What Made Spendflo Migrate to Truto from a Leading Unified API

Challenge

Explosive integration demand — Enterprise customers rely on many ERP, HRMS, and procurement tools. Each new logo expects Spendflo to plug into its existing stack. Internal estimates showed a need for 50 integrations in 12 months—roughly one every week.
Build-versus-buy dilemma — Building "hundreds or thousands" of connectors in-house would tie up core engineering resources and slow the roadmap. An initial split approach—using Truto for non-accounting data and a leading unified API (Merge) for accounting—created cost spikes and inconsistent support.
Time-sensitive sales cycles — Deals hinged on niche integrations such as Oracle NetSuite and Coupa. Missing a required connector risked stalling enterprise pilots.

Spendflo adopted Truto as its sole integration layer and gained four decisive advantages:

Unified endpoints for ERP, HRMS, SSO, and usage tracking — Everything runs under one contract and SDK instead of a patchwork of bespoke builds.
On-demand connector development — New connectors—like the Coupa integration—can go live in just a few days, giving sales teams the confidence to engage large procurement prospects.
Flexible commercial model — Pricing scales predictably with each integration instead of each customer, eliminating the exponential cost curve experienced with the previous vendor.
Hands-on technical support — Truto's engineers rapidly add new scopes and endpoints, so Spendflo's product experiments never stall.

Pricing scalability — With Merge, each new customer drove costs up exponentially. Truto offers a predictable, linear pricing model.
Roadmap alignment — Merge's rigid prioritization delayed delivery of new scopes and endpoints. Truto operates on a collaborative, "customer-first" roadmap.
Hands-on support — Truto provides a direct Slack channel with engineering ownership for rapid turnaround.

Scope: 10 critical accounting integrations (including NetSuite, QuickBooks, Xero).
Cadence: 1 integration per week over 10 weeks.
Approach: Truto replicated Merge's data model field-for-field, so Spendflo's application logic remained untouched.
Outcome: Zero code changes on the Spendflo side, no downtime for existing customers, and a single vendor managing the full connector catalogue.

Month 0 – Backlog triage — Truto and Spendflo mapped the first fifty requested integrations, prioritising by live deal impact.
Months 1-3 – Merge migration — Ten accounting connectors moved from Merge to Truto at a pace of one per week. Truto replicated the original data model field-for-field, so Spendflo's codebase stayed unchanged and customers saw zero downtime.
Month 2 – Oracle NetSuite cut-over — Data quality matched the previous provider while Truto added new endpoints requested by Spendflo's product team.
Month 4 – Coupa launch — A net-new Coupa connector went live in days, enabling an "intake-to-procure" workflow that helped close several enterprise accounts.

Dedicated two-engineer integrations pod at Spendflo will focus on expanding Truto coverage rather than reinventing connectors.
Thousands of integrations — Spendflo will continue to build and launch with Truto as it gets closer to its integration targets.
Deeper usage analytics through Truto endpoints will feed Spendflo's renewal and savings insights.

Speed wins enterprise deals. A unified API partner can turn integration requests from blockers into closing assets.
Seamless migrations protect momentum. Mirroring the outgoing provider's data model avoids costly code rewrites.
Service quality matters as much as code. Responsive support accelerates experimentation and reduces hidden costs.
Strategic focus beats resource drain. Outsourcing non-core plumbing lets product teams double down on differentiated features.

Integrations are key for us to sell in different markets. Truto is how we move customers to the next level. — Spendflo Leadership
