How to build the business case for bookkeeping automation at your trust company

Written by Landytech | May 26, 2026 4:40:06 PM

Most trust company leaders already know that manual bookkeeping is a problem. The question is rarely whether to automate. It is how to justify the investment internally, and how to frame the case in terms that resonate with those making the final decision.

This blog is designed to help you do that. It walks through the costs that manual processes impose, the returns that automation delivers, and the broader strategic arguments that make this more than an efficiency exercise.

Start with what manual bookkeeping is actually costing you

The direct costs of manual bookkeeping are easier to quantify than most teams expect. The starting point is staff time.

Trust bookkeeping is labour-intensive by nature. Transaction data arrives from multiple custodians in different formats, often requiring manual reconciliation, reformatting, and re-entry into your accounting system. For a team managing a large book of trusts, this can consume a significant portion of each administrator's week. Across a quarter, the cumulative time cost is substantial.

There are also indirect costs worth capturing. Error rates in manual data entry lead to reconciliation failures, rework, and in some cases write-offs. Landytech clients have reported recovering around 4% of revenues that were previously lost to write-offs after automating their bookkeeping processes. That figure will vary by firm, but the principle holds: errors are not just an operational inconvenience, they have a direct line to the bottom line.

A third cost is opportunity cost. Time spent on data entry is time not spent on client service, business development, or higher-value advisory work. For a trust company where administrator capacity is one of the core constraints on growth, this is often the most significant cost of all.

When building your business case, quantify all three:

  • Direct time cost: Estimate the hours per trust per quarter spent on manual bookkeeping tasks, multiply by the fully loaded cost of the staff involved, and project across your full book.
  • Error and write-off cost: Review recent reconciliation failures and write-offs for patterns that trace back to manual data handling.
  • Opportunity cost: Assess what your team could be doing with recovered time, and what that is worth in terms of client retention or new business capacity.
  • Current state cost: Annual cost of manual bookkeeping in staff time, errors, and write-offs
  • Future state cost: Platform cost net of efficiency gains
  • Net annual saving: The difference, expressed in both monetary and time terms
  • Payback period: How quickly the investment recoups itself
  • Strategic case: What growth becomes possible that is not possible today

Frame the returns clearly

The returns from bookkeeping automation at trust companies fall into three categories: cost reduction, revenue protection, and growth enablement.

Cost reduction is the most straightforward to model. Automating transaction postings eliminates the majority of manual data entry. Affinity Trust, a Jersey-based trust and corporate services provider, reduced manual transaction posting by 70% after implementing Sesame Data, with bookkeepers shifting from intensive quarter-end reconciliation to daily exception handling — read the Affinity Trust case study. Translating that percentage into your firm's context requires applying it to your current time estimates and staff costs.

Revenue protection comes from two sources. First, fewer errors mean fewer write-offs and fewer corrections. Second, automation creates the capacity to meet regulatory and client reporting deadlines consistently, reducing the reputational and commercial risk that comes from missed deadlines. Trust companies that have adopted Sesame Data report significantly greater confidence in meeting time-sensitive regulatory requirements.

Growth enablement is the strategic argument, and often the most compelling one for senior leadership. A trust company constrained by bookkeeping capacity cannot grow its book without adding headcount proportionally. Automation breaks that dependency. Landytech clients have scaled their business without additional headcount, which changes the economics of growth materially. Ocorian adopted Sesame Data to automate bookkeeping and portfolio monitoring, enabling them to scale their private client services without proportional cost increases — read more about their approach. In a market where industry consolidation is accelerating and competition for mandates is intensifying, the ability to grow without a linear increase in costs is a meaningful competitive advantage.

Address the costs of investment

A credible business case acknowledges the costs on both sides. The relevant considerations for most trust companies are implementation time, integration requirements, and the internal resource needed during transition.

On implementation, the key question is how quickly the platform connects to your existing custodian relationships and accounting systems. Sesame Data has active connections to over 500 custodians and is designed to integrate with existing ERP and bookkeeping systems, which materially reduces the complexity and duration of implementation. Affinity Trust highlighted Landytech's existing coverage of major investment managers as a decisive factor in their selection.

On transition, the more relevant risk to model is not the short-term disruption of implementation, but the ongoing cost of not acting. For most trust companies operating at scale, the cost of maintaining manual processes for another two to three years outweighs the implementation cost many times over.

For Jersey-based firms, it is also worth noting that the Jersey Better Business Grant can offset a portion of implementation costs, improving the payback period for the investment.

Build the one-page summary your decision-makers need

When presenting the case internally, the goal is to reduce the decision to its essential logic. A one-page summary should include:

The broader context

There is a version of this conversation that treats bookkeeping automation as a cost-cutting exercise, and a version that treats it as a strategic investment. The firms making the most of it are doing the latter.

The trust sector is consolidating. Larger players are investing in technology that allows them to service more clients at lower cost per trust. Independent and mid-sized trust companies that delay investment in automation risk a widening operational gap relative to better-capitalised competitors, at exactly the moment when the competitive environment is becoming more demanding.

The firms investing in automation now are not doing so to cut costs in isolation. They are removing the operational ceiling on growth, at a moment when the competitive environment leaves little room for firms that cannot scale efficiently.

Landytech's Sesame Data platform is designed for trust companies seeking to automate bookkeeping, streamline investment monitoring, and scale their operations without proportional increases in headcount.
