Why After-Sales Service Needs Its Own Process
For companies that sell appliances, equipment, vehicles or HVAC systems, the invoice is where the paperwork ends and the real relationship begins. Six months later the customer calls because the AC is not cooling. Three years later they need a part for a generator. Somewhere in between they want to know whether the unit is still under warranty. In many businesses each of these calls triggers the same scramble: customer service digs through archived invoices, the technician has no idea what was replaced last time, and finance cannot tell whether the visit should be billed or charged to warranty.
That disorder costs money in two ways. Directly, through free parts fitted to units whose warranty expired, service visits that never get invoiced, and manufacturer claims that are never filed. Indirectly, through customers who leave and tell others why. A structured after-sales operation turns this from an uncontrolled cost into an activity with visible revenue, cost and margin.
This guide covers the building blocks of after-sales and warranty management, the Saudi regulatory points your process has to respect, how warranty is accounted for, the KPIs worth tracking, and how an ERP ties the sale, the serial number, inventory and billing into one flow.
What After-Sales Actually Includes
- Installation and commissioning for products that need it. This is where the unit's service record starts.
- Standard warranty: a commitment to repair or replace the product if a defect appears within a set period.
- Extended cover after the standard warranty ends, sold for a fee.
- Annual maintenance contracts: scheduled preventive visits and agreed response times, with or without parts.
- Paid repairs for out-of-warranty faults or excluded causes such as misuse.
- Spare parts and consumables: filters, oils, batteries and wear parts.
Each has different economics. Standard warranty is a cost. Maintenance contracts are revenue earned over the contract term. Paid repairs and parts are immediate revenue. Lumping them into one "maintenance" account makes it impossible to know whether after-sales makes or loses money.
The Saudi Regulatory Points to Build Around
This is not legal advice, but your process should be able to support the following:
- Warranty period. The Ministry of Commerce has stated, as reported by Saudi Gazette, that electrical appliances, electronics and vehicles should carry at least a two-year warranty, extended where maintenance or a replacement part is delayed. The Ministry also published a draft Consumer Protection Law in March 2022 that includes a two-year statutory warranty. Confirm the current position for your product categories with counsel.
- Agent and distributor obligations. Under the Commercial Agencies Law and its regulations, agents carry obligations on maintenance, spare parts and quality guarantees, some of which continue after the agency ends until a replacement is appointed. Our article on exclusive agencies and distributors in Saudi Arabia covers this in more depth.
- Extended warranties. In October 2025 the Ministry of Commerce warned car dealers and consumer goods sellers against offering "extended warranty" products without a licence from the Insurance Authority. If you plan to sell extended cover, establish first whether it must go through a licensed insurer or be structured as a service contract.
- E-invoicing. Every paid repair, part sale or maintenance contract needs a ZATCA-compliant tax invoice with 15% VAT. Credit notes for returns follow the path of the original invoice type: cleared in real time for standard invoices, reported within 24 hours for simplified ones.
A Digital Record for Every Unit Sold
Everything starts with linking each unit to its customer. When the phone rings, the agent should see within seconds:
| Group | Data |
|---|---|
| Identity | Serial number, model, batch, manufacturing date where available |
| Sale | Customer, invoice number, sale date, branch or distributor, installation date |
| Coverage | Warranty start and end, covered components, exclusions, any maintenance contract |
| Service history | Every visit, fault, diagnosis, parts replaced, technician, time to fix |
| Financials | Amounts billed, warranty cost, manufacturer claims and their status |
That record is built at the point of sale, not afterwards. Serial numbers should be captured when goods are issued or delivered, not typed later from a delivery note. Businesses that work with production lots also benefit from batch tracking, so that if a lot turns out to be defective, every affected unit and customer can be listed in minutes.
When does the warranty start?
It sounds trivial and causes endless disputes. Invoice date, delivery date or installation date? And if a distributor sells a unit eight months after receiving it from the agent, does the end customer's warranty start from the distributor's sale? Write the rule down and let the system apply it. A common approach for distributor sales is end-customer registration through a code on the unit, which activates cover from the registration date.
The Service Request, Start to Finish
- Intake by phone, email or portal, linked immediately to the serial number.
- Coverage check: in warranty, under contract, or billable? The answer sets the work order type.
- Scheduling by area, skill and the response time promised.
- Diagnosis and repair: the technician records fault, parts and time; parts are issued from the van stock or the warehouse.
- Billing or charging: billable orders become invoices, warranty orders are charged against the warranty provision, contract orders are logged against the contract.
- Manufacturer claim: for supplier-covered defects, a claim is raised with evidence: serial number, photos, diagnosis and the replaced part.
- Close and survey: a short rating request, with immediate escalation of poor scores.
Keeping the customer informed
Customers want to open a request however suits them and then know where it stands without calling again. Give one reference number that follows the request everywhere. Send a message at each stage: received, visit booked with the technician's name, closed, rate us. And promise realistic windows. "Within two days" kept beats "today" missed. In summer, when AC calls surge, tell customers the expected response time up front and prioritize critical cases such as elderly customers and healthcare sites.
Spare Parts: Stock the Right Things
Waiting for parts is the main reason repairs drag on. The fix is not stocking everything, it is stocking correctly:
- Map every part to the models that use it, so technicians know what to carry before the visit.
- Base stock levels on actual consumption from repair history, not on supplier suggestions.
- Treat each technician's van as a sub-warehouse with its own balance and periodic counts.
- Plan for the season. AC failures in the Kingdom climb with summer heat, so compressors and capacitors should be positioned weeks before the peak.
- Separate parts used under warranty from parts sold, so the true cost of warranty is visible.
Accounting for Warranty
Standard warranty as a provision
A warranty that only assures the product works as specified is usually accounted for as a provision under IAS 37, recognized at the time of sale based on experience. A hypothetical example: a company sells 10,000 AC units this year. History shows 3% need a warranty repair at an average cost of SAR 400. The provision is 10,000 × 3% × 400 = SAR 120,000, expensed in the period of sale, with actual repair costs charged against it as they occur. Profit on the sale is then stated honestly, instead of looking inflated in year one and taking the hit in year two.
Service contracts as deferred revenue
Cover sold separately, or cover that provides a service beyond assurance, is a distinct performance obligation under IFRS 15, recognized over the service period. A SAR 2,400 contract for 24 months earns SAR 100 a month, and the remainder sits as a contract liability. Booking the whole amount on collection inflates that month and hides a real obligation to the customer.
Manufacturer recoveries
When an agent pays to fix a manufacturing defect and then recovers part of the cost from the manufacturer, the recovery should be matched against the cost. Many companies quietly absorb defects they are not responsible for because claims are never filed, or are filed without the evidence the manufacturer requires and rejected.
What After-Sales Really Earns: A Worked Example
A hypothetical HVAC agent with 25,000 units in the field separates its after-sales accounts for one year:
| Line | Revenue (SAR) | Direct cost (SAR) | Margin (SAR) |
|---|---|---|---|
| Paid out-of-warranty repairs | 900,000 | 540,000 | 360,000 |
| Parts and consumables | 1,400,000 | 910,000 | 490,000 |
| Maintenance contracts (earned portion) | 1,100,000 | 720,000 | 380,000 |
| Warranty repairs | 0 | 480,000 | (480,000) |
| Manufacturer recoveries | 0 | 210,000 recovered | 210,000 |
| Total | 3,400,000 | 2,440,000 net of recoveries | 960,000 |
Before the split, all of this appeared as one large, vague maintenance expense. After it, management can see a profitable activity, and can see that lifting manufacturer recoveries from roughly half to two thirds of defect cost adds straight to profit without a single new sale.
KPIs Worth Tracking
| KPI | Formula | What it reveals |
|---|---|---|
| First-time fix rate | Requests closed on first visit ÷ all requests | Technician readiness and parts availability |
| Mean time to repair | Request opened to request closed | Scheduling and parts supply |
| Warranty cost to sales | Warranty cost ÷ product sales | Product and supplier quality |
| Manufacturer recovery rate | Recovered ÷ cost of manufacturing defects | Claims discipline |
| Contract renewal rate | Renewed ÷ expiring contracts | Customer satisfaction with service |
| Repeat fault rate | Units back with the same fault within 30 days | Repair quality |
Reading failure patterns
Suppose an HVAC company analyzes 1,800 warranty requests in a year and finds that 38% involve one model, that most of those are compressor failures between months 14 and 18, and that coastal branches see twice the rate of inland ones. That gives three decisions: a consolidated, evidence-backed claim to the manufacturer, extra compressors stocked at coastal branches, and a review of installation practice or humidity protection. Without a structured record, those patterns stay as stories technicians tell each other.
Maintenance Contracts as Recurring Revenue
| Tier | Preventive visits | Breakdown response | Parts |
|---|---|---|---|
| Basic | Two a year | Within 48 hours | List price |
| Standard | Four a year | Within 24 hours | Agreed discount |
| Comprehensive | Monthly | Hours for critical faults | Included up to a cap |
The tiers are illustrative. What matters is that the system knows exactly what each contract covers, so nobody is billed for something included and nobody gets free service they have not paid for. For planning preventive visits systematically, see our guide to preventive maintenance. A simple, effective habit: an automatic prompt two months before standard warranty ends, offering a maintenance contract to customers who already used the service.
A Phased Rollout
- Weeks 1 to 3: write the warranty policy per product family, load units currently under warranty with serial numbers and customers.
- Weeks 4 to 6: define work order types, link parts issues to work orders, set up the warranty provision and deferred contract revenue accounts.
- Weeks 7 to 9: set up van stock as sub-warehouses, train technicians to record diagnosis, parts and time on site, standardize the evidence pack for manufacturer claims.
- Weeks 10 to 12: switch on KPI reports, run the first failure analysis, start a monthly review with service, warehouse and finance.
How an ERP Holds It Together
After-sales is not a separate system. It extends sales, inventory and accounting. With all of them in one place, serial numbers are captured at delivery and tied to the customer and invoice, parts are issued against the right work order, paid repairs become e-invoices, and warranty cost and contract revenue land in the right accounts without manual adjustments.
Tranquil provides customer management, sales with quotes, invoices, delivery and returns, inventory management, and ZATCA e-invoicing for Phase 1 and Phase 2, along with customization services for screens, reports and multi-level approvals to fit your service flow.
Frequently Asked Questions
How does the system tell warranty work from billable work?
At intake it checks the serial number against the warranty start date, period and exclusions. Covered jobs become warranty orders charged to the provision. Expired or excluded jobs get a quote before work starts.
Can we sell extended warranties directly to customers?
In October 2025 the Ministry of Commerce warned against selling extended warranty products without an Insurance Authority licence. Check how your offer is classified before launching it; a paid service contract is not the same as an insurance product.
How is warranty cost accounted for?
Standard assurance warranty is normally a provision recognized at sale under IAS 37. Extended cover or service contracts sold separately are recognized as revenue over the service period under IFRS 15.
Which KPI should we start with?
First-time fix rate. It reflects technician readiness, parts availability and diagnosis quality at once, and improving it cuts cost and lifts satisfaction together.
