Your accounting and your ERP,
finally in the same place.
A monthly accounting and tax retainer, 100% remote, running directly inside your Odoo V18 Enterprise with the Mexican Localization. Munin — an Odoo Silver Partner since 2016 — looks after your company's accounting, taxes, and payroll inside the same system you already operate in.
Is your accountant working in Contpaqi while your team operates in Odoo?
Does the monthly close take you weeks because of manual reconciliations?
Are you unsure whether your CFDIs actually match your accounting entries?
All of that disappears when your accounting lives inside Odoo. A single source of truth for sales, purchases, payroll, and taxes — no exports, no double entry, no discrepancies with the SAT.

The advantages of operating
inside Odoo.
Native accounting in Odoo V18 isn't just convenient: it's the only architecture that removes the risk of double entry, CFDI discrepancies, and slow closes all at once.
Real-time financial information
Because accounting lives inside the same ERP you operate in, your P&L, balance sheets, and cash flows are always up to date with no intermediate exports.
Reduced fiscal risk
Automated EFOS validation and the CFDI 4.0 audit against journal entries minimize discrepancies with the SAT before they turn into notices or formal requirements.
Zero double entry
Your operations team generates the accounting under our supervision. No parallel systems, no manual exports, no intermediate spreadsheets.
Infrastructure savings
A 100% remote, cloud-based service: no physical space, no additional licenses, and no dedicated headcount for the accounting function.
Peace of mind for leadership
A hybrid profile — an accountant with deep technical command of Odoo — looks after the financial "plumbing" of the system so leadership doesn't have to.
From diagnosis
to monthly operation.
Diagnosis
We review your current operation and Odoo environment: active modules, fiscal positions, configured journals, and the state of the Mexican Localization.
Tailored quote
We define the monthly scope based on transaction volume, the number of employees on payroll, and the complexity of your tax regime.
Onboarding
Initial setup on Odoo.sh: chart-of-accounts mapping, fiscal positions, bank reconciliation rules, and Mexican payroll configuration.
Monthly operation
A continuous monthly cycle: accounting close, tax filings, CFDI 4.0 validations, stamped payroll, and reports delivered directly in Odoo.
What clients ask
before they sign up.
Can I sign up if I use Odoo Community or a version older than 17?
+
This Odoo accounting and tax service is available only to companies running Odoo 17 or 18 Enterprise hosted on Odoo.sh, because that combination enables unlimited native CFDI 4.0 stamping, automated EFOS validation, and the direct connection to the SAT. If you currently use Odoo Community, an older version, or different hosting, Munin can help you migrate: book a call and we'll walk you through the process.
What happens to my historical accounting before migrating to this model?
+
Historical accounting stored in Contpaqi, COI, or another system can be imported into Odoo as opening balances or opening journal entries. During the diagnosis we determine how much history needs to migrate, what can stay available for reference in the previous system, and the most convenient cut-off date so that the go-live in Odoo V18 is clean and free of information gaps.
Does the service include the annual ISR return?
+
Yes. The monthly Odoo accounting retainer includes the calculation and filing of the annual ISR return for legal entities, the monthly provisional ISR and IVA payments, and the DIOT. The calculations are performed directly from Odoo V18 using the electronic accounting data for the full fiscal year.
Do you handle special payroll cases like commissions, bonuses, and severance?
+
Yes. Mexican payroll in Odoo V18 supports variable items such as commissions, bonuses, overtime, vacation premiums, and the calculation of severance and settlements. Receipts are stamped natively without an external PAC, and the bimonthly variation reports for the IMSS are generated in the TXT format required by IDSE and SUA.
What happens if the SAT sends me a formal request or invitation?
+
In-person handling of SAT and STPS audits, fines, or formal requirements is not included in the monthly retainer and is quoted separately. What we do provide is the accounting documentation the SAT requests — journal entries, XML, electronic accounting — in the correct format, directly from Odoo V18, so whoever handles the request has everything ready.
How is the service billed and what does the monthly price include?
+
The service is billed monthly as a retainer. The price depends on transaction volume, the number of employees on payroll, and the complexity of the company's tax regime. The quote is delivered after a free initial diagnosis. The monthly price includes every component of the scope described on this page — operational audit, accounting validation, taxes, DIOT, payroll, EFOS, reports, and unlimited stamps — with no additional charges.
What company size is ideal for this retainer?
+
The service is designed for Mexican companies with between 10 and 200 employees that already operate — or are migrating to — Odoo V18 Enterprise on Odoo.sh. The typical profile issues between 50 and 500 CFDI 4.0 invoices per month, runs biweekly or weekly payroll, and wants to eliminate the dependency on parallel accounting systems like Contpaqi or COI.
What if my Odoo.sh has technical incidents during the month?
+
Odoo.sh has a 99.9% availability SLA with automatic daily backups. As an Odoo Silver Partner with technical access to the Odoo.sh environment, Munin coordinates directly with Odoo support in the event of incidents that affect accounting operations, so the client doesn't have to escalate the tickets on their own.
