For field service businesses, operational efficiency and financial accuracy go hand in hand. Engineers complete jobs, consume parts and record time, but if these activities are not seamlessly connected to billing, revenue leakage becomes inevitable. Missed charges, delayed invoices and inaccurate stock records can erode margins and damage customer trust.
Microsoft Dynamics 365 Business Central, combined with Dynamics 365 Field Service, provides a unified approach to managing service operations and finance. By integrating work orders, inventory and invoicing, businesses can eliminate gaps that lead to lost revenue. This blog explores best-practice flows for service organisations that rely on ERP for stock, pricing and billing.
Why revenue leakage happens in field service
Revenue leakage often stems from disconnected systems and manual processes. Common issues include:
-
Unbilled parts and labour: Engineers use materials or spend extra time on-site, but these costs never make it to the invoice.
-
Delayed invoicing: Paper-based job sheets or siloed apps slow down billing cycles, creating cash flow gaps.
-
Stock inaccuracies: Parts consumed in the field are not recorded promptly, leading to overstocking or shortages.
-
Pricing errors: Without real-time access to ERP pricing, engineers may quote incorrectly, impacting margins.
According to Forrester, businesses that integrate service and finance systems can reduce revenue leakage by up to 20% and accelerate billing cycles by 30%. For SMEs and mid-market firms, this improvement can make a significant difference to profitability.
Best-practice integration flows
To stop revenue leakage, service operations must connect seamlessly with ERP processes. Here’s how Business Central and Dynamics 365 Field Service deliver this:
1. Work order creation and synchronisation
When a service call is logged in Dynamics 365 Field Service, a work order is created with details of the job, required parts and estimated labour. Integration ensures this work order syncs with Business Central, linking it to the correct customer account and contract terms. This sets the foundation for accurate billing and inventory updates.
2. Real-time parts management
Engineers often carry stock in their vans or collect parts from local depots. Business Central tracks inventory across all locations, including mobile stock. When parts are consumed on a job, the usage is recorded against the work order and deducted from ERP inventory in real time. This prevents stock discrepancies and supports automated replenishment.
3. Labour and time capture
Timesheets in Field Service feed directly into Business Central’s job costing and billing modules. This ensures every hour worked is accounted for and billed correctly. Automated workflows can flag overtime or additional labour for approval before invoicing, reducing disputes and improving transparency.
4. Pricing and contract compliance
Business Central holds master pricing and discount structures. By integrating with Field Service, engineers can access accurate pricing on-site, whether for parts or labour. This avoids undercharging and ensures compliance with service agreements, protecting margins and customer trust.
5. Automated invoicing
Once a work order is completed and approved, Business Central generates the invoice automatically based on recorded parts and labour. This eliminates manual data entry and accelerates billing cycles. Invoices can be sent electronically, improving cash flow and reducing administrative overhead.
Practical steps for implementation
To achieve seamless integration, follow these steps:
-
Map your processes: Document how work orders, inventory and billing currently flow. Identify gaps that cause delays or errors.
-
Enable standard connectors: Use Microsoft’s out-of-the-box integration between Dynamics 365 Field Service and Business Central to sync key entities like customers, work orders and invoices.
-
Configure approval workflows: Ensure additional labour or high-value parts require sign-off before invoicing to maintain control.
-
Train your teams: Engineers and finance staff should understand how integrated processes work to avoid manual workarounds.
-
Monitor KPIs: Track metrics such as invoice cycle time, unbilled items and inventory accuracy to measure success.
The payoff: efficiency and profitability
By integrating field service operations with ERP, businesses can achieve:
-
Reduced revenue leakage: Every part and hour worked is captured and billed accurately.
-
Faster cash flow: Automated invoicing shortens billing cycles and improves liquidity.
-
Accurate inventory: Real-time stock updates prevent shortages and reduce carrying costs.
-
Better customer experience: Transparent pricing and timely billing build trust and loyalty.
As Microsoft notes, “Connected service and finance processes enable organisations to deliver exceptional customer experiences while maximising profitability.” For field service businesses, this means turning operational complexity into financial clarity.
