Finance shared services model: a step-by-step checklist
- A finance shared services model centralizes transactional finance work into one internal unit that serves many business units.
- Setup follows a clear sequence: assess, scope, design, standardize, choose technology, set SLAs, transition, and measure.
- Shared services often becomes the launchpad for wider outsourcing or a global business services (GBS) structure.
A finance shared services model pulls repeatable finance tasks out of separate units and runs them as one service. Instead of every division keeping its own accounts payable team, the work moves to a single center. That center handles invoices, payments, ledgers, and payroll for the whole group.
The goal is simple. You want fewer duplicated roles, cleaner data, and one standard way of working. Done well, the center runs like an internal provider with its own targets and pricing. This checklist walks through each step to build one.
What is a finance shared services model?
A finance shared services center consolidates transactional finance work into one team. It usually starts with accounts payable, accounts receivable, general ledger, and payroll. The center serves several business units at once, so the group gains scale and consistency.
The unit sits inside the company, yet it behaves like an outsourcer. It uses service level agreements, cost recovery, and customer-style governance. Because the model standardizes work, it also prepares finance for automation and analytics.
Step-by-step checklist to set up the model
1. Assess your current finance processes
Start with a clear baseline. Map how each unit handles invoices, payments, and reporting today. Record volumes, cycle times, error rates, and headcount. This shows you where duplication and manual work hide. As a result, you can target the biggest wins first.
2. Define scope and build a service catalog
Decide which processes move to the center. Transactional, high-volume work fits best, for example accounts payable and payroll. Keep judgment-heavy tasks like tax strategy with the business. Then write a service catalog. It lists each service, who owns it, and what “good” looks like.
3. Design the operating model and location strategy
Now choose how the center will run. Decide on a single hub or a few regional sites. Weigh time zones, language, talent supply, and cost. Labor arbitrage matters, but so does quality and continuity. Because location drives risk, pick a place with a deep finance talent pool.
4. Standardize and document processes
Standardization is the heart of the model. Agree on one way to process an invoice across every unit. Document each step in a clear playbook. Remove exceptions where you can, and log the ones that remain. Clean, uniform processes make later automation far easier.
5. Choose the technology stack
Match tools to your standardized processes, not the other way around. A shared ERP or ledger keeps data consistent. Add workflow tools, and consider robotic process automation for repetitive tasks. Deloitte notes that leading centers now treat digital capability as a core priority. In its 2025 survey, Deloitte found “Over 50% of the responding GBS organizations consider next gen capability development and customer experience as top priorities”.
6. Set SLAs and governance
Turn the service catalog into measurable promises. Set service level agreements for cycle time, accuracy, and query response. Agree who reports to whom and how disputes get resolved. Governance keeps the center accountable to the units it serves. In short, clear rules prevent finger-pointing later.
7. Plan and run the transition
Move work in waves, not all at once. Start with one simple, high-volume process to prove the model. Run the old and new setups in parallel for a short window. Train staff, transfer knowledge, and keep a close eye on service quality. Then scale to the next process.
8. Measure performance and improve
Track a small set of clear metrics from day one. Watch cost per transaction, cycle time, error rates, and satisfaction scores. Review them against your SLAs each month. Because the model should keep improving, feed the results back into your playbooks.
Shared services versus other models
Many leaders compare three finance delivery options before they commit. The table below shows how they differ on control, cost, and reach.
| Factor | Decentralized | Shared services | Outsourced |
|---|---|---|---|
| Ownership | Each unit runs its own finance | One internal center serves all units | External provider runs the work |
| Standardization | Low, many local variations | High, one common process | High, set by the provider |
| Cost profile | Higher, from duplication | Lower, from scale | Variable, often lowest labor cost |
| Control | Full, but fragmented | Strong, kept in-house | Shared through contracts and SLAs |
How this links to outsourcing and GBS
A shared services center is often a first step, not a final one. Once processes are standard and measured, they become easy to hand to an outsourcing provider. Many groups blend both, keeping some finance work in-house and sending the rest offshore.
Over time, some firms fold finance, HR, and IT into one global business services structure. Deloitte describes this as a shift from back-office to center office, which it calls the “next evolution of global business services (GBS) and shared services”. You can compare the three models in this breakdown of GBS, shared services, and outsourcing. For a deeper setup guide, review these shared services best practices.
Frequently asked questions
Which finance processes should move first?
Start with high-volume, rules-based work. Accounts payable, accounts receivable, general ledger, and payroll are common first movers. They are easy to standardize and quick to show savings.
How long does setup take?
Most groups plan for a phased rollout across several months. A single process pilot can go live in a few months. Full transition of all units often takes a year or more.
Is shared services the same as outsourcing?
No. Shared services keeps the work inside your company under your control. Outsourcing hands it to a third party. Many firms use both, and shared services often comes first.
How do we measure success?
Set SLAs and track a few clear metrics. Cost per transaction, cycle time, accuracy, and satisfaction scores work well. Review them monthly and adjust your playbooks.
Key takeaways
- Build the model in order: assess, scope, design, standardize, choose tools, set SLAs, transition, then measure.
- Move transactional finance first, and standardize each process before you automate it.
- Clear SLAs and governance keep the center accountable to the business units it serves.
- Shared services often becomes the bridge to wider outsourcing or a full GBS model.
