How to empower engineers to build with AI on financial data

AI is reshaping how software products work with financial systems. But while the potential is clear, many engineering teams face a consistent challenge: building AI features shouldn't require becoming an expert in dozens of accounting APIs, payment processors, and regional compliance frameworks.

The question isn't whether engineers should build AI features, it's how to remove the infrastructure barriers that slow them down.

This article explores how to empower engineering teams to build AI-powered financial features without multiplying integration complexity, and why the right abstraction layer makes AI development accessible rather than overwhelming.

The infrastructure gap in AI development

When engineers start building AI features for financial workflows, they quickly encounter a gap between what AI models can do and what systems they can reliably interact with.

Consider a simple use case: an AI assistant that helps users reconcile daily sales from their POS system with their accounting records.

The AI logic might be straightforward: compare two datasets, identify discrepancies, suggest corrections. But the infrastructure work is extensive:

• Authenticate with multiple POS systems (Lightspeed, Square, Zettle, L'Addition)
• Handle different data formats and field mappings for each
• Normalize sales data across Continental and Anglo-Saxon accounting models
• Connect to accounting platforms (Pennylane, Sage, QuickBooks, Xero)
• Map transactions to the correct chart of accounts for each system
• Handle edge cases: partial refunds, multi-currency transactions, tax variations
• Maintain sync reliability and handle API rate limits
• Ensure compliance with regional financial regulations

This infrastructure gap is where many AI projects stall. Engineers either spend months building custom connectors, or they limit AI features to a narrow set of supported systems, leaving customer demands unmet.

Why financial AI needs specialized infrastructure

Generic integration platforms help with some of this, but financial data has unique characteristics that make domain-specific infrastructure essential:

Accounting models vary fundamentally

Continental European accounting follows strict journal-based structures with regulated charts of accounts. Anglo-Saxon systems are more flexible and invoice-centric. An AI feature working across both needs an abstraction layer that understands these differences, not just raw API access.

Without this, your engineers either:

• Build system-specific logic for every connector (doesn't scale)
• Force users to configure complex field mappings (poor UX)
• Limit AI features to one accounting model (reduces market reach)

Data accuracy is non-negotiable

AI models can hallucinate. Financial data cannot. When an AI assistant posts a journal entry or marks an invoice as paid, the data must be correct and auditable.

This requires infrastructure that:

• Validates data before writing to accounting systems
• Maintains audit trails of all AI actions
• Provides rollback capabilities when needed
• Enforces business rules (account types, mandatory fields, tax calculations)

Real-time context matters

Effective financial AI needs current data. Stale reports or delayed sync make AI suggestions unreliable. Engineers need infrastructure that provides real-time access without building and maintaining webhook handlers, polling logic, and sync conflict resolution for every system.

Compliance can't be an afterthought

European financial regulations (GDPR, PSD2, regional tax requirements) aren't optional extras. Infrastructure must handle data residency, consent management, and regulatory reporting at the platform level, not as custom code in every AI feature.

What engineers need to build financial AI effectively

Based on conversations with engineering teams building AI-powered financial products, here's what makes the difference between productive AI development and infrastructure quicksand:

1. A unified data model that AI can reason about

AI models work best with consistent, well-structured data. When every accounting system has different field names, data types, and business logic, your prompts and model logic become system-specific.

A unified data model means:

• One schema for "invoice" across all platforms
• Consistent field names and data types
• Normalized enums (invoice status, payment methods, account types)
• Predictable relationships between entities

This lets engineers write AI logic once and have it work across systems.

2. Agent-native APIs and tools

Traditional REST APIs require engineers to write explicit integration code. Agent-native infrastructure provides tools that AI models can call directly:

MCP (Model Context Protocol) tools - standardized functions AI agents can invoke:

get_invoices(status='unpaid', customer_id='123')
create_journal_entry(account='600000', amount=1500, description='...')
reconcile_transaction(payment_id='abc', invoice_id='xyz')


Natural language query capabilities - AI can request data semantically:

"Get all unpaid invoices over €1000 from the last 30 days"
"Find journal entries posted to advertising accounts in Q4"


Contextual reasoning support - the infrastructure understands financial concepts:

• Account hierarchies and relationships
• Tax calculation rules by region
• Currency conversion and multi-currency handling
• Fiscal period constraints

3. Built-in observability for AI actions

When AI acts autonomously, engineers need visibility into what's happening:

• Action logs - complete audit trail of every AI decision and API call
• Data lineage - trace where data came from and how it was transformed
• Error transparency - understand why an AI action failed with actionable context
• Performance metrics - track AI feature usage, success rates, and bottlenecks

This observability isn't just for debugging—it's essential for building trust with users who need to understand what AI is doing with their financial data.

4. Gradual autonomy controls

Not every AI feature should be fully autonomous from day one. Engineers need infrastructure that supports a spectrum:

• Read-only mode - AI analyzes and suggests, humans execute
• Draft mode - AI prepares transactions, humans approve before posting
• Supervised autonomy - AI acts within guardrails, escalates edge cases
• Full autonomy - AI executes routine operations, logs for audit

The infrastructure should make it easy to move features along this spectrum based on user trust and regulatory requirements.

5. Fast iteration cycles

AI features improve through iteration. Engineers need infrastructure that supports:

• Quick connector additions - new system support in days, not months
• Safe experimentation - sandbox environments that mirror production
• A/B testing support - try different AI approaches with real users
• Rapid rollback - undo changes quickly when something goes wrong

Slow integration cycles kill AI innovation. Fast cycles enable continuous improvement.

How Chift enables engineers to build financial AI

Chift is designed specifically to remove infrastructure barriers for engineers building AI features on financial data.

Unified model built for AI reasoning

Chift's data model is designed for both human developers and AI agents:

• Consistent schemas across accounting, POS, payments, and invoicing systems
• Semantic field names that AI models understand naturally
• Clear relationships between entities (invoices ↔ payments ↔ journal entries)
• Normalized enums and controlled vocabularies

This means your AI logic is portable. Write it once, it works across all supported systems.

MCP-native tool suite

Chift provides Model Context Protocol tools that AI agents can call directly:

Data access tools:

• list_invoices - query invoices with semantic filters
• get_pos_sales - retrieve sales data from any connected POS
• get_account_balance - check balances across accounting systems
• search_transactions - find transactions by natural language criteria

Action tools:

• create_invoice - generate invoices in any connected system
• post_journal_entry - create accounting entries with automatic format translation
• reconcile_payment - match payments to invoices intelligently
• create_credit_note - handle refunds and corrections

Reasoning tools:

• validate_transaction - check if a transaction is valid before posting
• suggest_accounts - recommend chart of accounts based on description
• calculate_tax - compute tax based on region and transaction type

These tools abstract away system-specific complexity, letting engineers focus on AI logic.

Built-in compliance and validation

When AI calls a Chift tool, the infrastructure enforces:

• Data validation against target system rules
• Required field checking
• Account type compatibility
• Tax calculation correctness
• Regional compliance requirements

This means engineers don't need to become experts in each system's business rules. The infrastructure handles it.

Observability for AI actions

Every AI action through Chift creates:

• Audit log entry with full context
• Data lineage tracking
• Performance metrics
• Error details when things fail

Engineers can trace exactly what AI did, why it made decisions, and how to improve results.

Gradual path to production

Chift supports building AI features incrementally:

1. Start with read-only - AI analyzes data, makes suggestions
2. Add draft mode - AI prepares transactions for human approval
3. Enable supervised autonomy - AI acts within rules, escalates exceptions
4. Scale to full autonomy - AI handles routine operations independently

The same infrastructure and tools work at every stage. No rewrite needed as you increase autonomy.

Common pitfalls and how to avoid them

Pitfall 1: Building too much infrastructure before validating value

Problem: Teams spend months building integration infrastructure before testing if AI actually helps users.

Solution: Use a platform like Chift to skip infrastructure work and get to AI logic faster. Validate value first, scale second.

Pitfall 2: Treating AI as a "nice-to-have" feature

Problem: AI features get deprioritized when engineering resources are tight.

Solution: Frame AI as core product capability, not a bonus. Users increasingly expect AI assistance in financial workflows.

Pitfall 3: Ignoring observability until something breaks

Problem: AI acts autonomously, then makes a mistake. Without proper logging, debugging is impossible.

Solution: Build observability from day one. Every AI action should be traceable and explainable.

Pitfall 4: Assuming AI can work with incomplete or low-quality data

Problem: AI features fail because underlying data isn't clean or complete.

Solution: Use infrastructure that validates and normalizes data before AI sees it. Garbage in, garbage out applies to AI too.

Pitfall 5: Not planning for gradual autonomy

Problem: Launching fully autonomous AI without building user trust leads to adoption resistance.

Solution: Start with AI suggestions, add approval workflows, gradually increase autonomy as users gain confidence.

The future of financial engineering is AI-augmented

The shift from manual integrations to AI-powered financial operations is accelerating. Engineering teams that embrace this shift early gain competitive advantages:

• Faster feature development - AI logic instead of integration plumbing
• Better user experiences - intelligent automation instead of manual data entry
• Scalable architecture - one AI feature works across many systems
• Continuous improvement - AI learns from data and user feedback

But realizing these benefits requires the right infrastructure foundation. Engineers shouldn't need to become experts in accounting APIs, regional tax codes, and data normalization to build AI features.

Specialized infrastructure platforms like Chift abstract this complexity, letting engineering teams focus on what makes their product unique: the AI-powered experiences that solve real user problems.
