---|---|
| Year 1 | $35,000 | $18,000 (build + maintenance) |
| Year 2 | $39,000 (11.4% increase) | $3,500 (maintenance + hosting) |
| Year 3 | $43,400 (11.4% increase) | $3,500 (maintenance + hosting) |
| Total | $117,400 | $25,000 |
| 3-Year Savings | $92,400 (79%) |

4. ITSM & Service Management
Replacement Pressure: ~25%
What You're Paying
ServiceNow is the Salesforce of IT service management. Massive, expensive, deeply entrenched, and used at 20% capacity by most organizations.
Why Teams Replace ITSM
Most IT teams need: a ticket intake system, an assignment workflow, SLA tracking, and a knowledge base. That's four features. ServiceNow offers four hundred.
The AI surcharge is particularly painful here. ServiceNow's "Now Assist" AI features cost 30-45% extra. Most IT teams haven't integrated them into a single workflow. They're paying for AI they don't use, bolted onto a platform they barely use.
What a Custom ITSM Replacement Includes
Build Cost & Timeline
ROI Example: Replacing ServiceNow
| ServiceNow (3 yr) | Custom ITSM (3 yr) | |
|---|---|---|
| Year 1 | $250,000 | $45,000 (build + maintenance) |
| Year 2 | $278,500 (11.4% increase) | $9,000 (maintenance) |
| Year 3 | $310,200 (11.4% increase) | $9,000 (maintenance) |
| Total | $838,700 | $63,000 |
| 3-Year Savings | $775,700 (92%) |

5. Project Management
Replacement Pressure: 23%
What You're Paying
These look cheap individually. A 200-person company on Asana Business pays $60,000/year. Add Jira for engineering ($38,400/year) and Smartsheet for ops ($60,000/year) — because no single PM tool works for everyone — and you're at $158,400/year for project management alone.
The real problem: the average company runs 11 project management tools. Not a typo. Eleven.
Why Teams Replace PM Tools
Generic PM tools force your workflow into their model. Jira is built for sprints. Asana is built for marketing workflows. Monday.com is built for everything (and therefore nothing).
Teams replace PM tools when they realize they're spending more time managing the tool than managing the project.
What a Custom PM Tool Includes
Build Cost & Timeline
ROI Example: Consolidating 3 PM Tools for 200 Users
| 3 PM Tools (3 yr) | Custom PM (3 yr) | |
|---|---|---|
| Year 1 | $158,400 | $32,000 (build + maintenance) |
| Year 2 | $176,400 (11.4% increase) | $6,000 (maintenance) |
| Year 3 | $196,500 (11.4% increase) | $6,000 (maintenance) |
| Total | $531,300 | $44,000 |
| 3-Year Savings | $487,300 (92%) |

6. Customer Support & Helpdesk
Replacement Pressure: 21%
What You're Paying
A 30-agent support team on Zendesk Enterprise pays $41,400/year. Salesforce Service Cloud for the same team: $59,400/year. Scale to 100 agents and those numbers triple.
Why Teams Replace Support Tools
Customer support tools suffer from the same disease as CRM: you pay for an ecosystem when you need a workflow. Most support teams use: ticket management, a knowledge base, live chat, and basic reporting. That's it.
The 21% replacement pressure is lower than other categories because support tools are customer-facing, which makes teams nervous about switching. But the teams that do replace report faster resolution times because their custom tool matches their actual support process instead of forcing it into Zendesk's default workflow.
What a Custom Support Tool Includes
Build Cost & Timeline
ROI Example: 30-Agent Support Team
| Zendesk Enterprise (3 yr) | Custom Support (3 yr) | |
|---|---|---|
| Year 1 | $41,400 | $35,000 (build + maintenance) |
| Year 2 | $46,100 (11.4% increase) | $7,000 (maintenance) |
| Year 3 | $51,400 (11.4% increase) | $7,000 (maintenance) |
| Total | $138,900 | $49,000 |
| 3-Year Savings | $89,900 (65%) |

7. Marketing Automation
Replacement Pressure: ~20%
What You're Paying
HubSpot's Marketing Hub is a classic example of SaaS sprawl within a single vendor. You start with email. Then you add landing pages, social scheduling, ad management, SEO tools, and chatbots. Before you know it, you're paying $43,200/year and using three features.
Why Teams Replace Marketing Automation
Marketing automation has the lowest replacement pressure on this list because the integration complexity is genuinely high. Email deliverability, compliance (CAN-SPAM, GDPR), and multi-channel orchestration are legitimately hard.
But for companies whose marketing automation needs are simpler — email sequences, lead scoring, basic segmentation — the savings from replacing are substantial.
What a Custom Marketing Automation Tool Includes
Build Cost & Timeline
ROI Example: Replacing HubSpot Marketing Enterprise
| HubSpot Enterprise (3 yr) | Custom Marketing (3 yr) | |
|---|---|---|
| Year 1 | $43,200 | $42,000 (build + maintenance) |
| Year 2 | $48,100 (11.4% increase) | $8,000 (maintenance + sending costs) |
| Year 3 | $53,600 (11.4% increase) | $8,000 (maintenance + sending costs) |
| Total | $144,900 | $58,000 |
| 3-Year Savings | $86,900 (60%) |

How to Prioritize: The Replacement Decision Framework
You can't replace everything at once. Here's how to decide what goes first.
Score Each Tool on Three Dimensions
1. Annual cost. Higher cost = higher priority. A $200K ServiceNow contract is more urgent than a $5K form builder.
2. Usage gap. How much of the tool do you actually use? If you use 15% of Salesforce, that's an 85% waste signal. If you use 80% of GitHub, leave it alone.
3. Replacement complexity. Some tools are straightforward to replace (forms, internal dashboards, basic workflows). Others require significant domain expertise (email deliverability, payment processing, compliance engines).
The Priority Matrix
| Priority | Criteria | Categories |
|---|---|---|
| Replace first | High cost + low usage + low complexity | Workflow Automation, Internal Admin, BI Dashboards, Forms |
| Replace second | High cost + low usage + medium complexity | CRM, Project Management, ITSM |
| Replace third | Medium cost + variable usage + high complexity | Customer Support, Marketing Automation |
| Leave alone (for now) | High usage + high complexity + reasonable cost | Source control, CI/CD, cloud infrastructure, payment processing |
Start With One Win
Don't try to replace five tools in parallel. Pick the highest-ROI candidate — usually workflow automation or internal admin tools — and build the replacement. Ship it. Measure the savings. Then use that result to justify the next replacement.
The companies that successfully replace SaaS treat it as a sequence of focused projects, not a big-bang migration.
The Bottom Line
The combined three-year savings across all seven categories for a typical 200-person company:
| Category | 3-Year SaaS Cost | 3-Year Custom Cost | Savings |
|---|---|---|---|
| CRM | $948,000 | $56,000 | $892,000 |
| BI/Analytics | $191,200 | $42,000 | $149,200 |
| Workflow Automation | $117,400 | $25,000 | $92,400 |
| ITSM | $838,700 | $63,000 | $775,700 |
| Project Management | $531,300 | $44,000 | $487,300 |
| Customer Support | $138,900 | $49,000 | $89,900 |
| Marketing Automation | $144,900 | $58,000 | $86,900 |
| Total | $2,910,400 | $337,000 | $2,573,400 |
$2.57 million in savings over three years. That's not theoretical. That's based on published SaaS pricing and real build costs.
