Services/Custom Software Development
AISDC designs and builds tailored accounting systems and integrations that fit the real workflows of your business or accounting firm. We connect your accounting with your operational systems, automate CFDI downloads and reconciliation from Mexico's SAT, and generate the reports and files required for fiscal compliance. We are not an off-the-shelf package — every solution is built around your specific processes and requirements.
We analyze your current accounting processes, the systems you already use (ERP, invoicing, payroll, banking), and the friction points: manual data entry, delayed reconciliations, CFDI mismatches, or reporting gaps. Together we define the real project scope.
We design the system or integration architecture: data flows, chart of accounts, reconciliation rules, required modules, and connections to external systems. We validate the design with you before writing a single line of code.
We build the custom system or connectors: SAT bulk downloads, automated bank reconciliation, integration with CONTPAQi, Aspel, or other packages, journal entry generation, and XML files for the SAT. We test with real data from your operation.
We deploy the solution to production, train your accounting and IT teams, and support the initial rollout. We provide technical support, adjustments for SAT rule changes, and system evolution as your needs grow.
Modules for entry, validation, and classification of journal entries against your company's chart of accounts, with configurable business rules and a full audit trail.
We automate the reading of bank statements and their reconciliation against your recorded accounting movements, reducing month-end close time and manual errors.
We connect to SAT's bulk download service to retrieve your issued and received electronic invoices (CFDI), and automatically reconcile them against your accounting and treasury records.
We generate balance sheets, income statements, cash flow statements, and custom reports in the formats required by your management, board, or auditors.
We connect your electronic invoicing and payroll systems to accounting so that transactions are recorded automatically, eliminating double entry and reconciliation errors.
We generate the XML files for the chart of accounts, trial balance, and journal entries in the format required by Mexico's SAT for electronic accounting submissions, adapted to your account structure.
A business with its own ERP, point-of-sale, or logistics system needs transactions to flow automatically into accounting. AISDC builds the connectors and classification rules so that month-end close no longer depends on manual exports.
A firm handling accounting for several companies may need a centralized platform to download CFDI, reconcile movements, and generate SAT reports and files for each client efficiently. AISDC designs that workflow around the firm's own processes.
Organizations with high invoice and transaction volumes that currently reconcile in spreadsheets can hand that process to a system that downloads, compares, and flags discrepancies automatically, freeing up the accounting team for higher-value work.
It is a system designed specifically for your company's or firm's accounting processes, rather than a generic off-the-shelf package. It can be a full system, a module that extends your current package, or integrations that automate flows between existing systems. The goal is for technology to adapt to your operation, not the other way around.
Not necessarily. CONTPAQi, Aspel, and similar tools are certified packages with validated accounting and tax engines. AISDC can integrate with them: extract data, feed information from other systems, automate reconciliations, or build complementary modules. If your operation requires a fully custom system for specific reasons, we build that too — but we honestly assess which approach makes more sense for each situation.
Yes. We connect to SAT's bulk download service to retrieve your issued and received CFDI, and automate reconciliation against your accounting records and bank statements. The system identifies discrepancies and generates alerts, significantly reducing manual work at close.
Yes. We can generate the XML files for the chart of accounts, trial balance, and journal entries in the format established by Mexico's SAT for electronic accounting, adapted to your company's account structure. We recommend having your accountant or auditor validate final compliance.
A standard package like CONTPAQi or Aspel is a good fit when your company's processes can adapt to their predefined workflows and the volume does not justify custom development. A tailored system or custom integration makes sense when you have differentiated processes, multiple systems that need to communicate, high transaction volumes requiring automation, or reporting needs that standard packages do not cover. AISDC helps you evaluate which path is right for your situation.
