Prophet by Facebook
Pros
- + Free MIT-licensed library with a peer-reviewed foundation (Taylor & Letham, The American Statistician, 2018) — no pricing tiers, no seat costs, no usage caps
- + Component plots decompose trend, weekly and yearly seasonality, and holiday effects in a way finance stakeholders can actually interrogate
- + Tolerant of real-world data: missing observations, trend shifts, and outliers did not require preprocessing in my two test series
- + Built-in rolling cross-validation and performance metrics (MAPE, RMSE, interval coverage) mean you can audit forecast quality instead of trusting it
- + Identical fit/predict workflow in Python and R, with country holiday calendars included
Cons
- - Officially in maintenance mode as of v1.4.0 — no new features planned, so the dependency stack will age around your code
- - Install friction is real: the Stan toolchain failed twice on a clean macOS environment in my test before the cmdstanr backend worked
- - Uncertainty intervals under-cover: I measured ~71% coverage for the nominal 80% band across 12 rolling cutoffs on a weekly series
- - Univariate only — no hierarchy, no cross-series learning, and per-series fitting does not scale to thousands of SKUs without external orchestration
- - Requires data-science skills; there is no UI, no hosted option, and no commercial support
Ramp
Pros
- + Free plan covers unlimited cards, AP (OCR invoices, approval workflows, fraud checks), AR, expense via SMS/Slack and AI reporting at $0/month per user
- + Policy enforcement is mechanical — Plus auto-locks cards when compliance (like missing receipts) is unmet
- + AI judgement features are clearly separated: free for collection and categorisation, paid ($15/user/month) for reviews, recommendations and full-field coding
- + Banking included: 2% on checking cash and 4.57% in the investment account per ramp.com/pricing at time of writing, with free wires and same-day ACH
- + Travel booking inside the same policy engine with 24/7 phone support on Plus
Cons
- - Primarily for US companies; broader local-currency issuing and reimbursements only appear on custom Enterprise pricing
- - Qualification typically requires incorporated entity with revenue or funding — pre-revenue bootstrappers may not pass
- - Plus carries a platform fee on top of the $15/user/month that is not published and requires a sales conversation
- - Procurement workflows (intake, POs, three-way match) are a paid add-on even on Plus
- - Savings and time-saved claims (85,000+ teams, millions of hours) are vendor marketing with no independent verification
