Services/Custom Software Development
Every company has its own hiring schemes, benefits structures, and internal processes — off-the-shelf payroll systems rarely fit without friction. At AISDC we design and integrate custom payroll systems that adapt to your business rules, connect with the certified calculation engines already available in the market, and automate everything from earnings and deductions to CFDI stamping with Mexico's tax authority (SAT). The result is a reliable, auditable payroll workflow aligned with how your business actually operates.
We analyze your employment schemes, employee types, special benefits, and the systems you already use — ERP, time-clock devices, HR platforms — to define exactly what needs to be automated and which integrations are required.
We determine whether the best approach is integrating with a certified payroll calculation engine (such as CONTPAQi Nómina or Aspel NOI), building a fully custom system, or combining both. You receive a clear technical plan before any code is written.
We build the necessary modules: earnings and deduction calculations, connection to a PAC for CFDI payroll stamping, integration with time-clock and biometric devices, and connectors to banks or your ERP — all covered by unit and integration tests.
We guide validation alongside your payroll team, train end users, and deliver complete technical and functional documentation. Once live, we provide ongoing support to handle changes driven by tax law updates or evolving business needs.
Automated calculation of salaries, wages, overtime, bonuses, commissions, garnishments, and any concept specific to your company, respecting the business logic of each employment scheme.
Integration with Authorized Certification Providers (PAC) to generate and stamp the payroll Digital Tax Receipt (CFDI) in compliance with the SAT's current payroll complement, ensuring fiscal compliance for every pay slip.
Management of absences, tardiness, leaves, vacations, and sick days directly connected to payroll calculation. Compatible with biometric time-clock devices and existing access-control systems.
Calculation engines configured to current legislation for employer and employee IMSS social-security contributions, INFONAVIT housing-fund contributions, and income-tax (ISR) withholding, with file generation for IDSE and SUA.
Electronic issuance and distribution of stamped pay slips. A web or mobile portal lets employees view their receipts, income certificates, and incident status without depending on the HR department.
Generation of payroll reports, accounting provisions, and disbursement files in the formats required by major Mexican banks for mass employee payments, reducing manual errors and closing time.
Organizations with employees across multiple shifts, sites, or project-based contracts need precise attendance and incident tracking that feeds directly into payroll calculations. AISDC integrates time-clock devices or field apps with the payroll engine to eliminate manual data entry and reduce errors.
Firms that process payroll for several client companies need a multi-entity system that keeps data segregated, automates CFDI stamping, and generates IMSS and INFONAVIT files for each company. AISDC builds or adapts tools that fit that specific workflow.
Businesses that combine permanent employees, freelance contractors, outsourced workers, and interns face different calculation rules within a single payroll run. AISDC designs systems that handle each scheme with its own logic and consolidates them into a single disbursement and reporting flow.
It is a system that automates the calculation, recording, and payment of employee wages and salaries, covering earnings, deductions, IMSS social-security contributions, INFONAVIT housing-fund contributions, ISR income-tax withholding, and the issuance of the digital tax receipt (CFDI de nómina) required by Mexico's SAT for every salary payment.
Yes. We integrate the system with one or more Authorized Certification Providers (PAC) so that each pay slip is electronically stamped with the SAT using the current payroll complement, fulfilling the legal obligation to issue a CFDI for every salary payment.
Yes. We configure the calculation engines in line with the current tables and rates set by Mexican law: employer and employee IMSS contributions, monthly or annual ISR withholding, and INFONAVIT contributions. Parameters are updated when legislation changes.
Yes. We can connect the system to the biometric or time-clock devices your company already uses to automatically import attendance records and calculate incidents. For payment, we generate mass disbursement files in the formats required by major Mexican banks.
It depends on your company's needs. In many cases the most efficient solution is to integrate and extend a certified payroll engine already available on the market — such as CONTPAQi Nómina or Aspel NOI — with custom modules that cover your specific processes. When requirements are highly particular, we build the system from scratch. In either case, we start with a discovery phase to recommend the option that best balances cost, timeline, and functionality.
