It needs an ERP with accounting integrated with inventory, workshop, and invoicing, because accounting-only software forces you to re-enter sales, parts, and service. That double entry is where the numbers stop adding up. This guide helps you decide among the three categories of tools that accountants and directors compare today.
Why is a machinery distributor’s accounting different from a regular retailer’s?
Because a single operation mixes unit sales, down payments, parts, and service, and each part leaves a different accounting record. A regular retailer sells and collects. You sell a tractor with a serial number, collect a down payment weeks before delivering it, and finance the balance.
These are the particularities that intersect in accounting:
- Units identified by serial number, with their own cost and margin.
- Down payments invoiced before delivery.
- Accounts receivable on terms, with due dates and payment complements.
- Parts that leave the warehouse for a workshop order or a parts counter.
- Labor, parts, and manufacturer warranties tied to the same work order.
If each of these lives in a different spreadsheet or system, the month-end close depends on someone reconciling everything by hand. If you also handle floor plan, read why floor plan and accounting don’t match.
Is accounting software enough, or do you need an ERP?
Accounting-only software is enough if your operation comes down to recording invoices and filing taxes. When you sell units, run a workshop, and manage parts inventory, you need an ERP. There are three categories.
Basic accounting
It covers journal entries, electronic accounting, and banks, with systems like those from CONTPAQi. Its limit is that the workshop and inventory are left out.
Adaptable generic ERP
It covers sales, purchasing, and inventory for many industries, like Alegra ERP or SAP Business One. Floor plan, workshop orders, and serial number traceability usually require additional configuration. Here we compare a generic ERP with a specialized one.
Industry-specific ERP
It’s built around heavy equipment processes. This is the category where accounting is fed by what happens in the workshop, the warehouse, and unit sales.
What should the system record so accounting balances without re-entry?
Accounting should be fed by each operation, without anyone re-entering it. This is the criterion that separates a good system from one that only issues invoices.
- CFDI 4.0 (Mexico’s electronic invoice) with payment complement, tied to down payments and collections on terms.
- Automatic journal entries from sales, purchasing, and inventory.
- Costing per unit sold and per workshop order, with labor and parts.
- Bank reconciliation against recorded receipts and payments.
- Accounts receivable and payable with due dates.
- Tax calculation and electronic accounting ready for the SAT, Mexico’s tax authority.
The practical test: ask the vendor to show you, with a work order, how the invoice, the inventory issue, and accounting connect.
What questions should you ask any vendor before signing?
Ask questions that show how it works with your industry, not just which modules it has.
- Implementation: how many weeks does it take, and what does your team need to contribute?
- Migration: can customers, balances, inventory, and units be imported from Excel?
- Support: is there direct technical support after go-live and for branches?
- Customization: are floor plan, warranties, and serial numbers included, or are they separate development?
- Total cost: what do the license, implementation, training, and support add up to?
On investment, costs vary widely and get refined with a quote. Always compare the cost of the full first year; here we explain what makes up the real cost of a system.
How does SITIC Software solve this?
SITIC Software is an ERP for heavy equipment distributors, dealerships, workshops, and parts distributors. Workshop, parts, sales, administration, and accounting work in a single system, so information isn’t entered twice. Floor plan, manufacturer warranties, and serial number traceability are included, with no additional development.
An example flow with a tractor:
- You record the sale of the unit by serial number.
- You deliver the tractor and, if it’s on credit, the balance goes to collections with its due date.
- The customer comes back to the workshop: an order opens with technician, time, and parts.
- When the order closes, the system generates the CFDI 4.0 with labor, parts, and additional services.
- Inventory, invoicing, and accounting are updated in the same system.
The implementation includes data migration, training, and adjustments. The average is 12 weeks, and after go-live there’s direct technical support. The cost depends on users, modules, and branches, and comes as a personalized, no-commitment proposal.
A mini checklist for your decision:
- Is my accounting fed by sales, workshop, and inventory with no re-entry?
- Can I see the real cost of each order before invoicing?
- Can I migrate my data from Excel?
