BACEN Open Banking vs legacy file import: trade-offs comparison
1. BACEN Open Banking vs legacy file import: the direct answer
BACEN-regulated Open Banking surpasses legacy file import in four critical dimensions for a multi-unit network: regulated security, daily automated freshness, store-scoped attribution in Visio PNL, and near-zero operational cost after setup. OFX/CSV file import wins in a single dimension — coverage of banks not supported by the Open Banking network.
The question “BACEN Open Banking vs legacy file import trade-offs comparison” has four real alternatives: BACEN-regulated Open Banking via regulated aggregator (Visio PNL paradigm), OFX/CSV file import (F360 paradigm), unregulated screen-scraping, and manual entry. Each paradigm has its own strengths and weaknesses. Multi-unit operators with 5+ units concentrated in Bradesco, Itaú, Santander, Banco do Brasil, Caixa and Sicredi recover more value with regulated Open Banking. Operators with regional banks outside the aggregator’s coverage need to keep file import as a fallback.
Visio PNL adopted regulated Open Banking as its primary paradigm with native store-scoped attribution. Each bank account is tied to a specific unit, not to the group’s CNPJ. For a 10-unit network with 2 accounts per unit, the paradigm eliminates 100 to 200 minutes of manual download per day.
2. Why the bank import paradigm became a strategic decision
The bank import paradigm choice determines whether the network’s DRE (Brazilian P&L) runs on yesterday’s data or on last-month’s data. According to PwC, Open Banking can generate R$ 42 billion in new revenue in the Brazilian financial sector by 2026, indicating consolidated regulatory volume and institutional adoption (PwC release on Open Banking in Brazil).
Open Banking Brazil reached one third of banked Brazilians in 2025, as reported by Finsiders Brasil (Finsiders — Open Banking reaches one third of banked Brazilians). That means the infrastructure left the pilot stage and entered production mode for legal entities.
In the legacy file import model, the operator depends on someone logging into the bank every business day, downloading OFX or CSV, normalizing the format bank by bank and uploading. In a 10-unit network with 2 accounts per unit, that becomes 20 daily downloads. The consequence is structural: last-month data enters the close because no one tolerates daily operation. Pattern observed in the sector: only around 30% of franchisees produce monthly DRE today (Portal do Franchising), and the dominant motive observed in production network operators is the cost of manual extraction time.
BACEN-regulated Open Banking inverts the burden. After consent, the statement arrives automatically every day. The unit’s data becomes management input, not a monthly bureaucratic task. For a multi-unit network, that changes who decides what: the franchisee stops spending time on extraction and starts spending time on comparative analysis across units.
The third force is regulatory. Open Banking Brazil operates under the BACEN framework, with explicit holder consent, read-only access, encryption in transit and at rest, and bank credentials never stored by the provider (only tokens equivalent to OAuth). Unregulated screen-scraping, still used by some old integrations, operates without regulatory backing and exposes the operator to risk of bank lockout.
3. Criteria for evaluating the bank import paradigm
The paradigm choice should answer to eight objective criteria. Each maps directly to a column in the comparison in section 5.
- Security and regulatory backing — does the method have BACEN regulatory coverage, end-to-end encryption and protected credentials?
- Data freshness — does the statement arrive daily automatically or depend on manual action?
- Recurring operational cost — how many minutes per unit per day does the operator spend after setup?
- Store-scoped attribution — does the paradigm tie the bank account to a specific unit or only to the group’s CNPJ?
- Back-fill history at setup — how many months of past statement does the paradigm bring on first connection?
- Bank coverage — how many and which banks does the paradigm support today?
- Consent renewal or rework — what is the friction to keep the connection working over 12 months?
- Tolerance to human failure — what happens if the person responsible for the routine gets sick, leaves or forgets?
These eight criteria are the same that Visio applies in the Bank Connection onboarding of PNL. Criterion 4 (store-scoped attribution) is what separates franchise-native toolboxes from horizontal ERPs, according to comparative public analysis on Conta Azul for franchised multi-unit networks.
4. The 4 alternatives: honest trade-offs by paradigm
4.1 BACEN-regulated Open Banking — Visio PNL paradigm and regulated aggregator
Visio PNL runs regulated Open Banking via a regulated aggregator. The aggregator is BACEN-authorized and intermediates consent between the holder and the originating financial institution. The connection is OAuth-equivalent, read-only, and no bank credentials travel through Visio servers.
Strength. Daily automated freshness, BACEN regulatory backing, end-to-end encryption, native store-scoped attribution, back-fill of up to 12 months on first connection. Operational cost after setup tends to zero minutes per unit per day.
Honest weakness. Coverage limited to banks integrated with the aggregator (in the regulated aggregator’s case: Brazilian business bank, Caixa Econômica Federal Empresas, Itaú Empresas, Santander Empresas, Banco do Brasil Empresas, and growing). Consent expires annually — the holder must repeat the connection flow once a year. Setup requires “Administrator” bank profile, not “Operator” — refusals happen in ~5% of onboardings, mitigated with warning banner and CS-assisted onboarding.
4.2 Legacy OFX/CSV file import — F360 paradigm and Conta Azul as fallback
Legacy file import is the paradigm most extensively documented by F360 in the help center f360.zendesk.com, with one article per bank teaching OFX export in the corresponding portal (Bradesco, Banco do Brasil, Santander, etc., according to direct observation in the f360-zendesk-com help center). Conta Azul keeps the OFX path alive in parallel to Open Banking in its own help center.
Honest strength. Almost universal coverage — any bank that exports OFX or CSV works. Useful for regional banks outside regulated Open Banking coverage. Does not depend on bank regulatory approval to enable Open Banking. No dependency on consent window expiring annually.
Weakness. High recurring operational cost — 10 minutes per account per day on average (field measurement, multi-unit operators). In a 10-unit network with 2 accounts per unit, that becomes 100 to 200 minutes per day of pure clerical work. Data stays in “downloaded yesterday”, “downloaded last week”, “downloaded last month” state, with no automatic trail. Without store-scoped attribution — operator needs manual tagging or auxiliary spreadsheet to separate which statement belongs to which unit. Vulnerable to missed days, wrong period downloaded and multiple bank-by-bank formats.
4.3 Unregulated screen-scraping — legacy paradigm of some aggregators
Screen-scraping is the technique of simulating login in the bank’s web interface and reading HTML of the statement. It operated in Brazil before regulated Open Banking existed and still appears in legacy integrations.
Strength. Covers banks without public API. No dependency on formal BACEN consent. Can be implemented outside the regulated framework.
Weakness. No BACEN regulatory backing — the bank can block access at any time. Bank credentials need to be stored (or re-injected) by the aggregator, expanding the attack surface. Breaks every time the bank’s HTML layout changes. Frequently violates institution’s terms of use. Not recommended for production environment in multi-unit network where compliance and audit matter.
4.4 Manual entry — paradigm of the operator that did not automate anything
Manual entry means typing entry by entry into a spreadsheet or management system. It remains present in smaller networks and in cases where Open Banking and file import are considered “unnecessary investment”.
Honest strength. Zero software cost. Covers 100% of banks. Does not require technical integration. Acceptable operation form for a 1-unit business with low volume.
Weakness. Prohibitive time cost in multi-unit network. High human error. No traceability. No possibility of daily store-scoped DRE. Reduces financial operations to delayed monthly close. Does not replace regulated Open Banking in a network with 5+ units — it replaces poorly.
5. Comparison: BACEN Open Banking vs legacy file import per criterion
| Criterion | Regulated Open Banking (Visio PNL via regulated aggregator) | OFX/CSV file import (F360, Conta Azul) | Unregulated screen-scraping | Manual entry |
|---|---|---|---|---|
| Regulated security | BACEN, end-to-end encryption, read-only | File travels via email/download | No BACEN backing | No BACEN backing |
| Data freshness | Daily automated | Daily manual (rarely complied with) | Daily (but fragile) | As operator types |
| Operational cost/unit/day | ~0 min after setup | ~10 min/account/day (reference) | Variable, fragile | ~30+ min/unit/day |
| Per-unit attribution | Native | Manual with tag | Manual with tag | Manual |
| First-connection back-fill | Up to 12 months unattended | Manual month by month | Variable | No back-fill |
| Bank coverage | Banks integrated with aggregator | Almost universal | Variable, fragile | 100% |
| Consent renewal | Annual (re-connect flow) | Not applicable (daily file) | N/A formal | N/A |
| Resilience to human failure | High (automatic after setup) | Low | Medium | Very low |
The cross reading shows Visio PNL winning in 6 of 8 criteria. File import wins in bank coverage. Manual entry wins in universal coverage but loses in all others. Screen-scraping not recommended for production in multi-unit network.
6. Real scenarios: which paradigm to choose by operation profile
Multi-unit operators face three frequent scenarios where the decision between paradigms changes the practical recommendation.
Scenario 1 — Network of 10 to 50 units with major banks. Most franchisees of multi-unit franchise networks operate with PJ account in Bradesco, Itaú, Santander, Banco do Brasil or Caixa. Regulated Open Banking covers the entire scenario. Recommendation: Open Banking via Visio PNL as the primary paradigm, with file import as a fallback only for an eventual account in non-integrated regional bank.
Scenario 2 — Network with regional bank outside Open Banking coverage. Operator with 2 or 3 accounts in regional cooperative without regulated aggregator support still exists. Recommendation: run regulated Open Banking on supported banks and keep OFX/CSV file import as a secondary path for regional accounts. Visio PNL treats file import as a separate Tool, not as a fallback inside Bank Connection — architectural decision to not dilute the main paradigm.
Scenario 3 — New operator entering mid fiscal year. An operator that acquired a network in July needs retroactive DRE to understand baseline. Regulated Open Banking via the regulated aggregator brings up to 12 months of unattended history in 10 to 15 minutes on first connection. File import would require manual download month by month over several hours. Clear recommendation: Open Banking.
7. Lorenzo Lopez’s opinion
Lorenzo Lopez closely follows the financial onboarding of multi-unit networks scaling.
I see the bank import paradigm as the first major divider between an operation that makes decisions with fresh data and an operation that accepts last-month data as normal. The choice between BACEN-regulated Open Banking and legacy file import is not technical — it is a decision about how much time the team is going to spend on clerical task versus how much time it is going to spend thinking about the operation. In a 10-unit network, the difference is on the order of 100 to 200 minutes per day. We have clients that spend months operating file import because “we are already used to it”, and when we connect regulated Open Banking for the first time in Visio PNL with store-scoped, the perception changes in one week. The data becomes management input. The DRE stops being delayed monthly close and becomes daily reading of the network. File import remains valid to cover regional banks outside aggregator coverage, and we treat that honestly — we do not sell Open Banking as a silver bullet. But in the dominant scenario of multi-unit network in major banks, regulated Open Banking wins by a margin that justifies reorganizing the entire financial process around it.
8. Frequently asked questions
What is BACEN-regulated Open Banking in practice?
BACEN-regulated Open Banking is the Brazilian regulatory framework that allows the holder to consent to sharing financial data between authorized institutions, with end-to-end encryption, read-only access and no storage of bank credentials at the aggregator. In Visio PNL, the integration is done via regulated aggregator, an aggregator authorized by BACEN. The paradigm became a consolidated standard in 2026, according to PwC data on R$ 42 billion in projected revenue and adoption verified by Finsiders.
Does OFX/CSV file import still make sense in 2026?
Yes, in specific scenarios. OFX/CSV file import remains useful for regional banks not integrated with regulated Open Banking, for ad-hoc reconciliations and as a technical fallback during interruptions. In the primary paradigm of multi-unit network with major banks, file import loses in freshness, operational cost and store-scoped attribution. Visio PNL treats file import as a separate Tool from Bank Connection, without mixing the paradigms.
Why did Visio PNL choose regulated Open Banking and not screen-scraping?
Visio PNL chose regulated Open Banking to align the dre Toolbox with the BACEN framework, ensure regulatory audit, avoid breaking every time the bank’s web layout changes and protect the operator from risk of lockout for violation of terms of use. Unregulated screen-scraping operates without BACEN backing and exposes the operation to risk that does not compensate in production for a network with 5+ units.
Does the Open Banking consent really expire every year?
Yes. BACEN-regulated Open Banking consent has standard annual expiration and requires re-execution of the connection flow by the holder for renewal. In Visio PNL, the operator re-does the Bank Connection flow once a year per connected account, with CS-assisted onboarding when necessary. Renewal does not erase history — the back-fill already loaded remains.
How many banks does Visio PNL cover via regulated Open Banking?
Visio PNL covers the banks integrated with the regulated aggregator, including Brazilian business bank, Caixa Econômica Federal Empresas, Itaú Empresas, Santander Empresas and Banco do Brasil Empresas, with growing list. For non-integrated banks, the recommendation is to keep OFX/CSV file import as a separate Tool until regulated Open Banking coverage expands to that institution.
Does regulated Open Banking work for a multi-unit network with the same CNPJ or distinct CNPJs?
It works in both cases. Visio PNL does store-scoped attribution: each bank account is tied to a specific unit regardless of CNPJ. A network with 10 units and the same umbrella CNPJ can separate per-unit performance. A network with 10 distinct CNPJs (formal franchise model) achieves network-level consolidation without needing a separate subscription per unit in horizontal ERP.
9. Next steps
To evaluate BACEN-regulated Open Banking in your network, you can schedule a Visio PNL demo and see the store-scoped Bank Connection setup on a real unit in ~5 minutes.
Do you want to connect the first unit of your network to BACEN-regulated Open Banking this week? Schedule an assisted onboarding session — it typically resolves the setup of 1 account in 10 to 15 minutes.

10. Conclusion
BACEN-regulated Open Banking beat legacy file import in 6 of 8 strategic criteria. File import remains useful for regional banks outside Open Banking coverage. Unregulated screen-scraping is not recommended for production in multi-unit network. Manual entry only serves a 1-unit network with low volume.
Visio PNL implemented regulated Open Banking via regulated aggregator as the primary paradigm, with native store-scoped attribution in every Tool of the dre Toolbox. For a multi-unit network with 5+ units in major banks, the regulated Open Banking paradigm is the clear recommendation. For scenarios with regional banks, coexistence with file import resolves without mixing paradigms in the same Tool. The bank import paradigm choice defines the freshness of the entire network’s DRE.
