Leads tracked in personal phones and sheets
Enquiries from the website, calls, portals and walk-ins are recorded inconsistently. When a salesperson leaves, their leads and history leave with them.

- Inventory and purchasing
IN PLAIN LANGUAGE
CRM & ERP Development, explained simply.
A CRM (customer relationship management system) tracks everything before and around a sale: where leads come from, who is following up, what was quoted and what the customer said. An ERP (enterprise resource planning system) runs the operations behind the sale: orders, stock, purchasing, production, dispatch and the records finance needs. Many growing businesses need parts of both, connected so a won deal flows into an order without being re-typed.
Ready-made CRM and ERP products work well for many companies. A custom build becomes worth considering when your process does not fit their structure, when license costs per user become significant, or when you need the system to connect tightly with other software you own. Custom does not have to mean building everything. It can mean a focused set of modules that match your workflow and integrate with tools you keep, such as your accounting software.
We deliver in phases. A first release might cover lead capture, pipeline stages and follow-up reminders for the sales team. A later phase adds quotations and orders, then inventory and purchasing. Each phase goes live, gets used and feeds lessons into the next, which keeps risk low and lets your team shape the system as it grows.
PROBLEMS IT SOLVES
Why businesses invest in it.
Quotations created from old files
Sales staff copy last month's quote and edit it, so pricing, taxes and terms are inconsistent and approvals for discounts happen informally.
Stock numbers nobody trusts
Inventory lives in a spreadsheet updated at the end of the day, so sales promise items that are out of stock and purchasing reorders too late or too much.
Approvals with no trail
Discounts, purchase orders and credit limits are approved over WhatsApp or verbally, which makes it hard to check who approved what later.
Reports assembled by hand
Monthly sales, pending orders and receivables are compiled from several sheets, and different people produce different numbers for the same question.
IS IT RIGHT FOR YOU?
Who needs it, and when.
Who it is for
- Growing trading, distribution and manufacturing businesses running on spreadsheets
- Service companies with a structured sales cycle and recurring clients
- Businesses that tried a ready-made CRM or ERP and found it a poor fit
- Organizations that need several departments working from one set of records
When it is the right time
- Spreadsheets are shared by many people and errors or version conflicts are common
- Management cannot get a reliable view of pipeline, orders or stock without asking around
- Your process has specific steps that ready-made software forces you to work around
- Per-user license costs or customization limits of an existing product are becoming a problem
WHAT'S INCLUDED
Features, deliverables and capabilities.
Scope is agreed in writing for every project. These are the building blocks we typically plan with you.
Lead capture and pipeline
Leads from website forms, ad campaigns, calls and portals in one list, with source tracking, assignment rules, pipeline stages and follow-up reminders.
Quotations and approvals
Quotes built from a product and price master with tax calculation, discount limits by role, approval routing and PDF generation in your format.
Orders and dispatch
Conversion of an accepted quote into a sales order, delivery scheduling, partial dispatch tracking and order status visible to sales and operations.
Inventory and purchasing
Stock by item and location, inward and outward entries, reorder levels, purchase requests, purchase orders and goods receipt against each order.
Roles, permissions and audit trail
Screens and data limited by role, such as salesperson, manager, store keeper and accounts, with a history of who changed what.
Reports and dashboards
Pipeline by stage, conversion by source, pending orders, stock levels and receivables, with filters and exports for management review.
Data migration from spreadsheets
Cleaning, de-duplicating and importing customers, products, open orders and stock from existing sheets, with validation reports before go-live.
USE CASES
How businesses use it.
Representative examples of the work, described generically. They are not client case studies.
Distributor sales and order system
Field sales record dealer visits and orders on mobile, office staff confirm against stock and credit limits, and dispatch is planned from the same screen.
Manufacturer quotation to production flow
A custom quotation with specifications is approved, converted into a work order, and material requirements are checked against inventory before production starts.
Real estate sales CRM
Enquiries from property portals and ads are assigned to sales staff, site visits are scheduled, and bookings are tracked against unit availability.
Service company client and contract tracker
Clients, contracts, renewal dates and service visits are tracked together, with reminders before renewals and a history of every interaction.
Multi-branch inventory control
Stock is tracked across warehouses and branches, transfers between locations are recorded, and purchasing sees consolidated reorder needs.
DELIVERY PROCESS
How we deliver it.
Decisions stay visible, important workflows are validated early, and delivery is shaped around the agreed scope.
- 01
Map how work flows today
Interview each role, collect the sheets and forms in use, and document the steps, approvals and exceptions from lead to delivery.
- 02
Design the data and phases
Define core records such as customers, products, orders and stock, agree on roles and permissions, and split the scope into deliverable phases.
- 03
Prototype key screens
Review clickable designs of the most-used screens with real users so layout and fields match their daily work before development.
- 04
Build, migrate and test a phase
Develop the phase, import cleaned data, test with real scenarios and train users, then go live with support during the first weeks.
- 05
Review usage and plan the next module
Check adoption and feedback, fix friction points, and confirm the scope of the next phase based on what the business needs most.
DECISION GUIDE
Ready-made, customized ready-made, or custom-built CRM and ERP?
Each route can be the right one. The decision depends on how standard your process is, how many users you have and how much control you need over the software.
Ready-made CRM or ERP
Best for: Businesses with standard processes that can adapt to how the software works.
Fastest to start, with features already built and updates handled by the vendor. You pay recurring per-user fees and accept the product's structure, and some workflows may need workarounds.
Customized ready-made system
Best for: Businesses whose process mostly fits a product but needs extra fields, automations or integrations.
Keeps the vendor's core while adding custom fields, scripts or connected apps through the product's APIs. It balances speed and fit, but heavy customization can be hard to maintain through vendor upgrades.
Custom-built system
Best for: Businesses with distinctive workflows, many users, or a need for full ownership of software and data.
Designed around your exact process and owned by you, with no per-user license. It takes longer upfront and needs ongoing maintenance, so a phased approach starting with one module keeps it manageable.

PLANNING
Considerations, cost and timeline.
Limitations & implementation considerations
- A custom system is only as good as the process behind it. Time spent agreeing on how work should flow is part of the project, not a delay.
- Data migration from spreadsheets often reveals duplicates, gaps and inconsistent formats, and cleaning it needs input from your team.
- Adoption needs leadership support. If old spreadsheets continue in parallel for too long, the new system will not become the single source of truth.
- Custom software has ongoing costs for hosting, maintenance and improvements, which should be compared against license fees of ready-made options.
What affects cost
- Number of modules and the depth of each workflow
- Number of user roles and permission rules
- Volume and condition of data to migrate
- Integrations with accounting, payment and messaging systems
- Need for a mobile app for field staff
- Reporting requirements and number of custom reports
Typical timeline
A focused first module, such as lead management or quotations, typically takes several weeks depending on scope. A fuller CRM and ERP covering several departments is usually delivered in phases over a few months.

FAQ
Questions about crm & erp.
Should we build a CRM or an ERP first?
It depends on where the pain is. If leads and follow-ups are slipping, start with CRM. If orders, stock and purchasing are the bottleneck, start with the ERP modules. A phased design lets both connect later without rework.
Can you move our existing Excel data into the new system?
Yes. We map your sheets to the new data structure, clean duplicates and inconsistent entries with your team's help, and import them with validation reports. Open orders and current stock are usually migrated just before go-live.
Will the custom CRM work with our accounting software?
Often yes, depending on what your accounting software supports. Many products offer APIs or import formats for invoices, customers and payments. We confirm the available method early, because it affects the design.
Can our field sales team use it on their phones?
Yes. The web system can be built to work well on mobile browsers, or a mobile app can be added for features like offline order entry, location check-ins or photo uploads.
Who owns the software and data after it is built?
Ownership terms are set out in the proposal and agreement. Typically the client owns the custom code and all business data, while third-party services used by the system remain under their own licenses.
