Build vs Buy: Should Your Factoring Company Build Its Own Automation?
By Zolvo Team · 5 min read
Sooner or later every growing lender asks the question: should we just build this ourselves? The manual work is obvious, the logic seems tractable, and there is usually an engineer or two on staff or a vendor who says it is straightforward. Building your own servicing automation, cash application, verification, collections, is a real option. It is also one that looks far cheaper at the start than it turns out to be.
This article is a straight look at the build-versus-buy decision for factoring and lending automation: what building actually costs, when it makes sense, and how to decide.
Why building looks attractive
Building appeals for good reasons. You control the roadmap. It fits your exact SOPs. There is no per-seat or per-transaction fee. And the first version, a script that matches the easy payments, often comes together quickly and convincingly. That early win is exactly what makes the decision dangerous, because the easy 70 percent is not where the cost lives.
Where the cost actually is
The cost of servicing automation is in the long tail: the exceptions, the formats, and the maintenance. Short pays and disputes. Every bank's slightly different file. Remittances that arrive as messy PDFs. A debtor portal that changes overnight. Fraud patterns that evolve. Each of these is a small project, and together they never end, because the world your software reads keeps changing. A team that builds the matching engine signs up to maintain it forever, with engineers who could have been building your actual lending product.
The demo is the easy 70 percent. The business is the other 30 percent: the exceptions, the formats, and the maintenance that never stops. Build-versus-buy is really a question of who maintains the long tail.
When building makes sense
Building can be the right call when automation is a genuine source of competitive advantage you intend to invest in for years, when you have a dedicated product and engineering team that will own it indefinitely, and when your processes are so unusual that no external tool fits. For most lenders, none of those three fully holds, and the honest answer is that servicing automation is critical infrastructure but not their differentiator.
How to decide
- Estimate the fully loaded cost of the engineers who would build and then maintain it, every year, not just the first.
- Be honest about the long tail: who handles the new bank format or the changed portal in month nine?
- Weigh time to value: a bought solution that works in weeks versus a built one that is always a quarter away.
- Remember the two decisions are separable: you can buy the automation layer and keep full control of your system of record.
