Recurring billing for Dammam's contractors, rental firms and service providers.

We build subscription billing software for Eastern Province businesses that earn on a cycle: maintenance and facilities contractors, equipment and vehicle rental firms, industrial service providers in Dammam's industrial cities, and the gyms, schools and compound services across Dammam, Al Khobar and Dhahran. Contracts, recurring charges, usage, ZATCA invoices and payments are managed in one system that belongs to you.

Dammam has comparatively few consumer subscription startups. Most recurring revenue here comes from service contracts with industrial and corporate clients, so this page speaks to them first. Discovery and reviews run by video call, with our nearest team based in Riyadh. If you run a consumer membership business in the city, the same platform covers that too.

Built for
Facilities management, maintenance, rental and industrial service companies in Dammam, Al Khobar, Dhahran and Jubail, plus local membership businesses.
Typical timeline
Dates are set once discovery has mapped your contract types and existing systems, and they are written into the scope before any design work starts.
What you own
Source code, contract and billing data, integration credentials and ZATCA onboarding, all registered to your company.

What we build

Billing features built around Eastern Province service contracts.

A maintenance contract for a plant in Dammam's Second Industrial City does not bill like a streaming plan. It has a fixed monthly fee, call out charges, spare parts at cost plus margin, penalties if response times slip, and a purchase order that can run out before the contract does. Rental firms add daily and monthly rates, damage charges and off hire dates. Many service companies run all of this through an ERP that handles the accounting but not the recurring logic, so someone rebuilds invoices by hand every month. The capabilities below take that logic out of spreadsheets. Our subscription billing software developers plan them around contracts, sites and assets rather than a consumer checkout, and we only build what your contracts actually use. Contracts with energy companies and other large industrial clients often follow strict invoicing formats, and the system can hold a template per client so each one receives exactly the layout its accounts payable team requires.

Explain your project
  • Client, site and asset hierarchy

    One client can hold several contracts across Dammam, Jubail and Ras Tanura sites, each with its own scope, rates and PO. The system models client, contract, site and asset separately, so every invoice reaches the right cost owner inside a large organisation. Moving a site between contracts keeps its history intact.

    Invoices that match how large clients allocate cost.

  • Fixed fee plus variable charges

    A monthly or quarterly service fee combined with call outs, overtime, materials and extra visits, each priced from the rate card attached to the contract. Approved field records feed the variable lines automatically instead of being copied across. Rate cards can carry different prices for normal hours, nights and Fridays.

    Every chargeable visit reaches the invoice.

  • Field technician app

    Technicians log visits, time on site, parts used and photos from their phones, with the client's signature at the end of the job. Those records become the evidence behind each invoice line, available to finance and to the client. Job sheets can be printed or emailed to a client's site supervisor for countersignature where they prefer paper.

    Fewer disputes because proof sits next to the charge.

  • Equipment and vehicle rental billing

    Daily, weekly and monthly rates, minimum hire periods, on hire and off hire dates, fuel and damage charges, and automatic switching to a monthly rate when a short hire runs long enough to qualify under the contract. Assets returned early trigger a recalculation under the contract's minimum hire terms.

    Rental invoices that follow the contract without manual checks.

  • Purchase order tracking

    Each contract tracks its PO value and what has already been invoiced against it. Account managers receive an alert as the balance runs low, before the client's procurement system starts rejecting invoices and payments stall. Expiry dates on POs are tracked as well as values.

    No invoices stuck because a PO ran out.

  • SLA credits and penalties

    Where contracts include response time or availability commitments, the system calculates credits from logged job data and applies them on the next invoice, so the client sees the deduction already made rather than having to raise it. Credits are shown on the invoice with the job references that triggered them.

    Penalty clauses applied consistently and visibly.

  • Renewal and escalation tracking

    Contract end dates, notice periods and annual price adjustments are held per contract, with reminders to the account owner well before a renewal or a retender, and the agreed escalation applied automatically on the anniversary. Retender dates for government and semi-government clients can carry earlier reminders.

    Contracts renew on purpose, not by accident.

  • ZATCA clearance for B2B invoices

    Standard tax invoices pass through Fatoora clearance before they reach the client, with Arabic content, the client's VAT number and the QR code. Credit notes and debit notes follow the same route and stay linked to the original invoice. Rejected submissions are queued for correction rather than lost.

    Compliant invoices for every corporate client.

  • ERP and accounting sync

    Approved invoices and receipts post to the ERP your finance team uses, such as SAP, Oracle, Odoo or Business Central, through its supported interface, keeping receivables in a single ledger. Mapping between contract codes and ledger accounts is agreed with finance at the start.

    Billing detail and the general ledger stay aligned.

  • Client portal for contract holders

    Facility managers and procurement staff at your clients log in to see open jobs, signed job sheets, invoices, PO balances and statements of account for every site they manage. They can raise queries against a specific invoice line, which keeps disputes out of long email chains between Dammam and head office. Clients with many sites can download one consolidated statement each month.

    Clients answer their own questions and approve invoices sooner.

Who this is for

Four Eastern Province situations we build for.

The Eastern Province economy leans on energy, petrochemicals, ports and the contractors that support them, along with the families and expatriate staff who live across the Dammam, Al Khobar and Dhahran area. That shapes who needs recurring billing here. Below are the four groups we expect to hear from most, starting with the contract-heavy ones and ending with local membership operators. Jubail and Ras Tanura sit within reach of Dammam, so many contracts here span more than one town. Each group needs different first features, which is why we start with your contracts rather than a fixed package.

01

A facilities or maintenance contractor with many sites

You service buildings, plants or compounds under long contracts, and invoice preparation means gathering job sheets from supervisors, checking them against rate cards and typing them into the ERP. We connect a technician app to a contract billing core, so approved jobs flow into draft invoices that a finance user reviews and releases. Supervisors in Dammam can see which jobs are approved and which still lack signatures.

Finance keeps the final approval on every invoice.

02

An equipment, crane or vehicle rental company

Assets go out to projects in Dammam, Jubail and further afield, and rental days are counted from delivery notes and phone calls. We track each asset's on hire and off hire dates, apply the right rate automatically, and raise recurring invoices for long hires without anyone recounting days at month end. Off hire requests from site managers are logged with a time stamp, so the end date is never argued over.

03

A firm with clients on both sides of the causeway

Some Al Khobar businesses also serve customers in Bahrain, where tax rules and currency differ. We can set up separate billing profiles per country, each with its own tax treatment and invoice format, while keeping one customer record and one view of receivables for management. Bahrain customers can also receive invoices in a layout that suits their own accounts teams.

Bahrain tax treatment is confirmed with your adviser before build.

04

A gym, school or compound service with resident members

Residents of Al Khobar and Dhahran compounds pay for memberships, transport, activities or household services on a monthly cycle. We build member billing with automatic card renewal, family accounts and a simple app, sized for a local operator rather than a national chain with a large budget. Compound managers can see which families are active, paused or overdue at a glance.

How we build billing for a Dammam contractor or service firm.

  1. 01Contract review by video callWe go through a sample of your real contracts, rate cards, POs and disputed invoices with finance and operations, and list every charge type that appears.
  2. 02Billing modelClients, sites, assets, contracts and rates are modelled and agreed, including how variations, penalties and price escalations are calculated and approved.
  3. 03Field and operations captureTechnician and rental screens are designed for gloves, strong sunlight and weak signal, with offline capture that syncs when the device reconnects.
  4. 04Invoice engine and FatooraThe rating engine, approval steps and ZATCA clearance are built, then tested against last quarter's real invoices to prove the totals match.
  5. 05ERP connection and go liveInvoices and receipts sync to your ERP, then one client group goes live first while the rest stay on the old process for comparison.
  6. 06Contract changes over timeNew contract types, client portals and reporting are added through a retainer as your contracts, tenders and clients change.

Technology

What we build this with.

Field apps in Flutter with offline storage, a billing and rating engine in Laravel or Node.js on PostgreSQL, and ERP connections through each system's supported API or integration layer. Hosting can sit in a cloud region inside the Kingdom when clients ask where their contract data is kept.

Questions Eastern Province firms ask about contract billing.

The unit of billing is a contract and a site, not a user.

Consumer and SaaS billing revolve around plans and cards. Dammam service companies bill against contracts with rate cards, POs, field evidence and penalties, usually paid by bank transfer on terms. That changes the data model, the approval flow and the integrations, so we design around contracts from the first day instead of adapting a subscription template. The approval chain usually moves from operations to finance, with the field evidence attached at every step.
