Custom CRM development is building a CRM around the way your team actually sells, instead of bending your process to fit a packaged tool. Kivo Marketing designs and codes custom CRMs, B2B portals and multi-tenant SaaS from Miami and Barcelona. We built Kivo CRM, our own multi-tenant CRM, so yours ships as production software, not a prototype.

What is custom CRM development, and when is it worth it?
A packaged CRM gives you a pipeline, contacts and reports that work the same way for everyone. Custom CRM development starts from the other end: your sales model, your approvals, your pricing rules and the tools your team already opens every morning. The software is written to fit those.
It costs more up front than a monthly license, and someone has to maintain it. So it only makes sense when the packaged route is already costing you. These are the usual signs:
- Your team keeps a spreadsheet next to the CRM because the CRM can't hold how you really work.
- Different customers see different prices, catalogs or steps, and the tool can't tell them apart.
- Onboarding, approvals or orders arrive by email and someone copies them in by hand.
- You pay for seats and add-ons you don't use, and still miss the one feature you need.
- You want to sell the software itself to other companies, as a SaaS.
Custom CRM vs off-the-shelf: how to decide
Neither is better by default. It depends on how far your process sits from the standard one. If a normal pipeline covers it, configure a packaged CRM and spend the money elsewhere. If that's your case, we'll say so.
There is also a middle road, and it's often the right one: keep the CRM you have and build the piece it can't do. A partner or customer portal is the typical example of that piece.
| Off-the-shelf CRM | Custom CRM | |
|---|---|---|
| Fit with your process | You adapt to the tool | The tool follows your process |
| Upfront cost | Low: setup and configuration | Higher: design and build |
| Monthly cost | Licenses per user | Hosting and maintenance |
| Integrations | The ones the vendor offers | The ones your business runs on |
| Data and access | On the vendor's terms | Whatever your contract says |
| Time to start | Right away | After the build, released in phases |
| Who maintains it | The vendor | The team that built it, or yours |
Custom CRM development services: what we build
Portals, internal tools and SaaS, with secure access and Stripe billing built in. One team draws the screens and writes the code, so what you approve in design is what ships.
- CRMs and internal tools. Pipelines, contact records, tasks and the admin screens your team works in all day.
- B2B and partner portals. Onboarding, approvals, catalogs and pricing by account type for distributors and resellers.
- Multi-tenant SaaS. One product, many companies, each with its own data and its own users.
- Dashboards, reporting and forecasting. The numbers your team asks for every Monday, on one screen.
- Payments and billing. Stripe built into the product, not bolted on.
- Integrations. Zoho CRM and Zoho Inventory, Gmail, Stripe, WhatsApp Cloud API and n8n workflows. When the system needs agents that act on their own, that's our AI automation work, plugged into the same build.
Kivo CRM: why we built our own CRM as a product
Our clearest proof is our own. Kivo CRM is a multi-tenant CRM with a kanban pipeline, visual automations, an AI copilot that answers from the real records, a Gmail inbox inside the CRM and billing with Stripe.
A product built for many companies forces the hard parts early: keeping each company's data apart, permissions, billing, and automations that can't break someone else's account. A custom CRM for one company runs into the same problems once it grows.
It runs on Next.js, NestJS, PostgreSQL with Drizzle, Stripe and the Claude API. See it on our work page.
B2B portal development: the Nuderma Partner Portal
Nuderma Group is a dermocosmetics house with four brands, and its partner portal is where distributors apply, get approved and see the catalog and pricing for their account type. We built that portal as custom software with Next.js, n8n, Zoho CRM and Stripe. The full story is in the Nuderma Group case.
What the portal does:
- Onboarding in five steps.
- Passwordless access with a one-time code, so there is no password to forget or leak.
- Catalog and pricing that change with the account type.
- An admin desk that approves every application.
A custom software development company in Miami and Barcelona
Kivo Marketing has teams in Miami, FL and Barcelona, and has been independent since 2015. We work in English and Spanish for companies in the US, Spain and LATAM. The same team designs and codes, with no mockups handed to a third party, whether you need a full SaaS or one internal tool. If the portal also needs the site that sends customers to it, that's our web design and development service.
Every project runs in four steps:
- Get the brief right. How you sell today, where the data lives and who approves what.
- Design the whole thing. Screens, roles and data model, drawn together.
- Build it for real. TypeScript, Next.js, NestJS and PostgreSQL, with Stripe and the integrations you need.
- Launch and sharpen. We measure, tune and keep improving after go-live.

Frequently asked questions
How much does a custom CRM cost?
It depends on three things: how many roles and screens it needs, how many tools it connects to, and whether it serves one company or many, as a SaaS does. After launch you pay for hosting and maintenance instead of per-user licenses. Kivo Marketing doesn't publish fixed prices yet, so we quote after the brief. A first phase can stay small: the pipeline and the screens your team uses most. We break the cost down, line by line, in how much does a custom CRM cost.
Is a custom CRM worth it for a small business?
Often not at first. If a standard pipeline covers how you sell, a packaged CRM is cheaper and faster to start. Building starts to pay when the work your team does around the CRM by hand costs more than the license. A small business can also begin with one custom piece, like a portal, and keep its current CRM.
Can you build a custom CRM with AI?
Yes. Kivo CRM has an AI copilot that answers from the real records, and AI assistants and copilots are part of what we build for clients, with the Claude API or OpenAI as the model. A copilot earns its place on the questions your team asks every week, like which deals have stalled, as long as every answer traces back to a record.
Who owns the code and the data in a custom CRM?
Settle it in writing before the build starts. The contract should say who owns the code, where the software and the database are hosted, who holds admin access and what happens if you change providers. Those four answers matter more than the stack.
Who maintains a custom CRM after launch?
Someone has to, and that's the real trade-off of building custom. At Kivo, the team that designed and built the system keeps measuring, tuning and improving it after go-live. Agree up front what that work covers: updates, fixes and new features.
