How to keep your company's accounting without going crazy

Accounting is not the same as taxes

Many owners confuse "bookkeeping" with "paying taxes." They are related, but they are not the same. Accounting is the orderly record of everything that enters and leaves your business: sales, purchases, expenses, loans, salaries. Taxes are just a consequence of that registration.

When you do good accounting, taxes almost calculate themselves, because you already have all the information organized. When you don't have it, each declaration becomes a last-minute race looking for invoices in the mail, on WhatsApp and in drawers. The difference between both scenarios is not accounting talent: it is the habit of recording everything on time.

Think of it like this: accounting is for you first (to know how your business is doing) and for the SAT second. If you only see it as a tax obligation, you miss its greatest benefit, which is making better decisions.

First, identify your tax regime

In Mexico, how much and how you declare depends on your regime. You cannot do your accounting well without knowing which one you are in. The most common for SMEs and entrepreneurs are:

• RESICO (Simplified Trust Regime): low ISR rates on income, designed for individuals with income up to a certain limit and for SMEs. Very popular for its simplicity.
• Business and Professional Activity: for individuals who deduct expenses; more flexible in deductions but with more obligations.
• General Law Regime (legal entities): for companies incorporated as companies. Complete electronic accounting and more requirements.
• RIF (in extinction, but some are still in transit): tax incorporation regime for small taxpayers.

The documents that YES or YES you should keep

The SAT works with CFDI (electronic invoices). Your accounting is built on these receipts, so losing them is losing your tax support. Save in an orderly and backed up way:

• Revenue CFDI: every invoice you issue to your clients (the XML, not just the PDF).
• CFDI expenses: each invoice that your suppliers give you for what you buy. Without this, you cannot deduce.
• Payroll CFDI: the stamped receipts of your employees.
• Bank account statements: support for your money movements.
• Payment supplements (REP): when you collect or pay in installments or after the invoice date.

The basic method: record, classify, review

Accounting, in its simplest version, is a three-step cycle that you repeat constantly. You don't need to master double play to start in order:

• Record every movement when it happens, not months later. A sale, an expense, a payment: enter the system the same day.
• Classify each movement into a category: sales, cost of merchandise, income, salaries, advertising, services. The categories are what tell you where your money goes.
• Periodically review the reports: income statement (won or lost), balance sheet (what you have and what you owe) and cash flow (how much real money came in and went out).

Why centralizing everything in one place changes everything

The most common mistake of SMEs is having information scattered: sales on one side, invoices in the mail, expenses in a notebook, the bank in the app. When it comes time to declare or find out how much you earned, putting all that together is torture.

This is where a management platform saves you. At Aura, accounting does not live in isolation: it feeds itself on what is already happening in your business. Every sale you record generates its entry, every CFDI invoice you issue is linked, every expense you capture is classified, and the bank reconciliation module automatically balances the bank. When the end of the month comes, you don't build your accounting from scratch: it is already built.

That means you can see your income statement in real time instead of waiting for the counter to "close the month." And when your accountant comes in, instead of capturing everything, just review and validate. Less hours of capture, fewer errors, less stress. Accounting stops being the monster in the closet and becomes a board that you consult to decide.
