Custom CRM and ERP development for small and mid-sized businesses
We build custom CRMs, ERPs and internal systems for small and mid-sized businesses: customers and pipeline, quotes, inventory, scheduling, client portals and dashboards, integrated with the accounting and payment tools you already use. Sylvara Creative builds them in modules, starting with the one that saves the most time, so you replace spreadsheets without changing how your team works.
What's included
Custom CRM
Your pipeline stages, your fields and your follow-up rules, instead of bending to a generic CRM.
Inventory and orders
Stock per location, orders, purchasing and fulfillment in one system.
Client portal
Customers see their orders, invoices and documents without emailing you.
Dashboards
Sales, margins, receivables and capacity on one screen, updated automatically.
Scheduling and booking
Booking systems built around your real rules: staff, rooms, durations, deposits.
Integrations
QuickBooks, Xero, Stripe, HubSpot, Google Workspace and your existing tools.
Custom CRM or an off-the-shelf CRM?
HubSpot, Salesforce and Pipedrive are excellent when your sales process looks like everyone else's. A custom CRM pays off when your process is specific (complex quotes, field operations, long B2B cycles, regulated data), when you pay for dozens of seats you barely use, or when the CRM has to share data with an internal system it can't talk to.
There is a middle path: keep the CRM you have and build the missing piece around it, such as a quoting tool, a client portal or an integration with your operations system.
Custom ERP software development, one module at a time
A full ERP rollout is risky for a small company. We build the modules you need (inventory, purchasing, production, billing) and connect them to the accounting software your bookkeeper already uses. Each module ships on its own and earns its keep before the next one starts.

Frequently asked questions
How much does a custom CRM cost?
A custom CRM, ERP or internal system starts at USD 12,000, depending on modules and integrations. Because it is built in stages, you can start with one module and add the rest later.
Can it integrate with QuickBooks or Stripe?
Yes. We integrate with QuickBooks, Xero, Stripe, PayPal, HubSpot and most tools with an API, so data is entered once and flows everywhere it is needed.
Who owns the system?
You do. Code and data belong to your company; you get the repository, documentation and full IP assignment in the contract.
Shall we start with a diagnosis?
