Software built around
your workflows.
Not someone else's.
Custom CRM and ERP systems — built from scratch or customised on Odoo — designed around how your business actually operates. Role-based access, automation, reporting, and full integration.
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, however, depends on your requirements, timeline, and long-term plans.
Fully Custom CRM & ERP — Built from Scratch
We design and develop your entire system ground-up using React, Node.js, and PostgreSQL. As a result, every model, every field, every permission, and every workflow is built specifically for your business. There are no platform constraints, no licensing fees, and no seat limits — in short, total ownership.
Odoo customization — 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 that it operates exactly the way your business does. In practice, this means faster launch on a proven platform. In other words, Odoo's full power shaped entirely around your business, without the constraints of a generic setup.
Not sure which path fits? We recommend the right option during your free discovery call, based on your requirements rather than 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 precisely the problem.
Your claims process doesn't look like a generic sales pipeline. Moreover, field agents don't operate like an e-commerce support desk. In practice, every workflow has specific stages, specific transfers, and rules that no off-the-shelf tool was ever designed to hold.
Two outcomes - neither of them good
When software doesn't fit, two things tend to happen. Either the team bends their process to fit the tool introducing friction and shadow spreadsheets. Alternatively, they quietly stop using the system altogether.
A custom CRM or a properly customised Odoo instance - doesn't compromise. Instead, it starts with your actual workflow and builds outward from there. Consequently, adoption is higher, data is cleaner, and the system actually gets used.
What we build
Eight modules.
Every one purpose-built.
Custom stages matching your actual process. Assignment rules, ownership tracking, and stage-change triggers. Your pipeline reflects your reality, not a generic template.
Agents, managers, supervisors, admins — each sees exactly what their role requires. Field-level permissions ensure sensitive data stays controlled at all times.
Calls, emails, WhatsApp messages, meetings — all logged against the record automatically. As a result, the full history is always visible to the right people.
When a claim reaches a stage, notify the adjuster. When a lead goes idle, alert the manager. Consequently, nothing falls through the cracks due to manual oversight.
Reports on your actual KPIs — not an estimate. Pipeline velocity, team performance, revenue per segment. Furthermore, CSV and PDF export is available on demand.
Payment gateways, logistics APIs, WhatsApp Business, accounting tools, e-commerce platforms. As a result, your systems work as one unified operation.
Upload, store, and version documents within records. Additionally, a full audit log of every action — who changed what, when, and from which state — is maintained automatically.
Inventory tracking, purchase orders, employee records, payroll summaries, and Additionally financial reporting alongside the CRM core. One source of truth, rather than separate systems.
Proof of work
A system that eliminated
80% of manual paperwork.
Insurance Claim Process CRM
Full end-to-end claim lifecycle platform — system design, database, REST APIs, React frontend, and role-based access for agents, adjusters, and supervisors. Built from scratch. Deployed on AWS.
The challenge
An insurance business was managing its entire claims process through spreadsheets, email threads, and manual handoffs. As a result, there was no organized tracking, no audit trail, and no way to measure resolution time or identify where claims were getting stuck.
Status updates were inconsistent and documents were duplicated. Moreover, 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 process. Agents had structured intake screens that auto-populated records, while adjusters received role-filtered views tailored to their responsibilities. Furthermore, supervisors got a real-time dashboard of every open claim, its stage, owner, and time-in-stage.
Every action was logged, every document versioned, and every change timestamped automatically. Consequently, 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. As a result, any developer can continue the work after handover.
Component-level control over every screen. Fast, responsive, and maintainable by any developer after handover.
Processes business logic, handles auth, enforces permissions, and connects your database to your frontend.
Relational structure. ACID legal requirements, row-level security, and the query performance your dashboards require.
Scales when you need it. Environment separation, backups, monitoring and alerting on every launch.
Screens are approved before a single line of code is written. No surprises at demo time — you see the interface before it is built.
How we work
From first call
to live system.
Most projects fail in the first two weeks — not because of bad code, but due to undefined requirements and a scope nobody formally agreed on.
Discovery & Planning
We do not write a single line of code in week one. Instead, we learn how your business operates — every role, every stage, every handoff, every rule. The output is a written workflow map you sign off before we design anything.
At this stage, every model, field, access rules, and integration point is defined in writing. We then price the project at a fixed cost — the number we quote is the number you pay. There are no hourly rates and, therefore, no surprises at invoice.
Design & Development
All screens are wireframed at full fidelity in Figma for your review and approval before development begins. Changes at this stage cost nothing. By contrast, changes after coding cost time and budget — which is exactly why we front-load this step.
Development runs in one-week sprints. Every Friday you receive a working demo you can click through — not a status report. Consequently, there are no surprises at delivery. Furthermore, milestone-based payments mean you pay for work that is clearly done, not work merely promised.
Launch & handover
Your real team tests the system against your real workflows — role by role. All issues are resolved before a go-live date is confirmed. UAT is not a formality here; rather, it is the final quality gate.
This final phase covers production launch, role-specific training, technical documentation, and full source code transfer to your repository. From this point forward, you own everything.
Honest assessment
When custom is right.
When it isn't.
- 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 estimate
- Licensing cost at your team size makes a custom build the smarter 3-year investment
- 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
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. However, the numbers below give a clear starting point.
| Custom Build — 7Sisters Tech | Ready-Made CRM Software | |
|---|---|---|
| Cost model | ✓ One-time build investment | Per-user monthly fee, ongoing |
| After 3 years (10 users) | ✓ Build cost + ~$6K hosting total | $36K–$60K licensing alone |
| Price increases | ✓ None — you own the system | Vendor-controlled, annually |
| Workflow fit | ✓ 100% built to your process | Approximates your process |
| Code & data ownership | ✓ Full ownership on delivery | None — you rent access |
| Seat limits | ✓ No seat count, ever | Every user adds to the bill |
| Customization depth | ✓ Unlimited — your rules, your models | Limited 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. | ||
