Home › Sectors › Customer and Invoicing Management

Are you struggling with paperwork clutter or difficulty tracking customers and invoices?
This system is designed specifically to organize and develop the operations of small and medium-sized businesses in a simple and professional way.

An integrated administrative and accounting platform that enables you to manage customers, contracts, electronic invoices, and payments,
with clear reports that provide accurate financial visibility and better control over your decisions.

Stronger organization, clearer accounts, and easier management — all in one system.

Why Customer and Invoicing Management?

Sales Pipeline with Custom Stages

Convert a lead into an opportunity with one click, and track it through stages you define yourself until it's won or lost.

Customer Follow-Ups with Tasks & Reminders

Attach a call, meeting, or task to any customer or deal, and the dashboard reminds you of anything due within the week.

Full Invoicing Chain, One Click at a Time

From quotation to sales order to delivery note to invoice — each document converts into the next with one click, no re-entry.

Returns with Reversing Accounting

Approve an invoice return and refund the customer, and the accounting entry reverses itself automatically.

One Receipt, Multiple Invoices

Receive a customer's payment and allocate it across several outstanding invoices at once — any leftover automatically becomes their account credit.

Automatic Accounting for Every Transaction

Every invoice, payment, or return posts as an automatic double-entry journal — the system verifies debits equal credits before saving.

Customer & Supplier Aging Reports

Know exactly who's late on payment and since when, and what you owe suppliers — with a ready-made aging report.

Multi-Branch Stock with Accurate Costing

Track every product's balance per branch separately, with a weighted-average cost that updates on every sale or purchase.

Purchasing, Request to Payment

Purchase request, order, goods receipt, supplier bill, and payment — with inventory and accounting always in sync at every step.

One Contact Record for Everything

A single contact (customer or supplier) holds their invoices, payments, and full communication history in one place instead of scattered spreadsheets.

Commercial Licenses with Auto Reminders

Log every license with its expiry date, and the system automatically alerts you 30 days before it expires — no manual tracking needed.

Real Automated WhatsApp for Invoices

The system sends an actual WhatsApp message via API when an invoice is issued or a payment is received — a real message, not a manual contact link.

Frequently Asked Questions about Customer and Invoicing Management

No. The 7-day trial is completely free and does not require a credit card or any payment details.

You create your account, use the full system, and decide at the end of the trial whether to subscribe. There is no automatic charge and no commitment.

Nothing is charged automatically. When the 7 days end, you simply choose the plan that fits your business to keep working.

If you decide not to continue, the account is not renewed and no payment is taken. You can contact us any time and we will help you decide which plan suits you.

Yes. Mazoon ERP is a cloud system that runs in the browser, so it works on mobile, tablet and desktop without installing anything.

You sign in with the same account from any device, and your data stays synced across all of them.

Yes. Your data is stored on secure servers, and a backup is taken every day.

Each business has its own separate workspace, and only the users you create can reach your data — each with the permissions you assign.

Yes. The full interface is available in Arabic and English, and each user can switch language from inside their own account.

This is useful when part of your team works in Arabic and another part prefers English.

Yes. The invoice is issued straight from the document that precedes it — the work order, the sales order, the booking or the contract — so its lines and prices arrive already set, with no re-keying and no forgotten item.

You can print it or send it to your customer, and it posts to your accounts at the same moment — which is what keeps month-end reports accurate without manual reconciliation.

The system also supports electronic invoicing requirements where they apply, issuing a tax invoice carrying your details and a QR code to the relevant authority's specification.

Updates are free. Every improvement and new feature added to the platform under its development plan reaches you automatically, at no extra cost and without you having to ask for it.

And because the system is cloud-based, there is nothing to install and no downtime — you sign in the next day and the update is already there.

This is the difference between a subscription and buying a program once: the system you use in two years will be better than the one you subscribe to today, at the same price.

Yes. Notifications are sent from a WhatsApp Business number registered to your own business — so your customers see your name, not ours, and the number stays yours.

We handle the whole setup for you: preparing the number, verifying it with WhatsApp, and linking the payment method inside your own account — a one-time fee of 25 OMR. There is no technical step left for you to do. After that it is 5 OMR per month to run and manage the service.

The cost of the messages themselves is billed to you directly by WhatsApp, based on what you actually send — we take nothing on top of it.

 

Once a quotation is approved you convert it into an invoice in one click: its lines and prices carry over unchanged, and the invoice journal entry is created automatically. A quotation converts only once, so the same invoice is never issued twice.

Yes. You make the invoice an instalment invoice with a schedule of amounts and due dates, and record each payment against its instalment, which becomes partly or fully paid. Every customer has a printable, exportable statement and an aging report, and a cheque payment is logged in the cheques register automatically.

The Basic plan starts at OMR 22 a month for three users, Professional is OMR 32 for fifteen users and Comprehensive OMR 42 for twenty-five users, and yearly billing costs less. You start with a full seven-day free trial, no card needed.
