Two ways to work with us

Built from scratch.
Or customised on Odoo.

Both deliver the same outcome - a system that fits your business. The right choice depends on your requirements, timeline, and long-term plans.

Path 01

Fully Custom CRM & ERP — Built from Scratch

We design and develop your entire system ground-up using React, Node.js, and PostgreSQL. Every model, every field, every permission, every workflow built specifically for your business. No platform constraints. No licensing fees. No seat limits. Total ownership.

React + Node.js PostgreSQL AWS Hosted Full Source Code No Seat Limits
Path 02

Odoo Customisation — Open-Source ERP Platform

Odoo is one of the most powerful open-source ERP platforms available. We customise it deeply — custom Python modules, tailored workflows, third-party integrations, and Odoo-native reporting — so it operates exactly the way your business does. Faster to deploy. Proven platform.

Custom Python Modules Odoo Third-Party Integration Odoo.sh or Self-Hosted

Not sure which path fits? We recommend the right option during your free discovery call — based on your requirements, not on what earns us more.

Why businesses choose custom

Most CRM failures are
fit failures.

"The software didn't match how the team actually worked — so the team quietly stopped using it."

Ready-made CRM and ERP software is built for thousands of businesses simultaneously. That breadth is exactly the problem.

Your claims process doesn't look like a generic sales pipeline. Your field agents don't operate like an e-commerce support desk. Your workflow has specific stages, specific handoffs, and rules that no off-the-shelf tool was designed to hold.

When software doesn't fit, two things happen. Either your team bends their process to fit the tool — introducing friction and shadow spreadsheets. Or they quietly stop using the system altogether.

A custom CRM or a properly customised Odoo instance doesn't compromise. It starts with your workflow and builds outward.

What we build

Eight modules.
Every one purpose-built.

01
Pipeline & Lead Management

Custom stages matching your actual process. Assignment rules, ownership tracking, and stage-change triggers. Your pipeline reflects your reality.

02
Role-Based Access Control

Agents, managers, supervisors, admins — each sees exactly what their role requires. Field-level permissions. Sensitive data stays controlled.

03
Activity & Communication Log

Calls, emails, WhatsApp messages, meetings — all logged against the record automatically. Full history visible to the right people.

04
Workflow Automation

When a claim reaches a stage, notify the adjuster. When a lead goes idle, alert the manager. Automation built around your rules.

05
Custom Reporting & Dashboards

Reports on your actual KPIs — not an approximation. Pipeline velocity, team performance, revenue per segment. CSV and PDF export on demand.

06
API & Third-Party Integration

Payment gateways, logistics APIs, WhatsApp Business, accounting tools, e-commerce platforms. Your systems work as one unified operation.

07
Document Management & Audit Trail

Upload, store, and version documents within records. Full audit log of every action — who changed what, when, and from which state.

08
ERP — Inventory, HR & Finance

Inventory tracking, purchase orders, employee records, payroll summaries, and financial reporting alongside the CRM core. One source of truth.

Proof of work

A system that eliminated
80% of manual paperwork.

The challenge

An insurance business was managing its entire claims lifecycle through spreadsheets, email threads, and manual handoffs. No centralised tracking. No audit trail. No way to measure resolution time or identify where claims were getting stuck.

Status updates were inconsistent. Documents were duplicated. Resolution timelines were impossible to improve because no one could see the full picture.

What we built

A ground-up Insurance Claim CRM covering the complete lifecycle. Agents had structured intake screens that auto-populated records. Adjusters received role-filtered views. Supervisors got a real-time dashboard of every open claim, its stage, owner, and time-in-stage.

Every action logged. Every document versioned. Every change timestamped. Nothing fell between roles.

Technology

A stack chosen for
your long-term benefit.

Every architectural decision is made for your system's long-term maintainability — not for our convenience.

Frontend
React

Component-level control over every screen. Fast, responsive, and maintainable by any developer after handover.

Backend API
Node.js

Processes business logic, handles auth, enforces permissions, and connects your database to your frontend.

Database
PostgreSQL

Relational structure. ACID compliance, row-level security, and the query performance your dashboards require.

Infrastructure
AWS

Scales when you need it. Environment separation, backups, monitoring and alerting on every deployment.

Design
Figma

Every screen approved before code is written. No surprises at demo time. You see the interface before it is built.

Odoo path:Python · XML · OWL (Odoo Web Library) · PostgreSQL · Odoo.sh or self-hosted. All custom modules follow Odoo community standards — upgradeable, documented, and transferable to any Odoo developer.

How we work

From first call
to live system.

Most projects fail in the first two weeks — not bad code, but undefined requirements and a scope nobody formally agreed on.

01
Week 1
Workflow mapping & discovery

We do not write a single line of code in week one. We learn how your business operates — every role, every stage, every handoff, every rule. Output: a written workflow map you sign off before we design anything.

02
Week 2
Architecture, schema & fixed-price proposal

Every model, field, permission boundary, and integration point defined in writing. We then price the project at a fixed cost. The number we quote is the number you pay. No hourly rates. No surprises at invoice.

03
Week 3
UI/UX design — every screen approved

Every screen wireframed at full fidelity in Figma. You review and approve before development begins. Changes here cost nothing. Changes after coding cost time and budget.

04
Weeks 4–12
Sprint development with weekly demos

One-week sprints. Every Friday a working demo you can click through — not a status report. Milestone-based payments: you pay for work that is demonstrably done, not work promised to be done.

05
Week 13
UAT with your actual team

Your real team tests the system against your real workflows — role by role. Every issue resolved before a go-live date is confirmed. UAT is not a formality here.

06
Week 14–15
Deployment, training & full handover

Production deployment, role-specific training, technical documentation, and full source code transfer to your repository. You own everything from this point.

Honest assessment

When custom is right.
When it isn't.

Build custom — or customise Odoo — when:
  • Your process has stages or rules that don't map to any standard pipeline
  • You need deep integration with tools you already own — billing, logistics, WhatsApp Business, field ops
  • Your team has rejected ready-made software before — not laziness, but because it didn't reflect how they work
  • Sensitive business logic shouldn't live in a third-party platform you don't control
  • You need reports on your actual KPIs — not an approximation
  • Licensing cost at your team size makes a custom build the smarter 3-year investment
Stick with ready-made software when:
  • You are early stage and need something running today — custom takes weeks to scope
  • Your process is genuinely standard and off-the-shelf fits it well
  • You have no technical resource to maintain a custom system post-launch
  • Team is small enough that licensing costs are negligible
We have this conversation with every client before proposing anything. If ready-made software serves you better, we will tell you — and point you in the right direction.

The honest numbers

Custom build vs.
ready-made software.

The right answer depends on team size, process complexity, and how long you plan to operate the system.

Custom Build — 7Sisters Tech Ready-Made CRM Software
Cost model✓ One-time build investmentPer-user monthly fee, ongoing
After 3 years (10 users)✓ Build cost + ~$6K hosting total$36K–$60K licensing alone
Price increases✓ None — you own the systemVendor-controlled, annually
Workflow fit✓ 100% built to your processApproximates your process
Code & data ownership✓ Full ownership on deliveryNone — you rent access
Seat limits✓ No seat count, everEvery user adds to the bill
Customisation depth✓ Unlimited — your rules, your modelsLimited to platform boundaries
Typical break-even vs. ready-made licensing: 18–24 months for a 10-user business with a non-standard workflow. We model this with you during the free discovery call.

Common questions

Everything you need to know
before deciding.

Both. We build fully custom ERP systems from scratch using React, Node.js, and PostgreSQL when your requirements go beyond what any platform provides. We also customise Odoo deeply — custom Python modules, workflow automation, and third-party integrations — for businesses that want a proven open-source foundation. During the discovery call we recommend the right path based on your requirements.
Ready-made software is built for the average business across thousands of industries — within their boundaries. A custom CRM means building the data model, permission system, and interface around your workflow from scratch. If your process requires a stage, field, or rule that doesn't exist in any standard tool, we build it. That is not possible with configuration alone.
A focused CRM with core pipeline, role-based access, activity tracking, reporting, and one or two integrations typically takes 12 to 16 weeks. An ERP with inventory, HR, and finance modules is typically 20 to 28 weeks. An Odoo customisation with one or two modules is typically 4 to 8 weeks. All timelines are agreed in writing before development begins.
Yes. We map your existing data to the new schema, clean it during migration, run against a test database, validate, and execute the final migration with a parallel period running before the old system is retired. Whether data is in spreadsheets, another CRM, or a legacy system — we handle the full transfer.
You own everything — full source code, all repositories, the database schema, Figma design files, and infrastructure configuration, all transferred on project completion. The codebase follows industry-standard conventions so any competent development team can continue the system. No lock-in of any kind.
Every project includes a 60-day post-launch support period at no additional cost. Any defect from our development is fixed within 24 hours. Critical production outages receive a 4-hour response regardless of timezone. Monthly maintenance packages are available after the 60-day window at a fixed monthly cost.
Every system we build is fully responsive on desktop, tablet, and mobile browser. If your team needs native mobile features — offline access, GPS, camera, or push notifications — a companion mobile app can be scoped alongside the web platform.
Yes. Post-launch additions are scoped as change requests with a fixed cost and timeline agreed in writing before work begins. Clients on monthly maintenance packages receive priority scheduling and discounted rates on feature additions.
