Custom CRM & ERP Systems

When Salesforce, HubSpot, or NetSuite make you bend your process to fit the tool, we build CRM and ERP systems around your actual workflow — with the systems integration and role-based access a real system of record needs.

Why Avenva

What sets working with us apart

You own the code

No proprietary lock-in — the repository, infrastructure, and IP are yours from day one.

No vendor lock-in

Standard, well-documented stacks, so your next team (or ours) can extend it without a rewrite.

One team, start to finish

The same engineers scope, build, and support your project — no hand-offs between sales and delivery.

Direct access to engineers

You talk to the people writing the code, not an account manager relaying messages.

Fixed-scope, transparent pricing

Clear estimates before work starts, and no surprise change orders for work that was always in scope.

Support after launch

Launch day isn't the finish line — we stay on for monitoring, fixes, and iteration.

What's included

What we deliver

Custom CRM builds

Pipelines, qualification rules, and reporting that match how your reps actually sell, instead of a generic funnel bent to fit whichever tool you bought.

ERP implementation & migration

Inventory, scheduling, and operations logic built for your actual business model, migrated off legacy systems without a risky single-cutover weekend.

Systems integration

Deep integration with your identity provider, accounting software, and the tools you already run — a new system of record has to work with what's there.

Role-based access & audit trails

Finance, sales, and ops each see exactly what they need, with an audit trail that holds up when someone asks who changed what and when.

Is this you?

Where this actually pays off

Per-seat pricing is starting to work against you at scale

Once your headcount grows, per-seat SaaS pricing on a CRM or ERP can flip from a convenience to your largest recurring line item — the math is worth running honestly.

Your team re-keys the same data into multiple systems

If a claim, order, or lead touches five disconnected tools and someone manually re-enters it into each one, that's pure process friction a unified system removes directly.

Your sales or ops process doesn't match the tool's template

Workarounds, side spreadsheets, and rituals everyone just knows are a sign the off-the-shelf tool is costing you more than its license fee.

You're migrating off a system nobody trusts anymore

Years of workarounds and permission exceptions in a legacy CRM or ERP usually mean a rebuild people don't route around beats another patch.

Our approach

How we run this engagement

01

Process audit

Map how your team actually sells or operates, exceptions included.

02

Architecture

Design the data model, roles, and integrations around that real process.

03

Phased migration

Run in parallel with the legacy system until the new one has earned trust.

04

Handoff & support

Documentation, training, and an ongoing support plan.

Tech we use

Built on a proven, modern stack

Node.js

The API layer connecting your CRM/ERP data to every tool that needs it.

PostgreSQL

Audit-grade data integrity for records that matter when someone asks who changed what.

TypeScript

Types that document your business rules and catch mismatches before production.

.NET

A strong fit when your existing enterprise stack is already Microsoft-centric.

REST/GraphQL APIs

Integrates your accounting, identity, and ops tools instead of replacing all of them.

Docker

Consistent environments from development through the production system of record.

Proof

Work we've shipped like this

“Communication was excellent throughout — no black-box weeks, no surprises at launch. Just steady, visible progress.”

Questions

Things people ask before starting

Can't find what you're looking for? Reach out and we'll answer directly.

Configuration has a ceiling — when your workflow genuinely doesn't fit the tool's model, or per-seat pricing starts working against you at scale, a custom system usually costs less over a few years than continuing to force-fit one. We'll say so honestly if your case doesn't clear that bar yet.
