Step 1
Start from the approved estimate
The customer already said yes to the repair estimate — عرض سعر — written separately. Invoice Solutions does not generate that quote.
Business guide
The customer approved the estimate (عرض سعر), then the repair grew — extra labor, extra parts, a revised total. Issue a supplemental change-order invoice (تعديل / فاتورة) on the same shop ledger. Private web workspace — not an iPhone app.
Quick facts
A change-order invoice is a shop workflow: the estimate was approved, then scope grew mid-repair. Invoice Solutions does not add a separate change-order mode.
Job
Scope grew / تعديل
Approved estimate first (عرض سعر), then extra labor or parts discovered mid-repair — not a new customer or vehicle.
Ledger
Same job, extra lines
No change-order mode. Add the supplemental lines on the same job and finalize so the issued snapshot stays put.
Documents
EN / AR PDFs
English LTR or Arabic RTL فاتورة for the revised total, including تعديل.
Platform
Web workspace
Signed-in workspace for one shop owner. Not an iOS app.
Payments
Full or partial
Record the extra payment when it arrives. Reverse a mistake with a reason.
Change-order workflow
Step 1
The customer already said yes to the repair estimate — عرض سعر — written separately. Invoice Solutions does not generate that quote.
Step 2
When the job grows past the estimate, agree the revised scope (تعديل) before billing it. Do not treat the supplement as a separate customer or vehicle.
Step 3
Add the extra labor and parts as invoice lines on the same job. Totals calculate in cents. Finalize and the issued snapshot stays put.
Step 4
Full or partial. Download an English PDF or an Arabic RTL فاتورة for the revised total. Open or create the workspace from the Invoice Solutions product page.
Auto repair and mechanic shops know the moment: the customer approved the estimate, the car is on the lift, and the job grows — a seized bolt, a worn part behind the part, an extra hour of labor. That is a change-order invoice: a supplemental invoice (تعديل) for scope change after approval, on the same job.
Record and Learn Invoice Solutions keeps that record in a private web workspace: customers, vehicles, invoices, and payments. It does not invent a separate “change-order mode.”
Open or create the workspace from /en/invoice-solutions/. Pull up the same customer and vehicle — they stay saved. Add the supplemental labor and parts as invoice lines, finalize so the revised snapshot stays put, then record the extra payment.
Issued invoices stay put. Payments and reversals stay in history. That is the same ledger used for any shop invoice — not a second product and not a payment-processor checkout.
The same revised job can download as an English PDF or an Arabic RTL فاتورة, including the supplemental total (تعديل).
This page stays on scope change after approval — supplemental lines on the same job — not on deposits, not on parts-and-labor line setup alone, not on unpaid follow-up, and not on bilingual PDF layout.
It is not tax software, an accounting suite, or an inventory system. It is not an iPhone app. It does not add card checkout, a customer portal, SMS, or accounting sync.

FAQ
A change-order invoice — a supplemental invoice or تعديل — bills extra work discovered after the customer already approved the estimate. The scope grew mid-repair: extra labor, extra parts, a revised total on the same job.
No. There is no separate change-order or supplement mode. Use the same invoice ledger: add the supplemental labor and parts as invoice lines on the same job, finalize so the issued snapshot stays put, then record payment.
An estimate (عرض سعر) is the quote before approval. A deposit (عربون) is part of the job billed before work finishes. An unpaid reminder follows a balance that is already due. A change-order is scope growth after approval — a supplemental invoice for the extra work on the same job.
Yes. The same job can download as an English PDF or an Arabic RTL فاتورة, including the revised supplemental total (تعديل).
