How a Consulting Firm Cut Software Costs 60% by Building Custom Tools

Last year, a 12-person consulting firm in Austin was spending $2,100/month on software. Salesforce for CRM ($75/user × 8 users = $600). Monday.com for project tracking ($48/user × 12 = $576). SuiteDash for client portals ($99). Calendly for scheduling ($96). QuickBooks for invoicing ($80). Zapier to glue it all together ($69). Slack for internal comms ($84). Plus another ~$400 in miscellaneous tools.

Their operations manager described it as "software Jenga" — remove one piece and everything wobbles.

By March 2026, they'd replaced four of those tools with custom-built apps. Their monthly software bill dropped to $836. That's a 60% reduction — $15,168 saved per year.

Here's how they did it, what worked, what didn't, and whether this approach makes sense for your business.

The Problem: 9 Tools That Don't Talk to Each Other

The firm — let's call them Apex Consulting — runs strategy engagements for mid-market companies. Think 3-6 month projects with 2-4 consultants per engagement, multiple stakeholders on the client side.

Their workflow looked like this:

1. New lead comes in → Salesforce (CRM)
2. Lead becomes a project → Monday.com (project tracking)
3. Client needs to see progress → SuiteDash (client portal)
4. Book kickoff meetings → Calendly (scheduling)
5. Send invoices → QuickBooks
6. Sync data between tools → Zapier (automation)
7. Internal communication → Slack

The problem wasn't any single tool — each one was fine at its job. The problem was the gaps between them.

When a deal closed in Salesforce, someone had to manually create the project in Monday.com. Client contact info lived in three different systems. Status updates posted in Monday.com didn't appear in SuiteDash, so clients kept emailing "what's the latest?" Invoices in QuickBooks had no connection to project milestones in Monday.com.

The operations manager estimated her team spent 6-8 hours per week on what she called "tool maintenance" — copying data between systems, fixing sync errors, and answering questions that a unified system would answer automatically.

The Decision: Build vs. Buy vs. Keep

They considered three options:

Option A: Keep the stack. $2,100/month, 6-8 hours/week of manual sync. Frustrating but functional.

Option B: Consolidate into one platform. HubSpot's CRM Suite ($1,600/month for their team size) or Zoho One ($444/month). Both would mean months of migration and retraining, with compromises — no tool does everything well.

Option C: Build custom tools for the workflows that matter most. Keep the tools that work (Slack, QuickBooks) and replace the ones that don't with purpose-built apps.

They chose Option C — but not in the way you'd expect. They didn't hire a development agency. They built the apps themselves.

What They Built (and What They Kept)

Replaced: Salesforce → Custom CRM ($9/month)

Salesforce is incredible software if you're a 200-person sales org with a full-time admin. For an 8-person team that tracks maybe 30 active deals, it's a Ferrari parked in a school zone.

They described what they needed: "A CRM with contacts, companies, and a deal pipeline. Kanban view for deals with stages: Lead, Qualified, Proposal, Negotiation, Closed Won, Closed Lost. Activity log for each contact. Dashboard with pipeline value and win rate."

3 minutes later, they had a working CRM that did exactly that — nothing more, nothing less. The crucial difference: it was theirs. When they later needed a "referred by" field and an automatic follow-up reminder, they added it in another 15-minute session.

Savings: $600/month → $9/month = $591/month saved

Replaced: Monday.com + SuiteDash → Custom Project Tracker with Client Portal ($9/month)

This was the big one. Two tools replaced with one because the whole point of the client portal was to show project status — which is project tracking data.

The description: "A project management tool for consulting engagements. Each project has a client, assigned consultants, milestones with due dates, and a status. Clients can log in to see their project's progress, milestones, and shared documents. Consultants post updates and upload deliverables. Admin dashboard shows all active projects, overdue milestones, and utilization rates."

The resulting app gave consultants a clean internal view and clients a simpler external view — same data, different perspectives. No more copying updates from one tool to another.

Savings: $675/month → $9/month = $666/month saved

Replaced: Calendly → Custom Scheduling Tool ($9/month)

Calendly works well, but it doesn't know about your projects. When a client books a "project review" meeting, Calendly doesn't connect that to the actual project.

Their custom scheduling tool pulled available times from Google Calendar (same as Calendly) but linked each booking to a project and automatically notified the assigned consultants. Meeting notes were stored on the project timeline, not in a separate app.

Savings: $96/month → $9/month = $87/month saved

Kept: Slack, QuickBooks, Zapier (reduced)

Slack stayed — it's genuinely the best at what it does, and they'd already built their culture around it.

QuickBooks stayed too. Accounting software is heavily regulated, integrates with tax filing, and needs to handle edge cases that a custom app shouldn't attempt.

Zapier stayed but dropped from the $69 plan to the free tier. They'd been using it mainly to sync Salesforce→Monday.com and Monday.com→SuiteDash. With those tools gone, they only needed a few simple automations.

The Numbers

But the money wasn't the biggest win. The operations manager reported that "tool maintenance" dropped from 6-8 hours/week to about 1 hour. That's 300+ hours/year of consultant time freed up — at their billing rate of $200/hour, that's $60,000 in recovered capacity.

What Didn't Work

Honesty time: not everything went smoothly.

First attempt at the CRM was too complex. They described everything they wished Salesforce could do, which produced an app with 15 fields per contact and a confusing dashboard. Second attempt: they stripped it down to what they actually use daily. Much better.

Data migration took longer than building. Exporting contacts from Salesforce and deals from Monday.com, then importing them into the new tools, took a full afternoon. The apps were built in 3 minutes each, but migration took 4 hours total.

Team adoption required a push. Three consultants kept going back to Salesforce out of habit for the first two weeks. The ops manager had to set a hard cutoff date: "After March 1, if it's not in the new CRM, it doesn't exist." That worked.

The scheduling tool needed iteration. First version didn't handle timezone differences for remote clients. Second version fixed it, but that was another 15-minute session plus testing.

When This Approach Makes Sense

This worked for Apex because:

• Small team (under 50 people) — everyone can learn a new tool quickly
• Standard but specific workflows — not so unique that you need custom logic everywhere, but specific enough that generic tools don't fit perfectly
• Pain concentrated in 2-3 tools — they didn't replace everything, just the painful parts
• Someone owns it — the operations manager took responsibility for the tools

This probably wouldn't work for:

• Large enterprises — too many stakeholders, too many integrations, too much process
• Heavily regulated industries — healthcare, finance, and legal have compliance requirements that need certified platforms
• Teams without a technical champion — someone needs to own the tools, test changes, and handle edge cases

The Broader Pattern

Apex isn't unique. A pattern is emerging among small professional services firms: the SaaS stack that grew organically over 5 years is now bloated, expensive, and fragile. Each tool was the right choice when it was added. Together, they're a mess.

The traditional fix — "let's consolidate into one platform" — usually means spending 6 months evaluating vendors, another 6 months migrating, and then discovering that the one-size-fits-all platform doesn't fit your specific workflow either.

The alternative: keep what works, replace what doesn't with purpose-built tools, and own the code so you can iterate without filing support tickets.

It's not for everyone. But for a 10-50 person company spending $1,500-5,000/month on SaaS tools that don't quite fit? The math gets very compelling very fast.
