Custom CRM Development
Custom CRM for small business owners who outgrew HubSpot and never fit Salesforce.
Off-the-shelf CRM forces your business to bend to the software. A custom CRM does the opposite. Built on the same stack as WallFlow, our production SaaS for wallpaper contractors. Tailored to your workflow, your team size, your industry.

Why off-the-shelf fails
If you've ever paid for a CRM and still ended up running the business out of WhatsApp, you know the gap.
Generic CRM platforms are built for everyone, which means they fit no one specifically. The free tier is too limited. The paid tier is built for a 50-person sales team you don't have. You spend three months configuring it. Six months later you're back in spreadsheets because the workflow your business actually runs doesn't match the workflow the CRM assumes.
Custom CRM solves the opposite problem. Instead of bending your business to fit the software, the software is shaped around how you actually work: the way you take a quote, the way materials get calculated, the way your installer signs off a job, the way payment hits Stripe. Every screen exists because you use it. Nothing exists because it was in a SaaS template.
This only makes sense for businesses with a workflow distinct enough that no off-the-shelf CRM covers it without heavy plugin engineering. Wallpaper contractors. Moving companies with multi-location dispatch. Med spas with appointment chains. Service businesses with calculator-driven estimates. Anything where the right tool would save your team five hours a week and your customers a confused phone call.
What's included
A complete operating system, not a configured template.
01
Workflow discovery
Three calls mapping how your business actually runs today: lead capture, estimate, contract, scheduling, fulfillment, payment, follow-up. We document the real flow, including the duct-tape parts, before writing any code.
02
Custom database schema
PostgreSQL via Supabase. Tables shaped around your domain (jobs, estimates, installers, materials, payments) with row-level security so the right person sees the right data.
03
Owner dashboard
Revenue, outstanding payments, jobs in pipeline, team utilization. The 10-second snapshot you check on your phone over coffee.
04
Mobile-first installer portal
Your field team gets a phone-friendly view of their jobs: location, scope, photos, sign-off. No more texting addresses or losing photos in WhatsApp threads.
05
Client portal (no login required)
Customers see their quote, sign it on their phone, watch project status update live, pay through Stripe. One link, one tap, no password reset email.
06
Lead-flow automation
Form submits trigger CRM tag, notify you, route to the right team member, send the customer a branded auto-reply, queue a follow-up if no response in 48 hours.
07
Stripe and payments
Invoices, deposits, recurring charges, refunds. Full Stripe Checkout and Customer Portal wired up. QuickBooks export when accounting season hits.
08
WhatsApp or Telegram bot
Optional. Lead capture, FAQ answers, booking confirmations through the channel your customers already use.
Proof, not promises
WallFlow is the same architecture, shipped to a real industry.
WallFlow (wallflow.pro) is a production SaaS for wallpaper contractors that I built and operate. Estimates with wallpaper-specific roll calculation and pattern repeat. E-signatures on quotes and contracts. Installer mobile portal. Client portal with project tracking. Multi-tenant Stripe billing. Three languages.
It is the same stack and the same architecture I would use for your business. Next.js for the frontend. Supabase for the database, auth, and storage. Stripe for billing. Vercel for deployment. Multi-tenant from day one, mobile-first throughout, and the kind of UI that doesn't feel like a 2014 SaaS dashboard.
When prospects ask whether I can build a custom CRM for their niche, the honest answer is: I already did, for one. The hard parts (auth, multi-tenancy, billing, role-based access, mobile UX, e-signatures) are solved. The work for your business is mapping your specific workflow into the same proven foundation.

How it works
From discovery call to launched CRM in 30 – 45 days.
Step 01
Discovery (week 1)
Three calls mapping workflow, plus a written scope document. We agree on the data model, the user roles, and the must-have screens before any code is written.
Step 02
Build (weeks 2 – 4)
Database schema, auth, owner dashboard, primary workflow screens. You see deployed previews every Friday. Weekly review call, asynchronous feedback in between.
Step 03
Integrate (weeks 4 – 6)
Stripe billing, e-signatures, automation flows, optional WhatsApp or Telegram bot, QuickBooks or accounting integration. End-to-end testing.
Step 04
Launch and train (week 6 – 7)
Owner training session recorded on Loom. Installer or field team onboarding session. 60 days of post-launch support included to iron out edge cases.
Investment
Transparent pricing. Real ranges.
Custom CRM development falls inside the Site + CRM / Automation tier ($7,500 – $15,000, 30 – 45 days) or the Full Digital Infrastructure tier ($12,000 – $25,000+, 45 – 60 days), depending on whether you need only the CRM or the website plus the CRM. Post-launch retainer for ongoing iteration runs $300 – $1,500 per month. No hidden setup fees, no per-seat licensing, no annual lock-in.
