Invoicing is often one of the most critical, and most time-consuming, steps in the lifecycle of a project. When data is spread across multiple systems or requires manual validation, billing becomes a bottleneck. Delays accumulate, errors creep in, and finance teams spend more time reconciling information than delivering value.
OMZY changes this dynamic by transforming invoicing into a seamless, integrated process. Instead of treating billing as a final step, disconnected from operations, OMZY embeds it directly into the project lifecycle. The result is a faster, more accurate, and far more predictable invoicing process that supports both operational efficiency and financial performance.
Reduce revenue leakage: A Single Source of Truth for Billing Data
Time entries, expenses, and project transactions are recorded inside Business Central and structured according to billing rules defined at the start of the project. By the time a billing cycle opens, the data is already organized and ready.
There is no need to re-enter data, pull reports from a separate system, or reconcile spreadsheets. Everything flows naturally into the invoicing process, which improves accuracy and saves time for both finance teams and project managers.
Flexible Billing Models for Every Contract Type
Professional service firms rarely bill every project the same way. OMZY is designed to accommodate that reality.
Time and Materials Billing
For projects billed on effort and expenses, OMZY captures hours worked and costs incurred in real time. Billable transactions are automatically flagged based on the rules configured for that project, and rates are applied consistently without manual lookups.
Fixed Fee and Lump-Sum Billing
For fixed-price engagements, OMZY supports lump-sum billing cycles that align with the contract terms. Finance teams can issue invoices on schedule without waiting to compile data from across the project.
Milestone Billing
Some contracts are tied to specific deliverables or project phases. OMZY supports milestone billing, allowing invoices to be generated when defined conditions or stages are reached rather than on a calendar cycle.
Mixed Billing within a Single Project
Many complex engagements combine multiple billing models. A project might include a fixed setup fee, time and materials work during delivery, and milestone payments tied to key sign-offs. OMZY handles this without manual workarounds or external tools, keeping all billing logic inside a single project record in Business Central.
The Impact on Cash Flow and Financial Performance
Streamlined billing has a direct effect on financial outcomes. When invoices can be generated as soon as transactions are approved, the time between project execution and client billing shrinks significantly.
For service-based organizations where revenue depends on timely billing, this acceleration supports stronger cash flow and more predictable revenue recognition. Finance directors gain real-time visibility into billing status rather than waiting for periodic summaries.
Accurate, detailed invoices also reduce disputes. Every billed amount can be traced back to specific time entries, expenses, or milestones, providing clear justification for clients and simplifying internal audits.

Project Billing as Part of the Broader Project Lifecycle
Billing does not happen in isolation. In OMZY, it is connected to every other stage of project delivery, from the original budget and cost tracking through resource utilization and forecasting.
This means that the same real-time data that helps a project manager monitor costs also feeds the invoicing process. There are no gaps between what has been delivered and what gets billed, and no approximations caused by incomplete or outdated information.
Key to Success: Billing Rules Defined at Project Setup
One of the key design decisions in OMZY is that billing logic is configured upfront. During project setup, teams define which transactions are billable, when invoices should be generated, and how they should be structured.
Once those rules are in place, the invoicing process becomes highly automated. Transactions that meet the predefined conditions are included in the invoice without additional manual steps. This consistency reduces errors and allows finance teams to handle higher invoice volumes without increasing workload.
