To quote service and parts in a truck workshop, enter labor and parts in a single document that the customer authorizes and that moves to a work order without re-entry. That way you avoid different prices between the parts counter and the warehouse, parts that leave without being charged, and units sitting idle waiting for an answer. This guide shows what that document should include and how SITIC Software solves it in an ERP for heavy equipment.
Why does quoting in Excel or WhatsApp cost a truck workshop money?
Quoting in Excel, WhatsApp, or on paper costs money because every repeated entry opens the door to pricing errors, lost approvals, and parts that leave the warehouse without reaching the invoice.
A common case: the advisor sends the price of a brake pad set over WhatsApp, the customer replies “ok” among twenty other messages, and the technician starts the order without anyone confirming stock. At close, the part doesn’t match the one quoted, or nobody remembers who authorized the work.
The costs show up in three places:
- The advisor’s time, rewriting the same information in the quote, order, and invoice.
- Lost margin, from unrecorded parts or outdated prices.
- Units sitting idle, because the authorization gets lost in a conversation.
In operations running on paper, Excel, and WhatsApp, there’s no immediate answer to whether a part was recorded and invoiced.
What should a service and parts quote for trucks include?
A useful truck quote identifies the unit, separates labor and parts, confirms stock, and leaves a record of the customer’s authorization.
Unit and job details
- Customer, fleet, and the tractor’s fleet number or VIN.
- Mileage or operating hours at intake.
- Description of the work and labor by time, with the assigned technician or category.
Parts and approval details
- Part number, description, and quantity for each part.
- Stock at the branch or in another warehouse.
- Alternatives (original, equivalent, or rebuilt) with their price.
- Quote validity, because parts prices change.
- Customer authorization with date, time, and person responsible.
For labor, the most common logic is to multiply the estimated time by the cost of the labor hour. In trucks the times are different, but the logic of quoting by standard time is the same.
How do you go from quote to work order, parts issue, and CFDI invoice without re-entry?
You do it without re-entry when the quote, order, warehouse, and invoice live in the same system and each document inherits the data from the previous one.
The ideal flow has four moves:
- The customer authorizes the quote and the system converts it into a work order with the unit, parts, and labor already loaded.
- The order generates the parts request to the warehouse, which deducts the parts from inventory.
- The technician records time and any additional parts, and the customer approves changes before they’re carried out.
- When the order closes, the CFDI (Mexico’s electronic invoice) is issued for the work actually done.
If you also move units or goods, keep in mind that the SAT, Mexico’s tax authority, states that since July 17, 2024, only CFDI 4.0 with version 3.1 of the Carta Porte complement is valid. Having your ERP handle both avoids entering data on external portals.
What criteria should you use to choose the platform?
Choose a platform that connects quoting, inventory, and invoicing, and that understands how heavy equipment works, not just a car shop.
- Live inventory: the quote should show actual stock by warehouse and branch.
- History per unit: each tractor with its log, previous services, and accumulated costs.
- Quotes by fleet: prices and terms by customer, volume, or branch.
- Integrated invoicing: CFDI 4.0 from the closed order, and Carta Porte if you move units or goods.
- Direct support and follow-up: implementation, training, and service once the workshop is running.
- Industry processes: floor plan, manufacturer warranties, and serial number traceability without separate development.
Generic auto shop software usually covers the work order, but not always price lists by fleet, transfers between warehouses, or the import cost of parts. Ask yourself whether your operation needs that today or will need it when you open a second branch.
How does SITIC Software solve it?
SITIC Software handles the quote within its ERP: you send it by email or WhatsApp, the customer authorizes it in real time, and the work continues in the work order through to the invoice. It centralizes prospects, quotes, and follow-ups so they don’t get lost in a chat.
An example with a clutch and brake pad job on a tractor:
- The advisor selects the customer and the fleet number; the unit’s history appears instantly.
- They enter the mileage and add labor for the clutch and the brake pads by time.
- They search for each part by part number, see stock by warehouse, and offer alternatives.
- They send the quote by email or WhatsApp and receive the customer’s authorization in the system.
- The authorization stays on the same work order, a technician is assigned, and the warehouse issues the parts.
- When the order closes, the system generates the CFDI with labor, parts, and additional services.
Because SITIC Software is an ERP built for heavy equipment distributors, workshops, and parts distributors, the same system keeps the real cost of the order and the inventory. Management sees that visibility too.
Frequently asked questions
Does it work if you service fleets?
Yes. SITIC handles price lists by customer, volume, branch, or channel, and a log with accumulated costs per unit. There’s no limit on branches: each one operates with its own access, and management sees everything consolidated.
How long does implementation take?
The average is 12 weeks, with a dedicated team from your company that keeps to the schedule. The time varies with size, information, and processes. The cost depends on users, modules, and branches, and comes as a personalized, no-commitment proposal after a no-cost review call.
How do you migrate from Excel?
The implementation includes data migration, training, and adjustments. Your customer, unit, and parts catalogs move into the system, and if you ever want to leave, you can export your historical information to Excel.
