AI Travel Consulting. 85% Zero-Touch. Client Split. One Agent.
Three-way split: client, cost center, tax. Every trip different.
The AI Agent classifies client allocation, cost distribution, and tax treatment per travel day. The rule engine calculates splits deterministically. Humans stay where client agreements or tax law requires it.

What the Agent classifies
Three splits, one agent
Tax, client, internal - each trip creates three cost perspectives simultaneously. You know the complexity. Here's how the AI Agent solves it:
Three-way split per transaction
Every consulting expense has three cost perspectives simultaneously. The AI Agent classifies each expense into tax treatment, client allocation, and internal cost assignment. The rule engine then calculates all three splits deterministically - deductible vs. non-deductible, billable vs. internal, cost centre vs. project vs. overhead. One transaction, three perspectives, zero manual intervention.
Multi-client weeks auto-split
A consultant visits Client A on Monday, Client B on Wednesday. The AI Agent reads calendar and project management data to classify each day to its client. The rule engine splits hotel costs proportionally, adjusts per diems mid-week, and allocates every euro to the correct client project - automatically, documented, audit-ready.
Policy conflict auto-resolved
Internal travel policies and client-specific budgets often conflict. The AI Agent identifies both applicable policies per transaction. The rule engine enforces the stricter rule and documents which policy took precedence and why - no escalation needed for standard conflicts.
Entertainment costs by jurisdiction
Germany: 70% deductible. Austria: 50%. Switzerland: fully deductible if documented. (UK: entertainment of clients is generally not deductible under HMRC rules.) The AI Agent classifies receipt type, country, and attendee count. The rule engine applies the correct deduction rate per jurisdiction - deterministically, for every receipt, without exception.
Client billing auto-documented
200 consultants, 4 client trips per month each, 800 cases. The AI Agent checks 100% against client contract terms and generates audit-ready expense documentation per client. Systematic billing errors eliminated at the source - not discovered during quarterly reconciliation.
One consulting week. 20 to 60 micro-decisions.
A consultant visits three clients in one week with business dinners and changing hotels. The Decision Layer decomposes this week into individual decision steps:
| Step | Decision | Decider | Rationale |
|---|---|---|---|
| 1 | Map trip to client project | Rule engine | Calendar or CRM integration |
| 2 | Determine per diem | Rule engine | Country-specific rate per jurisdiction |
| 3 | Split hotel cost: billable vs. internal | Rule engine | Client contract terms determine split |
| 4 | Check client-specific travel policy | Rule engine | Client economy-only vs. internal first-class |
| 5 | Apply stricter policy | Rule engine | Whichever is more restrictive applies |
| 6 | Tax treatment classification | Rule engine | Deductible, partially deductible, entertainment |
| 7 | Multi-client day split | AI + Rule engine | AI determines time allocation, rules apply cost split |
| 8 | Generate client invoice backup | Automatic | Audit-ready expense documentation per client |
| 9 | Classify entertainment expenses | AI + Rule engine | AI identifies receipt type, rule engine applies jurisdiction-specific deduction rates |
| 10 | Generate audit file | Automatic | Sealed decision record per consulting week |
Simulation
Calculated for consulting volumes
We configured the Travel Decision Layer with realistic consulting parameters and ran the numbers. The results show what changes at enterprise volumes.
Simulation parameters
| Consultants | 100 to 500+ (with client-specific policy rules) |
| Client contracts | 10 to 50+ parallel (each with own travel policies) |
| Cases/year | 50,000 to 250,000+ |
| Jurisdictions | Multi-jurisdiction (DE, AT, CH, UK, further EU) |
| System integration | CRM/time tracking → Decision Layer → ERP/Payroll |
| Entertainment share | 15 - 25% of all cases contain entertainment receipts |
Before / After
| Dimension | Manual | Decision Layer |
|---|---|---|
| Processing cost | from EUR 53 (GBTA)* | < EUR 9 |
| Error rate | 19% (GBTA) | < 0.3% |
| Lead time | 5 - 12 business days | Minutes |
| Zero-touch rate | 0% | 85% |
| Audit-readiness | Manually reconstructed | Automatically generated |
| Split accuracy | Manual estimate | Deterministically calculated |
| Client billing | Manually assigned | Automatically documented |
* GBTA Foundation 2024: USD 58 per transaction (approx. EUR 53). Consulting cases with three-way split and multi-client logic are typically higher. Simulation results: Gosign model calculation.
In the simulation, the Decision Layer achieves a zero-touch rate of 85% - for standard cases with clear client allocation. The remaining 15% involve multi-client days and edge cases requiring human judgement. For all cases, a complete, audit-proof decision record is available.
Architecture and implementation
The Travel Decision Layer runs entirely on your infrastructure: your data centre, your network, your sovereignty. No SaaS dependency, no data leakage. For consulting configurations, this means: multi-client capability with separate policy rulesets, integration with project management and time tracking systems, and automated three-way split. Typical pilot projects start within 3 months with one client pool.

Travel Decision Layer in Other Industries
Each industry has its own tariffs, cost structures, and complexity drivers. The Decision Layer is the same. The configuration is industry-specific.
Frequently Asked Questions
Can the Decision Layer handle client-specific travel policies?
Yes. Each client project can have its own policy ruleset. The Decision Layer compares internal policy and client policy and applies the stricter rule, documenting which policy took precedence.
How does multi-client week allocation work?
The Decision Layer splits costs by day and by client based on calendar or project management data. Hotel stays spanning multiple client days are allocated proportionally. Every split is documented in the audit trail.
Does it integrate with project management and time tracking tools?
The Decision Layer is configurable to read project assignments from standard tools. The integration maps travel days to projects without requiring consultants to duplicate data entry.
How are entertainment expenses classified?
Entertainment expenses follow jurisdiction-specific rules. The Decision Layer classifies each expense by type and applies the correct tax treatment. Mixed business-entertainment events are split based on configurable rules.
How does a project start in practice?
