Custom CRM development

Lead management software that fits your sales process - not the other way round.

We build custom CRM and lead management systems that capture every enquiry, route it to the right person, remind your team to follow up and show management exactly which campaigns bring in customers.

Lead management & CRM

Every lead captured, followed up and measured

Enquiries arrive from your website, ad campaigns, email, WhatsApp, marketplaces and phone calls. Without one system, leads go cold in inboxes, follow-ups get forgotten and nobody can say which campaigns actually produce customers. A CRM built around your real stages fixes that - and your team stops working around the software.

What we build

  • Automatic lead capture from web forms, landing pages, ads and email
  • Duplicate detection by phone and email
  • Rule-based or round-robin lead assignment with SLA timers
  • Follow-up reminders and escalations
  • Full activity timeline: calls, messages, quotes and status changes
  • Role-based access for teams, branches and management
  • Live MIS dashboards and exportable reports
  • Integrations with your website, email, WhatsApp, accounting or ERP

Why OASIS

We built the MIS lead management system for Six Sigma Synergy in Malaysia, alongside CRM, portal and data platforms for clients in the UK and the EU. You get a system designed around your stages, fields and reports, with no per-user fees, full ownership of the code and data, and ongoing support after launch.

Scope a lead system

Who it is for

Built for teams that have outgrown spreadsheets and generic CRMs

Multiple lead sources, several salespeople and management that needs honest conversion numbers.

Education & training

Enquiry to counselling to enrolment, with documents, payments and batch allocation in one place.

Recruitment & relocation

Candidates, employers and documents moving through many stages across countries.

B2B distributors

Dealer enquiries, quotes, follow-ups and repeat orders tracked per account.

Service companies

Site visits, proposals, approvals and renewals with automatic reminders.

Teams with other systems

A CRM that talks to your website, ERP, accounting or marketing tools instead of living on its own.

How we build

From your sales process to a working CRM

We start with how your team actually sells, then build the system around it - with you seeing progress at every stage.

  • PHP (custom MVC)
  • MySQL
  • REST APIs
  • JavaScript
  • Bootstrap 5
  • Payment gateways
  • WhatsApp Business API
  1. 01

    Discovery & data model

    We map your workflows, users and data sources, then agree scope, milestones and a fixed quote.

  2. 02

    Clickable prototype

    You see the screens and user journeys before development starts - and shape them while changes are cheap.

  3. 03

    Build in sprints

    Working modules on a staging server every sprint, with data migration and integrations tested along the way.

  4. 04

    Go-live, training & AMC

    Deployment, user training and an annual maintenance contract that keeps the system secure, backed up and evolving.

Multi-branch and multi-country

Built for sales that runs from more than one office

A single-office team can get by on a shared inbox for longer than anyone admits. The moment the same business sells from several branches, or across countries, the cracks show immediately: an enquiry arrives, nobody is sure whose it is, and by the time somebody calls, the buyer has already spoken to two competitors.

We build lead management systems for distributed teams in Malaysia, the United States, the Middle East and Europe, and the same requirements come up every time:

  • Assignment by rule, not by whoever is online. Territory, country, product line, language, or round robin within a branch - set by a manager, changed without a developer.
  • Escalation on silence. If an assigned lead is not touched inside the agreed window, it reassigns and somebody is told. This one rule changes response times more than any amount of training.
  • Response clocks that respect working hours. A lead arriving at 11pm in one country is mid-morning in another. Clocks run against the receiving branch's hours, or the reports punish the wrong people and nobody trusts them.
  • Visibility rules that match your org chart. Salesperson sees their own, branch manager sees the branch, head office sees everything - and regional managers see the countries they actually run.
  • Duplicate and ownership handling. The same company enquiring through two branches is normal. The system flags it at creation, shows both histories and applies one written ownership rule, so it never becomes a meeting.
  • Local reality built in. Multiple currencies, languages, tax identifiers, WhatsApp as a first-class lead source, and data residency where the client requires it.

The thinking behind these rules is set out in our guide to lead management for a multi-branch sales team.

Custom lead management system vs an off-the-shelf CRM

We will say it plainly: if your process is close to the standard funnel and your team is small, buy a subscription CRM. It is the cheaper, faster answer and we will tell you so. Building becomes the better choice when the rows below start describing your business.

 Off-the-shelf CRMCustom lead management system
Assignment logicStandard rules; complex branch or territory logic often needs paid add-ons or workaroundsExactly your rule, including the exceptions, editable by a manager
Cost as you growPer user, per month, every month - rises with every hire and every branchOne-off build plus hosting and maintenance; adding users costs nothing
ReportsStandard dashboards; the report management actually wants is often rebuilt by handYour MIS, calculated once, available to everyone the same way
Process fitYou adapt your process to the productThe system models the process you already run
IntegrationsHundreds available; the one you need may not be among themBuilt for the systems you actually use, including local and legacy ones
Data and ownershipHosted where the vendor chooses; export is rarely as clean as promisedYou own the code, the database and the data, hosted where you need it
Time to first useDaysFour to six weeks for the first branch
Who maintains itThe vendorUs, under an AMC - or your own team, since you have the code

The full build-or-buy test, with the five signs you have outgrown a subscription, is in custom lead management software vs an off-the-shelf CRM.

The MIS layer: reports your management actually runs on

Most lead systems stop at the pipeline. The reason clients keep ours is the reporting layer underneath it - what is usually called an MIS lead management system, and the phrase most of our clients in Malaysia and the Gulf use.

That means the numbers management asks for are calculated in one place, from one definition, and are available on a Monday morning without anybody assembling a spreadsheet:

  • Leads by source, branch, product line and salesperson, with conversion at each stage.
  • Average time to first contact, by branch, against working hours.
  • Leads with no contact recorded at all - the number most businesses have never seen, and the one that usually pays for the project.
  • Pipeline value by stage and expected close date, in each branch's currency and a group total.
  • Salesperson activity: calls logged, quotes sent, follow-ups overdue.
  • Scheduled email reports to the people who will not log in, because the report nobody opens is not a report.

Where a client needs the same discipline applied to their core records as well as their leads, we build it alongside an MIS and data management system.

One business, since 2010

The clearest proof of how we build these is a system still running after three rebuilds: an MIS lead management system for a corporate training provider in Malaysia, live since 2010, with 18,000+ enquiries tracked and 300 to 500 added every month.

Built for your industry

The rules change by sector, so the system should too. We have a dedicated page for admission CRM and lead management for schools, colleges and training institutes, with healthcare and real estate to follow. If your sector is not listed, the same approach applies - tell us how your enquiries arrive and who has to act on them.

Questions

CRM & lead management FAQ

Why build a custom CRM instead of using an off-the-shelf one?

Off-the-shelf CRMs work well for simple, standard sales funnels. A custom system makes sense when your process has extra steps, data lives in spreadsheets beside the CRM, per-user fees keep rising or integrations keep breaking. We compare both options honestly in our guide custom lead management software vs CRM.

How long does it take?

A focused lead management system typically takes 4-8 weeks. Larger CRMs with many integrations take longer; you get a timeline with the fixed quote.

Can you migrate our existing leads and customers?

Yes. We import data from spreadsheets or your current CRM, clean duplicates and map it to the new structure before go-live.

Do you work with clients outside India?

Yes. We work with clients in the UK, the EU, the USA and Malaysia, and quote and invoice in USD, GBP, EUR or INR.

Who owns the software?

You do. Once the project is paid, the source code, database and all data belong to you.
