If per diem must be computed from travel dates and locations, Certify Expense provides a policy engine built for that calculation approach.

Common Mistakes to Avoid
Common failures come from underestimating per diem policy setup complexity, misaligning approvals with actual exception paths, or expecting reporting that matches spreadsheet-style needs.
Choosing a tool without validating how complex per diem rule setups are configured
Certify Expense can handle automated per diem policy calculations but complex per diem rule setups require careful admin configuration. Rydoo and Expensify also require careful configuration of per diem rules and categories for edge cases.
Assuming per diem reporting will be simple summaries without configuration
Certify Expense can feel heavy for teams that want simple summary reporting depth, and Rydoo’s reporting depth depends on configuration and available data fields. Zoho Expense and Zoho Expense for Per Diem Policies deliver strong finance review reporting but can be less tailored for policy analytics.
Building per diem processes that ignore mobile capture and OCR reality
Expensify’s smart scan and receipt OCR can reduce manual entry, but teams that skip mobile capture workflow adoption increase cleanup work in expense submissions. WEX Fleet Cards and Expense can feel rigid for non-card users because its workflow navigation can be less aligned to non-card reimbursement behaviors.
Mismatch between per diem approvals and the way teams actually make decisions
Certify Expense and Zoho Expense both rely on approval workflow automation, but rigid edge-case handling can occur if approval routing does not match real exception paths. Rydoo’s approval routing needs careful configuration to match team decision paths for per diem compliance.
How We Selected and Ranked These Tools
we evaluated each per diem software tool on three sub-dimensions with explicit weights of features at 0.4, ease of use at 0.3, and value at 0.3. the overall rating is the weighted average computed as overall = 0.40 × features + 0.30 × ease of use + 0.30 × value. Certify Expense separated itself by combining a per diem policy engine for allowances calculated from travel dates and locations with approval workflows that reduce manual allowance work, which scored strongly in the features dimension. Lower-ranked tools tended to trade away policy flexibility, reporting depth, or per diem rule coverage for other strengths like receipt OCR or accounting ecosystem fit.
