Comparing accounting service costs only by the monthly fee often becomes expensive. A cheap proposal may not include CFDI review, returns, payroll, SAT responses or reports. A higher proposal does not guarantee quality if it does not explain deliverables.
The right comparison starts with scope, risk and clarity.
What a Clear Quote Should Include
- Tax regime and type of taxpayer covered.
- Approximate number of movements, CFDI, bank accounts and employees.
- Returns included and returns outside scope.
- Monthly deliverables: acknowledgments, workpapers, reports and pending items.
- Response time and communication channel.
- Cost of additional services: amended returns, requirements, payroll, refunds or special advisory.
Practical Comparison
| Element | Low price without scope | Clear price with scope |
| Returns | Says included, without listing which ones | Lists obligations, periods and owners |
| CFDI | Only downloads or captures | Reviews issued, received, canceled and differences |
| Reports | Does not specify deliverables | Delivers acknowledgments, summary and pending items |
| SAT | Requirements charged separately without process | Defines attention, timing and extra cost |
| Communication | Answers when available | Has channel, owner and calendar |
Warning Signs
- They promise a monthly fee without asking about the business.
- They do not explain what happens if a SAT requirement arrives.
- They do not deliver acknowledgments or workpapers.
- Everything is extra, but prices and triggers are unclear.
- They minimize CFDI, bank or return differences.
How to Decide Without Overpaying
You do not need the most expensive service if your operation is simple. But you do need to pay for the level of control your business requires.
An individual taxpayer with few movements does not need the same scope as a company with payroll, several bank accounts and high CFDI volume. The question is not only "how much does accounting cost?" It is "what risk does this scope leave unattended?"
How to Read a Fee Proposal
| Proposal line | What to ask before accepting |
| Fixed monthly fee | What movement and CFDI volume does it include? |
| Returns included | Which obligations, periods and acknowledgments are covered? |
| Advisory | How many questions, through which channel and with what response time? |
| SAT requirements | Are they charged separately and how is the file prepared? |
| Cleanup work | Does it include prior months or only future operations? |
What Should Not Be Missing Even at a Low Price
- Acknowledgments after each filed return.
- Pending list with missing documents or clarifications.
- Formal communication channel for questions and deliverables.
- Basic tax explanation, not only payment line.
- Workpapers stored so each period can be reconstructed.
If a low-cost proposal excludes all of that, you may not be buying full accounting. You may be paying for minimum capture. That can be enough in some cases, but it should be explicit.
How Fintax Can Help
Fintax can review your situation and propose a clear scope: what is included, what is not included, which deliverables you receive and when extra tax support makes sense. That lets you compare with information, not loose promises.
