Custom CRM
Your pipeline, your stages, your follow-up rules. Leads from every source land in one place and go to the right person on their own.
Custom software built around your business.
We replace the pile of apps your team logs into every day with one system built for how you already work. You own it, with no per-seat bill.
What we build
One system instead of five logins.
Every business runs a little differently, so nothing here comes off a shelf. These are the pieces we build most, alone or together.
Client portals
Customers log in to see status, documents, invoices and messages instead of calling for updates. We run our own clients on one.
Intake and booking
Forms, photo uploads, paid consultations and calendar booking that feed straight into the system instead of someone's inbox.
Payments and billing
Deposits, invoices and recurring billing, tied to the job or the client and passed to your accounting.
Integrations
Keep the tools that work, like QuickBooks or Google Workspace, and connect them so nobody retypes anything.
Owner dashboard
Leads, jobs, money and team numbers on one screen, on your phone, with the things waiting on you at the top.
AI built in
Calls and form submissions summarized for you, new leads sorted by what they need, and follow-up messages drafted for your team to send. The AI does the busywork. Your people make the calls. See AI and automation.
Replace
Stop renting software that doesn't fit
If your team copies the same customer into three apps, pays per seat for features nobody opens, or keeps a spreadsheet on the side because the real system can't do it, the software is working against you.
We replace the patchwork with one system, move your data over, and run both side by side until you're ready to switch the old one off.
Salesforce & HubSpot
Paying enterprise prices?
Salesforce, HubSpot and ServiceTitan are built for big companies with admins on staff. A 20-person business on Salesforce Pro Suite pays $2,000 a month before add-ons.
Sometimes the fix is connecting what's missing. Sometimes it's leaving. Here's how we decide, and what moving out looks like.
Who it's for
Businesses big enough to feel the mess.
Our best fit is an established business with a team, real volume, and more apps than anyone can keep straight. We build for:
- Real estate brokerages with lead intake, agents, transactions and commission splits spread across tools
- Builders and contractors juggling estimates, schedules, change orders and customer updates
- Property managers who need owner and tenant portals that match how they actually run
- Freight, trucking and logistics teams dispatching from spreadsheets and phone calls
- Law firms that want a better intake and client-update process (not case files or trust accounting)
- Service companies with crews that have outgrown off-the-shelf field service apps

Process
How a build runs
- Systems AuditWe map every app you pay for, what it costs, and where your team retypes the same information.
- Written plan in partsYou get what to keep, what to connect and what to replace, with a price for each part.
- Build with a checkpointEach part has a halfway checkpoint, so you see real, working software before you commit to the rest.
- Move your dataWe bring your records over, test them against the old system, and run both side by side until you trust it.
- Launch and trainingYour team gets walked through it. Everything runs on accounts in your name.
- Care planFixes, small changes and updates every month, so the software keeps up with the business.
Proof
We run our own business on it
Our clients log in to the SDL Portal to see their rankings and reports. Marcos runs the agency from Synergy HQ, a phone app that shows what needs approval, which sites had problems overnight, and where every client ranks. Both are custom, built in-house.
These are the real apps, not mockups. Numbers and client details are blurred for privacy.
Built for clients too: we built and demoed a working team scheduler for a professional softball team through 108 Performance in Knoxville. Read the team scheduler case study.
FAQ
Questions owners ask us
What does Synergy Digital Apps build?
Custom business software: CRMs, client portals, intake and booking systems, payments and billing, owner dashboards, and integrations between the tools you keep. Each system is built for one business, not resold as a template.
Is custom software cheaper than SaaS?
Not always. A small team happy with a $300-a-month app should keep it. Custom wins when you pay per seat for a big team, stack several apps that don't talk, or pay consultants to bend a tool that doesn't fit. The Systems Audit runs the 5-year math on your real bills.
How much does custom software cost?
Custom CRMs and client portals start at $7,500. Full business platforms start at $25,000 and are built and paid in parts. Care plans start at $399 a month. The $1,500 Systems Audit is credited in full if you go ahead.
How long does a build take?
It depends on how much we replace. The Systems Audit gives you an estimated timeline for each part, and each part has a halfway checkpoint where you see working software. Have a hard deadline? We can expedite to meet it. Rush pricing depends on the size of the build and how fast you need it, and a rush leaves less time for testing.
Do we own the software?
Yes. The code, the data and the hosting accounts are in your name. There is no per-seat fee to us and no lock-in. If you ever want another developer to take over, they get everything.
What happens if something happens to you?
You own the code and it runs on your own accounts, so nothing shuts off. Every system we build is documented, and the care plan covers updates and backups. Another developer can pick it up from the documentation.
Do you build AI into the software?
Yes, where it saves your team time: summarizing calls and form submissions, sorting new leads by what they need, and drafting follow-up messages for a person to review and send. It runs inside your own system, on accounts in your name.
Can you connect the tools we want to keep?
Yes. Most systems keep accounting, email and e-signature tools and connect to them. See integrations.
Where are you located?
Knoxville, Tennessee. We meet East Tennessee clients in person and build for businesses anywhere in the US remotely.

Marcos took the time to help us put together a clear plan for our mobile detailing business, SN Elite. We’ve been trying to figure out our next steps, and having someone walk through things with us made a big difference. He’s great at communicating and explaining things in a way that’s easy to understand. We left the conversation with a better idea of what to focus on and where to go from here. Really appreciate his time and guidance. If you’re a business owner needing direction, I’d recommend reaching out to Marcos at Synergy Digital Lab!

Blaine Stratton.★★★★★
I switched my marketing to Synergy Digital Lab specifically for their 'pay-what-you-rank' model. It’s the most transparent SEO service I’ve found - they send a monthly report showing my average keyword rankings and I pay based on those results. It’s great to finally work with a digital marketing firm that focuses on actual ROI instead of just vanity metrics. If you need a web development and SEO partner that delivers, Synergy is the standard. Speak to the founder. Super transparent and helpful If you need a partner that understands data-driven growth and professional execution, this is the firm. Highly recommended for any business looking to scale their online presence.

Working with Synergy Digital Labs has been an incredible experience. They handled all of my marketing and SEO needs with true professionalism. What impressed me most was how they consistently went the extra mile. We are currently letting Marcos handle 2 more of our companies Website Design, Marketing, and SEO. They took the time to understand my business, offered thoughtful recommendations, and delivered results. -SP

If you're tired of paying for 'efforts' instead of results, talk to Synergy. Their pay-per-rank system is a game changer for my business. I get clear data every month showing exactly where we stand. Best digital marketing decision I've made.

Finally found a marketing agency that prioritizes results over fluff. Synergy's pay-what-you-rank model is exactly what the industry needs. My average rankings are up, and the communication is top-tier.
